Contractor enters this Contract solely because of the results of such examination and not because of any representations pertaining to the Improvements or the completion thereof made to Contractor by Owner or any agent of Owner and not contained in this Contract. Owner agrees that subsurface or other presently unknown conditions may be encountered during performance of the Work which may result in extension of time for completion and increase in compensation due Contractor. Contractor agrees to notify Owner promptly in writing upon encountering any such condition. Contractor will advise Owner in writing of the extent of the time delays and provide revised schedules of anticipated completion dates. ARTICLE 7 – TESTING, INSPECTIONS AND CORRECTION OF WORK 7.1 Should the Owner, the Contract Documents, or any law, ordinance, or Governing Public Authority require that any portion of the Work be tested or inspected, Contractor shall give notice to Owner (or Governing Public Authority if the Governing Public Authority is the inspecting body) when such portion is ready for such testing, inspection, or approval, or, if the testing, inspection or approval is to be made or given by a person other than Owner, of the time, place, and date when such testing, inspection or approval is to be made or given.

If payments then or thereafter due to Contractor are not sufficient to cover such amounts, 12 S:\projects\611\12\05\3.0 Construction\3.1 Contracts and Specifications\3.1.1 Contracts\Paving Contract\Contract Book\Liberty Trails Phase 5 Paving_Contract Book - To Be Signed By Contractor.doc Contractor shall pay the difference to Owner. Contractor shall be required to pay such difference immediately upon written demand by Owner. ARTICLE 8 – CHANGES IN WORK 8.1 Without invalidating this Contract and without notice to any surety or sureties on any bond or bonds required by Contractor, Owner may order modifications in the Work or may order additional work not shown in the Contract Documents to be performed by Contractor and such modifications or additional work may entitle Contractor to extra compensation. Such modifications or extra work shall be authorized by a written Change Order, signed by Owner, such written Change Order to be executed prior to such modifications or extra work being commenced. 8.2 If modifications in the Work or additional work not shown on the Contract Documents are authorized pursuant to Paragraph 8.1 above, such additional work or modification shall be performed by Contractor and the cost thereof added to the Contract Price and paid by Owner upon completion of such additional work or modification. ARTICLE 9 – TIME FOR COMPLETION: EXTENSIONS OF TIME 9.1 Owner shall give Contractor written notice to proceed and Contractor shall complete the work in the number of working days specified on the Exhibit D of the Contract. Contractor shall provide Owner a schedule prior to commencing work. Contractor shall commence work on the Improvements in accordance with schedule and shall, unless delayed by one of the causes stated in Paragraph 9.4, below, and documented as mentioned in Paragraph 9.5 below, work diligently and substantially continuously until completion of the Improvements. 9.2 A working day is defined as a calendar day not including Saturdays, Sundays, or those legal non-days as specified in the list prepared by the Owner for contract purposes, in which weather or conditions not under the control of the Contractor shall permit the performance of the principal units of work underway for a continuous period of not less than seven (7) hours between 7:00 a.m. and 6:00 p.m. A principal unit of work shall be that unit which controls the completion time of the Contract. Nothing in this definition shall be construed as prohibiting the Contractor from working on Saturdays if he so desires and permission of the Governing Public Agency has been granted. If Saturday or Sunday work is permitted, working time shall be charged on the same basis as weekdays. Where the working time is expressed as calendar days or a specific date, the concept of working days shall no longer be relevant to the contract. 9.3 Substantial Completion date shall be defined in this contract and/or any of its accompanying exhibits as the stage in the progress of the Work when the Work or designated portion thereof is sufficiently complete in accordance with the Contract Documents so that the Owner can occupy or utilize the Work for its intended use. 13 S:\projects\611\12\05\3.0 Construction\3.1 Contracts and Specifications\3.1.1 Contracts\Paving Contract\Contract Book\Liberty Trails Phase 5 Paving_Contract Book - To Be Signed By Contractor.doc 9.4 Either party, Contractor or Owner, may be excused for delays in the performance of this Contract caused by any intentional acts or gross neglect of the other, by any acts of any public enemy, by any acts of any governmental agency, by war or war defense conditions, by fires, by unusual delays in transportation, by labor disputes, or by any other cause resulting in delay of the Work which is beyond such party’s reasonable control. Each party shall use due diligence to avoid any such delay or default and to resume performance under this Contract as promptly as possible after any such delay. 9.5 The completion date may only be changed for a delay of one of the causes mentioned in Paragraph 9.4. Any claim for an extension in the completion date by Contractor shall be based on written notice and supporting data delivered to Owner within thirty (30) days of the occurrence of the delaying event giving rise to the claim. Owner may allow Contractor an additional period of time to ascertain and collect more accurate data; however, all claims for adjustment of the Completion Date shall be determined by Owner. 9.6 The completion date will be extended in an amount equal to time lost due to delays beyond the control of Contractor, if a claim is made therefore and approved by Owner, as provided in Paragraph 9.5, which approval will not be unreasonably withheld or delayed. 