Epic Tower Project Update - The Conco Companies

The Conco Companies topped off the new mid-rise Epic Tower in February 2019. Conco provided all cast-in-place concrete services, including finishing, formwork, pumping and shotcrete.

Developed by Hudson Pacific Properties and designed Gensler Architects and Nabih Yousef and Associates, the project, under Hathaway Dinwiddie features a 14-story tower with 300,000 square feet of office space, 18,400 square feet of new retail space, and 5 levels of structured parking. The $150 million-dollar development will be an expansion to the Sunset Bronson Studios Complex directly across the street.

The unique building includes terraces at every level with modern appearance landscapes, providing a seamless transition to outside workspaces through tall glass walls that overlook the city of Los Angeles. Office space features new 15-foot lower profile ceilings with open floorplans.

The project started in December 2017 and presented logistic challenges due to its location, high volume of traffic, and limited site access.  Epic Tower took nearly 43,000 cubic yards (cy) of concrete to be completed. A total of 11,000 cy was poured on footings and 12-foot mat slabs surrounding the concrete core. The methods used to place mass concrete had to be taken into consideration with thermal control plans.  Vertical elements on the structure such as columns and the concrete core tower required a 7,000 PSI and a high modulus of elasticity (MOE).

To overcome these challenges, Catalina Pacific provided a mix design using Orca rock and provided a mix that would reach nearly 9,000 PSI at 56 days.  The concrete decks which comprised 50% of the overall yardage of the project, also had high requirements on MOE and Orca rock with a 6,000 PSI requirement. Additional challenges included a 10-foot cantilever deck, which was completed successfully by our formwork team.

Conco was selected for this project because of our experience and commitment to high-quality planning and execution on complex projects.
