About this file
This document is an architectural drawing detailing roof and hangar door construction specifications for Gateway National Recreation Area at Floyd Bennett Field. The drawing sheet (A5.0.2) contains nine detailed construction sections addressing parapet walls, hangar doors, roof assemblies, and drainage systems.
The specifications require installation of multi-layer roof systems incorporating hot-applied rubberized asphalt, polyester and fiberglass reinforcing sheets, polyurethane base and top coats, rigid insulation with tapered layers for slope creation, and roof coverboard over existing concrete decks. Hangar door work includes cleaning and painting existing upper tracks, removing and reinstalling aluminum panels with aluminum rivets, replacing rolling wheels with historic in-kind replacements, and installing neoprene and nylon brush weatherstripping. Copper components throughout include scuppers, counter flashing, coping, conductor heads, downspouts, and corrugated copper sheathing, all requiring matching of existing profiles and sizes. Roof drainage details specify drain bodies with perforated extensions, clamp rings, and deck clamps positioned at specified on-center spacing with overflow drains set 2 inches minimum above main drains. The contractor is required to verify all existing field dimensions, completely remove hangar doors from tracks for restoration, review salvaged door wheels for reusable parts, and ensure all doors are reinstalled to full operability. Wood blocking, plywood substrates, and exterior-grade tongue-and-groove wood decking require installation or replacement as specified in related structural drawings.
