DISCUSSION: The North Holly High Service Pump Station was constructed in 1892 while the North Holly Water Treatment Plant was constructed in 1912 . Since that time , numerous expansions , rehabilitations and improvements have been made to the treatment, pumping and piping facilities at North Holly . The majority of the existing pump station discharge piping at the North Holly Water Treatment Plant was installed in the 1940s. A portion of the pipe is buried and a portion is located underground in reinforced concrete tunnels constructed in the 1930s. Pressures in these pipelines generally range from 95 to 105 psi. With pressures this high , a major leak or pipe break would result in significant damage to the plant facilities and reduce the capability to meet water demands until repairs are made. On June 19 , 2007 , (M&C C-22199) City Council authorized the execution of an Engineering Agreement for the North and South Holly Water Treatment Plant Condition Assessment. This assessment recommended replacement of the pump station discharge piping due to the age , condition , the difficulty in making repairs and the consequences should a break occur. On November 16 , 2010 , (M&C C-24602) City Council authorized the City Manager to execute an Engineering Agreement with Kimley Horn and Associates , Inc., for the design of the North Holly High Service Pump Station Discharge Pipe Replacement Project. The project was advertised for bid in the Fort Worth Star-Telegram on April 14 , 2011 and April 21 , 2011.

The Owner will , after receipt of s uch justification and s upporting evidence, make findings of fact and will advise the Contractor in writing th ereof. If the Owner finds that the Contractor is entitled to any extension of any Contract completion date , the Owner's determination as to the total number of days extension shall be based upon the currently approved CPM schedule and on all data relevant to the extension. Such data sha ll be included in the next updating of the schedule. Actual delays in activities which, according to the CPM schedu le , do not affect any Contract completion date shown by the critical path in the network will n o t be the basis for a change therein . E. Each request for change in Contract completion date shall be submitted by the Contractor to the Owner within 30 days after the be g inning of the delay for which a time extension is requested but before the date of final payment under this Contract. No time extension will be granted for requests which are not subm itted within the foregoing time limit. 1. From time to time it may be necessary for the Contract schedule Or completion time to be adjusted by the Owner to reflect the effects of job conditions, weather, technical difficulties , strikes, unavoidable delays on the part of the Owner or its representatives, and other unforeseeable conditions which may indicate schedule adjustments or completion time extensions . Under such conditions, the Owner will direct the Contractor to reschedule the work or Contract completion time to reflect the changed conditions, and the Contractor shall revise his sc hedule accordingly. No additional compensation will be made to the Contractor for such schedu le changes except for unavoidable overall contract time extensions beyond the actual completion of unaffected work, in which case the Contractor shall take all possible action to minimize any time extension and any additional cost to the Owner. Available float time in the CPM sc hedule may be used by the Owner as well as by the Contractor. F . Float or slack time is defined as the amount of time betv.een the earliest s tart date and the latest start date o r between the earliest finish date and the latest finish date of a chain of activities on the CPM. Float or s l~ck time is no t for the exclusive use or benefit of either the Contractor or the Owner. Contractor's work shall proceed acco rding to early start dates, and the Owner shall have the right to re serve and apportion flo a t time according to the needs of the project. The Contractor acknowledges and agrees that actual delays , affecting paths of activities containing float time, will not have any affect upon contract completion times , providing that the actual delay does not exceed the fl oat time associated with those activities. 1.09 COO RD INA TING SCHEDULES WITH OTHER CONTRACT SCHEDULES A. Where work is to be performed under this Contract concurrently with or contingent upon work performed on the same facilities or area under other contracts, the Contractor's CPM Schedule shall be coordinated with the schedules of the other contracts. The Contractor shall obtain the schedules of the o ther appropriate contracts from the Owner for the preparation and updatLng of his CPM schedule and s hall make the required changes in his sc hedule when indicated by changes in corresponding schedu le s .

D. E. F. Concrete designated to be removed to specific limits as shown on the Drawings or directed by the Engineer, shall be done by line drilling at limits followed by chipping or jack-hammering as appropriate in areas where concrete is to be taken out. Remove concrete in such a manner that surrounding concrete or existing reinforcing to be left in place and existing in place equipment is not damaged. Sawcutting at limits of concrete to be removed sha ll only be done if indic a ted on the Drawings, or after obtaining written approval from the Engi neer. Where existing reinforcing is exposed due to saw cutting/core drilling a nd no new material is to be placed on the sawcut surface, a coating or s urface treatment of epoxy paste shall be applied to the entire cut surface to a thickness of 1/2-in. Rebar s hall be drilled and grinded to establish minimum cover requirements prior to application of the s urface treatment as detailed in the Drawings. Ii:i all cases where the joint between new concrete or grout and existing concrete will be exposed in the finished work , except as otherwise shown or spec ified , the joint shall be grooved and grouted after the new concrete placement has fully cured as directed in the Drawings. Concrete s pecified to be left in place that is damaged shall be repaired by ap proved means to the satisfaction of the Engineer. The E ngineer may from time to time direct the Contractor to make addi tional repairs to existing concrete. These repairs s hall be made as specified or by s uch other methods as may be appropriate.

