SUMMARY PURPOSE AND SCOPE:


This project will provide the restoration of the Flight Systems Research Laboratory, Building 
210, to support important national research programs.  Work includes restoration of the HVAC and 
electrical power systems, structural reinforcement to meet seismic code requirements, removal of 
hazardous materials, and restoration of the building's exterior surfaces.  Also included is the 
rehabilitation of existing office, lab, shop, and service space on two floors and construction of 
additional lab space within the interior of the building.



PROJECT JUSTIFICATION:


Building N-210 provides computer, office, and simulation lab space for important national 
research programs for NASA, the Army, Air Force, and the Federal Aviation Administration (FAA).  
These include the joint NASA/FAA program to upgrade the nationŐs Air Traffic Control (ATC) System 
and the joint Army/NASA RASCAL research helicopter project.  Additional laboratory space is 
needed for these expanding programs.  Restoration is critically needed to improve facilities and 
work environment required for these important programs, and to assure the safety, reliability, 
and performance of the electrical power, HVAC, and fire safety systems.  Presently, the facility 
uses excessive energy due to old HVAC equipment, poor windows, and inefficient energy control 
systems.  Building N-210 is the oldest structure at Ames Research Center, and numerous 
modifications over many years have fragmented the infrastructure, resulting in code violations 
and high maintenance costs.  Electrical transformers contain hazardous PCB materials.  Handicap 
access to the facility and existing restrooms do not meet code requirements.  Building corridors 
do not provide proper egress from the building, violating fire codes.


IMPACT OF DELAY:


Delaying this project risks injury to personnel during a seismic event or fire and continues the 
liability of using a facility with safety code violations.  Expanding programs will lead to 
additional crowding of personnel and equipment.  The failure of a PCB transformer would force 
vacating the building until a lengthy and expensive cleanup operation could be completed.

PROJECT DESCRIPTION:


The work will include the replacement of the existing building HVAC and electrical power 
distribution systems, restoration of the existing deteriorating exterior surfaces of the 
building, removal of hazardous asbestos and PCB materials in all areas, and provisions for 
handicapped access.  Seismic improvements will include new concrete shear walls within the 
building and installation of steel cord ties at designated floor diaphragms.


Two new 565 kW chillers will be added.  An ice bank stored cooling system will be used to provide 
redundant cooling capacity.  A two cell, low profile induced draft cooling tower and building air 
handlers will be added.  A new boiler will be installed.  All system controls will be connected 
to the Ames Facilities Management and Control System.


Office, computer lab, shop, and service areas on two floors of the building will be 
rehabilitated.  The interior of the building will be reconfigured to allow for an additional 650 
square meters of usable space.  Fire and safety systems will be restored with installation of new 
smoke detectors.  The existing automatic wet pipe sprinkler system will be expanded to all areas 
of the building.  Existing electrical switchgear and panels served by transformers T-75 and T-76 
will be replaced.

SUMMARY PURPOSE AND SCOPE:


This project provides for the restoration of major segments of the 
chilled water distribution system at the Goddard Space Flight Center 
(GSFC).  The project will replace underground piping that is aging and 
undersized, and install shutoff valves.


PROJECT JUSTIFICATION:


GSFC has experienced serious problems with the central chilled water 
distribution system.  The underground chilled water piping is 
approximately 30 years old and at the end of its expected useful service 
life.  The pipes and valves have deteriorated and are leaking 
substantially.  With the modernization of the central chilled water 
plant, the new secondary pumps will boost the pressure by 103 to 138 k 
Pa, which will add even more stress to the system.  Pipe sizes in 
several sections of the system are inadequate for existing as well as 
future design flow rates.  Some critical buildings do not have adequate 
redundancy in the event of a chilled water service failure.  This 
project will replace piping and upgrade the system.  Redundant circuits 
will also be provided to improve reliability.


IMPACT OF DELAY:


Delay of this project will result in increasing leakage and failures due 
to aging piping and increasing pressures.  Ongoing construction will 
place additional demands on the chilled water system and some portions 
of the system will experience flow deficiencies unless pipes sizes are 
increased.  As a result, some buildings will have inadequate chilled 
water quantities and air conditioning capacity.


