Information includes, but is not limited to, locations of irrigation systems, franchise utilities, and other underground utilities. All existing structures, improvements, and utilities shall be adequately protected, at the expense of the Contractor, from damage that might otherwise occur due to construction operations. Where construction comes in close proximity to existing structures or utilities, or if it becomes necessary to move services, poles, guy wires, pipe lines, or other obstructions, it shall be the Contractor's responsibility to notify and cooperate with the utility or structure owner. The utility lines and other existing structures shown on the plans are for information only and are not guaranteed by the City to be complete or accurate as to location 1-10 and/or depth. It shall be the Contractor's responsibility to verify locations and depths sufficiently in advance of construction such that necessary adjustments may be made to allow for the proper installation of proposed improvements as indicated in the plans. The Contractor shall be liable for damage to any utilities resulting from the construction of this project. 6.3 All work shall be completed in accordance with the recommendations of the geotechnical study performed by Alliance Geotechnical Group Testing dated October 12, 2022; Report No. DE22-089 included in Appendix A of this document. 6.4 Before submitting a Bid, each Bidder will, at Bidder's own expense, make or obtain any additional examinations, investigations, explorations, tests and studies and obtain any additional information and data which pertain to the physical conditions (surface, subsurface and underground facilities) at or contiguous to the site or otherwise which may affect cost, progress, performance or furnishing of the Work and which Bidder deems necessary to determine its Bid for performing and furnishing the Work in accordance with the time, price and other terms and conditions of the Contract Documents. 6.5 On request in advance, the Owner will provide each Bidder access to the site to conduct explorations and tests as each Bidder deems necessary for submission of a Bid.

No substitutions should be considered during the bidding process. 10. Subcontractors, Suppliers, and Others. 10.1 If the Owner requests the identity of any Subcontractors, Suppliers, or other persons or organizations to be submitted to the Owner in advance of the specified date prior to the Effective Date of the Agreement, the apparent Successful Bidder, and any other Bidder so requested, shall within seven (7) days after the request submit to the Owner a list of all such Subcontractors, Suppliers and other persons and organizations proposed for those portions of the Work for which such identification is requested. Such list shall be accompanied by an experience statement with pertinent information regarding similar projects and other evidence of qualification for each such Subcontractor, supplier, person or organization if requested by the Owner. If the Owner, after due investigation, has reasonable objection to any proposed Subcontractor, Supplier, other person or organization, Owner may, before the Notice of Award is given, request the apparent Successful Bidder to submit an acceptable substitute in which case the apparent Successful Bidder shall submit an acceptable substitute. Bidder's Bid price may be increased (or decreased) by the difference in cost occasioned by such substitution, and the Owner may consider such price adjustment in evaluating Bids and making the contract award. If the apparent Successful Bidder declines to make any such substitution, the Owner may award the contract to the next lowest Bidder that proposes to use acceptable Subcontractors, Suppliers, other persons and organizations. The declining to make requested substitutions will not constitute grounds for sacrificing the Bid security of any Bidder. 10.2 No Contractor shall be required to employ any Subcontractor, Supplier, other person or organization against whom Contractor has reasonable objection. 1-12 11. Bid Proposal. 11.1 Two (2) completed Bid Proposals must be submitted in a sealed envelope as described in Item 15 of these Instructions to Bidders.

A corporation Bidder must name the state in which the organization is chartered. Bids which are signed for a corporation shall have the correct corporate name thereof, its post office address, and the signature of the president or other authorized officer of the corporation, manually written below the corporate name in the following manner: "By (name) - (corporate title) ." If the bid is made by a firm or partnership, the name and post office address of the managing member of the firm or partnership shall be given or the bid may be signed by an attorney-in-fact.

If the bid is made by an individual, his post office address shall be given. Bids which are not signed by the individuals making them shall have attached thereto a power of attorney evidencing authority to sign the bid in the name of the person for whom it is signed. 12. Provision Concerning Escalator Clauses. Bids containing any condition which provides for changes in the stated bid prices due to increase or decrease in the costs of materials, labor, or other items required for this project, may be rejected and returned to the Bidder without being considered. 13. Estimates of Quantities. The quantities listed in the Bid Form will be considered as approximate and will be used for the comparison of bids, unless stated otherwise in the description of pay items.

Bids will be received by the Procurement Agent, and shall be submitted to the Procurement Office at the City of Coppell Town Center, 255 E. Parkway Boulevard, Coppell, Texas 75019 until 2:00 p.m. on Thursday, August 21, 2025, and then publicly opened and read aloud in-person and via a Zoom meeting.

