Sample ABBE L6 Building Surveying Practice Questions

Try these sample questions to test your ABBE L6 Building Surveying exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 110+ question experience with AI tutoring.

1A 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?

A.Thermal expansion of the brickwork facade.

B.Sulfate attack within the lime mortar joints.

C.Subsidence of the foundation supporting the bay window.

D.Rust expansion of a concealed steel lintel.

Explanation: Cracking that is wider at the top than the bottom indicates downward rotational movement (subsidence) of that section of the building. Bay windows are often built on shallower foundations than the main house, making them highly susceptible to movement.

2During 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?

A.12%

B.15%

C.35%

D.20%

Explanation: The orange-red spores and mycelium are characteristic of Serpula lacrymans (dry rot). While dry rot prefers moisture levels around 30% to 40% for rapid growth, it can germinate and survive at a minimum wood moisture content of approximately 20%.

3An 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?

A.The dampness is rising damp from groundwater containing dissolved salts.

B.The dampness is due to condensation deposition on cold internal plaster.

C.A leak in the internal copper water service pipe is the sole cause.

D.Penetrating damp from high wind-driven rain is washing out minerals.

Explanation: Nitrates and chlorides are hygroscopic salts commonly found in ground soil. Their presence at lower wall levels confirms that groundwater has been drawn up by capillary action (rising damp), leaving salt bands behind as the water evaporates.

4How does carbonation lead to the spalling of reinforced concrete lintels?

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

B.Carbon dioxide reacts chemically with steel to dissolve it directly into iron carbonate.

C.Carbonation causes the aggregates to expand, producing map cracking on the surface.

D.Carbonation increases the porosity of the concrete, allowing water to pass through like a sponge.

Explanation: Concrete is naturally alkaline (pH 12-13), which protects steel rebar from rusting (passivation). Carbon dioxide reacts with calcium hydroxide to form calcium carbonate, lowering the pH below 9. This destroys the passivation layer, allowing the steel to rust, expand, and spall the concrete.

5You 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?

A.Anobium punctatum (Common Furniture Beetle)

B.Xestobium rufovillosum (Deathwatch Beetle)

C.Hylotrupes bajulus (House Longhorn Beetle)

D.Lyctus brunneus (Powder Post Beetle)

Explanation: Anobium punctatum creates 1-2mm circular flight holes and leaves ellipsoid, gritty frass. Deathwatch beetle holes are larger (3mm) with bun-shaped frass, and House Longhorn creates large oval holes (6-10mm).

6Black mold (Stachybotrys chartarum) is found concentrated strictly along the top corner of an external wall where it meets the ceiling. The rest of the wall is dry. What is the most likely cause?

A.A slow puncture leak in the heating pipes within the floor above.

B.A thermal bridge at the wall-to-ceiling junction causing localized condensation.

C.Defective guttering allowing water penetration through the brickwork.

D.Rising damp reaching its maximum vertical height limit.

Explanation: Wall-to-ceiling junctions are prone to thermal bridging because insulation is often compressed or missing at the eaves. The cold surface temperature leads to localized condensation, providing the moisture needed for mold to grow.

7An external brick chimney stack built in the 1970s shows horizontal cracking and bowing along its length, particularly on the south-facing side. What chemical pathology is likely occurring?

A.Rust expansion of the flue liner support brackets.

B.Alkali-silica reaction within the clay brick clay mix.

C.Thermal shock from rapid flue heating during winter.

D.Sulfate attack in the mortar due to reactions between flue gas condensates, moisture, and ordinary Portland cement.

Explanation: Sulfate attack occurs in wet brickwork (like unlined chimneys) when sulfates from flue gases or bricks react with tricalcium aluminate in Portland cement mortar. This forms calcium sulfoaluminate (ettringite), which expands and causes cracking and bowing.

8During a level 3 building survey of a 1930s cavity wall property, you note horizontal cracks in the mortar joints every 5 to 6 courses and slight bowing of the external leaf. What is the likely cause?

A.Corrosion and expansion of mild steel wall ties.

B.Inadequate cavity ventilation causing moisture build-up.

C.Thermal expansion of the inner blockwork leaf.

D.The use of weak lime-based mortar in the cavity wall construction.

Explanation: Older wall ties were made of ungalvanized or poorly galvanized mild steel. As they rust, they expand to several times their original thickness. This expansion lifts the mortar joints, causing horizontal cracking at regular intervals and bowing of the outer leaf.

9A slate roof exhibits numerous slipped slates, and close inspection reveals that the nail heads have eaten through the slate holes, or the nails themselves have rusted away. What is this condition commonly called?

A.Slate delamination

B.Nail sickness

C.Roof spread

D.Sulfate decay

Explanation: Nail sickness occurs when the metal nails fixing the slates (often iron or low-quality alloy) corrode over time. The nails fail, or the rust expands and enlarges the nail holes, causing the slates to slip out of position.

10A roof void shows widespread condensation on the underside of the roofing felt. There are no pipe leaks, and the ceiling below is well-insulated. What is the primary cause?

A.The ceiling insulation is too thin, allowing cold air to sink.

B.Lack of high and low-level roof ventilation combined with a non-breathable roofing felt.

C.The roof pitch is too steep, causing rapid cooling of the slates.

D.The roof tiles have become porous and are letting rainwater through.

Explanation: Without soffit, fascia, or ridge vents, moisture migrating from the living space below becomes trapped in the cold roof void. If the underlay is non-breathable (bitumen felt), this moisture condenses on its cold surface.

About the ABBE L6 Building Surveying Exam

The ABBE Level 6 Diploma in Building Surveying is a professional qualification designed for individuals seeking to become competent building surveyors.

Frequently Asked Questions

What is the ABBE Level 6 Diploma in Building Surveying?

It is a vocational qualification at FHEQ Level 6 (degree standard) accredited by the Awarding Body for the Built Environment (ABBE). It is designed to train residential or commercial surveyors, providing them with the professional knowledge required to practice and gain direct entry to AssocRICS.

Does this qualification lead to RICS membership?

Yes, completing this diploma provides direct entry to the Associate assessment (AssocRICS) with the Royal Institution of Chartered Surveyors under the Building Surveying pathway, bypassing standard academic degree requirements.

What topics are covered in the building surveying exams?

The assessments cover four core domains: building pathology (defect analysis, moisture, rot, movement), construction technology (building elements, services, sustainability), contract administration (forms of contract, tendering, valuations), and building law (Building Regulations, CDM 2015, Party Wall Act).

How is the course assessed?

The qualification is assessed using a combination of a comprehensive coursework portfolio (detailing practical building inspections and academic research) and closed-book written or multiple-choice examinations administered by approved training centres.

What are the entry prerequisites?

There are no formal academic entry requirements. However, having a background in construction, estate agency, property management, or holding a relevant Level 3/4 qualification is highly beneficial due to the technical nature of the material.
