Construction management is in the construction process one item is very important and the very complex work, its goal is needs to guarantee that the project according to design requirements’ quality, the plan stipulation’s progress and is lower than the planning budget or the contract contracting cost cost, the security, completes the construction work smoothly, i.e. must make the construction work to carry on quickly, is also good, saves, is also safe. The civil engineering, the bridge building, specially is been specially big natural condition’s influence, its production characteristic is the product position is fixed motionless, but makes the labor force which, the machines and tools, the material the product needs is mobile; The product production cycle is long, moreover the most products are disposable; The production program and the technique of production because of special details’ difference, need unceasingly the adjustment and the change. Therefore construction management work wants the factory production management work complex to be much more difficult than, this requests the personnel who is engaged in the construction to give the enough value, must momentarily keep abreast of the actual situation which and the existence question in the construction the project progresses, uses the science the management, carries on the practical effective work, can serve the anticipated purpose. Develops the traditional use writing, the form, the diagrammatic form mode of administration unceasingly along with the computer technology, already could not adapt the current large-scale bridge building management construction, the virtual reality technology’s appearance has provided the powerful technical basis for the change tradition’s construction management way, selects the 4D method to carry on the management to the architectural engineering the way to arise at the historic moment.In the current computer technology high speed development’s time, realizes the bridge construction management visualization using the computer is in project management important means that but construction schedule management used the dynamic form to manifest, has overcome the traditional two-dimensional blueprint as well as the form not vivid image shortcoming, already became the later project construction inevitable trend. The progress schedule uses the VR platform to manifest directly, the full-scale mockup has computer-aided design software CAD and 3DSMAX completes.
