Pricing

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 consultatively compose pricing plans for each project.

Approach

Every campus, site, and facility pose 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. We Intelligently Visualize The Built World™ from facility mapping to utility locating prior to excavation, and will perform the right service for your scope of work.

Mapping and modeling - GPRS - Ground Penetrating Radar

mapping & Modeling

GPRS improves project planning and communication by providing clear and understandable maps and models to help you Visualize The Built World™ and share your vision with subcontractors, designers, engineers, and others, easily.

GPRS delivers the most up-to-date, accurate and comprehensive site data possible in the format required for your project.

Our Mapping & Modeling Team can create a wide variety of customizable maps and models, from a simple GPS-enabled map of your utility locate, to highly-detailed 2D CAD drawings and 3D BIM models, depending on your needs.

AS BUILT DRAWINGS

Existing drawings don't always show the current conditions of a site. Drawings that are produced in the design phase of a project don't always reflect the exact location of the underground utilities and current as built site conditions. Renovations, repairs, and additions can all render as built drawings out of date. The GPRS Mapping & Modeling Team can deliver up-to-date as built drawings that reflect the actual vertical and horizontal position of underground facilities & features, and structural, architectural, and MEP site details.

2D MAPS & 3D MODELS

Utility locates, concrete scanning, and 3D laser scan data can be processed into up-to-date 2D maps and 3D models to ensure that your team has all the information you need to get the job done right. These maps and models provide an accurate record of utility locations and as-builts for project planning.

The GPRS Mapping & Modeling Team will deliver point cloud data, 2D CAD drawings, 3D BIM models, 3D meshes, TruViews, and virtual tours produced with the highest quality standards. We provide high-precision custom analysis and calculations such as dimensional callouts, tank calibration analysis, floor flatness and levelness analysis, deviation analysis, deformation analysis, volume calculations, wall plumb analysis, and more.

Maps, models, and analyses are produced and hosted for your use at any level of detail in a variety of formats such as Revit, AutoCAD, ReCap, Navisworks, Civil 3D, BIM360, A360, Bentley, Leica Cyclone, Cintoo, NavVis Ivion, and more. The GPRS Mapping & Modeling Team has optimized workflows for importing data, registration, creating maps and models, quality checks, and transferring data to clients. We deliver the data you need in the format you need to access up-to-date and accurate facility and infrastructure information.

SITEMAP^® MOBILE APP

When we conduct an underground utility locate, GPRS stores all subsurface infrastructure data in SiteMap^®, a secure digital platform that houses all your utility locate PDF and KMZ files. You can access your data from any laptop or mobile device and securely share it with your team. Within your files, you will find interactive subsurface maps, annotations, and more, where you can toggle layers and lines on or off to streamline information and communicate only the data you need. You can even measure site features and segment maps geographically to drill down to specific project points for prefabrication or excavation needs.
‍

GPRS Project Managers can complete multiple mobilizations to a jobsite – before, during and after construction – to record subsurface and as built data in real-time. The data captured can be tied together into living maps and models and saved into a database for reference.

How can GPRS can help you streamline your next project to Intelligently Visualize Your Built World™?

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.

Embedment

Our highly trained Project Managers have extensive experience locating conduits, rebar, cables, pipes, ducts, sleeves, and other hazards embedded in concrete slabs and other structures with ground penetrating radar technology. Cutting, coring, or drilling into these objects can cause damage to utilities and jeopardize the health and safety of workers on site.
