PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK Background: The original building was built in 1927. In 2002 during the rehabilitation contract all roofing material was removed and replaced. Due to the age of the EPDM roofing and gutter lining material, numerous leaks have been located and repaired. Water damage has occurred in interior rooms. The goal of this project is to replace EPDM roofing material on the auditorium flat roof, auditorium vestibule, two upper flat roofs, gutter lining and to install an updated Ice Melt System on the auditorium flat roof surface.

1.1 Work Covered by the Contract Documents:

A. Project Location: Shawnee, Kansas

B. Work consists of: The general scope of this project is to demo and replace existing EDPM roofing and tapered insulation to match existing on the auditorium flat roof, auditorium vestibule, two upper flat roofs. The existing gutter liner will be used as the base material for a new gutter liner as described below and as shown. (Appendix A). It also includes removal and replacement of the existing Sno-Trace (or equal) system with an upgraded commercial snow melt system. There is approximately 3,560 SF of EPDM and tapered insulation for removal (demo) and replacement, including all penetrations including, splash boxes and penetrations on all surfaces. (See Appendix A for Drawings and B for Photos) The contractor will also add a 36” x 60” EPDM landing pad at the top and bottom of the fixed ladder leading from the vestibule roof to the auditorium roof. In addition to the roof replacement approximately 532 linear feet of gutter lining needs to be replaced. Insulation panel slopes will match existing to ensure water moves to downspouts and does not cause ponding. Any damage caused by the contractor to the clay roof tiles or lightning protection will be contractors’ responsibility to repair or replace. All replacement materials must match the existing. (in-kind) Water infiltration has led to some roof leaks and repairs have been made.

The existing gutter lining will not be removed to prevent damage to the clay tile. The new liner will have the least number of joints as possible. The new liner will be fully attached to the fascia with a new termination bar screwed to the fascia 1’ under the tile edge. The vertical 1” space above the termination bar will have a 24 Ga. Flashing, fully sealed and screwed to the fascia extending over the termination bar with a drip edge. The existing lining will be completely cleaned to allow the new liner to be fully adhered to it. The new liner will extend in one piece down the fascia, across the bottom, up the outside of the gutter and over the top to the exterior edge where the existing EPDM is terminated. Drawing in Appendix A and example photos in Appendix B.

Lighting Protection system will be protected including cables and rods. If work consist of removing this system contractor will re-install. Any damage will be the responsibility of the contractor to repair or replace. If the system is removed or disconnected for any reason, the system must be retested and certified after reinstallation by a third party with certification provided to the NPS at the contractor’s cost.
