Owings Mills Town Center Garage

Bonded post-tensioning is an ideal reinforcement for heavily trafficked parking garages, like the one at Owings Mill Town Center. Located near Baltimore, the Owings Mills Town Center is a mixed-use development that includes residential, office, retail and restaurant spaces, a public library and a community college building.

Bonded post-tensioning was used to construct this eight-story garage with over 2,800 spaces. Bonded post-tensioning provided the advantage of long-term durability for the structure and afforded the best solution for the owner’s requirements of maximizing durability and mitigating repair and maintenance costs over the garage’s lifespan.

VSLAB+^® bonded post-tensioning systems were specified for the garage’s decks and ECI bonded post-tensioning systems were specified for the beams. Plastic ducts in the slabs and beams provided enhanced corrosion protection for the post-tensioning tendons. STRUCTURAL TECHNOLOGIES supplied more than 2 million linear feet of post-tensioning strand, 600,000 linear feet of plastic corrugated duct, 8,700 VSLAB+^® anchorage systems, and 600 ECI anchorage systems for installation of the bonded slab tendons and bonded beam tendons.

In addition to supplying all of the materials and equipment for the post-tensioning installation, STRUCTURAL TECHNOLOGIES provided the shop drawings and engineering calculations.

The project also required the installation of a barrier cable system.  STRUCTURAL TECHNOLOGIES supplied cast in plastic encapsulated monostrand anchors and internal grabb-it rails with grabb-its.  To provide support and QA/QC for the contractor, the team provided an onsite superintendent to oversee the installation of the system.  Additionally, STRUCTURAL TECHNOLOGIES provided engineering/detailing through conflicts with the barrier cable anchors, multistrand anchors and rebar in various locations. Over 70,000 ft of .5 galvanized barrier cable was installed on the project.  All of the work was completed in less than one year.
