About this file
This Addendum No. 1, issued by the Technical College System of Georgia on behalf of Albany Technical College, modifies the original bidding documents for the Randolph County Learning Center AHU (Air Handling Unit) Replacement project dated March 14, 2023. The project involves the replacement of an air handling unit at Albany Technical College's Randolph County Learning Center located at 241 Highway 82 East in Cuthbert, Georgia. A mandatory prebid conference and site visit were held on April 13, 2023, at 10:00 a.m. EST at the Albany Campus in Room 106 of the Randolph County Learning Center. This addendum, effective April 17, 2023, establishes modifications to the contract documents and must be acknowledged by bidders on the bid form to avoid disqualification.
The addendum amends Section 01 4000 (Quality Requirements) by identifying three approved contractors qualified to bid on this project: Albany Air, Apex Facility Services, and SafeAire. Additionally, Sheet E201 was revised to include new electrical work notes for the condensing units, specifying requirements for new conduit and wire connections to existing disconnect switches, voltage conversion through a new variable frequency drive (VFD), automatic volume dampers, circuit extensions, and new 60-ampere fused disconnect switches with proper feeder sizing. The electrical modifications include reusing existing feeders where applicable and connecting new equipment to the main service board through the mechanically located VFD.
