A common issue many homeowners have is they eventually run out of space. When this happens, their options include adding on to their home or moving to a larger one. But with limited space in urban areas, you may not have enough space to build out, so building down is your only option.
With underground homes becoming more popular worldwide, people are becoming more open to transforming their basement into a habitable living space. Of course, basements aren’t designed to live in, so some significant work has to be done in order to make them livable and safe.
Important Considerations of Adding Subsurface Levels
When structural engineering consultants do any work to basements, they have to take several things into consideration:
- Structural Support – your home has to have the proper structural support down through the basement area in order to add subsurface levels. If an existing basement floor is lower than the underside of foundation walls, then the structure will not settle properly and could lead to collapsing.
- Benching – this is the concrete bench built on top of a stable excavations slope. It’s an important process for structural engineering consultants, so be sure to learn about the process so you know your contractor is well-versed and qualified.
- Underpinning – this is a necessary task if your basement floor is lower than the underside of your foundation wall. You have to excavate below the existing wall and add concrete to essentially extend the foundation downward.
The Role of Facade Engineering Companies
All structural engineering companies have to do a thorough analysis of your existing structure prior to doing any work. Inspections must be thorough in order to ensure safety and security of the structure prior to, during and after the building process. Always ask for the qualifications of any structural engineering companies you work with so you can feel comfortable with the service provided.
Challenges With Adding Subsurface Levels
Any time you add a subsurface level to an existing structure, you are going to run into some challenges. Some of those challenges include a shallow sewer drain, being too close to another structure and problems with the soil during the excavation process. Some of these issues can be found during the inspection phase, but others may only become known during the building process.
At BE Structural, our engineers are well-versed with adding subsurface levels to existing structures. We ensure thorough inspections are completed so there are minimal surprises during the entire building process. If you’re in the need for some extra space and want to build downward instead of upward, give us a call to see how we can help.
