MODERN METHODS

OF CONSTRUCTION

MMC stands for Modern Methods of Construction, which

refers to offsite manufacturing and onsite techniques that

offer alternative construction methodologies to traditional

building methods.

MMC can deliver faster project delivery times, higher levels of quality, and improved

construction sustainability. C+W O’Brien Architects incorporates a Design for Manufacture

and Assembly (DfMA) philosophy into our design approach, which maximises the efficiency of

materials and systems. We have extensive knowledge and expertise in all forms of MMC and

have visited manufacturing facilities in Ireland, the UK, Europe and China to assess

capabilities and quality control standards.

C+W O’Brien Architects are actively leading the construction industry transition to greater

levels of MMC adoption through their participation in various national committees. The

architects believe that modular construction can be a faster and more efficient way to

deliver construction projects, and they are eager to increase this type of construction

to avail of the many benefits it offers.

OUR SERVICES:

BIM

C+W O’Brien Architects focuses on providing added

value to clients by considering the efficiency of

project delivery both digitally and on-site in addition

to the design and quality of physical assets.

We use BIM to develop Information Requirements (IR) and a BIM Execution Plan (BEP)

that outlines the roles and responsibilities of each design team member. The team

conducts BIM coordination meetings and uses Navisworks for clash detection. The

Building Information Model is populated with data and COBie data drops are used to

create an Excel spreadsheet for analysis and checking.

NBS Chorus is used for specification preparation and a BIM Content Library is

developed to align with the NBS National BIM Library. The space and asset information

can be linked to an external database to provide efficient output of room data sheets

and equipment per room/department.

Finally, BIM allows for testing of options in terms of their likely lifecycle implications, and

early engagement of FM teams is crucial in developing an information handover strategy.
