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.
The average construction cost is much higher than the 2011 cost, which was $184,125, and NAHB notes it is the highest itâs been since 1998.
