David was on time and very professional. He spent an appropriate amount of time evaluating the 2 areas we had requested. He documented the inspection w/ photos, measurements, and sketches. He provided a verbal preliminary report and is to provide a written final report w/ specifications for the mods we are proposing. (Removing a wall upstairs and a post downstairs.) We were happy to hear that our mods were going to be less complicated than originally thought and consequently less expensive. We have the peace of mind that the proposed changes are structurally sound and will be done correctly.

Structural Engineering questions, answered by experts

Structural engineers draw structural plans, which include detailed drawings of the structural components of a home only. Complete house plans will require additional work from an architect or draftsperson, whose drawings will take the structural drawings into account. They’ll also include more details about the finishing materials and layout of a home, including everything from roofing and flooring materials to the position of furniture, light fixtures, switches, and plumbing fixtures.

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.

Most structural engineers offer free quotes, regardless of the size of the job. For simple inspections when buying or selling a home, engineers typically charge a flat fee that may be based solely on your home’s foundation type and square footage. For larger projects, like new construction and major home renovations, an engineer will either perform an analysis of your project and site and provide you with a formal estimate, or they will do a more in-depth assessment and in-person site inspection before coming up with a per-hour or per-project cost estimate. In most cases, the estimate is free.

Absolutely, as it ensures designs are viable and won’t compromise structural integrity.

Precast concrete can be reinforced with rebar, wire mesh, or other materials to improve its strength and add stability. Precast concrete for large construction projects is often pre-stressed as well for greater structural strength. Reinforced concrete is durable and strong, making it an ideal choice for many construction projects.
