Base Bid A infrastructure begins at splice vaults #5A and #5B and ends at the riser structure 7-1737-114, approximately 200 feet south of Lake Underhill Road in an existing Orlando Utilities Commission overhead right of way. The furnishing and installation of splice vaults #5A and #5B are part of this scope. The new cable system shall consist of cross-linked polyethylene cables pulled into a concrete encased ductbank system, primarily installed via open cut trenching techniques. There are locations along the proposed alignment, however, where trenchless crossings exist. Below grade vaults will be positioned along the route accordingly, for cable pulling and splicing. The system has a required ampacity of 2000 A (796 MVA). From splice vaults #5A and #5B to riser structure 7-1737-114, the transmission line is approximately 24,659 feet (4.67 miles). The Contractor is to provide miscellaneous materials and services to complete the installations as specified herein and in accordance with the Orlando Utilities Commission contract documents. The base period of time for performance of the work from mobilization to final completion is fifteen months.
