Borrow material shall be obtained from areas within the limits of the airport property but outside the normal limits of necessary grading , or from areas outside the airport. 152-1.3 Unsuitable Excavation. Any material containing vegetable or organic matter, such as muck, peat, organic silt, or sod shall be considered unsuitable for use in embankment construction . Material , when approved by the Engineer as suitable to support vegetation , may be used on the embankment slope . CONSTRUCTION METHODS 152-2.1 General. Before beginning excavation, grading , and embankment operations in any area , the area shall be completely cleared and grubbed in accordance with Item P-151. The suitability of material to be placed in embankments shall be subject to approval by the Engineer. All unsuitable material shall be disposed of in waste areas shown on the plans . All waste areas shall be graded to allow positive drainage of the area and of adjacent areas. The surface elevation of waste areas shall not extend above the surface elevation of Fort Worth Alliance Airport Runway Extension Project Earthwork Package 3 P-152-1 adjacent usable areas of the airport, unless specified on the plans or approved by the Engineer. When the Contractor's excavating operations encounter artifacts of historical or archaeological significance, the operations shall be temporarily discontinued . At the direction of the Engineer, the Contractor shall excavate the site in such a manner as to preserve the artifacts encountered and allow for their removal. Such excavation will be paid for as extra work. Those areas outside of the pavement areas in which the top layer of soil material has become compacted, by hauling or other activities of the Contractor shall be scarified ·and disked to a depth of 4 inches (100 mm), in order to loosen and pulverize the soil. If it is necessary to interrupt existing surface drainage, sewers or under-drainage, conduits, utilities, or similar underground structures, the Contractor shall be responsible for and shall take all necessary precautions to preserve them or provide temporary services. When such facilities are encountered, the Contractor shall notify the Engineer, who shall arrange for their removal if necessary. The Contractor shall, at his/her own expense , satisfactorily repair or pay the cost of all damage to such facilities or structures that may result from any of the Contractor's operations during the period of the contract. 152-2.2 EXCAVATION. No excavation shall be started until the work has been staked out by the Contractor and the Engineer has obtained elevations and measurements of the ground surface . All suitable excavated material shall be used in the formation of embankment, subgrade, or for other purposes shown on the plans. All unsuitable material shall be disposed of as shown on the plans. When the volume of the excavation exceeds that required to construct the embankments to the grades indicated, the excess shall be used to grade the areas of ultimate development or disposed of as directed . When the volume of excavation is not sufficient for constructing the fill to the grades indicated , the deficiency shall be obtained from borrow areas. The grade shall be maintained so that the surface is well drained at all times. When necessal}j_ temporary drains and drainage ditches shall be installed to intercept or divert surface water that may affect the work . a. Selective Grading. When selective grading is indicated on the plans, the more suitable material as designated by the Engineer shall be used in constructing the embankment or in capping the pavement subgrade . If, at the time of excavation , it is not possible to place this material in its final location, it shall be stockpiled in approved areas so that it can be measured for payment for rehandling as specified in paragraph 3 .3. b. Undercutting. Rock, shale, hardpan, loose rock , boulders, or other material unsatisfactory for safety areas , subgrades , roads , shoulders , or any areas intended for turfing shall be excavated to a minimum depth of 12 inches (300 mm), or to the depth specified by the Engineer, below the subgrade . Muck, peat, matted roots, or other yielding material, unsatisfactory for subgrade foundation , shall be removed to the depth specified . Unsuitable materials shall be disposed of at locations shown on the plans . This excavated material shall be paid for at the contract unit price per cubic yard (per cubic meter) for unclassified excavation . The excavated area shall be refilled with suitable material obtained from the grading operations or borrow areas and compacted to specified densities . The Ft. Worth Alliance Airport Alliance Airport Runway Extension Project Earthwork Package 3 P-152-2 necessary refilling will constitute a part of the embankment. Where rock cuts are made and refilled with selected material, any pockets created in the rock surface shall be drained in accordance with the details shown on the plans. c. Overbreak. Overbreak, including slides, is that portion of any material displaced or loosened beyond the finished work as planned or authorized by the Engineer. The Engineer shall determine if the displacement of such material was unavoidable and his/her decision shall be final. All overbreak shall be graded or removed by the Contractor and disposed of as directed; however, payment will not be made for the removal and disposal of overbreak that the Engineer determines as avoidable. Unavoidable overbreak will be classified as "Unclassified Excavation ." d. Removal of Utilities. The removal of existing structures and utilities required to permit the orderly progress of work will be accomplished by someone other than the Contractor, e.g ., the utility unless otherwise shown on the plans. All existing foundations shall be excavated for at least 2 feet (60 cm) below the top of subgrade or as indicated on the plans , and the material disposed of as directed. All foundations thus excavated shall be backfilled with suitable material and compacted as specified herein. e. Compaction Requirements. The subgrade under areas to be paved shall be compacted to a depth of 6 inches and to a density of not less than 95 percent of the maximum density as determined by ASTM D 1557. The material to be compacted shall be within +/-2 percent of optimum moisture content before rolled to obtain the prescribed compaction ( except for expansive soils). The in-place field density shall be determined in accordance with ASTM D 1556 or ASTM D 2167. Stones or rock fragments larger than 4 inches (100 mm) in their greatest dimension will not be permitted in the top 6 inches ( 150 mm) of the subgrade. The finished grading operations, conforming to the typical cross section, shall be completed and maintained at least 1,000 feet (300 m) ahead of the paving operations or as directed by the Engineer. In cuts, all loose or protruding rocks on the back slopes shall be barred loose or otherwise removed to line of finished grade of slope. All cut-and-fill slopes shall be uniformly dressed to the slope, cross section, and alignment shown on the plans or as directed by the Engineer. Blasting will be permitted only when proper precautions are taken for the safety of all persons, the work, and the property. All damage done to the work or property shall be repaired at the Contractor's expense. All operations of the Contractor in connection with the transportation, storage, and use of explosives shall conform to all state and local regulations and explosive manufacturers' instructions , with applicable approved permits reviewed by the Engineer. Any approval given, however, will not relieve the Contractor of his/her responsibility in blasting operations. Where blasting is approved , the Contractor shall employ a vibration consultant, approved by the Engineer, to advise on explosive charge weights per delay and to analyze records from seismograph recordings . The seismograph shall be capable of producing a permanent record of the three components of the motion in terms of particle velocity, and in addition shall be capable of internal dynamic calibration . Fort Worth Alliance Airport Runway Extension Project Earthwork Package 3 P-152-3 In each distinct blasting area , where pertinent factors affecting blast vibrations and their effects in the area remain the same , the Contractor shall submit a blasting plan of the initial blasts to the Engineer for approval. This plan must consist of hole size, depth, spacing, burden , type of explosives , type of delay sequence , maximum amount of explosive on any one delay period , depth of rock , and depth of overburden if any . The maximum explosive charge weights per delay included in the plan shall not be increased without the approval of the engineering . The Contractor shall keep a record of each blast fired-its date , time and location; the amount of explosives used , maximum explosive charge weight per delay period , and, where necessary, seismograph records identified by instrument number and location . These records shall be made available to the Engineer on a monthly basis or in tabulated form at other times as required . 