Modular housing decreases construction time almost to half and the overall expenses by 10 to 20 percent. A small crew of moderately skilled workers can deliver the construction task in a climate-controlled installation rather than utilizing about 22 separate trades of professions that contribute to conventional home construction, using the same building codes and standards. These structures are manufactured in modules or small parts, which are delivered and mounted at the final construction site. Modular construction is gaining popularity as a potential answer to housing shortage and soaring housing and construction expenses. There are two main branches in this trade; Permanent versus Relocatable Buildings.
Benefits of Modular Housing
Modular construction is a sustainable, efficient and innovative technique to think about while planning to start a building project. Like in any building project, effective construction administration is critical to realize favorable results.
Modular housing can be completed 30-50% times faster since building manufacturing can proceed concurrently with the site and foundation work.
Elimination of Weather Delays
A major factor in project delay is the weather. The weather influence can be greatly omitted due to the fact that 60-90% of the manufacturing is completed in a closed workshop environment.
Off-site building allows for more GC management and control on correctly following quality and safety guidelines. In many cases, it is much easier to inspect the material and workmanship in the workshop as a job is in the process than making the inspections on the construction site.
Many modular buildings can be dismantled and erected in a new location for new purposes, a great conservation strategy for raw materials and energy. Even in Permanent Modular facilities most of the materials and modules can be recycled with much ease and much smaller portion of the material is disposed of as scrap and debris.
The factory facility provides for safer working space avoiding hazards present in construction sites and eliminating many risk factors. Modular housing decreases the amount of work time in heights and dangerous situations.
Modular buildings benefit from a much stronger structure since each module has to withstand transportation and lifting impacts. Assembled modules result in a much stronger structure than conventional buildings.
Since approximately 80% of the job is done offsite, modular construction allows business owners to continue working while renovations are being done. Modular construction also reduced disruption for the buildings surrounding the project site.
In most cases utilizing innovative environmental-friendly material is much more practical and feasible in a factory environment. A wider range of materials becomes available when the construction process can be completed under controlled factory conditions.
Affordability is a key feature of modular construction. When multiple similar pieces are being made all at once, cost and time savings are achieved with economies of scale. Modular housing creates more return on investment in developments with many similarly designed buildings are constructed.
Modules are manufactured as separate units, with proper workmanship they are assembled with soundproof features.
Drawbacks of Modular Housing
One major issue for modular housing is the proper delivery and transportation of the modular building parts. The size and properties of each element must be considered, to determine a transportation method that will not cause damage. The transportation and road constraints impose some size limitations on the room and building sizes.
When financing modular homes, banks will normally issue a loan that goes through two stages. These are known as construction-to-permanent loans. In many cases, owners cannot get a traditional bank loan until construction on the home is complete. In these situations, a serious challenge is to get loans and funding in advance.
In some counties or towns, local authorities do not permit modular homes thus this is very important to study local regulations before selecting to follow through the modular solution.
