Frequently Asked Questions
Before breaking ground, it is important to understand where buried power, gas, water, sewer, and telecom lines are. With the field-verified utility data collected by GPRS, contractors on site can avoid utility strikes and stay on task.
Some deliverables clients can expect to receive when working with GPRS on EV charging infrastructure projects are:
• High-resolution utility as-builts (PDF or KMZ files)
• Above and below-ground facility and infrastructure mapping
• Conceptual site models (CSM)
• Concrete markings and mapping
• As-built creation and existing conditions documentation
Contractors use SiteMap to access information directly on the job site. They can view utility locations, reports, and drawings on a tablet or laptop.
Having this information in the field saves time and keeps workers safe.
With the role-based access, Subcontractors can use SiteMap to see only the information they need for their jobs. This helps them understand where utilities and structures are located without confusion.
Subsurface Investigation Methodology (SIM) is a standard operating procedure and set of professional specifications that work as a guide for utility locating experts when scanning for buried utility lines. All GPRS Project Managers are required to achieve SIM 101 certification, which requires 80 hours of hands-on training in a classroom setting and 320 hours of mentorship in the field. For reference, the American Society for Nondestructive Testing’s (ASNT) minimum training recommendation includes eight hours for training and 60 hours practicing GPR to achieve NDT Level 1 certification in ground penetrating radar (GPR) scanning.
SIM requires the use of multiple, complementary technologies, like GPR scanning and electromagnetic (EM) locating, when locating buried utilities or scanning a concrete slab.