152-2.3 BORROW EXCAVATION. Borrow area(s) within the a irport property are indicated on the plans. Borrow excavation shall be made only at these designated locations and within the horizontal and vertical limits as staked or as directed . When borrow sources are outside the boundaries of the airport property, it shall be the Contractor's responsibility to locate and obtain the supply, subject to the approval of the Engineer. The Contractor shall notify the Engineer, at least 15 days prior to beginning the excavation, so necessary measurements and tests can be made. All unsuitable material shall be disposed of by the Contractor. All borrow pits shall be opened up to expose the vertical face of various strata of acceptable material to enable obtaining a uniform product. Borrow pits shall be excavated to regular lines to permit accurate measurements , and they shall be drained and left in a neat, presentable cond ition with all slopes dressed uniformly. 152-2.4 DRAINAGE EXCAVATION. Drainage excavation shall consist of excavating for drainage ditches such as intercepting ; inlet or outlet , for temporary levee construction ; or for any other type as designed or as shown on the plans . The work shall be performed in the proper sequence with the other construction. All satisfactory material shall be placed in fills ; unsuitable material shall be placed in waste areas or as directed . Intercepting ditches shall be c_o__nstructed prior to starting adjacent excavation operations. All necessary work shall be performed to secure a fin ish true to line , elevation , and cross section . The Contractor shall maintain ditches constructed on the project to the required cross section and shall keep them free of debris or obstructions until the project is accepted . 152-2.5 PREPARATION OF EMBANKMENT AREA. Where an embankment is to be constructed to a height of 4 feet (120 cm) or less , all sod and vegetable matter shall be removed from the surface upon which the embankment is to be placed , and the cleared surface shall be completely broken up by plowing or scarifying to a minimum depth of 6 inches (150 mm). This area shall then be compacted as indicated in paragraph 2.6 . When the height of fill is greater than 4 feet ( 120 cm), sod not required to be removed shall be thoroughly disked and recompacted to the density of the surrounding ground before construction of embankment. Where embankments are to be placed on natural slopes steeper than 3 to 1, horizontal benches shall be constructed as shown on the plans. Ft. Worth All iance Airport Alliance Airport Runway Extension Project Earthwork Package 3 P-152-4 No direct payment shall be made for the work performed under this section. The necessary clearing and grubb ing and the quantity of excavation removed w ill be paid for under the respective items of work . 152-2.6 FORMATION OF EMBANKMENTS. Embankments shall be formed in successive horizontal layers of not more than 8 inches (200 mm) in loose depth for the full width of the cross section , unless otherwise approved by the Engineer. The grading operations shall be conducted, and the various soil strata shall be placed , to produce a soil structure as shown on the typical cross section or as d irected . Materials such as brush , hedge , roots , stumps , grass and other organic matter, shall not be incorporated or buried in the embankment. Operations on earthwork shall be suspended at any time when satisfactory results cannot be obtained because of rain , freezing , or other unsatisfactory conditions of the field . The Contractor shall drag , blade , or slope the embankment to provide proper surface drainage . The materia l in the layer shall be within +/-2 percent of optimum moisture content before rolling to obtain the prescribed compaction . In order to achieve a uniform moisture content throughout the layer, wetting or drying of the material and manipulation shall be required when necessary. Should the material be too wet to permit proper compaction or rolling , all work on all of the affected portions of the embankment shall be delayed until the material has dried to the required moisture content. Sprinkling of dry material to obtain the proper moisture content shall be done with approved equipment that will sufficiently distribute the water. Sufficient equipment to furnish the required water shall be available at all times . Samples of all embankment materials for testing , both before and after placement and compaction , will be taken for each 1,000 cubic yards. Based on these tests , the Contractor shall make the necessary correct ions and adjustments in methods , materials or moisture content in order to achieve the correct embankment density. Rolling operations shall be continued until the embankment is compacted to not less than 95 percent of maximum density for noncohesive soils , and 90 percent of maximum density for cohesive soils as determined by ASTM 01557 . Under all areas to be paved , the embankments shall be compacted to a depth of 6 inches and to a density of not less than 95 percent of the maximum density as determined by ASTM 01557 . On all areas outside of the pavement areas , no compaction will be required on the top 4 inches (100 mm). The in-place field density shall be determined in accordance with ASTM D 1556 or ASTM D 2167 . Compaction areas shall be kept separate , and no layer shall be covered by another until the proper density is obtained . During construction of the embankment , the Contractor shall route his/her equipment at all times , both when loaded and when empty , over the layers as they are placed and shall distribute the travel evenly over the entire width of the embankment. The equipment shall be operated in such a manner that hardpan , cemented gravel , clay , or other chunky soil material will be broken up into small particles and become incorporated with the othe r material in the layer. Fort Worth Alliance Airport Runway Extension Project Earthwork Package 3 P-152-5 In the construction of embankments, layer placement shall begin in the deepest portion of the fill; as placement progresses, layers shall be constructed approximately parallel to the finished pavement grade line. When rock and other embankment material are excavated at approximately the same time, the rock shall be incorporated into the outer portion of the embankment and the other material shall be incorporated under the future paved areas . Stones or fragmentary rock larger than 4 inches (100 mm) in their greatest dimensions will not be allowed in the top 6 inches ( 150 mm) of the subgrade . Rockfifl shall be brought up in layers as specified or as directed and every effort shall be exerted to fill the voids with the finer material forming a dense, compact mass. Rock or boulders shall not be disposed of outside the excavation or embankment areas, except at places and in the manner designated by the Engineer. When the excavated material consists predominantly of rock fragments of such size that the material cannot be placed in layers of the prescribed thickness without crushing , pulverizing or further breaking down the pieces, such material may be placed in the embankment as directed in layers not exceeding 2 feet (60 cm) in thickness. Each layer shall be leveled and smoothed with suitable leveling equipment and by distribution of spalls and finer fragments of rock. These type lifts shall not be constructed above an elevation 4 feet ( 120 cm) below the finished subgrade. Frozen material shall not be placed in the embankment nor shall embankment be placed upon frozen material. There will be no separate measurement of payment for compacted embankment, and all costs incidental to placing in layers, compacting , disking, watering , mixing, sloping, and other necessary operations for construction of embankments will be included in the contract price for excavation, borrow, or other items. 152-2.7 FINISHING AND PROTECTION OF SUBGRADE. After the subgrade has been substantially completed the full width shall be conditioned by removing any soft or other unstable material that will not compact properly. The resulting areas and all other low areas, holes or depressions shall be brought to grade with suitable select material. Scarifying, blading , rolling and other methods shall be performed to provide a thoroughly compacted subgrade shaped to the lines and grades shown on the plans . Grading of the subgrade shall be performed so that it will drain readily. The Contractor shall take all precautions necessary to protect the subgrade from damage . He/she shall limit hauling over the finished subgrade to that which is essential for construction purposes. All ruts or rough places that develop in a completed subgrade shall be smoothed and recompacted. No subbase, base, or surface course shall be placed on the subgrade until the subgrade has been approved by the Engineer. 152-2.8 HAUL. All hauling will be considered a necessary and incidental part of the work . Its cost shall be considered by the Contractor and included in the contract unit price for the pay of items of work involved .

