The contract is for the design of the roundabout at CR 34/17 and the bridge replacement for BR34/17Q. The BOCC awarded the contract to Atkins Realis on March 4, 2026. The Tyler reference number is 2026-0457. The OnBase Contract ID is 10441. The contract is for an amount not to exceed $3,602,216.00. Public Works has included the project in its 2026 budget. I will attend the BOCC meeting to answer any questions the BOCC may have.

The procurement process followed the Qualifications- Based Selection (QBS) method as permitted by County Code. The intersection at WCR 34 and WCR 17 is currently ranked as one of the most hazardous intersections in the county due to poor sight distance and other safety concerns. Additionally, Bridge 34/17A over the St. Vrain River is a poorly rated bridge in need of replacement. To minimize disruption to Weld County residents, Public Works proposes replacing both the intersection and the bridge concurrently. The latest CIP shows the construction of the project to be started in late 2028 or early 2029. To meet this timeline, design work—including engineering, right-of-way (ROW) acquisitions, and utility relocations—must begin quickly. Public Works received and scored proposals from 6 design firms. Out of the six proposals received: • 2 firms were deemed to be non-responsive • 1 firm withdrew from the process • 3 firms had their RFPs reviewed and scored Atkins Realis achieved the highest score throughout the evaluation process. Scoring results are attached for reference. Staff would like to proceed to the negotiation phase of this procurement with Atkins Realis. What options exist for the Board? • Option 1: Authorize Public Works to negotiate with Atkins Realis to define the scope of work and establish a design cost. • Option 2: Direct Public Works to continue searching for a more qualified consultant, which will delay the project schedule. Consequences: If Option 1 is approved, Public Works can maintain the current project schedule. If Option 2 is chosen, the design phase will be delayed, which may cascade into delays for ROW acquisitions, utility relocations, and construction. Impacts: Project delays will likely increase overall construction costs, resulting in a higher financial burden on Weld County taxpayers. Costs (Current Fiscal Year / Ongoing or Subsequent Fiscal Years): Design costs typically range from 10%to 15%of construction costs. With an estimated construction cost of$25 million, the design budget is expected to fall between $2.5 million and $3.75 million. Public Works will negotiate with Atkins Realis to ensure the design scope and budget remain within this range and will update the project budget annually during the design phase. Recommendation: Public Works recommends that the Board authorize contract negotiations with Atkins Realis under the QBS process. Atkins Realis has been a reliable partner on multiple projects over the past decade, consistently delivering designs within agreed scope and budget. They also provide strong support during ROW acquisition, utility relocation, and construction phases. Support Recommendation Schedule Place on BOCC Agenda Work Session Other/Comments: OPOP Perry L.

The County in no way warrants that the above-required minimum insurer rating is sufficient to protect the Contractor from potential insurer insolvency. Required Types of Insurance Workers'Compensation and Employer's Liability Insurance as required by state statute, covering all of the Contractor's employees acting within the course and scope of their employment. The policy shall contain a waiver of subrogation against the County. This requirement shall not apply when a Contractor or subcontractor is exempt under Colorado Workers' Compensation Act., AND when such Contractor or subcontractor executes the appropriate sole proprietor waiver form.

Upon County's request, Contractor shall provide to County, for examination, a policy, endorsement, or other proof of insurance as determined in County's sole discretion. Provided information for examination shall be considered confidential, and as such, shall be deemed not subject to Colorado Open Records Act (CORA) disclosure. All insurers must be licensed or approved to do business within the State of Colorado, and unless otherwise specified, all policies must be written on a per occurrence basis.

