Engineering Survey of the Vancouver Public Library, Central Branch

McElhanney was retained in 2017 by local construction contractor Smith Bros & Wilson (SBW) to provide surveying services to aid renovations at the library, which included the addition of escalators, elevators, and an auditorium. The objective of the survey was to identify a precise location for a temporary concrete platform supporting a multi-storey crane, and to identify positions to underpin and support the load of the crane and platform sited at street level on an underground parking structure. Both firms knew the complex nature of the existing utilities in the parkade structure would require an innovative approach to data collection and presentation.
