Locating quota sub-items for earth backfill, replacement-subgrade, and muck loading/hauling in Beijing DB11/T 2382-2024

Topic Positioning

Chapter attribution and sub-item location within Appendix A of Beijing's DB11/T 2382-2024 Consumption Standard for Construction Works for earth backfill, replacement subgrade, and muck loading/hauling — for quickly locating sub-items when compiling Beijing budgets/prices.

Core Conclusions

Replacement fill (ground-treatment chapter) — Table A.2.1-1 replacement subgrade:

• A-2-1 manual sand-gravel fill (m3), work content: "1. Layered spreading, leveling, compaction (rolling). 2. Dozer pushing sand, sand filling, rolling." Consumption: composite labor class II 0.2000 workdays; natural sand-gravel 2315.4000 kg; electric rammer 250 Nm 0.0250 shifts; other materials 1.0%; other tools 1.5%.
• A-2-3 spreading sand (stone chips) (m3), work content: "layered spreading, leveling, compaction." Consumption: composite labor class II 0.2930 workdays; sand 1787.6000 kg; electric rammer 250 Nm 0.0167 shifts; other materials 1.0%; other tools 1.5%.

Backfill (earthworks chapter) — A.1.3 backfill:

• A-1-42 indoor backfill (m3, continuation of Table A.1.3-1 foundation backfill), work content: "backfill, leveling, compaction." Consumption: composite labor class III 0.2050 workdays; frog rammer 0.0490 shifts; other tools 1.5%.

Site backfill and loading/hauling — A.1.3-2 site backfill, A.1.4-1 earth (rock) haulage:

• A-1-51 soil loading, haul within 1 km (m3), work content: "1. Mechanical loading with manual cleanup. 2. Haul, unload, dispose." Consumption: spoil/muck disposal 1.0000 m3; 12 t dump truck 0.0041 shifts.
• A-1-54 rock (muck) and spoil loading, haul within 1 km (m3), same work content; consumption: spoil/muck disposal 1.0000 m3; 12 t dump truck 0.0057 shifts.

Chapter attribution matches the BOQ caliber: replacement fill sits in the ground-treatment chapter, backfill in the earthworks chapter; haul sub-items already include disposal material, so no separate disposal cost item is needed in price assembly.

Applicable Boundaries

Applies to compiling Beijing building budgets and price assembly under DB11/T 2382-2024; the above consumptions are standard values — convert per the standard's notes where actual conditions or work content mismatch; measurement calibers (cut/fill/haul all by drawing volume, no loose-coefficient multiplication) are covered in related cards and must not be mixed with consumptions. Haul beyond the base tier follows the "each additional 1 km" stacking rule.
