This document is a report on the condition of the roof for the Central Administration section of a building located at 4000 Cooper St. The roof is a mechanically attached EPDM system that is approximately 15 years old. Several defects were noted throughout the roof, including delaminated flashings at all roof penetrations, damaged roof membrane, and delaminating field seams. The report provides three repair specifications: 1) Remove the existing roof and replace with a like system, 2) Apply a restorative coating over the existing roof, and 3) Remove the existing roof and replace with a fully adhered EPDM system. The total cost to perform the recommended repairs is $110,243. The report states that the roof has the potential to last up to 5 more years with the recommended repairs and routine maintenance. The report also includes a detailed breakdown of the specific deficiencies, their locations, repair costs, and photo IDs.

The report indicates that the strategy for this roof is to perform repairs to attain the most serviceable life. It provides the square footage, replacement cost, and restoration cost for the roof. No information is provided regarding any set asides, incumbents, funding requirements or sources, or contract term and renewal options.

The roof and its components were inspected on section 10 of the building known as Central Administration. The mechanically attached EPDM stairwell roofs appear to be in fair condition at approximately 15 years of age. Several defects were noted through out the roof including delaminated flashings at all roof penetrations, damaged roof membrane and delaminating field seams. The roof has the potential to last up to 5 more years with the recommended repairs performed and with routine maintenance and inspections.

The costs shown for the roof replacement, restoration and alternate specifications are for the purpose of budgeting only and may be subject to change.

The replacement specification is to remove the existing roof and replace with like system.

The restoration specification is to apply Andek restorative coating over the existing roof surface.

The alternate specification is to remove the existing roofing and replace with a fully adhered EPDM roof system at a cost of: $388,800
