On June 5, 2016, the 42-inch concrete water main installed in 1982 at the Interstate Highway (I.H.) 30/Beach Street intersection broke in at least one section. Due to the high pressure of the water in the pipe, the resulting damage from the break was extensive. The water main was quickly valved off and isolated by Water Field Operations crews thereby preventing widespread damage, operational problems and impacts to I.H.30 traffic flow.
Large Water Main Breaks are a threat to the health and safety of the City of Fort Worth. Chapter 2, Article I, Section 2-9 of the City's Code of Ordinances and Section 252.022 of the Local Government Code exempts from normal bidding requirements expenditures that are necessary to preserve or protect public health or safety of the municipality's residents and procurements necessary because of unforeseen damage to public machinery, equipment, or property.
The replacement line was designed by in-house Engineering Staff. Work included removal of the damaged section of 42-inch concrete pipe from the 72-inch tunnel crossing the interstate, installation of new higher rated steel pipe within the tunnel, modifications to an existing valve vault, and repairs to TXDOT's concrete riprap near the Beach and IH 30 bridge.
The attached City Manager memo dated June 6, 2016 approved the emergency work up to $500,000.00. The total construction cost was $531,876.00, which is fair and reasonable for the work performed.
This project was located in COUNCIL DISTRICT 8, Mapsco 78A.. This contract legally does not require City Council approval.
