Some of the advantages of offsite construction are:
- Construction can begin while foundation work is done, reducing the overall build time by several weeks.
- Because building is done indoors in a climate-controlled facility, there are no weather delays. Crews can work year round with no problem.
- The building is built dry and clean because the wood is not subjected to dampness or dirt. This could make for a healthier building.
- Greater accuracy in cutting is possible because precision equipment can be utilized.
- Lower costs because of consistency with crews and minimal lost time. An off-site built building can cost up to 15-20 percent less than the same built on-site. Savings for commercial construction can be much higher.
- Very low waste. Just about all remnants can be re-used for other projects. This enables contractors to purchase more wisely.
- The building envelope is fully customizable, enabling increased energy efficiency in the wall and ceiling systems, as well as design features that meet the needs of the occupants.
- Modular building, especially in commercial, enables easy expansion to buildings when needed.
Although off-site construction currently accounts for only two percent of construction in the U.S., the industry is gaining popularity. In Europe, especially countries like Sweden, this type of construction is on the rise and accounts for up to 40 percent of new construction.
If you are considering building, do a cost comparison for on-site versus off-site construction. You may be surprised by what you find.