9.7 Liquidated Damages for Failure to Complete on Time: The time of completion is the essence of this Contract. For each calendar day that any work shall remain uncompleted after the time specified in the Proposal and the Contract, or the increased time granted by the Owner, or as equitably increased by additional work or materials ordered after the Contract is signed, the sum per day given in the following schedule, unless otherwise specified in the Special Conditions, shall be deducted from the monies due the Contractor. Amount of Contract ($) Amount of Liquidated Damages ($) Less than 5,000.00 60.00 Per Day 5,000.00 to 14,999.99 80.00 Per Day 15,000.00 to 24,999.99 100.00 Per Day 25,000.00 to 49,999.99 120.00 Per Day 50,000.00 to 99,999.99 250.00 Per Day 100,000.00 250,000.00 500,000.00 to to to 249,999.99 499,999.99 999,999.99 500.00 750.00 1,000.00 Per Day Per Day Per Day More than 1,000,000.00 1,250.00 Per Day 14 S:\projects\611\12\05\3.0 Construction\3.1 Contracts and Specifications\3.1.1 Contracts\Paving Contract\Contract Book\Liberty Trails Phase 5 Paving_Contract Book - To Be Signed By Contractor.doc The sum of money thus deducted for such delay, failure, or non-completion is not to be considered as a penalty, but shall be deemed, taken, and treated as reasonable liquidated damages, per calendar day that the Contractor shall be in default after the time stipulated on the Contract for completing the Work. The said amounts are fixed and agreed upon by and between Owner and Contractor because of the impracticability and extreme difficulty of fixing and ascertaining the actual damages the Owner in such event would sustain; and said amounts are agreed to be the amount of damages which the Owner would sustain and which shall be retained from the monies due, or that may become due, the Contractor under this contract; and if said monies be insufficient to cover the amount owing, then the Contractor or his surety shall pay any additional amounts due. ARTICLE 10 – USE OF LAND BY OWNER 10.1 During construction of Improvements, Owner shall have the right to use such portion(s) of the Premises as may from time to time be deemed safe for such use by the Construction Manager. The use by Owner of any such portion(s) of the Premises shall not (i) constitute an acceptance by Owner of any Improvements which may have been constructed on such portion of the Premises by Contractor, (ii) affect in any way the dates and times when payments become due to Contractor from Owner under this Contract, or (iii) prejudice Owner’s rights under this Contract. The Improvements shall be deemed completed only when all Work under this Contract has been fully performed and a notice of completion of the Improvements has been duly accepted in writing by Owner and Governing Public Authority which acceptance will not be unreasonably withheld or delayed. ARTICLE 11 – TRAFFIC CONTROL AND CLEAN UP 11.1 Whenever the performance of the Work under this Contract creates a condition which could be hazardous to the public, Contractor shall take all necessary precautions and provide adequate means to protect those who must pass through, over, or adjacent to the Work. Contractor will notice Owner in writing of such risk. 11.2 During the performance of this Contract, Contractor shall keep all property adjacent to the Premises free of all accumulated rubbish and waste materials caused by Contractor’s operations in performing this Contract. On completion of the Improvements, Contractor promptly shall remove all such rubbish and waste materials, structures and all equipment used by it in performing this Contract from the Premises and adjacent property. If the Contractor fails to maintain and clean the Premises, the Owner may use the procedure provided in Paragraph 7.3 and the cost shall be charged against the Contractor. ARTICLE 12 – SUBCONTRACTORS 12.1 Before subcontracting any portion of the Work, Contractor shall deliver to Owner a written list of the names of all persons and entities intended to be employed by Contractor as Subcontractors to work on Improvements. 15 S:\projects\611\12\05\3.0 Construction\3.1 Contracts and Specifications\3.1.1 Contracts\Paving Contract\Contract Book\Liberty Trails Phase 5 Paving_Contract Book - To Be Signed By Contractor.doc 12.2 Should Owner have any objections to the employment of any person or entity named on the list of Subcontractors delivered to Owner pursuant to the foregoing paragraph, Owner shall serve written notice of such objection on Contractor within five (5) business days after the delivery of such list and Contractor shall substitute another person or entity acceptable to Owner in place of the person or entity to whom such objection was made. 12.3 Contractor shall not employ any person or entity as a Subcontractor on the Improvements that has been objected to by Owner. Failure of Owner to serve written notice on Contractor pursuant to Paragraph 12.2 of any objections it may have to any person or entity named on the list of Subcontractors within five (5) business days after the delivery of such list to Owner shall constitute approval by Owner of the employment of such person or entity as a Subcontractor on the Improvements. 12.4 Contractor shall be as fully responsible to Owner for the acts and omissions of its Subcontractors and of persons either directly or indirectly employed by such Subcontractors as Contractor is for the acts and omissions of persons directly employed by Contractor. 12.5 Nothing contained in this Article or in any of the Contract Documents shall create a contractual relationship of any kind between any Subcontractor and Owner. ARTICLE 13 – PROTECTION AND CHARACTER OF WORKMEN 13.1 Contractor shall take all necessary precautions for the safety of persons employed to work on the Improvements and shall without limiting the generality of the foregoing (i) comply with all applicable provisions of any federal, state, county, or municipal safety laws, ordinances, regulations, or building codes, to prevent injury to such persons while on, about, or adjacent to the Premises, (ii) properly erect and maintain at all times such safeguards for the protection of persons employed to work on the Improvements as the conditions and progress of the Work may require and (iii) conspicuously post such signs as may be necessary to warn persons employed to work on the Improvements of all latent hazards known to and created by Contractor existing on the Premises. 13.2 Contractor shall at all times be responsible for the conduct and discipline of Contractor’s employees and/or any Subcontractor or persons employed by Subcontractors. All workmen must have sufficient knowledge, skill, and experience to perform properly the work assigned to them. Any supervisor, foreman, or workmen employed by Contractor or any Subcontractor who does not perform his work in a skillful manner or appears to be incompetent or to act in a disorderly or intemperate manner shall, at the written request of Owner, be discharged immediately and shall not be employed again in any portion of the Work without the approval of Owner. 16 S:\projects\611\12\05\3.0 Construction\3.1 Contracts and Specifications\3.1.1 Contracts\Paving Contract\Contract Book\Liberty Trails Phase 5 Paving_Contract Book - To Be Signed By Contractor.doc ARTICLE 14 – PROTECTION OF PROJECT 14.1 Contractor shall furnish and install at its own cost and expense such material and devices as are customarily furnished by similar contractors in the industry to protect the Improvements or any part thereof from damage or destruction by rain, wind, or the elements prior to full and final completion of the Improvements. Contractor shall be responsible for such protection of the Improvements until acceptance by Owner. 14.2 In the event of an emergency endangering life or property, Contractor shall perform any work and shall furnish and install any materials and equipment necessary or prudent during the emergency.

