It helps considerably if these professionals understand a design-build approach that reuses materials, or harnesses reusable ones while efficiently collaborating with providers—structural and mechanical engineers, electricians, and interior designers, among others—involved in every phase of construction. A resourceful construction manager should be able to execute and complete tasks within or around the set deadlines without having to inflate the budget.
