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.

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.