C.1 �cai�� ,�.,, .,�,,,.,,: GEOTECHNICAL ENGINEERING REPORT 1 INTRODUCTION The proposed project is located north of the intersection of John Day Road and State Highway 114 (SH 114) in Fort Worth, Texas. The Liberty Trails Phase 5 will consist of developing 144 single-family residential lots, with associated utilities and paved streets. Based on topographic information provided by the client, the site generally slopes downward from the northwest to the southeast, with elevations ranging from approximately 775 feet to 754 feet. Based on proposed grading plans, we understand that up to approximately 3 feet of cut and 7 feet of fill will be required to achieve final grades within the proposed building pads. At the time of our field exploration, the site generally consisted of an open grass-covered field. Based on grading plans provided to us, several retaining walls are planned at the site. Global stability analysis of these retaining walls is outside the scope of this report; however, Rone would be pleased to provide a proposal for these services upon request. A site vicinity map and geology map are attached as Plates A. � and A.2, respectively. The general location and orientation of the site are shown on the Boring Location Diagram, Plate A.3, in Appendix A of this report. 2 PURPOSES AND SCOPE OF STUDY The principal purposes of this study are to review available information on the general subsurface conditions at the site and to develop geotechnical recommendations for the design and construction of foundations and pavements for Phase 5 of the Liberty Trails community. To accomplish its intended purposes, the study was conducted in the following phases: • Sample borings were drilled to evaluate the subsurface conditions at the boring locations, and to obtain soil and rock samples; • Laboratory tests were conducted on selected samples recovered from the borings to estimate the pertinent engineering characteristics of the foundation materials; and • Engineering analyses were performed using field and laboratory data to develop foundation and pavement design recommendations. l �' -- - _ -- - - --- - -- IIIIha:1�, �� Il��.iik f lo� r i a'�; _ R�hl�,,.,; ��, 3 FIELD OPERATIONS AND LABORATORY TESTING Subsurface conditions for Phase 5 of the proposed development were determined with a total of 33 borings performed to the depths of approximately 20 feet below the existing ground surface. The borings were located in the field by Rone personnel using an aerial photograph of the site and measuring from available site features. The latitude and longitude of the boring locations were measured using a hand-held GPS unit. Ground surFace elevations at the boring locations were interpolated from topographic information provided by the client. The provided locations and elevations are accurate only to the extent implied by the technique used in their determination. The approximate boring locations are shown on Plate A.3, Boring Location Diagram. Sample depth, description of soils, and classification (based on the Unified Soil Classification System) are presented on the Logs of Boring. Keys to terms and symbols used on the logs are also included. Laboratory soil tests were performed on selected samples recovered from the borings to confirm visual classification and determine the pertinent engineering properties of the soils encountered. Classification test results are presented on the Logs of Boring. 4 GENERAL SITE CONDITIONS 4.1 Site Geology Based on the subsurface conditions encountered in the borings and the Geologic Atlas of Texas, Dallas Sheet, the site appears to be located within the undivided Fort Worth Limestone and Duck Creek Formation (mapped as Kfd). The USGS Mineral Resources On-Line Spatial Data reference contains the following description of this formation: The Fort Worth Limestone is generally light to medium gray, and weathers to a yellow brown. It often contains marine fossils and is generally overlain by medium gray to yellow-brown calcareous clay. The Duck Creek formation generally consists of highly active residual clay underlain by medium gray to yellow-gray limestone. Please note that the geologic mapping was originally performed using aerial photography. Local variations and anomalies do occur. Libe PAGE �2 ��;,��.�.�, 4.2 SubsurFace Soil Conditions The various strata encountered in the borings and their approximate depths and thickness are shown on the Logs of Boring. The stratification boundaries shown on the Logs of Boring represent the approximate locations of changes in types of soil and rock; in-situ, the transition between material types may be gradual and indistinct. A brief summary of the stratigraphy indicated by the borings is given below. Based on the soil boring and laboratory data, the soils at this site generally consist of native lean clay (CL), fat clay (CH), sandy lean clay (CL), sandy fat clay (CH), and clayey sand (SC) containing various amounts of sand, gravel, calcareous nodules, and ferrous nodules extending to depths in the borings of approximately 5 to 12 feet below the existing ground surface. Underlying the clays, the borings generally encountered tan weathered limestone and/or gray limestone to the boring termination depth of approximately 20 feet. The plasticity index (PI) of the cohesive samples tested varied from 10 to 63, indicating low to high soil plasticity. A high plasticity index is generally associated with an increased potential for the active clayey soils to shrink and swell with changes in moisture content. In situ moisture levels ranged from approximately 10 percent below to 11 percent above their measured plastic limits, indicating a wide range of existing subgrade moisture conditions. 4.3 Groundwater Free water was not encountered in borings during drilling or at drilling completion. The scope of work did not include long-term observations of ground water or perched water conditions. In addition, it is difficult to accurately predict the magnitude of subsurface water fluctuations that might occur following periods of drought or rainfall. Groundwater can be encountered above any of the less permeable soil or rock at this site, creating a temporary perched water condition, particularly during wet periods of the year. Groundwater levels should be expected to fluctuate throughout the year with variations in precipitation, runoff, the water levels in nearby surface water features, and other factors not evident at the time of the field services. These observations have been made during the course of the field exploration, as indicated on the Logs of Boring. A groundwater study has not been performed. Long-term observations would Liberty Trails Phase 5 F��JN� 1:.1�'�N11 be necessary to more accurately evaluate the groundwater levels and fluctuations. Rone would be pleased to provide groundwater level monitoring as an additional scope of services, if desired. 5 ANALYSIS AND RECOMMENDATIONS 5.1 Seismic Site Class The site class for seismic design is based on several factors that include soil profile (soil or rock), shear wave velocity, density, relative hardness, and strength, averaged over a depth of 100 feet. The borings for this project did not extend to a depth of 100 feet; we have assumed the soil and rock conditions below the termination depth of the borings to be similar to those encountered at the termination depth of the borings. Based on Section 1613.3.2 of the 2018 International Building Code and Table 20.3-1 of ASCE 7-10, we recommend using Site Class C(Stiff Soil/Soft Rock) for seismic design. 5.2 Potential Vertical Rise The estimated Potential Vertical Rise (PVR) using the TxDOT method, based on a 12-foot deep active zone and the depth to weathered limestone, is estimated to range from less than 1 inch to approximately 4 inches for subgrade soils in a dry moisture condition. Soil moisture levels do not remain constant over time. If the soils in these areas are allowed to dry appreciably, prior to and/or during construction, ground movements could exceed the estimated values when the soils are subsequently given free access to water. For this project, we recommend that foundations be designed based on a PVR of approximately 1 to 4 inches. Details regarding subgrade treatment are presented in Section 5.4 Foundation Recommendations and Section 5.5 Subgrade Preparation. 