Included in this request are those facility rehabilitation and modification needs for FY 1996 that have been fully identified at the time of the submission of these estimates and are estimated not to exceed $1.5 million per project. The purpose of this program may include some restoration of current functional capability but also includes enhancement of the condition of a facility so that it can more effectively accomplish its designated purpose or increase its functional capability.

PROJECT JUSTIFICATION: The NASA physical plant has a capital investment of $5.5 billion and has a current replacement value of more than $15 billion. A continuing program of rehabilitation and modification of these facilities is required to accomplish the following: a. Protect the capital investment in these facilities by minimizing the cumulative effects of wear and deterioration. b. Ensure that these facilities are continuously available and that they operate at peak efficiency. c. Improve the capabilities and usefulness of these facilities and thereby mitigate the effects of obsolescence. d. Provide a better and safer environment for all personnel. This program includes only facility rehabilitation and modification work having an estimated cost not in excess of $1.5 million. The work is of such a nature and magnitude that it cannot be accomplished by routine day-to-day facility maintenance or by related routine facility work efforts. PROJECT DESCRIPTION: Proposed rehabilitation and modification projects for FY 1996 totaling $35 million are described under PROJECT COST ESTIMATE. The total program of $35 million has been distilled from requests of $58 million and represents only a modest request in relation to the backlog of this type of work. Based on relative urgency and expected return on investment, the projects that comprise this request are the highest priority requirements. Deferral of this mission-essential work would adversely affect the availability of critical facilities, program schedules, and energy-conservation objectives. Projects estimated to cost not in excess of $250,000 have not been described individually or identified by center. The total request for this category is $480,000. During the course of the year, some rearrangement of priorities may be necessary. This may force a change in some of the items to be accomplished. Any such change will be accomplished within available resources. The following broad categories of work are described further in the PROJECT COST ESTIMATE: a. Utility Systems $5,715,000 b. Fire Detection/Protection Systems 4,505,000 c. General Purpose Buildings 7,655,000 d. Technical Buildings/Structures 17,125,000 PROJECT COST ESTIMATE: A.

Modify Utility Control System, Various Locations...................600,000 This project provides for modifications to the Utility Control System (UCS). The work includes replacement of the pneumatic controls and refurbishment of the air handling units for buildings 1000, 2040, and 3110. The existing UCS and HVAC systems are more than 20 years old and many parts are no longer available for the system. This project will provide for an efficient, reliable, and maintainable energy management system. L. Wallops Flight Facility (WFF).......................................$890,000 1. Rehabilitation of Aircraft Hangar (N-159)......................... 390,000 This project provides for the modification of the exterior building siding and roof top structures of this aircraft hanger. The work includes the removal of existing protected metal siding and windows; the installation of new protected steel siding, secondary support steel framing, batt insulation, metal liner panel, flashing and trim, guttering, downspouts, and splashblocks. The existing metal siding on this 35 year old hangar has outlived its life expectancy. It is damaged in places and the protective coating is cracked and peeling off. The windows in the hangar area leak and serve no useful purpose. The new metal panel system will provide a strong protective covering for the hangar and upper mechanical rooms, insulation to eliminate heat loss, and a more pleasing appearance to such a sizable structure. 2. Modification of Rocket Assembly Building Z-41..................... 500,000 This modification consists of the removal of steel, repair of the roof, and the installation of fire protection and grounding system; the installation of two 9,000 kilogram bridge cranes in the high bay area; the upgrade of overhead lighting and electrical power panels; the replacement of overhead and personnel doors; the painting of interior/exterior finishes; the rehabilitation of the restroom; and associated work. Building Z-41 is a high bay vertical assembly building strategically located to provide support to the launch facilities on Wallops Island. The building is 25 years old and is in need of rehabilitation due to age, deterioration, and exposure to the Island environment. M. Various Locations.....................................................$2,710,000 1. Rehabilitate and Modify Feedcone for 70-Meter Antenna, Goldstone, California..................................................710,000 This project will provide for a new Feedcone shell to house microwave equipment, transmitter, waveguide switches, and maser. A Dichroic mirror and retraction mechanism will be fabricated and tested. This project is required to expand the capability of the 70-meter antenna to provide both X-band uplink and downlink support to flight projects. 2. Modify Power Distribution System, Goldstone, California................600,000 The project will convert the existing 2400 V radial distribution system to a loop system. The loop system will be fed from two existing 2400 V breakers so that if one of the breakers fails or is out for maintenance, the other breaker is capable of serving the connected load without any interruption. The project includes the installation of additional 2400 V cables, ducts and trenches to complete the loop system, a new substation at DSS-15 antenna, and the modification of the power plant programmable controller to adapt it to the new configuration. This will improve maintainability, redundancy, and will allow isolation and testing of the 20 year old system. 3. Modify 34-Meter Antenna (DSS-28), Goldstone, California................500,000 This project will implement site and structural changes to the antenna facility which include fencing around the antenna apron, seismic bracing for electronic equipment, and cable trays. Also, electrical modifications will be made to the pedestal, a fire detection and a safety surveillance system will be installed, and a prefabricated metal building for a motor generator set will be constructed. Redundant air conditioning will be installed at DSS-27 and DSS-28. Operational requirements for DSS-28 require these modifications to meet safety requirements and back-up cooling capacity for critical electronic equipment. 4. Modification to Launch Area #4, Poker Flats Research Range............900,000 This project provides for the modification to Launch Area #4 located at Poker Flats, Alaska. It includes sitework; elevation of rails on a concrete base; installation of a insulated mobile shelter with rollup doors; a 16.2 square meters terminal building; and the installation of power and lighting.