If a change order has not been issued by the date upon which the Contractor's cost reduction proposal specifies that a decision should be made, or such other date as the Contractor may subsequently have requested in writing , such cost reduction proposal shall be deemed rejected. The Engineer shall be the sole judge of the acceptability of a cost reduction proposal and of the estimated net savings from the adoption of all or any part of such proposal. In determining the estimated net savings , the Engineer may disregard the contract bid prices if, in the Engineer's judgment such prices do not represent a fair measure of the value of the work to be performed or deleted. The Owner may require the Contractor to share in the Owner's costs of investigating a cost reduction proposal submitted by the Contractor as a condition of considering such proposal. Where such a condition is imposed , the Contractor shall acknowledge acceptance of it in writing .. Such acceptance shall constitute full authority for the Owner to deduct the cost of investigating a cost reduction proposal from amounts payable to the Contractor under the contract. If the Contractor's cost reduction proposal is accepted in whole or in part, such acceptance will be by a contract change order that shall specifically state that it is executed pursuant to this subsection . Such change order shall incorporate the changes in the plans and specifications which are necessary to permit the cost reduction proposal or such part of it as has been accepted and shall include any conditions upon which the Engineer's approval is based. The change order shall also set forth the estimated net savings attributable to the cost reduction proposal. The net savings shall be determined as the difference in costs between the original contract costs for the involved work items and the costs occurring as a result of the proposed change. The change order shall also establish the net savings agreed upon and shall provide for adjustment in the contract price that will divide the net savings equally between the Contractor and the Owner. 111-23 ... - -· - ,I, ~ ...... ;,. ,-· - -, .

The Contractor is responsible to the Owner for the conduct of all subcontractors it-employs on the project. The Contractor shall assure that all subcontractors are made aware of the requirements of the safety plan and that they implement and maintain all necessary measures . No deviation or modifications may be made to the approved safety plan unless approved in writing by the Owner or Engineer. 80-05 CHARACTER OF WORKERS, METHODS, AND EQUIPMENT . The Contractor shall, at all times, employ sufficient labor and equipment for prosecuting the work to full completion in the manner and time required by the contract , plans, and specifications. All workers shall have sufficient skill and experience to perform properly the work assigned to them . Workers engaged in special work or skilled work shall have sufficient experience in such work and in the operation of the equipment required to perform the work satisfactorily. Any person employed by the Contractor or by any subcontractor who violates any operational regulations and, in the opinion of the Engineer, does not perform his work in a proper and skillful manner or is intemperate or disorderly shall, at the written request of the Engineer, be removed 111-37 - - forthwith by the Contractor or subcontractor employing such person, and shall not be employed again in any portion of the work without approval of the Engineer. Should the Contractor fail to remove such persons or person, or fail to furnish suitable and sufficient personnel for the proper prosecution of the work , the Engineer may suspend the work by written notice until compliance with such orders . All equipment that is proposed to be used on the work shall be of sufficient size and in such mechanical condition as to met requirements of the work and to produce a satisfactory quality of work . Equipment used on any portion of the work shall be such that no injury to previously completed work , adjacent property, or existing airport facilities will result from its use . When the methods and equipment to be used by the Contractor in accomplishing the work are not prescribed in the contract, the Contractor is free to use any methods or equipment that will accomplish the work in conformity with the requirements of the contract, plans, and specifications . When the contract specifies the use of certain methods and equipment, such methods and equipment shall be used unless others are authorized by the Engineer. If the Contractor desires to use a method or type of equipment other than specified in the contract, he may request authority from the Engineer to do so. The request shall be in writing and shall include a full description of the methods and equipment proposed and of the reasons for desiring to make the change. If approval is given, it will be on the condition that the Contractor will be fully responsible for producing work in conformity with contract requirements. If, after trial use of the substituted methods or equipment, the Engineer determines that the work produced does not meet contract requirements, the Contractor shall discontinue the use of the substitute method or equipment and shall complete the remaining work with the specified methods and equipment. The Contractor shall remove any deficient work and replace it with work of specified quality, or take such other corrective action as the Engineer may direct. No change will be made in bas is of payment for the contract items involved nor in contract time as a result of authorizing a change in methods or equipment under this subsection. 80-06 TEMPORARY SUSPENSION OF THE WORK. The Owner shall have the authority to suspend the work wholly, or in part, for such period or periods as he may deem-Aecessary, due to unsuitable weather, or such other conditions as are considered unfavorable for the prosecution of the work, or for such time as is necessary due to the failure on the part of the Contractor to carry out orders given or perform any or all provisions of the contract. In the event that the Contractor is ordered by the Owner, in writing , to suspend work for some unforeseen cause not otherwise provided for in the contract and over which the Contractor has no control , the Contractor may be reimbursed for actual money expended on the work during the period of shutdown . No allowance will be made for anticipated profits. The period of shutdown shall be computed from the effective date of the Engineer's order to suspend work to the effective date of the Engineer's order to resume the work. Claims for such compensation shall be filed with the Engineer within the time period stated in the Engineer's order to resume work. The Contractor shall submit with his/her claim information substantiating the amount shown on the claim . The Engineer will forward the Contractor's claim to the Owner for consideration in accordance with local laws or ordinances. No provision of this article shall be construed as entitling the Contractor to compensation for delays due to inclement weather, for suspensions made at the request of the Owner, or for any other delay provided for in the contract, plans, or specifications . 111-38 - If it should become necessary to suspend work for an indefinite period, the Contractor shall store all materials in such manner that they will not become an obstruction nor become damaged in any way. He shall take every precaution to prevent damage or deterioration of the work performed and provide for normal drainage of the work . The Contractor shall erect temporary structures where necessary to provide for traffic on, to , or from the airport. 80-07 DETERMINATION AND EXTENSION OF CONTRACT TIME . The number of calendar or working days allowed for completion of the work shall be stated in the proposal and contract and shall be known as the CONTRACT TIME. Should the contract time require extension for reasons beyond the Contractor's control , it shall be adjusted as follows : a. CONTRACT TIME based on WORKING DAYS shall be calculated weekly by the Engineer. The Engineer will furnish the Contractor a copy of his/her weekly statement of the number of working days charged against the contract time during the week and the number of working days currently specified for completion of the contract (the original contract time plus the number of working days, if any, that have been included in approved CHANGE ORDERS or SUPPLEMENTAL AGREEMENTS covering EXTRA WORK). The Engineer shall base his/her weekly statement of contract time charged on the following considerations: (1) No time shall be charged for days on which the Contractor is unable to proceed with the principal item of work under construction at the time for at least 6 hours with the normal work force employed on such principal item. Should the normal work force be on a double-shift, 12 hours shall be used. Should the normal work force be on a triple-shift , 18 hours shall apply. Conditions beyond the Contractor's control such as strikes , lockouts, unusual delays in transportation, temporary suspension of the principal item of work under construction or temporary suspension of the entire work which have been ordered by the Owner for reasons not the fault of the Contractor, shall not be charged against the contract time . (2) The Engineer will not make charges against the contract-time prior to the effective date of the notice to proceed . (3) The Engineer will begin charges against the contract time on the first working day after the effective date of the notice to proceed. (4) The Engineer will not make charges against the contract time after the date of final acceptance as defined in the subsection titled FINAL ACCEPTANCE of Section 50 . (5) The Contractor will be allowed 1 week in which to file a written protest setting forth his/her objections to the Engineer's weekly statement. If no objection is filed within such specified time, the weekly statement shall be