Goal: Implement compact, sustainable cities in Asia that are ecological, livable, and smart
Positioning: To serve as a key proponent for the development of compact, low carbon cities in Asia using a holistic and integrated urban management approach
Principle: Employ a multi-disciplinary, multi-sectoral approach to every stage of a city’s
development cycle
Tool: Sustainable System Integration Model (SSIM)
• Fully leverage AECOM’s professional experience in planning, design, economy, energy, transportation, ecology, environment,
water management, green construction and other fields
• Committed to the concept of sustainable development
• Participate in the entire life cycle of urban and land development, from planning to implementation, monitoring, management
and continuous optimization

What is the Sustainable Systems Integration MethodTM (SSIMTM)?
• SSIMTM is a decision support
method/tool for clients
• SSIMTM is an integrated, whole
systems approach to planning,
design and engineering
• Systems are optimized from a
cost/benefit perspective to
target the “biggest bang for your
buck”
• SSIMTM has been extensively
used on private sector, public
sector and federal applications
