GENERAL DESCRIPTION OF WORK

Scope of Work Summary

• Modifications to the existing building(s) sprinkler piping systems in conjunction with architectural and electrical/mechanical modifications to existing room spaces for the purpose of building out new Telecommunication Rooms (TRs).

Design Criteria & Code Basis

• The following evaluation and recommendations for fire protection for this project are based on requirements of the Eighth Edition of the VA Fire Protection Design

Manual (VAFPDM), NFPA 101 - Life Safety Code (2021 Edition) and the current editions in effect for the remaining NFPA codes and standards applicable to the scope of this work.

• The level of rehabilitation work under this project will be modifications based on the reconfiguration of the existing spaces identified for build-out as new or modified TRs. The existing means of egress for spaces outside of the areas of work will not be altered and will remain usable during the course of this project.

• Telecommunication Rooms (TRs) are required to be protected with wet pipe automatic sprinkler protection per Section 3.7.C of the VAFPDM. Quick response sprinklers are permitted for TRs.

• All sprinkler pipes in TR’s will be painted Red.

• Section 3.7.E of the VAFPDM does not require smoke detection coverage for

TRs. The designated new TR spaces are not typically arranged with smoke detection coverage. Per request of the Fargo VAHCS, smoke detection is being specified for each TR space. TR Room smoke detectors are being specified as supervisory alarm devices per the direction of the Fargo VA. New dedicated space cooling units will be provided in each TR. These units will serve the TR only and do not require duct smoke detection.

(Cont’d) Design Criteria & Code Basis

• The fire alarm systems will be required to be placed on test status in accordance with the facility impairment procedures during work on the automatic sprinkler systems.

Sprinkler Systems

• The existing building automatic sprinkler installations are observed meet the requirements of NFPA 13 and VA guidelines. Existing quick response, semi-recessed pendent or upright sprinklers are typically installed throughout the areas of work.

• Buildings 10, 11 and 13 are to have data racks installed in existing sprinklered room spaces. No modifications for sprinklers are required for these spaces.

Building 56 is a non-sprinklered building. Additional smoke detection is not specified for these spaces.

• Existing sprinkler locations in new TR spaces will be relocated, where required, for compliant coverage for the new configuration of rooms. Relocation of sprinklers will require reworking existing sprinkler piping. Existing sprinkler branch lines will require modifications outside of the rooms of work only at locations noted on the drawings. Where applicable new sprinklers will be added to existing modified branch lines to provide compliant coverage per NFPA 13. All new or relocated (new) sprinklers will be upright quick response type installed with UL listed sprinkler guards. Sprinkler piping will be relocated where practical to not be located directly above the locations designated for new TR equipment racks.

• Sprinkler modifications indicated include maintaining compliant sprinkler coverage outside of the TR rooms in adjacent spaces where existing wall boundaries are altered.

• Several of the new TR spaces to be modified have suspended ceilings and are arranged with pendent sprinklers. All finished TRs will be open to the deck with no suspended ceilings.

• Sprinkler work will be specified to modify TR space sprinklers to the upright position prior to the removal of suspended ceiling tiles to maintain compliant sprinkler coverage of the room during the period of construction. This approach may require a second stage of piping modifications to occur for completion of a final sprinkler coverage coordination with the mechanical/electrical changes to occur.

• The scope of this work specifies sprinkler piping modifications required for compliant protection for existing TRs which will be abandoned. Changes in these rooms consist of alterations or removal of existing suspended ceilings.

• As noted above, modifications to the existing sprinkler piping systems consists of modifying a limited amount of sprinkler piping in each area of work. The hydrostatic testing requirements for the sprinkler system modifications will be specified to be conducted at the system working pressure in lieu of the 200 psi hydrostatic test pressure required for new piping systems as permitted by NFPA

13: 29.7.

• The piping modifications required for this scope of work will not alter the hydraulic characteristic of the existing sprinkler system coverage for the space.

Hydraulic calculations will not be specified to be submitted for this work.

Portable Fire Extinguishers

• The VAFPDM Section 3.7.E requires each TR to be provided with a CO2 or clean agent type fire extinguisher. The extinguishers are required to be located outside of the TR in semi-recessed cabinets to be accessible for inspection and maintenance, within a 75 feet travel distance of the room. 6-2

LIFE SAFETY

Egress

• The areas of work will occur in rooms which open to health care corridors or in business office areas. The access to existing required exits will not be affected by this work.

Compartmentation

• The project scope of work requires all TRs to be enclosed within 1-hour fire barriers per direction of the Fargo VA.

• Typical health care corridor walls which adjoin the TR spaces are constructed of materials to meet the performance for a 1-hour fire barrier rating. Existing walls in business areas are typically not identified as fire barriers, however existing construction of materials observed also meets the performance for a 1-hour fire barrier rating.

• This project requires existing walls that enclose all TRs which do not currently extend to the deck above to be infilled with a 1-hour fire barrier extending to the floor assembly or roof assembly above the TR.

• New TRs will be provided with new access door openings. TR door openings

(new and existing) require a minimum 45-minute rated self-closing fire door and frame.

Firestopping

• Firestopping for new and existing horizontal and vertical penetrations in all TR floors, ceilings and walls will be implemented. Additionally, routing of new cabling outside of TRs through fire rated floors requires firestopping.

• All penetrations into the TR’s are to be an assembly that will allow 100% fill and be easily adjusted for new cabling and removal of old. Size and number of assemblies should be designed at 60% fill, when project is complete. All four walls should have at least (1) assembly. GC should fill all existing unprotected openings.
