About this file
This document contains a specification for resilient sheet flooring and related accessories for the Lexington VAMC project to replace flooring and doors in the Emergency Department at the Troy Bowling Campus. The specification includes requirements for welded seam sheet flooring made of rubber or vinyl with a smooth wear surface and minimum thickness of 1mm for the wear layer. Accessories such as bonding chemicals, welding rods, adhesives, edge strips, and sealants are also specified. The specification provides information on applicable standards, submittals, quality assurance, delivery and storage, field conditions, and warranties. It details preparation work, installation methods for the flooring and integral cove base, and procedures for heat or chemical welding of seams. The specification concludes with sections on cleaning, protection, and repair requirements.
The related federal contract opportunity is a solicitation for project 596A4-19-108 to replace the flooring in the Emergency Department at the Troy Bowling Campus of the Lexington VAMC in Lexington, Kentucky. The scope of work requires the contractor to prepare the site, demolish and remove existing doors and flooring, and furnish all labor, materials and equipment to install new doors and flooring per the drawings and specifications provided. The justification given is that the current ED flooring is damaged with holes and cracks throughout and needs replacement to avoid injury to patients and staff. The contracting agency is listed as the Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 9.
