Q: How deep does a monolithic slab need to be?

• <div><p>The depth of any foundation style depends on your climate and how deep the frost line is, as building code requires that the footers of a foundation&mdash;which are built into a monolithic slab&mdash;sit at least a foot below the frost line. At the southern tip of Florida, for example, a monolithic slab foundation would only need to sit 12 inches under the soil at the widest parts. On some parts of the Canadian border, the frost line is 100 inches, which would mean a minimum of 112 inches, which is prohibitively deep for a monolithic slab.</p></div>

Q: What types of projects require a structural engineer’s expertise?

• <div><p>Structural engineers are necessary for projects involving alterations to load-bearing structures, foundation work, and compliance with safety standards. This includes home expansions, retaining walls, and significant repairs that impact a property's integrity.</p></div>

Q: Are foundation walls load-bearing?

• <div><p>Yes. Foundation walls are always load-bearing.</p></div>

Q: How do contractors cut a doorway in a concrete block wall?

• <div><p>First, most contractors will have a structural engineer create a report and plan for your project to ensure it&rsquo;s safe to cut into the load-bearing wall. The contractor will then excavate around the wall, if necessary, measure the opening&mdash;allowing for additional space to fit and level the door, and then cut the doorway out. They will likely install a steel lintel as a header over the door for support. Once the doorway is cut out, they&rsquo;ll demolish the concrete using sledge hammers and masonry chisels, clean up the surrounding concrete, and seal around the door with masonry mortar. </p></div>

Q: What is the 10 10 rule in construction?

• <div><p>The 10 10 rule describes the formula most contractors use to determine how much to charge for a job. Allowing for 10% overhead above the total projected cost to do the work and 10% profit sets a contractor up for success, even if there are delays or other problems on the project. This formula isn&rsquo;t a hard-and-fast rule, but it is a ballpark figure to begin with when estimating your expenses on a job.</p></div>

"Due to a large crack in my ceiling, I thought I might have a structural issue. Hogan Land Services was prompt in sending someone out to take a look at the issue. After a quick inspection of the attic and crawl space, they determined there were no structural issues. Therefore, there was no need for a structural engineer. Here we are a couple years later and doors are not lined up, the crack in the ceiling continues to get longer and wider, and more cracks in the ceiling and walls. Hogan Land Services was quick to reply to my concerns, giving more information on what could be causing the issues I'm experiencing and what route to take to alleviate the issues."

The contractor will then excavate around the wall, if necessary, measure the opening—allowing for additional space to fit and level the door, and then cut the doorway out.
