How do I plan and build a large city from a green field ?
I need so much information !!!!
Everything is connected to everything !!!!
A Green City from a Green Field
Thinking of a City as a Dynamic System

“The Construction Sector is known for low productivity, poor integration, and a terrible record of “fit and interference” no other sector would tolerate. There is little or no life cycle management!”
“When do we begin thinking of cities as integrated systems – dynamic systems – the way we think about aircraft or spacecraft?”.
How do we escape this?

“How can I better integrate the city’s systems for the movement and management of goods, people, water, air, electricity ?”
Thinking of a City as a Dynamic System
Cities face serious challenges ? Water? Heat Islands ? Access to food? Air Quality ? Crowding? Not making the climate worse?
What tools are there to help us cope?
There are so many solutions!
• Green roofs – walls• Solar roofs - walls• Suitable materials• Building form – size/orientation• Passive ventilation• Better use of green spaces• Increase ground permeability• Reduce use of air conditioning/heating• Increase/decrease density

Lots of Strategies!
How do I choose?

Intelligent City Models can help!
• What is a city model?
• City Models are a foundation for planning, construction and operations.
• A concrete example – Permit Infringement.
• Other real world problems.

What is an Intelligent City Model ?
What is an Intelligent City Model?
• Comprehensive, multi-level of detail – 3D – model of all city structures – suitable for simulation & analysis and decision support.
• Support Multiple Applications in – Planning– Construction– Operations– Communications
• Fundamental information resource

Application to Permit Infringement!
City Model – Application to Permit Infringement
City developers submit drawings for a project, but then build something that deviates from the submitted drawings.
12 April 13, 2023Powering the Geo-Web
A technique is to be provided by which deviations between the actual built structure and the drawings submitted in the permit process can be detected.

How do I plan and build a large city from a green field ?
City Model Application - Green City from a Green Field
1. Develop a design process
2. Integrate the design process into the fabric of the city.
3. Integrate permit/zoning/design together from the start.
4. Build/Integrate intelligent city model from the start.
City Model – Application to long term planning

Application to Security Planning & Surveillance
Security Requirements
• Security applications require access to the entire city model(s) + additional detail.
• Additional detail is confidential.• Security applications require simulation
functionality (e.g.):– Inter-visibility.– Electromagnetic field mapping.– Radar field mapping– Internal/external routing analysis

How to build an intelligent city model!
How to build the City Model? - Principles
• Start before the City if you can.
• Focus on Intelligent City Models – not “eye candy”
• Build the business processes to build the model into the fabric of the city.
• Automate model construction as much as possible.

Drive innovation ! Drive new applications & solutions
Summary
• Urban challenges are urgent!
• Urban challenges are complex & interconnected!
• Intelligent city models can help!!
• Models must be sustainable – current – accurate!
• Models must be shareable – usable by diverse stakeholders
• Open standards (e.g. GML, CityGML, ifc, …) and information infrastructure technology can realize model potential !!
