What Do Structural Engineers Do?

Structural engineers bring a specialized expertise to every phase of construction projects, such as building materials, weights and forces, and methods of construction. They conduct feasibility and safety inspections, consult on design plans, produce structural analysis reports and blueprints, and work with their clients to assure that projects are constructed safely, thoroughly, and are compliant with the Building Code. Structural engineers are typically licensed by the State as a “PE,” or Professional Engineer, and have a stamp to certify that building plans meet Code requirements.

What Are Lateral and Gravity Calculations?

Lateral and gravity calculations are the tools that a structural engineer uses to determine what size and strength of materials are required to make a building stand the test of time. Lateral loads are forces that act “horizontally” on a building, such as wind gusts and seismic earthquake shaking. Gravity loads are forces that act “vertically” on the building, such as snow on a roof, people on a deck, or a stone counter in a kitchen.

Is a Project Feasibility Assessment Right for My Project?

In short, yes. Any potential construction project that will modify your home’s structure should be reviewed by a structural engineer, so that you know your options going into the project and are aware of potential complications and anticipated scope of work. Having an evaluation from a professional structural engineer also provides you with an unbiased analysis of what needs to be done, before you start approaching contractors for bids (and start getting a variety of different answers).

Does Someone Need to Look in My Crawlspace or Attic to Know if a Wall is Structural?

ABSOLUTELY! Original blueprints of your house, in combination with accurate photos and a remodel plan, may be used for a structural assessment. However, the structure that is supporting your home is too important to modify based on an educated guess. If you are working with a contractor or designer who is not willing to perform a complete inspection, you are likely receiving incomplete information. An inspection of the attic or crawlspace is required to verify conclusively whether an existing wall is structural.

All About Permitting and Building Code Compliance

All new construction projects and remodel projects that involve work on structural elements should consider a building permit. We recommend that homeowners contact their local City or County permitting office before starting a project to see what submittal information will be required for your particular job. The most reliable route to ensure that your building permit application is approved smoothly is to have professional blueprints and engineering documentation provided from a structural engineer. Most building permit offices require a licensed engineering (PE) stamp on the blueprints to pass permit review.

Does My Project Need Independent Construction Inspections?

There are several factors to consider. It depends on the size and scope of the project, the complexity of the work being done, and your confidence in the builder. Keep in mind that City/County building inspectors are busy, unfamiliar with your project, and don’t spend very much time onsite reviewing the work. It is often a good investment to have the engineering design professional who created your blueprint set verify that the project is progressing according to plan with the correct materials and building techniques as specified in the project blueprints.
