10 76 Current Practices and Future Potential in Modern Methods of Construction Introduction, Objectives, Methodology and Summary Introduction The overall objective of the research is to develop a detailed assessment of the current level of use of Modern Methods of Construction (MMC) and market size in different Construction sectors, identifying positive and negative factors influencing take-up. The focus of the project is on developing a scoping document reviewing key products, markets etc, and the emphasis is on informing WRAP s work in waste minimisation and identifying markets where significant gains can be made.