considered as acceptable to the Contractor. The contract time (stated in the proposal) is based on the originally estimated quantities as described in the subsection titled INTERPRETATION OF ESTIMATED PROPOSAL QUANTITIES of Section 20. Should the satisfactory completion of the contract require performance of work in greater quantities than those estimated in the proposal, the contract time shall be increased in the same proportion as the cost of the actually completed quantities bears 111-39 to the cost of the originally estimated quantities in the proposal. Such increase in contract time shall not consider either the cost of work or the extension of contract time that has been covered by change order or supplemental agreement and shall be made at the time of final payment. b. CONTRACT TIME based on CALENDAR DAYS shall consist of the number of calendar days stated in the contract counting from the effective date of the notice to proceed and including all Saturdays, Sundays, holidays, and nonwork days . All calendar days elapsing between the effective dates of the Owner's orders to suspend and resume all work , due to causes not the fault of the Contractor, shall be excluded . At the time of final payment, the contract time shall be increased in the same proportion as the cost of the actually completed quantities bears to the cost of the originally estimated quantities -in the proposal. Such increase in the contract time shall not consider either cost of work or the extension of contract time that has been covered by a change order or supplemental agreement. Charges against the contract time will cease as of the date of final acceptance. - - - - c. When the contract time is a specified completion date, it shall be the date on which all contract work shall be substantially completed . If the Contractor finds it impossible for reasons beyond his/her control to complete the work within the contract time as specified, or as extended in accordance with the provisions of this subsection, he may, at any time prior to the expiration of the contract time as extended , make a written request to the Engineer for an extension of time setting forth the reasons which he believes will justify the granting of his/her request. Requests for extension of time on calendar day projects, caused by inclement weather, shall be supported with National Weather Bureau data showing the actual amount of inclement weather exceeded which could normally be expected during the contract period. The Contractor's plea that insufficient time was specified is not a valid reason for extension of time. If the Engineer finds that the work was delayed because of conditions beyond the control and without the fault of the Contractor, he may extend the time for completion in such amount as the conditions justify. The extended time for completion shall then be in full force and effect, the same as though it were the original time for completion. 80-08 FAILURE TO COMPLETE ON TIME. For each calendar day or working day, as specified in the contract, that any work remains uncompleted after the contract time (including all extensions and adjustments as provided in the subsection titled DETERMINATION AND EXTENSION OF CONTRACT TIME of this Section) the sum specified in the contract and proposal as liquidated damages will be deducted from any money due or to become due the Contractor or his/her surety. Such deducted sums shall not be deducted as a penalty but shall be considered as liquidation of a reasonable portion of damages including but not limited to additional engineering services that will be incurred by the Owner should the Contractor fail to complete the work in the time provided in his/her contract. SCHEDULE LIQUIDATED DAMAGES COST ALLOWED CONSTRUCTION TIME The maximum construction time allowed for Schedules will be the sum of the time allowed for individual schedules but not more than 45 days. 111-40 Permitting the Contractor to continue and finish the work or any part of it after the time fixed for its completion, or after the date to which the time for completion may have been extended , will in no way operate as a wavier on the part of the Owner of any of its rights under the contract. 80-09 DEFAULT AND TERMINATION OF CONTRACT. The Contractor shall be considered in default of his/her contract and such default will be considered as cause for the Owner to terminate the contract for any of the following reasons if the Contractor: a. Fails to begin the work under the contract within the time specified in the "Notice to Proceed ," or -. b. Fails to perform the work or fails to provide sufficient workers, equipment or materials - - - - - to assure completion of work in accordance with the terms of the contract , or c. Performs the work unsuitably or neglects or refuses to remove materials or to perform anew such work as may be rejected as unacceptable and unsuitable, or d. Discontinues the prosecution of the work, or e. Fails to resume work which has been discontinued within a reasonable time after notice to do so, or f. Becomes insolvent or is declared bankrupt, or commits any act of bankruptcy or insolvency, or g. Allows any final judgment to stand against him unsatisfi~d for a period of 1 O days, or h. Makes an assignment for the benefit of creditors, or i. For any other cause whatsoever, fails to carry on the work in an acceptable manner. Should the Engineer consider the Contractor in default of the contract for any reason hereinbefore , he shall immediately give written notice to the Contractor and the Contractor's surety as to the reasons for considering the Contractor in default and the-Owner's intentions to terminate the contract. If the Contractor or surety, within a period of 1 O days after such notice, does not proceed in accordance therewith, then the Owner will, upon written notification from the Engineer of the facts of such delay, neglect, or default and the Contractor's failure to comply with such notice , have full power and authority without violating the contract, to take the prosecution of the work out of the hands of the Contractor. The Owner may appropriate or use any or all materials and equipment that have been mobilized for use in the work and are acceptable and may enter into an agreement for the completion of said contract according to the terms and provisions thereof, or use such other methods as in the opinion of the Engineer will be required for the completion of said contract in an acceptable manner. All costs and charges incurred by the Owner, together with the cost of completing the work under contract, will be deducted from any monies due or which may become due the Contractor. If such expense exceeds the sum which would have been payable under the contract, then the Contractor and the surety shall be liable and shall pay to the Owner the amount of such excess . 111-41 - - - 80-10 TERMINATION FOR NATIONAL EMERGENCIES . The Owner shall terminate the contract or portion thereof by written notice when the Contractor is prevented from proceeding with the construction contract as a direct result of an Executive Order of the President with respect to the prosecution of war or in the interest of national defense. When the contract, or any portion th e reof, is terminated before completion of all items of work in the contract, payment will be made for the actual number of units or items of work completed at the contract price or as mutually agreed for items of work partially completed or not started . No claims or loss of anticipated profits shall be considered . Reimbursement for organization of the work, and other overhead expenses , (when not otherwise included in the contract) and moving equipment and materials to and from the job will be considered , the intent being that an equitable settlement will be made with the Contractor. Acceptable materials, obtained or ordered by the Contractor for the work and that are not incorporated in the work shall, at the option of the Contractor, be purchased from the Contractor at actual cost as shown by receipted bills and actual cost records at such points of delivery as may be designated by the Engineer. Termination of the contract or a portion thereof shall neither relieve the Contractor of his/her responsibilities for the completed work nor shall it relieve his/her surety of its obligation for and concerning any just claim arising out of the work performed. 80-11 WORK AREA, STORAGE AREA AND SEQUENCE OF OPERATIONS . The Contractor shall obtain approval from the Engineer prior to beginning any work in all areas of the airport . No operating runway , taxiway, or Air Operations Area (AOA) shall be crossed, entered, or obstructed while it is operational. The Contractor shall plan and coordinate his/her work in such a manner as to insure safety and a minimum of hindrance to flight operations. Alf Contractor equipment and material stockpiles shall be stored a minimum or 400 feet from the centerline of an active runway. No equipment will be allowed to park within the approach area of an active runway at any time . No equipment shall be within 400 feet of an active runway at any time. END OF SECTION 80 111-42 - - - - - - SECTION 90 MEASUREMENT AND PAYMENT 90-01 MEASUREMENT OF QUANTITIES . All work completed under the contract will be measured by the Engineer, or his/her authorized representative s, using United States Customary Units of Measurement or the International System of Units . The method of measurement and computations to be used in determination of quantities of material furnished and of work performed under the contract will be those methods generally recognized as conforming to good engineering practice. Unless otherwise specified , longitudinal measurements for area computations will be made horizontally, and no deductions will be made for individual fixtures ( or leave -outs) having an area of 9 square feet (0.8 square meter) or less . Unless otherwise specified, transverse measurements for area computations will be the neat dimensions shown on the plans or