Procurement Questions Question 1 Question: When you re awarding the project, it s been the practice in the past to take all the additional units that come after the base bid and add them to the base bid to determine the total. In this project that will increase the base bid beyond the $500,000 mark for the wage scale. And the wage scale is crazy. A pipelayer and laborer will be making more than an excavator operator?
