1.3 PROJECT BACKGROUND AND SCOPE

1.3.1 Background

1.3.1.1 General

A functional fire protection system is a priority requirement for the U.S. Army Garrison Natick - Natick Soldier System Center (NSSC). The existing Simplex Fire Alarm system’s fiber optic lines are approaching 25 years of age and the existing fire panels are nearly 15 years old. Recent tests show fiber strands degraded in various areas, crushed conduit, open lines around buildings, lines that have been completely removed in various sections, intermittent signal problems between buildings, and a list of other abnormalities. Additionally, Johnson Controls/Simplex has notified the Garrison that they will no longer be able to support repairs due to the status of the existing fiber lines. Parts for panel repairs are becoming increasingly difficult to find and the Garrison has been forced to use/recycle system components from existing panels across installation that are in process of demolition or removal. Given the condition of the existing fiber loop, NSSC has determined that either system wide repairs must be conducted or some alternate means for ensured reporting is required.

The fire alarm system ultimately “belongs” to NSSC’s Department of Public Works (DPW) for installation, operation, maintenance, and repairs. The U.S. Army Corps of Engineers (USACE) New England District (CENAE) is currently working on fire suppression upgrades for several buildings across the Garrison, but relevant guidance/regulations require that all signals must be able to report locally once in place. Therefore, DPW has requested CENAE’s support to address the failing system and to make necessary panel/system upgrades/replacement/repairs.

It was determined that a decoupled, wireless fire alarm system was preferred by NSSC. The new system would require a minimum of 2 receivers, 2 decoders, and wiring - with wireless (mesh) connectivity that allows system transmission interlink (crosstalk). This type of system offers flexibility in installation, maintenance and repairs since each system component operates independently minimizing system-wide impacts/outages during installation, maintenance, or repairs. This type of system will support a phased construction approach rather than requiring a comprehensive site-wide system installation effort, which would be cost prohibitive.

NSSC - Base Wide Fire Alarm Transmission Natick, MA

The purpose of this project is to provide Soldier Systems Center at Natick, Massachusetts, a reliable and code compliant means of transmitting fire alarm signals from existing fire alarm systems located in individual buildings to a central receiving station located in Building 1. Currently, Natick uses a fiber optic cable loop to connect their Simplex fire alarm panels to the existing Simplex central receiver. This loop is not fully functional; there are five (5) legs in the loop that are non-functioning and unable to transmit and there are four (4) building fire alarm panels which have not yet been connected to the loop.

The Contractor must design and install a radio transceiver system that consist of transmitter panels and antennae at each building and central- station receiving equipment in Building 1. This system must be totally independent of the existing system and constructed in parallel without affecting the existing system’s operation. The existing Simplex receiving equipment and fiber optic cabling/equipment must not be demolished until the new radio system is operational and formal acceptance testing is complete.

1.3.6 Mechanical (HVAC) Scope of Work

1.3.6.1 General

An existing equipment closet located within the basement of Building 1 contains multiple data racks that require continuous cooling. The closet is currently cooled via a blower coil unit connected to a chilled water system. Natick staff has communicated that the closet has had difficulty to maintain a set point of 75˚F and has questioned the capacity and performance of the existing blower coil unit. The chilled water distribution system currently serving the blower coil unit is currently being primarily controlled to cool the adjacent police station. The supply chilled water temperature is currently being adjusted to accommodate the cooling loads of the police station. The closet is currently ventilated by an exhaust system that pulls air from the corridor via existing door intake louver.

As part of this project the chilled water system controls and system flows are to be modified as required to allow the blower coil unit to operate in a greater capacity and provide sufficient cooling to the closet. The entire chilled water system and blower fan coil unit are to have TAB performed pre- construction and post construction.

The existing exhaust air system is currently not operating due to a broken belt on the fan. The fan belt is to be replaced and the overall system is to have TAB performed pre-construction and post-construction in order to confirm ample air changes are occurring within the closet. A new fire rated entry door will be installed in order to achieve a 2-hour fire rating for the closet. The new door is to have a compliant door undercut in order to allow for transfer air into the space.

1.3.6.2 Mechanical (HVAC) Existing Conditions

The existing closet has a suspended horizontal 2-ton blower coil unit that is fed via a chilled water loop that is dedicated to the campus police station. The existing unit has a 1/3 HP blower fan. The unit drains condensate to a floor drain located on the floor below the unit. Natick staff has communicated that the current blower coil unit is unable to maintain a desired 75˚F setpoint during the summer cooling season. Upon further discussion with Natick staff, it was communicated that the operational temperatures of the chilled water loop tend to vary as they are controlled primarily for comfort cooling of the adjacent police station. The current piping connection which is believed to be located at the end of the

NSSC - Base Wide Fire Alarm Transmission Natick, MA circulation loop looks to not currently contain the ability to allow for bypass flow.