5.3 Excavation Safety Considerations Please note that in accordance with Texas State Law, the design and maintenance of excavation safety systems is the sole responsibility of the contractor. Please reference Occupational Safety and Health Administration (OSHA) Standards 29 CFR —1926 Subpart P for guidance in the design of such systems. All excavations should be sloped, shored, or shielded in accordance with OSHA requirements. Project No. 21-24902 Liberty Trails Phase 5 J RtJN�,�.,. �,,,,.,., 5.4 Foundation Recommendations Based on the conditions encountered in the borings, the proposed site grading, and the anticipated loading conditions, the proposed residences may be supported on slab foundations bearing on tested and approved native soils, moisture conditioned fill, select fill, or weathered limestone. Foundation design recommendations are provided below. The proposed residences may be supported on ground-supported foundations consisting of a conventionally reinforced beam and slab system or a post-tensioned slab foundation system, provided the estimated floor movements can be tolerated. Foundations should be designed with exterior and interior grade beams adequate to provide sufficient rigidity to the foundation system to tolerate the vertical soil movements expected at this site. A net allowable soil bearing pressure of 2,000 pounds per square foot (psf) may be used for design of all grade beams bearing in native soils or select fill. A net allowable soil bearing pressure of 1,500 pounds per square foot (psf) may be used for design of all grade beams bearing in moisture conditioned fill. The allowable bearing pressure may be increased to 5,000 psf in weathered limestone. Grade beams should bear at least 18 inches below final grade. Relatively shallow weathered limestone was encountered in some of the borings at this site. If weathered limestone is encountered in only a portion of the foundation excavation at the planned bearing elevation, the excavation should be extended such that the entire foundations is bearing on weathered limestone at the lower elevation. As an alternative, excavations can be extended at least 6 inches into the weathered limestone, and the excavated limestone can be compacted back into the excavation up to the bearing elevation to help reduce the "hinge" condition associated with the transition from soil to rock. The bottom of the beam trenches should be free of any loose or soft material prior to the placement of the concrete. All grade beams and floor slabs should be adequately reinforced to minimize cracking as normal movements occur in the foundation soils. Moist soil conditions should be maintained beneath and at least 5 feet beyond slab foundations during their service life. The Post-Tensioning Institute (PTI) parameters are calculated based on the method described in the most recent edition of the PTI manual for designing slab-on-grade foundation systems. -� _:_ �,:�r�� ;��.��_'-�.' k� Liberty Trails Phase 5 , L�� I --�'�;':Y, R(�N� % I�. l�� ti f 1� 1.� �� Recommended PTI foundation design parameters for a PVR value of 1 and 4 inches and a Thornthwaite Moisture Index (TMI) of minus five (-5) are as follows: Table 1: PTI Criteria Parameter Edge Moisture Variation Distance, e,,, (feet) Differential Soil Movement, ym (inches) Condition Center Lift Edge Lift Center Lift Edge Lift 1 inch 7.5 3.4 0.8 1.2 1.5 4 inches 7.5 3.4 1.7 � A moisture barrier should be used beneath slab foundations. The combination of wet conditions and growth of mold and mildew can create a persistent slip hazard. The PTI method incorporates numerous design assumptions associated with the derivation of variables needed to estimate the soil design criteria. The PTI method of predicting differential soil movement is applicable when soil moisture conditions are controlled solely by the climate on well- graded building pads (i.e. proper drainage, no percolation of water in unlined landscaped areas, no utility water leaks, or other free water sources). Soil moisture typically increases within the subgrade beneath concrete slabs, particularly when the space above the floor slab is enclosed and air-conditioned. As soil moisture increases, the soils may swell. The PTI design method is intended to provide stiffened foundation systems that can perform well under typical natural changes in soil moisture. The differential foundation movements resulting from seasonal soil moisture content changes are typically much lower than movements that can occur due to free water sources near or beneath the structure, which are not directly addressed by the PTI design method. 5.5 Subgrade Preparation When considering the various subgrade preparation options, it is important to keep in mind that the subsurface conditions which resulted in the estimated PVR values may not be uniformly present beneath each structure. Some allowance for variable support should be incorporated into the foundation designs for structures at this site. The preparation of a uniform pad beneath each structure is a crucial aspect of site development. To help provide a uniform pad, the depth of fill . - . � • � � - ------- -� Design PVR Value 3 inches 7.5 3.4 1.3 R�NE � I.I��ryll_�I�'ii beneath an individual structure should be uniform within the building footprint, to the extent possible. 5.6 Subgrade Fill Over-excavation is not required to perform moisture conditioning; however, all fill placed within the proposed building pads should be placed following the soil preparation and placement procedures and requirements presented in this report. The controlled fill should extend at least 5 feet outside the perimeter of the proposed structures or other perimeter features sensitive to differential movement. Any deleterious materials or rock fragments greater than approximately 4 inches in diameter encountered within the soils should be removed. The subgrade that will receive fill should be scarified to a depth of 6 inches and compacted to 95 to 100 percent of the material's standard Proctor dry density (ASTM D698) at a moisture content above optimum. In order to achieve a more uniform soil moisture profile, fill should be placed in maximum 10-inch loose lifts and compacted to a similar density and moisture content. Fill placement in the building pad and pavement subgrades should be monitored and tested on a full-time basis by Rone Engineering to confirm conditions are as anticipated and to confirm the fill is suitable and placed with the proper moisture content and degree of compaction. Density tests should be performed on each lift of reworked clay. 5.7 Pavement Design Recommendations This report includes recommendations for rigid pavements. Maintenance requirements over the life of rigid pavements are typically much lower than flexible pavements, and many consider the long-term appearance of rigid pavements an advantage. Rigid pavements tend to be more durable and require less maintenance after construction, and rehabilitation/reconstruction of the pavement section is not typically considered a part of the pavement life cycle. 5.7.1 General Discussion Based on the subsurFace conditions encountered in our borings, the anticipated traffic loading conditions, and our local experience, we recommend the proposed pavement consist of jointed Liberty Trails Phase 5 �� , ��„�:,,; reinforced concrete pavement (JRCP) supported by lime-treated subgrade. Recommendations for pavements and subgrade treatment are described in the following sections. 5.7.2 Subgrade Support Laboratory test results published correlations with index soil properties, and experience with similar materials were used to estimate a design California Bearing Ratio (CBR) value approximately 3, which was correlated to a resilient modulus, MR, of approximately 4,100 psi. This value correlates with, yet is slightly lower than, numerous resilient modulus values measured in TxDOT projects performed in similar soil types in the Dallas/Fort Worth area. 5.7.3 Pavement Thickness During pavement design, subgrade conditions must be considered along with expected traffic use/frequency, pavement type, and design life. Based on laboratory test results and local design experience, the information in the following table was used in our analysis. If actual traffic counts are available, we can recalculate the design sections based on actual traffic values.

