No ATTACHMENT(S): INFORMATION CONTACT: Pam Jones, ext. 2650 Proposal/contract Wilbert McAdoo, ext 2626 Telephone Numbers- Hillsborough 732-8181 Chapel Hill 967-9251 Mebane 227-2031 Durham 688-7331 PURPOSE: To consider approving a contract with RTD Associates, P.A. to conduct an analysis of each and every roof on County buildings. BACKGROUND: Orange County offices are covered by over 235,000 square feet of roofs. Each roof varies in the quality, life expectancy and maintenance required. Heretofore, the County has had no replacement/maintenance schedule whereby budgetary estimates and projections could be made. In an effort to protect the investment made by Orange County citizens in County buildings, it is suggested that such a schedule be created. In order to accomplish this in a reliable manner, a baseline of roof status should be established. The work proposed by RTD Associates will provide this critical information. The proposed cost for the assessment is $19,240. In addition to the assessment, it is suggested that RTD prepare a multi-year maintenance/management plan to guide the County in future budgetary initiatives. The cost for preparation of this plan is $3,800. RTD Associates is a Charlotte, NC firm which has done other work for the County over the past several years. Historically, their work and budgetary estimates have been very reliable. Funds are included in the existing Capital Improvement Plan to cover the cost of this work. RECOMMENDATION: The Manager recommends that the Board approve the contract with RTD Associates, P.A. for a sum not to exceed $23,040; and authorize the Chair to sign on behalf of the Board. 2 y TD Associates, P.A.

We propose to provide our specialized Roof Engineering expertise as listed below for the above- referenced project. ROOF DIAGNOSTIC SERVICES 1. Visual Analvsia A thorough visual inspection shall be performed of the roof surface area to locate, identify, and photographically document the surface deficiencies, including those relating to current or anticipated water entry. 2. Sub-Surface Moisture Evaluation A complete and thorough sub-surface moisture evaluation shall be performed using infra-red thermographic and nuclear hydrogen detection equipment. All areas of sub-surface moisture or wet insulation shall be located and confirmed by galvanic moisture probing or core sample. The anomaly(sub-surface moisture)will be delineated onto the roof surface and plotted by size on an accompanying roof plan. Written and photographic documentation will also be provided to support all information gathered and evaluated.

Core SawRle Analysis Core samples of the roof assembly shall be taken and evaluated to determine: a. The type,quantities,and condition of the various materials which are contained within the roof assembly. b. The condition of roof substrate (deck) shall be determined and documented at the location of the core sample taken. Written and photographic documentation shall be provided to illustrate the above factors. 4. Roof Drainage Profile AnaWis a. An examination and calculation of the existing drainage integrity and capacity shall be made and compared with the actual existing requirements. b. Calculated documentation of any dead load contribution by ponding water shall be performed. A roof plan illustrating approximate size and location of drainage deficiencies shall be included. 5. EneM Loss Evaluation A formatted comparison of the as-designed "R" Value with the existing "R" Value shall be compiled to reflect,in dollars,any energy loss due to sub-surface moisture or wet insulation. 6. Serviceability Forecast A mathematical calculation will be performed to illustrate the longevity, as affected by the compounding nature of existing roof problems or deficiencies. A lineal chart will be provided to graphically illustrate the anticipated effective roof service life remaining. 7. Conclusions/Recommendations A statement pertaining to the roofs current state of condition and relative problems shall be made,followed by a statement discussing the various alternatives of viable corrective actions. 8. Budget Costs A preliminary estimate of contractor's labor and material costs for the recommended corrective actions shall be calculated.
