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 the installation of backup generator systems at the Ladd Maintenance Yard and the Sycamore Maintenance Yard. At Ladd, the scope includes a 96kW/120kVA standby generator with a 400A automatic transfer switch, service entrance modifications, and electrical distribution panel upgrades across multiple panels including PP-1, D0222 MDP, D0222 Bay #2, D0223 5-Bay, and a Tire Shed panel. At Sycamore, the project specifies a 60kW/75kVA standby generator with a 225A automatic transfer switch and electrical distribution modifications across panels A, B, C, and D. Both locations require concrete generator pads with aggregate bases, feeder conductors and conduit installations, ground field work, existing service connection modifications, and miscellaneous items such as overcurrent studies and legend plate installation.
The document provides detailed line-item quantities and unit types for all materials and labor components required for both generator installations. Specific electrical components include main disconnect switches, breakers of varying amperage ratings, panel configurations ranging from 12 to 42 circuits, and underground pullboxes. The cost estimate format indicates pricing will be determined by responsive bidders, with the project intended to provide comprehensive backup power capabilities for both maintenance yard facilities. No pricing, funding source, contract term, or award information is provided in this cost estimate document.