Based on the analyses, we recommend the following pavement sections: Table 3: Recommended Pavement Sections Thickness (inches) Material Collector Streets Residential Streets Jointed Reinforced Concrete � 8 Lime-Treated Subgrade � 6 : . � The concrete pavement should have between 4 and 6 percent entrained air. We recommend 3,600 psi compressive strength concrete be used to provide a 530-psi modulus of rupture. Hand- placed concrete should have a maximum slump of 6 inches. A sand leveling course should not be permitted beneath pavements. All steel reinforcement, dowel spacing/diameter, and pavement joints should conform to local municipal standards. 5.7.4 Pavement Subgrade Preparation All topsoil, vegetation, and any unsuitable materials should be removed. The pavement subgrade should be proofrolled with a fully loaded (40,000 Ibs.), tandem-axle dump truck or similar pneumatic-tire equipment to locate areas of unsuitable subgrade. In areas to be cut, the proofroll should be performed after the final grade is established. In areas to be filled, the proofroll should be performed prior to placement of engineered fill and after subgrade construction is complete. Areas of loose or soft subgrade encountered in the proofroll should be removed and replaced with engineered fill, or moisture conditioned (dried or wetted, as needed) and compacted in place. The existing soils are plastic and can undergo volume change when subjected to moisture variations. If moisture levels in the upper soils decrease, they may shrink and cracks may develop. If the moisture levels of these materials increase, they could swell and lose strength. Shrinkage, swelling, or strength loss could be detrimental to the proper function of the pavement. Lime treatment of clay subgrade is recommended for all concrete pavements to provide more uniform subgrade support and improve these soil's strength characteristics. Project No. 21-24902 Liberty Trails Phase 5 � F�� N� � r. �� ti f 1_� �. Lime treatment should be perFormed in accordance with Item 260, current Standard Specifications for Construction of Highways, Streets, and Bridges, Texas Department of Transportation (TxDOT). We recommend that the actual percentage of lime required be confirmed by collecting soil sample(s) once pavement subgrade elevation is attained. A lime series should be perFormed on the samples collected and the results should be used to determine the actual percentage of lime required. Lime treating the upper 6 inches of the subgrade soils will not significantly reduce the normal shrinking and swelling of the subgrade that occurs with seasonal moisture variation. Some vertical movements of the pavements should be expected. Grading and compaction of pavement subgrade should follow the recommendations in Section 6 Site Preparation and Fill Placement below. The final grades should facilitate proper drainage to reduce access of surface water to the subgrade materials. Water can be introduced beneath the pavement through granular materials used for aggregate bases and utility line embedment, and can cause differential movement in the pavement. Aggregate base or a granular leveling course should not be used beneath pavements. To reduce the risk of moisture access and possible swelling, consideration could be given to substituting clay plugs for granular embedment material around all utilities at the edges of the pavement. 6 SITE PREPARATION AND FILL PLACEMENT The following recommendations for site preparation and fill placement may contain elements that do not appear to apply to the presently known conditions at the project site. These items have been included based on our experience that unforeseen obstacles can be encountered, and progress can be delayed while written guidance is prepared. While we cannot cover every possible circumstance, we have attempted to address the most frequently occurring issues in this report section. 6.1 General All grade-supported slabs should be designed to accommodate anticipated potential movements as presented in the "Potential Vertical Rise" section of this report. Liberty Trails Phase 5 P A G E � 10 �_ RONE / rnc�n�r�i��,/ � Every attempt should be made to limit the extreme wetting or drying of the subsurFace soils because swelling and shrinkage of these soils will result. Standard construction practices of providing good surFace water drainage should be used. All grading should provide positive drainage away from the paving and should prevent water from collecting near the edge of pavements and structures. Also, ditches or swales should be provided to carry the run-off water both during and after construction. Lawn areas should be watered moderately, without allowing the clay soils to become too dry or too wet. Roof runoff should be collected by gutters and downspouts, and should discharge away from the building or into storm drains. Backfill for utility lines or along the perimeter beams should consist of site-excavated soil. If the backfili is too dense or too dry, it will swell, and a mound will form along the trench line. If the backfill is too loose or too wet, it will settle, and a depression will form along the trench line. Backfill shouid be compacted as recommended in the "Site Preparation and Fill Placement" section of this report. If granular material is used for embedment in utility trenches, we recommend placing a clay plug as a replacement for the granular embedment at the location where the city line is located, at the location where the utility enters the structure, and at other connections. The intent is to prevent free moisture from passing through the granular embedment and entering the soil beneath the structure. Root systems from trees and shrubs can draw a substantial amount of water from the clay soils at this site, causing the clays to dry and shrink. This could cause settlement beneath grade- supported slabs such as floors, walks, and paving. Trees and large bushes should be located a distance equal to at least their anticipated mature height away from grade slabs. 6.2 Site Preparation Preparation of the site for any future construction should include the removal and proper disposal of any obstructions that would hinder construction. These obstructions include all abandoned structures, foundations, debris, water wells, septic tanks, and loose material. It is the intent of these recommendations to provide for the removal and disposal of all obstructions not specifically provided for elsewhere by the plans and specifications. Liberty Trails Phase S _ P A G E � 11 `___ �1 ��,�, .,��.�. In general, we recommend that all active utilities that would extend beneath the buildings, and are not intended to provide service to the structure, be rerouted around the building footprint. Any abandoned lines should be removed and disposed of properly. All abandoned utilities within the buildings that are not removed represent a risk to future building perFormance; if the lines are abandoned in place, they must be fully grouted and capped so that the pipes do not provide a ready conduit for water. Utility excavation and/or subgrade treatment may encounter shallow weathered limestone which can be difficult to excavate. The selected contractor should have experience in construction and excavation within this material. It should be noted that this study did not include evaluating the ease or difficulty of excavation of the subsurFace materials at this site. The contractor should use his own experience in the area when forming conclusions regarding appropriate means and methods to accomplish the planned construction. All concrete, trees, stumps, brush, abandoned structures, roots, vegetation, rubbish and any other undesirable matter should be removed and disposed of properly. It is the intent of these recommendations to provide a loose surface with no features that would tend to prevent uniform compaction by the equipment to be used. All areas to be filled should be disced or bladed until uniform and free from large clods. Soils should be brought to the proper moisture content and compacted as indicated in the Fill Placement Criteria table below. Fill that will be 10 feet or deeper below final grades should be compacted to 97 to 100 percent of its maximum dry density at a moisture content within the range of 0 to 3 percent above optimum (ASTM D698).

