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.
It is the Indiana Building 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?
It is based off of the 2006 version.

3. Using the International Building Code, find the Use and Occupancy classification of the proposed new Keystone Building.
The classification of the new Keystone Building is A-3.

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.
Types I and II construction are those types of construction in which the building elements listed in Table 601 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 shall be permitted within exterior wall assemblies of a 2-hour rating or less
Type IV construction uses heavy timber and is the 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.
I believe that the building could fall into almost any category except a Type IV building.

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 V construction would be the least restricted because you can use any thing.
6. What materials do you propose to use for the new interior walls and floor for the Keystone Building? Justify your answer.
I propose having a tile floor and wooden walls. The tile floors would reduce the probability of a fire and a wood wall can be reused when they tear down the building in later years.
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.
For the bottom floor you can have an occupancy of 187 people. For the second floor you can have an occupancy of 47 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 minimum egress width fo rthe building is 47 inches.
9. What is the minimum number of exits required for the Occupant Load (IBC 2009 Section 1021)?
The minimum number of exits is two.
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.
