"I contracted with TVP for engineering plans for a home addition in February, 2023. The sales person Phil McDodson, made an agreement to stay with the project through to the permit but walked away as soon as the county required additional information. At that point Janae Spinney stepped in and would not quit on me until that promise was complete. A special thanks to Joseph and Caleb for getting us through to the end. Every engineer and staff member with TVP was polite, knowledgeable and saw the job through. It was just approved January, 2025. Great company and I appreciate all you did for us!"

Structural Engineering questions, answered by experts

Costs depend on furniture type, size, complexity, and whether additional modifications are needed.

A split-level home is one that has several staggered floors connected by short staircases, while a split floor plan separates the primary bedroom from the rest of the bedrooms. Split floor plans are most often found in single-story homes, while split-level homes are always at least two stories.

A 4-inch-thick concrete slab can support around 4,000 pounds per square foot if a contractor reinforces the slab with rebar, while that same slab without reinforcements will support closer to 1,000 pounds. For the purposes of a patio, 4 inches in thickness without reinforcement should suffice unless you’re installing heavy kitchen equipment or a hot tub on it. In those cases, reinforcing your slab and sticking with 4 inches of thickness should provide plenty of strength.

Yes, professionals reinforce the foundation with additional supports or piers to prevent future sinking.

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—which are built into a monolithic slab—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.
