Box 758 Fax(970)353-8639 www.terracon.com Greeley, Colorado 80632-0758 Attn: Mr. Toby Taylor Re: Proposal/Agreement for Geotechnical Engineering Services Elevator Shaft Addition 915 10th Street-Greeley, Colorado Terracon Proposal No. P2108031g 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. A-PROJECT INFORMATION Terracon understands that an elevator shaft will be constructed at the site adjacent to the existing building on-site. We also understand that the elevator shaft will bear at approximately 8 to 10 feet below existing grade and will be designed to be supported by a helical pier foundation system. Structural loads for the proposed structure were not provided; however, Terracon assumes wall and column loads will not exceed 3 kips per lineal foot and 45 kips, respectively. Terracon also understands that the location of the shaft will require light weight drilling equipment due to the presence of underground personnel tunnels and parking garages. Accordingly, we will be using a portable hydraulic drilling rig with a total weight of approximately 300 pounds to advance the boring. B-PROPOSED SCOPE OF SERVICES The purpose of the geotechnical engineering services will be to evaluate the subsurface soil and groundwater conditions at the site. As requested, we propose to explore the subsurface conditions on the site with one test boring. The boring will be located in the anticipated footprint of the proposed elevator shaft and will be advanced to an approximate minimum depth of 30 feet. The boring will be advanced to the minimum depth outlined unless refusal to drilling is encountered prior to full boring advancement. The depth and location of test boring may be further adjusted depending upon actual subsurface conditions encountered. During the drilling operations, a Terracon representative will log the boring, 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. Delivering Success for Clients and Employees Since 1965 More than 95 Offices Nationwide Proposal/Agreement for Geotechnical Engineering Services Terracon Weld County Elevator Shaft Terracon Proposal No. P2108031g 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 site. 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; • Design criteria related to the elevator shaft construction, including maximum net allowable bearing pressures, lateral earth pressures, and predicted performance; • Unsatisfactory soil conditions and a discussion of remedial measures; and, • 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 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. It is anticipated that the field work for this project could commence on July 14, 2008, weather permitting, and that about one day would be required for completion of the drilling. An additional ten to 2 Proposal/Agreement for Geotechnical Engineering Services Terracon Weld County Elevator Shaft Terracon Proposal No. P2108031g 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. C -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— 1 day @ $400/day $400 Drill Rig—Drill—6 hrs @ $172.50/hr $1,035 Field Engineer—Site Layout/Utility Locates— 1 his @ $88/hr $88 Field Engineer—Drill—6 his @$73.50/hr $441 Estimated Subtotal—Field Exploration Services $1,964 Laboratory Testing Services Soils Classification Testing (Includes Atterberg Limits, -#200 wash, Sieve Analysis)— Estimate 3 @$118/each $354 Swell Consolidation Test— Estimate 2 @ $85/each $170 Moisture Test—Estimate 7@ $5/each $35 Density Test—Estimate 2 @ $5/each $10 Estimated Subtotal—Laboratory Services $569 Report Preparation and Engineering Recommendations Staff Engineer-Boring Logs/Laboratory Data Entry/AutoCAD—3 his @ $73.50/hr $220.50 Geotechnical Engineer—Final Recommendations/Report Preparation—4 hrs @$88/hr $352 Principal Engineer—Report Review— 1 hr @$103/hr $103 Estimated Subtotal—Report Preparation and Engineering Recommendations $675.50 Estimated Total $3,208.50 AUTHORIZATION 3 Proposal/Agreement for Geotechnical Engineering Services Terracon Weld County Elevator Shaft Terracon Proposal No.P2108031g We appreciate the opportunity of submitting this proposal, and are available to discuss the details with you.
