"I was really under the gun due to a prior Architectural firm not performing their duties per building plan codes. Not only were the plans incomplete but the City Plan Reviewer states(The Worst plans he’s ever seen) they will not make adjustments unless there is an additional charge for Thousands. Evaluation’s saved my clients and drew our project per code, along with Engineering in less time then they quoted. I highly recommended them, Especially Kirsten. You went above and beyond trying to coordinate this project. The staff was very professional and I will use them on all my projects. Sincerely, Frank B BCM Builders"

Structural Engineering questions, answered by experts

Costs depend on material choices, labor, and the extent of structural modifications.

It is not recommended to cut or drill into LVL (laminated veneer lumber) beams. As major structural components of a home, their composite structure can be compromised by alterations, which can weaken them and lead to cracking over time. If you must make modifications to an LVL beam, it is crucial to consult a structural engineer or general contractor first. A professional can advise on whether it's safe and provide specifics on the appropriate bit size, depth, and directionality for any necessary drilling.

Yes, ceiling joists are typically load-bearing. However, their primary function is to support the weight of the ceiling and loads applied to it, like lighting fixtures and ceiling fans. They can also help support the roof, especially if they’re part of truss systems. Remember, the load-bearing capacity of ceiling joists depends on the material, size, and space between them. 

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

Yes, a one-story house can have a load-bearing wall. The load-bearing walls in a single-story home are usually the exterior walls. If the house has a basement with exposed walls, the arrangement of the beams can help indicate what walls are load-bearing.
