This project is part of Nicor’s Crawford Replacement program, a seven-phase effort replacing approximately 13 miles of 20-inch sandwich main. d’Escoto provided construction inspection services for the first phase, Crawford Phase 7, responsible for inspecting construction, installation, and commissioning activities performed by Nicor’s contractor.
Phase 7 involved removing the existing 10-inch and 20-inch steel sandwich transmission and installing one 24-inch steel distribution line spanning 2.2 miles from Station 147 to Governors Highway/Crawford Avenue. The existing 20-inch line, located on a seven-foot easement in ComEd’s right-of-way, was removed in accordance with ComEd requirements.