Each insurance policy required by this Agreement must be in effect at or prior to commencement of work under this Agreement and remain in effect for the duration of the project, and for a longer period of time if required by other provisions in this Agreement. Failure to maintain the insurance policies as required by this Agreement or to provide evidence of renewal is a material breach of contract. All certificates and any required endorsement(s) shall be sent directly to the County Department Representative's Name and Address. The project/contract number and project description shall be noted on the Certificate of Insurance. The County reserves the right to require complete, certified copies of all insurance policies required by this Agreement at any time, and such shall also be deemed confidential. Any modification or variation from the insurance requirements in this Agreement shall be made by the County Attorney's Office, whose decision shall be final. Such action will not require a formal contract amendment but may be made by administrative action. 15. Additional Insurance Related Requirements. The County requires that all policies of insurance be written on a primary basis, non-contributory with any other insurance coverages and/or self-insurance carried by the County. The Contractor shall advise the County in the event any general aggregate or other aggregate limits are reduced below the required per occurrence limit. At their own expense, the Contractor will reinstate the aggregate limits to comply with the minimum requirements and shall furnish the County with a new certificate of insurance showing such coverage is in force. Commercial General Liability Completed Operations coverage must be kept in effect for up to three (3) years after completion of the project. Contractor's Professional Liability (Errors and Omissions) policy must be kept in effect for up to three (3) years after completion of the project. Certificates of insurance shall state that on the policies that the County is required to be named as an Additional Insured, the insurance carrier shall provide a minimum of 30 days advance written notice to the County for cancellation, non-renewal, suspension, voided, or material changes to policies required under this Agreement. On all other policies, it is the Contractor's responsibility to give the County 30 days' notice if policies are reduced in coverage or limits, cancelled or non-renewed. However, in those situations where the insurance carrier refuses to provide notice to County, the Contractor shall notify County of any cancellation, or reduction in coverage or limits of any insurance within seven (7) days or receipt of insurer's notification to that effect. The Contractor agrees that the insurance requirements specified in this Agreement do not reduce the liability Contractor has assumed in the indemnification/hold harmless section of this Agreement. Failure of the Contractor to fully comply with these requirements during the term of this Agreement may be considered a material breach of contract and may be cause for immediate termination of the Agreement at the option of the County. The County reserves the right to negotiate additional specific insurance requirements at the time of the contract award. 16. Subcontractor Insurance. Contractor hereby warrants that all subcontractors providing services under this Agreement have or will have the above-described insurance prior to their commencement of the Work, or otherwise that they are covered by the Contractor's policies to the minimum limits as required herein. Contractor agrees to provide proof of insurance for all such subcontractors upon request by the County. 17. No limitation of Liability. The insurance coverages specified in this Agreement are the minimum requirements, and these requirements do not decrease or limit the liability of Contractor. The County in no way warrants that the minimum limits contained herein are sufficient to protect the Contractor from liabilities that might arise out of the performance of the Work under by the Contractor, its agents, representatives, employees, or subcontractors. The Contractor shall assess its own risks and if it deems appropriate and/or prudent, maintain higher limits and/or broader coverages. The Contractor is not relieved of any liability or other obligations assumed or pursuant to the Contract by reason of its failure to obtain or maintain insurance in sufficient amounts, duration, or types. The Contractor shall maintain, at its own expense, any additional kinds or amounts of insurance that it may deem necessary to cover its obligations and liabilities under this Agreement. 18. Certification of Compliance with Insurance Requirements. The Contractor stipulates that it has met the insurance requirements identified herein. The Contractor shall be responsible for the professional quality, technical accuracy, and quantity of all services provided, the timely delivery of said services, and the coordination of all services rendered by the Contractor and shall, without additional compensation, promptly remedy and correct any errors, omissions, or other deficiencies. 19. Mutual Cooperation. The County and Contractor shall cooperate with each other in the collection of any insurance proceeds which may be payable in the event of any loss, including the execution and delivery of any proof of loss or other actions required to affect recovery. 20. Indemnity. The Contractor shall indemnify, hold harmless and, not excluding the County's right to participate, defend the County, its officers, officials, agents, and employees, from and against any and all liabilities, claims, actions, damages, losses, and expenses including without limitation reasonable attorneys'fees and costs, (hereinafter referred to collectively as "claims") for bodily injury or personal injury including death, or loss or damage to tangible or intangible property caused, or alleged to be caused in whole or in part by the negligent or willful acts or omissions of Contractor or any of its owners, officers, directors, agents, employees or subcontractors. This indemnity includes any claim or amount arising out of or recovered under the Workers' Compensation Law or arising out of the failure of such contractor to conform to any federal, state, or local law, statute, or ordinance, rule, regulation, or court decree. It is the specific intention of the parties that the County shall, in all instances, except for claims arising solely from the negligent or willful acts or omissions of the County, be indemnified by Contractor from and against any and all claims. It is agreed that Contractor will be responsible for primary loss investigation, defense, and judgment costs where this indemnification is applicable. In consideration of award of this contract, the Contractor agrees to waive all rights of subrogation against the County, its officers, officials, agents, and employees for losses arising from the work performed by the Contractor for the County. The Contractor shall be fully responsible and liable for any and all injuries or damage received or sustained by any person, persons, or property on account of its performance under this Agreement or its failure to comply with the provisions of the Agreement. A failure of Contractor to comply with these indemnification provisions shall result in County's right but not the obligation to terminate this Agreement or to pursue any other lawful remedy. 21. Non-Assignment. Contractor may not assign or transfer this Agreement or any interest therein or claim thereunder, without the prior written approval of County.

Term. The term of this Agreement begins upon the date of the mutual execution of this Agreement and shall continue through and until Contractor's completion of the responsibilities described in the attached Exhibits. Both of the parties to this Agreement understand and agree that the laws of the State of Colorado prohibit County from entering into Agreements which bind County for periods longer than one year.

On insurance policies where Weld County is named as an additional insured, the County shall be an additional insured to the full limits of liability purchased by the Contractor even if those limits of liability are in excess of those required by this Contract. Solicitation#B2500142 Page 29 Each insurance policy required by this Agreement must be in effect at or prior to commencement of work under this Agreement and remain in effect for the duration of the project, and for a longer period of time if required by other provisions in this Agreement.

However, in those situations where the insurance carrier refuses to provide notice to County, the Contractor shall notify County of any cancellation, or reduction in coverage or limits of any insurance within seven (7) days or receipt of insurer's notification to that effect. The Contractor agrees that the insurance requirements specified in this Agreement do not reduce the liability Contractor has assumed in the indemnification/hold harmless section of this Agreement. Failure of the Contractor to fully comply with these requirements during the term of this Agreement may be considered a material breach of contract and may be cause for immediate termination of the Agreement at the option of the County. The County reserves Solicitation#B2500142 Page 30 the right to negotiate additional specific insurance requirements at the time of the contract award. 16. Subcontractor Insurance.

The Contractor shall assess its own risks and if it deems appropriate and/or prudent, maintain higher limits and/or broader coverages. The Contractor is not relieved of any liability or other obligations assumed or pursuant to the Contract by reason of its failure to obtain or maintain insurance in sufficient amounts, duration, or types.

This indemnity includes any claim or amount arising out of or recovered under the Workers' Compensation Law or arising out of the failure of such contractor to conform to any federal, state, or local law, statute, or ordinance, rule, regulation, or court decree.

The Contractor shall be fully responsible and liable for any and all injuries or damage received or sustained by any person, persons, or property on account of its performance under this Agreement or its failure to comply with the provisions of the Agreement.

