IFC implementation in lifecycle costing

Life Cycle Costing (LCC) is always a major concern in the Architecture, Engineering and Construction (AEC) industry. This paper presents the implementation of Building Information Modeling (BIM) technology in the development of a lifecycle cost-estimating tool. The IFC (Industry Foundation Classes) model as an interoperable building information model has been adopted as the central data repository to deliver the integrated information of building designs from CAD design systems into the lifecycle-costing database. In this paper, the conceptions and relevant factors, which could affect the LCC estimation, have been introduced. The problems of current LCC applications have been identified as the lack of LCC data and the complexity of LCC exercises. The software application of IFC models and relevant auxiliary are depicted as a solution of the problem identified. The lifecycle costing tool is a part of the nD Modeling tool and as such is based on its integrated interface prototype toolkit and is able to holistically present an IFC model into a 3D virtual reality view, a tree-view and a list of element properties. The functions and some technical points are also detailed in the paper. Through the research, it demonstrates the potential and possibility of implementing BIM methods and techniques, particularly IFCs to enhance the computer applications in the processes of building construction and facility management.

Interoperable Process： Efficient Systems in New Constructive and Product Performances

In the construction sector, which is one of the major goals of the new economy, the company is aiming at a new constructive practice and upgrading of the built, using ICT （information and communications technology） technologies. So the focus is on new operating and organizational models of sustainable building processes in the architecture, engineering and construction sectors, which are based on three-dimensional models of digital technology BIM （building information modeling）. It is intended as a human activity that improves building workflows and, through software and IFACs （industry foundation classes）, manages flexibility, coordinates and optimizes operational choices on time, economic, and environmental sustainability parameters. The goal is a new interoperable building process that involves designers, contractors and businesses from programming to lifecycle building and maintenance through the integrated project delivery of the building. Dynamic architectures, interactive with efficient technological and constructive systems, are integrated with innovative products of complex nature and bi-directional performance, engineered, with energy storage and renewable resources. The methodologies are based, above all, on the adoption of BIM technologies with the digital project manager and the use of robotic technological tools. Digitization is applied for the design and construction of architectural and infrastructure artifacts, in interaction with intelligent, adaptive, nanotechnical and user-friendly materials and climate. The results are aimed at efficient buildings with user comfort and safety, accuracy, and risk monitoring with remote monitoring, highlighting VDC （visual design construction） in CID （computational intelligent design）.

Ethics and Integrity in Building Employee＇s Perceptions

Malaysia has long been involved in the initiative of becoming a high income country by the year 2020. In this essence, fighting and eliminating any means of corruption in the public and private companies have been one of the key challenges in the long run. The globalization of businesses has somehow led to an increase in the number of unethical conduct and hazardous corruption. In the urge to enliven ethics and integrity in a company and among employees, the whole business processes and stakeholders should position code of ethics and integrity at its highest standard. However, can ethics and integrity really increase the company＇s reputation, strengthening its business operations and sustainability, and deliver trust amongst employees and employers？ The objective of this study is to analyze the perceptions of employees on issues pertaining ethics and integrity. The study has been conducted in one of the giant telecommunication companies in Malaysia where a sample of 7,056 employees were the participants involved in the survey. The study has used questionnaires to collect data. The data have then been analysed using the SPSS data analysis software. The findings explained that employees view the company as an ethical place to work where the finance department is deemed to have the highest level of integrity. While in matters of corruption risk areas, there are still practices of bribery. It is also founded that a majority of respondents about 93% agree that the company＇s initiatives are effective in building business integrity and that the level of business ethics and integrity has improved over the last two years. Running a business with ethics and integrity while selecting the fight business partners will create a corporation of ethics, integrity, and anti-corruption.

