Nine local projects win ASCE awards
By JOURNAL STAFF
The Seattle chapter of the American Society for Civil Engineers gave nine awards to projects for excellence in design in the 10th annual Local Outstanding Civil Engineering Achievement Awards.
Structures - outstanding award
Benson Road bridge, Renton
As part of the I-405 corridor improvements, WSDOT is building the Renton Stage 2 project, a half-diamond interchange on I-405 east of the I-405/SR 167 interchange at Talbot Road. The Benson Road bridge replacement is a 520-foot-long, three-span bridge constructed with WF100PTG spliced, post-tensioned prestressed girders, the first application of these girders in the state. Construction cost was $6 million.

Geotechnical - outstanding award
Structures - honor award
Pike Place Market renovation, Seattle
Phased work at Pike Place Market will repair and replace the mechanical, plumbing and electrical infrastructure, perform structural upgrades and provide new public restrooms and elevators. Phase 1A involved demolition, excavation, site utilities, earth retention and structural upgrades during the peak tourist season on a site that is only 80 feet by 90 feet in plan dimension. Construction cost was $2.4 million.

Transportation and development - outstanding award
Fraser Street Bike and Pedestrian Improvements, Bellingham
The project connects key bicycle and pedestrian facilities through a sensitive wetland corridor while using innovative stormwater management and low-impact construction. The bike lane consisted of rebuilding roadway shoulders using a structural cellular containment system with a passive linear sand filter and crushed-rock pre-treatment shoulders. An elevated pedestrian boardwalk with pin-pile foundations minimizes the impact on wetlands. The project also expanded lighting. Construction cost was $630,000.

Structures - honor award
NE 10th Street Bridge, Bellevue
WSDOT, the city of Bellevue, and HNTB led the I-405 GEC Team that worked with Scarcella Brothers and Max J. Kuney Co. to complete the bridge on schedule and under budget. The steel bridge connects 112th Avenue Northeast to 114th Avenue Northeast. It was paid for with local funds and state gas tax. The project involved construction of a stormwater detention pond, vaults and conveyance systems, roadway widening and intersection modifications, new traffic signals, EPS geofoam, a subsurface pedestrian bridge, landscaping and amenities. It was constructed to fit between the footprints of two hospital construction projects being built at the same time. Northeast 10th Street provides a new local access to the medical district from downtown. Construction cost was $21 million.

Small project and non-construction study - honor award
Carpenter Creek Bridge repair, Snohomish County
The storms in January of 2009 and flooding of Carpenter Creek created an emergency because the private bridge — sole access for 22 homes — was in jeopardy of collapse. The homeowners association worked with the engineer to create a rapid repair design using readily available materials and completed the repair with only two days closure. The construction cost was $59,500.

Transportation and development - honor award
14th Street Bridge over Fishtrap Creek, Lynden
The new bridge over Fishtrap Creek uses typical bridge materials in an innovative manner to create a unique structure, including a bridge deck curved with a 190-foot radius supported on straight precast concrete bridge girders. Safety was improved with lane widening and addition of sidewalks, shoulders, the curved deck and lighting. The project uses vegetated faced structural earth walls, a widened creek opening and lighting fixtures that match historic features in the city. Construction cost was $1.4 million.

Geotechnical - honor award
Elwa River Bridge approach, Clallam County
The project consists of a curved MSE reinforced slope constructed on a steep rock face to serve as the approach abutment for the west approach of the bridge. The rock face was created after an access road was benched into the rock face to provide access to a pier location near the river. Construction cost was $1.1 million.
ASCE entry engineer: Thomas Gurtowski and Matthew Gibson
Designer: Shannon & Wilson and Parsons/RCI
Owner: Clallam County
Ports and waterways - honor award
Dakota Creek Shipyard, Anacortes
The project is a redevelopment and expansion of Dakota Creek Industries shipyard. It includes two new deep water berths; new bulkheads and a heavy load pier; additional upland space; utilities, stormwater systems and an outfall; dredging/excavation; riprap slope protection; and relocation of shipyard structures. Construction cost was $20 million.