Thereafter, that Bidder will be disqualified from further bidding on the work. 16. Rejection of Bids. Bids may be rejected if they show alterations of form, additions not called for, conditional bids, incomplete bids, erasures or irregularities of any kind. The Owner reserves the right to waive any irregularities in the bids as received and to reject any and all bids without qualification(s). More than one bid from an individual, firm or partnership, corporation or association, under the same or different names, will not be considered. Reasonable grounds for believing that a Bidder is interested in more than one such bid may cause the rejection of all bids in which said Bidder is interested. Bids in which prices are obviously unbalanced (as determined by Owner) may be rejected. Bids submitted without a Proposal Guaranty, per NCTCOG’s Item 102.5 of the Standard Specifications for Public works will be rejected. Bids with more than 575 Calendar Days for the time of completion will be rejected. 1-14 17. Bids to Remain Subject to Acceptance. All Bids will remain subject to acceptance for ninety (90) calendar days after the day of the Bid opening, but the Owner may, in its sole discretion, release any Bid prior to that date. 18. Contract Time. 18.1 The time of completion of the project will be set through the bidding technique used in the Proposal Form. A more detailed explanation of the bidding technique and completion time is given in Item 1.6 of the Specific Project Requirements (Section 4). Completion time will be a significant factor in the awarding of a contract for this project. 18.2 Prior to the issuance of the Notice to Proceed by the Owner, the Contractor shall submit a detailed Progress and Schedule chart to the Owner for approval. 18.3 Extension of the contract time shall be based on a Change Order or written amendment as specified in Item 108.8 of the General Provisions. 19. Award of Contract. 19.1 For the purpose of award, each bid submitted shall consist of: Base Bid (A) = The correct summation of the products of the estimated quantities shown in the proposal, multiplied by their bid unit prices. Time Bid (B) = (CD x Daily Value) = the product of the total number of calendar days (CD) provided by the Contractor and the Daily Value established by the Owner. For the purposes of this Contract, the Daily Value is $1,500.00. The lowest evaluated bid (Total Bid) will be determined by the Owner as the lowest sum of the Base Bid (A) plus the Time Bid (B) according to the following formula: Total Bid = Base Bid (A) + Time Bid (B) Time Bid (B) from the preceding formula will not be used to determine the final payment to the Contractor. All payments will be based on actual quantities and bid unit prices. The Owner desires to expedite construction on this contract to minimize the inconvenience to the traveling public and to reduce the time of construction. In order to achieve this, an incentive/liquidated damages provision is established for this contract. The total incentive payment shall not exceed $600,000.00. A more detailed explanation of the incentive/liquidated damages provision is given in Item 20 (below). 1-15 19.2 The Owner reserves the right to reject any and all Bids, to waive any and all formalities except for the time of submission of the Bid and to negotiate contract terms with the Successful Bidder. The Owner also reserves the right to reject all nonconforming, non- responsive, unbalanced or conditional Bids. Also, the Owner reserves the right to reject the Bid of any Bidder if the Owner believes that it would not be in the best interest of the Project to make an award to that Bidder, whether because the Bid is not responsive or the Bidder is unqualified or has doubtful financial ability or fails to meet any other pertinent standard or criteria established by the Owner. Discrepancies in the multiplication of units of Work and unit prices will be resolved in favor of the unit prices. Discrepancies between the indicated sum of any column of figures and the correct sum thereof will be resolved in favor of the correct sum. 19.3 In evaluating Bids, the owner will consider the qualifications of the Bidders, whether or not the Bids comply with the prescribed requirements, and such alternates, unit prices, and other data, as may be requested in the Bid form or prior to the Notice of Award. Time of completion will be a consideration in the award of the bid. 19.4 The Owner may consider the qualifications and experience of any Subcontractors, Suppliers, or other persons or organizations proposed for those portions of the Work as to which the identity of Subcontractors, Suppliers, and other persons and organizations must be submitted as requested by the Owner. The Owner also may consider the operating costs, maintenance requirements, performance data and guarantees of major items of materials and equipment proposed for incorporation in the Work when such data is required to be submitted prior to the Notice of Award. 19.5 The Owner may conduct such investigations as the Owner deems necessary to assist in the evaluation of any Bid and to establish the responsibility, qualifications and financial stability of Bidders, proposed Subcontractors, Suppliers and other persons and organizations to perform and furnish the Work in accordance with the Contract Documents to the Owner's satisfaction within the prescribed time. 19.6 If contract is to be awarded, it will be awarded to the lowest and best qualified Bidder whose evaluation by the Owner indicates to the Owner that the award will be in the best interests of the Project. 19.7 If the contract is to be awarded, the Owner will give the Successful Bidder a Notice of Award within ninety (90) calendar days after the date of the Bid opening. 20. Incentive/Liquidated damages. The Owner desires to expedite construction on this contract to minimize the inconvenience to the traveling public and to reduce the time of construction. In order to achieve this, an incentive/liquidated damages provision is established for this contract. The total incentive payment shall not exceed the amount listed below. However, there shall be no maximum liquidated damages. 1-16 20.1 Time of Completion. The maximum time of completion that will be allowed for the construction of South Royal Lane From W Sandy Lake Road to Highway 635 is 575 calendar days. A contract time bid of more than 575 days will be considered nonresponsive and, therefore, rejected. 20.2 Liquidated Damages. Failure to complete construction within the established number of calendar days, plus any additional calendar days granted, will result in liquidated damages being assessed for every calendar day in excess of the stated number. 20.3 Credit for Completion of Work Ahead of Time. Should the Contractor complete construction under the number of calendar days specified in the contract, a credit in the amount of the incentive per calendar day (equal to the liquidated damage rate) for the number of calendar days under the number stipulated in the proposal, plus any additional ca lendar days that may be granted. This credit will be added to the money due or to become due the Contractor under the contract. 20.4 Contract Completion. Contract Completion will be defined as occurring when all work shown in the plans and required under the contract has been completed and accepted by the Owner. Liquidated damages of $1,500 per calendar day shall also apply for any work that exceeds the total number of contract calendar days (“Original Contract Time” plus any additional days granted by change order). There is no maximum for liquidated damages. Additional provisions for the incentive/liquidated damages are set forth in Item 1.6 of the Specific Project Requirements (Section 4). 20.5 Maximum Incentive. The maximum incentive available is $600,000. 21. Execution of Agreement.

