About this file
This document is a technical specification for Section 06 10 00 Rough Carpentry, which is part of a larger federal contract opportunity.
The specification outlines the requirements for wood blocking, sheathing, furring, nailers, and rough hardware to be used in the construction project. It provides details on the performance requirements, submittals, product delivery and handling, applicable industry standards, and installation procedures for the rough carpentry work. Key requirements include using lumber and plywood products that meet certain grading and moisture content standards, utilizing waterborne or boron-based wood preservatives, and following specified installation methods for sheathing, blocking, nailers, and furring. The specification also includes requirements for biobased content in the lumber and plywood products. This technical specification supports the broader federal contract opportunity to repair a Committal Shelter, Columbarium, and Perimeter Fence at a National Cemetery facility.