PROJECT DESCRIPTION:


This project provides for the replacement of various segments of the 
underground chilled water distribution piping in the northeast, 
northern, and southern portions of the site.  In the northeast sector, 
two 305 mm pipe mains (supply and return lines) will be replaced from an 
area south of Building 24 to an area near the intersection of Minitrack 
and Tirus Roads.  In the northern and southern sectors, chilled water 
feed lines to Buildings 1, 2, 14, 18, 19, and 20 will be replaced.  The 
project includes all site work required for excavation, rerouting other 
utilities, backfill, and resurfacing associated with piping work.  
Asbestos insulation on existing piping will be removed to the extent 
that it is necessary to perform the work.

SUMMARY PURPOSE AND SCOPE:


The project will replace 12 obsolete, 25 year old chillers with state-
of-the-art chillers in Buildings 157, 161, 179, 180, 198 and 233.  The 
replacement units will use new alternative refrigerants which will 
comply with federal and state environmental regulations.  This project 
will also consolidate the chillers serving Buildings 161, 198, and 156.


PROJECT JUSTIFICATION:


The chillers to be removed are over 25 years old and are beyond their 
economic and mechanically useful lives.  They are unreliable, 
inefficient and difficult and expensive to maintain.  In many instances, 
repair parts are very hard to find or must be hand made.  The 
refrigerant which these obsolete chillers use is now environmentally 
unacceptable.  The replacement chillers will use environmentally 
acceptable refrigerants.  The obsolete chillers are too old for 
retrofitting with acceptable refrigerants.


IMPACT OF DELAY:


The Jet Propulsion Laboratory (JPL) will be forced to continue use of 
obsolete, deteriorated chillers which are costly to maintain and energy 
inefficient.  In addition, JPL will lose the opportunity to eliminate 
almost 4,500 kilograms of ozone depleting chlorofluorocarbons from 
routine use. 


PROJECT DESCRIPTION:


This project proposes to replace a total of 12 chillers in Buildings 
157, 161, 179, 180, 198 and 233.  New chillers will be water cooled, 
hermetic centrifugal type with non-ozone depleting refrigerants.  
Chiller size in each building will be reevaluated and adjusted to 
reflect the current or reasonably anticipated air conditioning load in 
that building or building complex.  Similarly, both condensing water and 
chilled water pumps will be checked and replaced as necessary to meet 
new chiller characteristics.  Chillers presently looped to serve 
Buildings 156, 161 and 198 will be concentrated in Building 161, 
retaining the pumps in Building 198.

SUMMARY PURPOSE AND SCOPE:


This project provides for replacement of obsolete primary electrical 
components and subsystems in the Johnson Space Center (JSC) main 
electrical substation (221) to assure continued, reliable, and safe 
primary electrical power distribution, and control for the main site 
operations. 


PROJECT JUSTIFICATION:


The circuit breakers, switchgear, and bus duct need to be replaced to 
eliminate weaknesses in JSCŐs main substation.  The primary switches in 
buildings 14, 16A, 36, and 419 also need replacement.  This equipment is 
increasingly jeopardizing site power, operators, and equipment.  
Replacement parts for most of this equipment are only available through 
cannibalization or custom fabrication.


IMPACT OF DELAY:


If this project is not approved, the reliability of the JSC electrical 
substation and overall site power will continue to deteriorate and 
increase the probability of equipment damage and interruptions to 
ongoing operations.  


PROJECT DESCRIPTION:


The project includes replacement of 12.5-kV switchgear(bus 2), 12.5-kV 
switchgear (bus3), five primary oil circuit breakers, and related 
interconnecting old bus duct.  An upgrade of bus-1 switchgear from 500- 
to 700-mVA capacity, replacing aluminum conductors in an existing duct 
bank, and replacing 15-kV switches at Buildings 14, 16A, 36, and 419 
will also be accomplished.

SUMMARY PURPOSE AND SCOPE:


This project provides for the refurbishment and service life extension 
of 15,000 Volt manually operated load break switches to eliminate 
explosive hazards associated with oil-filled switches.


