East D Street Grade Separation Project, Tacoma, Washington

 

East D Street
Downtown Bremerton
Port Angeles 8th Street Bridges
SDOT NE 45th Street
Port Angeles Gateway
NAVFAC SW Hangar 1
APOE-Air Passenger Terminal
Portofino Mixed Use Building
 
   

Exeltech provided overall management, coordination, environmental assessment documents, and preliminary and final design for all aspects of this critical FAST corridor project for the City of Tacoma. This project required the development of six alternatives requiring a public involvement process building consensus early on. Exeltech provided bridge design services including a full TS&L and PS&E for this grade separation project.

As the prime consultant, Exeltech led a team of scientists and planners in the preparation of a NEPA Environmental Assessment that resulted in a finding of no significant impact within the schedule. All permit applications were prepared and coordinated by Exeltech.

Downtown Bremerton Pedestrian/BTC Improvements & NEPA Environmental Assessment, Bremerton, Washington

 
   
     
 

Exeltech provided structural and civil design, environmental analysis and documentation, and construction support services for this $34M multi-modal project to improve pedestrian, bicycle, transit and vehicular circulation and safety in the downtown Bremerton core.

The major structural elements of this project included constructing a 970-foot, cut-and-cover tunnel utilizing precast, prestressed roof panels, for vehicles exiting the Washington State Ferries terminal. Civil features included preparing preliminary and final design for roadway widening, access control, and improved horizontal and vertical alignments including curb, gutter, and sidewalk. This project also included NEPA Environmental Assessment, right-of-way acquisition, utility design, traffic analyses, streetscape and construction assistance.

8th Street Approaches, Port Angeles, Washington

 
   
     
 

Exeltech provided civil and structural design, construction management and inspection services for the replacement of two timber-trestle bridges located in Port Angeles. The project involved specific roadway improvements and improved approach design by adding over 800 feet of roadway approaches and sidewalks with curb, gutter and sidewalk from the two new bridge approaches to the existing city cross-streets.

Specific elements included funding development, implementation of a comprehensive public outreach program, environmental analysis, and the development and evaluation of eight bridge design alternatives. In addition, this project involved preliminary and final bridge, approach, foundation, streetscape, wetland mitigation and utility design as well as final decisions on streetscape and other aesthetic elements of the two structures.

Northeast 45th Street Viaduct TS&L/PS&E, Seattle, Washington

 
   
     
 

Exeltech is providing engineering consulting services to the Seattle Department of Transportation (SDOT) for the preparation of a type, size, and location (TS&L) report to replace the 730ft long 45th Street Viaduct. The ultimate goal of the project is to craft a context oriented solution that will incorporate and build on the Bridging the Gap (BTG) program goals. Factors taken into consideration include maintenance cost, seismic vulnerability, and pedestrian and bicycle safety among others.

Significant challenges on this project include traffic congestion, pedestrian safety, structurally deficient timber-trestle approach spans, funding, community outreach, and schedule constraints. Exeltech is addressing each of the challenges of this project using the most efficient and effective methods to advance the project.

International Gateway Project, Port Angeles, Washington

 
   
     
 

Exeltech is providing construction management jointly to Clallam Transit and the City of Port Angeles for the International Gateway project providing a central transfer facility. The new Gateway Center design accommodates public transit vehicles and includes parking for transit patrons and the public. It also includes restrooms, shelters, benches, bicycle racks, and information kiosks.

Exeltech is the primary consultant responsible for construction management and inspection, constructability reviews, inspection for grading, drainage, paving and structures; project management; technical evaluation of claims; project issue resolution; and quality control surveillance of process.

NAVFAC SW Hangar 1 Projects, Moffett Field, California

 
   
     
 

Exeltech completed a Gravity, Seismic and Wind Vulnerability study of the historic Hangar 1 (approx. total area 400,000 sq. ft) at Moffett Field. Hangar 1 is a massive structure approx. 1200 feet long, 200 feet tall and 300 feet wide. It was built in 1932 using multiple 3 hinged arches to house the airship USS Macon. The power-operated clamshell doors on the north and south end of the structures were used as entrance/exit for the blimp.

The study also included evaluation of subsurface condition including liquefaction and its impact on the analysis of structure and its foundation system. Exeltech developed computer generated 3-D models of Hangar 1 using commercially available structural analysis software to accurately analyze the structure.

Portofino Mixed Use Building, Seattle, Washington

 
   
     
 

Exeltech provided engineering services including gravity and lateral design of this five-story building in Lake Union, Seattle. The total floor area of the building is approximately 40,000 square feet out of which 22,000 square feet is residential space and the rest is for parking and commercial space. The building consists of a concrete garage, commercial space and wood frame residential floors. Exeltech was also retained to provide construction support services for the project. The building is also very close to adjacent property lines.
