3D Laser Scanning

Recognizing the benefits that 3D Scanning could bring to our clients, Westlake was one of the first area firms to offer 3D scanning to augment traditional survey and industrial measurement services. 3D scanning allows us to model virtually anything…ceilings, piping racks, highways, buildings, bridges and ships. We can do this without directly accessing measurement points while providing comprehensive data for site measurement, as-builting and 3D modeling.

Scan data is immediately useful. It is visual and intuitive. The raw scan data looks like a black and white photograph but is actually 3D geometric data that can be dimensioned and used to prepare CAD drawings and models. Clients can view the raw scan data directly on their desktops and take basic dimensions.


3D laser scanning is quick and provides a level of detail that far exceeds conventional surveying. Scanning is completed quickly, reducing impacts to other site activities. It can be completed in the dark, when temperatures are more constant and other site activities are at a minimum.


Data and Deliverables

Westlake’s 3D scanning services offer clients an amazing range of data options. Because all data can be geo-referenced, we can use conventional or GPS surveying control to tie the scan data to a known coordinate system such as a plant grid system or geographical/geodetic control. Data can also be tied to a site or local coordinate system. For example, data from different floors of a building can be tied to a building exterior, or different perspectives of a freeway interchange can be tied to the state plane system. We can provide drawings, dimensions, analysis and renderings to depict true site conditions.

We work strategically with clients to establish project tolerances, define appropriate geometry of a component or structure, and outline both immediate and long-term objectives.

Marine Projects

From fishing vessels to NOAA research ships, scanning captures data for complex hull shapes or entire vessels, enhancing options for design and prefabrication. The result has proven value to clients for cost and time savings.

M/V Island Spirit

For the MV Island Spirit, a small cruise ship, scanning provided detailed data for design and prefabrication of sponson frames so the vessel could cruise Alaskan waters

NOAA Fairweather Sonar Transducer Fairing

Scanning a portion of the hull of the NOAA Fairweather supported design and prefabrication of a new transducer fairing.

Architecture/Historical Preservation Projects

For remodeling, expansion, and historic preservation projects scanning provides data about existing conditions to support analysis, design, and even prefabrication. The data provides visual and geometrically reliable information about every aspect of the building and allows architects, engineers, and contractors to “revisit the site” from their desks whenever the need arises.

U.S. Customs House

Portland, Oregon

From a single scan of the US Customs House in Portland detail was extracted about historic elements including cornices and lamps.

Gilbert Hall on the University of Oregon Campus

Eugene, Oregon

For the University of Oregon’s Gilbert Hall, scanning focused on ceiling structures and was used to validate the BIM model.


Scanning provides data that engineers and planners need for civil project evaluation and design. It offers several advantages. The remote data collection minimizes safety issues and impacts to traffic. In addition, scan data is far more detailed than conventional survey data. The data can be used to generate either 2D or 3D CAD drawings and because it is so visual, it supports public involvement program exhibits, and can be revisited to validate design and construction assumptions throughout the life of the project.

NE Klickitat and 57th Avenue

Portland, Oregon

For the intersection of NE Klickitat and 57th Avenue, 3D laser scanning illustrates the speed and depth of data collected, without impacting traffic flows.

Clackamas River Drive Landslide

Clackamas County, Oregon

3D laser scanning answered the challenge of capturing data for a landslide on Clackamas River Drive. The scan data was overlaid on a traditional topographic map to provide enough detail for the County to create a remediation plan.


When scanning is performed during construction, very detailed and timely data is captured. The speed of data capture means that construction progress is not impacted. For example, as-builts document construction to support future work on-site by showing the location of conduits and rebar. For excavation, shotcreting, grading or rock stockpiles, 3D laser scanning allows detailed and very accurate quantity calculations.

LADD Tower

Portland, Oregon

For LADD Tower in Portland, scan data was used to calculate quantities of shotcrete used, and to identify the wall thicknesses.

Portland Community College, Willow Creek Center

Washington County, Oregon

For a new building at PCC’s Willow Creek Center, scanning captured the location of rebar and conduit prior to concrete pour.


Mechanical Piping

Complex mechanical systems are ideal candidates for 3D laser scanning because conventional measurements are difficult to make and depict. By modeling the scan data, file size is decreased and the data is easier to interpret, especially when color is used to segregate pipe runs. Alternatively, dimensions can be taken in the raw data for pipe dimensions, connection points, and flange detail.

US Army Corps of Engineers Dredge Yaquina

For the  US Army Corps of Engineers Dredge Yaquina, Westlake performed scanning of various engine rooms and piping runs to create a 3D model of the vessel’s propulsion and dredging systems.
