Civil Site Development

We performed the civil and riverbank restoration work as the civil contractor for the Vancouver Waterfront Project. The construction of the riverbank, park, commercial buildings, and new apartment buildings in the place of an old industrial site required critical pre-planning and seamless coordination between all contractors on the limited site and staging areas.

Starting with the installation of a new storm system, Tapani installed approximately 500 LF of 6”-24” storm pipe and associated manholes. Working up to the November in-water work window, Tapani also moved approximately 18,000 CY in cut and fills while mass grading the 7 acre future park and boardwalk area.

Crews also performed major riverbank restoration work during the in-water work window. Our crews took careful measures to prevent water pollution by installing a 2,200 foot long floating turbidity curtain. Because the site was once an old mill, Tapani removed concrete rubble, slabs, 47 concrete piles, and old pieces of concrete mill equipment from the riverbank, later integrating some of the historic pieces into the park itself. We also performed minor bank re-grading, placing over 2,500 yards of erosion control fabric, 1,950 tons of stream bed cobble, 1,930 tons bedding stone, and 23,200 tons of armor stone (boulders), creating a layered river-bank wall along the entire length of the park. In addition, Tapani crews constructed over 1,000 tons of Gabion basket retaining walls.

Our civil crew also worked on the hardscape which included hydroseeding, placement of 147 of Oregon Basalt stones from Moses Lake, construction of 1,780 square feet of playground, 66,000 square feet of sidewalk, custom hardwood platforms, plumbing system for the future water fountain feature, and landscaping. Our structural team built a vault and cistern for the water feature, a cantilever lookout over the water at the western edge of the park, and fabricated a stainless steel handrail to go along the entirety of the gabion wall.
