Modern Methods of Construction – What You Need to Know

Often referred to as ‘MMC’ or ‘Smart Construction’, modern methods of construction break away from the traditional ‘bricks and mortar’ style of construction, with new methods being continually introduced and developed. It has been described as ‘a way of producing more, better quality homes in less time.’ A common trait of MMC includes off site, factory production of the component parts of properties, therefore speeding up delivery, improving quality and reducing both waste and the cost of labour.
These alternative construction practices sustainably and efficiently meet the ever-increasing needs of the 21st century; it is becoming a popular choice when it comes to the construction of social housing. The process was initially created after the second world war to meet the urgent demand for residential buildings and became popular once again when the 2005 housing crisis hit.
Examples of modern methods of construction include:

• 3D volumetric (also commonly known as modular) construction is where units are produced in a controlled environment, for example a factory, before they are transported to site.
• Timber Frames – this method of construction uses renewable materials and encourages flexibility regarding the building’s layout and appearance.
• Flat Slabs – This method removes the need for beams, offers flexibility in layout and speeds up the construction process.
• Concrete walls and floors.
• Precast panels and foundations – These are made off-site, offering speed, accuracy, and quality.
• Twin wall technology –This is used to join and reinforce two pre-made walls.
• Thin joint masonry – Allows for a thinner depth of mortar enabling faster laying.

The National Audit Office (NAO) stated that if the more traditional methods of construction were replaced by modern methods of construction, it would be possible to build 4 times as many homes with the same amount of on-site labour. However, on the contrary, cost ranges would be higher on average with increased risks at the initial stages of the development process.