The project, as currently planned , consists of replac ing the exist ing pump station discharge headers and access tunnel with a new concrete pipe gallery . A new op e n-t rench setup , housing the new piping , will incorporate a below-grade slab/mat foundation situated on the order of 10 feet below existing grade. A deep foundation system will also be necessary for select structures . In addition , two 36-inch high pressure lines will be replaced to the south and east of the pump house _ The project vicinity and boring locations are illustrated on Plate A. 1, Plan of Borings 1 .2 Purpose and Scope The purpose of this geotechnical engineering study has been to detennine the general subsurface condit ions , evaluate the engineering characteristics of the subsurface materials encountered , and develop recommendations for the type or types of foundat ions suitable for the project To accomplish its intended purposes, the study has been conducted in the following phases : (1) dri!!ing sample borings !o determine the ge nera! subsurface conditions and to obtain samples for te sting ; (2) performing laboratory tests on appropriate samples to determine pertinent engineering properties of the subsurface materials; and (3) performing engineering analyses , us ing the field and laboratory data to develop geotechnical recommendat ions for the proposed construction The design is currently in progress and the locations and/or elevations of the structure could change Once the final design is near completion (BO-percent to 90-percent stage), it is recommended that CMJ Engineering , Inc be retained to rev iew tho se portions of the construction documents pertaining to the geotechnical recommendat ions , as a means to determine that our recommendations have been interpreted as intended 1 .3 Report Format The text of the report is contained in Se ctions 1 through 11 All plates and large tables are contained in Appendix A _ The alpha -numeric plate and table numbers ident ify the appendix in which they appear Small tables of less than one page in length may appear in the body of the text and are numbered according to th e se ction in which they occur Report No 10 3-10-11 3 C MJ EN G I NEER ING . I N C Units used in the report are based on the English system and may include tons per square foot (tsf), kips (1 kip = 1,000 pounds). kips per square foot (ksf), pounds per square foot (psf), pounds per cubic foot (pcf), and pou nds per square inc h (psi) 2.0 FIELD EXPLORATION AND LABORATORY TESTING 2.1 Field Exploration Subsurface materials at the project site were explored by seven (7) vertical soil borings . The borings were drilled using hollow-stem or continuous flight augers at the approximate locations shown on the Plan of Borings , Plate A.1 . Boring B-2 was not drilled due to underground utility conflicts . The boring logs are included on Plates A.4 through A 10 and keys to classifications and symbols used on the logs are provided on Plates A2 and A 3. Undisturbed samples of cohesive soils were obtained with nominal 3-inch diameter thin-walled (Shelby) tube samplers at the locations shown on the logs of borings . The Shelby tube sampler consists of a thin -w alled steel tube with a sharp cutting edge connected to a head equipped with a ball valve threaded for rod connection . The tube is pushed into the soil by the hydraulic pulldown of the drilling rig . The soil specimens were extruded from the tube in the field, logged, tested for consistency with a hand penetrometer, sealed , and packaged to limit loss of moisture. The consistency of cohesive soil samples was evaluated in the field using a calibrated hand penetrometer. In this test a O 25-inch diameter piston is pushed into the relatively undisturbed sample at a constant rate to a depth of 025 inch The results of these tests, in tsf. are tabulated at respective sample depths on the logs When the capacity of the penetrometer is exceeded, the value is tabulated as 4 5+ To evaluate the relative dens it y and consistency of the harder formations, a modified version of the Texas Cone Penetration test was performed at selected locations Texas Department of Transportation (TxDOT) Test Method Tex-132-E specifies driving a 3-inch diameter cone with a 170-pound hammer freely falling 24 inches . This results in 340 foot-pounds of energy for each blow. This method was modified by utilizing a 140-pound hammer freely falling 30 inches This results in 350 foot-pounds of energy for each hammer blow In relatively soft materials, the penetrometer cone is driven 1 foot and the number of blows required for each 6 -inch penetration is tabulated at respected test depths . as blows per 6 inches on the log In hard materials (rock or Repo rt No 103-10-11 3 CMJ ENGlNEERING, l .'iC 2 rock-like), the penetrometer cone is driven with the resulting penetrations, in inches, recorded for the first and second 50 blows, a total of 100 blows The penetration for the total 100 blows is recorded at the respective test ing depths on the boring logs . Continuous, relatively undisturbed samples were obtained at selected intervals with a nominal 3-inch I D. barrel sampler which operates inside the hollow-stem augers during drilling . Continuous coring was performed at selected intervals in rock and rock-like materials using an tfvV (formerly NX) size , double-tube core barrel . This core barrel produces a nominal 2-inch diameter core sample . The core recovery and Rock Quality Designation (RQD) in percent are included in the appropriate column on the logs of borings The recovered percent is presented first for each core run and the RQD percent is presented immediately beside the recovered percent, in the adjacent column . Ground-water observations during and after completion of the borings are shown on the upper right of the boring log Upon completion of the borings, the boreholes were backfilled with soil cuttings , plugged by hand tamping, and capped with asphalt patching where applicable 2.2 Laboratory Testing Laboratory soil tests were performed on selected representative samples recovered from the borings In addition to the classification tests (liquid limits, plastic limits, and percent passing the No . 200 sieve), moisture content, unit weight , and unconfined compressive strength tests were performed Results of the laboratory classification tests, moisture content , unit weight, and unconfined compressive strength tests conducted for this project are included on the bor ing logs Three swell tests were performed on specimens from selected samples of the clays . These tests were performed to help in evaluating the swell potential of soils in the area of the proposed structures The results of the swell tests are presented on Plate A.11 The above laboratory tests were performed in general accordance with applicab le ASTM procedures, or generally accepted practice Repo rt No 10 3-10-11 3 CMJ ENG I N EE RING, l NC 3 3.0SUBSURFACE CONDITIONS 3.1 Site Geology According to the Dallas Sheet of the Geologic At la s of Texas , the project site is geologically located in the Al luv ia l Terrace deposits overly in g the soils and rock of the Fort Worth and Duck Creek (undiv ided) geological formation of the Lower Cretaceous Age . The alluvi a l and terrace deposits are generally a mixture of fine-grained and coarse materials, which are typically layered with grain sizes increasing with depth . At the surf ace the clay port ions of these deposits can be moderately to highly active . Groundwater is typically present in these deposits , especia lly in the proximity of a river or creek . The Fort Worth Limestone consists of limestone and clay, with the limestone portions typ ica lly being relatively hard . This formation typically weathers to form relatively shallow deposits of active clay soils . The Duck Creek Formation cons ists of limestone with some shaly portions This format ion typically weathers to form relatively deep active clay soils . 