Question- There are no taper slope indication (roof deck or insulation) on the roof drawings-

Answer- Ponding (standing water) will not be allowed on any completed roof. Install crickets and tampered insulation to insure no standing water is present on completed roofs. The contractor shall field verify the existing slope of each roof and determine the need for tapered insulation during the pre-bid walk through. It is intent of the design for the contractor to provide a roof cricket adjacent to all existing drains to insure no ponding is present after the roof is completed.

At the access doors for Roof B and Roof E there has been ponding adjacent to the access doors to these roofs. For these two areas we are requesting large crickets to be installed for 20’ out from the existing door x 25’ - to shed water away from these areas.

Question- There are no indication of electrical installation needed for lightning protection etc. Please advise.

Answer- Remove and re-install the perimeter lightning protection system cables on each roof. The contractor will need to mark the existing cables to reinstall them correctly. If the contractor misplaces or damages the existing lightning protection cable, he will need to replace the cable with cable by Thompson Lightning Protection Company (Type A28 28 x 14 gauge). Provide new cable attachments and lightning rod supports- new A730 Cable Holders for Aluminum cable installed 5’ on center and A66 Bases for Air Terminals (Thompson Lightning Protection) and 2’ air terminals (Thompson A571BT). The contractor shall confirm part numbers and quantities for a complete lightning protection system. Save all cables connectors and other hardware to be reinstalled. Replace missing or damaged parts in kind.

Question- Please provide spec/information about wall panel system to be installed:

- type of wall panels

- thickness or gage

- type of metal

- type of sub-grid and size

- gage of sub-grid

Answer- Provide metal siding to cover the existing brick along the inside of the parapet walls where called for in the contract documents. Install this siding on 1” galvanized steel hat channels that are expansion bolted to the existing brick. The new coping along the top of the parapet walls shall be fabricated to accommodate the siding installation. The corrugated siding panel shall be galvanized steel, bronze in color, and 20 gauge. Provide stainless steel screws with matching bronze covers. S &J Sheet Metal Supply (L.I. Tinsmith Supply) meets this specification.
