COGNIZANT INSTALLATIONS/LOCATIONS OF PROJECT:  Various Locations


COGNIZANT HEADQUARTERS OFFICE:  Office of Management Systems and Facilities


SUMMARY PURPOSE AND SCOPE:


These resources will provide for critical repairs to facilities at NASA field installations and 
Government-owned industrial plants supporting NASA activities.  Included in the request are those 
facility repair needs for FY 1996 that can be identified at the time of the submission of these 
estimates and are not in excess of $1.5 million per project.  The thrust of this program is to 
restore facilities and components thereof, including collateral equipment, to a condition 
substantially equivalent to their originally intended and designed capability.  The request 
includes the substantially equivalent replacement of utility systems and collateral equipment 
necessitated by incipient or actual breakdown.  This work also includes major preventive measures 
that are normally accomplished on a cyclic schedule. 


PROJECT JUSTIFICATION:


NASA is now experiencing block obsolescence where a substantial portion of the agencys 
facilities have been in use for over 25 to 30 years.  Repair costs for mechanical and electrical 
systems in a typical building are almost three times higher after system operations exceed 15–20 
years than they are during the initial years.  Many electrical and mechanical components reach 
the end of their serviceable or economic life at the 20 year point and should be replaced in the 
interest of long-term economy.  Continued piecemeal repair of these components is more costly in 
the long run than replacement at the end of the economic life of the original components.  
Approximately 90 percent of NASA physical plant has been in service for over 25 years.


A major thrust of this repair program is to help preserve the capabilities of the NASA physical 
plant, which has a capital investment of $5.5 billion and a current replacement value of more 
than $15 billion.  This work must be addressed and progressively accomplished.  Otherwise, risks 
are increased and future repair costs will be significantly greater.  More importantly, there 
will be increased breakdowns, interruption of critical operations, and costly unscheduled repairs 
incurred.


This program includes only facility repair work having an estimated cost not in excess of $1-
million per project.  The work is of such a nature and magnitude that it cannot be accomplished 
by routine day-to-day facility maintenance and repair activities.  Repair projects estimated to 
cost more than $1.5 million are included as separate discrete projects in the budget request.


PROJECT DESCRIPTION:


Proposed repair projects for FY 1996 totaling $35 million are described under “PROJECT COST 
ESTIMATE.  This repair program has been distilled from requests in excess of $54 million, and 
thus represents a modest request in relation to the continuing backlog of this type of work.  The 
projects that comprise this request are of the highest priority based on relative urgency and 
expected return on investment.  Deferral of this mission-essential work would adversely impact 
the availability of critical facilities and program schedules.  Projects estimated to cost not in 
excess of $250,000 have not been individually described or identified by Center.  The total 
request for this category is $410,000.


During the course of the year, it is recognized that some rearrangement of priorities may be 
necessary.  This may force a change in some of the items to be accomplished.  Any such changes, 
however, will be accomplished within total available repair resources.  The following broad 
categories of work are described further in the PROJECT COST ESTIMATE:


        a.  Utility Systems.............................................  $9,850,000


        b.  General Purpose Buildings...................................   5,800,000


        c.  Technical Buildings/Structures..............................   8,910,000


        d.  Pavements and Drainage......................................   5,720,000


        e.  Building Exteriors and Roofs................................   4,720,000





PROJECT COST ESTIMATE:


A. Ames Research Center (ARC)............................................................  $3,550,000


   1. Repair Underground Sanitary Sewer System...........................................     580,000
Approximately 1,250 meters of sewer will be repaired in this project.  Repairs will include 
placing lining material in existing pipe and spot replacements.  The system is over 40 years old 
and has been subjected to earthquakes, encroaching tree roots, and other damage.  The piping and 
joints are cracked causing waste to seep into the ground and ground water to infiltrate into 
system causing increased sewage treatment cost.  Tree roots have caused numerous blockages severe 
enough to cause waste to back up into buildings.


   2. Repair of Pressure Systems (N229A).................................................     660,000
This project will replace or repair as needed 21,000 kPa piping distribution systems and 
interstage piping associated with the compressors located in the 3.5-foot Hypersonic Wind Tunnel 
Auxiliaries Building (N-229A).  The recently completed pressure systems recertification 
inspections have revealed a major portion of the interstage piping for the compressors is of 
substandard quality.  If weld failure occurs, it would pose danger to the system, the building, 
and to human life.


