Nicor’s Crawford line consisted of approximately 13 miles of 20-inch sandwich main, scoped for replacement in seven phases. d’Escoto provided various construction inspection services for the Crawford Phase 7 project – the first phase of the Crawford Replacement program.
During this phase, existing 10 and 20-inch steel sandwich transmission lines were removed and replaced with one 24-inch steel distribution line (2.2 miles) from Station 147 to Governors Highway/Crawford Avenue. The existing 20-inch line was on a seven-foot easement in ComEd’s right-of-way and removed per ComEd requirements, and the existing 10-inch line removed with the new 24-inch line installed in its place.
d’Escoto inspected the construction, installation, and commissioning activities performed by Nicor’s construction contractor during Phase 7 of Nicor’s Crawford distribution pipeline replacement. d’Escoto’s experienced team of qualified inspectors included:
