ABBE L6 Building Surveying Practice Questions - ABBE CBCS Level 6 Diploma in Building Surveying (ABBE, UK) Exam - ABBE L6 Building Surveying Practice Questions - ABBE CBCS Level 6 Diploma in Building Surveying (ABBE, UK) Exam

Question 1

A pre-war solid brick masonry end-terrace property exhibits stepped diagonal cracking above the ground floor bay window. The cracks are wider at the top than at the bottom. What is the most likely cause?

Thermal expansion of the brickwork facade. Sulfate attack within the lime mortar joints. Subsidence of the foundation supporting the bay window. Rust expansion of a concealed steel lintel.

Correct Answer:

Subsidence of the foundation supporting the bay window.

Question 2

During an inspection of a suspended timber ground floor, you identify extensive mycelium growth and orange-red dust-like spore deposits. What is the minimum wood moisture content required for this fungus to germinate?

12% 15% 35% 20%

Correct Answer:

20%

Question 3

An external solid brick wall shows dampness up to 1 meter above the floor. Analysis of mortar samples reveals high concentrations of both nitrates and chlorides. What does this indicate?

The dampness is rising damp from groundwater containing dissolved salts. The dampness is due to condensation deposition on cold internal plaster. A leak in the internal copper water service pipe is the sole cause. Penetrating damp from high wind-driven rain is washing out minerals.

Correct Answer:

The dampness is rising damp from groundwater containing dissolved salts.

Question 4

How does carbonation lead to the spalling of reinforced concrete lintels?

Carbon dioxide lowers the pH of the concrete, destroying the protective alkaline passivation layer around the steel reinforcement and leading to rust expansion. Carbon dioxide reacts chemically with steel to dissolve it directly into iron carbonate. Carbonation causes the aggregates to expand, producing map cracking on the surface. Carbonation increases the porosity of the concrete, allowing water to pass through like a sponge.

Correct Answer:

Carbon dioxide lowers the pH of the concrete, destroying the protective alkaline passivation layer around the steel reinforcement and leading to rust expansion.

Question 5

You observe flight holes of approximately 1mm to 2mm in diameter in a roof timber. The bore dust (frass) is cream-colored and feels gritty when rubbed between the fingers. Which insect is responsible?

Anobium punctatum (Common Furniture Beetle) Xestobium rufovillosum (Deathwatch Beetle) Hylotrupes bajulus (House Longhorn Beetle) Lyctus brunneus (Powder Post Beetle)

Correct Answer:

Anobium punctatum (Common Furniture Beetle)
