Report
Summary
The purpose of this project is to repair the 7th Street/Salt River bridge, ST85110177. This amendment is necessary because on Sunday, Feb. 28, 2021, a 10-inch high pressure gas line failed and caught fire under the north abutment of the 7th Street/Salt River Bridge. Critical damage occurred to the north end of the structure, which includes the northern two spans of the bridge along with the northernmost pier and abutment. These sections of the bridge will be removed and rebuilt. Anticipated closure of the bridge will be approximately six months. The City is moving expeditiously to rebuild the bridge and reopen 7th Street.
Due to the urgent and specialized nature of this project, the City engaged Hunter Contracting Co. under an existing Job Order Contract (JOC). The use of a JOC construction services master agreement allows the City to address the timeline requirements and specialized aspects of the project. City Council originally authorized this master agreement for a fee not-to-exceed $15 million with a per Job Order Agreement limit of $4 million, without additional Council approval to exceed this limit. By using this master agreement to expedite repairs to the bridge, it has utilized a significant portion of the capacity from the original authorization. Increasing the capacity of the master agreement will allow for its continued use through the remainder of its five-year term.
Hunter Contracting Co's services include, but are not limited to: emergency design and reconstruction of the bridge, demolition of the existing damaged portions of the bridge, gas line removal, waterline repair, electrical, traffic control, environmental regulations, Rio Salado Path repair, and plant salvage and replacement. This amendment will provide additional funds to the Agreement.
Contract Term
The term of the master agreement will not change. Work scope identified and incorporated into the agreement prior to the end of the term may be agreed to by the parties, and work may extend past the termination of the agreement. No additional changes may be executed after the end of the term.
Financial Impact
- The initial master agreement for Bridge and Dam Safety Repair Program Job Order Contracting Services was authorized for a fee not to exceed $15 million, including all subcontractor and reimbursable costs.
- This amendment will increase the authorization for the master agreement by an additional $5 million, for a new total not-to-exceed master agreement value of $20 million, including all subcontractor and reimbursable costs.
Funding for this amendment is available in the Street Transportation Department's Capital Improvement Program budget. The Budget and Research Department will separately review and approve funding availability prior to the execution of any job order agreements. Payments may be made up to agreement limits for all rendered agreement services, which may extend past the agreement termination.
