Construction, Remodel & Design-Build

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. GPRS has worked on some of the highest profile construction projects across the country, providing utility locating, concrete scanning, 3D laser scanning, video pipe inspection, and leak detection services. We can aid any size design-build, remodel, or construction project 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 can occur. 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 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 for 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.

3D laser scanning provides accurate as-built site data to help design-build projects move seamlessly through the design and construction process. Virtual data provides a single source to collaborate and expedite decision making. Accurate data is invaluable in design planning, prefabrication, procurement, and construction. Teams can foresee potential issues and plan specifically around these to prevent problems before they happen. Our Project Managers document each site with the Leica P-Series and RTC360 LiDAR laser scanners, capturing up to 2 million data points per second with 2-4 millimeter accuracy. GPRS’ in-house Mapping & Modeling Team can customize as-built data, 2D CAD drawings, 3D BIM models, 3D mesh models, virtual tours via WalkThru 3D, digital twins, floor plans via FLRPLN, and more with Autodesk Recap, Revit, 3DS Max, AutoCAD Civil 3D, AutoCAD Map 3D, BIM 360, Navisworks, Inventor, SolidWorks, and Bentley MicroStation software to ensure you have all the information you need to get the job done right.

All clients receive instant access to complete and aggregated site records in Sitemap®, GPRS’ digital storage software and app, where data is geolocated, layered, and securely shareable.

Concrete Scanning Services

Concrete scanning is a non-destructive method to assess concrete using GPR to locate, identify, and mark utilities and objects such as rebar, post tension cables, beams, conduits, and piping embedded within concrete slabs and structures prior to anchoring, cutting, coring, and drilling. Concrete scanning ensures the safety of workers and prevents accidents by identifying potential hazards before any work occurs. Concrete markings can be 3D laser scanned to create a permanent record of the site, data can be delivered in 2D CAD drawings, 3D BIM models, and virtual site tours.

3D Laser Scanning Services

GPRS 3D laser scanning services document the exact architectural, structural, and MEP system layout and dimensions of existing buildings and sites. GPRS Project Managers use industry-leading Leica survey-grade laser scanners to capture 2-4 millimeter accurate existing site conditions in the form of a point cloud. Our in-house Mapping & Modeling Team can transform those point clouds into customized 2D CAD drawings, 3D BIM models, 3D mesh models, TruViews, and 3D virtual tours at any level of detail for visualization, analysis, design, construction, renovation, prefabrication, and facility modifications.

Video Pipe Inspection Services

GPRS video pipe inspection services deploy robotic crawler CCTV cameras, lateral launch cameras, and push cameras to inspect and document water, sewer lines, and lateral pipelines to locate clogs, investigate cross bores, find structural faults and damage, and conduct lateral sewer line inspections. GPRS Project Managers deliver NASSCO-certified WinCan reports with the exact location, video, and photo of each defect, ranked by severity so you can plan for maintenance and repairs.

Leak Detection Services

GPRS specializes in all types of leak detection services, including municipal, industrial, and residential. Our Project Managers are leak detection specialists who utilize multiple technologies to locate your leak and have the expertise to map and provide many other insights into your water distribution and/or fire suppression systems. GPRS does this by utilizing a variety of equipment paired with our industry-leading SIM (Subsurface Investigation Methodology) processes. The equipment and methods used include acoustic leak detectors, leak noise correlators, video pipe inspection (CCTV) cameras & sondes, ground penetrating radar, and electromagnetic locating, among others.

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 exceeds 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.
