My estimating for the price and quantity of concrete involved four different excel files. The concrete included in the estimate was the slab, the continuous footings, and the column footings. I used the website RS Means to find the costs for each item involved in the construction process for concrete. This included materials such as reinforcing steel, dowel rods, vapor barriers, and gravel. Using square feet, linear feet, or cubic feet, I was able to calculate the appropriate number of materials I would need for this project. The first step was to calculate the cost of a single quantity of material and the resulting cost, which is identified in "Unit Cost" and "Total Unit Cost". After that, I simply multiplied the price of one unit by the number of that material actually needed. This is represented by "Total Assembly Cost" and "Total Unit Cost". The interesting part of these take-offs was that the Assembly Cost was significantly more expensive than the Unit Cost.
