Tierra Services


In the planning and design phase, the collection of underground and above-ground facility information reduces the risk, cost and work that accompany engineering and construction projects. Collecting this information provides improved safety, eliminates unexpected conflicts between facilities, and minimizes relocations.

Tierra’s Pre-engineering services provides project engineers with sufficient information about existing infrastructure within design limits and reduce the conflict potential during construction. As a result, the project design will be timely and economically efficient.

Permitting & Permit

Since Tierra is working closely with major municipalities and utility companies, it is very well familiar with municipal and utility technical requirements in order to acquire permits for utility construction. Tierra with its permitting services expedites construction permit acquisition and mitigates permit revisions.

Also, any utility conflicts or unforeseen conditions in the design can cause significant delays or downtime during the construction stage that subsequently causes project delivery delays, increases project costs, and could create grounds for a future claim. Tierra offers permit and route validation service to help clients mitigate unforeseen situations before beginning construction.
