About this file
This is a cost estimate document for proposed generator additions at two Illinois Department of Transportation (IDOT) District 3 maintenance yards, prepared as of May 1, 2025. The project encompasses electrical infrastructure upgrades at the Ladd Maintenance Yard and Sycamore Maintenance Yard, with the primary objective of installing standby generator systems and associated electrical distribution components. The Ladd project includes a 96kW/120kVA generator set with a 400A automatic transfer switch, service entrance upgrades, multiple panel installations (PP-1, D0222 MDP, D0223, and Tire Shed panels), and associated feeder conductors and ground fields. The Sycamore project features a 60kW/75kVA generator set with a 225A automatic transfer switch and four electrical panels (A, B, C, and D), along with concrete generator pads, gas service modifications, and comprehensive electrical distribution infrastructure. Both projects include miscellaneous items such as overcurrent studies, legend plates, and labels.
The document provides a detailed line-item breakdown of materials and quantities required for each location but does not specify unit pricing, total project costs, funding sources, or contract award information. No response dates, bid deadlines, site visit requirements, or bidders' conferences are identified in this preliminary cost estimate. The document serves as a planning tool for estimating the scope and scale of generator addition work at these two IDOT facilities, with quantities listed in units such as lump sum (LS), linear feet (LF), square feet (SF), and each (EA).