PROJECT JUSTIFICATION:


The existing manually operated load break switches must be replaced for 
safety reasons.  The obsolete switches have a history of explosive 
failures which have injured and killed operating personnel.  Another 
reason for replacing the switches is the fact that replacement parts are 
no longer available from the manufacturer, and the switches cannot be 
maintained satisfactorily.  The new switches incorporate compression 
spring operations, increase switch range from 400 amps to 600 amps, and 
use sulfurhexafloride (SF-G) as recommended by NASA safety standards.


IMPACT OF DELAY:


The explosion of a switch containing several gallons of oil presents 
inevitable risk of fire, injury, and environmental pollution.  NASA 
safety standards and criteria would remain unfulfilled.


PROJECT DESCRIPTION:


This project will refurbish existing 15,000 Volt load break switches 
located throughout the center and associated support systems.

SUMMARY PURPOSE AND SCOPE:


This project provides for the rehabilitation of the Central Air System 
to assure continued safe and reliable operation of major aeronautical 
research facilities.  The Central Air System equipment has been in 
continual use for 40 years supporting research in the 10X10 Supersonic 
Wind Tunnel, 8x6/9x15 Supersonic Wind Tunnel, the Icing Research Tunnel, 
the Propulsion System Laboratory, Propulsion Lift Facility, and various 
test cells in the Engine Research Building Complex.  The work in this 
project includes rehabilitation of exhausters and exhauster drive 
motors.


PROJECT JUSTIFICATION:


This project is required to assure safe, reliable, and continued 
operation of the Central Air System which is a basic institutional 
capability that supports: development of propulsion systems for subsonic 
and supersonic transports, hypersonic vehicles, other advanced systems 
for commercial and military applications and other various activities.  
The impellers of the exhauster system were fabricated more than 40 years 
ago.  Over time the impeller vanes have acquired numerous cracks varying 
in size from 1.5 mm to 50 mm.  The cracks can cause catastrophic failure 
of the system resulting in the possible loss of life and excessive 
downtime of the system.  This project will replace existing rotors, 
reducing delays in vital LeRC research programs caused by excessive 
maintenance time.  Repair of Exhauster Drive Motors is necessary to 
assure safe and reliable operation.  Periodic observations of these 
motors indicate that the insulation is deteriorating, which will 
eventually lead to a major failure.


IMPACT OF DELAY:


Delay of this project will significantly increase the risk of 
unscheduled and lengthy shutdowns of the Central Air System and also one 
or more of the other major research facilities at Lewis.  The current 
and planned heavily scheduled propulsion testing is dependent on a high 
degree of integrity and availability of the Central Air System.


PROJECT DESCRIPTION:


This project includes replacing deteriorated impellers in exhausters E-
41, E-43, E-44, and E-46 located in the Central Air Equipment Building 
(CAEB) (Bldg. 64).  Exhauster inlet guide vanes, bearings, seals, and 
couplings will also be replaced. Also included is the rewinding and 
repairing of the exhauster drive motors E-1 and E-43.  New grouting will 
be provided for each motor.

tunnel operations, contamination control, critical pneumatic systems, 
scientific experiments, and neutral buoyancy activities.  The existing 
compressors are 26 to 40 years old and very deteriorated.  During recent 
years, compressor downtime has resulted in a 23 percent reduction in 
rated compressor output.  Compressor downtime can commonly run into 
months due to the unavailability of parts.  Air storage vessels continue 
to be downrated or removed from service due to extensive deterioration.  
With the High Pressure Air Compressor System already operating at 
capacity, the loss of one compressor or storage vessel results in 
testing delays.  The original facilities are not suitable for 
refurbishment, so they will be deactivated after the new facility is 
fully operational.


IMPACT OF DELAY:


Delay of this project will impact all on-going programs at the Center.  
Support of test programs will become increasingly unreliable due to 
continued equipment failure and difficulty of maintenance.


PROJECT DESCRIPTION:



This project provides for the installation of two air compressors with 
associated switch gear, air dryers, filters, and valves.  The project 
also provides for the installation of two air storage vessels and 
approximately 6,000 linear feet (each) of 6-inch schedule 80 and 3-inch 
schedule 40 carbon steel pipe to tie the Wind Tunnel area to the 
existing air distribution system.

SUMMARY PURPOSE AND SCOPE:


This project provides for the restoration and modernization of the "C" 
Wing of Building 4487 to create an efficient office laboratory/computer 
complex environment.


