An inspector in a basement observes a steel support column (lally column) that is not perfectly vertical and shows significant rust and flaking at its base. This condition should be reported as a defect PRIMARILY because:
- A. The column is undersized for the beam it is supporting.
- B. The rust is a cosmetic issue but should be painted.
- C. The concrete floor is likely cracked beneath the column's base plate.
- D. The lean indicates a potential shift in load, and corrosion can significantly reduce the column's load-bearing capacity.
Answer: D. The lean indicates a potential shift in load, and corrosion can significantly reduce the column's load-bearing capacity.
A leaning or tilted steel column indicates a potential shift in the foundation or the load it supports, which is a serious structural concern. Furthermore, significant rust and flaking, especially at the base where moisture often collects, can severely weaken the steel and compromise its structural integrity and load-bearing capacity, potentially leading to collapse.
When inspecting a forced-air furnace system, an inspector notes that the metal flue pipe has a horizontal run of 8 feet before it enters the chimney. For proper drafting of exhaust gases, this horizontal pipe should:
- A. Be perfectly level to ensure even flow
- B. Have a downward slope away from the chimney
- C. Have a continuous upward slope towards the chimney
- D. Be insulated to maintain high gas velocity
Answer: C. Have a continuous upward slope towards the chimney
The flue vent for a standard-efficiency furnace must have a continuous upward slope from the furnace to the chimney, typically a minimum of 1/4 inch per foot of horizontal run. This upward slope helps the hot, buoyant exhaust gases to vent naturally and prevents condensation from running back into the furnace.
A home inspector notices the furnace flue pipe has a downward slope toward the furnace. What is the concern?
- A. It reduces heating efficiency only
- B. Combustion gases may backdraft into the living space
- C. The pipe will overheat and warp
- D. Condensation will damage the heat exchanger
Answer: B. Combustion gases may backdraft into the living space
Flue pipes must slope upward (minimum 1/4 inch per foot) toward the chimney so combustion gases draft properly and do not back-flow into the home.
What is 'blocking' between floor joists primarily intended to accomplish in structural framing?
- A. Prevent joists from rotating or twisting (lateral buckling) and transfer loads between joists
- B. Provide nailing surface for subfloor panels at the perimeter only
- C. Increase the fire rating of the floor assembly
- D. Allow plumbing pipes to penetrate the floor without cutting joists
Answer: A. Prevent joists from rotating or twisting (lateral buckling) and transfer loads between joists
Solid blocking or bridging between joists prevents lateral rotation, distributes point loads across multiple joists, and stiffens the floor system.