3.2 Soil Conditions Specific types and depths of subsurface strata encountered at the boring locations are shown on the boring logs i n Appendix A The genera lized subsurface stratigraphy encountered in the borings are discussed below . Note that depths on the borings refer to the depth from the ex isting grade or ground surface present at the time of the investigation, and the boundaries between the various soil types are approximate Aspha lt paveme.nt was encountered at the surface in Boring B-5 and was 5 inches in thickness . Borings B-1, B-3 , B-4, 8-6, and B-7 encountered approximately 2 to 10 feet of fill co nsi sti ng of clays, sandy clays and clays often containing grave l. Select portions of fill also cont ai ned br ick fragments, asphalt fragments, and sand Natural so ils encountered consisted of various dark brown, brown, light brown, reddish brown, light gray, gray, and dark gray sandy clays, silty clays , clayey sands, shaly clays, and clays . The clays are generally stiff to hard (soil basis) in cons istency with pocket penetrometer readings of 1 5 to over 4 5 tsf The various soils had tested Liquid Limits (LL) of 24 to 64 w ith Plasticity Indic es (Pl) of 6 to 42. and are class ified as SC , CL and CH by the uses T es ted dry unit we ig ht va lue s were 90 Report No 103-10-113 C MJ ENG INEFRING . I NC to 123 pcf and unconfined compressive strength test values were 1,120 to 10,000 psf Select strength tests reflect more granular materials or soils containing appreciable amounts of gravel . Gray shale was next present in Boring B-1 at 23 feet The gray shale contains limestone seams and is soft (rock basis), with a Texas Cone Penetration (THD) test value of 93 blows for 11 inches of penetrat io n Gray limestone was next encountered in Borings B-1, B-3, and B-4 at depths of 23 to 31 feet. Shale seams and layers up to 1 foot in thickness were present within the gray limesto ne A layer of gray shale was also present within the gray limestone in Boring B-4 from 26 feet to 32 fee t The gray limestone was hard (sedimentary rock bas is) with Texas Cone Penetrometer (THO) values of 1 to 11/.. inches per 100 blows . Rock qual ity designation (RO D) measurements of recovered core samples range from 14 to 42 percent, with an average RDQ value less than 50 percent, indicating poor to fair rock quality, or generally highly fractured in-situ rock Laboratory testing of gray limestone samples in unconfined compression testing resulted in strength values varying from 245,700 to 795,000 psf These values are considered moderate to high strength values from the viewpoint of rock strength . Unconfined compression testing of tl1e gray shale strata and layers was not possible due io their highly shaly and brittle structure The Atte rbe rg Limits tests indicate the clays encountered at this site are generally moderately active to highly active with respect to moisture induced volume changes Act ive clays can experience volume changes (expansion or contraction) with fluctuations in their moisture con tent. 3.3 Ground-Water Observations T he borings were drill ed using continuous hollow stem and continuous flight augers in order to observe ground-water seepage during drilling Ground-water seepage was encountered during drilling in Borings B-1, B-3 throu gh B-6 and B-8 at depths of 8 to 23 feet below existing grade Wet rotary drilling methods were util iz ed in Borings B-1, B-3, and 8-4 below depths of 25 to 35 feet Therefore, accurate water level readings were not possible in these borings Water levels of 10 to 18 feet were measured in Borings B-5, B-6, and B-8 at drilling completion Boring B-7 was dry during drilling and at completion of drilling operations .

A deep foundation system transferring column loads to a suitable bearing stratum is considered the most positive foundation system Deep foundations at this site may consist of straight drilled reinforced concrete shafts penetrating the gray limestone with shale seams and layers and/o r gray shale with lime ston e sea ms Consideration can be given to a mat foundation system for the pipe gallery open-t rench struc ture if movement can be tolerated and the slab is designed to tolerate potential movements due to moisture induced volume changes in the surficial soils without inducing unacceptable distress in the foundation or structural elements The key to the success of slab performance incl udes obtaining the proper design parameters for design, designing the slab for the representative movements anticipated, and construction and post-construction techniques to reduce the possibility of undue movements . Expansive soils will neither heave nor shrink unless the actual moisture content of the soil changes . Therefore, mainta ining as constant a moisture content aside and below slab foundations becomes of paramount importance to reduct ion of soi l movements Foundation recommendations for the various sections are provided in the follow ing sect ion s 4.2 Straight Shaft Design Parameters 4 .2 .1 De sign Criteria Recommendations and parameters for the design of cast-in-place straight-shaft drilled piers are outl ined below Specific recommendations for the construction a nd in stallation of the st ra igh t drilled piers a re included below, and shall be fol lowed during construction Bearing Stratum Unweathered gray LIMESTONE with shale seams AND/OR gray SHALE with limestone seams Depth of Be ar ing Stratum : Appro xima tely 23 to 31 feet below exist ing grades Required Penetration/Depth: All piers should penetrate into the bear ing stratum a minimum of 3 feet Deeper penetrations may be requ ired to develop addit ional s kin fri ction and/or uplift resistance Allowable End Bearing Capac ity: 20,000 psf Allow a ble Skin Friction: Appl icable below temporary casing; 1,800 psf for compre ssive loads and 1,000 psf for tensi le loa ds The gray sha le is variable in its presence ov e r this site The gray shale is significantly weake r than the gray limestone and therefore governs the design parameters R eport No 103 -10-11 3 C M) E:-I GINEER ING, ]'\IC 7 The maximum ratio of overall shaft length to shaft diameter is 20: 1 The above values contain a safety factor of three (3) Penetrations greater than the minimum penetration may be required to develop addit ional skin friction and/or uplift resistance For lateral shaft resistance , an allowable passive resi stance of 4 ,000 psf may be considered in the unweathered gray limestone and/or gray shale An allowable passive resistance of 1,000 psf may be considered in the overlying soils Lateral shaft resistance should not be considered within the upper 10 feet It should be anticipated that ground-water seepage above the bearing stratum will be encountered during installation of the straight shafts and temporary casing will be required for proper installation . In order to develop full load carrying capacity in skin friction, adjacent shafts should have a minimum center-to-center spacing of 3 times the diameter of the larger shaft . Closer spacing may require some reductions in skin friction and/or changes in installation sequences Closely spaced shafts should be examined on a case-by -case basis As a general guide, the design skin friction will vary linearly from the full value at a spacing of 3 diameters to 50 percent of the design value at 1.0 diameter We recommend a minimum pier diameter of i8 inches . Settlements for properly installed and constructed