The Calendar day count for the project shall commence within ten (10) calendar days after the date of the Notice to Proceed or when the contractor begins work, whichever occurs first. 25. Sales Tax. The bidder shall not include or provide for sales tax on tangible personal property to be incorporated into the project. In order to be exempt from the sales tax on such tangible personal property, the contract shall separate and provide separate charges for materials to be incorporated into the project from charges for labor. The City will provide the Contractor with an exemption certificate for the materials. The contractor is expected to issue a resale certificate in lieu of paying a sales tax at the time of purchase. The bidder shall show the cost of materials to be incorporated into the contract (tangible personal property) in the space provided on the bid form. The successful bidders bid form will be used to develop a separated contract and will determine the extent of the tax exemption. Upon execution of the construction contract, the successful bidder shall provide a per item breakdown of: a) materials incorporated into the project; and b) labor, equipment, supervision and materials not incorporated into the project. 26. Silence of Specification. The apparent silence of these specifications as to any detail or to the apparent omission from it of a detailed description concerning any point, shall be regarded as meaning that only the best commercial practices are to prevail. All interpretations of these specifications shall be made on the basis of this statement by Owner or their authorized representative. 27. Change Orders.

It is still possible, however, for a contractor to make tax-free purchase of tangible personal property, which will be incorporated into and become part of a City construction project through the use of a "separated contract" with the City. A "separated contract" is one, which separates charges for materials from charges for labor. Under such a contract, the contractor becomes a "seller" of those materials, which are incorporated into the project, such as bricks, lumber, concrete, paint, etc. The contractor issues a resale certificate in lieu of paying the sales tax at the time such items are purchased. The contractor then receives an exemption certificate from the city for those materials. (This procedure may not be used, however, for materials, which do not become a part of the finished product. For example, equipment rentals, form materials, etc. are not considered as becoming "incorporated" into the project). Utilization of this "separated contract" approach eliminates the need for bidders to figure in sales tax for materials, which are to be incorporated into the project. The successful bidder's bid form will be used to develop the "separated contract" and will determine the extent of the tax exemption. Upon execution of the construction contract, the CONTRACTOR shall furnish a breakdown (per item) of: 1) materials incorporated into the project; and 2) labor, equipment, supervision and materials not incorporated into the project.” ITEM 107.19 - PROTECTION OF WORK AND OF PERSONS AND PROPERTY SC-107.19.2.1 Add the following new Item 107.19.2.1 immediately after Item 107.19.2: “107.19.2.1 Should CONTRACTOR cause damage to the work or property of any separate contractor at the site, or should any claim arise out of CONTRACTOR's, OWNER’s, ENGINEER’s, Consulting Engineer’s or any other person’s actions, CONTRACTOR shall promptly attempt to settle with such other contractor by agreement, or to otherwise resolve the dispute by 3-6 Standard Specifications Supplementary Conditions arbitration or at law. CONTRACTOR shall, to the fullest extent permitted by Laws and Regulations, indemnify and hold OWNER, ENGINEER and Consulting Engineer harmless from and against all claims, damages, losses and expenses (including, but not limited to, fees of engineers, architects, attorneys and other professionals and court and arbitration costs) arising directly, indirectly or consequentially out of any action, legal or equitable, brought by any separate contractor against OWNER, ENGINEER or Consulting Engineer to the extent based on a claim arising out of CONTRACTOR'S performance of the Work. Should a separate contractor cause damage to the work or property of CONTRACTOR or should the performance of work by any separate contractor at the site give rise to any other claim, CONTRACTOR shall not institute any action, legal or equitable, against OWNER, ENGINEER or Consulting Engineer or permit any action against any of them to be maintained and continued in its name or for its benefit in any court or before any arbiter which seeks to impose liability on or to recover damages from OWNER, ENGINEER or Consulting Engineer on account of any such damage or claim. If CONTRACTOR is delayed at any time in performing or furnishing Work by any act or neglect of a separate contractor and OWNER and CONTRACTOR are unable to agree as to the extent of any adjustment in Contract Time attributable thereto, CONTRACTOR may make a claim for an extension of time in accordance with Item 108.8. An extension of the Contract Time shall be CONTRACTOR's exclusive remedy with respect to OWNER, ENGINEER and Consulting Engineer for any delay, disruption, interference or hindrance caused by any separate contractor.” ITEM 107.23 – EXISTING STRUCTURES, FACILITIES AND APPURTENANCES SC-107.23.2.1 Add the following new Item 107.23.2.1 immediately after Item 107.23.2: “107.23.2.1 Existing Utilities and Sewer Lines: The CONTRACTOR shall be responsible for the locating and protection of all existing utilities or service lines crossed or exposed by the construction operations. Where existing utilities or service lines are cut, broken or damaged, the CONTRACTOR shall replace the utilities or service lines with the same type of original construction, or better, at his own cost and expense. This includes any and all irrigation systems, whether or not they are identified on the plans. If it is necessary to change or move the property of any owner or of a public utility, such property shall not be moved or interfered with until authorized by the ENGINEER. The right is reserved to the owner of any public utility to enter upon the limits of the project for the purpose of making such changes or repairs of their property that may be made necessary by the performance of this contract.” 3-7 Standard Specifications Supplementary Conditions ITEM 108.1 – PROGRESS SCHEDULE SC-108.1 Amend the first sentence of Item 108.1 by adding the following sentence: “Refer to Specific Project Requirements for additional schedule requirements.” ITEM 108.3 - OTHER CONTRACTORS; OBLIGATION TO COOPERATE SC-108.3 Delete the last sentence of the second paragraph of Item 108.3 and substitute the following in lieu thereof: "In such event, CONTRACTOR shall be entitled to an extension of working time only for unavoidable delays verified by the ENGINEER, as provided in Item 108.8; however, no increase in the contract price shall be due the CONTRACTOR." Insert the following sentence at the end of the second paragraph of Item 108.3: "The ENGINEER shall coordinate such other work with the CONTRACTOR and schedule events to minimize delay caused to the CONTRACTOR.

