Lima Wharf

Apra Harbor, Guam
H2O Guam JV, a joint venture between Weeks Marine subsidiary, Healy Tibbitts Builders, Inc. (managing partner), Hawaiian Dredging Construction Company and Obayashi Corporation successfully delivered the Lima Wharf, Naval Base Guam Project.

This major marine infrastructure initiative was designed to enhance U.S. Navy port capabilities and resilience. The project scope included:

  • Construction of a new wharf featuring a steel king pile/sheet pile bulkhead system with concrete capping beam
  • Installation of a pile-supported concrete anchor wall and tie-back system to ensure long-term structural stability
  • Ground improvement using stone columns to support heavy marine operations
  • Deployment of a heavy weather mooring system, including 300-ton capacity mooring bollards and fender system with precast concrete piles for vessel safety and durability
  • Integration of cathodic protection to mitigate corrosion and extend asset life
  • Construction of an electrical substation and Bilge Oily Waste Treatment System (BOWTS) plant to support operational efficiency and environmental compliance
  • Installation of wharf utilities, lighting and asphalt concrete pavement to complete the facility’s functionality

 

The $104.8 million project was completed in 2025. It strengthens marine logistics, improves environmental safeguards and provides long-term Navy mission critical support in the region.
