Estimating

Unit Cost Estimate










Assembly Cost Estimate












To complete a take off for the concrete included in this project, I created two excel files. One to show a unit cost estimate for the project, and one to show the assembly cost estimate for the project. For this estimate, not only did you have to include the concrete, you also had to include the materials and labor needed to complete the process. The assembly cost estimate included the main portions of concrete such as: the strip and spread footings, the 4” and 6” slabs, and the concrete wall. On the other hand, the unit cost estimate included the pieces and parts used to put the concrete into place. It included things such as: the elevated slab, the structural concrete ready mix, the concrete forms, the needed excavation; high chairs for the reinforcing steel, vapor retarders, and gravel fill. I used RS means to find the costs for all the pieces and parts involved in the construction process. RS means would give you the individual costs of each material, which made it easy to calculate the total cost of the concrete included in the project. All I had to do was take the information RSmeans provided, and multiply the cost of one unit by the number of units I would need for this particular project.
