"Pedram provided us with great service at an exceptional value. He completed the necessary drawings for our structural wall removal, and we were able to get a permit with no comments from the city. I would recommend to anyone looking for a structural engineer."

Customers say: True professional

"We've never done a remodel before. We live in a high-rise and needed to update our kitchen, put in some pocket doors, and a laundry closet. We thought we needed an architect to give us ideas and the structural parameters within which we needed to work. We bought the Big Deal for an architectural consult. Mr. Madeiros was very professional and offered us a few ideas. He is relatively new to the Denver area and wasn't sure if we needed permits for the work we wanted to do. He called the city for us, which was helpful. He gave us drawings of what we had described and his added idea. It ended up that we didn't need his services as we discovered that general contractor could do what we needed. We had the building and unit floor plans and lots of our own ideas, having done a lot of research. I think if you were going to create something out of nothing, his services would be more helpful.

"We have been working with Todd Willoughby since early in 2018. We had purchased a piece of land along the Chesapeake Bay and wanted to build a small but thoughtfully designed contemporary garden cottage for our retirement. After speaking with a number of architects we chose Todd and we have been very happy with that decision. Over several months, we worked have closely with him through the several design phases, culminating in a very complete set of construction documents, that we are now using for bidding. Throughout the process, we have found Todd to be personable, smart, perceptive and creative. He has been able to translate our ideas into working drawings that one of the contractors noted was called the most detailed he has ever seen. Todd has captured our vision for an environmentally friendly house with solar and rainwater harvesting. We have met with him many times talk through the many details, choices, and constraints you inevitably face. He has done all the coordination needed with the other specialties the engineers, surveyor, and solar energy firm. Having enjoyed this first part of the collaboration, we are hiring Todd to help us through the bid evaluations and construction admin phases. The best recommendation would be our actual house, but until we get there we can say Todd has done an excellent and professional job getting us this far, and we look forward to working with him through to a completed project."

"From the start I knew Ryan was the right person, because he called me, the only one of the engineers that actually called me. He communicated regularly, let me know straight up the results and explained it all to me. Is also willing to answer questions from my contractor."

"We had a great experience working with Vital Architecture and highly recommend her. For Little Village Childcare, she helped us save money by confirming certain landlord requests were not required by code and securing a waiver that saved space and costs. She also reduced civil engineering expenses by preparing the playground drainage plan herself. During construction, she provided extra support at no cost and helped us handle contractor changes wisely. For another church childcare project, she identified zoning issues early so everyone understood the risks. In Colorado Springs, she warned a tenant about higher plumbing costs required by childcare regulations, helping them avoid a bad lease. For an adult care project, she reviewed the food area and explained new kitchen and ventilation requirements. Carmen is knowledgeable, thorough, and truly looks out for her clients’ best interests."

Structural Engineering questions, answered by experts

Yes, walls on the top floor can be load-bearing if stacked on the floor’s foundation.

Through proper drainage solutions and compacting the foundation soil.

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.

First, most contractors will have a structural engineer create a report and plan for your project to ensure it’s safe to cut into the load-bearing wall. The contractor will then excavate around the wall, if necessary, measure the opening—allowing for additional space to fit and level the door, and then cut the doorway out. They will likely install a steel lintel as a header over the door for support. Once the doorway is cut out, they’ll demolish the concrete using sledge hammers and masonry chisels, clean up the surrounding concrete, and seal around the door with masonry mortar. 

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