You have a business to run.

Let us manage your construction and move project.

We can save you time, money and stress by managing your commercial relocation or renovation.  From finding the right design and engineering teams to making qualified contractors compete for your business. We are experts at managing details that often don’t get properly addressed. This ensures you move in on-time and on-budget to a space that meets all your needs.


You know all those horror stories you hear about construction projects going wrong and being over budget and late?


Our only business is managing the entire project to make sure those stories are never your stories!


Critical Path Projects is uniquely positioned to help businesses who are moving from one space to another or renovating their existing space. We understand and manage the whole process from signing a lease, managing the design and engineering teams, finding a qualified contractor and managing the construction right through to helping you relocate on move-in day.


Critical Path Projects represents your interests, period. Project Management for commercial construction projects is our only business. We are experts at what we do and will deliver your project for the lowest cost on schedule.



A big part of what we do is save you money. We know where to look for opportunities to efficiently save on your budget without compromising the design or quality of construction. In fact, on most projects, we will save you more than our fees!

We do this by:

  • Ensuring the design and engineering team has a clear budget to work to.   The parts of the project you don’t see; the mechanical and electrical work can be 50% of the project budget. We know how to instruct the mechanical and electrical engineers to design as efficiently as possible so you have more money to put toward the finishes you do see. 

  • Ensuring all work is competitively tendered to contractors and subtrades who want your work and want to compete for your work. Not all contractors want to compete and some are too busy to price competitively. We’ll find ones that want work and will bid competitively.   

  • Using our expertise to negotiate savings on big ticket items you would otherwise pay full price for. 


Critical Path Projects provides a wide variety of project management, design and construction related services. Whether you engage us as full service project managers or simply choose one or more of the services listed below, you can be confident that Critical Path Projects will always look after your interests first.
