Projects
Dams & Ports
Specialty geotechnical construction for dam, dock, wharf, and port improvements—where deep foundations, earth retention, ground improvement, and constrained access must work as one coordinated package.
Overview
Foundation Work at the Water’s Edge
Dam and marine infrastructure place specialty foundation work at the intersection of water, difficult access, saturated ground, existing utilities, and active operations. Pacific Foundation brings deep foundations, earth retention, and ground improvement methods to those conditions with field planning matched to the structure and construction sequence.
Over-Water Access
Barges, shoreline work, and restricted access can change equipment setup and sequence.
Saturated Ground
Water and loose or variable soils can drive casing, cutoff, or ground-improvement decisions.
Existing Utilities
Buried infrastructure must be understood before drilling, excavation, or treatment begins.
Active Facilities
Operating dams, ports, and waterfront facilities can limit staging, shutdowns, and work windows.
Rock and Obstructions
Rock sockets, boulders, and difficult drilling conditions can affect tooling and production assumptions.
Verification
Testing, inspection, and installation records should align with the foundation and retention plan.
Relevant Capabilities
Drilled Shafts & Rock Sockets
Large-diameter deep foundations for heavy structural loads, over-water work, and rock-socket requirements.
Micropiles
Small-diameter deep foundations for limited access, retrofit work, and difficult ground conditions.
Secant & Tangent Pile Walls
Overlapping or tangent drilled elements for earth retention, cutoff, and excavation support.
Soldier Pile Walls
Flexible shoring systems for excavations, constrained sites, and work beside existing infrastructure.
Jet Grouting
In-place soil treatment for ground improvement, cutoff, underpinning, and utility-sensitive work.
Deep Soil Mixing
Mixed soil-cement columns for ground improvement, support, and seepage-control applications.
Featured Projects
Dam & Port Project Experience
Haapa Fishing Platform Construction
Woodland, WA
Pacific Foundation installed sacrificial and production micropiles and proof tested them for the Haapa ADA Fishing Platform.
Lower Granite Dam
Pullman, WA
Thirty-two 54-inch drilled shafts with 48-inch rock sockets, installed through water, overburden, and hard bedrock.
Bull Run Dam 2 Tower Improvement
Bull Run, OR
Shotcrete support and grouting provided earth-retention support for improvements at the operating dam facility.
Foss Maritime Dock
Portland, OR
Barge-mounted predrilling used 36-inch temporary casing and grout to prepare foundations for permanent dock piles.
Lake Oswego River Intake Pump Station
Lake Oswego, OR
Pacific Foundation's documented scope includes secant piles.
Kapalama Wharf & Dredging Project
Honolulu, HI
Predrilling around utilities, cutter mixing, and jet grouting provided ground improvement for Honolulu Harbor infrastructure.
Pioneer Street Rail Overpass
Ridgefield, WA
Pacific Foundation supported the Pioneer Street Rail Overpass project with large-diameter drilled shafts.
Washington Park Reservoir
Portland, OR
Pacific Foundation supported the Washington Park Reservoir project with temporary and permanent soldier pile walls, tieback anchors, drilled shafts, dewatering, cathodic protection, instrumentation, tower-crane shafts, carved shotcrete, soil nail walls, and toe block anchors.
Pearl Harbor P-209 Dry Dock
Honolulu, HI
Deep cement mix columns, secant piles, and jet grouting around utilities supported phased marine work in an active yard.
