The Typhoon Pongsona rebuild of the Hyatt Regency Guam Hotel was a project undertaken by Black Construction Corporation that dramatically expanded from an original $2,000,000, 90-day contract to $3,700,000 with completion in September 2003 instead of the originally-intended June 2003 date. The control issue of the total scope of work was mold remediation prior to damage rehabilitation. The rebuild was primarily confined to interior restoration of the guest rooms, guest room corridor, guest and service elevators, lobbies and back-of-house areas, which included the main administration location.
