I found this in Wikipedia and highly recommend this for review for all estimators, project managers and even people who are in accounting that work with budgets and day to day construction operations. This is actually better than what I find in most construction estimating textbooks. It is important that everyone understands common construction and estimating terms so there is no confusion. A common term that I find companies struggle with is Markup and Margin. They are related but not the same calculation and there are many other terms that should be well defined in your organization.
