Pricing rules for fan-coil-unit installation: the installation sub-item measured per "unit" by installation type, the unit body listed separately as an unpriced main material, and supports distinguished between supplied with the equipment (included) and fabricated on site (applying equipment-support fabrication and installation banded by each support's weight) - per Beijing DB11/T 2382-2024 Section 6.7, with a railway TB/T 10831-2024 quota comparison

Topic Positioning

Pricing (quota application) rules for fan-coil-unit installation in ventilation and air-conditioning works: how the installation sub-item is set, how the equipment body as main material is listed separately, how supports are applied according to the case, and a cross-system quota comparison. The primary basis is Section 6.7 "ventilation and air-conditioning installation works" of the Beijing local standard DB11/T 2382-2024 "Construction Consumption Standard", with a comparison of like sub-items from the railway budget quota TB/T 10831-2024 "Railway Engineering Budget Quota, Volume 10 Building Works".

Core Conclusions

1. Installation sub-item

• Apply the corresponding "ventilation and air-conditioning works - fan coil installation" item. Clause 6.7.11: "Fan coil installation quantities shall be classified by installation type and calculated by the design quantities." That is, first determine the installation type from the drawings (exposed/concealed etc.), apply the corresponding item, measured per "unit".
• Clause 6.7.7: "Indoor-unit installation of multi-split air-conditioning systems and induction-air-terminal installation shall be executed under the fan-coil installation items according to the installation type." - multi-split indoor units and induction terminals have no separate items and are priced under the fan-coil items.
• The body text of the standard gives only the quantity rules; the specific sub-item numbers are to be retrieved under "fan coil installation" in the official edition of the consumption standard or the pricing software.

2. Equipment body (main material) The FCU body is an unpriced material listed and priced separately at compilation-period prices (price information / purchase price). Clause 6.7.3: "The consumptions of the main materials of ventilation and air-conditioning works - ducts, valves, outlets etc. - shall be shown in the form of added brackets and shall not serve as the base of the other-materials fee." (Bracketed materials are excluded from the other-materials fee base.)

3. Supports (judge the supply mode first - two routes)

1. Supplied with the equipment (finished hangers / vibration-isolating hangers, bottom underlay) -> no additional quota. Clause 6.7.5: "The construction consumptions of ventilation and air-conditioning equipment installation shall include the installation of the equipment supports or bottom underlay supplied with the equipment."
2. Fabricated on site -> apply the "equipment-support fabrication and installation" items. Clause 6.7.24: "Equipment-support fabrication and installation quantities shall be classified by the weight of each support and calculated by the design mass; fan hanger fabrication and installation quantities shall be classified by fan model and calculated by the design quantities; equipment bottom-underlay installation quantities shall be classified by material and calculated by the design mass."
3. Where the design includes seismic supports and hangers, itemize separately. Clause 6.7.37: "Seismic-support installation quantities shall be classified by type and calculated by the design quantities."

4. Cross-system comparison (TB/T 10831-2024 Volume 10)

• Fan coil installation: FY-2670 exposed RMB 69.13/unit (labor 65.57, materials 3.56, machinery 0); FY-2671 concealed RMB 172.46/unit (labor 80.56, materials 74.2, machinery 17.7). Work content: unpacking, checking accessories, base and bolt holes, hoisting, leveling and aligning, adding pads, bolting, fixing, fitting ladders.
• Equipment-support fabrication and installation: FY-2675 (CG327 <= 50 kg) RMB 907.54/100 kg (labor 446.81, materials 396.2, machinery 64.53); FY-2676 (CG327 > 50 kg) RMB 624.47/100 kg (labor 210.73, materials 378.34, machinery 35.4). Work content: lofting, cutting, straightening, drilling, welding, forming, positioning, installing, bolting, fixing, hole drilling, embedding supports.

Applicable Boundaries

• DB11/T 2382-2024 is a Beijing local standard; the above pricing rules apply to construction projects within the Beijing administrative region; other provinces/cities execute the corresponding chapters of their local consumption/budget quotas - the clause structure is similar but the sub-item numbers differ.
• The railway quota figures (FY-26xx base prices) belong to the TB/T 10831-2024 system, for cross-system reference only - not directly usable for pricing Beijing or other local projects.
• Boundary-check essentials: supports supplied with the equipment must not be re-applied under support fabrication/installation; site-fabricated supports select the band by each support's weight, noting the quota unit (e.g. 100 kg); fan hangers, bottom underlay and seismic supports have different measurement bases (count vs mass).
• The specific sub-item numbers of fan-coil installation are subject to the official edition of the standard / pricing software; this card does not replace verification against the official edition.

Further Reading

• DB11/T 2382-2024 "Construction Consumption Standard", Section 6.7 "ventilation and air-conditioning installation works", key clauses: 6.7.3 (bracketed materials and fee base), 6.7.5 (supports supplied with equipment), 6.7.7 (multi-split indoor units / induction terminals), 6.7.11 (fan-coil quantities), 6.7.24 (equipment supports / fan hangers / bottom underlay), 6.7.37 (seismic supports).
• TB/T 10831-2024 "Railway Engineering Budget Quota, Volume 10 Building Works", Chapter 3 building-equipment works, Section 3 ventilation and air-conditioning: (5) fan coil installation (FY-2670, FY-2671), (8) equipment-support fabrication and installation (FY-2675, FY-2676).
• Duplicate-pricing check direction: after obtaining the work content of the fan-coil installation sub-item, compare it item by item with that of "equipment-support fabrication and installation" to confirm hangers / vibration isolators / underlay are not priced on both sides.
