AEI was selected as the preferred proponent for the replacement design and contract administration for three (3) culverts located in Oshawa, ON.

City of Oshawa Culvert Renewals

The existing Otter Creek Bridge consisted of a deteriorated concrete superstructure, which required a sensible and practical replacement. AEI's scope of work included all field investigation works, coordination of topographic surveys, geotechnical investigations, and underwater investigations. As part of the superstructure replacement design, existing foundations were to remain but required rehabilitation to ensure the structure was compliant with current codes.

AEI's scope of work included a topographic survey, geotechnical investigation, hydrological assessments.
