Modular construction may also provide an advantage in similar categories from the International Green Construction Code.
Ability to service remote locations. Especially in countries in which potential markets may be located far from industrial facilities, such as Australia, there can be much higher costs to construct a site-built house in a remote area or a place experiencing a building boom like mining cities. Modular buildings are also beneficial in providing medical and sanitary facilities where time, space, and money are an issue.
Flexibility. One can continually add to your modular construction, including creating high rises. When the demands alter, modular buildings can be disassembled and the modules relocated or refurbished for their next usage reducing the demand for raw materials and minimizing the amount of energy expended to make a building to meet the new demand. Essentially, the entire building can be recycled in some cases.
Modular buildings have been argued to have advantages over traditional buildings, for many different factors.
Low waste. With the same programs being continuously built, the producer has records of exactly what amount of substances are necessary for a given job. Together with the consistency, builders can design systems that use common lengths of timber, wallboard, etc.. cut things with maximum efficacy, or be able to order exceptional lengths in bulk. While squander from a site-built dwelling may typically fill several big dumpsters, building of a modular house creates much less waste. According to the UK group WRAP, up to a 90% decrease in substances can be accomplished via using modular construction.
Quality. Combining traditional building methods, quality manufacturing and third-party agencies who offer arbitrary inspections, testing, and certification services for quality management, commercial modular structures are made in strict compliance with appropriate local, state, and national rules and regulations. Due to the requirement to transport modules to the last website, each module must be constructed to independently withstand traveling and setup requirements. Thus the final module-to-module meeting of independently durable components can yield a final product that is stronger than site-built structures. Modular buildings often utilize Structural Insulated Panels (SIPs) in construction, which provide a range of benefits over traditional construction materials. They are air-tight, and as such provide exceptional thermal performance. They also offer exceptional damp and cold resistance when compared to timber and other substances, and are immune to both compression shrinking and cold bridging.  Modular units might also be designed to match in with external aesthetics of any existing construction and modular units once assembled can be virtually indistinguishable from a site-built structure.
Modular construction allows for the construction and the site work to be completed concurrently. According to some substances, this can reduce the overall completion schedule by as much as 50%. This also reduces labour, financing and supervision expenses. To save time and money, nearly all design and engineering disciplines are a part of the manufacturing process. During site-built construction, walls cannot be placed until flooring are set up, and ceilings and rafters can't be added until walls are erected. On the other hand, with modular structure, walls, flooring, ceilings, and rafters are all constructed at precisely the exact same time, and then brought together at the same factory to form a construction. This process can enable modular building times of half that of traditional, stick-built structure.
Environmentally friendly building process. The controlled environment of the factory allows for more accurate construction while permitting the additional stuff to be recycled in house. 
Indoor construction. Construction is independent of weather, which may increase work efficiency and averts damaged construction material.
Improved Air Quality - A lot of the indoor air quality issues identified in new construction result from high moisture levels in the farming materials. Because the modular construction is substantially completed in a factory-controlled setting using abrasive materials, the prospect of elevated levels of moisture being trapped in the new structure is removed.
