The installation of modular buildings requires adherence to a defined process encompassing delivery, site preparation, permitting, and utility connections. These structures are designed to meet federal, state, and local building codes, often referencing the International Building Code (IBC). Successful installation relies on careful planning, compliance with regulations, and the expertise of registered installers. This article details the key stages involved in modular building installation, based on available documentation.
Delivery and Initial Inspection
Upon delivery, a thorough inspection of all components is crucial. The documentation emphasizes verifying the number of boxes and inspecting them for any damage. Any discrepancies or damage must be noted on the delivery receipt. Customer service contact information (800-728-5454) is provided for reporting issues. Once packaging is removed, all panels should be inspected before installation begins.
Understanding Panel Labeling and Components
Modular building kits utilize a labeling system to facilitate assembly. Each panel is marked with a number corresponding to a “plan view” included in the installation package. Floor panels are designated with an “F,” wall panels with a “W,” and ceiling panels with a “C.” The documentation notes that the arrow on wall panels points downwards, and cam lock holes are located on the inside of the panels. A cam lock wrench is included in the installation package for securing the panels.
Site Development and Foundation Systems
Proper site development is a prerequisite for modular building installation. The selection of an appropriate foundation system depends on several factors, including local building codes, the intended duration of the building’s placement, budgetary constraints, soil composition, and environmental conditions such as susceptibility to high winds, flooding, frost, or seismic activity. Two common foundation systems are acrylonitrile butadiene styrene (ABS) pads and concrete pier foundations.
Permitting and Regulatory Compliance
Obtaining the necessary permits is a standard part of the modular building installation process. Applicants must comply with federal, state, and local regulations. Documentation, including floor plans, plumbing plans, wiring plans, and structural calculations, is required for permit applications. Working with an experienced modular building provider can streamline this process. Local regulations may vary, with some municipalities allowing temporary structures while others have specific appearance requirements. Colorado regulations stipulate that local standards cannot be less stringent than those set by the Division of Housing and require consent from the Division for differing standards, except for unique public safety requirements related to geographic or climatic conditions.
Modular Building Delivery Process
Modular buildings are delivered to the construction site as separate modules. Delivery is typically conducted by a fleet of trucks with protective coverings to shield the modules from damage during transit. Adequate vertical and horizontal clearance must be ensured for truck access and module offloading.
Installation and Assembly
Once delivered, qualified contractors connect the modules and install them on the prepared foundation. This ensures safe installation and compliance with local regulations, regardless of whether the building is intended as a temporary or permanent structure. Accessory installation, such as skirting, canopies, awnings, custom roof lines, ramps, and stairs, is also performed during this stage.
Utility Connections
While modular buildings are often completed offsite with fixtures and interior finishes, they require connections to external utilities. This includes connecting to a power source and hooking up to sewer and water lines.
Registration and Certification of Installers
In Colorado, all manufactured homes, including multifamily units, must bear a certificate of installation from the Division of Housing, confirming compliance with approved installation manuals. Installers must register with the Division of Housing prior to commencing work and display the completed Installation Authorization form on the structure until certification is achieved. A list of registered and certified installers is available through the Office of Regulatory Oversight-Account Search.
Foundation Plan Submission and Approval
Foundation plans require approval from either the local jurisdiction’s building department or the Division of Housing, depending on whether the jurisdiction has a building department. All foundation plans must meet minimum requirements outlined in CCR 1302-14 for both permanent and temporary installations. Plans must be submitted to the local authority for approval or, in jurisdictions without a building department, to the MHIP Program Coordinator at [email protected].
Inspection Scheduling
The documentation does not provide details on the inspection scheduling process itself, only that inspections are a necessary component of the installation process.
Conclusion
Modular building installation is a multi-faceted process requiring careful attention to detail, regulatory compliance, and the expertise of qualified professionals. From initial delivery and inspection to foundation preparation, permitting, assembly, and utility connections, each stage plays a critical role in ensuring a safe, compliant, and functional structure. Adherence to local building codes and the standards set by governing bodies like the Division of Housing are paramount for successful project completion.
