It is suitable for new prefabricated building engineering projects, and can be used for reference for expansion and reconstruction projects.
This index is the reference for the preparation of investment estimation, multi scheme comparison and optimization design in the early stage of prefabricated construction project.
The investment estimation index of prefabricated building engineering (Exposure Draft) is prepared based on the evaluation standard for prefabricated buildings (GB / t51129-2017) and the current relevant engineering and construction technical standards, combined with the representative prefabricated engineering data in China in recent years.
It is the main economic index for evaluating investment feasibility and analyzing investment benefit in the project decision-making stage..
