Moving Beyond the “Box” Perception
with PEMBs

From a design standpoint, a common misconception is that metal buildings are “boxy” or restrictive; however, this assumption is no longer accurate. On the contrary, architects and engineers can leverage the latest design and material innovations without compromising the speed and practicality that make metal buildings so appealing by initiating the process early and connecting the pre-engineered metal building (PEMB) design and fabrication process.

The advantages of automation

PEMB systems offer numerous benefits. By nature, they are efficient and quick to fabricate, due in part to the fact that manufacturers create them using standardized steel sections under tightly controlled conditions to ensure uniformity.

All components are pre-punched, pre-drilled, cut to length, and shop-primed, allowing for immediate assembly upon arrival at the jobsite. This streamlined fabrication process reduces field labor, minimizes errors, and accelerates construction schedules.

In addition, the fabrication process can include downloading job-specific data directly from design software into automated manufacturing systems across multiple product lines. This data is electronically processed and transmitted to production equipment, eliminating manual operator input, reducing downtime, and significantly minimizing fabrication errors.

Automation programs further improve machine efficiency and reduce material scrap, which in turn helps control raw material costs and deliver greater value to the customer.

PEMB systems are also quicker to raise compared to most alternatives because they arrive on-site already partially assembled, significantly reducing construction costs. As long as the design parameters are clear and in place, these systems also have predictable costs, minimizing the likelihood of unpleasant budget surprises that could potentially impact a project.

Unpacking the “box” perception

Some PEMB projects mandate speed and simplicity, and therefore lend themselves towards clean, rectangular systems. This approach suits certain straightforward projects, such as storage and manufacturing spaces; however, it can limit flexibility and reduce the range of design options available to architects.

A disconnect between design and fabrication early on in the design process can lead to a focus on standard configurations alone, limiting opportunities to explore alternatives. When this happens repeatedly, it leads to an influx of rigid, “boxy” buildings, even though other outcomes could have been feasible with earlier collaboration. When collaboration starts early on, manufacturers and architects can shape the building system while the design is still in flux, enabling the adjustment of rooflines, exterior features, and other elements to create an aesthetic that transcends the standard “box.”

Working with the metal building system plans early on helps architects recognize possibilities, necessary adjustments, and cost variables, whereas waiting until later can limit options, making it harder to create designs that move beyond a simple “box.” This provides more time to experiment with different aesthetic elements, panel and framing options, roof slopes and shapes, and material combinations, among other areas. In some cases, it may also make financial or structural sense to merge several PEMBs together into one structure, which can save space and money while reducing project complexity.

Complex design environments

Design expectations continue to evolve in many cities and towns, with a greater emphasis on aesthetic appeal and street presentation. Roof forms, facade variations, and similar elements often come into play, becoming increasingly important aspects of the approval process.

In other words, basic metal box-style buildings no longer meet the requirements in many municipalities, making it difficult, if not impossible, to secure approval for these projects.

Designing buildings today involves more moving parts than previously required, with many cities and towns now expecting more detailed documentation and buyers seeking structures that outperform and outlast those of earlier generations. Timelines and budgets are also shrinking, giving architects numerous considerations to juggle while working to preserve the original design intent.

Flexibility: the key to metal building success

Virtually every design change comes with cost implications. Costs can be seen as design drivers, rather than something restrictive. It is critical for all parties involved in the design process to know how to solve steel building design problems without busting a client’s budget. Teams can identify where flexibility exists in the specific PEMB system they are working with, which can involve elements like bay spacing and roof slopes, and how minor adjustments can help achieve a desired look without inflating the project’s price tag.

Architects can optimize PEMB efficiencies even when design standards are more demanding, and review processes become increasingly unpredictable. Through concept testing during early design phases, teams can explore numerous options while keeping costs manageable. This enables architects to respond to municipal feedback, refine their design intent, and address any design constraints before they impact budgets and schedules.

Flexibility is critical when projects evolve. Design requirements can change as a result of zoning reviews or site conditions, requiring adaptability in every stage of the design-build process.

The strongest PEMB systems do not regurgitate the same design and plan seen across the market. Instead, they are flexible, allowing structures to “move beyond the box” and create something truly striking.
