Naval Base Kitsap-Bangor
Silverdale, WashSilverdale, WA
At Naval Base Kitsap-Bangor, the Department of the Navy set out to install a new operations and refit maintenance facility on the Delta Pier Submarine facility located within the controlled area of Naval Kitsap Base, Bangor. The Delta Pier was already at capacity with buildings and usage and needed plenty of additional storage as well for a stronger operational readiness of our Naval Nuclear fleet.
CMS Construction, based out of Maumee Ohio, was awarded the contract as the contracts prime contractor, and Tunista Construction as the primary Civil contractor on the team. For this project, Tunista has handled all earth moving and underground utilities, which included, but are not limited too new sewer, storm, fire, and domestic water, and were also installed on the Uplands side of the project, juggling the proximity to the Hood Canal waters, and having to work across the trestles for site accessibility and extremely challenging environmental erosion and storm management conditions.
One of the key conditions of this project, was the continuous use of the onsite installation and current infrastructure, and to not compromise, or remove the usage of the existing infrastructures utilities while performing the work. This required that utility outages, would be no longer than 4 hours as to not impact the utility being retrofitted, selectively demolished, or otherwise altered. The utility package installation also had an artesian well discharge assembly that is tidally influenced, with the requirement of timing around low tides and technically challenging crane work with lowering personnel over the cofferdam for discharge assembly installation. Tunista received a commanders coin for our safe performance.
Once that work was complete and subgrade was prepared for the storage rack installation, Tunista moved operations to the Delta Pier and began demolition for the new building. Existing buildings, hardscapes, and utilities were cleared and or rerouted in the vicinity of the new facility to be built. Once excavation and export were completed, Tunista also assisted with management of drilling spoils and slurry in the large-scale drilling operations that took place to get the concrete piers installed that are now supporting the building.
