Project Overview

Structural consultant for the Greater Toronto Airport Authority (GTAA), MTE conducted multiple inspections of the Link Train’s guideway structure and support system to identify structural deficiencies and potential safety concerns. To ensure thorough and accurate results, our inspection team accessed the guideway structure of one train system using a maintenance vehicle while the other system remained operational. A comprehensive visual evaluation of the guideway’s structural integrity, MTE examined the train’s 53 supporting concrete piers, which are crucial for its performance and safety. We developed crack repair procedures for the piers’ surfaces and grout restoration techniques for the areas under the bearing plates. We supervised the repair of each pier during the construction phase.

MTE’s Involvement

MTE organized a detailed visual condition survey of the APM-Link Train steel superstructure over Airport Road in 2007, 2008, 2010, 2012 and 2016. We also completed a comprehensive survey of the train’s steel guideway and concrete piers in 2009 and 2016.
