Costs per square foot were developed for each wall system by identifying all material, labor, equipment and 10% mark up for general conditions
required to represent a complete cost. The items were priced by conducting an intense survey of contractors in each of the regions for the material
and labor costs involved in each wall system.
Work on the project was performed independently by E.J. Brown, Inc., a recognized authority on estimating in the Southeast.
The costs developed are initial construction costs only and do not include maintenance or operating costs associated with the different wall
systems. Although the actual costs may vary with location, time, and contractors, the comparative relationships between wall systems and geographic
regions should remain approximately the same.
