SJB Group Industrial Services


SJB Group, LLC is a multi-discipline firm based in Baton Rouge and serves Louisiana and the surrounding

states. The firm was established in 1953 and has grown to provide a robust menu of services including

topographic and boundary land surveying; 3D laser scanning with mobile and drone LiDAR; subsurface

utility engineering; land planning and parks/recreation; commercial, residential and multi-use center

development; municipal infrastructure for roads, parking, drainage, water, wastewater, and natural

gas utilities and pipelines; permitting; construction scheduling (CPM) for private and public works; and

forensic analysis and testimony for the engineering and construction markets.


Subsurface Utility Engineering (SUE) is a highly-effective and non-destructive

service that provides accurate locating and mapping of underground utilities

and subsurface assets. Using a light and mobile vacuum excavation truck, SJB

Group dentifies the precise horizontal and vertical locations of utility lines, pipes,

cables, buried concrete, and other unseen objects. Our service eliminates

potential conflicts and leads to more informed design and construction

decisions, which saves our clients time and money. Most importantly, this

practice protects life and property. We stand behind SAFETY.


Natural Gas Distribution & Pipeline Compliance Support

When it comes to utility system projects, SJB Group can help you play by the rules and regulations and

still keep your project on track. With our roots in utility management and operations, SJB Group is very

familiar with utility requirements, codes, and regulations. Understanding how regulators think helps us

interpret their guidelines. Over the years, we have honed these skills to ensure that plans and designs

for utility expansions and upgrades are practical and affordable while complying with the fine print.

SJB Group has the experience and ability to understand the capital costs associated with projects,

and we work to develop the most effective alternative–both immediate and long-term–especially with

regards to maintenance.


SJB Group knows how budget cuts may affect not only the quality of your project, but also the longterm

environmental impact. We work closely with our clients to understand their goals and objectives,

and then we provide an array of alternatives to help them make informed decisions on everything from

materials and their construction approach to long-term maintenance issues as well as the relocation of

utility systems caused by infrastructure or highway widening and improvement projects.

• Regulatory Consulting/Auditing Services

• Third Party Damage Investigations

• O&M/DIMP/Emergency Plans and Drills

• Construction Management Services

• Engineering/Design/Mapping Services/ GIS

• Damage Prevention/Public Awareness Programs

Mobile Lidar Scanning & Videography


Mobile LiDAR scanning is an innovative solution that uses a combination of LiDAR sensors, cameras,

GPS technology and a mobile platform (car, ATV, drone, helicopter, etc.) that collects data points

much faster than conventional surveying methods. This method is not only faster, but it is safer, allows

for better access to hard to reach areas, and is non-invasive.

Why LiDAR?

• Crews avoid exposure to potentially dangerous circumstances such as busy intersections and highways.

• Lessens disruption to general public.

• Increases accessibility to remote or hazardous environments.

• Incorporates GPS and survey controls for accuracy.

• Cost effective and rapid.

• We offer terrestrial LiDAR scanning and Aerial LiDAR scanning.


Terrestrial Lidar Scanning


While the construction industry is often considered to be a slow adopter

of new technology, design and construction professionals are challenging

themselves to build projects faster and cheaper with the use of technologies

like BIM, tablets, and custom-designed apps. A less publicized technology

in the adoption phase is 3D laser scanning. Engineering and consulting firms

are recognizing the benefits laser scanning can bring to their clients and

operations.


What is 3D Laser Scanning? The concept is simply this. 3D laser scanning

technology uses a line of laser light to digitally capture dimensions and spatial

relationships of an object. The point cloud image that results is an accurate

depiction of the object, which may be scanned from as far several hundred

meters. Accuracy of data points collected can be less than 5mm at speeds

from several thousand to several hundred thousand points per second.

Density of the point cloud affects the speed. A very large object is scanned in one scan, multiple scans

from different lines of sight can be linked together to complete the point cloud image. Data form a 3D

point cloud may be exported into CAD and BIM programs to general 2D CAD drawings or a 3D model.

The detail produced in these scans is much greater than more conventional survey methods. Point

clouds also can improve design by analyzing clashes between newly designed elements and existing

conditions or by evaluation alternative designs prior to construction. These scans reduce project costs

by up to 7 percent and schedule times of up to 10 percent on industrial projects. Scanning can take

hours or a few days depending on the scale of the site compared to traditional collection methods.
