Pre-engineering and Permitting

Learn More


Before beginning a new construction project, it is imperative that all underground and surface infrastructure (assets and asset-related data) is properly recorded and transferred into GIS. This process enables electronic reviewing and planning, effectively eliminating delays and expediting construction. Tierra identifies and maps all necessary geographic elements, producing an extremely accurate map that is informative, accessible, compatible and is ready to be integrated into GIS or converted to CAD.

Permitting & Permit

Tierra provides professional validation of existing permits and engineering plans, to identify conflicts with 3d-party infrastructure and avoid damages during construction. Tierra also offers route validation which allows project managers to view 3D models of conflict points before constriction. Through the utilization of our in-house practices and software, Tierra can eliminate any red tape and get your project moving faster by eliminating downtime during construction, while promoting public safety.