ordered in writing by the Engineer. Structures will be measured according to neat lines shown on the plans or as altered to fit field conditions . Unless otherwise specified, all contract items which are measured by the linear foot such as electrical ducts, conduits, pipe culverts , underdrains , and similar items shall be measured parallel to the base or foundation upon which such items are placed. In computing volumes of excavation the average end area method or other acceptable methods will be used . The thickness of plates and galvanized sheet used in the manufacture of corrugated metal pipe , metal plate pipe culverts and arches, and metal cribbing will be specified and measured in decimal fraction of inches . The term "ton" will mean the short ton consisting of 2,000 pounds (907 kilograms) avoirdupois . All materials that are measured or proportioned by weights shall be weighed on accurate , approved scales by competent, qualified personnel at locations designed by the Engineer. If material is shipped by rail, the car weight may be accepted provided that only the actual weight of material is paid for. However, car weights will not be acceptable for material to be passed through mixing plants . Trucks used to haul material being paid for by weight shall be weighed empty daily at such times as the Engineer directs , and each truck shall bear a plainly legible identification mark. Materials to be measured by volume in the hauling vehicle shall be hauled in approved vehicles and measured therein at the point of delivery. Vehicles for this purpose may be of any size or type acceptable to the Engineer, provided that the body is of such shape that the actual contents may be readily and accurately determined . All vehicles shall be loaded to at least their water level capacity, and all loads shall be leveled when the vehicles arrive at the point of delivery. When requested by the Contractor and approved by the Engineer in writing , material specified to be measured by the cubic yard (cubic meter) may be weighed, and such weights will be 111-43 - .-. ·- - - converted to cubic yards ( cubic meters) for payment purposes . Factors for conversion from weight measurement to volume measurement will be determined by the Engineer and shall be agreed to by the Contractor before such method of measurement of pay quantities is used . Bituminous materials will be measured by the gallon (liter) or ton (kilogram). When measured by volume , such volumes will be measured at 60 F ( 15 C) or will be corrected to the volume at 60 F (15 C) using ASTM D 1250 for asphalts or ASTM D 633 for tars. Net certified scale weights or weights based on certified volumes in the case of rail shipments will be used as a basis of measurement, subject to correction when bituminous material has been lost from the car or the distributor, wasted, or otherwise not incorporated in the work. When bituminous materials are sh ipped by truck or transport, net certified weights by volume, subject to correction for loss or foaming, may be used for computing quantities. Cement will be measured by the ton (kilogram) or hundredweight (kilogram). Timber will be measured by the thousand feet board measure (M .F.B .M.) actually incorporated in the structure . Measurement will be based on nominal widths and thicknesses and the extreme length of each piece . The term ··lump sum" when used as an item of payment will mean complete payment for the work described in the contract. When a complete structure or structural unit (in effect, "lump sum" work) is specified as the unit of measurement, the unit will be construed to include all necessary fittings and accessories. Rental of equipment will be measured by time in hours of actual working time and necessary traveling time of the equipment within the limits of the work . Special equipment ordered by the Engineer in connection with force account work will be measured as agreed in the change order or supplemental agreement authorizing such force account work as provided in the subsection titled PAYMENT FOR EXTRA AND FORCE ACCOUNT WORK of this section. When standard manufactured items are specified such as fence , wire, plates, rolled shapes, pipe conduit, etc., and these items are identified by gage, unit weight, section dimensions, etc ., such identification will be considered to be nominal weights or dimensions . Unless more stringently controlled by tolerances in cited specifications, manufacturing tolerances established by the industries involved will be accepted . Scales for weighing materials which are required to be proportioned or measured and paid for by weight shall be furnished, erected, and maintained by the Contractor, or be certified permanently installed commercial scales . Scales shall be accurate within one-half percent of the correct weight throughout the range of use . The Contractor shall have the scales checked under the observation of the inspector before beginning work and at such other times as requested. The intervals shall be uniform in spacing throughout the graduated or marked length of the beam or dial and shall not exceed one-tenth of 1 percent of the nominal rated capacity of the scale, but not less than 1 pound ( 454 grams). The use of spring balances will not be permitted . 111-44 , ... - - - - Beams, dials, platforms, and other scale equipment shall be so arranged that the operator and the inspector can safely and conveniently view them . Scale installations shall have available ten standard 50-pound (2.3 kilogram) weights for testing the weighing equipment or suitable weights and devices for other approved equipment. Scales must be tested for accuracy and serviced before use at a new site . Platform scales shall be installed and maintained with the platform level and rigid bulkheads at each end . Scales '' overweighing" (indicating more than correct weight) will not be permitted to operate, and all materials received subsequent to the last previous correct weighting-accuracy test will be reduced by the percentage of error in excess of one-half of 1 percent. In the event inspection reveals the scales have been "underweighing" (indicating less than correct weight), they shall be adjusted, and no additional payment to the Contractor will be allowed for materials previously weighed and recorded. All costs in connection with furnishing, installing, certifying, testing, and maintaining scales; for furnishing check weights and scale house; and for all other items specified in this subsection, for the weighing of materials for proportioning or payment, shall be included in the unit contract prices for the various items of the project. When the estimated quantities for a specific portion of the work are designated as the pay quantities in the contract , they shall be the final quantities for which payment for such specific portion of the work will be made, unless the dimensions of said portions of the work shown on the plans are revised by the Engineer. If revised dimensions result in an increase or decrease in the quantities of such work, the final quantities for payment will be revised in the amount represented by the authorized changes in the dimensions. 90-02 SCOPE OF PAYMENT. The Contractor shall receive and accept compensation provided for in the contract as full payment for furnishing all materials, for performing all work under the contract in a complete and acceptable manner, and for all risk, loss, damage, or expense of whatever character arising out of the nature of the work or the prosecution thereof, subject to the provisions of the subsection titled NO WAIVER OF LEGAL RIGHTS of Section 70 . When the "basis of payment" subsection of a technical specification requires that the contract price (price bid) include compensation for certain work or material essential to the item, this same work or material will not also be measured for payment under any other contract item which may appear elsewhere in the contract, plans, or specifications . 90-03 COMPENSATION FOR ALTERED QUANTITIES . When the accepted quantities of work vary from the quantities in the proposal, the Contractor shall accept as payment in full, so far as contract items are concerned, payment at the original contract price for the accepted quantities of work actually completed and accepted . No allowance, except as provided for in the subsection titled AL TERA TION OF WORK AND QUANTITIES of Section 40 will be made for any increased expense, loss of expected reimbursement, or loss of anticipated profits suffered or claimed by the Contractor which results directly from such alterations or indirectly from his/her unbalanced allocation of overhead and profit among the contract items, or from any other cause. 111-45 90-04 PAYMENT FOR OMITTED ITEMS . As specified in the subsection titled OMITTED ITEMS of Section 40 , the Engineer shall have the right to omit from the work (order nonperformance) any contract item , ex cept major contract items , in the be st interest of the Owner. Should the Engineer omit or order nonperformance of a contract item or portion of such item from th e w o rk , th e Contra ctor sha ll ac ce pt payment in full at the contract pri ce s for a ny w ork actually completed and acceptable prior to the Engineer's order to omit or nonperform such contract item . Acceptable materials ordered by the Contractor or delivered on the work prior to the date of the -Engineer's order will be paid for at the actual cost to the Contractor and shall thereupon become the property of the Owner. ·- - - - In add ition to the reimbursement hereinbefore provided, the Contractor shall be reimbursed for all actual costs incurred fo r the purpose of performing the omitted contract item prior to the date of the Engineer's order. Such additional costs incurred by the Contractor must be directly related to the deleted contract item and shall be supported by certified statements by the Contractor as to the nature the amount of such costs . 