Benjamin Birch, P.E.

Senior Engineer


  • Concrete + Cement-Based Materials


Mr. Birch has extensive experience working with high-performance concrete from mixture proportion development to the evaluation of many fresh and hardened properties. He has developed CTLGroup’s testing capabilities in the area of unique and challenging test methods. He has experience working with self-consolidating concrete (SCC) both in the laboratory and in the field and has studied the factors influencing formwork pressure exerted by SCC. He has helped clients identify safe casting rates with SCC so as to not risk the integrity of their forming system while still maintain economical placement rates. Mr. Birch also has extensive field experience with evaluation of in place structures through visual observation and the use of nondestructive testing (NDT).

Mr. Birch has a great deal of experience related to concrete pavements, and a lot of his prior experience involved evaluation of airfield and roadway pavement at installations ranging from small general aviation airfields to large commercial service and military installations. He is well versed in evaluation of mixture proportions for properties specific to the needs of pavement and associated specifications.
