Earthwork Optimal Allocation Model of Road Engineering Based on BIM Technology

Earthwork adjustment plays an important role in the construction of the whole project and the impact on the environment. It is important to formulate earthwork allocation scheme on the basis of accurate earthwork calculation. We use professional equipment to collect the electronic initial topographic map, and then use it to calculate the design elevation to generate the electronic design topographic map. The earthwork volume and centre of gravity, the unit transportation cost, and the earthwork allocation scheme with the minimum transportation cost can be finally calculated. This paper presents a model to establish the optimal allocation model of road engineering earthwork based on BIM Technology, and a case is used to verify the model is economical, scientific and reasonable.
