Saipan and Rota Airport Inspection Facilities, CNMI

Gilbane executes the first international airport project funded by DHS/CBP at Saipan and Rota Airports in the Commonwealth of Northern Mariana Islands.

Work Coordinated to Allow Airports to Fully Function During Construction

The design-build renovation to the existing inspection facilities at Saipan and Rota International Airports was performed to meet Department of Homeland Security (DHS), Customs and Border Protection (CBP), and Immigration and Customs Enforcement (ICE) design and security standards.

Work was phased to allow full operation of the Saipan and Rota International Airports during renovation. This included maintaining passenger access and traffic flow and all utilities. We coordinated with the Commonwealth Port Authority (CPA) to work around the airports’ flight schedules and executed major scope elements, such as demolition, during off-peak hours to minimize disruptions to the processing of passengers.

Tropical storms, rough seas, and Tsunami warnings during construction were a major cause of project delays, warranting work stoppages and preventing material deliveries from arriving at the site on time. To ensure timeliness and avoid costs, Gilbane developed a comprehensive, site-specific Logistics Plan. We ordered long-lead items early; maximized the use of local labor, equipment, and materials; and clearly defined quality expectations at the project start to prevent rework.

Client Value

The collaborative project team incorporated input from many stakeholders to produce a cost-effective, buildable design that accounted for the CNMI’s remote location and available resources. Weekly coordination calls were held with United States Army Corps of Engineers (USACE) and the CBP during the design to resolve outstanding issues and minimize rework during construction.

Gilbane achieved a $2 million cost savings for the Government by utilizing available space within the primary arrival area for the placement of an administration section instead of building an additional structure.
