STM’s Underground Garage near the Côte-Vertu Metro station in Montréal earns Envision Platinum for Sustainable Infrastructure

–French Translation Follows–

The Garage souterrain pour voitures de métro a proximité de la station Côte-Vertu (Côte-Vertu garage) project was conceptualized in response to a need for an accessible location to maintain and park trains while relieving mounting pressure on a busy and growing metro network. The underground garage comprises a 10-story building that includes a track for trains to circulate from the Côte-Vertu station to the garage, a large area with a network of tracks to divert trains once they arrive, and three underground tunnels, including two tunnels to park and one to maintain trains.

The goals of the project are to:

• Provide a parking area for trains
• Increase the capacity of the metro network, enabling the addition of trains on the Orange line, thereby increasing service frequency during rush hour
• Support the anticipated growth of the metro network over the next ten years
• Ensure enough capacity for the eventual expansion of the Blue line.

Le projet de garage souterrain pour voitures de métro (Garage Côte-Vertu) de la Société de transport de Montréal (STM), a été conçu en réponse à plusieurs besoins dont celui d’avoir un endroit accessible pour entretenir les trains et celui d’équilibrer les espaces de stationnement aux extrémités de la ligne desservie. Situé à proximité de la station Côte-Vertu, il permettra une plus grande fréquence de passages afin de soulager la pression croissante sur une ligne de métro déjà chargée. Le garage Côte-Vertu est constitué de trois bâtiments de surface, dont un bâtiment de dix étages qui plonge sous terre jusqu’aux tunnels pour y loger un atelier d’entretien. Le projet comporte aussi une voie de raccordement pour que les trains puissent accéder au garage à partir de la station terminale Côte-Vertu et un imposant faisceau avec plusieurs appareils de voies pour guider les trains vers l’un des trois tunnels.

Les objectifs du projet sont de:

• Ajouter dix espaces de stationnement pour les trains du métro ;
• Augmenter la capacité du réseau de métro avec l’ajout de trains sur la ligne orange ce qui accroitra la fréquence de service jusqu’à 25 % aux heures de pointe ;

• Soutenir la croissance de l’achalandage prévue pour les prochaines années;
• Augmenter l’offre de service en vue du prolongement de la ligne bleue.

One of the most important ISI podcasts of the year! On October 13, at 12:30 pm ET, we will talk  about capturing and removing carbon dioxide and combating climate change. This “Sustain it or Explain it” (SOE) #LinkedInlive video podcast will educate participants about the current and evolving landscape of carbon dioxide removal applications and innovation, especially as it applies to civil infrastructure. The podcast discussion will also provide insights into alternative, peer-based methods of activism, advocacy, and impact, and feature opportunities for participation. Chris Neidl, co-founder of the OpenAir Collective, will join us to discuss how you can make a difference!

OpenAir is a GLOBAL VOLUNTEER NETWORK that is accelerating carbon dioxide removal advancement through collaborative member-driven advocacy and R&D.

In this live video podcast, Neidl will provide an overview the collective’s growing activities, the critical necessity of carbon removal as a component of any effective response to the climate emergency, and how distributed networks and volunteer open-source production is driving real world change.

Envision Sustainability Professionals (ENV SPs) are encouraged to engage in the conversation and join the OpenAir community, if they care about carbon dioxide removal.

This podcast will also identify key technology-and-policy trends that are driving change when it comes to carbon removal in the architecture, engineering, and construction(a/e/c) industry.

Date & Time: October 13 at 9:30 PT, 10:30 MT, 11:30 am CT, 12:30 pm ET, 1:30 pm Atlantic time.

The Sunset and Heathfield Pump Stations and related force main pipes sends sewage from Sammamish, Issaquah, and Bellevue to be cleaned at King County Wastewater Treatment Division’s (WTD) South Treatment Plant in Renton, Washington. For nearly 50 years, these stations served the area reliably but were reaching their operational limits. The goal of the project was to upgrade the Sunset and Heathfield pump stations and the connected force main pipe to ensure WTD can continue serving a growing population for many more years to come.

King County selected the Envision framework for this project due to its comprehensive nature and relevance to an industrial infrastructure project. The Envision rating system encourages sustainable, equitable, and resilient design, construction, operations, and maintenance processes and practices throughout a project’s lifecycle.

King County WTD staff led the Envision submission for this project and worked closely with Stantec Consulting, the prime architecture and engineering firm.
