BACKGROUND: The contract with Trigon for$2,550 is presented for approval pursuant to the policy adopted by the Board of Commissioners on October 3, 1988, in which the Board expressed a desire to approve all contracts with licensed professional firms, such as for architectural and engineering services, regardless of monetary value. The scope of work for this contract is as follows: 1. Explore the general subsurface conditions in the area of the proposed additions; 2. Evaluate those conditions with regard to the design and construction of foundations and floor slabs; 3. Perform seven (7)test borings for the Jail addition and three (3) borings for the courthouse addition; 4. Prepare a report which addresses: a. The suitability of the subsurface conditions at the site for construction of foundations and slabs; b. Considerations regarding subgrade preparation,presence of groundwater, presence of rock;and c. Fill compaction criteria. Three proposals,based on identical scope of work, were received. Trigon submitted the lowest cost. The project architect has indicated that while all three proposers are well qualified to perform the service,they recommend the lowest cost proposal as well. RECOMMENDATION: The Manager recommends that the Board approve a contract with Trigon Engineering Consultants,Inc.in the amount of$2,550 for geotechnical services associated with the Jail Addition and the Courthouse Addition Projects;and authorize the Chair to sign on behalf of the Board.

Tierney Engineering 6015 Chapel Hill Road Raleigh, North Carolina 27607 Attention: Mr. Glenn Eason, P.E. Reference: Proposal for Subsurface Exploration Orange County Jail and Courthouse Additions Hillsborough, North Carolina Gentlemen: Trigon Engineering Consultants, Inc. (Trigon) appreciates the opportunity to submit this proposal to conduct a subsurface exploration and geotechnical evaluation for the proposed additions to both the existing Orange County Jail and Courthouse in Hillsborough, North Carolina. This proposal has been prepared based on the information provided by Mr. Glenn Eason of G.J. Tierney Engineering. Outlined in this proposal is a brief description of the project along with our proposed scope of services and an estimated fee. PROJECT INFORMATION The project will consist of the construction of an addition to both the existing Orange County Jail and Courthouse buildings. The jail structure is a two- and three-story building consisting of reinforced concrete with bearing walls and beam-column construction. We understand that maximum column and wall loads are on the order of approximately 400 kips and 6 kips/foot, respectively. Finish ground floor elevation of the existing structure is at 524.17 feet (site datum). The courthouse addition will be a lightweight, one-story and bearing wall structure. For this type of construction, we anticipate that wall loads will not exceed 3 kip/foot. 5 Mr. Glenn Eason July 27, 1994 Page Two PURPOSE AND SCOPE The purpose of the subsurface exploration will be to e_xplore the general subsurface conditions in the area of the proposed additions and to evaluate those conditions with regard to the design and construction of foundations and floor slabs. For purposes of this proposal, seven (7) soil P boring aze_,p osed; four borings for the jail addition and three borings for the courthouse addition. Boring depths are proposed at 30 and 20 feet, respectively, or to refusal. In each boring, Standard Penetration Tests will be performed in general accordance with ASTM D 1586-84 at suitable spacings to characterize the general subsurface conditions of the site. The borings will be staked in the field by Trigon using the existing onsite structures as references. Access to the borings appears to be clear. Since the borings may be advanced to refusal, some hard drilling will likely be required. We have budgeted for potential hard drilling. The results of the field testing will be summarized in a written report prepared under the direction of a registered professional engineer. The report will address the suitability of the subsurface conditions at the site for construction of foundations and slabs. Construction considerations regarding subgrade preparation, presence of groundwater, presence of rock, and fill compaction criteria will also be addressed. ESTIMATED FEE AND SCHEDULE Based on the scope of services outlined above, our estimated fee to perform an exploration for the jail and courthouse additions is $2,550. If a geotechnical exploration is to be performed for the jail addition only, an estimated fee of $1,770 is proposed. Our services will be provided on a time and materials basis at the appropriate unit fees using the estimated fee as a maximum not to exceed without your approval. If subsurface conditions are encountered that suggest modification to the proposed scope as previously noted, you will be contacted immediately for both your review and authorization. We can usually begin the field portion of the subsurface exploration within a few days after receiving formal authorization to proceed. AUTHORIZATION This proposal is an agreement for our services. Verbal authorization can be provided for scheduling of services; however, for insurance purposes, we will require written authorization prior to the mobilization of our personnel and equipment to the site. If our proposal is accepted, please take a few moments to complete and return the attached Proposal Acceptance Sheet. Please note the general terms and conditions on the back of the sheet, and that our terms for Mr. Glenn Eason July 27, 1994 Page Three payment are net due 15 days from date of invoice.
