Colin Tomlinson 

Founder & Managing Director

Colin Tomlinson is a leadership and project management specialist with a career spanning military service, construction and high-performance training. As the founder of 150CLD, he helps leaders in construction and engineering develop the skills they need to navigate complex projects, drive efficiency and build cohesive teams.

Colin’s approach is rooted in real-world experience. After a distinguished career in the British Army, he transitioned into the construction sector, where he quickly saw the industry’s biggest challenge—technical skills alone weren’t enough. The real difference between a smooth-running project and a chaotic one? Leadership, communication and the ability to get people working together effectively.

Since founding 150CLD, Colin has worked with major infrastructure firms, engineering leaders and ex-military professionals moving into construction careers. His leadership programmes focus on reducing rework, improving decision-making and creating high-performing teams—helping professionals not just lead, but lead well.

Colin is also the host of the Site Story podcast, where he dives into the human side of construction and engineering, exploring how different roles interact, the challenges they face and what makes a great leader in the industry.

When he’s not training the next generation of construction leaders, you’ll find Colin sailing, mentoring veterans or reminding project managers that firefighting shouldn’t be a daily job requirement.
