Design/Build & Remodel Construction

GPRS has long held to the belief that if there is a tower crane involved on a construction project – we will be there. This has held largely to be true over our last 20 years serving the construction industry. Daily, GPRS works on the highest profile construction projects across the country, scanning concrete and locating utilities on private property. Design-build construction projects vary in size from the $100s of millions to $10s of thousands.

The scope for design-build projects is planned in advance, but the need for our services still exists in these scenarios. Change orders can take place due to design changes, steel embed plates can be missed, concrete sleeves and block-outs can be missed or incorrectly placed, tenant finish design requests and other unforeseen circumstances. When these changes take place, Ground Penetrating Radar Systems is there to deliver critical information regarding concrete slab contents. GPRS Project Managers use concrete scanning gpr to locate electrical conduits, rebar, post-tensioned cables, pre-tensioned cables, nelson studs, welded wire-mesh, concrete beams, and even to determine concrete thickness and cover. A Design-Build construction project can present many challenges in gaining access to a scan area. GPRS is able to use our ground penetrating radar (GPR) equipment to tough-to-reach areas by way of a lift, scaffolding, ladder or even a swing stage. These tools allow the scanning of elevated decks, slab-on-grade, hollow-core slabs, exterior walls, pan decking, concrete columns, core walls and any vertical or horizontal concrete surface.

While most projects that are new construction require GPRS Concrete Scanning services, our local utility locating team is needed as well. GPRS is able to mobilize to project sites before the project begins in order to map the location of underground utilities. When utilities are located prior to a project beginning it allows General Contractors to keep the job site safe through damage prevention. Our utility maps and drawings are able to be used throughout the project as construction is completed.

Rather than send a rigid rate sheet to prospective clients, GPRS can create a customized service plan. We take into account our industry experience, national footprint, and operational/scheduling capacity to craft a customized plan just for you.


With one single point of contact for you company, GPRS can schedule utility locating, video pipe inspection, and concrete scanning projects for your site with one simple phone call.

GPRS has Project Managers in every major market in the US and our single point of contact will simplify your scheduling process.


GPRS understands that clear, understandable, and consistent pricing is a big deal. Our nationwide footprint allows us to streamline our costs on a nationwide basis, we are sure to craft a cost structure that makes sense for the scope of work. Rather than send a blanket rate sheet, we consultaively compose pricing plans for each project.


Every campus, site and facility have different challenges. Since our inception, GPRS has completed hundreds of thousands of projects and relies on that experience when crafting a site-specific plan for safety, scanning and reporting. With the SIM Specification as our guide, we will craft an individualized approach to each and every project. From facility mapping, locating prior to excavation, to performing one-call locating - GPRS will perform the right service for your scope of work.

One Call Program

GPRS exceed industry performance when it comes to the accuracy of our utility locating. Our team of Project Managers can continue the support of your project by crafting a one-call program from when your project transitions to the O&M phase.

Public Property

Damage prevention is critical when excavating in a public right-of-way. Using the 811, call before you dig system, is an essential step to take when trying to avoid underground utility strikes. It's the law! GPRS is able to contract and perform one-call type utility locating for your underground assets.

Private Property

A utility locate on private property is not complete until a private utility locator like GPRS has been called to comprehensively locate the entire campus. GPRS can create a one-call type program for your facility or campus in the case that you have utilities that lie within public property.


GPRS can place our highly trained PMs within your facility or campus to perform utility locating and concrete scanning services. When our PMs are placed within a facility, many benefits realized when compared with our standard services. Our schedule is at your disposal, there is familiarity with site intricacies, and we can manage as-built drawings for the entire site.

As-Built Drawings

As-built utility drawings don't always show the current underground conditions of a site. Drawings that are produced in the design-phase of a project don't always reflect the exact location of underground utilities. Over time, due to renovations, repairs, and additions, as-built drawings become out of date. GPRS PMs are able to update as-built drawings so that they reflect the actual vertical and horizontal position of underground facilities.
