Electrical Improvements - Substations 7A, 8A, 9A, 10A

The scope of work includes, but is notlimited to, furnishing all materials, labor, and equipment necessary for new electrical substation building for Substations 7A, 8A, 9A and 10A. The substations provide power for the processes at the Oxygen Generation Plant 2 Building. The electrical improvements consist of removing the existing substation transformers within the existing building and installing new transformers and electrical gear within a new Substation Building. Demolition will include the removal and disposal of the existing substation transformers and equipment associated with existing substations 7A, 8A, 9A, 10A and the existing motor starter cubicle for Compressor No. 3. In addition, the existing 1,500 HP motor will be removed and turned over to the owner and replaced with a larger owner furnished motor. General site civil work will include all grading, paving, drainage, utilities and pavement restoration. A driveway will be provided along with two on-site parking spaces. Utilities to be provided includes a water service line to be provided to the new building for cooling tower operation. The walls of the new building will consist of concrete masonry unit blocks with concrete cast-in-place columns supporting the roof loads. The roof will consist of pre-cast concrete joists connected to the concrete columns. The roofing will consist of SBS modified bituminous membrane. The columns and floor slabs will carry the loads to grade beams and pile caps, which then transmit the loads to auger cast-in-place (ACIP) concrete piles, which form part of the building`s foundation system. The new building will be designed to comply with sea level rise and storm surge design criteria for the CDWWTP which require all critical facilities to be placed at or above a finished floor elevation(FFE) of 20.9 NGVD. The Small Business Enterprise - Construction goal is 13.01% and the Small Business Enterprise - Goods goal is 3.02% which is based on the construction estimate plus the 10% Contingency Allowance.