Thank you!*** Company Name: Date of Signature Signature: Name: Title: Addendum #1 Date: December 16, 2025 CONTRACTOR QUESTIONS AND RESPONSES Question 1: Will all of the accesses off WCR 34 need to be maintained? Are there any accesses the County is considering closing, particularly as we approach the bridge location from the east and west? Answer 1: As we work through the design process we will determine if we can close any accesses. Prior to deciding to close accesses, a meeting with the affected landowner will have to occur prior the 30%design submittal. Decisions regarding accesses to close shall be complete by the 30% design submittal. Question 2: Is the County open to full closure of WCR 34 for the bridge construction or will it prefer a phased construction approach? Answer 2: We are anticipating that a full closure of CR 17 and CR 34 would be done. We are planning to construct the roundabout and the bridge concurrently so we only have to shut the road down once. For scheduling purposes, the consultant shall provide a phasing plant for construction assuming a full closure of the intersection and bridge. Question 3: The County's ultimate goal for the bridge replacement is to completely remove overtopping which will increase profile grade and bridge length? Answer 3: We will have to balance the overtopping with costs and what the floodplain analysis shows. We are anticipating that the bridge will have to be longer and higher to deal with overtopping and potential floodplain issues. A 1 D and a 2D floodplain model shall be completed to better represent the velocities and flooding limits. Question 4: Is the Saint Vrain Creek a low or high debris stream? Answer 4: Since the bridge is going to be located in an area with a streambed slope is relatively flat and the floodplain is wide, it is assumed the creek will be low debris. However, the Consultant will be responsible for actually determining the debris classification prior to the 30% design submittal. Question 5: Will the eastern tie in limits be based solely on the profile raise at the bridge? Or does the County have specific limits in mind beyond the minimum required to address other issues (slope flattening, pavement distress, etc.)? Answer 5: The eastern tie in has not been established at this time. It will likely be driven by the new bridge profile, bridge alignment, sight distance, etc. The eastern limits of the project shall be determined prior to the 30% design submittal. Question 6: Is there an active known utility mounted on the south side of the bridge? There is a conduit, but it looks damaged. Answer: It is unknown if the conduit on the bridge is currently active. Regardless of whether or not it is active, the new bridge will not have utilities hanging off of it. Question 7: We observed utility locate marking at the intersection and wanted to know if there is work other than this project planned in the area that we should be aware of. Answer 7: The CR 34/17 intersection is one of the most dangerous intersections in the County. In an effort to help with the safety issues,we are currently designing a conflict warning system that will be installed some time in 2026.The conflict warning system will be removed when we do the roundabout project. Question 8: Is the County planning to consolidate any access points within the project limits? Answer 8: The design consultant will be responsible for determining if it will be possible to consolidate accesses. During the design phase, current access points may be moved to eliminate unsafe accesses. Question 9: The property on the southwest corner has an old access that is now blocked off (which we think is great because the location feels unsafe!). Are there any conversations or commitments to the landowner the design teams will need to be aware of when developing initial layouts? Answer 9: The County has not reached out to any of the adjacent landowners at this point. It will be the responsibility of the design team to make contact with affected landowners (prior to 30%submittal). Question 10: There appears to be a potential sight distance issue on the west leg of the intersection. Are you aware of any crash history due to this? Or will it just be evaluated in the normal course of design? Answer 10: This intersection ranks as one of the problem areas for accidents in the County. Prior to the 30% design submittal, the Consultant shall address the potential sign distance issues. It is likely that the roundabout will have to moved to the north and west of the current intersection. Question 11: Where exactly is BR34/17A located? Answer 11: BR34/17A is located on CR 34 between CR 17 and CR 19.The bridge crosses the Saint Vrain Creek which is approximately 1,600 feet east of the CR 34/17 intersection. Question 12: Is a CDOT ROW permit required for this project? Answer 12: No, the project will not require a CDOT ROW permit. The RFP document has been revised to remove references to a CDOT ROW permit. Question 12: The RFP document states that emailed or hand delivered or emailed proposals will be accepted. Do the hand delivered copies have to be delivered by 10 am on January 9,2026? Answer 12: Emailed proposals are preferred. If you do not wish to submit an emailed proposal, you will need to hand deliver 5 hardcopies of your proposal to the Purchasing Department at 1301 North 17'h Ave by 10 a.m. on January 9. If you submit an email bid, the Purchasing Department will accept the 5 hardcopies until 4 p.m. on January 9th. Question 12: Can we submit maps and graphics on 11x17 sheets? Answer 12: Maps would be okay to submit on 11x17 sheets as long as there are no additional graphics on the page. If graphics or tables are included on the 11x17 sheet, the sheet will be counted as 2 pages. Question 13: Where do we need to include a discussion of our project experience in the proposal? Answer 13: The discussion regarding your experience should be included in the Scope of Proposal section of the response to the RFP. In fact, to ease the reviewers in scoring the submittals, it is recommended that your proposal be broken into the sections shown in Table 1 - Proposal Scoring Criteria. Question 14: Was an intersection safety study done on the CR 34/17 intersection? Answer 14: No, an intersection safety study was not done on the intersection However, the County has crash data Indicating the need for safety improvements at the intersection. Out of the available options available to choose from, the County has opted to go with a roundabout to increase the safety at the intersection. Question 15: What kinds of public information activities will the Consultant be responsible for? Answer 15: It is anticipated that the Consultant will be responsible for communicating with the affected landowners adjacent to the roundabout and the bridge. There may also be a need to write small update articles for the County's Public Information Officer (PIO) to post to our social media websites from time to time. Communication with the affected utilities as well as property owners will be required throughout the design phase. Question 16: Are the landowners aware of the scope of the project? Answer 16: The County has not communicated the full scope of the project to the landowners. The landowners are aware in general that a project is coming though. The selected Consultant will be responsible for getting landowner input before the submittal of the 30% design. Question 17:Will the Consultant be responsible for designing the connecting roadway between the bridge and the roundabout? Answer 17: Yes, the Consultant will be responsible for designing the roadway connecting the bridge and the roundabout.As described in the RFP, the roundabout will likely have to be shifted to the northwest to avoid impacts to the house on the southwest corner of the intersection, minimize impacts to the floodplain, and minimize disturbances to an above ground oil and gas facility in the northeast corner of the intersection. Question 18: What is the County anticipating for the project limits of design? Answer 18: The County is anticipating that the approach road design to the roundabout could extend up to 1/2 mile on the west, north, and south legs. The east leg of the roundabout will have to be designed from the roundabout to the bridge. The approach road east of the bridge will be dependent upon floodplain impacts and site distance issues. The east leg could extend up to 1/2 mile east of the bridge. Question 19: What is the schedule for completing the design, acquiring ROW, relocating utilities, and starting construction? Answer 19: It is anticipated that the design phase of the project will take approximately a year to complete. Below is a schedule that the County anticipates . • February 2026 to July 2026-0% to 30% design (See RFP for activities to be completed) • August 2026 to mid-November 2026-30%to 60% (See RFP for activities to be completed) • Mid-November 2026 to mid-May 2027-Start ROW acquisition and complete 95% design (See RFP for activities to be completed) • Mid May 2027 to late June 2027-Complete Ready for Construction design • Mid-May 2027 to mid-November 2027 - Complete ROW acquisition and start utility relocations • Mid-November 2027 to mid-November 2028-Complete utility relocations • Early December 2028- Bid construction work for the roundabout and bridge. • February 2029 to mid November 2029 -Construction of roundabout and bridge. Question 20: Are resumes counted in the 25 page limit? Answer 20: Yes, resumes are counted in the 25 page limit.

