Markham Culvert Repairs
Greck were retained by the City of Markham to assist with the preparation of detail design drawings for the repair and retrofit of five culvert crossings throughout the City. Greck undertook a hydraulic analysis for each crossing to identify options for hydraulic improvement. Greck worked together with the City and the retained structural engineer to determine the preferred option and to assist in the preparation of detail design drawings for construction. Erosion and Sediment Control plans were prepared to support dewatering operations and a phased construction approach to accommodate in-water works.