This waiver, release and acknowledgement of satisfaction shall be all-inclusive and absolute, save and except any routine OWNER final estimating quantity adjustments. Should the CONTRACTOR fail to actually complete the Contract and obtain final acceptance by the OWNER prior to expiration of the Original Contract Time, or should the CONTRACTOR, having timely completed the Contract and obtained final acceptance by the OWNER prior to expiration of the Original Contract Time, but having failed to timely request the incentive payment for any reason, and including but not limited to the CONTRACTOR choosing not to fully waive, release and acknowledge satisfaction as set forth in (2) above, the CONTRACTOR shall have no right to any payment whatsoever under this Article. Notwithstanding the CONTRACTOR’s election or non-election of the incentive under this provision, the liquidated damages provision applies to all circumstances where the work in the Contract is not finally accepted by the Original Contract Time. Should the CONTRACTOR fail to complete the Contract on or before the expiration of the Original Contract Time, as adjusted in accordance with the provisions above, the OWNER shall deduct from the monies due the CONTRACTOR the Daily Value specified in the Contract Documents for each calendar day completion exceeds the Original Contract Time. This deduction shall be the liquidated damages for the CONTRACTOR’s failing to timely complete the Contract. This shall be strictly enforced. In the event the CONTRACTOR elects to exercise this incentive payment provision, should this provision conflict with any other provision of the Contract; the Contract shall be interpreted in accordance with this provision.

Apply markings during good weather unless otherwise directed. If markings are placed at Contractor option when inclement weather is impending and the markings are damaged by subsequent precipitation, the Contractor is responsible for all required replacement costs. 4.3.1. Type I Markings. Place the Type I marking after the sealer cures. Apply within the temperature limits recommended by the material manufacturer. Flush the spray head if spray application operations cease for 5 min or longer by spraying marking material into a pan or similar container until the material being applied is at the recommended temperature. Apply on clean, dry pavements passing the moisture test described in Section 666.4.1., “General,” and with a surface temperature above 50°F when measured in accordance with Tex-829-B. 5.3.1.1. Non-Profile Pavement Markings. Apply Type I non-profile markings with a minimum thickness of:  0.100 in. (100 mils) for new markings and retracing water-based markings on surface treatments involving Item 316, “Seal Coat,” 824 666  0.060 in. (60 mils) for retracing on thermoplastic pavement markings, or  0.090 in. (90 mils) for all other Type I markings. The maximum thickness for Type I non-profile markings is 0.180 in. (180 mils). Measure thickness for markings in accordance with Tex-854-B using the tape method. 5.3.1.2. Profile Pavement Markings. Apply Type I profile markings with a minimum thickness of:  0.060 in. (60 mil) for edgeline markings, or  0.090 in. (90 mil) for gore and centerline/no-passing barrier line markings. In addition, at a longitudinal spacing indicated on the plans, the markings must be profiled in a vertical manner such that the profile is transverse to the longitudinal marking direction. The profile must not be less than 0.30 in. (300 mil) nor greater than 0.50 in. (500 mil) in height when measured above the normal top surface plane of the roadway. The transverse width of the profile must not be less than 3.25 in., and the longitudinal width not less than 1 in., when measured at the top surface plane of the profile bar. The profile may be either a 1 or 2 transverse bar profile. When the 2 transverse bar profile is used, the spacing between the bases of the profile bars must not exceed 0.50 in. The above transverse bar width is for each 4 in. of line width. 5.3.2. Type II Markings. Apply on surfaces with a minimum surface temperature of 50°F. Apply at least 20 gal. per mile on concrete and asphalt surfaces and at least 22 gal. per mile on surface treatments for a solid 4 -in. line. Adjust application rates proportionally for other widths. When Type II markings are used as a sealer for Type I markings, apply at least 15 gal. per mile using Type II drop-on beads. 5.3.3. Bead Coverage. Provide a uniform distribution of beads across the surface of the stripe for Type I and Type II markings, with 40% to 60% bead embedment. 5.4. Retroreflectivity Requirements. When specified on the plans, Type I markings must meet the following minimum retroreflectivity values for edgeline markings, centerline or no passing barrier -line, and lane lines when measured any time after 3 days, but not later than 10 days after application:  White markings: 250 millicandelas per square meter per lux (mcd/m2/lx)  Yellow markings: 175 mcd/m2/lx 4.5. Retroreflectivity Measurements. Use a mobile retroreflectometer for projects requiring minimum retroreflectivity requirements to measure retroreflectivity for Contracts totaling more than 200,000 ft. of pavement markings, unless otherwise shown on the plans. For Contracts with less than 200,000 ft. of pavement markings or Contracts with callout work, mobile or portable retroreflectometers may be used at the Contractor’s discretion. 4.5.1. Mobile Retroreflectometer Measurements. Provide mobile measurements averages for every 0.1 miles unless otherwise specified or approved. Take measurements on each section of roadway for each series of markings (i.e., edgeline, center skip line, each line of a double line, etc.) and for each direction of traffic flow. Measure each line in both directions for centerlines on two-way roadways (i.e., measure both double solid lines in both directions and measure all center skip lines in both directions). Furnish measurements in compliance with Special Specification, “Mobile Retroreflectivity Data Collection for Pavement Markings,” unless otherwise approved. The Engineer may require an occasional field comparison check with a portable retroreflectometer meeting the requirements listed above to ensure accuracy. Use all equipment in accordance with the manufacturer’s recommendations and directions. Inform the Engineer at least 24 hr. before taking any measurements. A marking meets the retroreflectivity requirements if:  the combined average retroreflectivity measurement for a one-mile segment meets the minimum retroreflectivity values specified, and  no more than 30% of the retroreflectivity measurement values are below the minimum retroreflectivity requirements value within the one-mile segment. 