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?
Indiana Building Code, 2003 Edition (IBC, 2000 Edition) CABO/ANSI A117.1-1992
3. Using the International Building Code, find the Use and Occupancy classification of the proposed new Keystone Building.
A-3
Assembly uses intended for worship, recreation or amusement and other
assembly uses not classified elsewhere in Group A
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. 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. 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 complying
with Section
2303.2
shall be permitted within exterior wall assemblies of a 2-hour rating or
less.
Type IV. 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. The details of
Type IV construction shall comply with the provisions of this section.
Fire-retardant-treated wood framing complying with Section
2303.2
shall be permitted within exterior wall assemblies with a 2-hour rating or less.
Minimum solid sawn nominal dimensions are required for structures built using
Type IV construction (HT). For glued-laminated members the equivalent net
finished width and depths corresponding to the minimum nominal width and depths
of solid sawn lumber are required as specified in Table
602.4.
Type V. 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.
The keystone building will most
likely fall in type IV
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
contruction type that can be used in type V-A because it can be built out of
anything. No fire protective layer is required.
6. What materials do you propose to use for the new interior walls and floor for the Keystone Building? Justify your answer.
A variety of materials
would be acceptable due to the fact that the outside is made of brick, and also
the fact that it has steel supports. I personally would choose wood and drywall
because it is inexpensive and easy.
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.
Reading room 178, Stacks 47
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.
47" is the minimum
width of egress for the building
9. What is the minimum number of exits required for the Occupant Load (IBC 2009 Section 1021)?
4 exits is the minumum number required in accordance to
the occupant load
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.
The answers to the following questions should be researched in the Noblesville Code of Ordinances and the Noblesville Zoning Map.
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.)
Planned business
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.
A.) Allowable Use of Land and
Building.(B) Property Access. Every
building hereafter erected or moved shall be located on a lot with frontage and
access on a street, and provide for safe and convenient access, fire protection,
and required off-street parking, except as otherwise provided in § 159.107(C).
(C) Number of Buildings Per Lot. Every building hereafter erected shall be located on a lot unless otherwise specified for planned developments. In no case shall there be more than one principal building used for residential purposes, and its accessory buildings, located on one lot, except as otherwise provided in this chapter for a mobile home park or planned development. If two or more principal non-residential buildings are located on a lot, the space between such buildings shall be as established by the yard setback requirements of the district in which the use is located.
(C) Number of Buildings Per Lot. Every building hereafter erected shall be located on a lot unless otherwise specified for planned developments.
