C -- SOURCES SOUGHT FOR A/E DESIGN SERVICES FOR MOD OF 138KV AND 34.5K POWER SYSTEM AT LERC POC Angel Pagan, Contracting Officer, (216) 433-2791, MS 500-312 Internet E-Mail apagan@lerc.nasa.gov Louis Bernhardt, Project Manager, (216) 433-5451, MS 501-10. Request for A/E Design Services for the Rehabilitation and Modification of the LeRC 138KV and 34.5KV Power System. The design will produce three distinct, stand-alone, construction bid packages to be used for three distinct phases of construction. Phase One will primarily involve the construction of a new 138KV substation with new duct banks and ties made to existing substations. Phase Two will primarily involve the replacement of 34.5KV insulators, breakers, disconnect switches, and some transformers located at various substations throughout the Center. Also included in Phase Two is the rehabilitation of Variable Frequency Drive No. 1 at Bldg. 64. Phase Three will primarily involve the reconfiguration of power feeds to and from various substations; the elimination of some overhead supply lines; the rehabilitation of Variable Frequency Drive No. 2 at Bldg. 64; and installation of new underground ductbanks. Modifications to the Protective Relaying System will also be made during each phase of the rehabilitation. The major disciplines required are electrical, structural, and civil and within these disciplines specialized experience is required in the 138KV and 34.5KV Power Field. The Protective Relaying System Modifications will also require specialized experience in the application of Fiber Optic Technology to protective relaying/power system monitoring. Work will include preparation of engineering studies, final design, field investigation, and related services under a fixed price contract.
