Inspection

Assuring that construction projects are delivered according to specification while meeting the objectives of the project owner is of critical importance to any project’s success.  INTERRA’s field inspection and field testing professionals fully realize that even the best engineering can be completely undermined by inferior construction practices and materials.  INTERRA, as owner and client advocate, helps bring confidence and trust that your project is being constructed as specified.
