GB/T 50500—2024 Cost composition of the all-in unit rate (labour + materials + plant and small tools cost + management fee + profit + risk cost, excluding VAT)

Topic Positioning

This card explains the composition scope of the 'all-in unit rate' in GB/T 50500—2024, the China national pricing standard for BOQ, used — during BOQ-based pricing, preparation of tenders (priced offers), and settlement verification — to determine which costs are included in the all-in unit rate and which are listed separately under VAT items.

Core Conclusions

The all-in unit rate = labour cost + material cost + plant and small tools cost + management fee + profit + risk cost within the agreed or reasonable range; it is a fully inclusive price excluding VAT (Clause 2.0.9 terminology). Under Clause 3.1.6, the all-in unit rate and the total price of each billed (BOQ) item shall be a fully inclusive price excluding VAT; taxes and duties (VAT under the current standard) are listed separately under the VAT BOQ item and are not included in the all-in unit rate. The all-in unit rate must additionally cover: costs of meeting national and industry technical standards and specifications, costs of errors and omissions in the BOQ under lump-sum contracts, costs of tasks necessary for completion and delivery plus indispensable auxiliary work, costs arising from construction sequencing, construction conditions, environment and climate, and risk costs within the scope and risk band (no-adjustment tolerance, e.g. ±5%) specified in Section 3.3 (Clause 3.2.2). Compared with GB 50500—2013, the cost item 'overheads (company and site)' was renamed 'management fee', and the price is explicitly a fully inclusive price excluding VAT.

Applicable Boundaries

Applies to BOQ-based pricing activities in the tendering/awarding and implementation stages of construction works; it addresses only the 'all-in unit rate of billed (BOQ) items' scope — VAT is a price-exclusive tax, listed separately. The 2013 edition's 'overheads (company and site)' and the 2024 edition's 'management fee' both fall within the management fee composition. The VAT-exclusive basis does not apply to projects with VAT-inclusive lump-sum price agreements.
