As you know, square-foot costs can vary widely, making it difficult to use them for estimating and budgeting. But the 2011 ENR Square-Foot Costbook practically eliminates this problem by giving you costs that are based on actual projects -- not hypothetical models. For each building type you get a detailed narrative with background information on the specific project. This lets you put the cost data into context and make appropriate adjustments to your own projections. Developed in partnership with Engineering News Record, Design Cost Data, and BNi Building News, this ready-reference costbook also features illustrations of each building type, a guide to 5-year cost trends for key building materials, Plus detailed unit-in-place costs for thousands of items -- from asphalt and anchor bolts, to vents and wall louvres. By purchasing this book, you will also receive the 2012 edition, on a no-risk free trial basis.
