ABSTRACT: The Toronto-York Spadina Subway Extension Project (TYSSE) is the first subway extension that crosses Toronto borders and connects the City of Vaughan (York Region) to the existing Toronto Transit Commission™s (TTC) system in the City of Toronto. A challenge with the TYSSE project is managing a schedule that requires completion of the geotechnical investigations concurrent with the design phases. Management strategies included the development of a geo-engineering team comprised of TYSSE, a principal consultant, and two field consultants, division of field investigations into two phases to correspond with the design schedule, and development of an efficient work flow and content management system accessible by internal and external users. These strategies resulted in meeting the TYSSE project schedule and completion of 1080 boreholes, 21,900 metres drilled, and 192 reports in less than the proposed 2.5-year investigation schedule.
RÉSUMÉ: Le projet du metro «Toronto-York Spadina Subway Extension» (TYSSE) est le premier projet de prolongement du metro qui traverse les frontières de Toronto et relie la ville de Vaughan dans la region de York au système existant de la ville de Toronto «Toronto Transit Commission» (TTC). Un defi posé par ce projet est la gestion du calendrier en vue de completer les investigations coincident avec les phases de conception. Les strategies mis en place on inclus le developpement d™une équipe de géo-ingénierie, composé de TYSSE, un consultant principal et deux consultants-technique de terrain, des multiples de phases de l™enquête de terrain pour compléter le calendrier de conception et un flux de travail efficace et un système de gestion de contenu spécifique au géo-ingénierie disponible à tous les membres du projet. Les strategy ont permis la rencontre du calendrier et la réalisation de 1080 forages, 21.900 mètres forés et 192 rapports en moins 2.5 ans avant de l™enquête du calendrier proposé.
