    6. Install 2x6 PT sill plate on the perimeter of the foundation.

Instructions

  1. On the day of installation while the crane is setting up, install the sill plate to the perimeter of the foundation. Use the Ramset Gun to pin the sill plates to the foundation in a few places.

  2. Once the Modal arrives at the site, pull measurements off of the Modal for the bracket locations to make sure the floor joists are missed. Use these measurements to locate the brackets on the foundation, the brackets will sit behind the sill plate. Use marking paint to mark the bracket locations and drill holes for them. Once the holes are drilled, anchor the brackets to the foundation.

  3. When the truck driver pulls the chains that hold the Modal to the trailer, remove the D-rings from the Modal.

  4. Once the Modal is picked up by the crane, measurements will need to be taken of the strap locations. Based on those measurements, cut out 1’ from the sill plates centered on the strap locations. This allows the straps to be removed once the Modal is landed on the foundation and also provides ventilation to the crawl space.

  5. After the unit is landed, remove the 2x4 blocking that protects the base of the unit. Attach the screen mesh over the crawl space ventilation. To install the skirting, start at one corner, cut and bend a 90 on the left hand side of the first piece of skirting. Go counterclockwise, clicking the skirting together and attaching it with the supplied hardware.

  1. Confirm framing as-builts and install brackets prior to unit landing

  2. Secure Modal to foundation (see directions below)

  3. Install mesh/screen to cover vents for crawl space (see directions below)
