Activity 3.1.2 Land Use and Development Regulations

1.    Identify the Building Code that applies in Noblesville by reviewing Section 154.04 Adoption of Rules by Reference in the Noblesville Code of Ordinances.  
Fire and Building Safety Standards, Indiana Building Code, Indiana Building Code Standards, Indiana Handicapped Accessibility Code.

2.    Visit the Indiana Association of Building Officials website at http://www.iabo.com/ and follow the link to Current Codes. On which model code is the current Indiana Building Code based?
International Buidling Code
3.    Using the International Building Code, find the Use and Occupancy classification of the proposed new Keystone Building.
Assembly, A-4.
4.    Using the International Building Code, describe each of the four types of construction. Based on the existing structure, under which of these types of construction could the Keystone Building fall? See section 503.1.
I
II
III
IV
V
Types I and II construction are those types of construction in which the building elements are of noncombustible materials, except as permitted in Section 603 and elsewhere in this code. Type III construction is that type of construction in which the exterior walls are of noncombustible materials and the interior building elements are of any material permitted by this code, Fire-retardant-treated wood framing. Type IV construction (Heavy Timber, HT) is that type of construction in which the exterior walls are of noncombustible materials and the interior building elements are of solid or laminated wood without concealed spaces.  Type V construction is that type of construction in which the structural elements, exterior walls and interior walls are of any materials permitted by this code.
5.    Compare the allowable Building Heights and Areas (IBC 2009 Table 503) for the Keystone Library using different construction types. What is the least restrictive construction type that can be used for the Keystone Library? Is a fire-protective layer required over the structural elements? Note: The letter A indicates that the structural members are protected by a fire-rated coating or cover (sheetrock, spray on, or another approved method). The letter B indicates that the structural members are not protected by an additional fire-rated coating or cover.
Type I is the least restrictive, but isnt the most practical for a library so either Type II or IV which allow the same amount for area and floors. Yes a fire-protective layer is required over the structural elements.  I
6.    What materials do you propose to use for the new interior walls and floor for the Keystone Building? Justify your answer.
Walls made of laminated fire retardant wood over aluminum framing.
7.    Use the IBC to determine the Occupant Load (IBC 2009 Section 1004) for the Keystone Building assuming a second floor is added. For now, conservatively assume that the second floor is entirely stacks and that the first floor is entirely reading rooms. In addition, because there is currently no plan to include an outside stairway to the roof, assume that the occupants of the green roof must exit through the 2nd floor. The building inspector has determined, based on the planned use of the green roof as additional reading area, that the occupant load for the green roof may be based on the requirements for reading rooms.
First floor approximately 178 people.
Second floor approximately 46 people.
Green roof approximately 178 people.
8.    The occupant load is used to determine the minimum egress width for the building. Use the IBC to determine the required total egress width (IBC 2009 Section 1005) for the Keystone Building including the second floor.
For stairways 113.5 inches.
For other means of egress 89 inches.
9.    What is the minimum number of exits required for the Occupant Load (IBC 2009 Section 1021)?
2 exits
10. Read IBC 2009 Section 1021.2. Is it permissible to have only a single exit from the ground floor? From the second floor? Justify your answers.
No it must have at least 2 exits per story.
The answers to the following questions should be researched in the Noblesville Code of Ordinances and the Noblesville Zoning Map.

11. In which zoning designation does the Keystone building property lie? (Refer to the Keystone Library Site Location Map to help locate the site on the zoning map.)
Planned business
12. Describe the purpose of this zoning designation. Document your answer with a section number from the code.
For larger scale buildings used for commercial purposes.
14. What is the maximum building height according to the Noblesville ordinance?
On buildings up to three stories in height, building-mounted signage shall not exceed two feet in height. On buildings over three stories in height, building-mounted signage shall not exceed three feet in height, with the exception in the Internal Subdistrict where they shall not exceed two feet in height
