What is 3D scanning?

3d laser scanners use light and radar (LIDAR) to measure and record precise locations and distances, captured as data points. The acquired data is used to generate a point cloud. Highly accurate 3D digital models are produced using software packages such as Revit and BIM 360. 3D laser scanning is a revolutionary tool to document existing conditions in construction, insurance, engineering and property management. 3D models generated from these point clouds expedite design, planning, prefabrication, asset management, and facility modifications.

What’s the process VTS uses for 3D scanning?

The first step is for VTS to understand each client’s application and needs. That determines which type of equipment should be used for each project’s needs. Scans are taken in multiple positions around a site from varying viewpoints. Laser scanners send light pulses at high speeds which reflect off objects and return to the scanners’ sensor. For each pulse, the distance between the scanner and object is measured by determining the elapsed time between the sent and received pulses. Each point of the scan is converted to a pixel with a known x-, y- and z- coordinate. Millions of data points are captured and processed into a point cloud, creating an accurate data set of the structure or site.

What kind of camera and equipment are needed?

Before selecting equipment, VTS needs to understand the purpose of the digital representation and data . We must know exactly what the data will be required to do. No property or incident is alike. There isn’t a “one size fits all” solution, or a universal 3D camera. The equipment in our tool chest includes imaging capture, 360 or panoramic captures, structured light devices, SLAM devices, lidar laser scanners, drones, and vehicle based equipment. 360pro and 360consultant services enable our customers to get the benefits of collaboration and accuracy of 3D capture, without having to invest in 3D laser scanning equipment. When our capture crew is on a site, they use the specific equipment needed for each use case.

How much does it cost to get a 3D model?

Each project is individual and customized with a mix of technologies used to create the specific outcomes needed at the best value. The first question we ask is to understand the purpose of the 3D model or virtual tour. No two properties or projects are exactly the same. The type of equipment and time needed for data capture depends on the Level of Detail required.

What is "level of detail" or LOD?

LOD is described in levels such as 100, 200, 300 and 400. The more accurate the application needs to be, the higher the level of detail. Equipment is selected based on the LOD and the scope of the building or property to be captured. Our quotation includes the time required for our capture experts to collect the data on site, the LOD, and the time to convert the data into a point cloud and a 3D model or digital twin.

• LOD 100 captures structural grids, levels, exterior walls, interior walls, floors, exposed structure, ceilings, roofs, rooms, and spaces. Applications that fall in the category of LOD 100 include: planning, building context, massing and rights of light studies.

• LOD 200 captures level 1 assemblies such as fire rated assemblies, exterior & interior doors & windows, storefront, vertical and circulation. Applications that fall in the category of LOD 200 include: primary structural layout, Strip outs and refurbishing.

• LOD 300 to 500 adds details such as millwork & caseworks, toilet partitions & fixtures, wall & ceiling devices, diffusers, sprinklers, lighting and large MEP equipment. Applications that fall in the category of LOD 300 and above include: standard surveys, space planning, general analysis, detailed surveys, fabrication purposes, settlement, monitoring, visualizations, FM and asset identification.

What is a digital twin?

A Digital Twin is the exact representation of, for example, a building or manufacturing facility. Digital twin refers to a digital replica of physical assets, processes and systems. Imagine a 3D model that has a built-in record of designs, systems and dimensions.

What is a virtual tour?

A virtual tour is a simulation of an existing location, usually composed of a sequence of videos or still images. Also known as 3D tours or 3D walkthroughs, allow viewers to digitally tour a building or property as if they were there. 3D virtual tour technology has been increasingly used in the documentation and preservation of historic properties that are at risk of being razed or undergoing restricted public access. VTS virtual tours include dimensions, birds eye views and the ability to see photos and documentation.

What is BIM?

BIM stands for Building Information Modeling. Building information modeling (BIM) is a process involving the generation and management of digital representations of physical and functional characteristics of places. BIM gives engineers the ability to manage building data throughout its life-cycle. It provides accurate spatial relationships and manufacturer details, as well as geographic information and other pertinent aspects of the building.

What industries does VTS serve?

3D laser scanning is indispensable in dealing with buildings, cities and structures. VTS 360Access specilaizes in vertical data capture for telecom, wireless and utility industries. The data gleaned from scans provides critical information for uprades, design, and prefabrication. VTS 360Pro, 3D Laser scanning, is ideal for municipalities, industrial manufacturing, energy and wastewater treatment facilities. 3D scans provide precision and detail in complex buildings and in facilities where there may be a lot of HVAC equipment, pumps, motors, beams, boilers, or other equipment. Visual capture of equipment and systems in relation to the rest of the environment is essential for simulations, planning and construction. Long range scanning is helpful for the mapping and modeling of proposed implementation sites of towers or telephone lines. VTS 360consultant delivers expedited insurance claims, appraisals and readiness planning for insurers and property owners.

Why should you trust VTS with 3D services?

Many of our clients are relatively new to 3D scans and digital twins. We detail the entire process, from pre-planning to the final deliverables. Some of the best known and recommended telecom and construction firms look to VTS for 3D services. Each project is centered on meeting your needs and delivering the 3D solution that meets the client deliverables.
