Generator set cooling and exhaust. <br /> 5. Construction cost estimating assistance. <br /> G. Electrical Engineering: <br /> 1. Generator Plant: A complete electrical energy facility will be designed with <br /> generators and switchgear to meet the following objectives. The generators will <br /> be sized to support current site demand loads with N+1 redundancy plus addition <br /> of a future generator, and capable of independent operation in the event utility <br /> power is unavailable for extended periods. The main switchgear will provide <br /> utility connection, paralleling control of installed and future permanent <br /> generators, connection and control of a temporary generator, and distribution to <br /> site transformers. The switchgear design will be modular and maintainable <br /> without site shutdown or exposure to excessive arc flash risk. The existing <br /> 480volt generators and their paralleling equipment will be removed after the new <br /> generator plant is in service. The existing utility recloser and fixed capacitors will <br /> be removed and the point of common operation will be relocated to the site <br /> perimeter. The existing SKM model will be updated with the new electrical <br /> distribution system included in the model. Arc flash calculations will be included <br /> for the new equipment. Labeling instructions will be provided. <br /> Site Distribution: A new underground site distribution system will be designed to <br /> provide power to the existing transformers. Transformers will be replaced and <br /> resized appropriate to demand loads where existing units are approaching end of <br /> service life. The distribution system will be designed for maintainability with <br /> limited impact to site operations. Redundancy will be a modular design to <br /> support installation is phases. <br /> Included in the work is an upgrade to following Motor Control Centers; <br /> MCC HFB/HFBG, replace both MCCs with single panelboard with discrete <br /> starters as required. <br /> MCC HFWPS/HFWPSG, replace both MCCs with single MCC or <br /> panelboard. Finish Water Pump#3 (250hp)starter will be replaced with VFD. <br /> MCC HW/HWGA, replace both MCCs with single unit. Two soft start and two <br /> line starters will be provided. Existing plug-based pump selection cabinet will be <br /> removed. <br /> The existing single phase transformers and 120/240volt panels will be replaced <br /> with 208Y/120volt equipment. <br /> 2. Lighting: Building Interior and exterior lighting design. The lighting design will be <br /> based upon requirements recommended by the Illuminating Engineering Society <br />
