About this file
This Addendum 2, dated June 6, 2022, modifies the original specifications and drawings for the Morningside Elementary School HVAC and Plumbing Upgrades project being undertaken by the Dougherty County Board of Education in Albany, Georgia. The addendum establishes modifications to three specification sections related to HVAC closeout documentation requirements, instrumentation and control systems, and particulate air filtration with bipolar ionization units. Three mechanical demolition plan drawings (MD101, MD102, and MD103) covering sectors A through E are revised and replaced in their entirety. The addendum includes a mandatory pre-bid meeting scheduled for June 23, 2022, at staggered times beginning at 12:45 p.m., with the location at 601 Flint Ave, Albany, Georgia. The pre-bid sign-in sheet documents attendance from multiple contractors and vendors representing various mechanical, electrical, and construction firms across the region.
Key specification changes include the replacement of HVAC closeout document requirements with a transfer form for spare parts and materials, specifically requiring the provision of one cylinder of R-410a refrigerant. New instrumentation requirements mandate that the direct digital control system monitor fault outputs from all bipolar ionization units, with alarms transmitted to the owner's control system. Additionally, all particulate filtration units must be equipped with dry contact output capability for building automation system fault condition monitoring. All bidders of record are required to acknowledge receipt of this addendum on the Bid Price Form, with failure to do so subject to disqualification from the procurement process.