straight shafts in the gray limestone and/or gray shale will be primarily elastic and are estimated to be one inch or less with differential settlements of less than one-hatf an inch 4 .2 .2 Soil Induced Uplift Loads The drilled shafts could experience tens ile loads as a res ult of post construction heave in the site soils . The magnitude of these loads varies with the shaft diameter , soil parameters, and particu larly the in-situ moisture levels at the time of construction For design purposes , an uplift load of 1,500 psf over a shaft length of 10 feet is estimated This load must be resisted by the dead load on the shaft , continuous vertical reinforc ing steel in the shaft , and a shaft adhesion developed within the bearing strata In order to aid in the structural design of the reinforcement, minimum reinforcing should be equal to O 5 percent of the shaft area 4.2.3 Drifled Shaft Con struction Considerations Drilled p ie r construction should be monitored by a representative of the geotechnical engineer to observe , among other things , the following items : Report No 103-10-11 3 CMJ ENG !NEFRIN G . l NC 8 • Identification of bearing material • Adequate penetration of the shaft excavation into the bearing layer • The base and sides of the shaft excavation are clean of loose cuttings • If seepage is encountered, whether it is of sufficient amount to require the use of temporary steel casing If casing is needed it is important that the field representative observe that a high head of plastic concrete is maintained within the casing at all times during their extraction to prevent the inflow of water Precautions should be taken during the placement of re inforcing steel and concrete to prevent loose, excavated soil from falling into the excavation . Concrete should be placed as soon as practical after completion of the drilling, cleaning, and observation . Excavation for a drilled pier should be filled with concrete before the end of the workday , or sooner if required to prevent deterioration of the bearing material Prolonged exposure or inundation of the bearing surface with water will result in changes in strength and compressibility characteristics . If delays occur, the drilled pier excavation should be deepened as necessary and cleaned , in order to provide a fresh bearing surface. Excavations for the shafts should be maintained in the dry . It should be anticipated that ground- water seepage will be encountered during installation of the straight shafts and that seepage rates and/or caving will be sufficient to require the use of temporary casing for installation of the straight shafts The casing should be seated below the zone of seepage with all water and most loose material removed prior to beginning the design penetration Care must then be taken that a sufficient head of plastic concrete is maintained within the cas ing during extraction The concrete sh·ould have a slump of 6 inches plus or minus 1 inch The concrete should be placed in a manner to prevent the concrete from striking the reinforcing cage or the sides of the excavation . Concrete should be tremied to the bottom of the excavation to control the maximum free fall of the plastic concrete to less than 10 feet , or focus concrete in the middle of the reinforcing cage to prevent segregation A drilling rig of sufficient size and weight will be necessary for drill ing and/or coring through the hard layers to reach the desired bearing stratum and achieve the requ ired penetration . In addition to the above guidelines , the specifications from the A ssocia tion of Drilled Shaft Contractors Inc "Standards and Specifications for the Foundation Drilling Indu stry " as Revised 1999 or other Report N o . 103-10-113 C MJ ENGINHRING . lN C. 9 recognized spec ific ati ons for proper install at ion of drilled shaft foundation systems should be followed . 4 .2.4 Grade Beams In conjunction with a drilled shaft foundation system , grade beams should be supported by the drilled shafts . A min imum 8-inch void space should be provided beneath all grade beams to prevent contact w ith the swell ing clay soils This void w ill serve to minimize distress resulting from swell pressures generated by the clays . Grade beams may be cast on cardboard carton forms or formed above grade If cardboard carton forms are used, care should be taken to not crush the carton forms, or allow the carton forms to become wet prior to or during concrete placement operations A soil retainer or trapezoidal void forms should be provided to help prevent in-filling of this void . Backfill against the exterior face of grade beams or panels should be properly compacted on-site clays Compaction should be a minimum of 93 percent of ASTM D 698, at a minimum of 2 percentage points above the opt imum moisture content detenmined by that test. This clay f ill is intended to reduce s urface water infi ltration beneath the structures 4 .3 Stiffened and Thickened Slab-On-Grade (Pipe Gallery) 4 .3.1 Design Con siderations and Potential Movements A s tiffened monol it h ica lly pl aced s lab -on-grade foundation used at this site must be designed to tolerate potential movem ents due to moisture induced volume changes in the soils expected to be encountered at fin ished grade Finished grade for the pipe gallery structure is understood to be on the order of 1 O feet below existing grade or greater Cons ideration should be given to the installation of pressure rel ief valves or drains to prevent the structure from "floating" due to perched wa ter W ater s hould be modeled at ground level for buoyancy considerations The foundation should be designed by a structural engineer familiar with stiffened mats subject to diffe rential movement Foundation movements are ant icipated due to post construct ion heave of th e underlying so ils or as a res ult of settlement A monolithic, slab on-grade will be subject to movement as a resu lt of moisture induced volume changes in the moderately active to highly ac tive cla y s The clay s ex pa nd (hea ve) with increases i n mois ture and contract (sh ri nk) with Repo r1 No 103-10-113 C MJ ENG l :-IHR I NG, }NC 10 decreases in moisture . The move ment typ ically occurs as post construction heave The potential magn itude of the moi sture induced mov ements is rather indeterminate It is influenced by the soil properties. overburden pressures, and to a great ext ent by soil moisture levels at the time of construction The greatest potential for post -construc ti on movement occurs when the soils are in a dry condition at the time of construction . Based on the conditions encountered in the borings, potential moisture induc ed movements for slabs s ituated ne ar present existing grade are estimated to be on the order of 3 inches for soils in a dry cond ition with no structure load applied . Moisture induced movements for slabs situated approximately 10 feet below existing grade are estimated to be on the order of 1~ inches . ~ Design Criteria Design parameters are presented below in Table 4 3 2 .1 for Potential Vertical Rise (PVR) for slabs situated on the order of 10 feet below existing grade The PVR values presented below are for two different conditions: 1) pad site with no subgrade preparation with dry moisture condit ions; 2) a pad with subgrade preparation consisting of a minimum of 1 foot of non-expansive select fill over a minimum of 2 fe et of mo isture conditioned soils as described below in Section 4 .3 3 Moisture conditioning is recommended to be achieved by mechanically reworking the clays The use of these methods will not el imin ate th e risk of unacceptab le movements TABLE 4.3.2-1 -SLAB DESIGN PARAMETERS Subgrade Preparation PVR (in.)