   3. Repair Steam Vacuum System Lines (N234A)............................................    400,000
This project will replace the high pressure steam lines in the Steam Vacuum System (SVS) of the 
Thermal Protection Laboratory Boiler Building.  The recently completed in-house inspection of the 
high pressure steam lines in the SVS determined that all welds in the system were potentially 
defective due to substandard welding procedures.  Twenty percent of the welds were 
radiographically inspected and all possessed non-acceptable weld defects that could result in 
piping failures while in service.  If failure occurs, it would pose a danger to the system and 
human life.


   4. Repair of 80 X 120 Wind Tunnel Access Doors.........................................    480,000
This project will improve the latching mechanisms and limit switches, and will provide 
maintenance access platforms and ladders.  In order to perform maintenance or safety inspections 
on the doors, maintenance personnel currently must climb out onto the structures high above the 
ground and crawl to the latching mechanisms to service them.  This inherently unsafe practice is 
not acceptable by NASA and OSHA standards.  Failure to install ladders and platforms may result 
in injury or loss of life.


   5. Repair Water Distribution System....................................................    580,000
This project will replace various components of the Ames and Moffett Field center wide potable 
and fire water distribution systems.  The majority of piping, valves, and regulators for the 
water distribution systems are approaching 50 years of age.  This, coupled with corrosive 
subsurface conditions has degraded the components to an unreliable state.  Failure to repair the 
water distribution systems could cause damage to existing facilities, injury to personnel, and 
contamination of potable water supply.


   6. Replace Water Pumps (N234).........................................................     460,000
This project will increase the reliability of the Thermal Protection Laboratory Cooling Water 
System supporting the testing performed in N234A and N238, by replacing the high pressure cooling 
water pumps, motors, and bases.  These pumps provide critical cooling water to the high energy 
Arc Jet Electrode Assemblies, Constricted Arc Column, Nozzle Throat Section, and Power Bus 
Subsystem.  Pump failure with a corresponding drop in cooling water flow-rate could create 
catastrophic failure of equipment and danger to personnel.


   7. Repair Duct Work (N239)...........................................................      390,000
This project will repair existing duct work in the Life Sciences Research Laboratory.  Internal 
sound insulation will be removed and ducts, air handlers, and components will be cleaned.  Access 
panels will be installed for duct and heating coil maintenance.  A wall will be constructed 
around the air intake vent to eliminate excess dirt and fume ingestion.  Building N-239 lab areas 
require 100 percent outside air.  Over the years dirt and dust have accumulated in ducts and 
equipment.  The high velocity and air volume in the ducts disturbs the dust and creates 
particulate flow throughout the building.



B. Dryden Flight Research Center (DFRC).................................................   $1,320,000


   1. Repair Dryden Central Steam Plant (4886)..........................................      240,000
This project replaces the existing system with two new 112 kW natural gas fired steam boilers, 
de–aerator and condensate recovery system, associated piping, computerized water treatment 
system, and an air pollution control system. Building 4886 is the main source of heat for 
Building 4800, Dryden’s largest building, and two of Drydens major hangars, Buildings 4801 and 
4802. This system was constructed in 1954 and all components have exceeded their useful life 
expectancy. The steam distribution system, including air handlers and distribution piping, is 
already in place, but the boiler must be replaced in order to make the system efficient.


   2. Repair Dryden 35,000 Volt Circuit................................................       450,000
This project will replace an unreliable power transmission system between Substation 16 and 
Building 4840 with a new six-way duct bank with individual cables feeding each transformer from 
Substation 16. Manhole E-25A will be removed and replaced due to violation of National Electrical 
Codes. If existing 35 kV feeder cables were to fail, the failure or explosion would damage the 
duct, making it impossible to remove the damaged cable or to pull a new cable in the damaged 
duct. The existing transformers have no separate over-current protection within the manhole, so 
if one transformer fails, they all fail.


   3. Repair Roads, Paving, and Main Parking Area......................................       630,000
This project provides for the repair of roads, paving, and parking areas including some flight 
line areas.  The work includes the repair of cracked pavement and potholes, resurfacing 
approximately 24,000 square meters of asphalt pavement, and the realignment of Forbes Avenue 
roadway.  This project is needed to bring the existing roads, paving, and parking areas back into 
maintainable condition. Continued neglect of flight line areas will cause foreign object damage 
(FOD) to aircraft engines, tires, and landing gear systems, and may cause damage to aircraft 
ground equipment (making some areas unusable for aircraft). Forbes Avenue roadway safety is 
compromised due to drainage problems and poor sight distances.