825 666 The Engineer may accept failing one-mile segments if no more than 20% of the retroreflectivity measurements within that mile segment are below the minimum retroreflectivity requirement value. The one-mile segment will start from the beginning of the data collection and end after a mile worth of measurements have been taken; each subsequent mile of measurements will be a new segment. Centerlines with 2 stripes (either solid or broken) will result in 2 miles of data for each mile segment. Each centerline stripe must be tested for compliance as a stand-alone stripe. Restripe at the Contractor's expense with a minimum of 0.060 in. (60 mils) of Type I marking if the marking fails retroreflectivity requirements. Take measurements every 0.1 miles a minimum of 10 days after this second application within that mile segment for that series of markings. If the markings do not meet minimum retroreflectivity after 10 days of this second application, the Engineer may require removal of all existing markings, a new application as initially specified, and a repeat of the application process until minimum retroreflectivity requirements are met. 4.5.2. Portable Retroreflectometer Measurements. Take a minimum of 20 measurements for each 1-mi. section of roadway for each series of markings (i.e., edgeline, center skip line, each line of a double line, etc.) and direction of traffic flow when using a portable reflectometer. Measure each line in both directions for centerlines on two-way roadways (i.e., measure both double solid lines in both directions and measure all center skip lines in both directions). The spacing between each measurement must be at least 100 ft. The Engineer may decrease the mileage frequency for measurements if the previous measurements provide satisfactory results. The Engineer may require the original number of measurements if concerns arise. Restripe once at the Contractor's expense with a minimum of 0.060 in. (60 mils) of Type I marking material if the average of these measurements fails. Take a minimum of 10 more measurements after 10 days of this second application within that mile segment for that series of markings. Restripe again at the Contractor's expense with a minimum of 0.060 in. (60 mils) of Type I marking material if the average of these measurements fall below the minimum retroreflectivity requirements. If the markings do not meet minimum retroreflectivity after this third application, the Engineer may require removal of all existing markings, a new application as initially specified, and a repeat of the application process until minimum retroreflectivity requirements are met. 4.5.3. Traffic Control. Provide traffic control, as required, when taking retroreflectivity measurements after marking application. On low volume roadways (as defined on the plans), refer to the figure, “Temporary Road Closure” in Part 6 of the Texas Manual on Uniform Traffic Control Devices for the minimum traffic control requirements. For all other roadways, the minimum traffic control requirements will be as shown on the Traffic Control Plan (TCP) standard sheets TCP (3-1) and TCP (3-2). The lead vehicle will not be required on divided highways. The TCP and traffic control devices must meet the requirements listed in Item 502, “Barricades, Signs, and Traffic Handling.” Time restrictions that apply during striping application will also apply during the retroreflectivity inspections except when using the mobile retroreflectometer unless otherwise shown on the plans or approved. 4.6. Performance Period. All markings must meet the requirements of this specification for at least 30 calendar days after installation. Unless otherwise directed, remove pavement markings that fail to meet requirements, and replace at the Contractor’s expense. Replace failing markings within 30 days of notification. All replacement markings must also meet all requirements of this Item for a minimum of 30 calendar days after installation. 5.

The existing alignment currently consists of a four-lane divided concrete roadway overlaid with asphalt that is showing distress in multiple areas. It is understood that the new pavement will also be designed as a four-lane divided concrete thoroughfare with a center median. We understand that the same roadway grades and alignment will stay the same (no widening). 1.2 PURPOSE AND SCOPE The purposes of this geotechnical investigation were to: 1) explore the subsurface conditions at the site, 2) provide boring logs that present subsurface conditions encountered including water level observations and laboratory test results, 3) provide comments on the presence and effect of expansive soils on the proposed roadway reconstruction, and 4) provide pavement subgrade preparation and concrete pavement section recommendations. This investigation was performed in accordance with AGG Proposal P22-0311E dated March 9, 2022. 2.0 FIELD INVESTIGATION The field investigation consisted of drilling eleven (11) test borings (Borings B-1 thru B-11) along the proposed pavement alignment. The test borings were drilled to depths of 10 feet below the existing ground surface. In addition, pavement cores were taken at each of the test boring locations prior to drilling. The pavement thickness at the core locations were measured and are reported on the Logs of Borings (Figures 2 thru 12). Photographs of the pavement cores are provided in the Appendix to this report. A truck-mounted auger drill rig was used to advance these borings and to obtain samples for laboratory evaluation. The borings were located at the approximate locations shown on the Plan of Borings (Figure 1). ALLIANCE GEOTECHNICAL GROUP DE22-089 PAGE 20 Undisturbed samples of cohesive soils were obtained at intermittent intervals with standard, thin-walled, seamless tube samplers. These samples were extruded in the field, logged, sealed, and packaged to protect them from disturbance and maintain their in-situ moisture content during transportation to our laboratory. The results of the boring program are presented on the Logs of Borings (Figures 2 thru 12). A key to the descriptive terms and symbols used on the logs are presented in Figure 13. 