Construction Inspection & Administration

Are you building a new subdivision? Adding pipe utilities to your neighboring lot? Pouring a new driveway? Madison Engineering has inspected hundreds of construction related projects in the Gallatin valley.

Including density testing of soil and asphalt with a nuclear densometer, obtaining grade elevation shots of underground utilities and creating concrete cylinders to ensure compressive strength. Madison engineering has been hired to inspect construction projects of a wide variety of sizes over the last 17 years in the surrounding valley. Inspection needs vary from job to job and Madison has the experience and capability to successfully meet your inspection requirements.

Madison Engineering has well trained engineers that all see field inspection to properly understand the construction installation process. This gives us our team the opportunity to assess each job and its unique challenges.

Depending on project location and municipality requirements, construction inspection can include:
  • Compaction testing of sub-grade, sub-base, base and asphalt material.
  • Elevation grade shots of underground and above ground utilities.
  • Concrete testing of material to verify state specifications for workability, air entrainment and compressive strength results.
  • Coordination and communication with contractors.

      Construction Inspection

      Compaction Testing

      Most design standards and specifications require some type of density testing within the right of way. We utilize nuclear densometers to verify and ensure the soil is properly compacted before a roadway opens up for vehicle traffic. We coordinate with the installing contractor to achieve satisfactory results for your project.




      Laser Level



      Construction Inspection

      Elevation Grade Shots

      To ensure that the utility installation is being installed per design and is within city specifications, our on-site inspector is properly trained to use a laser level and grade rod. This allows us to verify that the utility is being installed at the correct elevation and is not deviating from plan. By taking the proper elevation shots we are able to submit adequate as-built information after the project has completed.

      Concrete Testing

      We provide our clients with the ability to concrete test driveway approaches, valley gutter and any concrete related items being poured within the public right away. We ensure that the state specifications and proper concreting testing procedures are followed during your project. We create concrete cylinders that are tested for compressive strength to verify that the proper mix design is being poured on your project.

      Density Compaction Testing

      At Madison Engineering our construction inspectors are all certified in radiological and operational training. We utilize nuclear densometers to ensure that the subgrade, subbase, base and asphalt are compacted properly.

      Elevation Grade Shots


      Madison Engineering provides construction inspection services that include elevation grade shots. Elevation grade shots are required to ensure utilities are being installed per design and City standards.

      Concrete Testing


      Pouring mud in the right of way? Madison Engineering has certified ACI technicians that can perform slump, air and cylinders for your project.