C. Goddard Space Flight Center (GSFC)..................................................   $2,800,000


   1. Replace Roofs, Buildings 28 and 17...............................................      700,000
This project provides for the repair of portions of roofs on Buildings 28 and 17.  The work 
involves the replacement of 4,500 square meters on the Technical Processing Facility (28) and 
1,800 square meters on Administrative Support Building (17).  The work includes removal of 
existing roof assemblies down to the structure and their replacement with new insulation and 
modified membrane roof system.  These roofs have a history of leaks and drainage problems.  The 
new roofing system will remedy the defects and reduce maintenance costs. 


   2. Repair Exterior of Research Projects Lab (2).....................................      900,000
This project will provide for the repair of building exterior components on the north side of the 
Research Projects Laboratory (Building 2).  The project includes replacement of existing exterior 
metal panel systems and windows as well as masonry repairs.  In addition, this project will 
replace induction unit component parts, including modifications to the associated secondary water 
systems and air handling units.  Asbestos will be removed as required.  This building shows 
numerous signs of water damage due to deterioration of the exterior wall system.  The proposed 
work will restore facility integrity and minimize potential loss of government property due to 
water damage.


   3. Repair Air Handling Units and Controls, Buildings 16 and 26......................      650,000
This project provides for the replacement of air handling unit components and related piping and 
controls in Logistic and Supply Facility, Building 16 and Space Science and Data Center, Building 
26.  Asbestos will be removed as required.  The existing control valves for the induction units 
need to be replaced because they frequently malfunction after becoming clogged with scale.  Other 
components which have deteriorated and need to be replaced include the induction unit drain pans, 
piping, and dielectric couplings.  Heat exchangers need to be provided in Building 26 to prevent 
contamination of the secondary water system by the primary system.  The air handling units in 
these buildings have exceeded their design life and are inadequate for their present usage.


   4. Repair Electrical Systems, Various Buildings.....................................     550,000
This project provides for the replacement of motor control centers in Building 5.  In addition, 
replacement of individual wall mounted motor starters in Buildings 16, 17, 18, 19, 20, and 25 
with centralized motor control centers is included.  This project is required to replace 
electrical equipment which is in poor condition due to age and excessive usage.  The equipment is 
obsolete and replacement parts are often not available.  Replacement of this equipment will 
improve maintainability and reliability.


D. Jet Propulsion Laboratory (JPL)....................................................   $2,600,000


   1. Repair Curtain Wall, Space Flight Support Facility (264)........................      900,000
This project will repair approximately 2,200 square meters of existing curtain wall on the north 
and east facades of this eight story building.  A new curtain wall system will be attached to the 
exterior of the existing system utilizing the existing vertical mullions for structural support. 
The new system will include new glazing and gutters.  The building has a severe leakage problem 
and glass plates have fallen out.  Hazardous conditions have resulted from water passing through 
the curtain wall and soaking the carpet, electrical cords, and equipment.


   2. Refurbish Corridors, Control Systems Laboratory (198)...........................      650,000
This project will replace approximately 730 square meters of deteriorated, outdated finish 
details.  The work includes replacement of ceiling panels, carpeting, and painting.   New duct 
work will be provided for the return air plenum. All doors will be replaced with 20 minute fire 
rated doors.  The building has been converted from laboratory space to offices with a significant 
increase in building population.  Renovation of the heating, ventilating, and air conditioning 
system is required to eliminate the corridor as a return plenum.  Return air registers at the end 
of the corridors will be removed and openings closed.  The corridors are being renovated to 
provide fire rated ceilings and doors to conform with life-safety building codes.


   3. Repair Exterior, Physical Science Laboratory (183)..............................     450,000
This project provides for the repair of approximately 2,900 square meters of the exterior surface 
of Building 183.  The project will remove existing coatings, and repair and reseal plaster 
panels.  Included is caulking and flashing around doors, windows, and other openings.  The east 
and west masonry walls will be cleaned, repainted, and waterproofed.  All window wall glazing in 
the lower lobby area will be removed and replaced.  The existing plaster walls have deteriorated, 
cracked, and peeled.  Mortar joints in the masonry walls are pitted.  Caulking and flashing 
around windows and other openings are dried and cracked.  These conditions allow water to 
penetrate the building.