3.0 LABORATORY TESTING The laboratory tests were performed on representative samples of the soil to aid in classification of the soil materials. These tests included Atterberg limits tests, percent passing #200 sieve tests, moisture content tests and dry unit weight determinations. Hand penetrometer tests were performed on the soil samples to provide indications of the swell potential and the foundation bearing properties of the subsurface strata. The results of these tests are presented on the Logs of Borings (Figures 2 thru 12). To provide additional information about the swell characteristics of these soils at their in-situ moisture conditions, absorption swell tests were performed on selected samples of the clay soils (Figure 14). In addition, soluble sulfate testing was performed on selected samples (Figure 15). Lime series tests were performed to determine optimum amount of lime for stabilization (Figure 16). 4.0 SITE AND SUBSURFACE CONDITIONS 4.1 GENERAL SITE CONDITIONS The project consists of reconstructing approximately 10,300 linear feet of Royal Lane from West Sandy Lake Road to Interstate 635 in Coppell, Texas. The existing pavement is in poor to fair condition with many areas previously being patched. See Plan of Borings (Figure 1) for site location and aerial view. 4.2 SUBSURFACE CONDITIONS Subsurface conditions encountered in the borings, including descriptions of the various strata and their depths and thickness, are presented on the Boring Logs. Note that depth on all borings refers to the depth from the existing grade or ground surface present at the time of the investigation. Boundaries between the various soil types are approximate. ALLIANCE GEOTECHNICAL GROUP DE22-089 PAGE 30 4.3 SITE GEOLOGY As shown on the Dallas Sheet of the Geologic Atlas of Texas, the site is located in an area underlain by Terrace Deposits over the Eagle Ford Shale Formation. The Eagle Ford Formation typically consists of interbedded layers of clay, weathered clay shale and shale. Soils derived from this formation are typically highly plastic clays exhibiting a high shrink/swell potential with variations in moisture content. These Eagle Ford shaley clay soils typically have very high soluble sulfate levels and are corrosive to buried concrete and metals. The overlying Terrace Deposits generally consist of gravel, sand, silt & clay. 4.4 GROUNDWATER CONDITIONS The borings were advanced using continuous flight auger methods. Advancement of the borings using these methods allows observation of the initial zones of seepage. Groundwater was not encountered within the test borings during drilling operations. For safety purposes, the borings were immediately backfilled upon completion prior to moving to the next boring location. Therefore, delayed water level readings were not obtained. It is not possible to accurately predict the magnitude of subsurface water fluctuations that might occur based upon short-term observations. The subsurface water conditions are subject to change with variations in climatic conditions and are functions of subsurface soil conditions and rainfall. 5.0 ANALYSIS AND SUBGRADE RECOMMENDATIONS 5.1 SOIL MOVEMENTS The subsurface exploration revealed the presence of highly expansive clay and shaley clay soils and moderately expansive sandy clay and silty clay soils. The clay and shaley clay soils will have a high to very high shrink/swell potential depending upon the soil moisture condition at the time of construction. The sandy clay and silty clay soils will have a low to moderate shrink/swell potential depending upon soil moisture conditions at the time of construction. Potential soil swell movements were performed using swell test results, pocket penetrometer readings, and moisture content tests to estimate the swell potential of the soil. The soils well movement values based upon the current soil moisture conditions at the boring locations have been estimated to be on the order of 2 to 3 inches beneath the existing pavement due to soil swelling (outside of the tree influenced areas). It should be noted that the clay soils outside of tree influenced areas were generally in a moist to ALLIANCE GEOTECHNICAL GROUP DE22-089 PAGE 40 average moisture condition at the time of this investigation. If the clay soils were allowed to significantly dry prior to pavement construction, the potential soil swell heave could exceed 6 inches. The potential soil swell heave is estimated to exceed 6 inches at this time in tree influenced areas. There is a potential for over 4 inches of differential soil swell heave between tree influenced areas and non-tree influenced areas. Note 1: If the trees are to be removed (or if they die due to reconstruction activities or for any other reason in the future) differential pavement movements would potentially occur as described above. Site preparation work would have to be performed if any tree is removed or killed during construction in order to lower the potential differential movements. If trees are to be removed and it is desired for the potential soil swell movements to be reduced, Alliance Geotechnical Group should be contacted to provide recommendations in order to reduce the movements to acceptable levels. Note 2: If the existing trees near the roadway remain, differential pavement settlements caused by ground shrinkage associated with moisture absorption by the root systems will occur as the trees continue to mature. In order to minimize future pavement settlements, it is recommended that root barriers be installed within tree influenced areas. An aborist should be consulted for recommendations related to root barriers. See Section 7.0 for tree effects. It is imperative that all cracks and joints in the pavement be sealed and maintained by routine sealing in order to minimize differential pavement deflections caused by soil swelling. It is also imperative that positive drainage be provided along the pavement edges to prevent ponding near the curb lines. 5.2 OPTIONAL SITE MODIFICATION TO REDUCE SOIL MOVEMENTS As mentioned above, differential upward pavement movements could occur at this site due to soil swelling. If the magnitude of differential pavement movement that exists at this site is not acceptable, site preparation work will have to be performed in order to lower the potential differential movements to acceptable levels. Moisture conditioning can be accomplished by excavation and moisture conditioning of the in-situ soils in compacted lifts. Recommendations can be provided upon request. 