Estimating Review


Above is a screenshot of my Assembly Cost Estimate for the Estimating Assignment. I found the assembly estimate to be easier than the unit estimate because it was more general. The unit estimate required more thought and was more indepth. The estimating process is long and complicated. There were numerous times when I thought I had successfully finished my estimate, only to find out I had overlooked a detail of the building process. My first attempt of the unit estimate did not include the actual concrete. All I had was the cost for the footing placing, including vibrating. I had overlooked the part of the description that said "excludes material." After I had all the concrete material, I realized that I was missing the formwork, vapor barriers, and jointing. So finally after numerous attempts, I was left with what I think is a complete unit estimate.
