1. Contracting Activity

Naval Facilities Engineering Command (NAVFAC Marianas), Naval Base Guam (NBG), Resident Officer in Charge of Construction (ROICC) Guam, South.
2. Description of the Action Being Approved
Award a contract modification on a sole-source basis to Tutor Perini Corporation Nan Inc. A Joint Venture (TPC-NAN JV) under contract N62742-22-D-1314-N4019225F4003, the contractor currently performing waterfront and breakwater repairs at Apra Harbor, Guam, for damage sustained from Typhoon Mawar in May 2023. This contract modification is for critical emergency waterfront stabilization repairs at Apra Harbor for damage caused by Typhoon Sinlaku using $19,624,552.00 fiscal year 2026 (FY26) funding. This modification will be executed under the authority of 10 U.S.C. § 3406(c)(1), Unusual and Compelling Urgency. This period of performance for this modification is not expected to exceed one year.

3. Description of Supplies/Services

This modification covers additional work required to make immediate emergency waterfront stabilization repairs for damage caused by Typhoon Sinlaku to the Glass Breakwater in April 2026. Following Typhoon Sinlaku, the Government took immediate action through an initial modification to authorize placement of 20k tons of stone needed for emergency repairs based on initial assessments and procure a survey to understand the extent of the damage. However, before the full scope of repairs could be determined, Guam was impacted by a second storm, Typhoon Bavi, in July 2026. Due to the short time frame between Typhoon Sinlaku and Typhoon Bavi, it took the designers time to identify and segregate requirements attributable to the emergency repairs under each storm. Based on the results of the survey, it was determined that additional armor stone is required to complete stabilization requirements as tied to Typhoon Sinlaku. This FY26 emergency waterfront stabilization repair constitutes a bona fide need of FY26 and its estimated value is $19,624,552.00 which is approximately three (3) percent (%) of the total contract value. Under this modification, the contractor shall procure/place additional critical armor stone to mitigate active breaches caused by Typhoon Sinlaku.