Scope of Proposal Understanding of Project Objectives AtkinsRealis brings proven experience in roundabout and bridge design,floodplain analysis and regulatory compliance,traffic engineering and phasing, right-of-way(ROW)acquisition,and utility coordination and relocation.The project is comprised of two primary elements: 1. WCR 34/WCR 17 Intersection Roundabout- Enhances traffic flow and safety by replacing the existing four-way stop with a single-lane roundabout.The design must carefully balance operational improvements with minimal disruption to surrounding properties.Specific goals include: •Improving traffic operations and safety through roundabout construction • Minimizing ROW acquisition impacts, particularly on the northeast and southwest parcels • Preserving existing irrigation infrastructure on the northeast and southeast properties • Coordinating access points for adjacent landowners 2. WCR 34 Widening and 34/17A Bridge Replacement-Replaces the aging and previously flood damaged bridge over St.Vrain Creek as well as upgrading WCR 34 to meet current County standards.Specific goals include: • Reconstructing WCR 34 to the County's standard width for a collector • Replacing the near-structurally deficient 34/17A bridge • Elevating the roadway profile to remove it from the St.Vrain Creek floodplain • Ensuring continued access to existing properties throughout the corridor AtkinsRealis Qualifications&Relevant Experience I-70 Floyd Hill to Veterans Memorial Tunnels,CDOT Region 1 AtkinsRealis is the engineer of record and lead designer for the approximately six mile reconstruction of I-70 from the Floyd Hill • :.a vailw interchange to the Veterans Memorial Tunnels(VMTs).With a programmed budget of$800 million,the project is being delivered through CM/GC alternative project delivery and is designed to address CDOT's most critical challenges related to -� ; safety,mobility,and travel time reliability.The reconstruction -"4r,'4t introduces a tolled express lane on westbound I-70 and completes the missing two miles of frontage road between US 6 and the 0. Hidden Valley/Central City interchanges.The project includes :: `'.r`.. roundabout improvements at the Homestead and Beaver Brook/ Floyd Hill interchanges,enhances the Clear Creek Greenway Trail, and incorporates two wildlife underpasses to improve habitat connectivity.Additional upgrades include on ramp and off ramp improvements, the rebuilding of more than 10,000 lineal feet of bridges,and the construction of over 18,000 lineal feet of ° complex retaining wall systems.The project integrates floodplain and river hydraulics,including four floodplain benches to support stream habitat and advanced hydraulic modeling to address bridge and wall scour,freeboard,and rafting revetments.

Both bridges use precast side-by-side box girder beams. The final design of the 51st Ave Bridge required minimizing the structure depth for the hydraulics of the Platte River.It has the shortest superstructure depth,providing the most freeboard for the 100- year flood elevation and the 10-foot vertical clearance at the South Platte River Trail.

Atkins Realis Western Roadways 4600 S Ulster St Denver, CO 80237 720.323.1251 RE: WCR 34/17 Roundabout and BR34/17A Bridge Replacement Project Dear Joe, Per your request,we are pleased to provide this revised proposal for Professional Land Surveying Services in support of the WCR 34/17 Roundabout and BR34/17A Bridge Replacement Project in Weld County, CO. Once awarded, this project is anticipated to begin in late February 2026 will consist of the following services: Scope of Work This project is located in Weld County, Colorado,at the intersection of Weld County Roads(WCR) 34 & 17. The objectives of this project are to improve WCR 34/17 roadways as they approach a proposed roundabout at the intersection, and to design a new bridge across the St. Vrain River which will be less susceptible to overtopping in the event of significant flooding events. The roadway project extends approximately one-half mile north,west, and south of the intersection as well as approximately 4,200 feet east of the intersection across the St. Vrain River. Additionally, approximately 2,640' (1,320' upstream, 1,320' downstream of bridge) of the St. Vrain River floodplain will be mapped for LOMR purposes. DEA tasks will consist of survey and flight control establishment, topographic mapping, Right-of-Way (R.O.W) support, ROW plan set generation and acquisition support. The project area shown below in Figure 1 shows the approximate limits for the roadway project in red and the approximate limits for the St.Vrain River floodplain mapping component in blue. Existing USGS LIDAR data will be used to tie into the remainder of the floodplain mapping project for LOMR purposes. 1600 Broadway Suite 800 Denver Colorado 80202 Telephone:720.946.0969 Facsimile: 720.946.0973 fft Figure 1 — Roadway/Floodplain Survey Limits . 1.; ..

