Real-time deformation and vibration monitoring for a large urban project surrounded by existing critical infrastructure in the historic LeBreton Flats area in Ottawa
Hugh Gillen, Shane Dunstan
In the proceedings of: GeoNiagara 2021: 74th Canadian Geotechnical Conference; 14th joint with IAH-CNCABSTRACT: The Ottawa Public Library - Library & Archives Canada (OPL-LAC) Joint Facility is a new urban building project in the historic LeBreton Flats area of Ottawa, Ontario. The early site works encompass mass excavation and site preparation. A monitoring program is currently in place to help protect existing critical infrastructure surrounding the site against adverse impacts during construction. The monitoring program includes survey points and vibration monitors along an electrical duct bank and high pressure watermain, an automated remote tunnel profile monitoring system and vibration monitor in an LRT tunnel, and borehole vibration monitors above two large utility storage tunnels in rock. Except for the conventional survey points, all other monitoring is being completed remotely with automated alarms and in real-time. Programs such as this are expected to help mitigate construction risk while navigating complex projects. This paper presents an overview of the applied methodologies and discusses some of the data, challenges, and benefits of the program.
RÉSUMÉ: L’installation partagée de la Bibliothèque publique d’Ottawa et de Bibliothèque et Archives Canada (BPO-BAC) est un projet de construction urbain aux plaines LeBreton à Ottawa, Ontario. Le contrat inclus excavation en masse et préparation du site. Un programme de contrôle est en place pour protéger l’infrastructure critique environnant contre impacts adverses pendant construction. Le programme inclus des points de levé et des capteurs de vibrations au long d’une conduite de hydro et d’alimentation en eau, un système de contrôle distante du profil d’un tunnel TLR, et des capteurs de vibrations en forages au-dessus de deux tunnels de services publics. Excluant l’arpentage des points de levé, le programme se fasse compléter à distance avec des alarmes automatiques et au temps réel. Des programmes de contrôle, comme ceci, sont anticipées à réduire le risque de construction en navigant des projets complexes. Ce papier présente un sommaire des méthodologies et discutes des données, difficultés, et avantages du programme.