Analysis and results to the status of BIM technology application in China

Information age and the rapid development of information technology has brought the infinite creativity and possibility for all works in modem society. If CAD technology is first innovation of information technology in construction industry, then the emergence of the BIM technology shall fully deserved to be treated as a second innovation in construction industry. As a new technology which have been introduced to China in recent years, BIM technology already had its major application in foreigner countries .This paper focuses on the current status of BIM technology application in our country, especially on some small and medium enterprises using the traditional BIM technology to handle the project which have complex usage,creative deign and cost limitation. Firstly,we take a deep analysis on the initial application situation. Then we go through the practical application and analyse what benefit can be given to a project from BIM technology. Finally, analyse the problems and solutions in BIM application with consideration of Chinese building engineering development. Only after a careful analysis, a deep understanding of BIM, we can fully understand this new technology and make BIM to give its value to construction project.

BIM Implementation--A Bibliographic Study of the Benefits and Costs Involved

The construction sector has always been constantly changing, becoming increasingly aggressive, requiring new strategies to adapt to international and national scenarios. In the development of a project, there are many constraints, which often end up in problems such as waste materials, generating waste affecting the environment and also resulting in high costs oftbe work that could be avoided. Then came the concept of BIM （building information modeling） defined by a digital model consists of a database, allowing the development of projects with various professionals working in an integrated manner, being able to support all aspects of the life cycle of the project. Therefore, from the research information on the implementation of BIM methodology, it was possible to propose new ways of thinking and designing buildings, contributing to the completion of research in the management of projects and sustainability areas relevant to the development of engineering.

Research on the credit classification of practicing qualification personnel in construction market based on self-organizing neural network

Combining with the characters of the practicing qualification personnel in construction market,evaluation method based on the self-organizing neural network is brought out to analyze the credit classification of the practicing qualification personnel. And the impact factors on the credit classification of the practicing qualification personnel,such as the number of neurons,the training steps,the dimension of neurons and the field of winning neurons are studied. Then a self-organizing competitive neural network is built. At last,a case study is conducted by taking practicing qualification personnel as an example. The research result reveals that the method can efficiently evaluate the credit of the practicing qualification personnel;thus,it could provide scientific advice to the construction enterprise to prevent relevant discreditable behaviors of some practicing qualification personnel.

A Quarter Century of Work to Revolutionize Architecture, Engineering and Construction Enterprise Information Systems

More than two decades ago, object-oriented representation of AEC （architecture engineering and construction） projects started to offer the promise of seamless communication of semantic data models between computer-based systems used from the design stage to the operation of the facilities. BIM （building information modelling） emerged and appeared as a means to store all relevant data generated during the life-cycle of the facilities. But this upstream view of the built environment, arising from the design and construction stages, extended to the downstream operations where building and industrial facilities appeared more and more as huge dynamic data producers and concentrators while being operated. This created new challenges leading to what is referred to as ISCs （intelligent and smart constructions）. The current state of the art is that final constructions still contain various and increasingly versatile control and service systems, which are hardly standardised, and not interconnected among themselves. Monitoring, maintenance and services are done by specialised companies, each responsible of different systems, which are relying on customised software and techniques to meet specific user needs and are based on monolithic applications that require manual configuration for specific uses, maintenance and support. We demonstrate in this paper that the early promises of integration across the actors and along the life-time of facilities have gone a long way but will only be delivered through enhanced standardisation of computerized models, representations, services and operations still not yet fully accomplished 25 years after work started.

An Overview of the Feasibility of Achieving Level 2 Building Information Modeling by 2016 in the UK

The aim of this study is to investigate the current status and feasibility of achieving Level 2 BIM （building information modeling） usage that is to be made mandatory by the UK govermnent on its projects by the year 2016. This study assesses the level at which organizational and practitioner knowledge of BIM is currently positioned. The UK government, being the largest public stakeholder client, has realized the benefits and advantages of BIM when used in procuring projects across their lifecycle in the built environment. A critical review of the BIM literature was carried out and the evidence base was created in relation to government targets for 2016. At the current stage, Level 2 BIM adoption is achievable by 2016 for large construction firms but not for SMEs （small medium enterprise）. Also, from evidence in this study, the technology needs to be properly tailored to meet SME variables if Level 2 status is to be achieved for the entire industry.
