Laser scanning has become a preferred method for gathering measurements for as-built documentation of unusual or complex structures. Typically serving architects, engineers and contractors, Coast 2 Coast‘s professionally trained Field Survey Specialists use HDS in a variety of environments that require 3D scanning services, and have multiple types of HDS systems to work with depending on the nature of the project and field conditions.
The laser scanning systems capture millions of data points in hard to reach or dangerous spaces with 6mm or better accuracy without any safety hazards. This creates a high density point cloud, and digital photo images are typically used in conjunction with other as-built or existing conditions documentation before using converting services to develop 2D drawings or locations 3D models. Also, high-definition laser scans are now commonly being used as a basis for the development of BIM initiatives for use in design and construction projects. By starting with higher quality field data, clients can expect a better design and reduced construction risks.
Benefits
Always pushing the technological envelope, Coast 2 Coast uses the latest advancements in cutting-edge geospatial 3D laser scanning tools and 3D software platforms to deliver precise existing conditions documentation services.
Whether your needs for laser scanning services include as-built details for a historical renovation, subsurface imaging to map the location of underground utilities, or pinpoint accuracy in locating structures for GIS applications, Coast 2 Coast is distinctively positioned to implement a variety of advanced geospatial services such as 3D laser scanning to accommodate the needs of most any project. Regardless of location or complexity, Coast 2 Coast can provide 3D scanning solutions that meet both your program objectives, as well as, your budget.
Challenges
While detailed information is a good thing, 3D scan results require our in-house staff to analyze every detail of the building when, per project scope, they often only need a fraction of the information.
As a client you can be fooled into the fact that, if you are missing data, a laser scanning survey of that missing area will gather the rest of the information you need for complete documentation. What these firms don’t consider is the potential human error involved in both scanning and graphing points into the model, especially when trying to coordinate with older plans.
If the client needs as-built plans gathered and drawn from scratch, and they request that measurements be gathered entirely by laser scanning, the cost rises exponentially. This is unnecessary and, especially with the 100 percent specification, it’s impractical.
For example, the lower level measurements within a mechanical room are easy and useful to get with a laser scanner. However, to get the upper side of the room, the equipment has to get above the ceiling and be able to move to obtain all visible areas for accurate documentation. You can imagine the difficulty with above ceiling scanning, and therefore, the laser scanner is not appropriate for this kind of situation.
Solutions
With these realities in mind, there are alternative measuring devices that pair well with laser scanning to deliver the full set of building documentation. Coast 2 Coast’s depth of experience in this field has allowed us to evaluate unique situations and accommodate them with our best practices and combination of tools to fit the project at hand. We’ll use the technology needed to produce an accurate model, with or without the laser scanner.
Talk to Coast 2 Coast about your as-built documentation and laser scanning needs, because we’ll use the technology to the level that is necessary, and provide alternate solutions for the remainder of the project.
