MG McGrath has applied many of the same principles behind unitization to modular construction. While the two types are similar, the main differences are the installation methods and connection style. Compared to traditional field-built structures, modular construction can often be faster, safer, and just all-around better quality.

At MG McGrath, we have a dedicated assembly facility specifically geared towards the production of our modular facades with skilled craft workers at each station. We combine the ingenuity of mass production with the quality, skill, and passion of our custom fabrication. Whether you want us to supply-only or to supply and install, we are set up to accommodate your modular project needs.



Modular facades are designed, engineered, and fabricated to extremely precise specifications that include framing, insulation, weather barrier, air barrier, vapor barrier, and exterior metals+ paneling and/or glass+. These façade units are then installed onto the pod/module in a controlled shop environment. The pod/module is then transported to the jobsite where it is lifted and installed on the building as a whole unit. Our unique gasket system on the outer perimeter of the modular façade units ensures an air and watertight enclosure as each module is installed on the building.



For volumetric modular facade construction, early involvement and coordination is not just preferred, but required. There is more up-front time spent on preconstruction and design assist, but the tradeoffs are well worth it. Because everything is so precise and heavily engineered on the front end, the execution and construction portion of the project typically moves very fast. And since the majority of the fabrication and installation work is done in a closed, controlled facility, safety and quality go way up. The ease, accessibility, and predictability of a shop environment cuts down on delays, safety risk, and allows for more oversight on quality as a project moves through its lifecycle.
