Donaldson Timber Systems<\/a> has become the first offsite timber frame manufacturer to offer a verified Pre-Manufactured Value (PMV) score of 55% or more<\/h2>\n

Leading UK offsite timber frame manufacturer, Donaldson Timber Systems (DTS), has become the first timber frame manufacturer<\/a> to achieve a minimum verified PMV score of 55% with its DTS Sigma\u00ae II build system.<\/p>\n

The build system was tested on a live project which included a 2-bed mid-terrace, a 3-bed end-terrace and a 4-bed detached home and was found to achieve a verified PMV of 55.7%, 55.8% and 58.4%, respectively, following a six-month material and labour cost analysis completed by Cast Consultancy.<\/p>\n

What is a Pre-Manufactured Value (PMV)\u00a0score?<\/h3>\n

Pre-Manufactured Value or PMV is a way of calculating the proportion of a building\u2019s construction that takes place offsite or near-site using Modern Methods of Construction (MMC)<\/a> and can be achieved through a combination of off-site, near site and on-site manufacturing techniques, as well as through materials innovation and site-based process improvement and technology.<\/p>\n

Cast Consultancy has published a PMV Technical Manual explaining how the calculations are carried out. The baseline for the calculator, building a \u2018traditional\u2019 house without any additional MMC elements, provides a PMV of just 39.74%. While adding a basic structural framing system, such as timber frame<\/a> (MMC Category 2a), raises it up to 44.74%, it still falls short of the required 55%. Setting the target of 55% is pushing the industry to innovate and to drive more offsite construction.<\/p>\n

Affordable Homes Programme requires all projects to have a calculated PMV of 55%<\/h3>\n

Homes England Affordable Homes Programme requires all projects it funds to have at least 25% of the units delivered through MMC and a calculated PMV of 55%.<\/p>\n

The verification by Cast confirms that DTS can achieve this target PMV value through the build system alone, when using the, BOPAS and BBA-approved, closed panel Sigma\u00ae II Build System.<\/p>\n

While the system can be used in conjunction with other offsite technologies to further improve PMV, Sigma\u00ae II achieves the target levels of PMV without reliance on any other off-site technologies.<\/p>\n

What are the benefits of increasing PMV?<\/h3>\n

There are numerous benefits of increasing PMV, including increased quality and performance, improved productivity, minimal waste, faster on-site delivery and reduced health and safety risk.<\/p>\n

The PMV value of Sigma\u00ae II is achieved by a combination of offsite elements of the build, including:<\/h4>\n
