Over the past century, HH Angus, one of Canada's largest private engineering firms, has been providing consulting services in the healthcare, institutional, commercial, education, transportation and industrial sectors, along with a deep portfolio of work in energy generation/distribution, technology and sustainability.
As HH Angus commenced work on a multi-year project at Toronto Western Hospital to refurbish and replace mechanical, electrical, and plumbing (MEP) systems in the central powerhouse, the engineering firm wanted to gain efficiencies in building information modeling (BIM) processes.
By investing in the Matterport Pro2 Camera to scan mechanical facilities, HH Angus was able to import 3D spaces into Autodesk Recap Pro and Revit to analyze MEP equipment and model future phases of the facility.
HH Angus reduced the cost of site surveys by half, replacing traditional survey methods with 3D scanning. The team used the Matterport Pro2 camera to capture mechanical facilities at Toronto Western Hospital, scanning 17,500 square feet of the site. The team dramatically reduced repeat site visits, referring designers, engineers, and stakeholders to the Matterport 3D models throughout the project lifecycle.
“With Matterport, we’ve eliminated the need for 2D photographs, which demanded significant time to organize and lacked the complete context of the facility that we needed.” Melissa Parry, BIM Specialist at HH Angus said. “Matterport 3D spaces enable us document as-built conditions, validate models, and design faster than ever before.”
HH Angus imported an .xyz point cloud file of the Matterport 3D model into Autodesk Recap Pro. “We organized points into regions to enable designers to toggle the visibility of different parts of the point cloud while working in Revit,” Parry said. “We saved regions into separate point cloud files for linking into Revit, which is essential for Revit model performance.”
The team created worksets, used origin-to-origin positioning, and applied phasing and alignment of the point cloud before modeling future phases of the MEP facility in Revit.
Because the Toronto Western Hospital project required a high volume of Revit families created in a short amount of time with limited information, HH Angus relied heavily on the Matterport 3D models for equipment identification, measurements, and collaboration.
The team used Matterport workshop tools to take measurements and obtain MEP equipment dimensions. “We relied on “Mattertags” to annotate the MEP space in one central, shared location, which helped the team collaborate with stakeholders more effectively,” Parry said. “Documenting data, Revit family names, and family type within the Matterport 3D models helped our designers review the latest equipment tags and references while modeling in Revit.”
