From contract to occupancy, a modular development can take up to 60% less time than traditional build. On average 6-8 modules can be delivered to site and fixed into position each day. As the modules have been manufactured in a factory, build time and scheduling are not affected by poor weather conditions. Such time savings have a positive impact on financial returns and profitability.
Through well thought-out template design, we have greater cost certainty, avoiding un-planned, additional material or labour costs. This also leads to considerable economies of scale in production, without the needs of preliminary costs (e.g. site cabins, machinery hire etc).
A factory environment ensures quality assurance is tested not only to withstand the demands of a traditional build, but also the stress of transportation and craning onto foundations. Each component is inspected at every phase and approved by third-party inspectors, complying with precise specifications and codes.
When building in a factory, waste is eliminated by recycling materials, controlling inventory and protecting building materials. Because the modular structure is substantially completed in a factory-controlled setting using dry materials, the potential for high levels of moisture being trapped in the new construction is eliminated.
?Building Information Modelling (BIM) is used in design and programme planning. Harnessing BIM Level 2 enables modular homes to achieve optimum energy efficiency through intelligent virtual design, team collaboration, enhanced manufacturing and site installation methodologies. Many modular manufacturers and contractors in the UK adhere to the ethos of Building Research Establishment Environmental Assessments Methodology (BREEAM), producing buildings that boast the utmost energy efficiency. Modular units are thermally very efficient reducing energy use and CO2 emissions.
Less time on site also means less disruption to the local community. Removing approximately 80% of the building construction activity from the site location significantly reduces site disruption, noise, vehicular traffic and improves overall safety and security.
The Housing White Paper ‘Fixing our broken housing market’ (February 2017) states that not enough homes are being built and in order to solve the housing shortage (built up over many decades), a radical re-think of our whole approach to home building is required. As part of that ‘re-think’, the document states that one of its aims is to diversify the housing market by seeking to ‘promote more modular and factory built homes’. ??
