Founded on a single, powerful idea.
Dedicate a team of project leaders to advocate for a client.
Leaders. Partners. Advocates.
What makes a project leader? Unlike a project manager, a project leader is your partner. We share your vision, supply you with strategic expertise, deploy the right team, and inspire confidence.
A project leader is your advocate. We champion your project. We prioritize your goals. We treat every client like you are our only client.
A project leader is just that—a leader. We seek out value. We anticipate and resolve problems. We assume and mitigate your risks.
Colliers Project Leaders. We’re not just project managers. We go well beyond costs, schedules and project plans.
We’ve led over 18,000+ projects that:
Make cities livable.
Enhance workplaces.
Create spaces worth coming back to.
Improve patient care.
Deliver clean drinking water.
Build a sustainable future.
And so much more.
We act for owners to drive value and performance in capital projects.
We share their vision and protect their interests so that they can be confident of success.
