Focus on “big ticket” items when seeking materials to meet regional purchasing requirements. If you can find regional materials like structural steel and concrete, these more expensive materials will go a long way toward meeting the required percentage of your materials budget. This approach allows you to Iimit the overall number of items you need to track and document, reducing contractor headaches. If these big-ticket items do not get you to the threshold you’re trying to meet, target medium-priced items next until you reach your goal.