   4. Repair Paving, Upper West Parking Lot...........................................     600,000
The project will remove and replace approximately 12,000 square meters of asphalt paving on the 
upper west parking lot including a portion of Explorer Road and parking areas adjacent to it from 
Gyro Road on the west to the intersection of Pioneer Road on the east.  The pavement will be 
removed and the area will be regraded.  A new 150mm aggregate base and 75 mm asphalt paving will 
be placed.  Included will be a new concrete surface drainage system.  The pavement is 30 years 
old and is severely deteriorated.  Slurry coating is not justifiable as the sub-base is unstable 
and would not hold up under constant traffic.  In addition, approximately 50 more parking spaces 
will be created by restoring the lot with 2.5 meter stalls.


E. Johnson Space Center (JSC)...........................................................2,750,000


   1. Repair Access Road, White Sands Test Facility....................................   900,000
This project provides for repair of the main access road to the White Sands Test Facility (WSTF).  
The work consists of repairing the approximately 9.7 kilometer long by 7.3 meters wide road.  The 
repair will include crack sealing of approximately 76,100 square meters of existing pavement and 
laying a 51 millimeter thick hot mix overlay.  In addition, the shoulders will be raised to match 
the new surface, settling basins will be dug at locations on the upstream side, and the 
downstream shoulders will be engineered to prevent undercutting.  The access road has not had a 
major repair since it was constructed in 1963.  Normal wear and tear over the last 31 years, plus 
additional heavy construction traffic in the last 15 years, have made the replacement of the 
surface necessary.  Without major repair and a new surface, continued degradation of the road 
will result in major damage to the road base necessitating a considerably more expensive repair.


   2. Repair Aircraft Operations Facilities, Various Buildings Ellington Field........   500,000
This project provides for selective repair and/or replacement of architectural, structural, 
mechanical, and electrical systems in various buildings at Ellington Field.  The work includes 
replacement of interior and exterior building and roofing components, access modifications, air 
conditioning and condensing units, electrical panels, transformers, lightning protection, wiring, 
and lights.  The facilities are over 40 years old and many of the buildings’ components and 
systems have exceeded their life  expectancy.  These repairs will bring the buildings up to 
current life safety standards.


   3. Repair Avionics Systems Laboratory Mechanical Systems (16)......................  900,000
This project provides for repair of heating, ventilating, and air conditioning (HVAC) equipment 
in the Avionics Systems Laboratory.  Also included is the installation of an automatic sprinkler 
system.  Work includes the repair/replacement of air-handler casing and structures, valves, and 
fan scroll assemblies.  The existing outdated HVAC control systems will be replaced with energy 
efficient controls.  This project will replace primary HVAC equipment that is over 30 years old 
and beyond its useful life.  The new HVAC system will provide efficient, reliable, and economical 
service to the facility.


   4. Repair Roads, Various Locations................................................   450,000
This project provides for major repairs of roads at the center.  The work includes five district 
locations along First, Second, Fourth, and Fifth Streets.  The work will include the replacement 
of base material, replacement of worn surface material, and striping/marking for identification 
and traffic control.  The center’s roads are at the end of their service life and have received 
only minimal surface maintenance since construction in 1962.


F. Kennedy Space Center (KSC)........................................................$3,750,000


    1. Replace Roof, Vertical Processing Facility....................................   480,000
This project replaces approximately 2,200 squares meters of deteriorated built-up roofing on the 
Vertical Processing Facility.  The roof has failed to the extent that maintenance and repair 
actions can no longer provide watertight integrity.  Work includes removal and replacement of 
roofing, insulation, gutters, downspouts, and lightning protection.


    2. Repair Wharf Slip at Hangar AF...............................................    800,000
This project repairs approximately 200 meters of failing seawall at the Hangar AF Wharf Slip.  
The seawall has had recent interim repairs in an attempt to slow structural degradation until 
this permanent repair can be accomplished.  Sheet piling will be sealed, backfill replaced, with 
adjacent concrete slabs stabilized and/or replaced, as appropriate.


    3. Replace Utility Annex Pumps and Controls.....................................    700,000
This project replaces three deteriorated firex pumps for which spare parts are no longer 
available.  The project will also provide for a new recirculation/test line at the utility annex.  
Internal inspections have revealed severe deterioration and erosion.


