SMSTS Quality Control Procedures 2 — Questions and Answers
Question 1: Under SMSTS, what is the primary purpose of a quality control inspection checklist on a construction site?
- To satisfy insurance requirements only
- To provide a systematic framework for verifying work meets specified standards (Correct answer)
- To assign blame when defects occur
- To replace the need for a site manager
Correct answer: To provide a systematic framework for verifying work meets specified standards
Checklists provide a systematic, repeatable framework ensuring all quality criteria are consistently verified against project specifications.
Question 2: A sub-contractor completes formwork that deviates from the engineer's drawing tolerances. What is the FIRST action a site manager should take?
- Proceed with concrete pour and document the deviation
- Issue a non-conformance report and halt the pour until resolved (Correct answer)
- Notify the client and wait for their decision
- Demolish all formwork immediately
Correct answer: Issue a non-conformance report and halt the pour until resolved
A non-conformance report must be raised and work stopped to prevent embedding a defect that would be costly or impossible to rectify after concreting.
Question 3: Which document records all identified defects, their status, and corrective actions taken on a construction project?
- Method statement
- Defect register (snagging list) (Correct answer)
- Risk assessment
- Programme of works
Correct answer: Defect register (snagging list)
A defect register (snagging list) is the formal record tracking each defect, its resolution status, and the responsible party for correction.
Question 4: Concrete cube tests are taken on site primarily to:
- Estimate the cost of concrete supply
- Verify the delivered concrete achieves the specified compressive strength (Correct answer)
- Determine the water content for mixing
- Satisfy Health and Safety Executive reporting requirements
Correct answer: Verify the delivered concrete achieves the specified compressive strength
Cube tests are crushed at 7 and 28 days to confirm the concrete batch meets the design compressive strength before loading the structure.
Question 5: What does 'hold point' mean in a quality inspection plan (ITP)?
- A pause in the construction programme due to bad weather
- A stage at which work must stop until an authorized inspection is completed and approved (Correct answer)
- A contractual milestone for payment
- A safety briefing point for operatives
Correct answer: A stage at which work must stop until an authorized inspection is completed and approved
A hold point requires work to halt and a designated authority to inspect and sign off before any further construction activity proceeds.
Question 6: Which British Standard governs the specification for concrete production and conformity?
- BS 8000
- BS EN 206 (Correct answer)
- BS 5975
- BS 7671
Correct answer: BS EN 206
BS EN 206 specifies requirements for concrete production, including constituent materials, properties, and conformity criteria.
Question 7: On an SMSTS-managed site, who is ultimately responsible for ensuring quality control procedures are implemented?
- The client's representative
- The site manager (Correct answer)
- Each individual operative
- The local authority building control officer
Correct answer: The site manager
The site manager holds ultimate responsibility for implementing and enforcing the project's quality control procedures on a day-to-day basis.
