👉Building Finishes, Services Coordination & Defect Management (Practical & Technical)
1. Why are building finishes important in construction projects?
They protect structural elements, improve durability, functionality, and enhance aesthetics.
2. What checks are required before starting plastering works?
Surface cleaning, alignment check, proper curing of masonry, service concealment completion, and approval.
3. What is the standard thickness of internal and external plaster?
Internal: 12–15 mm
External: 15–20 mm (often in two coats).
4. What causes cracks in plaster and how are they controlled?
Shrinkage, poor mix, improper curing, and thermal movement; controlled by proper mix, curing, and mesh at junctions.
5. What is the purpose of expansion or control joints in buildings?
To accommodate movement and prevent random cracking.
6. What checks are required before floor screeding?
Surface cleanliness, level marking, correct slope, service completion, and material approval.
7. What is the recommended screed thickness for building floors?
Typically 40–50 mm for bonded screed unless otherwise specified.
8. What are the key quality checks for tiling works?
Tile alignment, joint spacing, level, slope to drain, adhesive coverage, and grout quality.
9. What causes tile debonding or hollow sound?
Poor surface preparation, insufficient adhesive, movement, or moisture ingress.
10. What is waterproofing and where is it critical in buildings?
Protection against water penetration; critical in toilets, kitchens, roofs, basements, and balconies.
11. What are common waterproofing systems used in buildings?
Cementitious coating, bituminous membrane, liquid-applied membranes, and PVC membranes.
12. What tests are conducted after waterproofing application?
Flood (ponding) test for 24–72 hours and visual inspection.
13. What coordination checks are required between civil and MEP works?
Pipe routing, sleeves, conduits, access panels, and service clearances.
14. What is snag list in building projects?
A documented list of defects and incomplete works prepared before handover.
15. What is rectification period?
The time allowed to correct identified defects before final acceptance.
16. What are common finishing defects in buildings?
Uneven plaster, paint peeling, leakage, cracked tiles, and misaligned fixtures.
17. How do you manage defects during finishing stage?
Inspection, documentation, assignment, rectification, and re-inspection.
18. What documents are required for final building handover?
As-built drawings, test reports, warranties, O&M manuals, and completion certificate.
19. What is preventive maintenance in building projects?
Planned inspections and minor repairs to extend service life.
20. What records should be maintained for building finishes and defects?
Inspection reports, snag lists, rectification logs, test results, and handover documents.
