“My expectation of individuals who perform services for the company that I work are high. Elizabeth responds quickly, performs her work as required, and is quite pleasant to communicate with.”


Kertsen Rutherford, MetroPCS

“Elizabeth is a top notch professional who gets the job done each and every time. I highly recommend her to take care of your project needs!”


Steve Rickenbacher, DPR Construction

“It is with pleasure that I provide this letter of recommendation for Mike Clarke of Clarke Inspections, as a DSA Class 1 Inspector of Record. As the Project Architect for the Foothill College Physical Sciences and Engineering Center, I have worked closely with Mike for the past 14 months of the project’s construction phase. Throughout that time, Mike has provided valuable oversight to the construction process, ensuring that contract and code requirements were adhered to, and that the project was constructed to a level of quality expected by the Client, the Foothill De Anza College District. Mike has also worked closely with the District’s Testing Laboratory, and the DSA Field Engineer to ensure that the project will achieve DSA certification upon completion.  He has proved to be very diligent, and I would recommend him for any project requiring a Class 1 DSA inspector.”


Robert J. Williamson, AIA, Ratcliff Architects

“Mike was the IOR for Nightingale Elementary Classroom Replacement Project for Stockton Unified School District. The project was a modernization where modular classrooms were replaced with permanent classrooms, along with some minor upgrades to a very old campus. Mike's extensive knowledge of DSA Construction combined with his user-friendly attitude made a somewhat challenging project very smooth and economical. His ability to provide key advice to Owners, Architects and Contractors made it easier to avoid pitfalls that would end up costing money and time. In fact, the Change Order percentage for the project was about 3%, including Owner Changes. This is unheard of for Modernization Project.”


Mike Mastagni, Project Manager, Acme Construction

“Elizabeth has always responded very quickly to our request for proposals and the immediate need for special inspection services. Her work has been detailed and accurate with no surprises. She has always been very professional and fair in contract negotiations.”


Ric Collins, Salas O'Brien Engineers

“I became familiar with Michael Clarke during his employment with the Lammersville Elementary School District in 2007. During that time, he was the DSA Project Inspector for a new 20-million-dollar K- t2 Elementary School in the community of Mountain House and I was the project Architect. That school was completed on time and under budget due to   a strong team effort which included the District, General Contractor, Architect and Project Inspector.”


Robert A. Machado, AIA, Architechnica

“Elizabeth and her team are always on top of things. In the fast paced construction world this is almost as good as gold.”


Carl Crizer, Salas O'Brien Engineers

“Through the course of the project I had the opportunity to work with several of Structure Consultant's inspectors. They    all possess the necessary certifications, credentials and experience to perform the duties of the IOR, however, they take the position of Inspector of Record to a new level. All of Structure Consultant inspectors are well trained and possess a wealth of experience. Their technical back ground, combined with a working knowledge of the building code makes their inspection process flawless. Nothing gets overlooked or missed.”


 Ron Deller, Foothill College