PROJECT JUSTIFICATION:


Building 4487, totaling 278,385 square feet, was built in phases 
beginning in 1957 and has transitioned in use from a laboratory building 
to an office/laboratory/computer complex.  The facility is the CenterŐs 
primary electronics laboratory, supporting current NASA programs as well 
as research and development for future programs.  Installation of 
laboratory and computer equipment has overloaded both power 
supply/distribution and heating, ventilating, and air conditioning 
(HVAC) systems, resulting in frequent system failures.  The facility 
workplace environment is markedly substandard with inadequate and 
unreliable HVAC system, poor space allocaton/ configuration, and 
deficient supporting utility systems.  Widespread use of asbestos in 
this building further complicates its utilization.  Original 
construction of non-insulated masonry exterior walls and casement 
windows results in the building being extremely energy inefficient.  
This project will correct these problems and create useable work space 
so that complete functions can interact in close proximity to each 
other.


IMPACT OF DELAY:


Increased laboratory and computer equipment failures will occur due to 
deteriorated power distribution and HVAC overloads.  Operation and 
maintenance expenses will continue to increase to support piecemeal 
repairs.  Worker productivity and morale will continue to decrease as 
staffs are consolidated into what is already a poorly configured, 
overloaded, and low quality workspace.


PROJECT DESCRIPTION:


This project provides for complete restoration of the "C" Wing of 
Building 4487.  The building exterior will be insulated and will receive 
a new facade, including windows.  Asbestos laden interior walls will be 
removed.  Floor, wall, and ceiling surfaces will be upgraded.  The HVAC 
system, the plumbing system, the power supply and distribution system; 
and the lighting system will be replaced.  The project also provides for 
the restoration of a small sector of "A" Wing.

SUMMARY PURPOSE AND SCOPE:


This project provides for the restoration of the navigational lock to 
ensure continued reliability and maintainability of the lock supporting 
testing programs at Stennis Space Center including the Space Shuttle 
Main Engine (SSME) testing program.


PROJECT JUSTIFICATION:


Nine propellent barges supply liquid nitrogen and oxygen to the SSME 
Test Stands during SSME test operations. The navigational lock is a 
critical element in the barge transportation system. Repeated deferrals 
of major repairs have resulted in accelerated deterioration and 
increased maintenance costs.


IMPACT OF DELAY:


A delay in the implementation of this project increases the potential 
for a failure within the navigational lock system with an adverse impact 
to the SSME testing operations.


PROJECT DESCRIPTION:


This project provides for the restoration of the navigational lock. The 
work includes restoration of the cathodic protection system of the lock; 
cleaning and repainting rusted surfaces; mechanical overhaul and 
structural repair of the upper and lower canal lock gates; and repair or 
replacement of the valves, pumps, controls, and electrical wiring at the 
lock pumping station.

SUMMARY PURPOSE AND SCOPE:


The project provides for the restoration of the primary high voltage 
electrical distribution system on the Main Base at Wallops Flight 
Facility.  The modification will replace a 2.4kV and 12.5kV above ground 
distribution system with an underground system designed to satisfy 
current and future research and development requirements. 


PROJECT JUSTIFICATION:


The high voltage distribution system on Wallops Main Base is 40 years 
old and is approaching the end of its expected useful life.  It requires 
excessive repairs and maintenance to minimize failures and power outages 
to facilities.  The overhead electrical distribution system to various 
facilities is difficult and dangerous to maintain and operate due to its 
location over parking areas, streets, and buildings.  An underground 
distribution of primary electrical service to the facilities housing 
research tracking and other related support activities will be more 
reliable, safer, and easier to maintain.


IMPACT OF DELAY:


Power outages will continue to threaten damage to sensitive and high 
valued equipment.  Operations will continue to be delayed by inefficient 
short-term repairs to the electrical distribution system.


PROJECT DESCRIPTION:


This project provides for the restoration of the Wallops Flight Facility 
electrical distribution system on the Main Base.  It includes the 
removal of 4,600 circuit meters of overhead (2.4kV and 12.5kV) 
distribution system and replacement with a new 12.5kV underground 
system.  The new system will also include concrete duct banks, 
transformers, switchgear, manholes, and secondary feeder services.
