This project located in Vancouver, Wash., involved widening NE 94th Avenue from NE Padden Parkway to NE 99th Street from two lanes to three and included bicycle lanes and sidewalks. New traffic signals were installed on Padden Parkway and NE 94th Avenue. Primary work included constructing stormwater collection treatment systems, sewer lines, water lines, road surfacing, cement concrete curb, gutter and sidewalk, pavement markings and associated work. The project included almost 6,000 tons of asphalt, 1,520 square yards of impervious sidewalk and 640 square yards of pervious sidewalk, 2,250 lineal feet of curb and gutter, 800 lineal feet of traffic curb, 540 square yards of driveways and approaches, 6,100 lineal feet of 8-inch and 10-inch storm pipe, 290 lineal feet of 6-inch, 8-inch, and 12-inch water main, and 970 lineal feet of 4-inch, 8-inch, and 24-inch sanitary sewer pipe.
Due to heavy traffic on Padden Parkway (over 18,000 vehicles per day), lane closures were not allowed, which made building the new turn pockets from Padden Parkway onto 94th Avenue much more difficult. Tapani designed and executed a staging plan which allowed flagging on NE 94th Avenue only. For road reconstructs, working with the busy schedules of utility companies often causes project delays. Tapani coordinated all work with Clark Public Utilities, Comcast, CenturyLink, and NW Natural so all their construction improvements would be completed concurrently with Tapani’s contract work.
Clark County was very pleased with Tapani’s performance and wrote a letter of appreciation and commendation for Tapani’s performance.