If select fill is used, it should consist of a clean, natural soil meeting the criteria recommended above. The fill should have a moisture content within the specified range, be placed in loose lifts less than 9 inches thick, and compacted as indicated. Lime-treated, on-site soils may also be used as select fill, provided the PI of the treated material meets the specifications for select fill. The quantity of lime needed to achieve the PI requirement for select fill is not known. The actual percentage of lime should be determined once soils have been stockpiled and sampled. Crushed limestone or recycled concrete can also be used as select fill. The crushed limestone or recycled concrete should meet the criteria listed in the Fill Placement Criteria table. The material should have a moisture content within the specified range, be placed in loose lifts less than 9 inches thick, and compacted as indicated in the table. 6.4 Moisture and Density Testing Field moisture and density tests should be made by the geotechnical engineer or his representative. Tests should be taken in each layer of the compacted material below the disturbed surface. If the materials fail to meet the specified moisture and/or density, the course should be reworked as necessary to obtain the specified criteria. Liberty Trails Phase 5 '� P A G E � 13 ��.,; ��„�.U�, Proper moisture content and compaction must be maintained until placement of the overlying lift, or construction of overlying flatwork. Failure to maintain the moisture content and compaction could result in excessive soil movement that can have a detrimental effect on structures supported on or above the fill. The contractor should provide some means to control the moisture content and compaction (such as water hoses, water trucks, etc.). Maintaining subgrade moisture and compaction is always critical, but will require extra effort during warm, windy, and/or sunny conditions. Density and moisture testing is recommended to provide some indication that adequate earthwork is being performed; however, the quality of the fill is the sole responsibility of the contractor. Satisfactory testing is not a guarantee of the quality of the contractor's earthwork operations. 6.5 Site Grading Site grading operations should be performed in accordance with the recommendations provided in this report. Grading plans and construction operations should strive to achieve positive drainage around all sides of the proposed structures. Inadequate drainage around structures supported on-grade will likely cause excessive vertical movement to occur. 6.6 Utility Backfill If granular material is used for embedment in utility trenches, we recommend placing a clay plug, as a replacement for the granular embedment, at the location where the city line is located, at the location where the utility enters or passes beneath the pavement, and at other connections. The intent is to prevent free moisture from passing through the granular embedment and entering the soil beneath the pavement. On-site clayey soils should be used as backfill. These materials should be placed in maximum 6-inch lifts and properly compacted to between 95 and 100 percent of the maximum dry density, as determined by Standard Moisture Density Relation test (ASTM D698), and at a moisture content of at least two percent (min +2°/o) above the soil's optimum moisture content. In instances where utility lines are more than 10 feet deep, the backfill below 10 feet should be compacted to 100 percent of the maximum dry density, as determined by Standard Moisture Density Relation test (ASTM D698), and at a moisture content of within two percent (-2 to +2%) of the soil's optimum moisture content. i�"'� PAGE �14 Liberty Trails Phase 5 - ��M��,,�: ��., Compacted clay fill will typically experience settlement on the order of 1 to 2 percent of the fill thickness. This should be considered when designing utility lines beneath pavements, flatwork or any structure. 6.7 Construction Observations In any geotechnical study, the design recommendations are based on a limited amount of information about the subsurface conditions. In the analysis, the geotechnical engineer must assume the subsurface conditions at the site are similar to the conditions encountered in the borings; however, during construction, anomalies in the subsurface conditions are often revealed. The potential for the presence of varied geologic formations and significantly different support conditions at this site, which could result in changes in our design recommendations, increases the risk of damaging soil movements at this site. Therefore, it is recommended that Rone Engineering Services, Ltd. be retained to observe earthwork and foundation construction, and perform materials evaluation and testing 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 conditions. 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, final depth of undercut of expansive soils for non-expansive earth fill pads, and other such subsurface-related recommendations should be considered preliminary. We recommend 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 to contract directly with the project geotechnical engineer. This results in clear, direct lines of communication among the owner, the owner's design engineers, and the geotechnical engineer. 7 STUDY CLOSURE The analyses, conclusions, and recommendations contained in this report are based on site conditions as they existed at the time of the field exploration and further on the assumption that the exploratory borings are representative of the subsurface conditions throughout the site; that . t �'9� e _• � `-�i`�`'�� K�—f y:i- :4i�i`3e-7,'��y:_,�',�j'��` -CibertyTrails Phase 5 ' - - R(JN � % , �. ,, � , �_� is, the subsurFace conditions everywhere are not significantly different from those disclosed by the borings at the time they were completed. 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 we can review these changed conditions and reconsider our recommendations where necessary. If there is a substantial lapse of time between submission of this report and the start of the work at the site, if conditions have changed due either to natural causes or to construction operations at or adjacent to the site, or if structure locations, structural loads, or finished grades are changed, we urge that we be promptly informed and retained to review our study to determine the applicability of the conclusions and recommendations, considering the changed conditions and/or time lapse. We recommend that Rone Engineering Services, Ltd. be retained to review those portions of the plans and specifications for this particular project that pertain to earthwork and foundations as a means to determine whether the plans and specifications are consistent with the recommendations contained in this report. In addition, we are available to observe construction, particularly the compaction of structural fill, backfill, and/or the construction of foundations as recommended in the report, and such other field observations as might be necessary. This study has been completed for the exclusive use of the client and their designated agents for specific application to design of this project. We have used that degree of care and skill ordinarily exercised under similar conditions by reputable members of our profession practicing in the same or similar locality. No warranty, expressed or implied, is made or intended. 8 COPYRIGHT 2021 RONE ENGINEERING SERVICES, LTD.

