Using cold-formed steel framing (CFS), contractors are finding ways to build sustainable structures more efficiently, in less time and with lower costs. A Brief History of Prefabrication Houses have been built in one place and reassembled in another throughout history, says the National Parks Service. In 1830, the first prefabricated home was conceived in London. The house was built in components, then shipped and assembled by British emigrants. During the 1849 California Gold Rush, a roofer from New York advertised “portable iron houses for California.” According to the ad, “20’ x 15’ homes could be built in less than a day, were cheaper than wood, fireproof, and more comfortable than a tent.” The Good Housekeeping Stran-Steel House was constructed at the 1933 Chicago World’s Fair. The combination of double back-to-back channel members and a special nail design allowed the structure to be constructed quickly. In the first half of the 20th century, more than 370 designs were offered through mail order ready-to-assemble kit homes sold through the Sears catalog. “The novelty of prefab is not new, and what’s interesting is how many different levels of prefabrication are available,” says Luiza Mills, vice president of human resources and public relations at Interstate Electrical Services Corporation. “Prefab still has a connotation that it’s set on a dusty table in the back of someone’s warehouse, and that is not true.” The Steel Framing Advantage Cold-formed steel (CFS) leads the way as the preferred framing material for prefabricated structures for multiple reasons. CFS is: A pre-engineered material that can be cut to exact lengths Dimensionally stable and does not expand or contract with changes in moisture content Lightweight compared to wood and concrete Resilient and will not warp, split, crack or creep when exposed to the elements Sustainable and 100% recyclable Durabile and has a high tensile strength Non-combustible and is a safeguard against fire accidents Prefabricated and Modular Construction on the Rise According to Dodge Data & Analytics, contractors are increasing their use of prefabrication and modular construction techniques in the commercial sector: 25% invested in prefabricated projects (will increase to 33% in next 3 years) 17% bid using modular techniques (wil increase to 21% in next 3 years) $68 billion value of modular construction in 2019 (will reach $106 billion by 2027) Improved productivity, improved quality, increased schedule certainty and reduced waste are just a few benefits of prefabrication and modular construction, says Construction Executive. The Metreau Apartments in Green Bay, Wisconsin featured 11,508 lineal feet of prefabricated cold-formed steel (CFS) wall panels from Wall-tech. By panelizing the entire job, the owner received the building earlier and saved $250,000 in construction and carrying costs. Modular vs. Prefabrication: What is the Difference? According to Acuity Insurance, prefabrication is a general term used for a building component that is manufactured in a factory prior to its final assembly at the construction site. Modular construction refers to something built or organized in self-contained units — like building blocks. A modular structure is at least 70% finished in the factory prior to delivery to the construction site. All modular buildings are considered prefabs, but not all prefabs are considered modular. Prefabrication Has Become ‘Normal’ To satisfy the needs of customers and to address the existing labor shortage, contractors are embracing modular and prefabricated construction practices at record levels. “Construction is near a point where prefabrication and modular have become a lot more normal,” says Jake Snyder, director of preconstruction at Hoar Construction. “Owners want schedule and budget certainty earlier in the process and projects to be completed at a faster pace. Prefabrication solves these problems.” An example of successful prefabrication is South Valley Prefab’s work at Catbird, a seven-story, 165-unit, extended-stay hotel in Denver, Colorado. South Valley Prefab prefabricated 277 individual CFS exterior finish panels a month prior to installation Only six installers were needed on site, whereas normally it would take up to 70 people to complete the panel installations The use of CFS eliminated 90 percent of on-site labor required by traditional construction practices The Advantages and Challenges of Modular Construction RealProjectives provides a list of the pros and cons of using modular construction for commercial applications: Advantages Saves time No possibility of weather delay No need to store materials Lower labor costs Lower volume of waste Challenges Mass production / limited variety Higher amount of complex decisions / front loaded design Approval process can be complicated Risk is on few suppliers Transportation costs & risk Difficult financing process “The benefits outweigh the detractions for most prefabrication and modular construction, but there is a balance point depending on the scope and schedule needs of individual projects,” says Snyder. “For instance, you want to have over 50 bathrooms that are the same before bathroom pods makes sense,” says Snyder. “”This scale is why you see modular construction more in health care, high-rise residential or hospitality, where you’re building the same room over and over.” Article cited from www.buildsteel.org Recent Posts Steel Framing Helps Schools See the Light Ken Simonson: Look for Growth and High Input Prices in 2022 3 Tips to Construct Greener Buildings with Steel Framing Steel Studs Make Bob Vila’s ‘Best Tips’ List Prefabrication with Steel Framing: Centuries in the Making Categories CFS Connectors CFS Software Construction Continuous Rigid Insulation Featured ISO 9001 Light Steel Framing Industry News Light Steel Framing Industry Projects Load Bearing Steel Framing New Products Training & Education TSN News Tags CFSEI Cold-Formed Steel Installation ISO 9001 Light Steel Framing Panelization Residential Wind Loads Wood vs. Steel Archives Archives Select Month December 2021 November 2021 October 2021 September 2021 August 2021 July 2021 June 2021 May 2021 April 2021 March 2021 February 2021 January 2021 December 2020 November 2020 October 2020 September 2020 August 2020 October 2019 September 2019 August 2019 July 2019 June 2019 May 2019 April 2019 March 2019 January 2019 November 2018 October 2018 September 2018 August 2018 July 2018 May 2018 April 2018 January 2018 November 2017 August 2017 July 2017 June 2017 May 2017 April 2017 December 2016 July 2011 Policies ©1995-2021 The Steel Network, Inc. - Light Steel Framing Manufacturer - Steel Studs, Track, Shear Walls, & Connectors
