Although the variety and end-uses of recreational construction projects is certainly large, the requirement that they be completed within budget is certainly paramount to their success.  Most recreational projects are publically funded through municipal, educational, or park district entities and often represent significant capital improvement projects not often tackled by these entities.  INTERRA understands the need to provide its services in a manner that moves the project forward as quickly as practically possible and that ongoing communications over the entire project’s duration is highly valued by all parties involved.  As this is how we always contribute to our projects and project team, INTERRA is an excellent selection for your next recreation construction project.
