A crew is made up of the labor and equipment resources necessary to construct an item. For example, a framing crew might consist of two labor resources, a Carpenter 1 and a Carpenter 2. You might assign the framing crew to your 2x6 stud items.
If you assign a crew to an item, Sage Estimating (SQL) includes the cost of that crew when calculating the item price. The hourly rates and other costs used to calculate the total cost of the crew resources are stored in rate tables.
