Construction trends come and go. Best practices of today may be out of style a decade from now (or sooner). With that said, there are three underlying drivers that spur evolution in residential development and remain guiding lights for each generation of construction professionals:
- Buildings must be affordable
- Buildings must go up quickly
- Buildings must be high-performing
Given unprecedented affordable housing challenges and tightening environmental/safety regulations as we kickoff 2025, architects and design professionals are finding it more challenging than ever to find solutions that can satisfy these diverse factors.
Enter prefabrication processes.
Given its utility in fast, precise construction, it offers many advantages for keeping urban development projects on time and under budget. In addition, prefabrication processes yield many sustainability benefits that traditional on-site construction methods cannot match. Keep reading as we explore prefabrication from all angles and shed light on its crucial role in the future of urban development.
Benefits of Prefabrication Processes
Prefabrication, or the act of constructing building components or entire buildings off-site and transporting them to their final location for assembly, offers several advantages over traditional on-site construction.
Solution to Labor Shortages
According to the Association for Builders and Contractors, the construction industry faces a shortfall of nearly 500,000 workers barring a significant–and unexpected–influx of talent into the industry.
The downfalls of this labor shortage are fairly obvious, affecting the cost and quality of construction projects. In some cases, it can forestall work altogether.
Prefabrication offers exciting potential for navigating workforce challenges.
Many types of prefab materials, such as louvered pergolas, steel buildings, and vinyl fence gate kit systems, leverage machinery and automation in the factory. On-site, most prefab components require far less preparation and foundation work, allowing for quicker, more efficient construction that requires smaller labor teams.
Conducive to the Industry’s Increased Digitization
As in all industries, the construction sector is leveraging technology as much as possible to improve processes. Augmented reality, 3D printing, dynamic BIM, and next-level project management software are just a few of the ways that technology is changing the game in construction.
By keeping a healthy portion of the construction process in a factory setting, architects are able to position key building components more proximate to technology, leading to increased efficiency of digital integration.
Reduced Construction Error
Even with outstanding planning, preparation, and construction management, there are numerous factors that can undermine an on-site residential development. A few of these include:
- Traffic
- Inclement weather
- Worker error
- Vandalism and theft
There is greater control over variables in off-site construction. By using prefabrication processes, professionals can be much more confident that they will avoid these frustrating setbacks that commonly impact building quality.
Sustainable Construction
All in all, prefabrication offers potential as a sustainable construction solution over traditional on-site building methods. Among the factors that contribute to prefabrication’s sustainability include:
- Shorter building times means less energy is consumed throughout the construction process
- Increased precision reduces the risk of construction waste and inefficient re-work scenarios
- Less fuel is consumed moving materials and workers back-and-forth in a piece-by-piece on-site project
While prefabrication will require more investment in facilities, its potential as a precise, streamlined option give it a major leg up in terms of sustainability.
Challenges of Prefab Construction in Urban Developments
Despite the vast potential of prefabrication in construction, there are a handful of considerations that designers and architects must effectively navigate for the process to continue to gain adoption in urban developments.
Local Building Codes
There are some local building codes that create challenges for prefab structures. Some examples may be cities that require more vigorous inspection on foundation strength, ada railing requirements, and fire resistance of the roofing products. As such, it is crucial to know local zoning laws and building codes before diving head-first into a prefab development.
Urban Logistics
Access to building sites can be difficult when constructing urban developments. Crowded sidewalks, narrow alleys, and bumper-to-bumper traffic are some challenges facing prefabricated structures. It can take careful coordination with city councils to obtain necessary access to building sites with oversize loads. In some cases, it may require transport during graveyard shifts and/or holidays.
Integration
There is a major trend toward rehabilitation in some urban areas. When the goal is to bring an existing structure up to modern standards, it can be difficult to find ways to incorporate prefabrication into the process. Although fully prefabricated buildings are not possible during a rehabilitation, there are many types of prefab “plug-and-play” components that can be used during a renovation. Some examples include commercial pipe insulation for the sewage system, hvac sound attenuators to stifle noise in old-fashioned utility rooms, and self-adhering drainage mats for foundation waterproofing.
Prefabrication: An Urban Construction Solution on the Rise
Architects and other construction professionals are constantly looking for ways to make buildings better, cheaper, and accessible more quickly. This is especially true in urban areas, where cost of living challenges are a fact of life for many residents. By leveraging the quick, precise construction afforded by prefabrication processes, construction professionals give themselves a leg up on these diverse challenges.
