Dock, Pier and Boat Lift Engineering
Stamped design for docks, piers, boathouses and boat lifts where permits require engineered pile and load design.
What the work involves
Larger docks, boathouses, covered lifts and commercial marinas typically need engineered pile embedment, framing and connections for live loads, wind and waves. Engineers also assess existing docks after storms. Permit drawings are usually needed for state and federal approvals.
Local conditions we plan for
- Deep frost penetration
- Expansive clay soils (Pierre Shale)
- Riverine flooding
- Snow and wind loads
Building code: 2021 IBC/IRC adopted at the state level (ICC adoption chart, April 2026). A legislative summary reports adoption of the 2024 IBC and IRC effective July 1, 2026.
