Abstract:
This paper is based on historical and current activities in the UK but does, where appropriate make reference to developments and parallells elsewhere. It starts with and acknowleges the realisation that we must do something about the depletion of our planet's resources and finishes with a suggestion that by joining the appropriate data together we stand a better chance of doing that. In terms of the construction industry, it starts with a quote from a leading architect of 90 years ago to a world where we are enveloped in data and undergoing an attitude change. The paper proposes that as much data as possible should be freely avaialbe to enrich social life and enterpise collaboration.The role of the built environment and particularly the construction industry that produces it is the main focus of the paper, tracing that industry's relative failings in communications, teamwork and adoption of technology. BIM is the current push and there are high expectations for its capacity to enable the necessary changes and the UK is taking this very seriously, so much that the eyes of the world are now turned towards it and by considered measures it is now generally regarded to be leading as it is highly likely that standards and guidance prepared for the UK market will become internationalised.It will be up to the industry to capitlaise in this situation.

Abstract:
Large amount of information in construction projects is still stored in unstructured documents nowadays. This research focuses on the correlation mechanism between unstructured information with highly structured BIM model, realizing BIM-based retrieval of unstructured information and improving the using efficiency. Title-based and content-based automatic correlation mechanisms are provided, capable of searching correlated entities through selected document, calculating correlation index and ranking and establishing the correlation after users' confirmation. A case-study shows that if entities are well named and expressions in the document match the model, this method is able to recall all the correlated entities, ranking at the top of the list. Correlated document can also be queried dynamically based on BIM model.

Abstract:
BIM and the traditional way of construction have different emphasis and advantages in different stages of design. In every stage of design for solving various problems, a reasonable and comprehensive use of design tools or software will greatly enhance our productivity. In order to integrate theory with practice, according to our actual experience in the projects of Xinzhou Planning Hall, Museum and Archives, we come up with an integrated constructive logic from the perspective of an architect. Through this summary, we hope to bring some enlightenment to the design of this type of project.

Abstract:
United States, Singapore, Japan, Korea and other countries have proposed Building Information Modeling (BIM) application requirements and the establishment of national application of BIM standards in the construction industry. The introduction of BIM technology in China is later and is not yet mature. BIM is currently applied in various industries, particularly in the construction and hydropower industries. All subordinate units of China Railway Corporation have also carried out part of the BIM technology research and application of practical work with several pilot projects. Taking a project engineering as background with the creation of three-dimensional model of the bridge piers rebar, this article introduces Computer-Aided Three-dimensional Interactive Application (CATIA) and advanced knowledge engineering applications in steel bridge BIM Modeling. This application method can quickly create different types of steel piers within the complex structure.Compared with the general three-dimensional modeling methods, it is more efficient, convenient and greatly improves the efficiency of the designer. It also provides important basic information for subsequent simulation in virtual construction, construction technology guidance, information technology and other aspects of construction.

Abstract:
In this article, two BIM applications of the United States were selected to present how to use BIM to reduce building energy consumption and to realize the "Digital Factory". In the first case, how to use BIM techniques to simulate building energy consumption was presented. A series of energy efficiency measures have been proposed and also quantified. The results from BIM energy simulation show that total energy cost will be reduced by at least 20% if appropriate measures are taken. The second case presented how to use BIM to realize the digital factory. This project was for ongoing operations and maintenance and the overall design process should allow access to facility-related data from many sources, including the existing documents, models, and drawings. Owner group, WFG facility management, knew well how they pre-set for this project and played an appropriate supporting role to provide all fundamental data and standards for efficient workflow.

Abstract:
As the BIM technology is under a rapidly developing stage, it has been regarded as a crucial tool for the whole building stages, namely the design and construction. This article investigated the application of Lumion in BIM technology, and thus the whole process data could be shared. Exporting the Revit model into Lumion could improve the building model quality and minimize the working time and labor power, which could support the later stages better.

Abstract:
For most free forms, we usually start from the logical structure of mathematics. However, it is difficult to control the building form from the overall perspective, and as a result, we often have a deviation from the overall control of the design trend. In order to solve this design problem, according to the practical experience of TIENS University Sports Center project, we present a set of digital construction and logic optimization experience. We hope to bring some useful inspiration to the design of such projects.

Abstract:
As a realization tool of BIM, Revit is applied widely. As an introduced foreign software, Revit needs to abide by Chinese norms and build proper members in practical application. When using Revit to build models, it utilizes its own elements or tools to erect complicated models. This method can avoid too much outside families loading, which slows down the running velocity of software. This paper contains three parts, covering wall members, roof\floor\ceiling members and modified tools of construction drawings. This method is convenient for listing, and it also enhances velocity of building models, so it can be put into use in practice.

Abstract:
Taking Changfeng station of Wuhan Metro Line Ⅶ as an example, this article shows that the process of ultra-deep excavation have many risks by theoretical analysis of Fault Tree, such as leaking joints, longitudinal instability, pit deformation, gushing water and sand, surface subsidence around the base hang basement uplift and so on. The article analyses the monitoring data during the excavation of Changfeng station in May including the inclinometer of underground continuous wall, soil subsidence, post settlement and so on. The analysis results show that large underground continuous wall inclinometer, upright settlement, underground continuous wall seepage etc. are the signs of large pit deformation, as well as common risks of ultra-deep excavation process. So we should erect steel braces timely, grading excavation, strengthen monitoring and provide rainfall timely to control them. By timely warning and taking appropriate security measures, the excavation pit risk of Changfeng station was controlled effectively, and the main structure of Changfeng station was completed successful. The success of early warning and control of Changfeng station excavation risks can provide recommendations for the Wuhan soft soil excavation.

Abstract:
According to the "green action plan", China should complete new green building of 1 billion square meters during "the twelfth five-year plan" period. By the end of 2015, 20% of new buildings in cities and towns will fulfill the requirements of green building standards. However, for the rapid developing green building in our country, we should analyse and solve the problems existing in the operation management as soon as possible. Green operation concept is presented in this paper on the basis of analysis of the green building of during the operational management, and suggestions are given to improve the level of green building operating measures, finally summarizes the effective means of operation management and its important meaning to sustainable development. Green operation caused by the imperfect high running cost and national incentives tend to damage the enthusiasm of developers and property management team, therefore, effective means of operation management is the key to the implementation of green building.