5.3 PROOFROOLING AND FILL PLACEMENT After removing the existing pavement and prior to placing any required fill, the exposed subgrade should be proofrolled. Proofrolling can generally be accomplished using a heavy (25 ton or greater total weight) pneumatic tired roller making several passes over the areas. The proofrolling operations should be performed under the direction of a qualified ALLIANCE GEOTECHNICAL GROUP DE22-089 PAGE 50 geotechnical engineer. Where soft or compressible zones are encountered, these areas should be removed to a firm subgrade. Any resulting void areas should be backfilled to finished subgrade in 8-inch compacted lifts as specified below. Note: A two-foot-thick layer of soft clay was encountered at Boring B-5. These soft clays should be over-excavated and removed as specified below. After completion of proofrolling, the ground surface should then be scarified to a depth of 8 inches and recompacted to levels specified below prior to placement of additional fill. We recommend that fill be placed in 8 inch horizontal lifts. Clay fill materials should be placed in 8 inch loose lifts and compacted to a minimum of 95 percent of the maximum density as determined by ASTM D 698. The clay soils should be compacted at optimum to +3% of its optimum moisture content. The upper eight (8) inches of pavement subgrade should be compacted to a minimum of 98% of ASTM D698 at -1% to +2% of optimum moisture. 5.4 CEMENT STABILIZED SOILS The subsurface materials anticipated at pavement subgrade will vary from lime-treated soils, clayey sand, base and cement treated base based upon the results of the test borings. These materials react with cement which serves to improve their support value and provide firm, uniform subgrade beneath the paving. A design mix could be performed to determine the optimum amount of cement required to achieve the required compressive strength for design (150 psi in 7 days). If a mix design is not performed, we recommend that a mininum of 8% of cement (58 pounds per square yard per 8-inch depth) be used for stabilization. A paddle agitated truck should be used to allow the cement to slurry to be applied uniformly. An acceptable gradation for pulveration (prior to cement treatment) would be 100% passing the 1-3/4” sieve, 85% passing the ¾” sieve, and 60% passing the No.4 sieve prior to spreading cement. Cement treatment, final mixing, shaping and compaction must be achieved within 2 hours. The cement stabilization should be performed in accordance with TxDOT Item 275 and Tex-120-E (including curing requirements). We recommend that the cement stabilization extend 2 feet beyond the edges of pavement in order to reduce effects of shrinkage during extended dry periods. The cement stabilized base should be compacted at -2% to +2% of optimum to a minimum of 98% of ASTM D698. Mixing, shaping and compaction must be achieved within 2 hours after adding cement. ALLIANCE GEOTECHNICAL GROUP DE22-089 PAGE 60 Note: Final gradation and fine grading must be completed prior to final compaction per TxDOT Item 275. The asphalt pavement overlay should be placed directly on top of hard undisturbed cement stabilized milled asphalt that has been continuously moisture cured. 5.5 FLEX BASE In lieu of performing cement stabilization, eight (8) inches of flex base could be used. The flex base should consist of crushed “Chico” stone and/or recycled crushed concrete base. The flex base should be compacted at optimum to +2% above optimum to a minimum of 95% of Modified Proctor density (ASTM D1557). The base materials should comply with TxDOT Item 247, Type D, Grade 1. After proofrolling, the upper eight (8) inches of pavement subgrade should be scarified and compacted prior to placing flex base. The upper eight (8) inches of the subgrade clay soils should be compacted at -1% to +2% of optimum moisture to a minimum of 98% of Standard Proctor density (ASTM D 698). If a rain event occurs prior to placing the flex base, the subgrade should be aerated and re-tested prior to flex base placement. 5.6 RECOMPACTED PAVEMENT SUBGRADE In lieu of performing cement stabilization or using flex base, the concrete pavement thickness should be increased and placed directly on compacted subgrade soils. The upper 8 inches of subgrade soil should be compacted at -1% to +2% of optimum moisture to a minimum of 98% of Standard Proctor density (ASTM D 698). Prior to placing fill and subgrade compaction, the subgrade should be proofrolled. Proofrolling should be performed in accordance with Section 5.3 of this report. Only on-site soil (comparable to the underlying subgrade soil) should be used for fine grading the pavement areas. After fine grading, the subgrade should again be watered if needed and re-compacted in order to re-achieve the moisture and density levels discussed above and provide a tight non-yielding subgrade. Sand should not be allowed for use in fine grading the pavement areas. Sand should be specifically prohibited beneath pavement areas during final grading since these more porous soils can allow water in flow, resulting in heave and strength loss of subgrade soils. The subgrade moisture content and density must be maintained until paving is completed. The subgrade should be watered just prior to paving to assure concrete placement over a moist ALLIANCE GEOTECHNICAL GROUP DE22-089 PAGE 70 subgrade. If a rain event occurs prior to paving, the subgrade should be aerated and re- tested prior to paving. 6.0 PAVEMENT SECTION RECOMMENDATIONS The pavement section recommendations provided below were designed based upon AASHTO Guide for Design of Pavement Structures using WinPAS 12 computer program and based upon the following design traffic data. We understand that the design traffic consists of average daily traffic volume (ADT) from Bethel Road to Interstate 635 of 16,713 vehicles with 7,893 traveling northbound and 8,820 traveling southbound. The percent heavy duty trucks is currently unknown. However, we understand that the surrounding area is mainly industrial and significant amounts of heavily loaded vehicles are anticipated. AGG has used 10% heavy vehicles for design purposes. This anticipated percentage is similar to what the City of Dallas uses for similar pavement classifications. If the percent of heavy vehicles is determined to be different than 10%, AGG should be contacted in order to revise the pavement recommendations. For the heavily loaded vehicles, we have assumed 25% buses and 75% 18-wheeler traffic. A summary of the inputs used in WinPAS are provided below: Design E 18’s: 20 year Design: 1,942,206 Initial Serviceability: 4.5 Terminal Serviceability: 2.5 Modulus of Rupture: 588 psi (4,000 psi concrete) Elasticity Modulus: 