Specifications:

1. Section 01000 Keesler Paragraph 2.1-A: Omit Paragraph and insert:

“A. The warehouse areas of the building will remain functional and operational; the office areas in the south end of the building shall be vacated for this project. Rm 128 and adjacent office shall be occupied with PAE supplying temporary air. The room shall be prepared immediately in project.

The existing ceiling and lights shall be removed, insulation disposed of, any devices temporarily wired out of way, and the existing plywood deck above removed. The existing fencing above shall be rolled back as contractor deems necessary to perform work. The attached condensate drain will be rerouted or lowered to allow access. With chillers down the unit served by the drain will be inactive. Currently the room has steel bar joists four foot on center with 2x4 stringers bolted on top with the plywood (rotted) attached to stringers.

Remove the split system unit associated with the space in its entirety.

Contact HVAC shop to retrieve refrigerant prior to demolition. Replace all plywood with new ¾” CDX screwed to new stringers on 16” centers. Deck shall completely cover the offices below. The deck will serve as a work platform and allow work above occupants for safety. However, schedule removal of return fan at a time when occupants are not there as this is a heavy unit. Upon completion of deck return inside and install new lights, grid, 6” batt insulation on ceiling tile, and do not install grilles at this time. Once the new main ductwork above is ready for operation with new air handler and chill water system operational, then return to Rm 128 and adjacent office to install the VAV boxes, supporting ductwork, grilles, and the controls. It will be necessary to cut holes in deck for grilles. Minimize hole sizes and number of holes where possible. The fencing above with condensate drain will be restored. PAE will then remove temporary cooling.”

2. Section 01000 Keesler Paragraph 3.1-A: Omit Paragraph and insert:

A. “It is the intent of this project to completely renovate the HVAC system serving the office areas of the building. The existing chill water system and the chillers shall be completely demolished with subsequent replacement. The entire airside side shall also be demolished and replaced with a new VAV system.

The heating system shall remain less the small heating water pump currently serving the offices. A new pump with accessories and connecting piping shall be installed. Exterior work shall occur to re-pipe the chillers with a reverse return system. All asphalt shall be replaced as currently shown by plans. All unused penetrations into the warehouse shall be sealed for 2 hour fire ratings.

All ductwork penetrating wall shall be fire protected with a damper per UL standards. There are several penetrations that will be enlarged using a concrete saw. The office areas will be vacated for this project. Additional offices occur in the warehouse area along south wall that currently has ductwork and piping to be removed over and in it and will be included in work.

The main ductwork and hot/chill water piping will be extended through the warehouse south end over those existing offices. A new plywood deck will be installed over Rm 128 and the pickup/delivery office. This work shall occur first as this office will immediately be used as an occupant rotation space. Provide tarps over weapons storage and storage that may remain to insure accidental flooding does not occur. The contractor shall coordinate work in those areas for access. The security fencing above the warehouse offices, in way of work, shall be removed and restored to allow access to existing ductwork and piping as well as installation of new. Also, a future chill water loop will be added through the warehouse area. That area will be occupied and all work must be coordinated for access as this is a secure area. “
