EGLINTON LRT Design Excellence Principles + Requirements Beth Kapusta Senior Manager, Design Excellence October 1, 2015
Metrolinx Design Excellence
• Board initiated mandate to integrate design excellence into all Metrolinx capital investments
• Focus on areas of architecture, landscape architecture, industrial design and urban design
• Key Strategies: • Strengthen corporate design
guidelines and standards • Effective design briefs identifying
expectations, processes and scope • Corporate design review process
and accountability • Design evaluation of capital projects
through procurement • Increasing value of design expertise
in evaluation criteria
GO Transit Train Shed Roof at Union Station - Winner of a 2012 Canadian Architect Award of Excellence
Design Excellence on Eglinton LRT
• P3/DBFM procurement model requires clearly defined specifications and evaluation criteria in advance of process
• Worked with stakeholders to include design as key element of project specific output specifications (PSOS), and bid evaluation
• Set minimum pass/fail threshold for design quality in bid evaluation • Eglinton LRT Design Excellence Principles and Requirements
document established concrete design criteria on which to assess bid compliance, evaluation, and ultimately project execution
• Document forms part of PSOS balancing aspirational vision with binding criteria, and coordinated with technical components of the specifications
• Within compulsory PSOS compliance framework, compliance assessed through a checklist distilled from the document by translating principles into measurable technical specifications
• Eglinton Design Review Panel assembled to review design compliance relative to PSOS for the life of the project
Design Excellence Principles + Requirements
• Built on previously completed and approved Crosstown Design Framework
• Collaboration with City essential to deliver on design excellence mandate, due to impact on public realm, and scope/scale of project
• March 2013 design workshop included private sector design professionals, senior City, TTC, and Metrolinx staff
• Workshop established key design criteria resulting in clear vision and strategy with realistic aspirations
• Clarified need for a system-wide design approach • Identified precedent projects in the international
peer group of Eglinton LRT, which illustrated a successful systems approach
• Compliant demonstration designs developed by gh3 as proof of concept for the underlying principles, and articulation of minimum level of design resolution expected of proponents
Principles of Design Excellence:
A strong conceptual design narrative across the system 1
2
3
4
5
Design that elevates the quality of the passenger experience
Civic character, exhibited through scale, materiality and quality
Clarity and simplicity of architectural expression through integrated design of all systems and elements
Responsiveness to contextual, local and future conditions
A strong + coherent
architectural vision for the
entire line
A strong conceptual design narrative across the system 1
A clear strategy for consistent
and variable elements
Systematic use of colour/pattern
as station identifier + for
passenger experience
Demonstration Designs
Maximized flow
2 Design that elevates the quality of the passenger experience
Openness through optimal spatial penetration
Maximized transparency + daylight penetration
Demonstration Designs
Consistent, well-proportioned open space materials that harmonize
with Station buildings
3 Civic character, exhibited through scale, materiality and quality
Unified surface consistent between interior + exterior, Stations, Stops + Plazas
Scale, massing and exterior treatment informed
by civic considerations
Demonstration Designs
Integrated structural,
mechanical + electrical systems
A clear hierarchy +
plan for user-centred integrated
information
Clearly organized + integrated
hierarchy of signage, amenities
+ activities
Integrated art
4 Clarity and simplicity of architectural expression through integrated design of all systems and elements
Demonstration Designs
Integration with historical context
5 Responsiveness to contextual, local and future conditions
Massing that responds to existing + planned horizontal datum lines and setbacks
Public realm of Stations + Stops seamlessly connected to the public right of way
Demonstration Designs
A strong conceptual narrative vision across the system