    4. Remove/Install Bridge Expansion Joints, Banana and Indian River Bridges......    600,000
This project replaces approximately 1,500 meters of bridge deck expansion joints on the Banana 
and Indian River bridges.  Deterioration of existing joints is jeopardizing the structural 
integrity of the two bridges.


    5. Repair Roads and Paved Areas, Various Locations..............................    600,000
This project repairs approximately 60,000 square meters of paving throughout the Kennedy Space 
Center.  Surface courses will be sealed or replaced as appropriate, base courses repaired or 
replaced as necessary, and restriping accomplished.  Surface water runoff control will also be 
provided as required by environmental regulations.


    6. Repair Flame Deflection Systems..............................................    570,000
This project repairs deteriorated flame deflectors which are part of Space Shuttle Launch Complex 
Pads A and B.  Launch vibrations have caused large sections to separate during vehicle lift off.  
Flame retardant concrete and steel coatings will be replaced, as well as corroded structural 
steel components.  The project will also evaluate alternate positions for the deflector units in 
an effort to reduce the corrosive effect of launch activity.


G. Langley Research Center (LaRC).................................................. $4,270,000


    1. Repairs to Central Heating and Steam Generating Facility (1215).............    900,000
This project provides for the replacement of the existing control systems for the boilers, air 
compressors, and the central alarm system at the Central Heating and Steam Generation Facility 
which serves LaRC’s West Area.  The new central control station will be environmentally enclosed 
and controlled.  The project will include an approximately 93 square meter addition to the 
facility to offset the space required by the replacement control station.  The existing control 
panel is over 45 years old and requires replacement to assure continued safe operation, reduce 
maintenance, and increase reliability and efficiency.


    2. Replace Liquid Rheostat Serving Unitary Wind Tunnel (1251).................     920,000
This project provides for the replacement of the existing liquid rheostat which provides control 
of the electrical power to a pair of synchronous main drive motors for the Unitary Wind Tunnel.  
The work to be accomplished includes the removal of the existing liquid rheostat, modifications 
to piping and wiring to provide for the installation of the new equipment, and the installation 
of a new liquid rheostat and associated mechanical and control components.  The liquid rheostat 
was installed in the mid 1950’s and replacement parts are difficult to locate.  Failure to 
replace the liquid rheostat as scheduled will result in increased losses of tunnel operating time 
and possible shutdown of the facility if a catastrophic failure occurs.


    3. Repairs to High Pressure Systems, Various Facilities......................     700,000
This project provides for the repairs to the high pressure systems at various facilities.  The 
work to be done under this project includes the replacement of defective piping, valves, and 
fittings; radiographic inspection of welds; and repair of defective welds.  The systems to be 
repaired include piping systems and pressure vessels at the West Area Steam Generating Facility 
(1215), the Steam Distribution System, the Jet Exit Test Facility, the East Area Compressor 
Station (646), and the Unitary Wind Tunnel (1251).  These systems are being analyzed and spot 
inspected under Langley Research Center’s ongoing Recertification Program.  Completion of this 
project is essential to ensure the safe and efficient operation of these facilities.


    4. Replacement of Substations, Various Locations............................     900,000
This project provides for the replacement of 208 volt substation "LF-100," 480 volt substation 
“PF-100,” and 480 volt Substation Number 5.  The project will include replacement of the air 
switch, secondary switchgear, and drawout circuit breakers for each of the substations.  The 
switchgear, breakers, and primary air switch for each substation are obsolete and replacement 
parts are difficult to obtain.  Substations "LF-100" and "PF-100" are over 40 years old.  The 
replacement of these substations will reduce maintenance, reduce downtime, and improve system 
reliability and safety for the five facilities served.


    5. Replace Roof, Engineering Building (1209)...............................      850,000
This project provides for replacement of approximately 4,830 square meters of existing built-up 
roofing on the Engineering Building (1209). The new roof will consist of tapered rigid roof 
insulation to provide a 2.08 centimeter per meter slope covered by a 4-ply built-up roof system.  
The new roof will be complete with roof drains and associated plumbing, flashing, fascia, pitch 
pockets, cant strips, gravel stops, and new expansion joints as required.  Water which has become 
trapped between layers of the 17 year old built-up roofing causes the roof to expand due to 
temperature changes, causing further damage.  The roof replacement is necessary to ensure the 
integrity of this facility and to prevent damage to critical engineering and planning files,
