3D laser scanning utilizes eye-safe laser technology to determine where in 3D space an object is. State-of-the-art laser scanners capture millions of data points per second. The data is stitched together, providing a 3-dimensional representation of the existing space within eye sight of the scanner
TruePoint is the industry’s most experienced 3D laser scanning service. TruePoint has provided laser scanning and modeling services for clients in many industries and can quickly mobilize to any site in the United States. We have worked with some of the best-known firms and companies scanning industrial facilities, historic buildings, stadiums, hospitals, universities, municipalities, waste water treatment facilities and more – even new construction verifications. We are a licensed engineering firm that focuses solely on laser scanning. Our team of in-house scan technicians and engineers work with each client to develop an accurate understanding of the existing conditions and create custom deliverables, ranging from point clouds to 2D drawings and 3D models.
At TruePoint, our objective is to capture, analyze, and define the data accurately and efficiently, delivering it the way that you want it. We will need several pieces of information to provide a cost for your job. We know that your time is important, so we will work with you individually to provide you a quote quickly. Both the amount of time and number of scans required depends in part on the structure itself, on the number of levels or rooms, square footage, and whether or not the space is occupied (with people, furniture, fixtures, etc.).
Whether you are new to laser scanning or experienced; we offer two ways to request a quote.
Many of our clients are relatively new to laser surveying, so we offer comfort and assurance by walking them through the entire process, from pre-planning to the final deliverables. We believe this is why we have had the opportunity to work with some of the best known firms and institutions in the United States.
We know that you have other options when it comes to laser scanning—renting or buying equipment or using a competitor. However, TruePoint offers our clients what many of the other options cannot. Among the many reasons to choose TruePoint are:
BIM stands for Building Information Modeling and is more than just a 3D model. 3D BIM scanning gives engineers the ability to manage the building data throughout its whole life-cycle. It provides accurate spatial relationships and manufacturer details, as well as geographic information and other pertinent aspects of the building.
TruePoint offers high-definition 3D laser scanning for accurately capturing 3-dimensional data in a wide variety of settings, from laser scanning buildings to hospitals or universities to refineries, regardless of size and surface features. We can survey large-scale structures providing you with high definition 3D data quickly. High definition surveying is ideal for digitizing as-built construction and proposed additions or reconstructions. It can also be used to survey large projects during construction, to make sure the design is being executed properly.
Weighing the benefits of laser scanning versus using traditional means to “as-built” a site:
The data collected from laser 3D scanning can produce as-built verification, reality capture and SCAN-to-BIM modeling solutions to support analysis, design, engineering, clash detection and prefabrication.
LIDAR stands for Laser Imaging, Detection, and Ranging (commonly called Light Detection and Ranging). LIDAR is based on a principle referred to as time-of-flight, which uses a pulsed laser that emits the beam, a mirror that deflects the beam towards the scan area, and an optical receiver which detects the laser pulse and reflects it back to the scanner from the object. Time-of-flight refers to using the known speed of light with the amount of time it takes the laser pulse to be emitted, bounce off of an object, and return to the scanner to determine the distance the object is from the scanner (Distance = (Speed of Light x Time of Flight) / 2). LIDAR scanning collects data at a slower rate than phase-based scanners but is able to be used at greater distances than phase-based scanners.
Phase-based scanners emit a constant laser beam into multiple phases and compare the phase shifts of the returned laser energy. The scanner then uses phase-shift algorithms to determine the distance, based on the unique properties of each individual phase (Time of Flight = Phase Shift / (2π x Modulation Frequency)). Although phase-based scanners collect data at a much high rate than time-of-flight scanners, their effective distance is much shorter. Additionally, phase-based scanners tend to have more "noise," or false data, than time-of-flight scanners.
Some projects require special applications due to limitations within the physical setting. Often times this is due to line-of-sight issues and when a scan must be done safely from the ground or with precautionary distance. Some of these applications would include above-ceiling MEP features in hospitals where it is necessary to maintain negative airflow or interstitial spaces that are congested with limited access. Since laser scanning is a non-contact measurement tool (i.e. we can scan from a safe distance or location) this becomes a powerful tool for solving these complex challenges.
TruePoint's clients range from small companies to large nationwide or global firms. TruePoint is ready to mobilize to any site in the U.S., usually within the lead time of only one or two days. Additionally, we have the ability to be on-site short-term or long-term, depending on our clients' needs. We can provide 3D scanning services and 3D laser modeling services.
Data will be captured with industry-leading survey-grade Leica equipment. Leica ScanStations can tie to survey control, achieve 2-4mm accuracy and have real time liquid filled dual axis compensation to help mitigate movement and ensure level scans. TruePoint scan technicians receive formal training from the scanner manufacturer, plus instruction from an experienced scan technician. Our laser scan technicians are highly trained on the following equipment:
We can provide 3D modeling in many formats such as:

Almost any project that requires as-built information can benefit from a laser scanning survey. Talk with our experts and start your 3D laser scanning survey project today.
An as-built model is created from the exact data points collected from the laser scanner. It shows the true representation of the pipes, walls, etc. as they are reality captured. If a wall is not plumb or floor is not level, it will show these exact dimensions. This could be problematic to a professional who needs the best-fit dimensions of a building or room. Conversely, a design model shows the theoretical dimensions of the data captured, meaning the walls or floors are level and meet at 90 degrees. It is easier for architects or engineers to take dimensions from a design model. TruePoint Laser Scanning’s in-house team of CAD technicians and engineers are experts and can help you determine the best type of model for your project.
