Off-site or modular construction provides huge opportunities for improving the productivity and efficiency of the construction industry. Some of the most significant gains from modular construction are in waste reduction, labour costs, and schedule reduction.
Acceleration
One of the most reliable benefits of modular construction is the acceleration of the project timeframe. The McKinsey report (2019) outlines that modular construction consistently results in projects being completed 20-50% faster. Earlier completion dates allow developers and investors to generated financial gains from the project earlier.
Waste Reduction
Waste can be significantly reduced using modular construction methods. As units or components are manufactured in a factory-like setting off-site, there is a reduction in waste resulting from poor weather conditions, and standardisation can also reduce an excess of materials and a reduction of any onerous rework required.
Labour Force
While traditional construction relies on a number of specialist, skilled workers, whose training is time-intensive, modular construction can attract and develop unskilled workers, and aren't reliant on skilled tradespeople. This provides developers with a means to overcome skills shortages.
Health & Safety
By removing the majority of work from the building site, modular construction boasts health and safety benefits. Standardised, controlled manufacturing removes the hazards resulting from onsite construction while protecting against seasonal dangers.
Sustainability & Environmentally Friendly
Modular construction can provide a more sustainable alternative to traditional builds. Offsite construction can reduce waste by up to 90%, and usually use less energy in their production (up to 67%). Furthermore, modular buildings can be produced using recycled materials, and can themselves be reusable.
