resilient rɪˈzɪlɪənt/ adjective able to withstand or recover quickly from difficult conditions

What do we mean by resilient infrastructure?
7
resilient infrastructure
rɪˈzɪlɪənt/ ɪnfrəstrʌktʃə/
noun
physical and organisational structures able to adapt towards the physical, social and
economic changes within a city
=
Healthy & Resilient Cities
Promote active travel on foot and bicycle
Use public transport to extend the range of active travel
Have good air quality, natural lighting and no urban heat islands
Have a diverse mix of land uses at local scale
Shape the built environment to promote opportunities for active and healthy living!

UN Development Goals W+B Sustainable Design Principles
10
The Dutch Approach - Integration
11
- Integrated vision: vision led, collaboration, engagement
- Integrated design: multi disciplinary, process loops, adaptive
- Integrated systems: multi functional, circular economy
Integrated vision: Engage, design, then engage again
12
Engagement, not just consultation
Multi faceted:
-traditional: face to face, workshops, site visits
-Innovative: virtual reality, online platforms , social media, design thinking
Multi level:
-stakeholders, practitioners, public, children
-quick, temporary engagements vs permanent
Virtual Reality – a communication tool
13
91% of the public surveyed cannot read plans* so we enable them to experience their
street, their city, their designs in a virtual way and collect their feedback and use in our
designs
Www.beleefdevestdijk.nl
* W+B Engagement statistics Eindhoven, Netherlands (2016) 1000+ responses
Integrated design: collaborative, innovative design
14
Multi disciplinary
- engineers sit alongside urban designers, landscape architects and planners
Process loops
- engagement feedback fuels design process
Adaptive
-always designed with resilience and sustainability at the forefront
-Are we being innovative to future protect?
Integrated systems: multi functional design
15
We are specialists – are we thinking of all specialties at all times?
Water Management – (SUDs, flood management, erosion etc)
Active Travel
Civil engineering
etc
Are we using the best way to design, to communicate, to build?
International iconic projects

˗ Jakarta Masterplan, Indonesia: masterplanning, engineering, coastal defense
˗ Beira Masterplan, Mozambique: masterplanning, engineering, water management
˗ Promenades des Fleurs, Luxembourg: sustainability, landscape architecture
˗ Building with Nature, Netherlands: urban water management, drainage
˗ Utrecht Central Station Development Plan: masterplanning, mobility, engineering
˗ Transit Oriented Development, Netherlands: urban planning, masterplanning, EIA

˗ flood protection and urban development
˗ land subsidence due to groundwater extraction
˗ densely populated metropolis
˗ increasing urbanisation
˗ Great Garuda
˗ land reclamation increases financial feasibility
Room for the River, Deventer

Room for the River, Deventer

˗ in Witteveen+Bos head office’s ‘front yard’
˗ expansion and excavation of floodplains, high water channels, nature development,
recreation, water sport
˗ more room for the IJssel river over a distance of 10 kilometres
˗ lowering of water levels by 8 - 18 centimetres at two locations
˗ Witteveen+Bos contributed to 14 of the 39 Room for the River projects in the
Netherlands
Cycle infrastructure design: Multi functional & resilient
So how do we do it successfully?
22
We let the Landscape Architects project lead!
Cycle infrastructure planning: Strategic
23
Its usually not actually about cycle infrastructure design……
Cycle infrastructure planning: Strategic
24
Look at the needs of the users – are they really that different?
- Safe, quick, visible
Cycle infrastructure planning: Strategic
25
Look at the overall network
Cycle infrastructure planning: Strategic
26
Look at the added value
Cycle infrastructure design – Detail

Education & design guidance
‘Quick wins’
Temporary interventions e.g. play streets, temporary road closures
Small infrastructure additions e.g. cycle furniture at junctions
System interventions e.g. Green wave
Infrastructure interventions e.g. filtered permeability, Turbo roundabouts,
segregation, reallocation of space,
NTU Campus, Singapore
Vision: To be an eco friendly campus and increase cycling rate
W+B conducted a study to identify ‘Quick Wins’ to achieve the desired vision. The
resulting recommendations were:
• Increase safety at roundabouts for cyclists.
• Increase attractiveness and comfort of current infrastructure.
Cycle-friendly redesign of Oslo City centre, Oslo Norway
10 yr programme with a vision for carbon neutral
urban areas and high-quality architecture.
‘Cycle for All’ concept (with OKRA Landscape
Architects & Grindaker Landscape Architects.)
System Interventions: easy-to-implement
measures
•reorganising traffic flows to create space for
cyclists (rather than ‘adding’ cycle lanes to the
already busy streets of Oslo).
•closing a part of the street for car traffic
•multi-modal traffic plan
Design of Fast cycle route (18 km)
30
Fast cycle route between the two Dutch cities
Apeldoorn and Deventer to encourage
commuters between these two cities to shift from
car to bicycle use.
Infrastructure Interventions:
•design speed of 25 km/hr, wide radiuses and
maximum slopes of 1:50 to ensure a smooth and
comfortable ride.
Niewendijk, Netherlands – using urban flooding to create a green identity
31
Niuwendijk appointed W+B to provide flooding
solutions
We looked at the ‘Added Value’:
•Instead of just engineering flood tanks and
overflow, we mitigated flooding
at surface level and turned the
solution into green identity of town
•Created multi purpose ‘green areas’
– aesthetic, bio diverse , flood tanks
and car parking
Inverness – Sustrans Community Links PLUS Funding Bid
32
Appointed in 2016
Brief: to design ‘Dutch cycle infrastructure’ for parts of an Active Travel Network
Approach: (Engineer led!) Designs received well, focus on technical detail, overall
‘added value’ story lost
Appointed in 2017
Brief: to develop the designs
Approach: (Landscape Architect led) Focus on the narrative and overall added value
