INNOVATION May-June 2019

1515 DOUGLAS STREET, VICTORIA BC The 20-metre diameter glass rotunda roof at the six-storey 1515 Douglas office development across from City Hall in Victoria, provided an opportunity to develop a unique structural and architectural solution. Read Jones Christoffersen Ltd. engineers worked with D’Ambrosio Architecture + Urbanism to develop options and build three scale models. The selected option—which minimized material and optimized daylight transmission—is a composite structure consisting of six “boomerang”-shaped glulam members supported by tension rods, and steel tension and compression rings. Concealed steel dowels connect the horizontal and vertical glulam members of each “boomerang”, and custom steel fabrications at each node connect the tension rods to the composite structure. Participants: Jawl Enterprises (owner), Read Jones Christoffersen, D’Ambrosio Architecture + Urbanism, Applied Engineering Solutions, Campbell Construction, and StructureCraft Builders.

EASYMAP MR MIXED REALITY MAPPING As a geologist or geotechnical engineer, imagine using augmented visual powers to automatically measure surface orientations, and drawing your geological interpretation directly onto the rock face using virtual painting tools. The system gives the user the ability to see all previously captured relevant mapping and drilling data during mapping, or map onto high- resolution scanned virtual rock faces. Mixed reality technology is changing best practices in data collection and analysis, not just visualization and communication. Interpretation is enhanced by data rich visualization and is already 3-D spatially referenced to import directly into modelling software. The EasyMap MR software application is designed and field tested for use with the Microsoft HoloLens headset that incorporates 3-D scanning and holographic projection technology. Product development: Dr. Emre Onsel and Prof. Doug Stead, P.Eng., (Simon Fraser University), in a Mitacs-funded partnership with Dr. Wayne Barnett, P.Geo., and Dr. Luca Zorzi (SRK Consulting)

RUSHBROOK TRAIL Closed in 2001 for safety reasons, the Rushbrook Trail in Prince Rupert was one of the few access points to Prince Rupert’s waterfront. Seeing the need to re-open this community trail, the Prince Rupert Rotary Club began the re-design process and raised the capital funds for the project. In early 2017, McElhanney assisted the rotary club with the tendering, and subsequent contract administration for the reconstructed trail. The project included the installation of six lock block catchment walls, construction of 1.2 kilometers of new trail, and the installation of three, pre-fabricated aluminum span bridges over the Prince Rupert Harbour. Since re- opening in the Summer of 2018, the trail has garnered positive reviews and been well-used by the community. Owner: Kaien Island Trail Enhancement and Recreation Society. Participants: Sandra Penner, P.Eng., Sean Carlson, EIT, Craig Dusel, P.Eng.
