(Terracon) appreciates the opportunity to submit this proposal to provide material testing and inspection services relative to the above-referenced site. Our proposal includes an outline of the project information provided to us, the proposed scope of services and our estimated fees based upon guidelines set forth by Weld County Public Works. These fees include quality control testing for asphalt paving. PROPOSED CONSTRUCTION We understand the project will involve approximately 23,647 cubic yards of aggregate base course, 21,832 tons of asphalt, and 15,600 cubic yards of embankment fill. There are also 360 linear feet of curb and gutter, splash aprons and numerous box culverts. It is our understanding that the project will commence October of 2007 with a projected finish date of July of 2008. Based upon our understanding of the project, the following quality assurance material testing services may be required for the proposed construction: • Field density-compaction testing and laboratory evaluation of soils for embankment backfill, pavement sub-grade, and structure backfill; • Field and laboratory testing of concrete; • Field and laboratory testing of asphalt-concrete. Delivering Success for Clients and Employees Since 1965 More Than 90 Offices Nationwide Weld County Road 13: WCR 8 to HWY 52 Material Testing and Inspection Services Terracon Proposal No. C2207082 Field Density—Compaction Testing: An engineering technician will be provided on a part-time or as-requested basis to perform materials testing services for earthwork. We understand testing will consist of moisture-density relationships, one point checks, gradations, Atterberg Limits and compaction testing with a nuclear density gauge. The testing frequency will be in accordance with the current Colorado Department of Transportation (CDOT) Field Materials Manual Quality Control Schedule. Concrete: An engineering technician will be provided on a part-time or as requested basis to sample fresh concrete used during construction. The concrete will be tested for slump, air content, unit weight, and temperature at the time of placement during construction. Compressive strength testing will be performed to determine compliance with project specifications. Test results will be provided in the field for your review and compressive strength test results will be conveyed as available. The testing frequency will be daily and as scheduled per the contractor's request. The areas that shall be addressed are curb and gutter, splash aprons, and box culverts. Asphalt: Field density-compaction testing by nuclear methods and coring will be provided by an engineering technician, on an as-scheduled basis, during the placement of asphalt concrete at the project. Test samples will be taken to supplement the quality control testing being performed by the asphalt supplier. A Terracon representative will also obtain samples for laboratory tests as required. Daily reports of test results will be available on-site for your review. Engineering, Supervision and Clerical: Engineering, supervision and clerical services will be provided as required to manage the project and prepare formal reports. Compensation: We understand the project will be completed in approximately 139 working days. We anticipate one technician will be required on an on-call basis, and that the average technician work day will consist of two to four hours with a five-day work week being typical. These hours may increase during heightened activity depending on the amount of inspection services that are requested.
