Form Revised: February 2005 TORONTO TRANSIT COMMISSION REPORT NO. MEETING DATE: August 23, 2010 SUBJECT: TORONTO-YORK SPADINA SUBWAY EXTENSION PROJECT VAUGHAN CORPORATE CENTRE STATION APPROVAL OF FINISHES AND ARTWORK ACTION ITEM RECOMMENDATION It is recommended that the Commission approve the final design, finishes, and artwork for Vaughan Corporate Centre Station, which will be presented through the public consultation process. FUNDING Sufficient funds for this expenditure are included in the Toronto-York Spadina Subway Extension (TYSSE) Project, as set out on pages 1439 to 1442 of the TTC 2010-2014 Capital Program (Category - Expansion) which was approved by City Council on December 8, 2009. BACKGROUND The TTC is planning the design and construction of an underground subway line from the existing Downsview Station on the Spadina Line located in the City of Toronto, to the proposed Vaughan Metropolitan Centre located in the City of Vaughan, Region of York as shown in Exhibit 1. The new 8.6 km long line will include both tunnelled and cut and cover sections. The Toronto-York Spadina Subway Extension (TYSSE) project is being funded by the Government of Canada, the Province of Ontario, the City of Toronto, and the Regional Municipality of York. The TTC is managing the design and construction of the TYSSE project and will own and operate the subway extension. At the Commission meeting of October 23, 2008, Contract A85-75C for the design of Vaughan Corporate Centre (VCC) Station was awarded to the design team lead by Arup Canada Inc. The architectural firm for this team is Grimshaw Architects. At its meeting of September 24, 2009, the Commission approved the TYSSE Station Design Philosophy with additional emphasis on achieving high quality architecture, urban design, streetscape, and landscape architecture as follows:
TORONTO-YORK SPADINA SUBWAY EXTENSION PROJECT VAUGHAN CORPORATE CENTRE STATION APPROVAL OF FINISHES AND ARTWORK Page 2 Integrated design of all elements with strong aesthetics and public artwork; Column-free structures wherever possible with high ceilings and simple flow of space; Bright, open spaces with daylight penetrating deep into stations where possible; Barrier-free with at least one fully accessible entrance; Use of TTC standard elements; and Sustainable design to meet Toronto Green Standard. At the Commission meeting of December 16, 2009, the Commission approved the conceptual design for this station. The project has been reviewed by the public and all stakeholders; including staff from York Region and the City of Vaughan. DISCUSSION DESIGN: Exhibit 1 TYSSE Map Exhibit 2 Aerial View on Opening Day Exhibit 3 Aerial View with Future Development Exhibit 4 Site Plan on Opening Day Exhibit 5 Site Plan with Future Development VCC Station is located north of Highway 7 to the west side of the relocated Millway Avenue. The station will have a tail track structure extending north of the station box and a crossover box extending south of the station underneath Highway 7. The VCC Station will be a multi-modal transportation hub with an on street Passenger Pick Up and Drop Off (PPUDO), and connections to York Region Transit (YRT) Bus Terminal and to Viva Bus Transit running along Highway 7. The YRT bus terminal and PPUDO will be owned and maintained entirely by York Region, and are currently under development by YRRTC. The station design consultant has worked through a value engineering exercise to reduce costs, producing several revised designs which were reviewed with YRRTC and resulted in a revised conceptual design at a significantly lower cost. The VCC Station project incorporates the following environmental initiatives: Cool roof to main entrance; Green roof to electrical substation; Increased daylight levels to reduce electric lighting power usage; LED lighting in pylon signs, and energy efficient lighting in illuminated wayfinding signage to reduce power consumption; Water efficient plumbing fixtures;
TORONTO-YORK SPADINA SUBWAY EXTENSION PROJECT VAUGHAN CORPORATE CENTRE STATION APPROVAL OF FINISHES AND ARTWORK Page 3 Energy efficient HVAC system; Reduced storm water runoff into the municipal drainage system by utilizing green roof landscaping and soft landscaping areas adjacent to other building runoff areas; Bicycle parking; and Landscape with native and drought tolerant species provided. The footprint of the entrance building has been significantly reduced from the 30% design. PUBLIC REVIEW: The VCC Station functional design concept has been reviewed as follows: Commission meeting on December 16, 2009 Advisory Committee on Accessible Transportation (ACAT) Design Subcommittee on November 23, 2009; Public open house on March 10, 2010; and ACAT Design Subcommittee on July 28, 2010. The March 10, 2010 public open house was held specifically to exhibit functional design. There were 51 attendees with 12 written comment forms submitted. In general, the comments received were supportive of the station s functional design. Four raised the need for a PPUDO, one raised the need for proper bike storage, and two suggested the promotion of local employment during construction. General positive comments for the station design were heard in discussions while four written comments complimented the station design. The conceptual design was reviewed with the ACAT Design Subcommittee on November 23, 2009. Staff subsequently reviewed the completed design, finishes, and artwork with Design Subcommittee on July 28, 2010. Comments included: Design post-and-ring bicycle parking at the main entrance to provide a separation from pedestrian routes so that parked bicycles are not a hazard to blind patrons; Consider extending the unpaid elevator shaft from the surface down to platform level for use only when the paid elevator from concourse to platform is not functioning; and Require all future developer connections to concourse level be fully accessible to TTC standards. The second item is currently being reviewed by staff. The other two items will be implemented. The station design, finishes, and artwork will be reviewed at a second public open house in October 2010.
