BIM-based highway engineering rapid cost method

Abstract

The invention discloses a BIM (Building Information Modeling)-based highway engineering rapid manufacturing cost method. The method is based on a BIM unified coding rule. The method comprises the following steps: establishing a relatively comprehensive highway construction process flow library CTPD (Construction Technology Process Database) and SPPD (Set the Prince of Process Database), and enabling a BIM component to be endowed with the process attribute and the component price attribute corresponding to the BIM component through the CTPD and the process component price library (SPPD), so therapid and accurate manufacturing cost is realized, and the manufacturing cost speed and efficiency are improved; after CTPD and SPPD are established, automatically identifying and artificially establishing a basic standardized model based on the BIM platform; based on geometrical information of the model, realizing the calculation of sub-project quantities by adding non-geometrical information and setting an algorithm conforming to project quantity calculation rules; selecting a procedure combination of the subentry engineering construction process through the CTPD intelligent identification;based on the selected process combination, reading the group price block in the SPPD to realize conversion from model thinking to data thinking.

Description

technical field [0001] The invention relates to the field of highway engineering cost methods, in particular to a CTPD-SPPD rapid cost method based on a BIM platform. Background technique [0002] The pricing method often used in highway projects is still the fixed pricing method. However, as my country's planned economy integrates with the market economy, the mandatory quotas that have served the planned economy period for a long time cannot meet the needs of the highway industry. my country's highway industry should actively integrate with foreign countries, and explore the application prospects and feasibility of the bill of quantities valuation model in my country. [0003] Quantitative pricing is to calculate the engineering quantity of each sub-item according to the calculation rules of the fixed engineering quantity implemented, and calculate the cost of labor, materials and machines according to the unit valuation table and information guidance price issued by the co...

Problems solved by technology

At present, the domestic construction field has achieved good development in BIM, but the application of BIM technology in road construction projects is relatively insufficient

The engineering cost BIM software that conforms to the domestic pricing rules is still in the initial testing stage, and the cost management (5D) function of the BIM collaborative platform is not yet perfect
