Pre-manufactured value
Pre-manufactured value (PMV) is a measure of the extent of offsite construction used on a project.
A project that is predominantly of traditional construction will have a low PMV, whereas a modular construction project would be likely to have a high PMV.
PMV can be calculated based on aspects of the project such as quantity of material manufactured offsite, percentage by volume of precast components and so on. The Department for Education defines PMV as (materials + offsite labour) / (materials + offsite labour + on site labour). Quantitative approaches such as this require that data is available in a suitable format and in sufficient detail to allow comprehensive calculations to be undertaken.
Alternatively a more qualitative approach can be adopted, describing PMV as high, medium or low.