TORONTO-YORK SPADINA SUBWAY EXTENSION PROJECT VAUGHAN CORPORATE CENTRE STATION APPROVAL OF FINISHES AND ARTWORK Page 4 STATION DESIGN AND FINISHES: Exterior: Exhibit 6 Exterior View Exhibit 7 Sections An on-street PPUDO is located next to the main entrance on the west side of Millway Avenue just north of the intersection with Highway 7. A station emergency exit building (SEEB) and vent shafts will come to the surface on the west side of Millway Avenue, between Apple Mill Road and the future Vaughan Street. A second SEEB and vent shafts are located on the south-west corner of the intersection of Highway 7 and Millway Avenue. The electrical substation is located further south and has been designed to allow it to become a part of future developments. The most distinctive feature of this station is the domed main entrance building with a zinc standing seam roof. The metal roof will be constructed as a cool roof with a high solar reflectance to reduce heat absorption, and contain skylights to allow daylight to penetrate down to concourse. Although this station is located outside Toronto, the design team has worked with the City of Vaughan to reach an agreement on how to apply environmental standards, such as the Toronto Green Standard, to subway stations. As this station is largely underground and covered with vegetation, plazas, and sidewalks, only roof areas over the above grade structures are included in calculations. A green roof will be installed on the electrical substation. The dome is supported on a ring-beam clad in prefinished dark grey steel and the building is glazed in bird-friendly fritted glass in curtain wall framing. Bicycle parking will be in the form of post and rings arrayed around both ends of the entrance, located under roof overhangs. Street Level: Exhibit 8 Plan at Grade Exhibit 9 Interior View Surface Passengers arriving by YRT buses will enter the station either through the main entrance or through an underground connection, depending on the future YRT bus terminal concept. Passengers arriving at the station on foot or dropped off at the on-street PPUDO will enter the main entrance through one of four sets of doors. The entrance is open to the concourse level below with an elevator, escalators, and two sets of stairs. Daylight reaches down to concourse level through triangular openings between the doors. The ring-beam remains visible on the interior and is clad in prefinished dark grey steel to match the exterior. The building is glazed in bird-friendly fritted glass in curtain wall framing. Floors are in pale grey terrazzo. Stairs are dark granite with nosings in a paler colour to provide the contrast required to meet TTC barrier-free design standards with a field of TTC detectable warning tile at the top landing. The guardrails around both the triangular openings and the vertical circulation openings are tempered-laminated glass

The ceiling dome is formed from perforated metal panels containing acoustic absorbing material, and along with the skylights, form the art concept. Concourse: Exhibit 10 Concourse Plan Exhibit 11 Interior View - Concourse This station has been designed to maximise potential Transit Oriented Development (TOD) with seven knockout panels; three south of Highway 7, two north of Highway 7, and two just south of the future Vaughan Street. A single continuous concourse level provides opportunities for three future developer connections to the west of the station, and three to the east. An additional knockout panel is provided at the south end of the concourse for a future secondary entrance. All connections enter into the unpaid circulation area. All future connections to concourse level will be barrier-free. A second entrance to the station is provided from the Highway 7 Viva bus facility in the centre of Highway 7 to the south end of the concourse level. The configuration of this connection and the vertical circulation elements is being developed in consultation with Viva, and will be barrier-free. The concourse level also contains TTC service spaces. The collector s booth and associated fareline are located at the centre of the concourse. Moving through the fareline leads to an elevator, escalators, and stairs to platform level. Walls are clad with large ceramic wall panels in a pale grey colour. Floors are in pale grey terrazzo. Stairs are dark granite with nosings in a paler colour to provide the contrast required to meet TTC barrier-free design standards with a field of TTC detectable warning tile at the top landing. The guardrails around the vertical circulation openings are tempered-laminated glass panels with stainless steel handrails. Escalators are TTC standard high deck with stainless steel clad balustrades. The walls of the stair opening are clad in architectural concrete panels. Ceilings are architectural concrete