Method Comparison

We are an industry leader in Lean project planning and construction with committed company leadership and a highly trained team of certified Lean specialists. Lean project delivery is not a widespread practice in the construction industry, which is typically known for waste, budget overruns and schedule delays. The reduction of waste and continuous improvement driven by the application of Lean principles, translates to significant time and cost savings which ultimately result in maximized value delivered to our clients.

* What Causes Scope Change & Costs Creeps?

Cost creep is unlikely on IDB projects due to the inherent alignment between all parties involved in the project. For DBB and EPC projects, designer and builder efforts are commonly misaligned, which makes scope change and cost creeps much more likely. Finally, on EPCM projects penalties are the most common mechanism to conrol these issues but they are rarely enforced. (Less than XX% of projects have penalties enforced.)

Front-End Engineering and Design (FEED)

Similar to a FS (Feasibility Study), a FEED is a way of developing the scope and do preliminary design work to get a concept or budgetary cost for project justification. The fundemental difference is that a FEED allows the client to determine the level of budget accuracy they want to achieve 70% to 95% accuracy.

Contractor Role & Responsibility Responsible for all aspects of the project including engineering, procurement and construction. Self-performs the majority of actual site construction. Responsible for construction execution and undertakes actual site construction. Responsible for all aspects of the project including engineering, procurement and construction. Does not necessarily self-perform engineering or construction. Responsible for engineering, procurement and construction management. Does not perform any actual site construction.

One Point of Contact Yes No Yes No
Contract Flexibility Most flexible Flexible More flexible Less flexible
Contracted Parties Owner and IDB Contractor Owner, Engineering Consultant, General Contractor Owner, Engineering/Construction Contractor Owner, Engineering/Construction Contractor
* Why You Want Fewer Cooks In The Kitchen

Having a single point of contact saves you time and reduces the odds of inconsistent communication between third parties. IDB offers a single point of contact for the owner and the most collaborative environement for all other parties involved.

Fewer Choices = Less Risk

As an owner, you’ll always have choices to make about your project. The more choices – particulalrly ones outside your area of expertise – the higher the risk. By choosing the IDB methodology, you get to reduce the number of choices and outsource the associated risk to your IDB firm.