The borings were completed at locations staked in the field by Rone personnel. The borings were advanced between sample intervals using continuous flight auger drilling procedures. The results of each boring, including sample depth, description, and soil classification based on the Unified Soil Classification System (USCS), are shown on the Logs of Boring. Keys to the symbols and terms used on the Logs of Boring are presented in Appendix A. Relatively undisturbed samples of cohesive soils were obtained using a tube sampler at the depths indicated on the Logs of Boring. The tube sampler consists of a nominal 3-inch diameter steel tube with a sharp cutting edge connected to a head equipped with a ball valve threaded for rod connection. The tube is hydraulically pushed into the soil. The soil specimens were extruded from the tube in the field, described, tested for consistency with a hand penetrometer, and packaged to reduce moisture loss. The consistency of cohesive soil samples was evaluated in the field using a calibrated hand penetrometer. In this test, a'/4-inch diameter piston is pushed into a relatively undisturbed sample at a constant rate to a depth of approximately'/4 inch, and the piston penetration resistance is recorded in tons per square foot (tsf) at the appropriate depth on the Logs of Boring. When the capacity of the penetrometer is exceeded, the value is tabulated as 4.5+. Samples of stiff and/or granular materials were obtained using split-barrel sampling procedures in general accordance with ASTM D1586. In the split-barrel procedure, a disturbed sample is obtained in a standard 2-inch OD split-barrel sampler driven 18 inches into the ground using a 140-pound hammer falling freely 30 inches. The number of blows for the last 12 inches of the 18- inch penetration is recorded as the Standard Penetration Test resistance (N-value). The N-values are recorded on the Logs of Boring at the depth of sampling. The samples were packaged and returned to our laboratory for further examination and testing. fe�il RC�IV� ��,; �,,,��; Rock and rock-like materials encountered in the borings were evaluated with a modified version of the Texas Cone Penetration (TCP) test. 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 hammer blow. This method was modified by using a 140-pound hammerfalling 30 inches, resulting in 350 foot-pounds of per blow. In relatively soft materials, the penetrometer cone is driven 1 foot and the number of blows required for each 6- inch increment is recorded at the respective test depth on the log of boring. In hard materials (rock or rock-like), the penetrometer cone is driven 100 blows, and the resulting penetration distances are recorded in inches for the first and second sets of 50 blows. The penetration for the total 100 blows is recorded at the respective testing depths on the Logs of Boring. Groundwater observations during and at completion of drilling are shown on the Logs of Boring. Upon completion of the borings, the boreholes were backfilled with auger cuttings to ground level. � R�N� 1 M1 I�� h I 1 I I.Y li LABORATORY TESTING Laboratory tests were performed on selected samples recovered from the borings to evaluate the engineering characteristics of the subsurFace materials encountered and to provide data for developing engineering design parameters. The subsurface materials recovered during the field exploration were described by an engineering geologist or senior staff inember in the field and/or the laboratory and were later refined based on results of the laboratory tests. The samples were visually classified and described, in part, using the Unified Soil Classification System (USCS). Visual classification of soils was confirmed for selected samples using index property testing including natural moisture content, Atterberg limits, and gradation tests (percent passing the No. 200 U.S. Standard Sieve). All testing was perFormed in general accordance with applicable American Society for Testing and Materials (ASTM) procedures as follows: Test ASTM Standard Number Atterberg Limits D4318 Percentage of Particles Passing the No. 200 Sieve D1140 Moisture Content D2216 Dry Unit Weight D2167 Unconfined Compressive Strength D2166 Swell Test D4546, Method B Swell Test In the swell test, a sample is placed in a consolidometer and subjected to the estimated overburden pressure. The sample is then inundated with water and allowed to swell. Moisture contents are determined both before and after completion of the test. Test results are recorded as the percent swell, with initial and final moisture content. Detailed swell test results are tabulated in Appendix A. Unconfined Compression Strength Test In the unconfined compression test, a cylindrical specimen is subjected to axial load at a constant rate of strain until failure occurs. Strengths determined by this test are tabulated at their respective sample depths on the Logs of Boring. Results of natural moisture content and dry unit weight determinations are also tabulated at the respective sample depths on the logs. � APPENDIX C The Geoprofessional Business Association (GBA) has prepared this advisory to help you — assumedly a client representative — interpret and apply this geotechnical-engineering report as effectively as possible. In that way, you can benefit from a lowered exposure to problems associated with subsurface conditions at project sites and development of them that, for decades, have been a principal cause of construction delays, cost overruns, claims, and disputes. If you have questions or want more information about any of the issues discussed herein, contact your GBA-member geotechnical engineer. Active engagement in GBA exposes geotechnical engineers to a wide array of risk-confrontation techniques that can be of genuine benefit for everyone involved with a construction project. Understand the Geotechnical-Engineering Services Provided for this Report Geotechnical-engineering services typically include the planning, collection> interpretation, and analysis of exploratory data from widely spaced borings and/or test pits. Field data are coinbined with results from laboratory tests of soil and rock samples obtained from field exploration (if applicable), observations made during site reconnaissance, and liistorical information to form one or more models of the expected subsurface conditions beneath the site. Local geology and alterations of the site surface and subsurface by previous and proposed construction are also important considerations. Geotechnical engineers apply their engineering training, experience, and judgment to adapt the requirements of the prospective project to the subsurface model(s). Estimates are made of the subsurface conditions that will likely be exposed during construction as well as die expected performance of foundations and other structures being planned and/or affected by construction activities. The culminaUon of these geotechnical-engineering services is typically a geotechnical-engineering report providing the data obtained, a discussio❑ of the subsurface model(s), the engineering and geologic engineering assessments and analyses made, and the recommendations developed to satisfy the given requirements of the project. These reports may be tided investigations, explorations, studies, assessments, or evaluations. Regardless of the tide used, the geotechnical-engineering report is an engineering interpretation of tlie subsurface conditions within the context of the project and does not represent a close examination, systematic inquiry, or d�orough u�vestigation of all site and subsurface conditions. Geotechnical-Engineering Services are Performed for Specific Purposes, Persons, and Projects, and At Specific Times Geotechnical engineers structure their services to meet die specific needs, goals, and risk management preferences of their clients. A geotechnical-engineering study conducted for a given civil engineer will not likely meet the needs of a civil-works constructor or even a different civil engineer. Because each geotechnical-engineering study is unique, each geotechnical-engineering report is unique, prepared solely for the client. Likewise, geotechnical-engineering services are performed for a specific project and purpose. For example, it is unlikely that a geotechnical- engineering study for a refrigerated warehouse will be the same as one prepared for a parking garage; and a few borings drilled during a preliminary