Roof Area J -2a — Base Bid Roof Area: Roof Area J -2a is generally located at the northwestern portion of the central Mall area, west of JC Penny, and directly behind the AMC movie theater, adjacent the galleria as indicated on Project Roof Plan Drawings. Due to the nature and location of this Project, with the new work designed to tie-in to the .existing overlay roof system, adjacent the drainage wall, it has been determined with the specified Roofing Membrane System Manufacturer that running plies parallel to the prevailing slope will provide the best fall -season roofing installation results. This process would be carried through the membrane roofing interply (i.e., Paradiene 20) only --with the subsequent Paradiene 30 cap sheet being set in the traditional perpendicular to the slope configuration. This part of the re -roofing process will require extra care (i.e., brooming or rolling) to assure that the cap sheet is properly and thoroughly adhered/bonded to the underlying interply sheet as it traverses over each of the side lap seams of the material running in the opposite direction. D. Included in the Base Bid reroofing work is watertight flashing of the elevated concrete equipment pad with new 2 -ply SBS membrane flashing system, stripped -in all around and at vertical terminations with reinforced PMMA membrane watertight flashings. 1. Alternate Bid: Prepare, prime, and roof -in the elevated concrete equipment pad watertight with newly adhered, heat -fused SBS -modified bitumen roof membrane base ply, overlaid with fully -fleece reinforced, sanded -quartz finish, fully -adhered PMMA roof membrane system. E. Items are included in the Bid Form for pricing portions of work regarding: Repairs and/or Retrofit of the existing steel roof deck; Localized sacrificial interply membrane sheet installations; Remediation of localized low lying portions of the roof where potential ponding water could otherwise develop; and, Installation of additional steel deck fasteners. 1.4 RELATED DOCUMENTS AND BENCHMARKS A.