90-05 PAYMENT FOR EXTRA AND FORCE ACCOUNT WORK . Extra work, performed in accordance with the subsection titled EXTRA WORK of Section 40, will be paid for at the contract prices or agreed prices specified in the change order or supplemental agreement authorizing the extra work. When the change order or supplemental agreement authorizing the extra work requires that it be done by force account, such force account shall be measured and paid for based on expended labor, equipment, and materials plus a negotiated and agreed upon allowance for overhead and profit. a. Miscellaneous . No additional allowance will be made for general superintendence, the use of small tools , or other costs for which no specific allowance is herein provided . b. Comparison of Record . The Contractor and the Engineer shall compare records of the cost of force account work at the end of each day. Agreement shall . be indicated by signature of the Contractor and the Engineer or their duly authorized representatives . c. Statement. No payment will be made for work performed on a force account basis until the Contractor has furnished the Engineer with duplicate itemized statements of the cost of such force account work detailed as follows : (1) Name, classification , date, daily hours , total hours, rate and extension for each laborer and foreman . (2) Designation, dates , daily hours, total hours, rental rate , and extension for each unit of machinery and equipment. (3) Quantities of materials , prices , and extensions . (4) Transportation of materials . (5) Cost of property damage, liability and workman's compensation insurance premiums , unemployment insurance contributions, and social security tax . 111-46 - - -- - - - Statements shall be accompanied and supported by a receipted invoice for all materials used and transportation charges . However, if materials used on the force account work are not specifically purchased for such work but are taken from the Contractor's stock , then in lieu of the invoices the Contractor sh all furnish an affidavit certifying that such materials were taken from his/her stock, that the quantity claimed was actually used , and that the price and transportation claimed repre sent th e actu al cost to the Contractor. 90-06 PARTIAL PAYMENTS . Partial payments will be made at least once each month as the work progresses . Said payments will be based upon estimates prepared by the Engineer of the value of the work perform ed and materials complete in place in accordance with the contract , plans, and specifications . Such partial payments may also include the delive red actual cost of those materials stockpiled and stored in accordance with the subsection titled PAYMENT FOR MATERIALS ON HAND of this section. No partial payment will be made when the amount due the Contractor since the last estimate amounts to less than five hundred dollars . From the total of the amount determined to be payable on a partial payment, 1 O percent of such total amount will be deducted and retained by the Owner until the final payment is made, except as may be provided ( at the Contractor's option) in the subsection titled PAYMENT OF WITHHELD FUNDS of this section. The balance (90 percent) of the amount payable , less all previous payments, shall be certified for payment. Should the Contractor exercise his/her option , as provided in the subsection titled PAYMENT OF WITHHELD FUNDS of this section , no such 10 percent retainage shall be deducted . When not less than 95 percent of the work has been completed, the Engineer may, at the Owner's discretion and with the consent of the surety, prepare an estimate from which will be retained an amount not less than twice the contract value or estimated cost, whichever is greater, of the work remaining to be done . The remainder, less all previous payments and deductions, will then be certified for payment to the Contractor. It is understood and agreed that the Contractor shall not be entitled to demand or receive partial payment based on quantities of work in excess of those provided in the proposal or covered by approved change orders or supplemental agreements, except when such excess quantities have been determined by the Engineer to be a part of the final quantity for the item of work in question . No partial payment shall bind the Owner to the acceptance of any materials or work in place as to quality or quantity . All partial payments are subject to correction at the time of final payment as provided in the subsection titled ACCEPTANCE AND FINAL PAYMENT of this section . The Contractor shall deliver to the Owner a complete release of all claims for labor and material arising out of this contract before the final retained percentage or final payment is made . If any subcontractor or supplier fails to furnish such a release in full , the Contractor may furnish a bond or other collateral satisfactory to the Owner to indemnify the Owner aga inst any potential lien or other such claim . The bond or collateral shall include all costs , expenses, and attorney fees the Owner may be compelled to pay in discharging any such lien or claim . 90-07 PAYMENT FOR MATERIALS ON HAND. Partial payments may be made to the extent of the delivered cost of materials to be incorporated in the work, provided that such materials 111-47 - - - - meet the requirements of the contract, plans, and specifications and are delivered to acceptable sites on the airport property or at other sites in the vicinity that are acceptable to the Owner. Such delivered costs of stored or stockpiled materials may be included in the next partial payment after the following conditions are met: a. The material has been stored or stockpiled in a manner acceptable to the Engineer at or on an approved site . b. The Contractor has furnished the Engineer with acceptable evidence of the quantity and quality of such stored or stockpiled materials . c. The Contractor has furnished the Engineer with satisfactory evidence that the material and transportation costs have been paid. d.

The Contractor shall obtain the written consent of the surety to such agreement. 111-48 - - -- -" 90-09 ACCEPTANCE AND FINAL PAYMENT . When the contract work has been accepted in accordance with the requirements of the subsection titled FINAL ACCEPTANCE of Section 50, the Engineer will prepare the final estimate of the items of work actually performed . The Contractor shall approve the Engineer's final estimate or advise the Engineer of his/her objections to the final estimate which are based on disputes in measurements or computations of the final quantities to be paid under the contract as amended by change order or supplemental agreement. The Contractor and the Engineer shall resolve all disputes (if any) in the measurement and computation of final quantities to be paid within 30 calendar days of the Contractor's receipt of the Engineer's final estimate . If, after such 30-day period , a dispute still exists , the Contractor may approve the Engineer's estimate under protest of the quantities in dispute, and such disputed quantities shall be considered by the Owner as a claim in accordance with the subsection titled CLAIMS FOR ADJUSTMENT AND DISPUTES of Section 50 . After the Contractor has approved , or approved under protest, the Engineer's final estimate, final payment will be processed based on the entire sum, or the undisputed sum in case of approval under protest, determined to be due the Contractor less all previous payments and all amounts to be deducted under the provisions of the contract. All prior partial estimates and payments shall be subject to correction in the final estimate and payment. If the Contractor has filed a claim for additional compensation under the prov1s1ons of the subsection titled CLAIMS FOR ADJUSTMENTS AND DISPUTES of Section 50 or under the provisions of this subsection, such claims will be considered by the Owner in accordance with local laws or ordinances . Upon final adjudication of such claims, any additional payment determined to be due the Contractor will be paid pursuant to a supplemental final estimate . END OF SECTION 90 111-49 \ SECTION 100 CONTRACTOR QUALITY CONTROL PROGRAM 100-01 GENERAL. When the specification requires a Contractor Quality Control Program, the Contractor shall establish , provide, and maintain an effective Quality Control Program that details the methods and procedures that will be taken to assure that all materials and completed construction required by this contract conform to contract plans , technical specifications and other requirements, whether manufactured by the Contractor, or procured from subcontractors or vendors . Although guidelines are established and certain minimum requirements are .. specified herein and elsewhere in the contract technical specifications, the Contractor shall assume full responsibility for accomplishing the stated purpose . - .. - The intent of this section is to enable the Contractor to establish a necessary level of control that will : a. Adequately provide for the production of acceptable qual ity materials . b. Provide sufficient information to assure both the Contractor and the Engineer that the specification requirements can be met. c. Allow the Contractor as much latitude as possible to develop his or her own standard of control. The Contractor shall be prepared to discuss and present, at the preconstruction conference, his/her understanding of the quality control requirements . The Contractor shall not begin any construction or production of materials to be incorporated into the completed work until the Quality Control Program has been reviewed by the Engineer. No partial payment will be made for materials subject to specific quality control requirements until the Quality Control Program has been reviewed . The quality control requirements contained in this section and elsewhere in the contract technical specifications are in -addition to and separate from the acceptance testing requirements . Acceptance testing requirements are the responsibility of the Engineer. 100-02 DESCRIPTION OF PROGRAM. a. General Description.

