My partner and I needed structural designs for a tourism related project in Greece. We were lucky to have selected CAS for the job. To start, our experience was limited in this field, CAS was pro-active and proposed solutions and improvements to our designs. They are able to follow instructions, focus on details and present options. More importantly they were always prompt , responding to our on-going requests for changes and delivering the designs on date. We highly recommend CAS and plan to use their services again next year when we need to expand our products.

I am beyond happy with her work, she has a great vision and team. One of the greatest qualities as a designer is that she has very good taste and respects the clients wishes, also she only offers what is necessary in a project, she doesn’t push jobs that you won’t need in your project. Everything was smooth and straight forward, I actually had some trouble with Guru and Safepay, but she helped me and the experience was very good. I can’t wait for my next project with her and her team, I am definitely hiring her again.

I worked with CAS on a remodel job in Asheville, NC. They did all the necessary load calculations and drawings needed to get my permit on a duplex in hot West Asheville. I ran into a few bumps in the road with the building permit process and CAS was very helpful in over coming the issues. They were patient and helpful and did a great amount of follow up to keep the project on tract. My local engineer was able to review the work and recommend the work to the city for approval. Thanks for your extreme patience.

Imran Rad


It has been a pleasant experience working with CAS. I plan to utilize their expertise in the future also, and can recommend to any other consultant for structural design work.

Ian Kalinowsky President

CEO and owner at Great Canadian Travel Company

CAS was great to work with on a complicated design process involving an existing boathouse which needed a new foundation. The issues were that the structure is built on cribs and is in the water on an island. CAS worked through many design possibilities before determining which was the optimal conclusion for both structural integrity and consideration of materials (ex steel beams were ruled out due to weight and barging limitations). CAS was prompt with replies and their communication skills at explaining difficult options were excellent. I would highly recommend using CAS.

John Braithwaite

Delivers deals, growth and performance for acquisitive businesses and entrepreneurs.

We engaged Maria for some detailed outdoor structural design work for a client. From the onset Maria took the trouble to read the brief thoroughly and asked all the right questions. It suggested a smart and comprehensive approach to the project. Indeed that is what it became – we agreed stages and milestones and each one of these were met, and with detailed professional workmanship. We were very pleased with the polite dialogue, the considered responses, and the quality of work. Certainly we’d recommend Maria, she delivered an excellent service.
Just a great job all round. Really responsive, good communicator and professional. And, of course high quality, clear calculations and directions. Will aim to use again. Thank you.

Patrick Guglhor

PATRICK Guglhor Company Director at PAGUREK

The Team at CAS did and outstanding job on our House calculations . We had a few changes and a few adjustments to do , which they done very accurately and promptly.
All the plans where delivered most of the times 1-2 days before agreed deadlines.
They even added some minor extras to the whole calculation package and the general input into the project was highly appreciated .
Their expertise in structural calculations is excellent and I found it very easy to communicate with them, as replies to each of my request and questions came very quickly.
I also appreciated their patience in explaining certain parts of the project/the calculations to an amateur, as professionals sometimes tend to take certain work processes or standards for granted that are not that clear to an outsider.
This was not the case here and they done a great job in making us understand the scope of her work as well as the implications of it.
The project was a full structural calculation for a detached Passivhouse.
It was delayed for a few weeks in between due to an architect being rather slowish in responding so nothing to do with CAS’s work.
They delivered all calculations on time and accurately.
