Beijing 2024 consumption standard (DB11/T 2382-2024) waterproof mortar: sub-item selection cross-referenced by position and method - roof A-9-83/84/85/89, walls A-9-166/167, floors A-9-209

Topic Positioning

This card gives, for the waterproof-mortar (rigid waterproofing / SF polymer waterproof mortar) sub-items of Chapter A.9 "Roofing and Waterproofing Works" of Appendix A "Building and Decoration Works" of the Beijing 2024 "Construction Consumption Standard" (DB11/T 2382-2024): the selection cross-reference by position and by method, the main labor/material/machinery consumptions, and the 2021-edition number cross-reference - for use when compiling construction-drawing budgets, maximum bid price limits and cost estimates in the Beijing area.

Wall (same table)	SF polymer waterproof mortar	A-9-167	Waterproof mortar	Comprehensive labor Cat. II 0.0740 work-days; SF polymer waterproof mortar 0.0210; other materials 1.5%
Floor (Table A.9.4-3 floor mortar waterproofing)	Waterproof mortar with waterproofing agent	A-9-209	Waterproof mortar	Comprehensive labor Cat. II 0.0700 work-days; dry-mixed floor screed mortar 0.0204, waterproofing agent 0.5610; other materials 1.5%

Each sub-item also contains "other machinery and tools" at 2.0%. Codes of the main labor/material/machinery items: SF polymer waterproof mortar (800700030001), waterproofing agent (143500030000), galvanized wire mesh (800100010900), cementitious capillary crystalline agent (133900160000), dry-mixed rendering mortar DP M10 (800100011000), dry-mixed floor screed mortar (800100210000), comprehensive labor Category II (000105010000).

(II) Key points of application

1. First by position, then by method: roof, wall and floor each have dedicated sub-items and they must not be applied across positions (e.g. wall waterproof mortar must not use roof sub-item A-9-84). In the standard, "rigid waterproofing" falls on the waterproof mortar / waterproof concrete sub-items within the roof rigid-waterproofing table (A-9-83 to A-9-85, A-9-89).
2. The three material methods are independent sub-items with different material compositions and are not interchangeable: the with-waterproofing-agent type (A-9-84/166/209, consuming dry-mixed mortar + waterproofing agent, the roof items additionally containing galvanized wire mesh); the SF polymer type (A-9-83/167, consuming finished SF polymer waterproof mortar); the cementitious capillary crystalline type (A-9-85, consuming capillary crystalline agent + galvanized wire mesh). Apply according to the design description.
3. The work content of each sub-item already includes substrate treatment/cleaning, mortar mixing, transport of concrete and mortar, laying/spreading and curing; these operations must not be itemized separately and re-priced at compilation.
4. Quantities are calculated in m2 by the dimensions shown on the design drawings; deduction/inclusion rules follow the Chapter A.9 notes.
5. These sub-items belong to a consumption standard (quantities separated from prices); when pricing, labor/material/machinery unit prices follow the prices of the compilation period and fee assessment follows Beijing's supporting fee standards.
6. 2021-to-2024 number cross-reference: roof 9-84/9-83/9-85, waterproof concrete 9-89; walls 9-166/9-167; floor 9-209; in one-to-one correspondence with the 2024 numbers (the 2024 edition adds the "A-" prefix). Some old cross-reference material additionally lists 9-87 for roof waterproof concrete; verify against the edition actually in force for the project before application.
7. Missing-item note: within the floor mortar-waterproofing table only A-9-209 (with-waterproofing-agent type) appears; no independent SF polymer waterproof mortar sub-item is seen. If the design uses polymer mortar on floors, handle per the Chapter A.9 notes - do not directly borrow wall sub-item A-9-167.

Applicable Boundaries

• Region: applicable only to building and decoration works in Beijing executed under DB11/T 2382-2024; other provinces/cities follow their current local consumption standards - sub-item numbers and consumptions cannot be transferred directly.
• Edition: this cross-reference corresponds to the 2024 edition (with 2021 numbers given); upon revision of the standard, errata or updates of supporting documents, the currently effective version prevails.
• The consumptions are the standard's set values: unless the standard expressly allows conversion, they must not be adjusted for differences in actual mix proportions, material types or construction methods; prices are adjusted by the compilation period while consumptions do not fluctuate with prices (price adjustment is not quantity adjustment).
• The consumption figures in this card are transcribed from the standard text; verify against the official publication before formal pricing; individual material details (e.g. the concrete supporting-material rows of A-9-89) are subject to the original text.

Further Reading

• DB11/T 2382-2024 "Construction Consumption Standard", Appendix A "Building and Decoration Works", Chapter A.9 "Roofing and Waterproofing Works": Table A.9.2-3 roof rigid waterproofing (A-9-83 to A-9-85, A-9-89); continued Table A.9.3-2 wall coating-film waterproofing, waterproof mortar (A-9-166, A-9-167); Table A.9.4-3 floor mortar waterproofing (A-9-209).
• Further study: read the Chapter A.9 notes (scope of each table, quantity calculation rules, deduction/inclusion provisions); when verifying, compare the corresponding 2021 sub-items (9-84/9-83/9-85/9-89, 9-166/9-167, 9-209); when polymer mortar is missing for floors, handle per the chapter notes or via the supplementary-quota route.
