About this file
This is a Roof Diagnostic Survey document prepared by Tremco Incorporated for Forsyth County, Georgia, specifically for the Central Recreation facility located at 2300 Keith Bridge Road in Cumming, Georgia. The survey employs a moisture density assessment methodology using a Roof Moisture Density Gauge to identify wet and dry areas within the existing roof system. The diagnostic process involves marking a 10'x10' or 5'x5' grid pattern on the roof surface, taking readings at each grid intersection to detect hydrogen presence (indicating moisture), and performing core cuts to establish baselines for dry roof materials. Wet roof areas are marked with visible paint for identification and documentation purposes. The survey results are presented in a roof plan drawing with numbered grid readings and includes core samples (numbered 1A through 5A) taken to validate findings.
The document serves as a supporting exhibit for Forsyth County's sealed bid solicitation for roof replacement and restoration services at the Central Park Recreation Center. The moisture survey provides contractors with detailed information regarding the condition of the existing metal and gravel roof systems, enabling more accurate bid preparation and scope definition. The diagnostic findings, combined with photographs and thermographic data included in the survey, establish a baseline condition assessment that informs the specifications for the replacement project. No pricing, funding sources, set-asides, or contract terms are specified within this diagnostic survey document, as it functions solely as technical reference material for prospective bidders evaluating the scope and condition of the roof systems requiring replacement.

How A Moisture Density Survey Works:
During the daytime, a 10'x10' or 5'x5' grid pattern is marked on the roof surface. Readings are taken and recorded at each grid intersection.
Fast neutrons are emitted from the source in the Roof Moisture Density Gauge into the roof system.
The presence of hydrogen in the roof system slows the neutrons. These slowed neutrons as well as the fast neutrons are detected by the Roof Moisture Density Gauge "detectors". A reading is displayed in the digital readout and gets recorded.
Core cuts are taken to determine a baseline for dry roof materials. Then wet roof areas are marked on the roof surface with visible paint markings.
