RFP 4 87 05 04 Eagle County Engineering Department P.O. Box 850 Eagle, CO 81631 Attn: Susanna Struble Dear Susanna: As requested, Chen & Associates is pleased to provide a cost estimate for compaction and asphalt testing for the proposed El Jebel Hill Road Improvements. The improvements are to consist of new roadway widening and realignment, and pavement construction on two miles of the road. We previously performed a subsoil study for site grading and pavement design of the project, submitting our findings to you in a report dated November 26, 1987, Job No. 4 407 86. From our discussion with you regarding the project, we under- stand the assumed construction time for the earthwork and base course placement will be about 1 1/2 months. The testing is to be on a part-time daily basis. We submit the following estimate for our services: Compaction Testing -Soils (Assume 5 weeks) Technician: 25 trips (3 hours per trip) _ $2650 Proctor Tests: 4 at $147 each = 588 Subtotal 3238 Compaction Testing -Base Course (Assume 1 week) Technician: 5 trips (3 hours per trip) = 530 Proctor Test: 1 each at $115 = 115 Subtotal $ 645 Eagle County May 22, 1987 Page 2 u Engineering Department Asphalt Testing (Assume 1 week) Technician: 5 trips, 8 hours/day = 1310 Coring: 5 days, 2 hours/day at $60/hr. = 600 Marshall Test, 1 per day: 5 at $125/each 625 Extraction/Gradation, 1 per day: 5 at $90/ea. _ 5 Subtotal $2985 Engineering Review of Daily Reports and Report Typing Engineer: 2 hr•s/wk, x 7 weeks at $45/hr. = 630 Word Processing: 2 hrs/wk, x 7 weeks at $25/hr. _ 5 Subtotal $ 980 Estimate Total $7848 Since the actual time and required testing for the job will be dependent primarily on the construction schedule and materials encountered, we propose our fees be based on unit costs in accor- dance with the attached Fee Schedule. We will keep our costs to a minimum, consistent with providing adequate testing services. To reduce costs, we will split travel time and mileage with other jobs in the area when possible. We expect to be in the area most of the construction season. If this proposal meets with your approval, please sign one copy and return it to this office. If you have any questions, don't hesitate to call. We look forward to working with you on the project. DAY/ec Attachment Rev. By: S.L.P.
