What is the purpose of 'weep holes' in masonry cavity walls?
Answer: To drain water that infiltrates the cavity back to the exterior
Weep holes at the base of cavity walls allow any water that enters the cavity to drain out, preventing moisture accumulation and damage.
In electrical systems, what does 'voltage drop' refer to and why is it significant in building design?
Answer: The reduction in voltage along a conductor due to resistance, affecting equipment performance
Voltage drop along conductors reduces available voltage at equipment, causing motors, lights, and electronics to underperform or fail; NEC limits it to 3% for feeders.
What is the 'wet-bulb temperature' used for in building mechanical systems?
Answer: Determining the moisture content of air for cooling coil and cooling tower sizing
Wet-bulb temperature accounts for evaporative cooling and directly indicates air's moisture content, critical for sizing cooling equipment and evaluating heat stress.
Which building code provision governs egress stair width requirements in the US?
Answer: IBC Chapter 10
IBC Chapter 10 covers means of egress, including minimum stair widths based on occupant load and occupancy classification.
What is a 'curtain wall' system in high-rise construction?
Answer: A non-structural exterior cladding system that transfers its own weight to the building frame
Curtain walls are lightweight, non-load-bearing exterior facade systems attached to the structural frame, carrying only their own weight and transferring wind loads to the structure.
What is the primary structural difference between a 'one-way slab' and a 'two-way slab'?
Answer: One-way slabs span primarily in one direction; two-way slabs span and distribute loads in both directions
One-way slabs with aspect ratios above 2:1 span predominantly in the short direction; two-way slabs with more square panels engage reinforcement in both directions.
In building commissioning, what is the goal of 'functional performance testing'?
Answer: To confirm that installed building systems operate according to the owner's project requirements
Functional performance testing verifies that HVAC, electrical, plumbing, and other systems operate as intended under various conditions before owner occupancy.
