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.
The building code that applies in Noblesville would be Indiana Building code, which is found in Article 13.
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?
The current Indiana Building Code is based on the 2006 International Building Code (1st printing) with
Indiana Amendments.
3. Using the International Building Code, find the Use and Occupancy classification of the proposed new Keystone Building.
The Use and Occupancy classification of the newly proposed Keystone Building is 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.
Type I would be the most fire resistant and therefore the best choice for the Keystone Building.
Type II is the least fire resistant and most likely a residential type of construction
Type III is slightly better than Type II.
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.
The least restrictive construction type is Type I A, which is unlimited. Yes a fire-protective layer is required for the structural elements.
6. What materials do you propose to use for the new interior walls and floor for the Keystone Building? Justify your answer.
I would suggest brick walls for the interior walls or steel beams for the interior structure walls and for the floor linoleum or marble.
7. Use the IBC to determine the Occupant Load (IBC 2009 Section 1004) for the Keystone Building assuming a second floor is added per the Keystone Library Renovation Preliminary Building plans (see Revit file). 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.
The first floor of the Keystone Library has an occupant load of about 178 people. The second floor is approximately 46 people, and the green roof is also 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.
The total egress for stairways should be about 113.5 inches, and other means of egress would be about 89 inches.
9. What is the minimum number of exits required for the Occupant Load (IBC 2009 Section 1021)
The minimum number of exits required for the Keystone Building is 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 is not permissible. The building must have 2 exits per story.
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.)
The zoning designation that applies to the Keystone Building property is the planned business designation.
12. Describe the purpose of this zoning designation. Document your answer with a section number from the code.
The purpose of the Business designation is primarily for larger scale buildings, specifically for commercial uses.
13. What is the minimum lot size within this designation? Does the Keystone Property meet this requirement? Document your answer with a section number of the code.
The minimum lot size of this designation is 20,000 square feet according to the Sumarry of Commercial Bulk Requirements table.
14. What is the maximum building height according to the Noblesville ordinance?
The maximum building height is stories or approximately 35 feet.
15. Read Section 159.120 of the Noblesville Code of Ordinances. Record any information that is important to the redevelopment of the Keystone building.
