What is an annotated bibliography? An annotated bibliography provides a brief account of the available research on a given topic. It is a list of research sources that includes concise descriptions and evaluations of each source. The annotation usually contains a brief summary of content and a short analysis or evaluation.
An average commercial steel building costs between $16 and $20 per square foot, including building package (I-Beams, purlins, girts etc.) , delivery, foundation and the cost of construction.
Buildings by experienced contractors cost about .5-4% more than wood frame structures of the same design. Typical new U.S. buildings cost $60-100 per square foot. Building walls of ICFs adds $1.00-$4.00 to this figure.
