Mega projects are notorious for missing deadlines and budgets, but the M4 Sydhavn Metro extension in Copenhagen broke the pattern. Learn how trust-based collaboration, strong governance and a shared vision helped create a rare success story that delivered on time, on budget and with lasting value.

Understanding the challenge of mega projects
Mega projects are large-scale endeavours that combine complex stakeholder landscapes, long time horizons and high uncertainty. Drawing on experience from major transport and infrastructure projects, Implement Consulting Group explores how managing risk, complexity and benefits alignment can make or break delivery success.

Trust and collaboration as success factors
Mikkel K. Jensen, project director at Metro Selskabet, shares how the M4 Sydhavn line overcame major challenges, including the COVID-19 pandemic. The team’s trust-based cooperation with contractors, suppliers and authorities enabled flexible problem-solving, helping the project stay on time and within budget while exceeding passenger expectations.

Governance, learning and leadership
Clear mandates, competent teams and an adaptive governance framework were crucial. Both Implement Consulting Group and Metro Selskabet emphasise that experienced people, open communication and shared purpose drive success. Continuous learning, reflection and empowering decision-making at every level sustain performance across future mega projects.
