  3. Chapter 1Scope and Administration • Chapter 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.

  4. 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 KBC 2013 KBC Section 101.3 Purpose IBC text was deleted as an amendment to create this section in the 2007 edition. New text added via IBC Section 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.

  5. Except for compliance with Chapter 16, this new exception seems to exempt all industrialized buildings from compliance with all other provisions of the code. 2007 KBC 2013 KBC 102.6.1 Moved structures. Buildings and structures moved into or within … New exception added via KY amendment. 102.6.1 Moved structures.

Exception: Industrialized buildings moved into or within the jurisdiction meeting the requirements of Chapter 16 of this code.

  6. Section 104.15.7 added for clarity and better understanding as to when a mixed use building is local jurisdiction.Section 104.15.8 added to clarify exemption from local jurisdiction those buildings built on state owned property. 2007 KBC 2013 KBC 104.15.8 State-owned buildings. Buildings owned by the Commonwealth shall not be subject to local plan review, inspection or approval, regardless of size, occupant load or occupancy.

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 feet…W shall be measured perpendicular from the face of the building to the closest interior lot line.

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.

  41. Equation 5-3W=(L1 x w1+ L2 x w2+ L3 x w3+ L4 x w4)/F • L = length of a portion of exterior perimeter wall • w = 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 more

  42. 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)/325 W = 8500/325W = 26.15 w2=20” w1 = 30’ w3 = 15’ w4 = 35 ‘ Public Way Wall 2 = 125” Wall 3 = 75’ Wall 1= 75” Wall 4 = 125’

  43. Where does “W = 26.15 “ go?If = [F/P – 0.25]W/30 (F = fronting on 20’ or more – P = entire perimeter) If= [325/400 – 0.25] 26.15/30 If = [ 0.81 – 0.25] .87 If = .48 or 48% increase for open frontage w=20” w = 30’ w = 15’ w = 35 ‘ Public Way Wall 2 = 125” Wall 3 = 75’ Wall 1= 75” Wall 4 = 125’
