Reality Capture, As-Built & 3D Scanning

EllisDon has been utilizing 3D Scanning Technology, or LiDAR, since 2005 to capture 3D as-built geometry from the field. Since then, this technology has greatly improved in speed, accuracy and accessibility.

We have scanned over 10 million square feet, across hundreds of projects ranging from heavy civil infrastructure to existing mechanical rooms and historic heritage projects. We have converted trillions of 3D points to BIM using a variety of specialized computer systems and processes. Architects and Engineers have benefited from obtaining reliable information on existing buildings, reducing the time required to chase systems as well as understanding the actual site conditions. We also regularly use LiDAR to scan roadways and understand the exact geometry of surfaces so that we are able to coordinate the design of the new road system with literal pin-point accuracy and an extensive understanding of critical quantities that can make or break the project budget.

What We've Done

Canada Permanent Trust Building, Toronto, Ontario

Scan-to-BIM Project

The exterior and interior of this Neo-Gothic style structure in the heart of downtown Toronto was laser scanned with the intention of producing up-to-date structural and architectural as-built models by our team. Designed by Canadian architect Henry Sproatt, the 18-floor office building was built between 1928 and 1930, and so accurate documentation of the existing conditions became necessary for the client’s facility managers to continue doing their work effectively. The timely production of detailed as-built models for historical buildings is made easier with our utilization of reality capture technologies. 

Toronto Western Hospital, Toronto, Ontario

Laser Scanning

Our specialists were sent in to conduct laser scanning in the basement corridors of the Toronto Western Hospital and provide accurate data capture of existing piping systems located at exposed and above ceiling environments. Various confined mechanical rooms were also captured by our scanning team. Feature-detecting modelling software was then used to model the systems for coordination with Smith + Andersen.

Private Residence, Dundas, Ontario

Scan-to-BIM Project

A surveying specialist was deployed to perform laser scanning of this 6 acre property located in Dundas, Ontario. Our specialist laser scanned the area and created a point cloud deliverable which was subsequently divided into three pieces through careful isolation and post-processing in the office. A landscape/topography isolation of the point cloud was created by cropping the captured trees and vegetation, which was then used to create a topography surface complete with highly accurate contour lines. The buildings and minor structures on the property were also isolated for the purposes of producing an accurate 3D model. All processes and production of deliverables were done in-house.

Laser Scanning 

Our Geodetics team data captured twin bridges of Highway 400 that are approximately 1.5 km in total length and 20 meters apart. The four bridges are located just south of Lock 45 in Port Severn, and were laser scanned to capture the top, underside and structural members. A final cleaned point cloud was then delivered to the client in a timely manner.

Yorkdale West Expansion, Toronto, Ontario 

Laser Scanning 

Certain areas within the Yorkdale Mall Sears site were laser scanned by our specialists during the building expansion in 2014. The scanning was conducted to capture visible building information at ground and second levels including above ceiling space. The specific areas of interest were where structural steel was to remain or be retrofitted for the expansion.

Railway As-Built Verification

Laser Scanning 

Our team of surveying specialists laser scanned a portion of railway. The stretch of railway is approximately 870 meters in length and 150 meters in width. The majority of scans occurred at track level to accurately capture the railway tracks, topography, structure and underside of bridges. A registered and cleaned point cloud was then delivered to our client along with a fly-through visualization file.

 

Calgary International Airport, Calgary, Airport

Scan-to-BIM Project 

For the Calgary International Airport the connectivity corridor was scanned in the area of development by our laser scanning specialists to capture its existing conditions.
