Pricing归属 of foundation probing (rod probing/tamping) in Beijing: already综合 in the manual-excavation item work contents, not itemized separately

Topic Positioning

The norm-pricing归属 and placement of foundation probing (rod probing and bottom tamping) in Beijing: no separate item — included in the manual-excavation item work contents and priced with foundation earthwork.

Core Conclusions

1. Basis (DB11/T 2382-2024, 4.2.2):

• (1) "Manual excavation consumption shall be determined by soil class and shall include rod probing and bottom tamping";
• (3) "Machine-excavation items preferably exclude hand trimming of the trench/pit bottom; hand trimming consumption may use the manual excavation items". Hence probing (rod probing) is not a new item; its cost sits in the selected manual digging/pit items.

2. Item evidence: building volume A-1-19 "manual pit excavation, soil class I-II" (m3) work content "dig, haul, trim edges, rod probing and tamping", consumption includes electric probing machine 0.0039 shifts; Beijing 2021 item 1-5 "manual excavation, soil class I-II" likewise includes 0.0039 shifts. Neither edition sets a standalone "probing" item — same caliber.
3. Machine-dig projects: hand base trimming uses the manual items (4.2.2(3)); the reserved hand-trim depth is preferably 300mm where the drawings are silent (4.2.15(2)) — that manual item already includes probing/tamping.
4. BOQ side (GB/T 50854-2024 Annex A): base probing is a characteristic of the earthwork BOQ item — "the 'base treatment method' characteristic may describe base compaction, base probing, etc." — not an independent code.
5. If separate listing is unavoidable (subcontract caliber): Beijing has no standalone item — a missing-item case; analyze via a supplementary unit-price estimate and avoid double pricing with the manual items (which already include probing/tamping).

Applicable Boundaries

• Beijing pricing caliber (DB11/T 2382-2024 consistent with 2021) for probing within building/decoration earthwork items.
• Across volumes (municipal, landscape) or industries (railway, highway), check the specific item work contents — do not transplant this caliber.
• Premise: probing per drawings and acceptance codes; special design/contract requirements govern.
• No unit prices here — price per market at compilation.

Further Reading

• DB11/T 2382-2024 Section 4.2: 4.2.2 (manual/machine item setup, probing/tamping), 4.2.15 (base areas, depths, slope increments; 300mm hand trim; Tables 4.2.15-1/-2).
• Annex A item A-1-19 (Table A.1.1-3) work content and consumption.
• GB/T 50854-2024 Annex A "base treatment method" characteristic provisions.
• Beijing 2021 item 1-5 cross-check.
