Modular construction is not the same as prefabrication. While both pre-fab and modular components are built off-site, pre-fab components are usually the result of a one type of contractor (e.g. framing) while modular components come as complete systems (e.g. structure, wiring, plumbing, HVAC, etc.).
Modular construction requires multiple skillsets such as mechanical, electrical, plumbing contracting along with structural fabrication. Three-dimensional modeling such as Building Information Modeling (BIM) is the technology that enables modular construction. BIM allows critical mating surfaces between modules to be located with a very high degree of precision.
We design modules for use in projects and produce those modules in our own facilities for commercial buildings as well as for industrial and power plants.
Our experience with modular construction has proven that it provides many advantages compared to building on-site:
- Reduced cost
- Easier labor management and higher productivity
- Better project quality
- Minimizing space requirements and materials
- Shorter construction time
- Safer construction
Projects where substantial portions of the build are standardized and repeatable make some of the best modular construction opportunities. In addition to other advantages, modular construction of MEP systems reduces the space needed for ductwork and helps keep piping and ductwork cleaner for sensitive processes.
Examples of common modular construction include:
Skid-mounted equipment – Skids containing, for example, heat exchangers, pumps, air compressors, condensers, vacuum equipment and process systems with supporting frames, interconnecting piping and electrical power and controls.
Bathroom pods – Bathrooms with HVAC, lighting, plumbing and fixtures tend to be very standardized and thus good candidates for modular construction.
Overhead mechanical racks – Long runs of customized design containing mechanical piping, cable trays, ductwork, electrical & lighting conduit and pneumatic tubing.
