🌊 Something exciting is rising along the Columbia River in Washougal, Washington.

And Conco is proud to be part of it.

The HYAS Point development is the first phase of a multi-phased riverfront community that will bring new mixed-use commercial and residential space to the area. Phase one includes four mixed-use buildings, helping shape a vibrant destination for the growing Washougal community.

When LMC Construction approached Conco about the project, it came with a challenge: a fast start and an ambitious schedule. Our crews didn’t just meet the challenge, they delivered ahead of schedule, completing the project more than a month early.

💥 Project by the numbers

▪ 159,310 SF of finished concrete

▪ 9,600 cubic yards of concrete placed

▪ 1,349,310 pounds of rebar installed

▪ 209,262 linear feet of post-tension cable

From concrete pumping and formwork to post-tension systems, shotcrete shear walls, CIP columns, stem walls, and elevated PT decks, Conco’s team helped bring the foundation of this exciting development to life. Rebar installation for the project was performed by R2M2.

👏 Huge credit to the crews in the field and our project partners who made it happen:

-RKM Development
-LMC Construction
-TM Rippey Consulting Engineers
-YBA Architects

Great projects happen when strong teams come together, and HYAS Point is a great example of that.