3,392,000 psi Effective k-value: 250 psi/in - cement-stabilization Effective k-value: 250 psi/in – crushed concrete flexbase Effective k-value: 50 psi/in – recompacted subgrade Reliability Level: 95% Standard Deviation: 0.39 Load Transfer J: 2.7 (adequate edge support) Drainage Coefficient: 1.0 Tables 1 presents the recommended pavement sections for the proposed pavement sections. ALLIANCE GEOTECHNICAL GROUP DE22-089 PAGE 80 TABLE 1 - RECOMMENDED PAVEMENT SECTIONS ROYAL LANE *4,000 psi (at 28 days) for machine finish. The concrete strength should be increased to 4,500 psi at 28 days for hand finish. A minimum 28-day flexural strength of 588 psi. Note: The above pavement sections are based upon adequate pavement edge support being provided. If adequate pavement edge support is not provided, the above pavement thicknesses should be increased by one (1) inch. Concrete quality will be important in order to produce the desired flexural strength and long- term durability. We recommend that the concrete have 5% entrained air plus or minus 1%. The concrete should be placed at a slump of 4 inches plus or minus 1 inch for hand pours and a slump of 2 inches plus or minus 1 inch for machine finish pours. Proper joint placement and design is critical to pavement performance. Load transfer at all joints and maintenance of watertight joints should be provided. Control joints should be sawed as soon as possible after placing concrete and before shrinkage cracks occur. All joints including sawed joints should be properly cleaned and sealed as soon as possible to avoid infiltration of water. Our previous experience indicates that joint spacing on 12 to 15-foot centers have generally performed satisfactorily. It is our recommendation that the concrete pavement be reinforced with a minimum of No. 4 bars placed on chairs on approximately 18−inch centers in each direction.

The soils at the site are active and differential heave within the paving areas will occur. The service life of paving may be reduced due to water infiltration into subgrade soils through heave induced cracks in the paving section. This will result in softening and loss of strength of the subgrade soils. A regular maintenance program to seal paving cracks will help prolong the service life of the paving. The life of the pavement can be increased with proper drainage. Areas should be graded to prevent ponding adjacent to curbs or pavement edges. Granular backfill materials, which could hold water behind the curb, should not be permitted. Compacted clay soils should be used behind the curb. Flat pavement grades should be avoided. 7.0 TREE EFFECTS Medium to large mature trees are present along the proposed alignment with drip lines that extend near or over the pavements. The roots of mature trees absorb large amounts of moisture from the supporting soils to depths of over 15 feet. The lateral limits of tree root influence extend at least 5 feet beyond the unpruned drip line (and to much greater distances when the ground beneath the drip lines is paved and/or if multiple trees are present in the area which occurs at this site). To reduce future settlement after construction, root barriers and/or irrigated tree wells should be considered. An arborist or landscape architect should be contacted regarding the required depth of the root barrier and whether or not this is a viable solution. 8.0 FIELD SUPERVISION AND DENSITY TESTING Field density and moisture content determinations should be made on each lift of fill with a minimum of 1 test per 100 linear feet for the roadways. Supervision by the field technician and the project engineer is required. Some adjustments in the test frequencies may be required based upon the general fill types and soil conditions at the time of fill placement. Many problems can be avoided or solved in the field if proper inspection and testing services are provided. It is recommended that all site and subgrade preparation and pavement placement be monitored by a qualified engineering technician. Density tests should be performed to verify compaction and moisture content of any earthwork. Inspection should be performed prior to and during concrete placement operations. ALLIANCE GEOTECHNICAL GROUP DE22-089 PAGE 10 0 9.0 LIMITATIONS The professional services, which have been performed, the findings obtained, and the recommendations prepared were accomplished in accordance with currently accepted geotechnical engineering principles and practices. The possibility always exists that the subsurface conditions at the site may vary somewhat from those encountered in the test borings. The number and spacing of test borings were chosen in such a manner as to decrease the possibility of undiscovered abnormalities, while considering the nature of loading, size, and cost of the project. If there are any unusual conditions differing significantly from those described herein, Alliance Geotechnical Group should be notified to review the effects on the performance of the proposed recommendations. The recommendations given in this report were prepared exclusively for the use of client and their client and consultants. The information supplied herein is applicable only for the design of the previously described development to be constructed at locations indicated at this site and should not be used for any other structures, locations, or for any other purpose. We will retain the samples acquired for this project for a period of 30 days subsequent to the submittal date printed on the report.

Results of tests conducted on samples recovered are reported on the boring logs. Abbreviations used are: DD = natural dry density (pcf) LL = liquid limit (%) MC = natural moisture content (%) PL = plastic limit (%) Uncon.= unconfined compression (tsf) PI = plasticity index P.Pen.= hand penetrometer (tsf) -200 = percent passing #200 4. Rock Cores REC = (Recovery) sum of core sample recovered divided by length of run, expressed as percentage. RQD = (Rock Quality Designation) sum of core sample recovery 4" or greater in length divided by the run, expressed as percentage. FIGURE:13 Alliance Geotechnical Group, Inc. SWELL TEST RESULTS PROCEDURE: 1. The subject sample is placed in a confined ring. Then, the design load (including overburden) is applied to the sample. 2. The confined ring with the sample is then submerged with free water with surfactant and allowed to swell completely. 3. Once the swell movement stabilized, the design load was removed and the sample was retrieved for final moisture content determination.
