A guide to estimating with building information modeling and traditional modeling using Autodesk Quantity Takeoff

This Master's thesis seeks to develop an understanding of Building Information Modeling in the construction management industry specifically in estimating through the use of Autodesk Quantity Takeoff. The goal is to provide students with a guide into how to accurately and efficiently perform a quantity takeoff and turning that takeoff into an estimate. An overview to what estimators do and the types of projects they work on was analyzed. A comparison between how estimators manually perform quantity takeoffs and using Building Information Modeling to perform quantity takeoffs was performed. A sample from Revit Architecture and Structure was used as the model for the quantity takeoff. An overview of using the building information modeling model to perform a full quantity takeoff was first performed. A subsequent quantity takeoff was then performed using manual takeoff techniques. The structural and architectural trades were taken off with suggestions for a more efficient quantity survey. Pricing of the quantity survey was then performed using RS Means through material and labor unit costs. The estimate was then compiled and a report was created. Conclusions were then formed on the usefulness of the program and building information modeling in not only the estimating portion of construction management, but the industry in general.