Survey Control • DEA will establish a minimum of twenty(20)semi-permanent project/ground control points and fifteen (15) additional ground control points for aerial LIDAR data collection. • The horizontal datum for this project will be a Modified State Plane Coordinate System. • Elevations will be tied to the nearest NGS vertical benchmark on the NAVD88 datum. • DEA will prepare a roadway Survey Control Diagram depicting all found and set control, boundary, and ROW monumentation that will be incorporated into the ROW Plans. Page 2 of 7 Q 0 Right-of-Way / Boundary Survey • DEA will research deeds, land survey plats,subdivision plats, and other record documents to determine property boundaries and right-of-way. • DEA will search for and survey existing ROW monuments, property corners, and aliquot corners. • DEA will also conduct research into existing properties to ensure there are no gaps or overlaps between private property and Weld County ROW. • AtkinsRealis will order up to ten (10) title commitments while DEA will plot all easements and encumbrances as noted within each title commitment. • DEA's fee includes addressing four (4) rounds of comments at 30%, 60%, 95%, and IFC phases. Topographic Survey • DEA will perform a topographic survey (conventional and Small Unmanned Aerial Systems — sUAS) to accurately acquire the existing conditions of the project area within the limits of the project. • The survey will include, but is not limited to, all visible topographic features, property improvements, curb and gutter, asphalt paving, concrete driveways, concrete sidewalks, storm drainage improvements, structures, fences, buildings, and other relevant visible items as identified. • If fencing or other improvements prevent crews from accessing certain areas within the site limits, DEA will survey up to those improvements and include them in the base files with a note indicating the limitation or perform an aerial survey to obtain such features on private property. • DEA will conduct on-the-ground channel and floodplain cross-sections on the St. Vrain River from the FEMA cross-sections provided by client —four (4) upstream and three (3) downstream crossings from existing bridge are anticipated. • All other cross-sectional ground data for approximately 1,320' upstream and 1,320' downstream will be collected by sUAS means with no on-the-ground survey support provided. • DEA will conduct LOMR survey support according the FEMA LOMR Checklist. • DEA will provide survey staking (ROW, running line, cut depth, etc.)for the utilities, oil/gas facilities, and irrigation facilities that are to be relocated. Three (3) field trips, within which restaking of these features may occur, are anticipated. • DEA will as-built any relocated utility during construction and provide data to Client for their preparation of an As-Built Drawing. Page 3 of 7 C a • The topographic survey will be sufficient to create a 3D surface accurate to a one foot (1') minor and five foot (5') major contour interval with all visible planimetric data within the survey limits shown for design purposes. • Prepare a final survey in AutoCAD format showing all field information denoted above. • DEA will locate and survey wetland delineation markers as provided by Tiglas and add this information to our CAD base files • One (1) round of topographic survey revisions is assumed following project site visit.

