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 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.

Dormers must be able to bear the load of their own construction and the added window. The style of the dormer, however, will determine where the weight loads onto your home's structure. A gable dormer bears the weight on the side walls whereas a shed dormer bears it on the front walls.

No, squeaky floors do not always mean there is structural damage. The noise is often caused by friction from issues like loose floorboards, gaps between the subfloor and joists, or loose subflooring. While many squeaks are harmless, persistent or worsening noise could indicate a more severe problem. If you notice other signs of structural damage—such as soft or sagging floors, cracks running from the wall to the ceiling, or horizontal cracks in your foundation—it's best to have a professional inspect your floor to determine the root cause.

Failure to compact the soil during construction is the most common cause of leaning retaining walls. In addition, poor drainage can lead to excessive water pressure behind a retaining wall, pushing against it until it begins to move forward away from the soil it is holding back.

A construction manager is particularly useful in the case of a large-scale build with custom design elements, so it’s usually worth it to hire one. They can help manage your budget, maintain quality control, oversee timelines, and navigate unexpected hurdles. While construction managers are pricey, they can actually save money in the long run by identifying cost-saving opportunities and ensuring the project stays within budget.
