8 Key Players in the Modular Building Process

There are many key players involved throughout the modular process

When you are at the beginning stages or deciding which direction to take in the modular building process, you will want to know all of the key players to help make your journey easier and more efficient.


ClientClients are the people who purchase (and many times occupy) the finished building. The client's knowledge of modular construction, may widely vary. Whether the client wants to actively participate on the entire process or dictate the process themselves, or they would like to be carefully led through each step of the process; most clients have similar concerns. Concerns shared by all clients include budget limitations, schedule deadlines and desire for maximum value for their investment. IMS will help identify and address all of these concerns and needs from the very first contact.  




The additional element brought about by building offsite is that most localities require a third party to help regulate the design approval and inspection of the building at both the manufacturing plant and construction site.  The building code official enforces the building codes. These codes are assemblies of industry standards and specifications that are created (1) to establish safeguards in design and construction of the buildings, (2) to protect people who use the building from fire and other hazards, and (3) to further protect the health and safety of the public. 



EngineeringThe design professional designs the project to the client's needs and specifications. Design professionals can consist of architects, building manufacturers and engineers including; structural, mechanical and electrical as well as others as required. Design professionals ensure that the designs remain consistent with the client's needs, specified products, and systems and building codes. The prepare detailed plans, specifications and preliminary cost estimates. 



Authorized-DealerDealers influence the quality, content and timeliness of project communications more than any other key player. Dealers make initial contact with end-users and serve as the client's window  to the entire building process. Dealers help clients define and assign project responsibilities. They present the overall building and site project costs to the client utilizing quotes from various subcontractors. The dealer's role in the construction process depends on the type of contract, project scope and level of client involvement. 



Construction-ManagementManufacturers are classified in two categories depending on their role in the modular building process. One category is "wholesaler" and the second is "Direct". The wholesaler sells exclusively to the modular dealer while the direct manufacturer sells to clients (some sell to dealers as well).  Communication and cooperation between manufacturer and dealer must be continually refined and enhanced to ensure successful project outcomes.




Vendors supply the raw materials and services for the entire industry. Vendors source and develop products to meet the unique challenges inherent in the modular building industry. 

Beyond raw material suppliers, vendors provide many additional services including building design and approvals, financial services, module transportation, equipment and tools and supplies and software.


INSTALLERS (set-up crews)

Installer-1Installers erect the individual modules shipped from the manufacturer into the finished building. Moving and lifting heavy building modules carries risk of accident and injuries. Safety regulations are required for safe working practices.

The installer often has direct contact with the client on the job-site. The client's satisfaction with the modular building experience relies on the conduct and commitment by the installers on the entire project. Typical of all modular building key players, efficient completion of their scope of work is critical for installers. 



 In the modular building industry, there is increased subcontractor involvement in projects. Systems such as fire sprinklers and alarms must be designed and installed by licensed professionals. 


The general contractor ensures that safety practices are adhered to and deadlines are met. The general contractor also coordinates and manages the various trades to complete the building such as plumbing, electrical, masonry and mechanical. Manufacturers and dealers can expand their markets through the effective use of subcontractors.
