Gardiner Expressway

2014
Morrison Hershfield
This project consisted of: Geomatics, Mapping, Surveyors

TULLOCH was contracted by Morrison Hershfield in 2014 for a 3 km engineering survey of the Gardiner Expressway, Lakeshore Blvd, and all of the crossing roads.  This survey was commissioned to support the detail design of the rehabilitation of the Gardiner between Park Lawn Avenue and Ellis Avenue.

Mobile LiDAR was used to collect all of the required topographic data in 24 hours, and base plans were delivered to Morrison Hershfield in less than two weeks.  This technology was selected by the City of Toronto, as it allowed the survey to be completed without closing any lanes on the Gardiner.  The deliverables were submitted as Bentley Microstation CAD files.

In the construction phase of the project, the Gardiner Expressway was closed for the resurfacing of the three bridge structures. During this phase, Morrison Hershfield contacted TULLOCH on short notice to  perform quality control checks on proposed cut/fill layouts across the three bridge decks near Park Lawn Avenue.

Two crews were mobilized within eight hours to  capture information related to the asphalt removal prior to re-surfacing, as well as the newly laid asphalt, all for the purpose of determining asphalt volumes.

This was a clear demonstration of TULLOCH’s ability to mobilize its survey crews and prepare deliverables within very tight timeframes when needed. The required forensic data and As-built surveys were delivered to Morrison Hershfield within one week of the field survey.
