Staff at Evan Terry Associates and a Birmingham general contractor developed the original estimates for the Standard Barrier Survey. They have been verified and updated through eight years of surveying in a variety of facilities nationwide. They are adjusted for each project according to the factors below and appear in the possible solution pages for that project as adjusted.

Basic Costs

$0.00     Cost Estimate is expected to be zero.

$1.00     Unit Cost Estimate is too dependent on existing conditions to set a generic estimate. Surveyor must estimate in the field! This will show up as “OVERRIDE” in the Possible Solutions Modified Unit Cost column.

$#.##     "Core" or basic unit cost estimate based on publicly bid work in 1993.