END OF SECTION 100 111-56 SECTION 110 METHOD OF ESTIMATING PERCENTAGE OF MATERIAL WITHIN SPECIFICATION LIMITS (PWL) 110-01 GENERAL. When the specifications provide for acceptance of material based on the method of estimating percentage of material within specification limits (PWL), the PWL will be determined in accordance with this section . All test results for a lot will be analyzed statistically to determine the total estimated percent of the lot that is within specification limits . The PWL is computed using the sample average (X) and sample standard deviation (Sn) of the specified number (n) of sublets for the lot and the specification tolerance limits, L for lower and U for upper, for the particular acceptance parameter. From these values , the respective Quality index(s), QL for Lower Quality Index and/or Ou for Upper Quality Index, is computed and the PWL for the lot for the specified n is determined from Table 1. All specification limits specified in the technical sections shall be absolute values . Test results used in the calculations shall be to the significant figure given in the test procedure. There is some degree of uncertainty (risk) in the measurement for acceptance because only a small fraction of production material (the population) is sampled and tested . This uncertainty exists because all portions of the production material have the same probability to be randomly sampled . The Contractor's risk is the probability that material produced at the acceptable quality level is rejected or subjected to a pay adjustment. The Owner's risk is the probability that material produced at the rejectable quality level is accepted. IT IS THE INTENT OF THIS SECTION TO INFORM THE CONTRACTOR THAT, IN ORDER TO CONSISTENTLY OFFSET THE CONTRACTOR'S RISK FOR MATERIAL EVALUATED, PRODUCTION QUALITY (USING POPULATION AVERAGE AND POPULATION STANDARD DEVIATION), MUST BE MAINTAINED AT THE ACCEPTABLE QUALITY SPECIFIED OR HIGHER. IN ALL CASES , IT IS THE RESPONSIBILITY OF THE CONTRACTOR TO PRODUCE AT QUALITY LEVELS THAT WILL MEET THE SPECIFIED ACCEPTANCE CRITERIA WHEN SAMPLED AND TESTED AT THE FREQUENCIES SPECIFIED. 110-02 METHOD FOR COMPUTING PWL. The computational sequence for computing PWL is as follows: a. Divide the lot into n sublets in accordance with the acceptance requirements of the specification. b . Locate the random sampling position within the sublot in accordance with the requirements of the specification . c. Make a measurement at each location, or take a test portion and make the measurement on the test portion in accordance with the testing requirements of the specification . d. Find the sample average (X) for all sublot values within the lot by using the following formula: Where :X = Sample average of all sublot values within a lot x1 , x2 = Individual sublot values n = Number of sublets 111-57 e. Find the sample standard deviation (Sn) by use of the following formula : Sn= [(d /+d /+d /+ ... d/)l(n-1)]112 Where :Sn = Sample standard deviation of the number of sublet values in the set average value X d 1 , d2, = Deviations of the individual sublet values x 1 , x2, ... from the that is : d, = (x , -X), d2 = (X 2 -X) ... dn = (Xn -X) n = Number of sublets f. For single sided specification limits (i.e., L only), compute the Lower Quality Index Q L by use of the following formula: QL = (X -L) / Sn Where : L = specification lower tolerance limit Estimate the percentage of material within limits (PWL) by entering Table 1 with QL, using the column appropriate to the total number (n) of measurements . If the value of QL falls between values shown on the table , use the next higher value of PWL. g. For double-sided specification limits (i.e . L and U), compute the Quality Indexes QL and Ou by use of the following formulas : and Ou = (U -X) / Sn Where : L and U = specification lower and upper tolerance limits Estimate the percentage of material between the lower (L) and upper (U) tolerance limits (PWL) by entering Table 1 separately with QL and Ou, using the column appropriate to the total number (n) of measurements, and determining the percent of material above PL and percent of material below Pu for each tolerance limit. If the values of QL fall between values shown on the table, use the next higher value of PL or Pu. Determine the PWL by use of the following formula : Project: Test Item: PWL =(Pu+ PL) -100 Where : PL = percent within lower specification limit Pu = percent within upper specification limit EXAMPLE OF PWL CALCULATION Example Project Item P-401, Lot A.

I I : l I _j r -t; I GEOTECHNICAL INVESTIGATION ALLIANCE AIRPORT RUNWAY EXTENSION-PHASE I FORT WORTH, TEXAS 1.0 INTRODUCTION 1.1 PROJECT DESCRIPTION The project consists of extending Runway 16L-34R to the north by 1,400 feet to a total length of 11,000 feet and extending Runway 16R -34l, also to the north by 2,67 5 feet to a total length of 11,000 feet. Associated with the runway extensions will be the extension to Taxiway A and the Aircraft Rescue and · Fire Fighting (ARFF) Road and drainage improvements . A drainage channel with a flow line varying from 5 to 25 feet below exist ing grades, is to be located west and north of the embankment for the runway extension. The runway extension will involve relocation of Highway FM 156 and a Burlington Northern Santa Fe (BNSF) Railway spur. The project will be constructed in three phases . Phase I will consist of the construction of the embankment north of FM 15.6. Embankment heights will be up to 48 feet in the area of I the proposed runway extension . The major part of the embankment construction will take place in this phase . Approximately 2,756, 000 cubic yards of embankment will be constructed . 1.2 PURPOSE AND SCOPE The purposes of this investigation were to: · 1. Evaluate the soil, rock and groundwater conditions on the subject site . 2. Evaluate the pertinent engineering properties of the encountered deposits. 3. Calculate settlement of the embankment and supporting soils . 4. Check that the embankment side slopes will have an adequate factor of safety against slope failure based on the final grading plan and cross-sections provided by the client. 5. Provide compaction recommendations. 6. Discuss the presence of groundwater and the impact of groundwater on construction. This report was prepared in general accordance with our Proposal No. P01-2157FE dated October 5, 2001. DE04-076 Page 1 TERRA-MAR r .L I C ! • I ; f · I : ! 2.0 FIELD INVESTIGATION Fifty -one borings were drilled at this site at the approximate locations shown on the Plan of Borings, Figure 1. The borings were terminated at depths of 1 O to 20 feet after penetrating at least 5 feet into the tan weathered limestone. The results of the field investigation are presented on the Logs of Borings, Figures 2 through 52. A key to the descriptive terms and symbols used on the logs is presented on Figure 53 . Geologic profiles are presented on Figures 54 through 60 . A truck-mounted drill rig and an All Terrain Vehicle (A TV) were used to advance the borings and to obtain sampl es for laboratory evaluation . Undisturbed samples of cohesive soils were obtained continuously to a depth of 5 feet; samples were obtained at a depth of 7 to 8 feet and 9 to 1 O feet and at 5-foot intervals thereafter with standard, tube samplers . The samples were extruded in the field, logged, sealed, and packaged to protect them from disturbance and to maintain their in-situ moisture content during transportation to our laboratory . The borings were backfilled with auger cuttings following completion of the field investigation. Texas Department of Transportation (TxDOT) Cone Penetrometer Tests were performed to evaluate the bearing properties of the limestone and shale. This test consists of measuring the penetration of a 3-inch-diameter cone driven by a 170-pound hammer falling a distance of 24 inches. The cone penetrometer test results are tabulated on the boring logs. Auger borings were performed in the vicinity of Boring 8-55 (borrow source, Refer to TMI Report No .

