About this file
This document is a comprehensive specification set for a roof replacement project at the Pine Ridge Correctional Facility (PRCF), a minimum-security transition and re-entry facility located in Baker City, Oregon. The project involves a complete roof replacement, including metal roof panels, fall protection devices, skylights, gutters, downspouts, and wall panel replacements. The scope includes removing existing metal panels and underlayment, inspecting and replacing up to 5% of the wood deck (6,375 sq ft), installing a high-performance self-adhering underlayment, and implementing a standing seam metal roofing system with specific technical requirements.
The project specifications detail precise technical requirements for materials, including galvalume steel panels, anchor clips, fasteners, and accessories from manufacturers like Garland Company, Inc. The roofing system must meet stringent performance standards, including wind load capacities, thermal expansion tolerances, and water infiltration resistance. The contract includes a 40-year, no-dollar-limit warranty, with installers providing a 2-year warranty covering roofing system installation and water-tightness. Additional components include fall protection devices meeting OSHA and ANSI standards, plastic glazed skylights with specific performance characteristics, and clearstory wall panel replacements, all to be color-selected by the owner.

PRCF Roof Replacement Background/Statement of Work
Background- PRCF is a minimum-security facility located at 3600 13th Street, Baker City which opened November 9, 1989. PRCF serves as a transition and re-entry facility for DOC. The metal roof system is from original construction and after years of snow and ice amongst other elements has reached the end of its life span. Wall panels between the roof levels of Support building are no longer watertight and are also in need of replacement.
Project- This project is for complete roof replacement along with gutters, downspouts, skylights, snow retention system, and life/safety anchor system. The replacement of the wall panels between the roof levels of support building is also included in the scope of work for this project.
Included in the base bid is 5% replacement of wood deck, 6,375 sq ft.
