The St. Andrews Lock & Dam (SALD), located in Lockport, Manitoba, was constructed in the early 20th century to facilitate commercial navigation from Lake Winnipeg to the City of Winnipeg by drowning the Lister Rapids during the navigation season. The facility is operated and maintained by Public Works and Government Services Canada (PWGSC) and consists of a dam, a navigation lock, a fish ladder, and a two-lane traffic bridge. Most operational features of the dam and lock for navigation purposes remain unchanged from its original opening date.
The dam and traffic bridge are inspected regularly above and below water, according to the PWGSC Dam and Bridge Inspection Policies and Procedures. Following Associated Engineering's success in ranking first in Western Canada on the PWGSC standing offer for Civil Engineering Services, Associated Engineering's Winnipeg office was awarded the 2015 inspection program.
In order to meet the technical requirements and project timelines, delivery of the assignment was a "One Company" collaborative effort led out of the Winnipeg office. Staff from other offices with specific technical expertise related to dam operations, structural/seismic evaluations, and bridge inspections were instrumental in completing the tasks to date and were key in production of the final deliverables.