beams with black spray-applied acoustic material in the coffers between the beams. Platform: Exhibit 12 Platform Plan Exhibit 13 Interior View - Platform The subway platform level is served by one elevator, escalators, and two sets of stairs from the concourse level. Emergency exit stairs will be provided from the north and south ends of the platform. Walls to service spaces on the centre platform are clad with large ceramic wall panels in a pale grey colour. Trainway walls will be exposed concrete. Floors are in pale grey terrazzo with yellow platform edge tiles to distinguish both edges of the platform, and a TTC standard wayfinding route is located off center along the length of the platform. Stairs are dark granite with nosings in a paler colour to provide the contrast required to meet TTC barrier-free design standards. Escalators are TTC standard high deck with stainless steel
TORONTO-YORK SPADINA SUBWAY EXTENSION PROJECT VAUGHAN CORPORATE CENTRE STATION APPROVAL OF FINISHES AND ARTWORK Page 6 clad balustrades. The walls of the stair opening are clad in architectural concrete panels. Ceilings are perforated metal panels containing acoustic absorbing material. Options are currently under review for mounting the platform edge sign bands. The optimal location for the platform edge sign band is to have it integrated into the header of the future platform edge doors. In the interim, options are being explored including suspending the platform edge sign band from ceiling or smoke canopies above the platform edges or mounting the information contained on the signs on the train wall. Artwork: Exhibit 14 Artwork A public art selection process resulted in the selection of Paul Raff as the public artist for VCC Station. The artist is intrigued by the dynamics of people interfacing with the built environment. He has developed a piece called Atmospheric Lense which has been approved by the Vaughan Corporate Centre Art Design Review Committee (ADRC). Artwork is integrated into the domed ceiling of the entrance building in a collaborative effort by the artist and the architect. The surface of the domed ceiling will be primarily a diffusion with some panels having a more reflective surface to provide a visual depth, optical richness, and subtle shifts of reflection with movement. Within the dome is a collection of apertures with sloping sides culminating in a skylight providing views to the sky. The skylights are oriented to the solar plane, which is emphasized with a surrounding field of reflective panels. The sides of these apertures will be coloured and angled to match the summer and winter solstices, and the spring and fall equinox. A fourth element is a glowing disk mounted on top of the elevator shaft so it is not directly visible to patrons, but will be reflected occasionally in the surfaces of the dome to provide a point of reference. A brief description of the art concept in the artists words will be placed on a number of plaques throughout the station. Project Impacts: As this site and surrounding area are largely undeveloped, there is minimal potential for impact on the surrounding community during the construction period. VCC Station will be the site of the tunnel boring machine (TB) extraction shaft for construction of the twin tunnels north from Highway 407 Station. To mitigate these environmental impacts, the following items will be in place for construction: Soil and groundwater management to address high volumes of dewatering from the large cut and cover area; Environmental Management Plan to monitor areas potentially affected by dewatering; Construction Monitoring Plans and programs to address noise, vibration, dust control, stray current and tree protection; and
TORONTO-YORK SPADINA SUBWAY EXTENSION PROJECT VAUGHAN CORPORATE CENTRE STATION APPROVAL OF FINISHES AND ARTWORK Page 7 Traffic Management Plan to address Highway 7 detours and truck movements associated with spoils removals. Cost and Schedule: The estimated final cost of construction costs for VCC Station is $200 million, inclusive of HST, including the cross-over tail track. While this current cost estimate will require further use of contingency funds, value engineering and cost reduction measures will be taken on this station work to keep the total Project costs within the approved budget. The proposed project schedule reflects completion of design development to 100% in spring 2011. VCC Station is scheduled for substantial completion by the end of 2014. Next Steps: A second public open house will be held in late October 2010. In the event that any issues arise, a report will be brought to a future Commission meeting. A report for contract award approval will be presented to the Commission in spring 2011. JUSTIFICATION Approval is required to allow the station design to be finalized for tender.
