Civil Engineering Project - open to bidding

Case Study: "Time is Money: Financing a Skyscraper”A simple cost model for the construction of a skyscraper could be based upon the following:[login to view URL] land area (acres) and the price of the land ($0.1 to $10 million/acre)[login to view URL] costs of clearing the land ($10 to $50,000/acre)[login to view URL] foundation ($2-4 million/acre)[login to view URL] weight-bearing [login to view URL] exterior of the building, including windows, exterior materials, waterproofing, and [login to view URL] [login to view URL], air-conditioning, [login to view URL] of a dramatic entry area and [login to view URL] [login to view URL] finishingFor any infrastructure development, we are generally considering whether or notto begin a particular type of project. We probably have several basic design and location options plus numerous minor variations on these options, e.g. variations in size or quality of components. From the underlying logic of the project, we can developa function that relates the project costs to the design and location possibilities. Separate functions can be used to estimate the initial investment costs as well as the fixed and variable operating costs. As engineers, it is our job to try to understand what options are available, including new designs or construction techniques as well as "tried & true" approaches.
