Landscape visualization is often used in project bidding，communication，presentation，promotion，etc.，and it is an essential part of the design process. The mobile application has been the most convenient and speedy way of communication in our life. It will have a significant impact when applying the landscape visualization method on the mobile applications for the design，construction，operation，and maintenance of engineering projects. Based on the Unreal Engine4 development platform and taking a BIM design project of a wharf as an example，we realize the landscape visualization application on android devices. A set of visualization processes and methods for the BIM design are summarized，which can be used in landscape demonstration，smart guide，emergency drill，and equipment maintenance of the project.
