Your metal building’s strength lies in the foundation, and hence, having the right foundation is imperative. Not only can the use of the wrong foundation strategy be costly to you in the long run, but it can also compromise the safety and structure of the entire building. One of the first steps in planning for your metal building is to hire a contractor that can build the foundation.
Metal buildings are massive structures and require a stable foundation. You and your contractor will need to assess the soil’s condition, potential frosts, and the building’s overall weight. Going through the permit process and reviewing your local construction codes’ requirements can help ensure that your contractor pours your foundation right the first time.
Don’t Skip the Permit Process!
The process used for metal building installation will vary significantly based on local building codes. Most cities and municipalities require that an installation permit be pulled before pouring the foundation and before installing the steel building. The primary purpose of the permit is to ensure that the project follows zoning and building codes.
Builders that follow the permit process and abide by local building codes can ensure that the foundation is solid. Further, it ensures the metal building is safe and installed using dependable building standards.
What to Consider When Mounting Your Concrete Slab?
Metal buildings are anchored either directly to the earth or a concrete slab or footing. The area where the building will be installed is also essential to consider. For example, consider if the building is installed in cold geography; in this case, the concrete footings should be dug and secured much deeper. Be sure to check with your local building authorities to get specific information on the area’s requirements.
When preparing to mount your concrete slabs, there are three important considerations.
- Slab sizing – Your slab should be constructed to be the same width as your building but should be two inches longer. If your building is 15′ wide x 25′ long, then your slab should be 15′ wide by 25′ 2′ in length.
- Slab thickness – Your concrete slab should be a minimum of four inches in thickness (depth). If you are using your metal building to store heavy equipment such as garbage trucks, recreational vehicles, etc., the slab must be five to six inches deep. In these cases, using 4000-psi concrete is also recommended. Cut the expansion joints in the slab as the concrete can withstand the friction. In most cases, it is recommended to complete the sawing process within six to 18 hours from when the concrete is poured. In no instances should you wait over 24 hours?
- Footing requirements – Perimeter footings should be poured at the same time as the slab. Further, perimeter footings should be at least 12” wide and 12” deep. If you are working with a frost line, your perimeter footing might need to be deeper. Remember that you can include the four inches of your slab thickness as part of that 12 inches in depth. Be sure to check your local building code for any other sizing requirements, as rebar may also be required along the top and bottom.
Setting your Slab and Building Location
There are many considerations when determining where to install your metal building. One of the first considerations relates to size. Start by deciding how large your facility will be and how you will use it. Understanding the desired size will help you narrow your property locations where the building will be the most functional. Once you have the size figured out, you will also want to consider the following:
- Property line and setbacks – You will want to consult the plat map for your property to ensure you don’t inadvertently plan to build on a space that falls outside of your property line. Further, most jurisdictions will require that your metal building is set back a certain distance from that property line. This information is usually made available as part of the building permit process.
- Accessibility to your building – Now that you know how you will use your structure and the size it needs to be, you will want to consider how and where people will most easily access the building. Ensure that the access point to the building is straight-on and that there is no landscaping in the way. Further, ensure that your facility is within reasonable proximity to a main electrical supply.
- Grade or water control – If your building is installed at the bottom of a hill, you will need to have the land regraded so that rainwater flows away from the building. If possible, install your metal building on higher ground.
