About this file
This addendum modifies drawings and specifications for a project to improve exhaust systems at the Cincinnati VA Medical Center. The revisions include changing the outside air supply configuration for several fan coil units by deleting duct connections to return air ducts and adding new duct branches and ceiling diffusers to individual rooms. The schedules are also updated to remove the outside air CFM column from the fan coil unit schedule and add information to the air device schedule.
The related federal contract opportunity is a solicitation to correct fire code deficiencies and interior deficiencies at the Cincinnati VAMC. The project value is between $500,000 and $1,000,000. The solicitation will be set aside for a service-disabled veteran owned small business. Interested offerors must register on the Vendor Information Pages and SAM websites. The NAICS code is 238220 and size standard is $16.5 million. The duration following notice to proceed cannot exceed 180 days. Payment and performance bonds will be required.
