Utilities to the Site are provided by:

Boiler Plant and Heating Systems

The Site’s general heating is provided by steam and hot water. The HVAC equipment includes various air handlers, air conditioners and unit heaters. Baseboard heating is also utilized in some building areas.

Steam is produced via three, gas and oil fixed boilers:

The newest low-pressure boiler is configured to run on either natural gas or #2 fuel oil, which is available via a 5,000-gallon aboveground tank. The high pressure boiler and one of the low pressure boilers fire on either #6 fuel oil or gas. The #6 fuel oil is held in a 20,000-gallon above-ground heated storage tank.

The boilers use softened water that is de-aerated and heated before entering the boiler drum. The Site’s normal heating load is accommodated by one or both of the low-pressure boilers.

Steam is circulated to each Building and local heat exchangers use the steam to heat water for heating and domestic use.

Compressed air is produced by a 250-scfm centrifugal unit located in Building I. The air is then cooled to 37°F to eliminate moisture and is piped throughout the Site. A 500-scfm centrifugal compressor provides stand-by support. The current site demand is approximately 150-scfm.

The Site’s natural gas enters the buildings at 10 psi. The cafeteria runs on a separate gas service line. A 50scfm centrifugal compressor provides standby support. The current Site demand is approximately 150-scfm.

Liquid nitrogen is stored in an 11,000-gallon tank adjacent to Building E. Liquid nitrogen is transferred to dewars and delivered to various labs for research use. The liquid in the main tank is allowed to expand and warm to ambient temperature. The gas pressure is maintained at 80 psi and it is piped throughout the Site.

A small de-ionized water system and several vacuum systems provide bench services in some of the buildings.

Chilled Water Plant and Cooling Systems

The Site’s central air conditioning system is substantially supported by two chiller plants. The generated chilled water is distributed through the piping system to the air conditioning units in each building (45°CHWS).

Chiller Plant #1
The Building I tunnel has an 800-ton Trane centrifugal chiller plant, which was installed in 1997. It is located in the tunnel link to the east of Building C. It uses HCFC-123, a refrigerant. The chiller is coupled to an all galvanized induced draft cross flow cooling tower that sits outside the mechanical room on grade. Chilled water pumps, condenser water pumps and related piping are all in excellent condition. This chiller plant services the needs of Buildings A (1st floor), B, C, D, G and H.

Chiller Plant #2
Also housed within Building I is a 1,000-ton Trane centrifugal chiller. The chiller is coupled to an induced draft cross flow cooling tower that sits outside the tunnel link mechanical room on grade. The chiller plant services the needs of Buildings C, D, E, H and G.

An additional 200-ton air cooled chiller supplies about one-half of the cooling requirements for Building J.

The two large chillers are controlled by a Trane Center Automation System. A gateway allows access to the Siemens Central Control System.

Building HVAC Control System

There is a DDC automation system controlling the HVAC system for the buildings. The user interface computer station is located adjacent to the boiler room in Building D. The system was manufactured by Landis and Staeffa. The system monitors and controls various equipment serving or located in Buildings A, B, G and H including all air handling units, both chiller plants including cooling towers and chilled water and condenser water pumps, related exhaust fans as well as the hot water converter in Building A and its related pumps. The chillers and accessories are controlled by Trane’s control system.

The two controls have been integrated to control and monitor all portions of the facility.

Dual high voltage(34kv) lines run along the abandoned railroad line. GPU transformers adjust the 34kv to 4,160 volt, 3 phase, on site. Utility metering is located after the step-down transformers, which are located in Building X. Total capacity of the transformers is 6,250 kw. The maximum demand currently at the Site is approximately 3,800 kw.

Individual transformers at each building step down power to 480/277 volts. Buildings D, I, J and L have dual feeds and transformers, which is used to supply electricity to motors and other large equipment. The 480v power is distributed throughout the buildings supplying electricity to large equipment and meters. Area transformers further reduce voltage to 120v for lighting and receptacles.

There are three diesel emergency generators on site.

Site lighting consists of building and pole-mounted fixtures; exterior light fixtures are high-pressure sodium units. Interior lighting is provided via high efficiency electronic ballasts and T-8 low mercury bulbs.

Domestic water enters the site via a 10” water main, which is located on the west side of the property. Water is delivered at 80 psi to 90 psi.

Piping consists of copper or cast iron in addition to PVC waste and vent piping.

The domestic hot water for sinks is generated by steam in Buildings B, C, D, E, G, H and I, which were installed in 1999. In Buildings A, J and L, hot water is generated by electric hot water heaters. In Building K, two, natural gas-fired water heaters are used.

Office Wiring

All offices are equipped with one voice and two data ports. The cabling runs as follows:

Voice

There is a PBX system from Avaya. Celanese leases the switch and Avaya provides the maintenance. There is ISDN presently through PBX (copper) as well as fiber. The entire phone system is monitored by AT&T. The PBX system characteristics include:

There is also an Audix system in place – Audix voice messaging, which uses a USL UNIX system. The Audix system characteristics are:

Data

There is a fiber network configured to support 56 T1 lines and is capable to support T3 lines. The fiber network connects to Verizon’s OC3 fiber facility capable of supporting total bandwidth of 155 mbps. There is also an AT&T Frame Relay network connecting the Summit Site through the WAN to all remote sites and a T1 line serving as backup to the Frame Relay. The Site has the infrastructure for remote dial-in and a number of conference rooms have wireless access points for wireless dial-up.

Video Conferencing

The Site is equipped with four Picture Tel video units and has video conference rooms wired for video. All video units are capable of transmitting and receiving 1 x 384 kbs. All units are switched through a dedicated MUX using dedicated T1 and 3BRI lines. The MUX automatically senses incoming video calls and connects at the appropriate speed. The video system is capable of transmitting or receiving four video conferences simultaneously.

The fire suppression system is supplied via a 6-inch fire loop off the street main. This line runs through an underground meter vault that contains a 6-inch detector check and valve. From this meter vault, a 6” fire line runs down the access road to a valve pit positioned in front of the west parking lot. The line then splits to a 3” fill line, which runs to the 100,000-gallon underground storage tank that functions as backup bulk fire protection water suction supply for the fire pump that is capable of delivering 1,250 gallons per minute. This fire pump is positioned in a pump house adjacent to the cistern and contains an electric motor driven fire pump for system pressurization. There is a jockey pump that maintains systems pressure. The municipal waterworks system is capable of supplying both the required flow and pressure necessary for the Site’s fire protection systems.

The Site’s fire protection loop encircles Buildings A, B, C, D, E, G and H and is sectionalized using post indicator valves. The loop supplies both building risers and fire hydrants, which are located throughout the site.

The Site is protected by a wet sprinkler system, which encompasses all the Buildings except in a few isolated rooms. Fire extinguishers (wall mounted) are throughout the buildings.

Emergency lighting and exit lights are powered by emergency battery units. The fire alarm system is a hard-wired system (ADT #4520). Alarm initiating devices and coverage varies by building (manual pull stations, duct detectors, horn/strobe in all buildings). The system also monitors the sprinkler system. There is a municipal tie-in circuit. The system is monitored on-site and off-site 24 hours a day.

The Site is equipped with a card reader security system and a system of interior and exterior CCTV cameras throughout the site. The security station is manned 24/7. A chain link fence secures the Site’s perimeter.
