"Urban Flooding has been ‘all the rage’ in newspapers recently. But Mark feels that it would interesting, and perhaps provocative, to discuss these flooding issues in light of the current state of infrastructure as opposed to blaming flooding on “climate change”, which journalists seem to be quick to do."
The Speaker
Mark Andrews is the founder and Chief Consulting Engineer of ME Associates, a Toronto-based consultancy specialising in infrastructure resilience and urban systems. With over three decades of experience in water management, urban planning, and civil infrastructure, Mark has led numerous international projects focused on sustainable urban development and flood mitigation.
​
Mark has been responsible for project delivery to municipal, institutional, and private sector clients across Canada and overseas. In addition to specific expertise in asset planning, performance evaluation, and sewer rehabilitation, Mark has experience in project planning, detailed design, operations engineering, and contract administration.
In parallel with his consulting, Mark has been collecting books on applied science and civil engineering since his university days in the 1970s and, over the years, has become a leading engineering historian. He was introduced to our President, Jean Venables, by Honorary Member, Julia Elton, at an event at Pembroke College, Cambridge in 2022 to launch Mark’s book ‘The Science and Engineering of Water; an illustrated catalogue of books and manuscripts on Italian hydraulics, 1500-1800’. A second volume in the series, related to hydraulics beyond Italy and around the globe, has just recently been released.
Introductory Presentation
As background to the discussion Mark invited us to discuss our responses to climate change and the investment needed in improved and new infrastructure, using the challenging examples in the field of Urban Flooding.
Discussion
Mark posed three questions which each of the five dinner tables considered. The responses presented are summarized below:
Question 1:​ “Which public initiatives should have their funding reduced to prioritize climate change impacts and urban flooding?”
​
Key Insights:
-
Wrong Question Framing: Many participants felt the question was misdirected. Rather than cutting funding from essential services like healthcare or education, the focus should be on better use of existing funds, whole-life costing, and system-wide planning.
-
CapEx vs OpEx: Capital Expenditure is easier to secure than operational expenditure. However, maintenance and resilience require sustained Operational Expenditure, which is often neglected.
-
Innovation and Efficiency: The construction sector must improve productivity, planning, and innovation. Projects should not start without full design and approvals, avoiding costly overruns (e.g., HS2).
-
Alternative Funding Models: Suggestions included land value capture, developer taxation, and incentivizing civic responsibility (e.g., reduced council tax for sustainable land use).
-
Insurance and Risk Sharing: Only 4% of national infrastructure is insured. Exploring insurance models for infrastructure could help manage financial risk.
Question 2: “Who is better suited to promote the need for increased infrastructure funding: journalists or industry experts?”
​
Key Insights:
-
Joint Responsibility: Most agreed that both journalists and engineers have roles to play. Journalists can capture public imagination, while engineers must clearly articulate risks and consequences.
-
Strategic Communication: Engineers need to improve storytelling, develop elevator pitches, and engage in stakeholder management. Training in communication should be embedded in engineering education.
-
Go-To Spokespersons: The industry should identify credible, consistent public voices (e.g., like Simon Calder in travel) to represent engineering issues.
-
Social Media and Influencers: Leveraging social media and influencers can help reach younger audiences and build public support for infrastructure investment.
-
Trade Bodies and Regulators: These institutions must step up to advocate more effectively to government and the public.​
​
Question 3: “How do we encourage the growth of the engineering industry to support long-term infrastructure needs?”
​
Key Insights:
-
Rebranding Engineering: The profession needs a broader, more attractive image. Emphasize the social impact, problem-solving, and interdisciplinary nature of engineering.
-
Education and Outreach: Engage with schools, colleges, and universities to promote engineering careers. Highlight real-world impact and career diversity.
-
Diversity and Inclusion: Tap into underutilized talent pools, such as refugees with STEM backgrounds, to address workforce shortages.
-
Career Pathways and Recognition: Improve career progression, recognition of technical expertise, and financial incentives to retain talent.
-
R&D and Innovation: Invest in research and development to make the sector more dynamic and appealing to younger generations.
-
Unified Profession: Support for the unification of engineering disciplines (e.g., Uff Report) to strengthen identity and influence.
