Give a brief description of Building Information Modeling.
What will be an ideal response?
Building Information Modeling (BIM) is set to revolutionize the way buildings are designed, constructed, and maintained. Architects and engineers use BIM to generate a three-dimensional model of a building with embedded links to other project information. In its current state BIM has a range of capabilities including: drawing, construction estimating and scheduling, interdisciplinary coordination, and generating fabrication protocols.

Stainless steels can be susceptible to stress corrosion cracking under certain conditions. A materials engineer is interested in determining the proportion of steel alloy failures that are due to stress corrosion cracking.
a. In the absence of preliminary data, how large a sample must be taken so as to be sure that a 98% confidence interval will specify the proportion to within ±0.05? b. In a sample of 200 failures, 30 of them were caused by stress corrosion cracking. Find a 98% confidence interval for the proportion of failures caused by stress corrosion cracking. c. Based on the data in part (b), estimate the sample size needed so that the 98% confidence interval will specify the proportion to within ±0.05.