study to evaluate site feasibility will not be adequate to develop geotechnical design recommendations for the project. Do not rely on this report if your geotechnical engineer prepared it: . for a different client; • for a difEerent project or purpose; . for a different site (that may or may not include all or a portion of the original site); or . before important events occurred at tl�e site or adjacent to it; e.g., man-made events like construction or environmental remediation, or natural events like floods> droughts, earthquakes, or groundwater fluctuations. Note, too, the reliability of a geotechnical-engineering report can be aftected by the passage of time, because of factors like changed subsurface conditions; new or modified codes, standards, or regulations; or new techniques or tools. If yoti nre the lenst bit i�ncertnin about the continued reliability of this report, contact your geotechnical engineer before applying die recommendations in it. A minor amount of additional testing or analysis after the passage of time — if any is required at all — could prevent major problems. Read this Report in Full Cosdy proUlems have occurred because those relying on a geotechnical- engineering report did not read the report in its entirety. Do not rely on an executive summary. Do not read selecdve elements only. ReAd and refer to the report in full. You Need to Inform Your Geotechnical Engineer About Change Your geoteclmical engineer considered unique, project-specific factors when developing the scope of study behind this report and developing the confirmation-dependent recommendations the report conveys. Typical changes that could erode the reliability of this report indude those that affect: . the site's size or shaye; . the elevation, configuration, location, orientation, function or weight of the proposed structure and the desired performance criteria; . the comyosition of the design team; or . project ownership. As a general rule, nhvnys inform your geotechnical engineer of project or site changes — even minor ones — and request an assessment of their impact. 71te geotechnicnl engi�ieer tivlio prepnred tltis report ca��not nccept ■ ■ ■ �I I � �•esponsibility or liability for problems that nrise 1�ecause the geotechnicnl engineer was not infonnerl nbout developments the engineer othertivise would have considered. Most of the "Findings" Related in This Report Are Professional Opinions Before construction Uegins, geotechnical engineers explore a site's subsurface using various sampling and testing procedures. Geotechnicnl engi�ieers can observe actunl su�surjnce coriditions anly nt Niose spe��c locations lvhere s�rripli�ig nrid te�ti�tg is perfor�ried. The data derived from that sampling and testing were reviewed by your geotechnical engineer, who dien applied professional judgement to form opinions about subsurface conditions throughout the site. Actual sitewide-subsurface conditions inay differ - inaybe significantly - from tliose indicated in this report. Confront that risk Uy retaining your geotechnical engineer to serve on the design teatn through project completion to obtain infonned guidance quicldy, whenever needed. This Report's Recommendations Are Confirmation-Dependent The recommendatIons included in diis report - including any options or alternatives - are confirmation-dependent. In other words, they are not final, because the geotechnical engineer who developed them relied heavily on judgemeut and opiiuon to do so. Your geotechnical engu�eer can finalize the recommendations only after observing actual subsurface conditions exposed duiing construction. If through observation your geotechnical enguieer confinns that the conditions assumed to exist actually do exist, the recommendations can be relied upon, assuming no other changes have occurred. Thegeotecl�nica! e»gineer who prepnred this report cannot assw��e responsibility or liability for confirmatio�i-dependent recommendations if you fail to retnin that engineer to perforni cottstruction observation. This Report Could Be Misinterpreted Other design professionals' misinterpretation of geotechnical- eugineering reports has resulted in costly problems. Confront that risk by having your geotechnical engineer serve as a continuing member of the design team, to: • confer with other design-team meinbers; . help develop specifications; . revietv pertinent elements of other design professionals' plans and specifications; and be available whenever geotechnical-engineering guidance is needed. You should also confront the risk of constructors misinterpreting this report. Do so Uy retaining your geotechnical engineer to participate in prebid and preconstruction conferences and to perform construction- phase observations. Give Constructors a Complete Report and Guidance Some owners and design professionals mistakerily believe they can shift unanticipated-suUsurface-conditions IiaUility to constructors by li�niting the information they provide for bid preparation. To help prevent the costly, contentious problems this practice has caused, include the complete geotechnical-engineering report, along with any attachments or appendices, with your contract documents, but be certnrn to noie conspiaiously that you've iriclu��ed tite mnterin! for i�tfor�riation pt�rposes only. To avoid misunderstanding, you may also want to note that "informational purposes" means constructors have no right to rely on the inteipretations, opinions, conclusions, or recommendations iu the report. Be certain that constructors luiow they may learu about specific project requirements, including options selected from the report, only frotn the design drawings and specifications. Remind constructors that they may perform their own studies if they want to, and be sure to allow enougli tinie to permit them to do so. Only then might you be in a position to give constructors the information available to you, while requiring them to at least share some of the financial responsibilities stemming fc•om unanticipated conditions. Conducting prebid and preconstruction confe►•ences can also be valuable in tliis respect. Read Responsibility Provisions Closely Some client representatives, design professionals, and constructors do not realize that geotechnical engineering is far less exact than otlier engineering disciplines. This happens in part because soil and rock on project sites are typically heterogeneous and not manufactured inaterials with well-defined engineering properties like steel and concrete. That lack of understatiding has nurtured unrealistic expectations that have resulted in disappointments, delays, cost overruns, claims, and disputes. To confront that risk, geotechnical engineers commonly include explanatory provisions in their reports. Sometimes labeled "limitations;' many of these provisions indicate where geotechuical engineers' responsibilities begin and end, to help others recognize their o�m responsibilities and risks. Renrl the�eprovisiats closely. Aslc questions. Your geotechnical eugineer should respond fully and franl�ly. Geoenvironmental Concerns Are Not Covered The personnel, equipment, and tecluiiques used to perform an eiivironmental st�idy - e.g., a"phase-one" or "phase-two" environmental site assessment - differ significandy from those used to perform a geotechnical-engineering study. For that reason, a geotechnical-engineering report does not usually provide environmental findings, conclusions, or reconunendations; e.g., about the likelihood of encounteruig underground storage tanks or regulated contaminants. U�ianticipated subsurface e��vironmentnl problems hnve led to project failures. Ifyou have not obtained your otiv�i enviroumental information about the project site, ask your geotech�ucal consultant for a recommendation on how to find environmental risk-tnanagetnent guidance. Obtain Professional Assistance to Deal with Moisture Infiltration and Mold While your geotechnical engineer may have addressed groundwater, water infiltration, ar similar issues in this report, the e�igineer's services were not designed, conducted, or intended to prevent migration of moisture - including water vapor - from the soil through building slabs and walls and into the building interior, where it can cause mold growth and material-performance deficiencies. Accordingly, proper trnple»ientntiort of the geotechntcal engineer�'s reco»unendatio►is will riot of itself Le sufficient to pr•event moisture i►ifiltration.
