SUMMARY PURPOSE AND SCOPE:
The Launch Complex 39 Pad A Payload Changeout Room (PCR) was originally
designed and built to provide a controlled environment for pre-flight
services of space shuttle hardware. This project replaces damaged
structures that now allow contaminants to enter the PCRís
controlled space. It also enhances the efficient and effective
operation and maintenance of the PCR space and supporting utilities.
The PCR is required for Kennedy Space Center to perform its assigned
Agency roles and missions.
PROJECT JUSTIFICATION:
Contamination levels within the PCR have increased significantly.
These contaminants enter the PCR via the damaged exterior walls
and deteriorated access doors, which can no longer maintain necessary
pressurization levels. Friable insulation associated with mechanical
components also contributes to the contamination. This project
will prevent the payload processing environment from exceeding
acceptable limits for contamination and pressurization capability
and becoming a launch constraint.
IMPACT OF DELAY:
Failure to provide timely repair of the PCR structure and supporting
mechanical systems will allow contamination levels to exceed acceptable
limits. This will hinder space shuttle launch preparation and
potentially cause launch delays. Also, operation and maintenance
costs associated with keeping the deteriorated structure and mechanical
components operating will continue to increase.
PROJECT DESCRIPTION:
This project replaces damaged PCR wall panels, illuminates the
access area within the PCR plenum, replaces the ceiling grid assembly,
and replaces or eliminates various leaking access doors. The high
efficiency particular air (HEPA) filter housing will be reconfigured
to allow safer accessibility.

SUMMARY PURPOSE AND SCOPE:
This project restores the structural concrete of the launch pad
surfaces to prevent the ingress of water which accelerates deterioration
of subbase materials and imbedded reinforcing steel. Pad A is
required for Kennedy Space Center to perform its assigned Agency
roles and missions.
PROJECT JUSTIFICATION:
Pad Aís concrete surface, slopes, and catacomb areas are
over 30 years old, and deteriorated with cracks, spalls, and broken
sections that are unsafe for launch operations. The cracks in
the pad surface permit launch and rain water to leak into and
weaken the underlying compacted fill. Launch vibration and hydrostatic
pressure on the undermined slopes cause the concrete panels to
crack further and break into pieces. Cracks in the pad surfaces
allow acidic launch water to attack the pad rebar, which erodes
and results in spall failures of the catacomb ceiling and a structural
weakening of the launch pad. The crawlerway grid path also has
cracks in the substructure, which allows water to undermine the
slopes and also attack the catacomb rebar and concrete.
IMPACT OF DELAY:
Failure to provide timely repair of the launch pad concrete surfaces
will allow the rate of water infiltration and subsequent structural
weakening to accelerate, rapidly increasing the ultimate repair
cost. Also, the shuttle manifest allows a unique five-month window
in January 1998 to implement this project. The next available
window will be in the year 2001.
PROJECT DESCRIPTION:
This project repairs cracks in the launch pad concrete surfaces
and replaces or repairs fractured and broken sections of concrete.
The cracked areas of the pad slopes will be sealed and the broken
and raised or ìbulgedî portions will be removed.
The underlying fill will be replaced and recompacted. The subbase
under the crawlerway slabs will also be repaired. Cracks and joints
on the pad surface will be sealed. The cracks in the concrete
ceiling structure of the catacombs will be repaired.

PROJECT TITLE: Rehabilitation of 480V Electrical Distribution
System, External Tank Manufacturing Building
INSTALLATION: Michoud Assembly Facility
FY 1998 ESTIMATE: $2,800,000
LOCATION OF PROJECT: New Orleans, Orleans Parish, Louisiana
COGNIZANT HEADQUARTERS OFFICE: Office of Space Flight
FY 1997 AND PRIOR YEARS FUNDING: The following prior years
funding is related to this project:
| Planning and Design | Construction | Total | |
| Specific Construction Funding | $382,000 | $ 2,500,000 | $ 2,882,000 |
| Capitalized Investment | --- | 54,444,830 | 54,444,830 |
| Total | $382,000 | $56,944,830 | $57,326,830 |
SUMMARY PURPOSE AND SCOPE:
This project rehabilitates and modifies the 480V electrical distribution
system which supports critical External Tank (ET) manufacturing
operations in the Mechanical Sub-Assembly, Intertank, and Dome
Assembly areas of the ET Manufacturing Building (103). This project
specifically replaces the electrical distribution system associated
with substations 3, 4, and 5. It is required to restore quality
and reliability to the electrical power system and avoid costly
piecemeal repairs. Building 103 is required for the Michoud Assembly
Facility to perform its assigned Agency roles and missions.
PROJECT JUSTIFICATION:
The 480V electrical distribution system in Building 103 was originally
installed in the 1940ís. Exposed distribution feeders resulting
from cracked insulation and "spot" overloads combine
to create potential production shutdowns. Existing bus ducts are
inaccessible for maintenance. Feeder taps to fan houses lack overcurrent
protection. Main distribution and sub-distribution panels and
associated breakers are obsolete. Existing grounding does not
meet the National Electric Code (NEC) nor current design standards.
An in-house long range electrical plan and a subsequent A/E study
recommend upgrade of the 480V power distribution system. This
project is needed to provide a safe and reliable 480V electrical
distribution system from substations 3, 4, and 5 to the Mechanical
Sub-Assembly, Intertank, and Dome Assembly areas of Building 103.
It continues the systematic rehabilitation of older high-voltage
systems in critical production areas.
IMPACT OF DELAY:
Failure to rehabilitate exposed feeders, hot spots, and improper
grounding may likely result in production shutdowns in the Mechanical
Sub-Assembly, Intertank, and Dome Assembly areas of the External
Tank manufacturing operations.
PROJECT DESCRIPTION:
This project installs new main distribution and sub-distribution
power panels and new transformers. New electrical distribution
feeders will be routed in cable trays for ease of maintenance.
Electrical distribution circuits will be designed to eliminate
the need for bus ducts. The new distribution system will be tied
into substation switch gear and the old distribution system will
be demolished.

FUTURE ESTIMATED CONSTRUCTION FUNDING REQUIRED TO COMPLETE
THIS PROJECT: None. However, future CoF funding in the amount
of $3,800,000 will be required in FY 1999-2000 to rehabilitate
the 480V electrical distribution system in the remaining areas
of Building 103.