A modulus of subgrade rea c tio n of 75 pci is appropr iate for a mat foundation situa ted on native so ils w ith no subgrade preparation A modulus of subgrade reaction of 100 pci is appropriate for a mat foundation supported by a minimum of 1 foot of non-ex pansive select fill The a bove de sign v a lu es conta in a factor of safety of thr ee (3) Re po rt No 103-10 -113 C MJ E~GfNHR ING, I NC 1; If slab stiffness is not sufficient to res ist the ground movements, these movements can cause cracking of the slab and differential movements The PVR values presented above are applicable only when s ite moisture conditions are controlled by the climate alone on a well graded site (ie no imprope r drainage , water leaks or free water sources) Under these conditions, moisture increases within the supporting soils and the resulting differential foundation movements are much lower than differential movements that can occur due to post-construction movements due to localized saturat ion caused by free water sources near or beneath the structures . Such movements from these unusual sources can result in greater differential movements than the slab was designed to tolerate . Soil movements, significantly larger than estimated, could occur due to inadequate site grading, poor drainage, ponding of rainfall, and/or leaking pipelines The performance of a slab foundation can be significantly influenced by landscaping maintenance, recessed landscaping additions near the structure; water line leaks, any other free water sources, and deep-rooted trees and shrubs . For example, should leaks develop in underground water or sewer lines or the grades around the structure are changed and cause ponding of water, unacceptable slab movements could develop A greater risk of unsatisfactory foundation performance exists with a slab-on-grade design than for a drilled shaft design extending below the zone of seasonal mo isture change The ke y to the success of this foundation is proper design/construction . and providing control of the below-slab water. Providing excellent drainage away from the structure, preventing ponding water aside the structure, and using relatively impermeable backfill to prevent water intru s ion v ia utility line backf ill enhance the slab performance 4 .3 .3 Mechanical Re working of Near-Surface Clays with 1 ' Select Fill Cap In general. the procedure is performed as follows: 1 . Remove all existing pavements, surface vegetat ion , trees and associated root mats, organic topsoil and any other deleterious material . 2 Excavate surficial clays to a minimum of 2 .5 ieet below finished subgrade eievation. Scarify the exposed clay subgrade at the base of the excavation, to a depth of 8 inches, adjust the moisture, and compact at a minimum of 2 percentage points above optimum moisture to between 93 and 98 percent of Standard Proctor density (ASTM D 698) Over-compaction should not be allowed 3 Fill pad to 1 foot below finished subgrade elevation using site excavated or similar clay soils Compact in maximum 9-inch loose li fts at a min imum of 2 percentage points above optimum moisture to between 93 and 98 percent of St andard Proctor density (ASTM D 698) Over- compaction shou ld not be allowed R eport N o 103-10-113 CMJ ENGINEERING. ]NC 1 2 4 . Complete pad fill using a minimum of 1 foot of sandy clay/clayey sand , non-expansive select fill with a Liquid Limit less than 35 and a Plasticity Index (Pl) between 4 and 16. The select fill should be compacted in maximum 9-inch loose lifts at -2 to +3 percentage points of the soil's optimum moisture content at a minimum of 95 percent of Standard Proctor density (ASTM D 698) The select fill should be placed within 48 hours of completing the installation of the moisture conditioned soils. Any crushed stone/rock used to replace the select fill must meet the requirements of TxDOT Item 247 , Type A, Grades 1 or 2 5.0EXPANSIVE SOIL CONSIDERATIONS 5.1 Site Drainage An important feature of the project is to provide positive drainage away from the proposed structures If water is permitted to stand next to or below the structure, excessive soil movements (heave) can occur. This could result in differential floor slab or foundation movement. A well-designed site drainage plan is of utmost importance and surface drainage should be provided during construction and maintained throughout the life of the structure . Consideration should be given to the design and location of gutter downspouts, planting areas , or other features which would produce moisture concentration adjacent to or beneath the structure or paving Consideration should be given to the use of self-contained, watertight planters Joints next to the structure should be sealed with a flexible joint sealer to prevent infiltration of surface water Proper maintenance should include periodic inspection for open joints and cracks and resealing as necessary. Rainwater collected by the gutter system should be transported by pipe to a storm drain or to a paved area If ~ownspouts discharge next to the structure onto flatwork or paved areas , the area should be watertight in order to eliminate infiltration next to the buildings. 5.2 Additional Design Considerations The following information has been assimilated after examination of numerous projects constructed in active soils throughout the area It is presented here for your convenience If these features are incorporated in the overall design of the project, the performance of the structures should be improved • Special consideration should be given to complet ion items outsid e th e build ing areas . such as stairs , sidewalks, signs , etc They should be adequately designed to susta in the potential vertical movements mentioned in the report Re p o rt No 103-10-11 3 C MJ E~C l"NEER l"NG l NC 13 • Roof drainage should be collected by a system of gutters and downspouts and transmitted away from the structures where the water can drain away without entering the building subgrade • Sidewalks should not be structurally connected to any buildings . They should be sloped away from the buildings so t hat water will drain away from the structures. • The paving and the general ground surface should be sloped away from the buildings on all sides so that water will always drain away from the structures Water should not be allowed to pond near the buildin gs after a slab has been placed . • Every attempt should be made to limit the extreme wetting or drying of the subsurface soils since swelling and shrinkage will result. Standard construction practices of providing good surface water drainage should be used A positive slope of the ground away from foundations should be provided to carry off the run -off water both during and after construction. • Backfill for utility lines or along the perimeter beams should consist of on -site material so that they will be stable . If the backfill is too dense or too dry, swelling may form a mound along the ditch line . If the backfill is too loose or too wet , settlement may form a sink along the ditch line . Either case is undesirable since several inches of movement is possible and floor cracks are likely to result The soils should be processed using the previously discussed compaction criteria . 