DIR Case Study Wiki

A reference resource for studying how critical infrastructure systems around the world are designed, built, and governed to achieve resilience.

Overview

The DIR (Designing Infrastructure for Resilience) Case Study Wiki catalogues real-world case studies across sectors — water, energy, transport, digital, and more — and evaluates them against a consistent set of resilience principles. The goal is to make infrastructure resilience knowledge accessible and comparable for researchers, policymakers, engineers, and students.

Features

• Structured Case Studies: Each case study follows a consistent format covering overview, timeline, stakeholders, digitalization, hazards, costs, and resilience assessment
• Resilience Framework: All cases are evaluated against six Principles of Resilient Infrastructure
• Comparative Analysis: Standardized structure enables cross-sector and cross-geography comparison
• Educational Resource: Supports learning from diverse international approaches to infrastructure resilience

Case Study Structure

Each case study includes:

• Overview — Summary of the infrastructure, its scale, and strategic purpose
• Timeline & Location — Key dates, phases, and geographical context
• Stakeholders — Ownership, governance, and parties involved
• Digitalisation & Data — Digital tools, sensors, and data systems
• Hazards — Exogenous and endogenous risks
• Cost & Benefit — Financial scale and value delivered
• Resilience Principles Assessment — Evaluation against the six principles
• Futures — Planned developments and emerging considerations

Six Principles of Resilient Infrastructure

1. Accountability — Clear ownership and long-term governance
2. Protected by Design — Robustness, redundancy, and fail-safe engineering
3. Environmentally Integrated — Working with natural systems and resource efficiency
4. Socially Engaged — Community involvement and equitable outcomes
5. Adaptive Management — Capacity to evolve with changing conditions
6. Continual Learning — Systematic capture and application of lessons

Getting Started

Simply open index.html in a web browser to explore the wiki. No build process or dependencies required.

Current Case Studies

• Singapore Deep Tunnel Sewerage System (DTSS) — Large-scale underground wastewater management infrastructure

More case studies are planned and under development.

Design

The wiki uses a clean, accessible design with:

• Custom CSS styling (no frameworks)
• Responsive layout for mobile and desktop
• Typography using Source Serif 4, DM Sans, and JetBrains Mono fonts
• Consistent color scheme with academic/professional aesthetic

Contributing

Case studies marked as "Planned" are under development. Sections marked with TO DO badges indicate areas needing further research.

If you're interested in:

• Contributing a case study
• Providing additional data for existing entries
• Suggesting improvements to the framework
