McAdoo Re: Roof Analysis Director of Public Works Selected Roof Areas Highway 86 North Hillsborough,NC 27278 Dear Mr. McAdoo: As a Professional Engineering firm specializing in the specific areas of Roof Diagnostics, Engineering, Design, and Project Management, we respectfully request your consideration of the following, proposal.. ' We propose to provide our specialized Roof Engineering expertise as listed below for the above- referenced project. ROOF DIAGNOSTIC SERVICES 1. Visual Analysis 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.

McAdoo, Director of Public Works Orange County Page 2 PROJECT: Roof Analysis, Selected Roof Areas DATE: November 4, 1997 3. Core Sample 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 Analysis 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. En�Y 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 Costa A preliminary estimate of contractor's labor and material costs for the recommended corrective actions shall be calculated A roof service life chart will also be included to illustrate the pro-rated life cycle costs of maintenance costs versus replacement costs and potential extended service life through maintenance.
