Topcon 3D GPS machine control

Cronin Construction uses Topcon automated suite with dozer and motor grader systems, as well as survey rovers.

Topcon 3D GPS machine control that puts your site on grade, the first time with no survey stakes that may limit access to many areas on the job.

The Survey Rovers system permits us to use corrected GPS signals for survey. This allows one person to fine grade at literally any point on the job site. This system can also be attached to a mobile unit which traverses the site before work begins to map existing conditions ensuring there are no surprises in existing conditions. We use both registered survey crews and GPS rovers as cross checks to insure the site is graded to design specifications.
