The companies and the Navy announced in October that the U.S. Navy had chosen a cooperative venture of Tutor Perini Corp. and Nan Inc. to fix a shoreline at Naval Base Guam that was damaged last month when Typhoon Mawar struck the country. The contract has a base price of$ 330.6 million, but lease options could increase its value to about$ 560 million if exercised.
The 3-mile-long Glass Breakwater crosses Apra Harbor, which is used by both the defense and the Port of Guam, to connect the northern part of the interface. It helps guard against tides, currents and storm surge. But it” suffered major damage” during the typhoon and is now classified as failed by the U. S. Army Corps of Engineers, according to Naval Facilities Engineering Systems Command ( NAVFAC ) Marianas. According to Navy officials, the shoreline could break during a second strong wind.
Vice Admiral Jeffrey Jablon stated during a Senate subcommittee hearing in May that “if that]breakwater ] breaches, the inbound and outbound traffic going to Arpa Harbor will not be permitted to go in.” ” That includes our ships, our Navy floor ships, our submarine contracts that are stationed it. So it’s important to activities in Guam”.
The Category 4 storms struck Guam in May 2023 with continual winds of 130-140 speed, 72 in. of rains and storm wave of up to 12-14 feet, according to the National Oceanic and Atmospheric Administration.
At the Senate receiving in May, Jablon said the storms “did a lot of harm to our vital system”. At the time, he estimated the cost of the breakwater repairs at$ 600 million, and repairs to a helicopter squadron hangar at$ 580 million. Additionally, U.S. Air Force representatives gave evidence of having higher costs for maintenance following the storm.
The five-year deal’s range is focused on three of the most thoroughly failed regions of the seawall, according to NAVFAC Marianas, which awarded the contract Oct. 12. Given potential revenue for the other lease alternatives, it could include repairing the building’s full length.
Design is currently being worked on, with the goal of completing the project by July 2029 and beginning in-water function in August.
Capt. said,” This initiative will provide crucial infrastructure improvements that will enhance our endurance against natural disasters and support the lives of our occupants.” Troy Brown, NAVFAC Marianas commanding officer, in a speech.
The Sylmar, Calif. based joint venture of Tutor Perini and Nan, named TPC-NAN, is one of five Shipyard Infrastructure Optimization Program ( SIOP) multiple award construction contract holders, according to NAVFAC Marianas. Tutor Perini said in a speech that its Guam-based company, Black Construction Corp., may manage work on the project. In 2013, Black had recently completed a smaller maintenance task on a part of the Glass Breakwater.
The storms and subsequent upgrades come amid a drive to build up the U. S. government’s appearance on Guam. On October 30th, Granite made the announcement that NAVFAC had chosen it for a$ 42 million design-build contract for the construction of the missile defense and security systems at Naval basic Guam. That job is expected to be finished in August 2026.