6.0 RETAINING WALL RECOMMENDATIONS 6 .1 Permanent Retaining Walls 6.1 .1 General Retaining walls associated with the pipe gallery are anticipated to be double formed The type of construction affects the lateral earth pressures acting on the retaining walls . Design parameters are provided below for double formed walls The retaining walls are assumed to be incorporated into the associated structure and will be supported by the previously recommended foundation systems , as appropriate 6.1 .2 Double Formed Wall Recommended lateral earth pressures, expressed as equivalent fluid pressures . are presented below for a rigid double formed wall w ith a dra i ned condition and a leve l backfill behind the top of the wall. The equivalent fluid pressure for an undrained condition should be used if a drainage system is not present to rem ove water trapped in the backfill and behind the wall and for the pipe gallery structure Pressures are provid ed for an at-rest and active earth pressure conditions In Repo rt No 103-10-11 3 CMJ F.NC l.'J EE RJN C I NC 14 order to allow for an active condition the top of the wall(s) must deflect on the order of 04 percent. Active earth pressures are not considered appropriate for rigid structure walls, particularly those assoc iated with the building For the select fill or free draining granular backfill these values assume that a "full " wedge of the material is present behind the wall The wedge is defined where the wall backfill limits extend outward at least 2 feet from the base of the wall and then upward on a 1 H:2V slope For narrower backfill widths of granular or select fill soils , the equivalent fluid pressures for the on-site soils should be used Surcharge loads must be included in the wall design where appropriate, as previously discussed . Piping and electrical conduits through the fill should be designed for potential soil loading due to fill settlement TABLE 6.1.2-1 -EQUIVALENT FLUID PRESSURES At-Rest Equivalent Active Equivalent Passive Equivalent Backfill Material Fluid Pressure (pcf) Fluid Pressure (pct) Fluid Pressure (pct) Drained Undrained Drained Undrained Drained Undrained Excavated on-site clay 100 110 85 100 175 150 or clay fill materi al Sel ect fill or on -site soils meeting material 65 90 50 85 300 210 specifications Free draining granular 50 90 35 80 500 330 wall backfill material Granular Wall Backfill : All free draining granular wall backfill material should be a crushed stone, sand/gravel mixture, or sand/crushed stone mixture The material should have less than 3 percent passing the No . 200 sieve and less than 30 percent passing the No 40 sieve . The minus No 40 sieve material should be non-plastic Granular wall backfill should not be water jetted during installation Select Fill Behind Walls: All wall select backfill should consist of clayey sand and/or sandy clay material with a plasticity index of 16 or less, with a liquid limit not exceeding 35 The select fill should be placed in maximum eight inch lifts and compacted to between 95 and 100 percent of Standard Proctor density (ASTM D 698) within a moisture range of -3 to +3 percentage points of Repo rt No 103-10-113 CMJ E NG IN EE RfNG 1 NC 15 the optimum moisture Compaction within five feet of the walls should be accomplished using hand compaction equipment and should be compacted between 90 and 95 percent of the Standard Proctor Density On -Site Soil Backfill : For wall backfill areas with site-excavated materials, or sim ilar imported materials all oversized fragments larger than four inches in maximum dimension should be removed from the backfill materials prior to placement. The backfill should be free of all organic and deleterious materials, and should be placed in maximum 8 inch compacted lifts at a minimum of 95 percent of Standard Proctor density (ASTM D 698) within a moisture range of plus to minus three (3) percent of optimum moisture Compaction within five feet of the walls should be accomplished using hand compaction equipment, and should be between 90 and 95 percent of the Standard Proctor Density 6.2 Wall Backfill Settlement Settlement of the wall backfill should be anticipated . Piping and conduits through the fill should be designed for potential soil loading due to fill settlement. Floor slabs, sidewalls, and pavements over fills may also settle Backfill compacted to the density recommended above is anticipated to settle on the order of O 2 to 0.5 percent of the fill thickness . 6.3 Wall Drainage Drained conditions must incorporate drainage behind the retaining wall to prevent the development of hydrostatic pressures For double formed walls a perimeter drain should be prov ided . The bottom of the drain should be situated a minimum of 12 inches lower than the adjacent below grade floor slab The perimeter drain should be a perforated or slotted drain with a minimum pipe diameter of 4 inches and be wrapped in filter fabric for protection against infiltration Accessible clean-outs should be provided 7.0 OPEN CUT, SLOPED AND BRACED EXCAVATIONS 7.1 General The overburden soils can be excavated by conventional methods including the use of large backhoes , bulldozers. track or wheel loaders and scrappers. Groundwater could be encountered Report No 103-10-11 3 C MJ EN G JN H RI N G. l NC 16 in the overburden soils, particu l arly if construction proceeds during wet periods of the year. This water can generally be handled during construction by perimeter ditches and pumping Exposed subgrades will deteriorate rapidly due to both dry ing and wetting conditions Ramps in the clay soils will become slick during w et weather and affec t rub ber tired equipment 7.2 Open Cut The soils present in the excavation are subj ect to caving and sloughing and must be sloped or braced in the interest of safety If sufficient space is ava ilable to provide a stable slope , an open cut can be used . For excavations less than 5 feet into predom i nately clayey soils, walls may be cut near vertical in accordance with OSHA regulations All other excavations at this site will require sloped sidewalls, temporary bracing , or trench shields in accordance with OSHA regulations , in order to prevent sidewall and/or slope sloughing . Excavated soils should not be stockpiled and/or existing structures should not be within 3 feet or one-ha lf the depth of the excavation , whichever is greater, from the edge of the excavation 7.3 Retained Cut Temporary retention syst em s could be required due to proximity of the existing structures and paving and where there is insufficient clearance to lay back the slopes . Various types of retention systems can be considered. Typ ically , the most app li cab le systems are cantilevered shafts or soldier piles with wood lagging These are usuall y designed and construct e d by sp ecial ty contractors . 8.0 SEISMIC CONSIDERATIONS Based on the conditions encountered in the borings for the above referenced project the IBC-2006 site classification is TYPE C for seism ic evaluation . 