Tilt-Up was the best option for meeting this project’s needs including speed, economy and durability. The complex job involved several challenges.

Environmentally, the job site property was located partially on wetlands and partially on a dry, desert-like piece of land. As a result, the site was either muddy or dusty much of the time. To help alleviate this, the team constructed a series of temporary moats and ditches to handle the drainage after rainstorms. On dry days, workers donned protective dust masks.

With the closest source of concrete more than 45 minutes away, the team overcame another challenge by carefully scheduling early morning pours, some as early as 2 a.m.

A third challenge was the tight job site, which was handled through unique and carefully designed casting slab placements and maximum use of the main slab. A higher strength ready mixed concrete was used in all wall panels and the gymnasium walls were hardened and constructed as a hurricane shelter.

The uniquely designed panels feature an attractive ribbed finish. The peaked roof system of the administration building makes it stand apart from the typical institutional structure. Formliners were used to make depressions and an interesting pattern on the outside walls. These patterns had to be carefully matched between each panel. This eight building complex was completed within 20 weeks and opened on time for the new school year.

The campus includes eight separate buildings connected by covered walkways and accented throughout with concrete planters and features. The classroom building is two stories and the gymnasium is higher than a typical structure of its kind. The campus also includes a full-size auditorium.

About the TCA

Founded in 1986, the Tilt-Up Concrete Association (TCA) strives to improve the quality and acceptance of site-cast Tilt-Up construction, a method in which concrete wall panels are cast on-site and tilted into place. Tilt-Up construction is one of the fastest growing industries in the United States, combining the advantages of reasonable cost with low maintenance, durability, speed of construction and minimal capital investment. At least 10,000 buildings, enclosing more than 650 million square feet, are constructed each year using this construction method.
