Cabin Site Preparation
Your cabin or home will arrive at your location as one or more pre-assembled modules. Each module is typically very large and there must be adequate room for the modules and the truck. The machinery used is custom-built and very maneuverable. It is rare that a building cannot reach its intended location after some trimming of trees, but there are limits. A Cozy Cabins representative will check your job site prior to delivery to make sure the site is indeed accessible.
Your driveway must be stoned in and/or free of all mud/sogginess at the time of delivery. Make sure straight sections of your driveway are clear at least 2’ wider than the width of the modules and at least 14’ high. Turns in the access driveway must provide sufficient space to maneuver.
For buildings going on a crawl space foundation or full basement an area approximately 40 feet by 40 feet must be provided next to the foundation for the crane to set up. This area must be completely clear overhead, including tree limbs and power lines, and must be on a decently level grade.
Smaller cabins which are going on a crushed stone pad or concrete slab are delivered with a special-built trailer similar to a rollback. The driver backs his trailer onto the prepared pad, and then tilts his trailer until the rear of the cabin rests on the pad. He then drives out from underneath the cabin. There must be adequate room in front of the cabin for him to pull straight away. This clear distance varies with the length of the building (approx. 80’-150’) and will vary with each job site.
Crawl Space / Basement
Our affordable modular log homes and cabins are typically installed on a crawl space foundation or full basement. This portion of the project is completed using the local contractor you choose. When you are satisfied with your design and are ready to proceed with the order we will provide you with a detailed foundation design, showing the size of the foundation required, as well as placement of piers & columns. This information provides your foundation contractor the all important dimensions he needs to create a final design and satisfactory footing and foundation system for your new cabin or home.
When our crew arrives to install and complete your cabin they will expect the foundation to be complete, with girders and sill plates already installed. For full basements, typically use a central steel I-beam to keep the amount of needed support columns to a minimum. This will also need to be in place before the big day. The installation crew will use a crane to lift your house modules onto the foundation. They will then fasten the modules together, and secure them to your sill plates.
Gravel Pad or Concrete Slab
Our small cabins for sale (up to 15′ wide) can go on a gravel pad or concrete slab if they are not being used for residential living. (Residential codes require a permanent foundation.) The cabin’s floor system is then built with 4×4 pressure treated skids which distribute the weight of the structure across the pad.
When creating a gravel pad the area must be leveled and graded so no run-off water will go under the cabin. Put down 4” to 6” of gravel – about 1’ longer and wider than the actual size of the cabin. Use ‘2A modified’ gravel, or a similar product that packs well. Clean driveway gravel does not pack well enough to support the weight evenly. Level your pad using a laser or other reliable method to ensure accuracy. Pack the pad using a roller or plate tamper, then re-check the pad for level. Add more gravel as needed and pack the pad again.
For a concrete slab use 4” to 5” of reinforced concrete on top of a bed of clean gravel about 4” thick. It is very important that the slab is level, as a low corner can create issues with the operation of doors, etc. Use a laser or some other reliable leveling method when finishing the concrete.
If your cabin has plumbing installed you will need an access pit. This pit allows your sewer and water to come in below frost level and gives you easy access to make the connections to the underside of your cabin after it is in place. It is typically 3’ wide and 6’ long, with about half of the length under the cabin. Ask a representative for details. The location of this pit varies with every floor plan, but is generally near the bathroom area.
