Abstract:
To the subjects in the project department of economic responsibility for the "joint venture project management", data acquiring becomes the key step for enterprise management in cost management informationization. According practical conditions in Zhejiang enterprises, we present an informationization model for cost management:"separate price from quantity for principle, project progressing for main line, part and time for check node". During building informationization, it also combine with practical conditions of enterprise to create key control system for project, construct enterprise system and find the balance between premium quality series informatization assesssment and self-management requirement of enterprise. While developing cost manage informationization module to make it to be an valid and pragmatic one, it is absolutely necessory to consider the practise operation situation of project department.

Abstract:
The idea of BIM is correct and the technology of BIM is applicable, but the software of BIM is not perfect. Based on the features of water treatment projects, two collaboration patterns provided by REVIT will be discussed in this paper. The first one is to use LINK pattern, another one is to use work set pattern. However, the effects of using those patterns are not ideal. According to the advantages and disadvantages of two patterns, a new way, which combines two patterns, has made a little progress, but it still cannot meet the design requirements. The main problem, which leads to that result, is how to divide the boundary conditions of two patterns. After some procedures are tried, the solution has been determined. The work set is established according to architecture, structure and MEP, and LINK pattern is going to be applied to the former building, site and etc.

Abstract:
Essential of BIM is management and interoperability of building information. This article demonstrated the principle of building information management. In managing information, principle is"by domain"; in sharing information, principle is"by practice". Information must be classified by domains, and each domain manage its information by itself. Common properties of building object are basis of BIM, special information used by domains are expansion. We not only emphasize consistency of information expression, but also pay attention to practicality of information using.This article illustrated the standpoint by application of BIM in PKPM software.

Abstract:
Building Information Modeling (BIM) has gained rapid acceptance in the building industry in recent years in Hong Kong; both the government and the industry practitioners realize this irreversible trend of changing gradually from traditional 2D representation of building product and fragmented contributions from the stakeholders to 3D product model and streamlined lifecycle management in the near future. This research presents an overview on the implementation of BIM, its current state of practice in Hong Kong. While the primary intention is to introduce the BIM-related works and preliminary benefits; the authors also intend to identify the obstacles and challenges faced by industry practitioners of such implementation in Hong Kong from social and technological contexts. A case study is used to illustrate the benefits of BIM implementation by a large contractor, as well as the technical limitations and difficulties steering toward the "ideal scenario" envisaged by using BIM technologies.

Abstract:
In this paper, the current numerical simulation method for RC shallow beams is summarized. Using different FE model and constitutive model, two RC beams from experiment conducted and documented by Bresler et. are analyzed. By comparing analysis and experiment results, the best combination of FE model and constitutive model used for numerical simulation is pointed out; explanation for differences between analysis and experiment results has been given out. Furthermore, the study shows that ultimate bearing capacity of beams should not be simply determined as the imposed load when the solution is not converged but be related to strain of concrete in compression region and stress of reinforcement in thensile region. At last, the sensitivity of some parameters is studied by single factor method. All the conclusions from this paper will promote the standardization of numerical simulation of RC beams.