There are two data rack radiant cooling panels and associated modulating controls box located within the space that are not in use. The radiant cooling system used to also be connected to the same chilled water system. Natick staff have communicated that the systems were ineffective and can be removed as part of this project.

The closet contains the end of two exhaust duct risers. The first riser has a large tap to an exhaust grille that is on the other side of the closet wall that serves the adjacent atrium space. The first riser also has a tap for a spiral duct that runs through the space to the opposite wall where it penetrates the wall and serves room exhaust for the adjacent mechanical room. The second riser has an opening for exhaust out of the equipment closet. The exhaust duct risers are believed to route back to a roof mounted exhaust fan. The fan motor is currently operating but the fan belt is broken therefore the fan system is not currently operating.

The entry door currently contains an intake louver located on the lower portion of the door to allow for air intake to the closet.

1.3.6.3 Mechanical (HVAC) Demolition

a) Make exothermic welds strictly in accordance with the weld manufacturer's written recommendations. Welds which are "puffed up"

NSSC - Base Wide Fire Alarm Transmission Natick, MA or which show convex surfaces indicating improper cleaning are not acceptable. Mechanical connectors are not required at exothermic welds.

Make high compression connections using a hydraulic or electric compression tool to provide the correct circumferential pressure. Provide tools and dies as recommended by the manufacturer. Use an embossing die code or other standard method to provide visible indication that a connector has been adequately compressed on the ground wire.

1.3.9 Fire Protection

1.3.9.1 General

The purpose of this project is to provide Soldier Systems Center at Natick, Massachusetts, a reliable and code compliant means of transmitting fire alarm signals from existing fire alarm systems located in individual buildings to a central receiving station located in Building 1. Currently, Natick uses a fiber optic cable loop to connect their Simplex fire alarm panels to the existing Simplex central receiver. This loop is not fully functional; there are five (5) legs in the loop that are non-functioning and unable to transmit and there are four (4) building fire alarm panels which have not yet been connected to the loop.

The Contractor must design and install a radio transceiver system that consist of transmitter panels and antennae at each building and central- station receiving equipment in Building 1. This system must be totally independent of the existing system and constructed in parallel without affecting the existing system’s operation. The existing Simplex receiving equipment and fiber optic cabling/equipment must not be demolished until the new radio system is operational and formal acceptance testing is complete.

1.3.9.8 Firestopping Utility Penetrations

Any penetrations of fire-rated assemblies must utilize a fire-stop assembly or device that is UL-listed and FM-approved for a rating to match the penetrated assembly. The Contractor must also firestop all existing floor openings in the neighboring electrical room, including a large opening with multiple conduits.

1.3.9.9 Existing Conditions

Existing Receiving Equipment: The central receiving equipment is located in the basement of Natick Building 1. Two (2) fiber optic cables terminate at a Simplex Comark Model 06-UL864-002 Digital Alarm Communication Receiver (DACR) located in Room 035. The DACR is rack-mounted in a rack with spare space above and below. There are two Simplex desktop workstations. One workstation is located in Room 035 and the second is located across the hall in DES Dispatch Room 022.

Existing Vertical Raceway in Building 1: There is an existing vertical raceway on the corridor side of the Stair 3 wall. This raceway is recessed into the CMU block wall with a removable steel cover and runs the full height of the building.

Existing Fire Alarm Control Panels and Transmitters: The existing fire alarm control panels have Digital Alarm Communication Transmitters (DACTs) capable of sending fire alarm signals through the fiber optic pathway to Building 1. The existing panels are all Simplex panels (only Simplex panels can be connected to the fiber network). The majority of the panels are Simplex 4200U model and were installed in 2006. See Table 1.3.12-1.

NSSC - Base Wide Fire Alarm Transmission Natick, MA

Existing Fiber Optic Loop: The fiber optic loop pathway is shown in Fig. 1.3.9-1 below. The red shaded areas are legs of the fiber loop that are currently non-functioning (there are five legs currently inoperable). Also shown in Fig. 1.3.9-1 are the four (4) existing fire alarm systems not currently integrated into the campus fiber optic loop. As a result of the above issues, many buildings on campus cannot send fire alarm signals to B1 at this time.