9.0 EARTHWORK 9.1 Site Preparation The subgrade should be firm and able to support the construc ti on equ ipment without displacement Soft or yielding subgrade should be corrected and made stable before construction proceeds The Report No 103-10-11 3 CM) EN C IN H RI NC, I NC 1 7 subgrade should be proof rolled to detect soft spots , which if exist, should be excavated to provide a firm and otherwise su itable subgrade Proof rolling should be performed using a heavy pneumatic tired roller , loaded dump truck , or sim ilar piece of equipment The proof rolling operations should be observed by the project geotechnical engineer or his/her representat ive 9.2 Placement and Compaction Fill material should be placed in loose lifts not exceeding 8 inches in uncompacted thickness . The uncompacted lift thickness should be reduced to 4 inches for structure backfill zones requiring hand-operated power compactors or small self-propelled compactors . The fill material should be uniform with respect to material type and moisture content. Clods and chunks of material should be broken down and the fill material mixed by disking, blading, or plowing, as necessary , so that a material of uniform moisture and density is obtained for each lift. Water required for sprinkling to bring the fill material to the proper moisture content should be applied evenly through each layer The on -site soils are suitable for use in site grading . Imported fill material should be clean soil with a Liquid Limit less than 55 and no rock greater than 4 inches in maximum dimension The fill materials should be free of vegetation and debris . The fill material should be compacted to a density ranging from 95 to 100 percent of maximum dry density as determined by ASTM D 698, Standard Proctor. In conjunction with the compacting operation . the fill material should be brought to the proper moisture content. The moisture content for general earth fill should range from 2 percentage points below optimum to 5 percentage points above optimum (-2 to +5). These ranges of moisture contents are given as maximum recommended ranges For some soils and under some conditions, the contractor may have to maintain a more narrow range of moisture content (within the recommended range) in order to consistently achieve the recommended density . Field density tests should be taken as each lift of fill material is placed As a guide . one field density test per lift for each 5,000 square feet of compacted area is recommended For small areas or critical areas the frequency of testing may need to be increased to one test per 2,500 square feet A minimum of 2 tests per lift should be requ ired . The earthwork operations should be observed and tested on a continuing basis by an experienced geotechnician working in conjunction with the project geotechnical engineer Report No 103-10-1 13 C MJ ENGlNHRJNC N C 18 Each lift should be compact ed , tested , and approved before another li ft is add ed . The purpose of t he field density tests is to provide some indication that un iform and adequate compaction is being obtained The actual q ua lity of the fill , as compacted, should be the respons ibi lity of th e con t ractor and satisfactory results from the tests should not be considered as a guarantee of the qual ity of the contractor's fi llin g operations 9.3 Trench Backfill Trench backfill for pipelines or other util ities should be properly placed and compacted Overly dense or dry backfill can swell and create a mound along the completed trench line Loose or wet backfill can settle and form a depress ion along the completed trench line D istress to overlying structures , pavements, etc . is likely if heaving or settlement occurs. On -site soil fill material is recommended for trench backfill. Care should be taken not to use free draining granular material , to prevent the backfilled trench from becoming a french drain and piping surface or subsurface water beneath structures, pipelines, or pavements . If a higher class bedding materia l is required for the pipel ines . a lean concrete bedding will limit water intrusion into the trench and will not require compaction after placement The soil backfill should be placed in approx imately 4-to 6- inch loose lifts The density and moisture content should be as recommended for fill in Section 92, Placement and Compaction, of this report A minimum of one field density test should be taken per lift for each 150 linear fe et of trench, with a m inimum of 2 tests per lift . 9.4 Excavation The side slopes of excavations through the overburden soils should be made in such a manner to provide for their stability during construction, as discussed in Section 7 .0 . Existing structures, pipelin es or other f aci lities, which are co nstructed prior to or during the currently proposed construction and which requi re excavation, should be protected from loss of end bearing or lateral support Temporary construction slopes and/or permanent embankment slopes should be prntected from surface ru noff water. Site grading should be designed to allow drainage at planned areas where e rosion protection is provided, instead of allowing surface water to flow down unprot ec ted slopes Permanent slopes at th e site should be as flat as practical to reduce creep and occurre nce of shallow sl ides Th e following slope angles are r ecomm e nd e d as maximums . Report No 103-10-113 CMJ EN C JNHRJNG, I NC 19 TABLE 9.4-1 Maximum Slope Angles Height (ft.) Horizontal to Vertical 0-3 1 1 3-6 2:1 6 -9 3 1 >9 4 :1 The above angles refer to the total height of a slope Site improvement should be maintained away from the top of the slope to reduce the possibility of damage due to creep or shallow slides. Trench safety recommendations are beyond the scope of this report The contractor must comply w ith all applicable safety regulations concerning trench safety and excavations including , but not limited to , OSHA regulations . 9.5 Acceptance of Imported Fill Any soil imported from off-site sources should be tested for compl iance w ith the recommendations for the particular application and approved by the project geotechnical engineer prior to the materials being used . The owner should also require the contractor to obtain a written , notarized certification from the landowner of each proposed off-site soil borrow source stating that to the best of the landowner's knowledge and belief there has never been contamination of the borrow source site w ith hazardous or toxic materials The certification should be furnished to the owner prior to proceeding to furnish soils to the site . Soil materials derived from the excavation of underground petroleum storage tanks should not be used as fill on this project 9.6 Soil Corrosion Potential Based upon past experience on other projects in the vicinity, soil resistivity and pH levels in so ils encountered at this site are potentially corrosive to steel or cast iron piping . Standard construction practices for protecting metal pipe and simiiar facil ities in contact with these soils should be used Concentrations of sulfates generally do not occur in sufficient concentrations in this area to indicate potential damage to Type I Portland cement concrete piping .

