Denver General Building Contractor (A) Exam (ICC F11, 2015 IBC)

A 'mark' is an identification applied by the manufacturer giving the manufacturer's name and the function of the product, while a 'label' additionally carries performance characteristics and the identification of an approved agency, and a 'manufacturer's designation' indicates compliance with a specified standard or set of rules.

'Facility' covers all or any portion of buildings, structures, site improvements, elements and pedestrian or vehicular routes located on a site, whereas 'Lot' is a portion or parcel of land considered as a unit, 'Structure' is that which is built or constructed, and 'Building' is any structure used or intended for supporting or sheltering any use or occupancy.

Occupant load of booths is one person for each 24 inches of booth seat length measured at the backrest, while fixed seating without dividing arms is computed at not less than one person for each 18 inches of seating length (IBC 1004.4).

Table 509 requires an incinerator room to have BOTH a 2-hour separation AND an automatic sprinkler system, while furnace rooms and refrigerant machinery rooms require 1 hour OR sprinklers.

Per IBC 2304.12.1.1, joists or structural floors closer than 18 inches to exposed ground must be naturally durable or preservative-treated, while for girders the threshold is closer than 12 inches.

Per IBC 2304.5, combustible framing must be not less than 2 inches from flues, chimneys and fireplaces, but 6 inches from flue openings specifically.

IBC 1005.3.1 computes stairway capacity at 0.3 inch per occupant; the reduced 0.2-inch factor applies only to buildings (other than Groups H and I-2) equipped throughout with an automatic sprinkler system AND an emergency voice/alarm communication system.

IBC 1020.4 limits dead ends to 20 feet where more than one exit or exit access doorway is required (unsprinklered base limit); Exception 2 permits up to 50 feet in Groups B, E, F, I-1, M, R-1, R-2, R-4, S and U where the building is sprinklered throughout per 903.3.1.1 (the Group I-3 Condition 2, 3 or 4 50-foot allowance is a separate exception).

IBC 1009.3 requires 48 inches clear between handrails for a stairway serving as part of an accessible means of egress (Exception 2 waives it where the building is sprinklered throughout), while 44 inches is only the general minimum stairway width of Section 1011.2 and does not override a larger required capacity.

Noncircular Type I handrails under §1014.3.1 have a perimeter of not less than 4 inches and not greater than 6-1/4 inches, while a handrail with a perimeter greater than 6-1/4 inches is Type II and must provide a graspable finger recess on both sides of the profile.

IBC 1014.2 requires uniform handrail height of not less than 34 and not more than 38 inches above stair tread nosings or ramp finish surface; the 30-to-34-inch range applies only to alternating tread devices and ships ladders.

Per IBC 102.1, where a general requirement conflicts with a specific requirement for the same condition, the specific requirement governs; the 'most restrictive governs' rule applies instead where different sections specify different materials, methods of construction or other requirements for the same case.

Per the Concrete Manual §4.2, Type V sulfate-resistant cement is used for severe sulfate exposure and Type II for moderate exposure; Type III is a high-early-strength cement, not sulfate-resisting.

Before use, fire-retardant-treated wood must be dried to 19% or less moisture content for lumber and 15% or less for wood structural panels.
