Location: Tacoma, WA
Client: Washington Dept. of Transportation
General Contractor: Hamilton Construction Company
Project Cost: $300,000

The Conco Companies is providing shotcrete services for the new I-5NB HOV lane that runs from Portland Avenue to the Port of Tacoma Road in Tacoma, WA. We will be using a specialty shotcrete technique to carve a design on the shot-face of the retaining walls. By implementing this technique over a traditional cast-in-place approach, it will save the project an enormous amount of both time and labor costs. Furthermore to increase efficiency, our crews are doing all of the carving from lifts.

The full scope of the project includes widening the I-5 to make room for the HOV lane as well as the construction of a couple of bridges, the reconstruction and improvement of several interchanges along the route, and repaving all of the lanes.

The project is expected to be completed by mid-2018 and will provide motorists with numerous benefits including improving the highway’s overall safety and traffic flow as well as environmental enhancements. In addition the I-5 will receive an Intelligent Transportation System (ITS) upgrade that will make it possible for WSDOT to respond more quickly to accidents and other type of incidents to help reduce traffic delays.

Ankrom Moisan Architects designed the new building to enhance the conference amenities currently available in the city, which will include a 10,000 sq. ft. grand ballroom and 9,000 sq. ft. of other function rooms within the hotel.

Conco’s extensive services include concrete pumping, reinforcement, formwork, shotcrete, and finishing. As the project will be the largest one in the city, Conco was selected for the job due to our extensive portfolio of big projects as well as our ability to handle an aggressive schedule. In fact, one of our first projects in the Northwest was the Tacoma Marriott Hotel in 2004, which is located across the street from the new job site. Scheduled to open in the summer of 2019, the high-rise will be the second tallest building in the city.
