Chapter 1Scope and AdministrationChapter 1 has historically been re-written by Kentucky so as to address Kentucky specific needs and interests regarding building construction and code application.

The 2013 KBC follows the same formatting as the 2012 IBC.

Many of the KY amendments to Chapter 1 is code text carried forward from the previous edition and many you have seen since the1980 edition of the KBC. However, there are a few new sections we will review.

The underscored language is not new to the code but is new to the KBC. The 2013 KBC no longer deletes this text. The new language extends the codes intent beyond that of establishing safeguards for the public and building occupants.

It extends application to the protection of our fire fighters and first responders during any emergency operation and event. 2007 KBC2013 KBC

Section 101.3 PurposeIBC text was deleted as an amendment to create this section in the 2007 edition.New text added via IBCSection 101.3 Intent. The purpose of this code is to establish the minimum/maximum requirements and safety to life and property from fire and other hazards attributed to the built environment and to provide safety to fire fighters and emergency responders during emergency operations. 4

Section 506.2.1Width LimitsRevised text and new equation via 2012 IBC added for clarification

506.2.1 Width limits. To apply this section the value of W shall not be less than 20 feet. Where the value of W varies along the perimeter of the building, the calculation performed in accordance with Equation 5-2 shall be based on the weighted average calculated in accordance with Equation 5-3 for portions of the exterior perimeter walls where the value of W is greater than 20 feetW shall be measured perpendicular from the face of the building to the closest interior lot line. Where the building fronts on a public way, the entire width of the public way shall be used. Where two or more buildings are on the same lot, W shall be measured from the exterior face of each building to the opposing exterior face of each adjacent building, as applicable.40

40

Equation 5-3W=(L1 x w1 + L2 x w2 + L3 x w3 + L4 x w4)/F

L = length of a portion of exterior perimeter wallw = width of open space associated with that portion of exterior perimeter wall (Remember: must be greater than 20)F = building perimeter that fronts on a public way or open space having a width of 20 or more41

41

W=(L1 x w1 + L2 x w2 + L3 x w3 + L4 x w4)/FW = (75 x 30 + 125 x 20 + 75 x 0 + 125 x 30)/325W = (2250 + 2500 + 0 + 3750)/325W = 8500/325W = 26.15
