Z--Dworshak National Fish Hatchery, Fish Health Lab Roof Replacement

Construction Project: This project includes complete removal and replacement of the existing roof system installed on the original portion of the Fish Health Laboratory located at Dworshak National Fish Hatchery in Orofino, Idaho. Demolition work consists of removing the old 5-ply built-up roofing (BUR) system, all lightweight concrete substrate used to create slope under the existing roofing membrane system, and existing rigid roof insulation down to the existing corrugated steel roof decking. An existing roof-mounted guardrail system used around existing rooftop HVAC units will also require complete demolition. Felts and mastics used on the old roof contain measurable amounts of asbestos fibers. The new roof system will start with flat-stock polyiso insulation attached to the existing steel roof deck with screws and metal plate washers followed by glue-installation of faced polyisocyanurate (polyiso) insulation in flat and tapered profiles. The tapered polyiso insulation will be topped by an adhered layer gypsum roof sheathing. The new waterproofing for the roof assembly will consist of a fully-adhered 60 mil unreinforced EPDM single-ply roofing membrane. The tapered polyiso roof insulation will be used to create a -inch per foot slope to new continuous sheet metal gutters located on two sides of the roof. The total area of reroofing at the Lab Building is approximately 2,844 square feet. There are currently four HVAC units located on the existing roof which will require temporary removal in order to facilitate demolishing the old roof and installing the new one. Electrical power is fed to the existing HVAC units via wire in electrical conduit mounted directly on the existing surface of the roof. This contract requires replacement and relocation of the old wiring and conduit in order to facilitate installation of the new roof system, bringing the old wiring and conduit up to current NEC standards, and ensuring that conduit is located where it will not present a tripping hazard to maintenance personnel. Mechanical and electrical work are optional line items, depending upon availability of funds for that portion of the work. The period of performance is expected to be 120 calendar days after the date the Contractor receives notice to proceed with construction. The construction magnitude is estimated to be between $100,000 and $250,000. Performance and payment bonds in the amount of 100% of the contract price are required. A bid bond is required in the amount of 20% of the total bid price. The North American Industry Classification System (NAICS) code for this work is 238160, Roofing Contractors.
