Installation and Completion Phase
After we have finished building your project in our factory and it has been inspected, we deliver it to your site where it is installed on the foundation and other subcontractors complete it.
Delivery of Your Project
For most projects, we hire the professional home transportation company whose specialized equipment and trained dispatchers and drivers will get the modules of your project from our factory to your home site. When the delivery of the project is in our scope-of-work, we take responsibility for the modules until they arrive at your site. Your builder’s risk insurance then takes over.
Some general contractors have their own specialized transportation equipment or preferred transportation company. When the delivery of the project is in your scope-of-work, you take responsibility for the modules from the time each is attached to a truck at our plant.
For some projects which will be placed in a densely developed area it may be necessary for your project to be delivered to a suitable nearby “marshaling yard,” from which the modules can be shuttled to your building site in the proper sequence and as they are needed.
Installation of the Modules on the Foundation
We work with you to synchronize the delivery of the modules with their installation on the foundation. The goal is to minimize the risk of damage or even theft.
Structures with a permanent transportation chasses to be installed on a simple pier foundation, may be simply pulled into position, the piers completed and shimmed to get the modules level, and the modules fastened to each other in accordance with the plans and our installation instructions.
One story structures with a permanent transportation chasses or delivered on returnable carriers may be installed on a crawl space or basement foundation using a system of rails and rollers. The modules are positioned beside the foundation, and then rolled onto the foundation. The modules are then fastened to the foundation and to each other in accordance with the plans and our installation instructions.
For multi-story structures and for most one-story structures delivered on returnable carriers, a crane is used to lift the modules off of the returnable carriers and placed on the foundation. Many of our projects have hinged roof systems, accommodating higher roof pitches than can be transported within typical height limitations. Hinged roof systems will usually also entail a series of framed assemblies forming the peak, which must be installed, sheathed and shingled on the site. The crane may be used to lift the hinged roof sections and the ridge assemblies. Alternatively, the installation crew may use jacks and smaller booms to complete the roof. Another use of the crane is to lift any dormers into position on the roof.
A milestone in the installation process is the “weathering in” of the project, meaning the installation of the modules on the foundation and the completion of the roof and covering of any openings so that the interior of the home is safe from rain, snow and wind. The work up to this point is referred to as the “rough set.” Some general contractors have the capability of performing the rough set with their own staff. Alternatively, you may also contract with a company that specializes in rough sets. In the US, you can also contract with us to have our crews perform the rough set. In fact, on some complicated projects, we may require that you use one of our crews. For complicated projects in Canada, we may recommend that you arrange for one our experts to be present during rough set.
Activities of Other Sub-Contractors
With the completion of the rough set, other local sub-contractors can carry on with their work. At a minimum, this will include the following tasks:
- For structures with more than one module, the siding, interior drywall and paint work, any prefinished interior paneling and interior and exterior moldings and trim at the mating line must be installed.
- Water, drain and vent piping between modules must be connected and then connected to the municipal or private water source and sewer or septic systems.
- Repairs to minor and commonly occurring transportation and rough-set damage such as repair to drywall stress cracks and re-adjustment to doors and windows that have shifted out of plumb-and-square positions.
- Heating and cooling ducts and/or fuel lines must be connected.
- Electrical and communication wiring between modules must be connected and then run to the power and communications grids.
- Concrete flat work such as walks and driveways.
- Final landscaping.
Other work that may be completed by your local subcontractors may include:
- Installation of a hot water heater and any water softening or purifying equipment, especially if they are to be located in a basement.
- Installation of the heating, cooling and ventilating systems, especially if they are to be located in a basement.
- Framing and finishing of miscellaneous structures, such as porches, garages, storage buildings, decks, pools and cabanas.
- Custom millwork, doors, windows, flooring, cabinetry, plumbing fixtures, light fixtures and other items available from us, but purchased elsewhere and installed on-site.
- Finish painting and decorating.
- Appliances available from us, but purchased elsewhere and installed on-site.
- Sprinkler systems.
The inspection of your project in our plant applies only to our scope-of-work. Most work done on site must be inspected by your local building inspector, especially the foundation, plumbing, heating, ventilating and electrical connections, and the structural soundness of those miscellaneous structures framed by others at your site
