1. DESCRIPTION OF SERVICES.

The contractor shall provide supervision, labor, material and equipment required to perform all work for the following project: CAD 1 REPAIR FIRE PROTECTION SYSTEMS. Report any unforeseen findings to the attention of the

Contracting Officer Representative (COR) assigned to the project. The COR is the individual designated as the authorized representative of the Contracting Officer. The COR is responsible for monitoring the performance and technical management of the effort required and should be contacted regarding questions or problems of a technical nature. The COR will be the construction manager (CM), engineering technician (ET), and/or performance assessment representative (PAR) assigned to the project. Materials mentioned herein shall be the same or equal to specified manufacturer and or in quality.

Many of the inert warehouses at Yorktown and Cheatham Annex were built in the 1940’s, and the fire protection systems are dated. They have been a source of continuing maintenance problems. The buildings included in a study performed by the AE firm GHD are grouped by similar style and construction, those being Yorktown Buildings 479-

485, CAD 1-10, CAD 11-16, and CAD 30. In addition, the AE firm GHD designed CAD 2 Repair Fire Protection

Systems, which will remove and replace the existing fire protection system and install a site fire pump for CAD 1-16 in the rear of CAD 2.

The buildings CAD 1-10 are located between B and D Streets, on the northwest side of Sanda Avenue, at Cheatham

Annex. The facilities were constructed in approximately 1943 as warehouses with four bays, which are currently occupied and used for storage. They are single-story structures utilizing wood columns and trusses in most bays, with some buildings having steel trusses in certain bays. The buildings have painted CMU (concrete masonry units) exterior walls, CMU fire separation walls and a concrete floor slab. A modified bitumen roofing system covers the roof deck, with several of the roofs recently replaced. No central heat or cooling system exists. Self-contained modular office units have been located in some of the buildings to provide offices for the tenants. Restrooms and small offices are located in the buildings. CAD 1-10 are protected by a working dry-pipe sprinkler system; four valve rooms are attached to the north or south face of the building – one per bay. The gross floor area is approximately

101,475 square feet (SF) each.

Cheatham Annex system pressure for the entire complex is obtained from the existing water tank CAD 637, which was designed in 2012 and constructed in 2013. The design included a separate elevated tank in the warehouse area;

2 | P a g e however this tank was never built. Cheatham Annex is a little over 20 square miles with recreational facilities, bachelor housing units, training functions, administrative functions, and an industrial functional area, which includes a number of warehouses. The industrial/warehouse area is central to CAD 1-16 and CAD 30. This is one of the largest building areas for fire flows and but also has the smallest demand for domestic water. The domestic water system, when separated from the fire protection demand in the warehouse area, will still serve the warehouse area domestic needs in addition to all of the needs of the remaining buildings on Cheatham Annex. Current total domestic water demand for Cheatham annex is approximately 50,000 gallons per day (GPD).

The current water system at Cheatham Annex utilizes two (2) 2 inch water lines located close to the church on

Penniman Road near CAD 637 for makeup water. Adjacent to the church is a 16 inch water line on York County property. Also, at the intersection of Hawk’s Nest Drive and Penniman Road is a 12 inch water line on York County property.

This scope of work is to repair the fire protections systems in CAD 1, based on the design and study of the AE firm Fisher.
