Constructional engineering bidding document generating method

The invention provides a constructional engineering bidding document generating method. The constructional engineering bidding document generating method comprises establishing a civil engineering 3D model, a steel bar 3D model and a water, warm supply and electricity 3D model; calculating the budget quota, adjusting the price difference, and leading out an engineering price-calculating table; calculating work days needed by each operation in dependence on the led-out engineering quantity and the labor quota, and compiling a progress plan and a resource supply plan; integrating the 3D models, the progress plan and the resource supply plan which are needed by the constructional engineering; adjusting the progress plan and the resource supply plan, optimizing the progress plan, finally completing engineering simulation construction, recording and preserving the engineering simulation construction process by means of screen recording software, generating a video file used for constructional engineering bidding,
