LKB completed the replacement of 2,850 linear feet of bulkhead located within an active marina and park facility that includes swimming pools, ball fields and picnic areas. The deteriorated timber bulkhead was partially removed, and new composite sheet piling was installed in front of the remaining bulkhead. The new bulkhead was connected to the existing deadman system with tiebacks and an integrally poured-in-place concrete pile cap was installed. New asphalt walkways, curbs and railings (attached to the pile cap) were constructed along the perimeter of the bulkhead. Utility upgrades included replacement of the lighting system and new electrical and water services to the floating docks. The construction was performed in phases during the off season in order to accommodate boaters and ensure the marina was operational at the start of the boating season.
In addition to design of the bulkhead, the engineering services included providing a topographical survey, subsurface investigations, electrical service inspection, bulkhead and concrete deadman tieback inspections, permitting, and construction inspection services.
