1.2 SYSTEM DESCRIPTION

The intent of this specification is to define the DDSP Installation requirements associated with the inspection, testing, and repair of fire suppression systems.

Work on fire suppression systems will vary depending the Inspection, Testing, and Maintenance cycle required in the contract’s statement of work document and exhibits. In some cases, problems will require verification through further inspection and testing.

Contract drawings provide specific locations of each building on the depot, specific locations of each system within a particular building.

At the conclusion of repair activities, including inspection, repair, and/or replacement, systems will be tested to confirm that they function within acceptable parameters as defined in NFPA 25. Coordinate final testing with COR. Installation Fire Inspector is to be present for each fire sprinkler system acceptance test.

Government approval is required for submittals with a "G" designation; submittals not having a "G" designation are for Contractor Quality Control Approval. Submit the following in accordance with Section 01 33 00 SUBMITTAL PROCEDURES:

SD-06 Test Reports Impairment Worksheets; G Final Acceptance Test Report; G

Three copies of the completed Final Acceptance Test Reports no later than 7 days after the completion of the Final Acceptance Tests. All items in the Final Acceptance Test Report shall be signed by the Fire Protection Specialist.

1.4 DELIVERY, STORAGE, AND HANDLING

Equipment brought on-site may be stored at the contractor’s dedicated location in Building

750. This equipment should be secured by the contractor at the location for security purposes.

Section 21 95 00.00 10 – Fire Sprinkler System Repairs Page 5 of 19

Deliver equipment and materials to the site in an undamaged condition. Material that is deemed to be damaged or defective by the Contracting Officer from manufacturing, during shipment, or while on-site shall be replaced at the Contractor's expense. Equipment and materials that are deemed to be damaged or defective shall be removed and properly disposed of by the Contractor. New equipment and materials shall be utilized to replace rejected materials or equipment.

Contractors shall receive material and equipment at their own facility and transport this equipment to the Installation and project site themselves. Government is not responsible for damage to material and equipment shipped directly to the Installation. Contractor must be present to accept shipment of material directly to the Installation. Material that is shipped to the main warehouse (Building 2001) can easily be lost in the midst of the large volume of material constantly moving through the receiving warehouse. Material that is shipped to the Installation and subsequently lost shall be replaced at the Contractors expense.

Store materials off the ground with drainage to avoid standing water and provide protection against ground moisture and dampness. Store materials with a moisture barrier at both the ground level and as a cover. Stored items shall be protected from the weather, humidity and temperature variations, dirt and dust, or other contaminants. Proper protection and care of all material both before and during installation shall be the Contractor's responsibility.

During shipping, delivery, and installation, piping and similar openings shall be capped to keep out dirt and other foreign matter.

1.5 PROJECT / SITE CONDITIONS

This project will involve the inspection, maintenance, testing, and repair of systems in buildings throughout the entire site. All of the buildings currently present on-site are active and in constant use. Coordination with site personnel through the COR needs to occur on a daily basis to achieve a successful project.

1.6 ACCESSIBILITY OF WORK

The majority of alarm valves on the installation are located in sprinkler valve houses separated from the main warehouse storage area. However, in a few buildings, the systems are located at the perimeter of the warehouse area. Warehouse sprinkler piping is located above floor and rack storage. Warehouse storage areas have constant activity on a daily basis. The site is a 24 hours a day, 7 days per week operation. Coordination with site personnel through the COR will be critical to minimize the impact on DDSP operations and maximize the effectiveness of the work crews trying to get work done in these areas.

PRODUCTS

2.1 STANDARD PRODUCTS

Materials and equipment shall be standard products of a manufacturer regularly engaged in the manufacture of such products and shall essentially duplicate items that have been in satisfactory use for at least 2 years prior assignment of the specific project. Replacement of existing components, modification of existing fire sprinkler systems, addition to or extension of existing fire sprinkler systems, and new parts on existing systems shall comply with the

Section 21 95 00.00 10 – Fire Sprinkler System Repairs Page 6 of 19 applicable specification section for the type of system on which the parts shall be installed including Section 21 12 00, STANDPIPE SYSTEMS; Section 21 13 13; WET PIPE SPRINKLER SYSTEMS, FIRE PROTECTION; Section 21 13 16, DRY PIPE SPRINKLER SYSTEMS, FIRE PROTECTION; Section 21 13 18, PREACTION SPRINKLER SYSTEMS, FIRE PROTECTION; Section 21 13 19, DELUGE SPRINKLER SYSTEMS, FIRE PROTECTION; Section 21 23 00.00 20, WET CHEMICAL FIRE EXTINGUISHING FOR KITCHEN CABINETS; and Section 21 30 00, FIRE PUMPS.
