While pre-engineered metal buildings are commonly touted for their speed of construction and low initial cost, concrete tilt-up offers economical and cost-efficient options to building owners seeking investment grade properties. Tilt-up delivers distinct advantages related to durability and energy efficiency, which translates into long-term cost savings for the life of a building.
When evaluating a new building, consider the following.
|Superior thermal performance||It is important to understand the R-value of a finished system—not just the insulation itself—since metal buildings suffer from thermal bridges where wall and roof panels are connected to the structure. With tilt-up, continuous insulation combined with the thermal mass of concrete saves energy and operating dollars.|
|Bearing and shear walls on perimeter||Metal buildings require perimeter columns and steel bracing on the perimeter or interior, consuming valuable interior space and dictating the spacing of exterior openings. Tilt-up wall panels are load-bearing, which eliminates perimeter columns, maximizes usable interior space, and provides greater flexibility for locating exterior openings.|
|Continuous perimeter foundations||Tilt-up concrete walls are supported by continuous perimeter foundations, recognized as an extremely simple, cost-efficient construction process. Metal buildings, with their perimeter columns, need more costly and time-consuming foundations constructed of column pads and anchor bolts.|
|Reinforced concrete exterior||Metal siding typically found on metal buildings is easily damaged, whether on the exterior from weather and vandalism or on the interior from daily operations. Tilt-up’s concrete walls provide increased durability and security against weather and operations, minimizing maintenance and prolonging the life of a building.|
|Combined structure and cladding||Where a hard wall is desired, metal buildings provide the exterior structure only and require separate cladding for a completed shell – adding cost to the building shell. With tilt-up construction, the exterior walls perform as both structure and cladding.|
|Schedule flexibility||The schedule for a metal building is dependent on production at steel mills and fabrication plants, and requires that the walls be constructed only after the superstructure is erected. Tilt-up projects deliver greater schedule flexibility and faster completion, since tilt-up panels are constructed prior to the superstructure using locally-produced materials, saving as much as four weeks on a 100,000-square-foot building.|