AtkinsRealis- Baseline/Reference 2 GEG GRANITE ENGINEERING GROUP February 15,2025 Proposal No.25-302 Mr.Joseph Zufall,PE AtkinsRbalis 4600 South Ulster Street,Suite 1100 Denver,CO 80237 Subject: Proposal for Geotechnical Engineering Services WCR 34-17 Roundabout and Bridges Replacement Weld County,Colorado Dear Mr.Zufall, This proposal presents our project understanding,proposed scope of work,estimated schedule,estimated project cost,and fee schedule for providing geotechnical engineering services for the proposed round about at WCR 34-17 and bridges replacement on County Road 34/17A in Weld County,Colorado. Based on the preliminary information provided,it is anticipated that the proposed bridges will be a three (3)span structure over St.Vrain Creek,and a new three(3)span bridge over tributary areas east of the existing bridge.The bridge approaches will also be reconstructed within 1,000 feet on the east and 1,500 feet to the west where a new roundabout is planned at the intersection of WCR 24 and 17.Based on limited research,the proposed project is located in the Alluvium.These alluvium materials are expected to consist of sand and gravel. Scope of Work The scope of the preliminary geotechnical engineering services is to evaluate the subsurface conditions for the design and construction of the proposed bridge structure and approaches pavement. Based on our understanding of the project and assumptions,the proposed geotechnical scope of work for the project is presented below. 1. Arrange for underground utility locates within the vicinity of the proposed boring locations. A private utility locator is not anticipated nor is included in the proposed services. 2. Perform the subsurface exploration program as presented in the table below: Locations Number of Remark Borings Pavement Borings 42 Approximately 30 borings at the roundabout,each legs,and the area in the new ROW.6 borings between roundabout and the bridge,and 6 borings east of the bridge.Existing pavement will be cored and borings extended to 10 feet below surface. Bridge Structure over St.Vrain 4 Extend to 30 feet into bedrock.Bedrock estimated at Creek 60 feet below existing ground surface Bridge over Tributary Areas 4 Extend to 30 feet into bedrock. Bedrock estimated at 60 feet below existing ground surface Topsoil 12 Existing topsoil samples 3. Traffic Control will be provided by a traffic control contractor following approved MUTCD while performing the borings on the roadway.For the purpose of this scope and fee,it is planned Granite Engineering Group,Inc.1 1110 Elkton Dr.,STE B,Colorado Springs,CO 80907 1 Tel:719-716-9009 WCR 34-17 Roundabout and New Bridges Proposal No: 25-302 Weld County, Colorado 2-15-26 to perform all the bridge borings on the existing roadway.The borings for the pier locations of the bridge over St.Vrain Creek will be performed by coring through the existing bridge deck and perform the drilling on the existing bridge deck.The holes will be patched after the drilling is completed.The borings may be moved to the area outside of the existing bridge once the pier locations are decided and if access can be obtained. 4. The soil and rock samples will be collected using Shelby Tube,SPT or a California Sampler depending on the soil types encountered. A GEG representative will log the borings in the field and recover soil samples. 5. Borings will be backfilled with cuttings and granular materials at the completion of drilling. Borings performed on the existing pavement area will be patched with materials similar to the existing pavement surface.In sensitive areas where potential settlement from the backfill cannot happen,the borings will be backfilled with grout mixed on site. 6. Conduct laboratory testing on recovered samples as needed to classify the subsurface soils and rock to develop the geotechnical engineering design criteria. Laboratory testing is anticipated to include soil index testing,moisture content, swell tests,R-value test,proctor tests,consolidation test,and analytical testing. R-Value tests will be performed on each pavement borings,and one (1)composite at each leg of the roundabout.Samples from the bridge borings will be tested for gradation/hydrometer test to provide Dso value for scour analysis.The exact type and quantity of the testing will be established when the field exploration is completed and subsurface samples are obtained. 7. Provide an electronic copy of the draft geotechnical report. The report will include a description and results of the field and laboratory test programs,exploration location map,boring logs,a description of site conditions,recommendations for the bridge foundation system for the proposed bridge including skin friction and end bearing parameters,Lpile parameters for deep foundation design,pavement thickness design using CDOT M-E methods,and discussions of roadway embankment settlement and slope stability if applicable. 8. Provide final report addressing the review comments. Schedule We will notify UNCC to obtain site utility clearances once the Notice to Proceed(NTP)is provided. We anticipate that we can begin performing the field investigation within two(2)to three(3)weeks after clearance of the utilities provided that weather is permissible and drill rig is available.We estimate that the field drilling will take twelve(12)days to complete and approximately twenty(20)business days for laboratory testing to be completed. A draft geotechnical report will be available within 2 weeks after the laboratory testing is completed. The final report will be available within 5 business days after the review comments are received. Fee The estimated fee for the geotechnical engineering services is$158,481.00. The itemized fee is provided below: Field Exploration,Lab Testing and Report Item Estimated Cost Field Investigation Subcontracts $63,380.00 GEG Field and Geotechnical Lab $61,251.00 Office Engineering $26,440.00 Grout Backfill $7,410.00 Total= $158,481.00 Granite Engineering Group,Inc.11110 Elkton Dr.,STE B,Colorado Springs,CO 80907 I Tel 719-716-9009 2 WCR 34-17 Roundabout and New Bridges Proposal No: 25-302 Weld County, Colorado 2-15-26 The cost for our geotechnical engineering services will be billed on time and material basis. We will not exceed our estimated budget without prior notice and authorization from AtkinsRealis. Exclusions 1. As drilled survey locations of the borings will be provided by others. Boring location will be marked by us with paint or stakes at the time the borings are drilled. 