609 Main at Texas

50-LEVEL, CLASS A TROPHY OFFICE TOWER

Houston, Texas

The LEED Platinum-certified 609 Main at Texas is a 50-level, Class A “trophy” office tower and a highly visible landmark in Houston’s central business district, with a unique glazed façade that reflects the sky and sweeps along the changing elevations of the boulevard. The building has 12 levels of parking below the office structure and an adjacent free-standing 12-level parking garage with two of the levels below grade.

Ceco provided concrete formwork services for this tower and garage project, working with the project team to take maximum advantage of the site’s tight downtown footprint. Using wide module pan construction for the office tower, Ceco engineers and field forces customized the longform pan system to achieve an eight-day cycle per floor; each office level measures approximately 28,000 square feet. The wide module, one-way joist system made possible the structural engineer’s desired design loads and reduced vibration. Pan construction also creates long slab spans, which enabled the flexible, open floor space needed for the office tower.

For the parking garage, Ceco used beam-and-slab concrete formwork. Other formwork systems used for the project included perimeter tables and interior beam tables for beams and girders, soffits and support. In addition, Ceco used a perimeter cantilevered debris netting system to catch potential falling objects, thereby protecting passersby on the busy downtown streets below.

In all, Ceco provided formwork services for elevated decks, columns, sloping columns, shear walls, and one-sided basement walls, which included placing concrete in the columns and walls.
