Marathon is well known in the CNG industry for detailed drawings and specification packages and for rigorous construction inspection. Inspection is a critical element in ensuring the quality and safety of a CNG station project. Marathon acts as your expert to ensure that your project is fully compliant with all codes and specifications.

As part of our full suite of services, Marathon often continues our role after the design phase through the construction and commissioning phase.

Marathon is available to provide construction inspection and commissioning services on projects not designed by Marathon, or to provide a post construction third party expert inspection as is required by some Authorities Having Jurisdiction (AHJs).
