Naval Facilities Engineering Systems Command (NAVFAC) Marianas announced a five-year $330.5 million, with potential contract options that would increase the final total to $560 million, award for repairs to Guam’s Glass Breakwater on October 12, 2024.
The design-build contract was awarded to TPC-NAN, a joint venture with Nan, Inc. and Tutor Perini Corporation, which is one of five Shipyard Infrastructure Optimization Program (SIOP) Multiple Award Construction Contract (MACC) holders.
The Glass Breakwater protects against tides, currents and storm surges, providing a safe harbor to the Port of Guam even during poor sea state conditions. The coastal structure suffered major damage by Typhoon Mawar in 2023, is currently classified as failed by US Army Corps of Engineers damage criteria and is at risk of a breach from another strong storm.
Without the breakwater, incoming marine traffic would have to standby offshore until conditions within Outer Apra Harbor become suitable. This could delay deliveries for critical medical supplies, fuels for power generation and transportation, construction materials, household goods, equipment and more.
By focusing attention on the longevity of the breakwater, the Navy is protecting and sustaining the wellbeing of our community and our island.
The award includes repairs to the three most critically failed portions of the Glass Breakwater to minimize future breaching potential of the breakwater. Pending future funding, the project may also include repairing the full length of the Glass Breakwater armoring from the head to Luminao Reef.
