17 Generic Advantages of MMC Rapid speed of construction Reliable quality control Reduced reliance on traditional skills Competitive economics High quality design and detailing Excellent environmental credentials. Modern Methods of Construction

18 Selected Trends in MMC Use of modules and panels to give hybrid solutions Use of long span floors to give adaptable internal space Building heights of up to 10 stories Efficient light steel structures that allow for a wide range of geometries and architectural treatments New methods of accommodating services. Light foundation systems Modern Methods of Construction

19 General Environmental Benefits Exceptionally efficient use of material Minimal wastage Long service life High recycling rates Reliable thermal and acoustic performance New foundation systems reduce ground contamination Modern Methods of Construction

20 Environmental Benefits: Building Design Opportunities for detailed building physics appraisal and testing Efficient pre-engineered service systems easily incorporated High correlation between theoretical and actual thermal and acoustic performance Varying levels of acoustic and thermal insulation possible, and high performance standards easily achieved. Modern Methods of Construction

21 Environmental Benefits: Construction Site installation is rapid and quiet Units can be delivered sequentially just in time Total number of deliveries to site is much reduced Site waste is reduced by approximately 30% Relatively light foundation systems can usually be used Modern Methods of Construction

22 Environmental Benefits: In Use Good thermal insulation reduces energy needs and improves occupant comfort. Good acoustic insulation avoids excessive noise transfer between dwelling or between dwellings and communal areas. Modern modular buildings are easily adapted and reconfigured Modern Methods of Construction

23 Environmental Benefits: Re-use Demolition is straightforward Materials can be easily recycled Modules can be reused Light foundations are relatively simple to remove Modern Methods of Construction
