INNOVATION May-June 2018

3-D RE-CREATION OF FINE ART PAINTINGS + Using technology originally used to scan the Mona Lisa , Arius Technology has developed a 3-D colour-scanning system using low-power red, green, and blue lasers. It produces 3-D full-colour printed reproductions of fine art that re-create the minute details of each brush stroke down to a scale of about 10 microns (a tenth the width of a human hair). The disciplines involved include mechanical, electrical, computer, and software engineering, supported by team members with professional art credentials. Arius Technology has just completed its second painting scanning project at Tate in London, has placed a scanning system for private collectors at a freeport art storage facility in Europe, and has plans to do the same in Asia starting with a private collector in Hong Kong. It is also launching a platform for contemporary art creation under its new brand, alta™. Mike Jackson, P.Eng., Ken Dyck, P.Eng. Seven critical sections (totaling 770 metres) of 375-millimetre-diameter PVC sanitary sewer were operating at capacity and with many developments occurring upstream, the City of Maple Ridge had an immediate need to upsize them. Because the sanitary sewer runs through an environmentally sensitive area (the shore of Kanaka Creek, Metro Vancouver’s Kanaka Creek Regional Park, and a green belt) and the area has a high water table, open-cut replacement was not feasible and pipe-bursting technology was chosen. The equipment used to pull in the new 865-millimetre high-density polyethylene (HDPE) pipe was the Grundoburst 2500G Static Pipe Bursting Rig, which has a maximum of 310 tons of pull force. Owner: City of Maple Ridge. Design and Contract Administration: Velimir Stetin, P.Eng. (City of Maple Ridge). Contractor: PW Trenchless Construction.