2. Environmental investigation or analysis. We will perform these services in a manner consistent with the standard of care and skill ordinarily exercised by members of the profession practicing under similar conditions in the geographic vicinity and at the time the services will be performed. Therefore,no warranty or guarantee expressed or implied is part of the services offered by this proposal.

Figure 1 below shows the limits of the SUE Investigation depicted in a red polygon.The Client has requested that the SUE investigation include 0.5miles north,south,and west of the intersection,4,200 feet east of the intersection, and 200 feet outside of the ROW line. T2 UES, Inc. performed a preliminary utility investigation for the project limits and identified 10 utility owners. There are an estimated 62,000 feet of subsurface utilities within the limits of this SUE investigation.The estimated linear footage is based on the QLD investigation of the intersection and records collected during that QLD investigation. It is understood that the Client desires to comply with the requirements outlined in Colorado Revised Statutes,Title 9,Article 1.5 (CRS 9-1.5) and perform an ASCE/UESI/CI 38-22: Standard Guideline for Investigating and Documenting Existing Utilities compliant SUE investigation that is signed and sealed by a Professional Engineer.The T2 UES, Inc.team will utilize the ASCE/UESI/CI 38-22 standard for collecting and documenting the existing utilities and building a high-quality representation of the existing utilities. This process will include an iterative field investigation and drawings signed and sealed by a Professional Engineer licensed in Colorado in accordance with all the requirements outlined in the State Law. tiy, �� I i _ % fi,._ : Y Ail i. -- .' �,, ...f/ . 1:9: "17, :1 re...:„.144.._. .,,. ::1 1� ® , a. .. i• .11......-.................:e....... . •�a../ ' 1. , .. . .. collitiet; , 0 * • Learn more at T2ue.com I Page 2 T2 utility engineers Scope of Work a kiwa company WCR34 and WCR17 QLB Investigation_Rev4 PROJECT APPROACH T2 UES, Inc.'s general workflow to our approach is outlined below and includes weekly updates for the entire project team: 1. Perform records research. 2. Perform a geophysical investigation(field designating). 3. Perform a survey of utility appurtenances and markings placed by our designators. 4. Complete utility depictions as outlined in the ASCE/UESI/CI 38-22 standard. 5. QA/QC of our investigation's findings based on existing records and our fieldwork. 6. Review the investigation's findings with the design team and project stakeholders. 7. Coordinate and perform QLA test holes. 8. Provide documentation of the completed utility investigation findings—signed and sealed by a licensed engineer. ASCEIUESIICI 38-22 provides a nationally recognized standard guideline for collecting and documenting existing subsurface utility data. The quality level provides a professional opinion of the quality and reliability of the utility information.The four quality levels are as follows: • Quality Level D (QLD): Utility Quality Level D (QLD) information is determined primarily from the review and documentation of existing second-party information,such as utility records,historical project records,permits,verbal accounts,the existence of service, visual indicators,and/or One-Call markings,put into context with any other information the SUE Professional has in their possession during a Utility Investigation. • Quality Level C (QLC): Utility Quality Level C (QLC) information is determined by correlating underground Utility Segments from existing second-party information to observable and measurable visible Utility Features.QLC does not refer to the Utility Feature or portion of the visible Utility Segment. It refers to the unobservable portion of the Utility Feature or Utility Segment that connects to visible,typically aboveground or within an accessible vault,surveyed Utility Features. • Quality Level B (QLB): A Utility Quality Level B (QLB) may be assigned to a Utility Segment after the application of appropriate surface geophysical methods to identify the existence and approximate horizontal position of utilities (a Utility's "Designation"), followed by survey and documentation,review of available field and office data,and a final determination of the position for the Utility Segment or Utility Feature on the Deliverables.All aforementioned tasks are performed under the direct responsibility of the SUE Professional.The largest potential error source is usually the geophysical findings and results interpretation. • Quality Level A(QLA): Quality Level A(QLA) builds on QLB information by confirming the existence, exact locations,and other attributes of subsurface utility through the utility's exposure using safe excavating practices. QLA data are determined by physically exposing an unobservable utility feature or utility segment(essentially making it observable)and documenting its spatial extent and characteristics with high accuracy. Conventional accuracies shall be 0.1ft (30mm) vertical and 0.2ft (60 mm) horizontal for the measurements of the outside limits of the utility features or utility segment that is exposed.

