Box 758 Fax 970.353.8639 Greeley, Colorado 80632-0758 www.terracon.com Attn: Mr. Mike Bedell Re: Proposal/Agreement for Geotechnical Engineering Services Weld County Road 2 Between Weld County Road 45 and 1-76 Weld County, Colorado Terracon Proposal No. P2107057g Terracon is pleased to submit this proposal for providing geotechnical exploration and engineering services for the subject project. This proposal includes an outline of the project information provided to us, our scope of services, fee, and schedule. PROJECT INFORMATION Terracon understands the project will consist of paving three miles of Weld County Road 2. The proposed section to be paved will extend from the end of the existing pavement (approximately Y mile west of Weld County Road 45) to a point approximately 1/2 mile west of Weld County Road 39. We understand that Weld County will be performing the pavement design for the project, and that this design will be based on the soils information generated from our exploration and testing at the site. The scope of services and estimated fees for the project have been developed through coordination with the client. Proposed grade changes to the road were not developed at the time of this proposal. Terracon assumes some minor grade changes to accommodate line of site issues for the project will be necessary. For the purposes of this proposal, Terracon assumes site grading cuts and fills will be less than 3 feet. SCOPE OF SERVICES The purpose of the geotechnical engineering services will be to evaluate the subsurface soil and groundwater conditions at the site and to provide soils testing for a pavement design to be performed by Weld County. We propose to explore the subsurface conditions on the site with a total of 32 test borings (based on a minimum of one boring per 500 linear feet). The borings will be advanced to approximate minimum depths of 5 to 10 feet. The minimum depth of 5 feet assumes cuts will be less than 2 feet. If cuts greater than 2 feet are included with the project, the 10 feet borings will be required. The borings will be advanced to the minimum depths outlined unless refusal to drilling is encountered prior to full boring advancement. The depth and location of test borings may be further adjusted depending upon actual subsurface conditions encountered. Delivering Success for Clients and Employees Since 1965 More Than 90 Offices Nationwide Proposal/Agreement for Geotechnical Engineering Services Terracon Weld County Road 2 Terracon Proposal No. P2107057g During the drilling operations, a Terracon representative will log the borings, record the results of penetration tests, and obtain representative samples for further laboratory evaluation. Groundwater measurements will be made in each boring during exploration and a minimum of 24-hours after drilling. Drilling and sampling will be conducted in general accordance with applicable local standards. At the completion of drilling operations, all samples will be returned to our laboratory where they will be examined by the project geotechnical engineer. At that time, the field descriptions will be confirmed or modified and an applicable laboratory testing program will be formulated and final boring logs prepared. Relatively undisturbed samples may be tested for moisture content, dry density, and consolidation and expansion characteristics. Disturbed samples may be tested for liquid limit, plastic limit, moisture content, and grain size distribution. Laboratory testing will be conducted in accordance with applicable locally recognized standards. The information obtained from the field exploration and laboratory testing program will be used to evaluate the soil and subsurface conditions at the project site. Based on these results and on our recommendations, Weld County will be able to perform a pavement section design. Based upon our analyses, a geotechnical engineering report will be prepared. The following information will be provided in the report: • A brief review of our field and laboratory procedures, and the results of all testing conducted; • A discussion of the general subsurface conditions including soil and groundwater conditions; • Location and characteristics of groundwater; • Unsatisfactory soil conditions and a discussion of remedial measures; • Recommended construction procedures and quality control measures related to earthwork. Terracon will notify the Utility Notification Center of Colorado (UNCC) for location of public utilities a minimum of 3 business days prior to our anticipated drill date. Terracon is not responsible for potential 2 Proposal/Agreement for Geotechnical Engineering Services Terracon Weld County Road 2 Terracon Proposal No. P2107057g damages or impacts to our schedule if adequate utility locates are not performed, or utility locates are not completed by UNCC prior to our expected drill date. Terracon assumes that site access will be open, and that the site is accessible with a 2 wheel drive Ford F-750 truck with a CME-55 or CME-75 drill rig mounted on the back. If, once we arrive on site, it is apparent the site will not support the above referenced drill rig, additional charges, including equipment costs for towing the drill rig or remobilization to the site, will be applicable. Further, if the area to be drilled will require traveling over landscape areas, Terracon is not responsible for damage to landscaping if suitable alternate routes to access the site are not available. SCHEDULE It is anticipated that the field work for this project could commence within five to ten business days of receipt of written notice to proceed, weather permitting, and that about one to two days would be required for completion of the drilling. An additional ten to 15 working days would be required for the completion of laboratory testing, engineering analyses and development of the final report and recommendations. Verbal communications, including preliminary findings and recommendations, can generally be issued approximately 3 to 5 working days after completion of the field work and prior to issuing the final report. COMPENSATION The cost for our services, including all field work, laboratory testing, engineering analyses and report preparation (five copies will be provided), will be on a unit rate basis. The following is a line item estimate based on our discussions with Weld County: Field Exploration Services Drill Rig—Mobilization/Demobilization—2 days @ $400/day $800 Drill Rig—Drill — 12 hrs @ $136/hr $1,632 Field Engineer—Travel—4.5 hrs @ $70/hr $315 Field Engineer— Site Layout/Utility Locates/County Permit—4 hrs @ $70/hr $280 Field Engineer— Drill— 12 hrs @ $70/hr $840 Traffic Control—2 days @ $950/day $1,700 Estimated Subtotal— Field Exploration Services $5,567 3 Proposal/Agreement for Geotechnical Engineering Services Terracon Weld County Road 2 Terracon Proposal No. P2107057g Laboratory Testing Services Soils Classification Testing (Includes Atterberg Limits, -#200 wash, Sieve Analysis) — Estimate 6 @ $115/each $690 Swell Consolidation Test— Estimate 6 @ $85/each $510 Moisture Test— Estimate 2/boring*32 borings @ $5/each $320 Density Test— Estimate 2/boring*32 borings @ $5/each $320 Hveem Stabilometer"R-Value" — Estimate 6 @ $300/each $1,800 Standard Proctor— Estimate 6 @ $115/each $690 Estimated Subtotal—Laboratory Services $4,330 Report Preparation and Engineering Recommendations Staff Engineer- Boring Logs/Laboratory Data Entry/AutoCAD— 10 hrs @ $70/hr $700 Geotechnical Engineer—Final Recommendations/Report Preparation —4 hrs @ $85/hr $340 Principal Engineer— Report Review— 1 hr @ $100/hr $100 Estimated Subtotal—Report Preparation and Engineering Recommendations $1,140 Estimated Total $11,037 AUTHORIZATION We appreciate the opportunity of submitting this proposal, and are available to discuss the details with you.
