Prefabrication is the act of producing buildings or building modules at an off-site location while leveraging a factory type setting, better suited for construction. Prefab modules are often produced with an automobile assembly line type production methodology. Upon completion, large modules are transported to construction sites for installation. The modules are then connected with site built foundations, water, gas, electric utilities, etc. to create completed buildings. Offsite, manufactured, modular, etc. are all variations on Prefab type structures. The common thread is the off-site manufacture of buildings, typically assembled with repetitious components, material applications and processes, and then delivered to a project site for final installation and connection. The following benefits have prompted a new generation of forward thinkers to adopt and employ Prefab:
More for Your Dollar:
Prefabrication enables increased efficiency, reduced timelines and also eliminates construction errors – all of which results in a better building dollar value and often, a reduction in overall construction costs. This is the Prefab game changer. In general, consumer costs for prefab construction can be les expensive than stick-built projects by an average of 10 to 20% and sometimes more. Inherent to each Prefab process, there are specific cost and timing impact pros/cons. Prefab factories purchase materials in bulk, labor costs are typically less expensive because of highly controlled factory work conditions and a reduced time frame fuels a more cost efficient project. Design solutions often include interior finishes, appliances, lighting, etc. – a complete and finished building. Local governing agencies will dictate requirements for soft costs - building permits, neighborhood review, licensed architect drawings, soil testing, site surveys, utility hookups, etc. Selection and preparation of the job-site/property is critical to the overall budget. Flat vs. steep sloped property often determines inexpensive vs. expensive foundation costs. A good command of local labor, install and construction costs leads to a realistic project budget.
Fastest Design, Permitting & Construction Schedule:
Prefabrication can reduce project schedule by 50% compared to traditional construction. From “concept to keys”, the collective process is ideally coordinated under one umbrella/factory roof. The bulk of prefabricated buildings are pre-designed, pre-approved by governing agencies and efficiently assembled in factories – collectively resulting in tighter project timelines. The benefits of a reduced construction schedule are numerous with major advantages that ultimately translate into financial savings and/or gains.
Prefabrication employs various levels of tightly controlled factory settings, processes and tools resulting in quality control that is unsurpassed. Indoor fabrication facilities eliminate the negative impact of adverse weather/climate conditions on production. Prefab’s streamlined assembly processes reduce construction errors, re-work and even injuries. Construction site theft is non-existent and reliability of tools/logistics enables workers to focus on a product of the highest quality. A controlled setting, optimized for product manufacturing and on-going value engineering, captures efficiencies otherwise unachievable in traditional construction. Factory fabrication enables tighter tolerance of joints, connections and seams - improved precision and quality.
Save The Planet: Ten Prefab Environmental Benefits:
1. Reductions in construction Waste - more efficient factor controlled fabrication can reduce waste by over 50%
2. Materials are deliver in bulk resulting in less frequent deliveries to a factory - with streamlined transportation, gasoline consumption is largely reduced
3. Shorter project time translate into reduced carbon emissions across the entire spectrum of material supply & construction labor
4. Material waste is largely reduced, by at least 70% compared to conventional construction.
5. Less frequent demolition of inferior quality buildings - increased strength of modular buildings provides for a longer building life cycle
6. Energy consumption is reduced - factories control energy use/emissions in a superior manner to conventional construction sites
7. Reduction of site deliveries by up to 90% and a decrease is gasoline consumption - the average travel distance of workers to the site is reduced by 70%
8. Higher quality & installation of spray foam insulation translates into a reduction in energy consumption directly related to air conditioning and heating
9. High levels of moisture as a result of rain at site built projects is eliminated. Factory produced modules are immune to rain, snow and inclement weather
10. Requiring less space around the project site for workers, vehicles, construction materials & equipment, the on-site portion of the construction process is minimized. Factory based production results in greatly reduced disruption/noise/air pollution for adjacent neighbors:
An enviro-conscious prefab process can speed up timelines, increase productivity and improve quality - all at an affordable price-point.