T2 UES, Inc. shall conduct, document, stamp, and seal a Subsurface Utility Engineering (SUE) investigation of the project area to document existing utilities within the project limits.As part of the SUE investigation for this project,T2 UES, Inc.will work on the following tasks: QLBICID Investigation Utility Records Research • Submit a Subsurface Utility Engineering ticket to Colorado 811 to aid in the identification of Utility Owners that may have facilities on or be affected by the project. • Request,collect,and review applicable utility facility records available through Utility Owner(s),such as one-call notification,service maps, as-built drawings, standard drawings, service plats, construction plans from prior projects, local government or Agency permit exhibit drawings,and oral histories gained through interviews with Utility Owner officials and authorities. • Compile a list of all utility companies contacted for information. Note information received with contact information for each response and note non-response if applicable. Field Utility Investigation (Utility Designation) • Utilize appropriate surface geophysical techniques to determine the approximate horizontal position of utilities within the project area. Once designated (horizontally positioned),verified utilities are marked using appropriate pink paint and flagging,the standard industry color for temporary survey markings.Utilities type or ownership that the field investigation cannot confirm will be termed"unknown."T2 UES,Inc.will utilize equipment including pipe and cable locators(PCL),Ground Penetrating Radar(GPR),magnetometers,and detectable sondes. • If accessible, structures connected to gravity-fed systems will be opened, and inverts will be measured. Invert information and, where accessible, pipe size/material for the sewers will be collected at manholes/catch-basins from the surface and shown on the drawings accordingly.The alignment of the sewer pipes will be shown on the drawing based on a combination of record information received,results of the invert investigation,surveyed manholes/catch-basins,and professional judgment.If chambers are full of water or confined space entry is required,extra costs will be incurred and discussed with the Client in advance. • T2 UES,Inc.will hire a survey subconsultant to survey the utility designation marks and utility appurtenances referenced to the project survey controls.The results of this utility investigation and any survey work performed in conjunction with the investigation will be tied to the project datum specified by the client and existing survey grade control points provided to T2 UES,Inc. QA/QC and Professional Services • Generate and review permits and Maintenance of Traffic plans. • Review the field investigation documents and records collected for records research.Use professional judgment to assign quality levels and horizontal positions to subsurface utilities. • Consolidate and draft the collected field information in an AutoCAD and PDF deliverable using Weld County Standards. QLB/C/D Utility Investigation Assumptions. Exclusions, and Stipulations • T2 UES,Inc.cannot guarantee we will find all unknown,abandoned,retired,or inactive utilities. • Individual utility services to homes and buildings will include water,electricity,and natural gas,telephone,and CAN. • T2 UES, Inc.will request information from utility owners and private property owners within the project limits regarding the presence of any underground storage tanks(USTs),septic fields,thrust blocks,and cathodic protection systems.If any of these structures exist,they will be notated in the SUE model and the SUE plans. If there are any surface utility appurtenances found associated with these structures,they will be surveyed as a part of the utility survey. • T2 UES,Inc.will designate any control wires for landscape irrigation and will identify any sprinkler heads that are visible from the surface. Learn more at T2ue.com I Page 4 4/.. 1 2 utility engineers Scope of Work a kiwa company WCR34 and WCR17 QLB Investigation_Rev4 • Overhead utility lines will be shown as a singular line running pole to pole.We will attempt to identify both ownership&connections on the poles and incorporate this information into the plans using pole diagrams, images,and/or spreadsheets(or some combination thereof)as best suits this project and existing site conditions. • No butterfly diagrams or 3D modeling(with pipe networks)will be included in this scope. • The removal of Colorado 811 paint marks or designation marks is not included. • The degree of success of a ground-penetrating radar(GPR) investigation is based entirely on the soils'composition and the subsurface targets'depth and scale.Electrically less-conductive soils,such as quartz sands,typically allow for the detection of some utilities and/or their trenches at depths greater than 10 feet.Electrically conductive soils,such as clay,moist silt,or saline soils,typically preclude the investigation of targets deeper than three to six feet.Due to the unknown receptiveness of specific site soils to the passage of radar energy,conclusive results cannot be guaranteed from GPR. • Diagrams of the conduits within vaults are excluded. • No utility coordination,relocation design,or conflict analysis will be performed in this scope. • It is assumed there is no permit fee for work in Weld County right of way. QLA Investigation T2 UES, Inc. has estimated that up to 127 Quality Level A test holes will be required. The quantity of QLA test holes is based on Weld County's minimum test hole spacing requirements. Weld County also requires a test hole be performed at the edge of the road and in the center of the road for each roadway crossing. Below is a summary table outlining how T2 UES, Inc. arrived at 127 Test holes. T2 UES, Inc. will attempt to schedule multiple vac trucks and crews operating each day and will attempt to share traffic control setups to minimize traffic closures and control costs. Maximum Test Linear Number of Type of Utility Hole Spacing Feet of Roadway Quantity of Test Holes Distance(ft) Utility(ft) Crossings (Distance+Crossings) Water 500 33,000 6 58+ 18=74 Oil&Gas 500 20,000 3 30 +9=39 Telephone/Fiber 1000 5000 2 3+6=9 Electric 200 500 1 2+3=5 T2 UES, Inc.shall use minimally intrusive excavation techniques,which ensure the safety of the excavation and the integrity of the utility line to be documented. Other lines which may be encountered during the excavation will be noted.To help minimize the number of test holes required, T2 UES, Inc.will lay out the holes and re-designate the associated utility before excavation with input from the County. Test Hole Data Reports will be signed and sealed by a professional engineer and shall include project-specific coordinates,depth of the utility from the existing ground,material,and size of the utility found. QLA Investigation Assumptions • It is assumed that each hole will be excavated to find one utility per hole.If additional utilities are discovered within a hole,data for each will be collected,and a separate test hole report will be provided at no additional cost.The standard test hole dimension is a maximum of 10 feet deep and 18 inches wide. • The Client will have test hole locations determined and right-of-entry secured before T2 UES, Inc.'s services commence. If the parameters of the QLA investigation change after T2 UES,Inc.has initiated QLA services,T2 UES,Inc.will discuss the implications for workflow,traffic control,and other activities with the Client and determine if a change order or additional funds are needed to account for the changes. Learn more at T2ue.com I Page 5 T2 utility engineers Scope of Work a kiwa company WCR34 and WCR17 QLB Investigation_Rev4 • If concrete or asphalt coring is required,it will be completed under the reimbursable section for$200 per hole. • If the dimensions of a utility necessitate a test hole diameter exceeding 18 inches,trenching will be billed at a rate of$450 per foot.Trenching assumes a maximum depth of 10 feet. • The standard price for test holes indudes excavation to a depth of ten feet.An additional$95/foot will be billed as a reimbursable expense for every foot of depth over ten feet.If a test hole is on a QLC or QLD utility line,T2 UES, Inc.will excavate to a maximum depth of ten feet unless directed otherwise by the Client. • T2 UES, Inc. will do everything within our control to access the test hole locations; however, some areas may be inaccessible due to unsuitable terrain,limited access,weather conditions,truck limitations,safety concerns,etc.,and may not be able to be excavated.If any of these instances occur,they will be discussed with the Client and noted accordingly. • T2 UES, Inc.will provide traffic protection per local municipality specifications and permit requirements.This item will be subcontracted to a local traffic control company. The fee provided for this service is estimated based on quoted daily rates from the provider and a 10% coordination fee. • Removal of One-Call marks and designation paint, concrete panel replacement or restoration, landscape restoration,and shoring are not included. • The QLA test hole crew rates include One Call Management,Project Management,One Vac Crew with Personnel and Equipment, Survey, Concrete/Asphalt Coring,Updating the QLB/C/D SUE plans with QLA information,and QLA Test Hole Reports stamped by CO PE. • The provided rate for the per day for a QLA test hole crew assumes a minimum working time of eight hours per day. If T2 UES, Inc.is not able to work at least eight hours in a single day,we will invoice at the hourly crew rate. • Test hole restoration will conform to Weld County ROW Permit requirements.Per Weld County Permit requirements:Test holes in the natural ground will be backfilled using squeegee(crushed pea gravel),with a tamper used to ensure backfill is fully compacted.Test holes done in the asphalt will first be cored with the intact core removed.After completion of the test hole,hole will be backfilled using flowfill(if required) or squeegee(crushed pea gravel)if allowed by Weld County Permit. If backfilled with squeegee,a tamper will be used to ensure backfill is fully compacted.The core will be restored using Utilibond,which seals the core in place and prevents water from seeping into the subgrade. • It is assumed that flowable fill will be required for test holes performed in pavement.The cost estimate assumes there will be 36 test holes in pavement. SUE Investigation Deliverables Deliverables produced from this Subsurface Utility Engineering(SUE)investigation will be: • A utility drawing showing the location of the utilities within the investigation area at the achieved ASCE 38-22 Quality Level.Utility line work will be depicted according to Weld County's SUE Manual and SUE template.This drawing will be a digital 11"x 17"PDF plan set signed and sealed by a licensed PE.The drawing will include invert elevations referencing the Client's specified project datum and a utility contact list with utility providers,contact names,email addresses,and phone numbers,as well as other relevant information acquired during the utility records research. SUE drawings will include boundaries of the existing easements. Boundaries of existing easements will be provided by the Client to T2 UES,Inc. • An electronic file containing utility line work in AutoCAD Civil3D format using Weld County standards. The data collected in the QLA investigation will then be incorporated into the existing utility drawing. • Test hole Summary Reports presented in electronic format signed and sealed by a licensed PE.Test Hole Data Reports shall include project- specific coordinates, depth of the utility from the existing ground, material, and size of the utility found. The data collected in the QLA investigation will then be incorporated into the existing utility drawing. • T2 UES,Inc.will submit SUE deliverables at Concept,60%,95%,and final stamped plans at Advertisement.
