Beijing Prefabricated House Budget

The budget for prefabricated houses in Beijing needs to be comprehensively determined based on the project type, time node, and pricing basis, as detailed below:

I. Budget for Prefabricated Component Projects in Old Residential Area Renovations

If the project involves the seismic reinforcement renovation of prefabricated external panels for multi-story residential buildings in old residential areas, reference can be directly made to the data from the 16th Edition of the Beijing Old Residential Area Comprehensive Renovation Project Cost Index:

• Base Period Unit Cost: 2497 yuan/m² (calculated based on building area). This data is based on seismic reinforcement scenarios, and the material price of prefabricated concrete exterior wall panels has not been adjusted since the first edition.
• Cost Index Adjustment: The cost index was 105.58 in December 2024 and adjusted to 105.31 in June 2025. To calculate the current budget, multiply the base period unit price by the latest cost index (e.g., budget after June 2025 = 2497 × 105.31 ÷ 100 ≈ 2629 yuan/m²).
  Note: This data is only applicable to seismic reinforcement renovation projects and does not include dynamic factors such as design changes and material price fluctuations.

II. Budget Basis for New Prefabricated House Projects

The Standard for Estimated Consumption in Building Construction and Decoration Projects released by Beijing in 2025 specifies that, starting from May 1, 2026, new projects must use the new standard to prepare preliminary design estimates.

• Standard Applicability: Although the new standard does not directly mention special budgets for prefabricated houses, it can serve as a basic basis for pricing building construction projects and requires further refinement based on project design parameters (such as structural form, floor height, and proportion of prefabricated components).
• Time Node Requirements: For new projects initiated before May 2026, reference can be made to similar project cases or the current pricing method can be temporarily used to prepare the budget; for projects initiated after May 2026, the new standard must be followed.

III. Budget Preparation Recommendations

1. Consult Authoritative Institutions: The Beijing Municipal Commission of Housing and Urban-Rural Development is responsible for formulating cost pricing methods but has not publicly released special budget templates or quotas for prefabricated houses. It is recommended to contact the Beijing Construction Engineering Cost Management Station or professional cost consulting institutions for targeted guidance.
2. Dynamic Adjustment Factors: The actual budget needs to consider variables such as market material price fluctuations (e.g., steel and concrete), transportation costs, and construction periods to avoid directly applying static data.
3. Project Type Differentiation: The pricing logic for renovation projects and new construction projects differs significantly. It is necessary to clarify the project attributes before selecting the corresponding basis.
