Testimonials

Allen Browning, M.S., P.E.

Our company worked with C3S Inc., on several projects. The services provided by C3S Inc. in regards to Petrographic Analysis of concrete cores from damaged areas were vital to the evaluation.

In our opinion, C3S, Inc., not only provided reliable information, they also did it within a short amount of time to help maintain timeframe and budget limitations.

MTA Engineers consulted with C3S on several commercial, state and federal projects. Most of the projects have been related to issues with concrete or quarried stone. The response from C3S has been timely and accurate. MTA will continue to contract with C3S on future projects.

Paul L. Roberts, P.E.

C3S, Inc. was contracted on our Harbor Villa Project. This property in Honolulu, HI, required evaluation of the structure to determine the existing damage and remaining service life pending a planned renovation. The report was very comprehensive and was received in a timely manner which enabled the project to move forward quickly.
