Foundation work sequence
Foundation work should move from verified levels to excavation, base preparation, reinforcement, concrete, waterproofing, drainage and controlled backfill. Skipping checks here makes every later stage more expensive.

Secuencia recomendada de trabajo
01 Set out excavation and control levels
Translate drawings into real site geometry before soil is removed.
- Mark grids, excavation edges, offsets and safe access routes.
- Check formation level against benchmark and drainage assumptions.
- Separate reusable soil, unsuitable material and disposal routes.
Punto de control: No concrete or blinding should be ordered until excavation depth, bearing condition and level records are confirmed.
Herramientas, equipos y acceso: Laser level, Excavator, Plate compactor, Measuring staff
02 Prepare base, blinding and service penetrations
Create a clean, level and coordinated base before reinforcement starts.
- Trim soft spots and compact the formation or sub-base.
- Install blinding concrete where specified to protect reinforcement and waterproofing.
- Fix sleeves and penetrations before reinforcement becomes congested.
Punto de control: Reinforcement should not start until base cleanliness, sleeves and levels are signed off.
Herramientas, equipos y acceso: Compaction tester, Concrete tools, Sleeve templates, String line
03 Place reinforcement, concrete, waterproofing and backfill
Close the foundation only after structural and water-control details are inspectable.
- Check bar spacing, laps, cover, starter bars and embedded items.
- Pour concrete with vibration, level control and curing protection.
- Apply waterproofing, drainage and protection layers before backfill.
- Backfill in layers with compaction records.
Punto de control: Do not backfill until waterproofing, drainage outlet route and hidden work photos are complete.
Herramientas, equipos y acceso: Rebar bender, Vibrator, Cover blocks, Waterproofing roller, Compactor

Consumos de material para planificaci贸n
Los consumos son referencias de planificaci贸n. Las cantidades finales deben comprobarse con planos, especificaciones, normativa local y fichas de proveedor.
| Material o recurso | Base | Rango de planificaci贸n | Unidad | Nota |
| Reinforcement steel | Concrete volume | 80-140 | kg/m3 | Concept-stage allowance only. |
| Blinding concrete | Foundation area | 0.05-0.08 | m3/m2 | Matches 50-80 mm layer. |
| Waterproofing protection board | Vertical waterproofed face | 1.05-1.15 | m2/m2 | Allows cuts and laps. |
| Compacted backfill layers | Backfill depth | 150-300 | mm/layer | Layer thickness depends on compaction equipment. |
Controles de calidad antes de avanzar
- Excavation formation, levels and bearing condition are documented.
- Sleeves and penetrations are fixed before concrete.
- Rebar cover, laps and starter bars are inspected before pour.
- Waterproofing and drainage are photographed before backfill.
