"I am having a full master bath and kitchen remodel done with new layouts in both rooms and knocking out a wall. Evolution worked with me to quickly get a drawing done of the new layouts so that the contractor could get started on the project. They made sure to include me in the process so that the design would be done exactly as my wife and I envisioned. They communicated effectively throughout the process and were always courteous and professional. I recommend them to anyone with drafting needs."

"I was looking for someone to handle blueprints and engineering for a home in the Florida Keys. Having built homes before, I’m familiar with the process and already had some sketches with a few changes I wanted to make. I found Evolution Drafting online, and Kristine walked me through everything clearly. Lindsey was assigned to my project after a quick introduction and a follow up she was AMAZING to say the least! The initial drawings were excellent, and any changes I requested were completed within days. Compared to another project that took nearly a year, this was incredibly fast and detailed. My wife and I are very impressed. I highly recommend Evolution Drafting LLC—ask for Lindsey on your project. Truly top shelf!!"

"He was out of business because he had chosen to try another profession.  Two weeks ago he gave me a call and said he was back in business.  My brother has used him extensively and I've used him for several projects.  Now that he is back in business, I'm having him come back and do some projects for me.  His name is Daryl Fegatto.  I highly recommend him and in fact I have recommended him to others.  His license ensures free estimates, framing, roofing, siding, room additions, custom decks, trim carpentry and hardwood.  He did siding when my brother built his house.  He did my brother's basement and he may end up getting mine when that time comes.  He made my garage from 20 by 20 to 20 by 30 and he reroofed all that about eight years ago.  He has purchased some land, built homes and sold them.  He has a tendency to over build which we pay for but the projects he does is going to last.  He is not fly by night kind of operation."

Structural Engineering questions, answered by experts

No, beams are the primary load-bearers for flooring or roofing systems, and they distribute the weight of the structure to your foundational supports, while joists bear far less weight and distribute their loads to the beams. Beams are usually thicker and longer, and they have support posts or foundation walls beneath them for support.

All foundations have footers, including monolithic slabs. In some cases, the foundation itself acts as the footer, as in the case of a floating slab and a monolithic slab. With a monolithic slab, the footers—which are just the bottom-most portion of the foundation that distributes loads down to stable soil—are a part of the main slab and are constructed with a single pour.

The essential difference between an architect and an engineer is that architects typically focus more on the aesthetic design of buildings, although not without consideration for the structural integrity of the building. Engineers focus more on the structural, technical, and practical aspects of whether and how an architectural design can be built as drawn. You may need to hire both types of professionals if you’re designing and building a new home.

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.

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