Pre-Manufactured Value

Pre-Manufactured Value (PMV) is the financial proportion of a construction project’s Gross Construction Cost derived through pre-manufacturing.

Why use the PMV approach?

Pre-Manufactured Value enables organisations to adapt design, supply chain and construction choices to deliver productive, predictable, safer and higher quality homes and buildings.

PMV can be estimated using an assessment of the cost of materials and manufactured components relative to on site labour, supervision, plant, logistics and other site organisational measures.

AdaptaHaus systems offer pre-manufactured value certified at over 60%.

What is PMV?

Pre-Manufactured Value (PMV), was first set out in The Farmer Review as a metric to measure the proportion of manufactured components.

Expressed as a percentage, PMV is intended to identify the extent to which off-site techniques are implemented, aiming to reduce on-site labour. A higher PMV percentage signifies a greater proportion of off-site activity on a project, programme or portfolio.

The 2018 Industrial Strategy Construction Sector Deal explicitly commits to “measurable improvements in productivity, and the level of pre-manufactured value in buildings and infrastructure”.

The public sector has therefore embraced PMV as a proxy measure to encourage greater adoption of off-site solutions, where it affords value. However, PMV should be implemented as part of a comprehensive, outcome-focused scorecard, rather than as an isolated Key Performance Indicator (KPI). Given its origins (i.e. from a comprehensive review of the UK’s construction labour model), PMV is a key factor in a broader strategy to achieve improved social, environmental, and economic outcomes.
