ADDENDUM #1

This Addendum forms a part of Contract and clarifies, corrects or modifies original Bid Documents. Acknowledge receipt of this addendum in space provided on bid form.

Failure to do so may subject bidder to disqualification.

This addendum contains 18 sheets including this sheet.

A. All roofing systems shall be furnished under a single manufacturer’s warrantable system. Mixing systems from different manufacturers is not permitted.

B. See attached roof scan report. Contractor shall use this report to identify areas of wet insulation for removal and replacement and are to confirm conditions prior to bidding.

C. The approximate roof area is noted incorrectly in the bid documents. The corrected approximate areas are as follows:

• Total 2-ply roof area: 11,100 SF

• Recover roof system: 8,900 SF

• New 2-ply roof system: 2,200 SF

D. Contractor shall re-use the stainless steel expansion joint curb at the wall-to-roof conditions.

Infrared Roof Inspection

April 23, 2025

Andrew Kesler, Landen Gay and Tyler Montgomery of Kesler Simpson Architects were on site at the

Walton National Guard Armory, on April 23th 2025 at 7:00 to perform an infrared thermal scan of the building’s roof system.

Arrival temperature was 68 degrees. Departure temperature was 56 degrees.

Total roof area: approximately 11,100 square feet

Total wet area: approximately 1,500 square feet

Total dry area: approximately 9,600 square feet

Percent wet: approximately 13.51%

A visual scan was performed of the roof once on site. Standard practice for location of wet insulation in roofing systems with the use of an infrared imaging camera was our protocol. When anomalies were identified on the roof they were outlined with a semi-permanent paint. Thermographs and photographs were taken and documented in this report.

The infrared camera used in this inspection was a Flir model E40BX. IR lens, F= 18 mm. IR resolution

19,200 (160x120), Thermal sensitivity <.45mk, Field of view 25degreesHx 19degreesV, Temperature range -4 to 248 degrees F, accuracy +- 2% rdg.

The infrared roof survey locates moisture in a roof by seeking areas of increased surface temperature.

Roof areas that contain moisture have higher thermal conductivity and capacities than dry areas. During the heating season, heat from the building interior is lost at a greater rate through wet roof areas and their surface temperatures are elevated. Alternatively, during the cooling season, solar heat is absorbed into the wet area, and then retained for hours after the sun sets.

Detecting entrapped moisture with insulated buildings is achieved through proper evaluation and application of thermographic imaging. To understand the methodology for infrared roof evaluations, it is important to first comprehend how thermal differences are analyzed when applied to areas of wet and dry insulation.

During the day, sun radiates energy onto the entire roof surface (solar loading), Later in the day, the wet insulation has the capability to retain more energy (heat capacity). Areas of the roof that are higher mass

(wet) retain heat longer than the lower mass (dry) areas therefore radiate heat for a longer period of time, because it takes longer to cool. The result of the infrared survey is a thermograph indicating areas of suspected moisture as different colors as dry. Additionally, surface heating pattern anomalies are colorized to delineate and make flaws within the roof more discernable.

Because higher surface temperatures, and consequently hotter colors, may be produced by several phenomena not related to moisture intrusion, tests are made to verify the findings of the infrared inspection using destructive testing (core cuts - moisture meter) and other non-destructive tests

(capacitance and nuclear). Wet areas found by infrared testing are illustrated with thermographs of infrared images.

Our report is based on information obtained at the site at the given date and time. Over time, conditions change and the information contained in this report may no longer be accurate. Should additional information become available at a later date, we reserve the right to determine the impact, if any, the new information may have on our discovery and recommendations to revise our opinions and conclusions if necessary and warranted. Any areas shown in this report are approximations of anomalies. Exact dimensions of anomalies are not feasible to obtain.
