Corrigan Model – Text

Corrigan Model


Every successful endeavor requires the leadership and support of the ownership and top management. Collaboration reliability and trust are built by these guiding Corrigan principles:

  • An engaged and enlightened owner is the key component
  • You can’t make a contract with a man who isn’t in the room
  • Adversarial relationships are not productive
  • You can only expect what you pre-plan and inspect
  • Everyone adds value if empowered to do so
  • Open communications builds teamwork and creates better solutions
  • Reliable partners build mutual respect
  • Thinking things through upfront is far cheaper than re-doing work

Drawing & Specification Review

As plans and specifications are developed, so is the COST ESTIMATE. Estimating is a careful and thoughtful process that is designed to identify any gaps in the design process and to test the integrity and reliability of the budget.
