CROSSTOWN LRT WHO IS METROLINX? Construction of the Eglinton Crosstown LRT Line Background • In September 2008, Metrolinx launched a regional transportation plan – a 25-year, $50 billion plan -- to coordinate and integrate transportation and transit in the Greater Toronto Area • In 2010, City of Toronto approved the project to build the Eglinton Crosstown from Weston Road in the west to Kennedy Station in the east. • Following a competitive process, Crosslinx Transit Solutions (CTS) was awarded a contract in July 2015 to design, build, finance, and maintain the Eglinton Crosstown Light Rail Transit (LRT). Project Players and Roles What Are We Building – a New Modern LRT • 15 underground stations and 10 surface stops – 9 km below ground and 10 km above ground • A maintenance and storage facility • A 19-kilometre route separated from regular traffic • Transit communications system • Links to 54 bus routes, three subway stations, GO Transit, and a new UP Express station Safety First – Our #1 Priority We train and direct staff to: • Always have a site specific safety plan and site specific emergency plan. • Ensure pre-work hazard assessments are complete and understood. • Ensure job hazards analyses are complete and understood. • Do everything possible to protect themselves, co-workers, and members of the public. • Stop work if the safety of themselves, co-workers and members of the public cannot be assured. • Identify and report unsafe behaviour and coach each other to make improvements. • Be prepared and equipped to work safely. Crosstown Design Approach Street Level – Contextual and An International Signature for Entrance – Bright & Secure Inviting Toronto Concourse – Simple & Pristine Concourse – Transparent & Open Platform – Spacious & Animated Accessibility Station and Stops are designed to be universally accessible, including satisfaction of the AODA, applicable City of Toronto Guidelines, the OBC, and CSA Standards. Some of those features include: • Barrier-free paths from the entrance level to the station platform level • Tactile warning strips and tactile walking surface indicators • Signage systems with tactile indicators • Passenger Assistance Intercoms (PAI) • Low floor Light Rail Vehicles (LRV) with designated wheelchair locations • Nominal gaps from platform edges to LRV entries • Automated visual and audible stop announcements • On-street and off-street paratransit passenger pick-ups and drop-offs Environment & Sustainability During Construction • Programs to minimize impact on wildlife, their habitats, watercourses and trees • Reduce impact on our community neighbours through the management of dust, noise and vibration • Sustainable construction practices, including active management of construction and demolition generated wastes, targeting 75% waste diversion from landfills; and off-site beneficial reuse of excess soil. Project Design Sustainability • Project wide application of Toronto • Fritted glazing (minimize bird Green Standard collisions) • LEED Certification at EMSF • Shielded exterior lighting (prevent off- • Bike parking for short- and long-term site light trespass) users • Sheltered waiting areas • Dedicated pedestrian routes • Energy efficiency – LED lighting, heat • High Solar Reflectance Index paving recovery systems • Green roofs • Landscaping – use of native, drought- • Water use conservation/efficiency tolerant plants and large trees How We’re Building the Crosstown: Construction Overview How We’re Building: Two Methods Cut-and-Cover Stations Mined Stations • An area the size of the station’s • Mining occurs from inside of the footprint is cut, a shallow area excavated entrances after the excavated, and steel piles, braces, and shoring is complete.

The first stage is support of excavation. • Support of excavation (shoring) is a common step in the process of installing the foundation of a building. • In the first stage, crews will install steel piles around the perimeter of the entrance. This has been completed at both entrances. • In the second stage, crews excavate the area level by level, installing braces and tie-backs as they progress. This work is underway at both entrances. How We’re Building Avenue Station: Sequential Excavation Mining Method • Mining occurs from inside of the excavated entrances after the support of excavation is complete. • The underground area to be excavated is divided into manageable segments and the segments are excavated in a planned sequence. • Within the mined area, the station box is constructed accommodating the rail tunnels, associated platform and rail infrastructure. • Avenue station has one of the longest station areas with approximately 400m to be mined. This is to accommodate a turn-back area and special track works. Avenue Long Term Closure Summer 2016-2020 Support Works - Dewatering • The term “dewatering” means pumping from the ground water at a site where there will be excavation. • At Eglinton Avenue West and Avenue Road, dozens of small wells will be drilled around the entire station box where excavation will be taking place. • The volume of soil that requires dewatering is significant. • System will operate for the duration of construction (2020). Support Works - Dewatering • 72 wells will be drilled approximately every 10 metres and shallow trenches will be required to lay the pipes, pumps, wells and valves to do the work. • The drills installing the wells and the trenches for the piping will encircle the station box. • Installation work will occur between May 2017 and Fall 2017. Support Works – Dewatering • Four dewatering wells are required to be installed in Eglinton Park. • Wells are to the west of the pedestrian pathway. • Tree protection will be installed during the works; no trees will be injured or removed. • Pedestrian pathway through the park will be maintained during the works. Support Works – Utilities Mitigation What to expect: Sewer Lining • Sewer lining is a process intended to increase the durability of the sewers. • A section of the sewer system is cleaned and vacuumed and a CCTV inspection is completed. Then a liner is inserted into the sewer section from within the maintenance holes • The process is designed to be generally non-disruptive and eliminates the need for excavation of the entire sewer section. • Maintenance holes that will be accessed are located on Eglinton Avenue West between Braemar Avenue and Lascelles Boulevard. • Lane closures will be required for this work. Pedestrian access will be maintained. • Above ground pipes will be in place between maintenance holes to bypass pump around the sewer lines during the liner installation. • Due to the nature of the work, an unpleasant chemical odour may be noticeable