A brief description of the stratigraphy encountered in the borings is presented below. The depths indicated on the boring logs refer to the depth from the ground surlace that was present at the time of the investigation. Boundaries between the various soil/rock types are approximate . Layer(s) of clay and silty clay were encountered from the ground surface to depths of 1 to 16 feet followed by limestone to the boring termination depths of 1 O to 20 feet. In Borings B-26 and B-3q, gray limestone was underlain by gray shale to the boring termination depth. In Borings 8-29, B-31, B-32, B-37, B-43, B-47 and 8 ~51, weathered limestone was under1ain by shale to the boring termination depth . A layer of severely weathered limestone was encountered on top of the weathered limestone in some of the borings .. Clay fill material was encountered in Borings B-32, B-46, and B-47 to depths of 3 to 5 .5 feet. Limestone was encountered between elevation 668 .882 elevation 697.919 in the borings . The clays are highly plastic with liquid limits (LL) ranging between 50 -and 72, and plasticity indices (Pl) ranging betwe en 32 and 50. The clays exhibited unconfined compression tests ranging between 0.4 and 2 .1 tsf . The silty clays are moderately expansive with LL's ranging between 27 and 43, and Pl's ranging between 9 and 29. The silty clays exhibited unconfined compression strengths of 1.4 and 2 .0 tsf. The clay fill materials are highly DE04-076 Page3 TERRA-MAR I t-· r f expansive with LL's of 54 and 62, and Pl's of 37 and 42 . The clay fill materials exhibited unconfined compression strengths of 0.4 and 1.2 tsf. TCP test results in weathered limestone ranged between 100 blows/0.25 inches and 100 blows/7.0 inches . TCP test results in gray unweathered limestone ranged between 100 blows/0.5 inches and 100 blows/3 .25 inches and TCP test results in shale ranged between 100 blows/1 .0 inch and 100 blows/4.75 inches . The soil from the planned borrow source exhibited a maximum dry density of 121 pounds per cubic foot with an optimum moisture content of 11 .3 percent. Based on the consolidation tests, clays exhibited preconsolidation pressures ranging between 0.6 and 2.3 tsf with compression index ranging between 0.23 and 0.30 and recompression index ranging between 0 .06 and 0.10 . The silty clay exhibited a preconsolidation pressure of 1.8 tsf with a compression index of 0.14 and a recompression index of 0.04. Soil from borrow source exhibited a preconsolidation pressure ranging between 4.0 and 6.05 tsf with a compression index of 0.09 and 0.10 . The clays encountered in the borings exhibited an effective angle of Internal friction ranging between 26 .1 and 28 .8 degrees with cohesion ranging between 0.6 psi and 2.1 psi. The soil from the borrow area exhibited angle of internal friction ranging between 24 and 28.4 degrees with cohesion ranging between 462 and 769 psf. 4.2 GROUNDWATER CONDITIONS Groundwater seepage was encountered in Borings 8-4 through 8-7, 8-17 through B-19, 8- 24 through B-26, B-29, 8-36, and 8-45 at depths ranging between 2 and 1 O feet during drilling operations. The groundwater level after completion of the drilling operations ranged between 2 and 13.6 feet with the exception of Borings 8-24, 8-26, and 8-36, which were dry at completion of drilling operations. These borings are located near the creek. It is not possible to determine the level of the groundwater table based upon water level observations in boreholes during drilling. In addition, the subsurface water conditions will change with variations in the amount of precipitation, evaporation, and surface water runoff.

Settlement analysis has been performed to determine the anticipated se ttlement of the embankment and the underlying supporting soils. Th e parameters obtained in th e conso lidation tests were utilized in determining the anticipated settlement. Th e following Table 1 lists the embankment height and the anticipated se ttlem ent of th e embankment assuming that borrow material used for co n stru c tin g th e e mb ankm en t will conform to the specifications provided in Section 6 .1.

Similarly tor a 30 feet high embankment 50 percent of the settlement will take place in about 6 months and 90 percent settlement in about 2 years. 5.2 SLOPE STABILITY ANALYSES A global stability analysis was performed to check that the embankment side slopes would have an adequate factor of safety against slope failure based on the fin al grading plan and cross-sections provided by the client. The stability calculations were performed using the software program Slope/W developed by Geo-Slope. The embankment side -slopes, subsurface stratigraphy, design soil parameters, computed factor of safety and the most critical failure surface for the embankment are indicated on Figures 77 and 78 . The slope stability analyses indicates that the embankment side slopes have a computed safety factor of at least 3.0 . This factor is considered to be acceptable. Accordingly, the embankment is considered to have an adequate factor of safety with respect to slope stability. DE04-076 Page 6 TERRA-MAR I i .. _ [. I : I l I I . t -I: 6.0 EARTHWORK GUIDELINES 6.1 SUBGRADE PREPARATION Before beginning excavation, grading, and embankment operations in any area, the area shall be cleared of trash, debris, and organic material. Following clearing operations, the subgrade should be scarified to a depth of 6 inches and recompacted within two percent (plus or minus) of th e optimum water content to a minimum of 95 percent of the maximum density as determined by ASTM D 1557 . Soft or other unstable material, which will not c omp ac t properly, should be re moved to a firm subgrade. The resulting areas and all other low areas, holes or depressions shall be brought to grade with excavated material or ott-site borrow mat erial. 6.2 OFF-SITE BORROW EMBANKMENT Material that meets any of the following shall not be utilized as Off-Site Borrow Embankment: • Material that is high plasticity -classified as CH by the Unified Soil Classification System . • Material that has a liquid limit greater than 50. • Material that has a plasticity index greater than 22 (according to ASTM D 2487). • Material that has a CSR less than 20 when tested -according to ASTM D 1883 (at optimum moisture content and 95 percent of Maximum Dry Unit Weight per ASTM D 1557). Off-Site Borrow Embankment material shall be processed to meet the size/gradation requirements as follows. Sieve Sizes 3~1nch 1-lnch No. 4 No . 16 Percentage by Dry-Weight Passing Sieve 100 70-100 30-70 14-40 We recommend that sulfate tests be performed for the upper fill material under the paving to determine if sulfates are present. Lime should not be used to stabiiize this material if sulfates are present as lime would cause heave instead of stabilizing the material. 6.3 FORMATION OF EMBANKMENT AND COMPACTION REQUIREMENTS Embankments shall be farmed in successive near horizontal layers of not more than 8 inches in loose depths for the fuli width of the cross section . Layer placement shall begin in the deepest portion of the fill; as placement progresses, layers shall be constructed DE04-076 Page 7 TERRA~MAR I L I I ~ [. -I app roxi mately p aral le l to th e f ini she d p avement grad e lin e.
