"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."

"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.

"Todd has been a pleasure to work with. We asked him for help in designing plans for a renovation for our 1960s home. The existing home had a one-car garage, and we wanted to expand that to a two-car garage and add an extra room for a second work-from home office, as both my husband and myself work remotely. After reviewing our lotâ s survey, it was discovered that we were too close to the property line to expand the current garage, which necessitated putting the new garage on the other side of the house. This added another layer of complexity to the project, as we now needed to incorporate the existing single-car garage space into our home as usable living area. Todd listened to our ideas for repurposing the space, and provided good recommendations of his own. As others have mentioned, he worked well with our builder and quickly answered questions from the county permit office, expediting the permit approval process. We would have no hesitation in using Todd for our next 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

While concrete walls do not need to "breathe" in the traditional sense of the word, they do require waterproofing and dehumidifying methods, particularly in basements below the water table. Concrete both contains moisture from its initial installation and can absorb water when exposed. Ensuring proper basement ventilation , installing a vapor barrier, and controlling water exposure are all important tasks.

You should pick steel for your new support beam for a few reasons. While steel is more expensive than other materials, such as laminated veneer lumber or glulam, it offers the following benefits:

  • Fire-resistant

  • Unaffected by pests

  • Longer-lasting

  • Stronger against water damage (when galvanized against rust)

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.

A few hours for inspection, with a detailed report following in a week.

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.
