The following table, based on the table published in Building Safety Magazine, shall be used to determine construction
costs per square foot. Adjustments may be determined to be necessary by the building official for unusual projects.
The unit costs are intended to comply with the description of "valuation" in Section 108 of the 2003 International
Building Code and thus include architectural, structural, electrical, plumbing and mechanical work. The unit costs also
include the contractor's profit, which should not be omitted.
If there are differences between the value of the project calculated using this table, and the contract valuation, the
greater number shall be used.
This table shall also be used to calculate plan review fees.

For SI: 1 pound per square foot = 0.0479 kPa, 1 mile per hour = 0.447 m/s.
a. Weathering may require a higher strength concrete or grade of masonry than necessary to satisfy
the structural requirements of this code. The weathering column shall be filled in with the
weathering index (i.e., "negligible," "moderate" or severe") for concrete as determined from the
Weathering Probability Map [Figure R301.2(3)]. The grade of masonry units shall be determined
from ASTM C 34, C 55, C 62, C 73, C 90, C 129, C 145, C 216 or C 652.
b. The frost line depth may require deeper footings than indicated in Figure R403.1(1). The
jurisdiction shall fill in the frost line depth column with the minimum depth of footing below finish
grade.
C. The jurisdiction shall fill in this part of the table to indicate the need for protection depending on
whether there has been a history of local subterranean termite damage.
d. The jurisdiction shall fill in this part of the table with the wind speed from the basic wind speed
map [Figure R301.2(4)]. Wind exposure category shall be determined on a site-specific basis in
accordance with Section R301.2.1.4.
e. The outdoor design dry-bulb temperature shall be selected from the columns of 97Y2 -percent
values for winter from Appendix D of the International Plumbing Code. Deviations from the
Appendix D temperatures shall be permitted to reflect local climates or local weather experience
as determined by the building official.
f. The jurisdiction shall fill in this part of the table with the seismic design category determined from
Section R301.2.2.1.
g. The jurisdiction shall fill in this part of the table with (a) the date of the jurisdiction's entry into the
National Flood Insurance Program (date of adoption of the first code of ordinance for
management of flood hazard areas), (b) the date(s) of the currently effective FIRM and FBFM, or
other flood hazard map adopted by the community, as may be amended.
h. In accordance with Sections R905.2.7.1, R905.4.3.1, R905.5.3.1, R905.6.3.1, R905.7.3.1 and
R905.8.3.1, where there has been a history of local damage from the effect of ice damming, the
jurisdiction shall fill in this part of the table with "YES". Otherwise, the jurisdiction shall fill in this
part of the table with "NO".
i. The jurisdiction shall fill in this part of the table with the 100 -year return period air freezing index
(BF -days) from Figure R403.3(2) or from the 100 -year (99%) value of the National Climatic Data
Center data table "Air Freezing Index — USA Method (Base 32°Fahrenheit)" at
www.ncdc.noaa.gov/fpsf.html.
j. The jurisdiction shall fill in this part of the table with the mean annual temperature from the
National Climatic Data Center data table "Air Freezing Index — USA Method (Base
320 Fahrenheit)" at www.ncdc.noaa.gov/fpsf.htmi.
