Greck was retained by the City of Oshawa to oversee and prepare detailed design plans and provide construction support services for replacement of a twin (4.1 x 2.5) CSPA culvert system crossing under Bermuda Avenue. The preferred solution was to replace the crossing with a twin concrete box culvert system. Detailed design drawings were prepared for construction along with a supporting design brief report that included the hydrologic and hydraulic analyses and evaluation of alternative watercourse crossing designs. Coordination with the design team including a geotechnical engineer, OLS, and utility locates were required. Greck oversaw all required regulatory approvals and permitting along with the preparation of construction documents, tender evaluation and construction inspection.
