Modular Systems
Agreed Specification
Manufactured under factory conditions
Reduced waste
Comparison of main contractors on similar sites
and shared experience
Advantages
Reduced labour
Reduced vandalism during site operations
Early Completion
Optional façade treatment
Reduced architectural / design costs
Consistency across all units
4
Modular System
Nominal site tolerances
Changes to design limited once fabrication and
installation underway
Limitations of structural grid system on unit
design
Material sustainability limited compared to
timber framed solutions
Access requirements to site (positioning)
Disadvantages
Geographic distance between supply
manufacturer/installer and site
Limitation of structural system for future
alterations
Co-ordination of interface between main
contractor and modular installer
Installation maintenance of concealed services
