About us

John S. Apolis, P.E., President of C, offers over 30+ years of experience in Structural Engineering Design for almost every type of construction project. We have provided design many types of structures. Our design costs are often lower because as a smaller firm, we have lower overhead costs. In addition, our turn-around times often are faster, because of the way we organize our work schedule. We typically provide full structural design for additions and remodel projects for 100 or more satisfied architects and homeowners each year, as well as a similar number of smaller "one day" or even "two hour" projects. We try whenever possible to give you what you need, when you need it. No project is too large or too small. If you are looking for a structural design firm which will stand behind their work, and provide you with timely and cost-effective structural design for your remodel, look no further.

Did not actually look in the attic to verify where any of our ceiling joists were located. Charged me $500 to stand in my living room and confirm everything I already knew.

This person was not able to help me, and I received no deliverables for my $600 fee. Only told the project wasn't feasible. Found another engineer who was able to help.

John was easy to work with and responded quickly. My project was a pretty straightforward kitchen remodel requiring removal of a wall and so involved my HOA. John very readily clarified when the HOA had questions, and provided an amended letter.

Quick reply and accommodated our fast schedule to have a structural inspection on a home we were offering on. Showed up on time. Very casual, which is OK, but I felt like I was leading the inspection, he only answered the questions I asked and only looked at the areas I asked him to look at. Requested a **quick** written report of the inspection but never received it. In the end, this does not really matter for us (we did not get the home), but given the price, and the fact only 20was spent at. the property I expected more for the cost.

John came out and looked at several issues, determined them to be cosmetic not structural and wrote a certified letter to that effect. We got great peace of mind from his visit.
