MMC Calculator

AS A PIONEERING INNOVATION to social value investment, modern methods of construction (MMC) experts Akerlof, announce their partnership with specialists Social Profit Calculator, consultant Rider Levitt Bucknall, framework leaders Pagabo and the UK’s largest regional contractor Kier, to develop a social value calculator dedicated to MMC.

As the construction industry continues to wrestle with the  ‘productivity challenge’ at a macro scale, the Government has sought to shift its focus from boosting national economic growth towards improving wellbeing in poorer areas and narrowing productivity gaps regionally.  Data analysis shows regional imbalances, with disparity in employment, investment and quality of life. To address this, the new catchphrase in Prime Minister Boris Johnson’s government is ‘levelling up’ – raising the economic performance in all parts of the UK.

By using MMC – adopting manufactured solutions and extending the construction process beyond the confines of the site hoarding – we bring investment to deprived areas and sustainable jobs to their communities. The Government recognises this, reinforcing its ‘presumption in favour of’ offsite through the appointment of Mark Farmer, CEO of Cast Consultancy, as ‘champion of MMC in housebuilding’. Mark is “charged with developing the ‘construction corridor’ in the North,” starting with £30m Homes England investment to the area, announced pre-Christmas.

MMC comes with significant benefits, but recent research has shown that just 7% of UK construction is currently undertaken in this way. By increasing this proportion to 25%, the WPI Economics report for Heathrow shows that productivity in the sector could increase by 3.6% with much of this growth coming in areas of the country that would most welcome it.

The report also concludes that significant expertise and experience of offsite manufacture currently sits outside of the capital and, coupled with lower land and labour costs, this means that increased offsite manufacture will provide significant economic benefits to regions outside of the major cities and particularly London. Modelling in this report shows that, by boosting employment and utilising skills and expertise outside of the Capital spur to growth outside of London could be worth some £15 billion.

Our map below illustrates the location of offsite manufacturing facilities mapped against areas of deprivation. It demonstrates how an increase in MMC provides the opportunity to address construction skills shortages in London and the South East by moving activities from these regions and creating sustainable employment in other parts of the UK


Our Modern Methods Social Value Calculator enables the assessment and visualisation of social value to identify the holistic impact of construction, not just on site, but also at manufacturing locations through the supply chain.

Whilst the promise of ‘levelling up’ sounds attractive, the ability to import holistic economic considerations into a ‘Procuring for Value’ agenda at a project level remains a challenge. Our calculator looks to addresses this hurdle. Underpinned by industry and Office of National Statistics data, it enables the evaluation of MMC options on a broader basis than direct capital cost; quantifying the benefit of the social value investment and productivity-enhancing potential.

At Akerlof, we care about how the built environment shapes society. Applying our skills to enable, support and deliver balanced social-economical enrichment is aligned with our purpose. Alongside our partners, we are proud to launch the MMC calculator in encouraging the adoption of offsite manufacture and modern methods in supporting a regionally-balanced industry that delivers a fairer, better, more sustainable society.

With a penchant for tweed and jackets with leather arm patches, Jamie began his career as a quantity surveyor, before climbing the ladder to lead major projects for a Tier 1 contractor.

Eventually expanding his book collection beyond copies of SMM7, Jamie has interest in a broad range of subjects linked to delivering better outcomes for society and the environment.

His strategic insights on MMC and behavioural science have made their way into numerous government, industry and academic publications, including the Construction Playbook, Transforming Infrastructure Performance Roadmap to 2030, the Platform Rulebook and the RIBA DfMA Overlay.

John Handscomb


Construction is in John’s blood. Learning from his father who was a planner and project manager, John began his career by working on some iconic projects in both the public and private sector.

As a procurement expert and integrator of new ways of working, John has pioneered the integration of platform principles, DfMA processes and supply chain within over £5bn projects in the last 15 years, for some of the largest building programmes in the UK. Despite his considerable expertise, John keeps it simple, communicating complicated ideas with ease and helping to equip the industry with new knowledge and skills.

Outside of Akerlof, John enjoys his executive role with technology start-up ScanTech Digital, spending time with his family, taking trips down the football, playing a bit of golf with friends and the odd pint. 

Our name is shared with George Akerlof, a Nobel Prize-winning economist.

His seminal paper, Market for Lemons, demonstrated the devastating consequences of making decisions under the conditions of quality uncertainty and unequal information between buyers and sellers, increasing the chance of buyers ending up with a ‘lemon’.

This 50-year-old concept continues to retain parallels within the construction industry.

Through our insight and experience, we can rebalance this information asymmetry on behalf of our clients, levelling the playing field to deliver better outcomes.
