Ased on the analysis that the application of the subdivision surfaces modeling technology is feasible in the three-dimensional geological modeling, and for the problem of data coherence between the various public faces in the multi-body modeling process of the three-dimensional geological modeling, the border stitching algorithm is proposed based on an improved butterfly subdivision strategy, and makes the different subdivision degrees of model smoothing out. The technology of view depend subdivision surface is introduced into three-dimensional geological surface model construction, and to help the establishment of three-dimensional geological structure of the LOD model. Finally, the feasibility and effectiveness of the method is verified by taking a certain city area as the studying area and carrying out experiment of the application of the method presented by this paper.

The variants of the division of the life cycle of a construction object at the stages adopted in the territory of the Russian Federation, as well as in other countries are considered. Particular attention is paid to the exemplary work plan – "RIBA plan of work", used in England. A feature of this document is its applicability in the information modeling of construction projects (Building information Modeling – BIM). The article presents a structural and logical scheme of the life cycle of a building object and a list of works that are performed using information modeling technology at various stages of the life cycle of the building. The place of information models in the process of determining the service life of the building is shown. On the basis of the considered sources of information, promising directions for the development of the life cycle management system of the construction object (Life Cycle Management) and the development of the regulatory framework in order to improve the use of information modeling in construction are given.