In the analysis, the geotechnical eng ineer must assume the subsurface conditions are similar to the conditions encountered in the borings .. However, quite often during construction anomalies in the subsurface conditions are revealed Therefore, it is recommended that CMJ Engineering , Inc be retained to observe earthwork and foundation installation and perform materials evaluation during the construction phase of the project . This enables the geotechnical engineer to stay abreast of the project and to be readily available to evaluate unanticipated conditions, to conduct additional tests if required and, when necessary , to recommend alternative solutions to unanticipated cond itions . Until these construction phase services are performed by the project geotechnical engineer, the recommendations contained in this report on such items as final foundation bearing elevations , proper soil moisture condition , and other such subsurface related recommendations should be considered as pre liminary It is proposed that construction phase observation and materials testing commence by the project geotechnical engineer at the outset of the project Experience has shown that .the most suitable method for procuring these services is for the owner or the owner's design engineers to contract directly w ith the project geotechnical engineer. This results in a clear, direct line of communication between the owner and the owner's design engineers and the geotechnica l engineer. 11.0 REPORT CLOSURE The boring logs shown in this report contain information related to the types of soil encountered at specific locations and times and show lines delineating the interface between these materials . The logs also contain our field representative's interpretation of conditions that are believed to exist in those depth intervals between the actual samples taken Therefore , these boring logs contain both Report No 10 3 -10-1 13 CM) ENGIN EE R ING, ]NC 2 1 factual and interpret ive information. La boratory soil class ifica ti on tests were also perform ed on samples from selected depths in the borings . The results of th ese tests, along with visual-ma n ual procedures were used to g e n e rally cl assify ea ch strat um Therefore , it should be understood t hat the classification data on the logs of bori ngs represent visual estimates of classificat ions for those portions of each stratum on w hic h t h e full ra nge of laboratory soil classification tests were not performed It is not implied th at th es e logs are representative of subsurface conditions at ot he r locations and t imes. With regard to ground-water conditions , this report presents data on ground-water levels as they were observed during the course of the field work In particular, water level readings have been made in the borings at the times and under conditions stated in the text of the report and on the boring logs It should be noted that fluctuations in the level of the ground-water table can occur with passage of time due to variations in rainfall, temperature and other factors Also, this report does not include quantitative information on rates of flow of ground water into excavations, on pumping capacities necessary to dewater the excavations , or on methods of dewatering excavations Unanticipated soil conditions at a construction site are commonly encountered and cannot be fully predicted by mere so il samples, test borings or test pits Such unexpected conditions frequently require that add itional expenditures be made by the owner to attain a properly designed and constructed proj ect. T herefore, prov ision for some contingency fund is recommended to accommod ate such potential extra cost The a nalyses , conclus ions and recommendations contained in this report are based on site condit ions as they existed at the tim e of our field investig ation and further on the assumption that the exploratory borings are representative of the subsurface conditions throughout the site ; that is, the subsurface conditions everywhere are not s ign ificantly different from those disclosed by the borings at the time they were complet e d If, during construction, different subsurface conditions from those encountered in our borings are observed, or appear to be present in excavations, we must be advised promptly so that w e can review t he se co ndit ions and reconsider our recom mendations where necessary If there is a substantia l lapse of time between submission of this report and the start of the work at the site, if cond itions have changed due either to natural causes or to construction operations at or adjacent to the s ite , or if structure locations , structural loads or finish grades are chang ed, we urge that we be promptly informed and retained to review our report to determine the applicability of the conclusions and recommend at ions , considering th e chang ed conditions and/or time lapse Report No 103-10-11 3 C M J EN GINEER!NG, I NC 22 Further, it is urged that CMJ Engineering , Inc. be retained to review those portions of the plans and specifications for this particular project th a t pertain to earthwork and foundations as a means to determine whether the plans and specifications are cons istent w it h the recommendations contained in this report . In add ition , we are available to observe construction, particularly the compaction of structural fill , or backfill and the construction of foundations as recommended in the report, and such other field observations as might be necessary The scope of our services d id not include any environmental assessment or investigation for the presence or absence of wetlands or hazardous or toxic materials in the soil , surface water, ground water or air, on or below or around the s ite . This report has been prepared for use in developing an overall design concept Paragraphs, statements, test results , boring logs, diagrams , etc should not be taken out of context , nor utilized without a knowledge and awareness of their intent within the overall concept of this report The reproduction of this report, or any part thereof, supplied to persons other than the owner, should indicate that this study was made for d e sign purposes only and that verification of the subsurface conditions for purposes of determining difficulty of excavation, trafficability , etc are responsibilities of the contractor This report has been prepared for the exclusive use of Kimley-Horn and Associates , Inc for specific application to design of this project. The only warranty made by us in connection w ith the services provided is that we have used that degree of care and skill ordinarily exercis ed under similar conditions by reputable members of our profession practicing in the same or s imilar locality. No other warranty , expressed or implied , is made or intended .

Four (4) soil samples collected by CMJ Engineering perso nnel at va rious locations within the pump station were tested in the laboratory for moisture content, pH, chloride ion concentration, sulfide ion concentration, conductivity and resistivity. Laboratory test results are tabulated in Appendix A. With respect to the chemical properties of the so il , the test re s ults of the samples indicate : • Moisture content from 18 .0% to 25.0%. • ApHfrom7.8to8 .l. • Chloride ion concentration of 2 to 18 ppm . • No detectable s ulfide ions. • Conductivities from 290 to 1,3 00 microhmo s. • Resistivities from 760 to 2,900 ohm-cm. Considering each of the chemical and electrical soi l properties that are te s ted in the fie ld and the laboratory, general guidelines for interpreting the re s ult s are as follows: • Soil Moisture -The higher the soi l moi s ture content , the g re a ter the anticipated rate of corrosion. Moi s ture contents can range from I % (very dry sands) to 40% (clays holding a great deal of moisture). Typical values are I 0 to 15% with over 20% moi sture considered hi g h. • pH -Acidic soi ls and groundwater are more co nducive to galvanic corrosion of ferrous material s than alkaline so ils and groundwater. • Conductivity -For a given corrosion cell with a fixed potential difference between the anode and cathode, the hi g her the conductivity , the g re a ter the metal lo ss. Conductivities over 350 microhmo s/cm (equivalent to a resi s tivity of 2850 o hm-cm ) are considered hi g h . 3.2 • S ulfid e Con cent ra ti o n -A ny d e t ec t a ble c o n ce ntrati o n s o f s ulfide io n s a re in d icati ve o f a n aerobic conditi o n s th a t m a y s uppo rt hi g h r at es of m e t a l di sso luti o n du e to mi cro bi o logica ll y influ e nc e d corros io n . • C hl o rid e Concent ra ti o n s -C hl o ri de io n s a re c a th o d e d e p o la ri ze rs, w hi c h e nh a nc e the rate o f co rr os io n .
