For a fresh Quantity Surveying (QS) student, stepping onto a construction site can feel overwhelming. Soil is being dug, concrete is poured, workers move in rhythm — and behind it all, the QS must capture every activity in numbers.
This is where the take-off list comes in. It is the QS’s roadmap, breaking down construction into measurable parts. Think of it as the script of a play: every act (excavation, roofing, finishes) must be listed, measured, and priced. Without it, the project risks drifting into chaos.
Stage 1: Preliminaries — Setting the Stage
Before construction begins, the site must be prepared.
- Site survey and setting out: marking boundaries and levels.
- Clearing site: removing vegetation, debris, or old structures.
- Temporary works: site office, storage sheds, toilets, fencing.
- Utilities setup: water and electricity supply for construction.
Units to measure: lump sum (LS), square meters (m²) for clearing, number (nr) for temporary facilities.
Stage 2: Earthworks and Substructure — Digging Deep
This is the foundation of the building.
- Excavation: trenches, pits, bulk earth removal.
- Foundation concrete: blinding, strip/pad foundations, raft.
- Reinforcement steel: cut, bend, fix.
- Formwork: shaping concrete.
- Backfilling and compaction: restoring soil stability.
Units to measure: cubic meters (m³) for excavation, kilograms (kg) for reinforcement, square meters (m²) for formwork.
Stage 3: Superstructure — Raising the Skeleton
The building begins to rise above ground.
- Columns, beams, slabs: concrete, reinforcement, formwork.
- Walls: block or brick masonry.
- Staircases: structural connections between floors.
Units to measure: m³ for concrete, m² for walls, nr for staircases.
Stage 4: Roofing — Crowning Glory
The roof completes the skeleton.
- Roof trusses: timber or steel.
- Roof covering: tiles, sheets, shingles.
- Rainwater goods: gutters, downpipes, fascia boards.
Units to measure: m² for roof covering, m for gutters, nr for trusses.
Stage 5: Finishes — Dressing the Building
This stage gives the building its personality.
- Plastering: smooth walls.
- Flooring: tiles, screed, terrazzo, wood.
- Painting and decorating: internal and external.
- Ceilings: gypsum, POP, timber.
Units to measure: m² for plastering, flooring, and ceilings.
Stage 6: Windows and Doors — Openings to the World
Every building needs access and light.
- Windows: frames and glazing.
- Doors: frames, panels, locks.
- Ironmongery: hinges, handles, bolts.
Units to measure: nr (number of items).
Stage 7: Services — Bringing the Building to Life
Without services, a building is just a shell.
- Plumbing: pipes, fittings, sanitary fixtures.
- Electrical: wiring, switches, sockets, lighting.
- Mechanical systems: HVAC, fire protection.
Units to measure: m for pipes and wires, nr for fixtures.
Stage 8: External Works — Completing the Picture
The outside environment matters too.
- Paving: walkways, driveways.
- Drainage: stormwater, septic, soakaway.
- Boundary walls and gates: fencing, security.
- Landscaping: plants, lawns, trees.
Units to measure: m² for paving, m for fencing, nr for gates and trees.
Stage 9: Final Activities — Curtain Call
The building is tested, cleaned, and handed over.
- Testing and commissioning: plumbing, electrical systems.
- Snagging: fixing defects.
- Final cleaning: preparing for handover.
Units to measure: lump sum (LS).

Closing Thought
As a QS student, remember: the take-off list is your storybook of construction. Each line item is a sentence, each unit is a word, and together they narrate the journey from bare soil to a finished building.
The more detailed your list, the clearer your BOQ, and the stronger your role as the quiet narrator behind the rise of every structure.
