In a very competitive construction business environment there is a need to measure and manage business performance across a wider spectrum of business success criteria. The Balanced Scorecard (BSC) and Triple Bottom Line (TBL) reporting concepts are emerging as champions in the race for sustainable business success. The construction business organisations are often judged based on their financial performance as well as wider performance. This paper aims at developing a universally accepted tool for assessing contractors' wider business performance in the construction industry. A prototype of web-based business performance measurement system has been developed to help contractors assess their own performance aimed at uplifting their performance. The consultants/clients can also use the tool to measure contractors' performance in a value-based contractor selection. The system was developed based on the research conducted among 63 senior construction professionals and therefore further research with the participation of a large number of managers across different countries and also an upgrade of the system will be required.

Among various methods to build the construction safety, the consecutive improvement by the measuring and evaluating safety management capabilities for the construction participants such as an owner, a contractor, and a supervisor (construction project manager) can be the effective one. Thus, an effective evaluation and grading criteria to provide performance index for the implementation of safety management activities should be necessary. In this regards, the purpose of this study is to verify the adequacy by offering a competency evaluation system for the supervisor's safety capability and by applying the system to some construction sites. The proposed evaluation system was developed on the basis of the principles of safety management & accident prevention, basic elements of safety and health management system, and safety evaluation cases at home and abroad. The trial evaluation showed that the safety management of the construction site is mainly carried out by the contractor and the supervisor's awareness for the safety management is low on the whole. Especially, it is urgent to improve the support system from the supervisor headquarter and to place the dedicated safety management person in the field.

To help a owner selecting proper contractors about the specified contract, the Evaluation and Public Announcing System of the Contractor's Construction Capacity has been introduced since 1997. But, the system has been done violence to its original meaning and purpose as time went on. When annually announcing the Contractor's Construction Capacity, especially, there was frequently a large range of opinion on the issues. On that account, MLTM(Ministry of Land, Transport and Maritime Affairs) has had to make a alteration to improve those and is making efforts for a constructive policy now. The purpose of this paper is to conduct a basis study on the Integrated System after reflecting points to be considered about improvements and the current of the times.

We this study investiged the level of perception such as construction quality-related systems according to the subject of construction work. The results of the recognition moisture survey showed a high response rate in the order of construction companies and supervisors. The result of the system's level of understanding was low at 3.6 points for the orderer and contractor. In addition, in recognition of the effectiveness of the quality management system, the contractor showed a somewhat negative perception than other targets.

"United Nations Convention on Contracts for the International Carriage of Goods Wholly or Partly by Sea" was passed in July 3, 2008. on September 23, 2009 signing ceremony was held in Rotterdam. The system of maritime performing party is a special system in the transport convention, and constitutes an integral part of the Convention. Maritime performing party system is not the first system which brings in the carrier's independent contractor, but it is the most comprehensive and thorough one. It unified the duty of carrier's independent contractor in the maritime segment, and it is also an important progress in the developing process of international maritime legal system. There are some differences between the maritime performing party and China's current related system, i.e, the port maritime performing party and the intermediate performing party are included in the maritime performing party, and they can enjoy the carrier's exception clause and limitation of liability.

In many cases, the construction industry in Korea has a hierarchical structure in which a general contractor in charge of the entire project is subcontracted from the client and entrusts the construction to a specialty contractor in charge of detailed work types. In this structure, the general contractor manages and takes responsibility for the entire construction, but the person directly involved in the construction is an individual specialty contractor, so the quality and safety of the facilities will vary according to their construction and management capabilities. In order to solve quality and safety problems that may arise due to the difference between the person receiving the order for construction and the person who actually constructs it, it is necessary to let the person who receives the order perform the construction directly for projects under a certain amount. The system introduced for this purpose is the direct construction mandatory system. As described above, although this system was introduced to prevent bad construction and risk transfer, it is a system that has various problems due to the characteristics of the domestic construction industry, institutional limitations, and practical problems, so it is necessary to improve it legally and institutionally.

Design-build that a single entity performs whole construction process under singular responsibility is one of the project delivery system comes to take expectation effects of time savings, cost saving, and quality assurance. On the other hand, a current domestic method for selecting a design-build contractor is difficult to reflect the purpose of owner and the project characteristics when owner selects the design-build contractor. The purpose of this research is to suggest a model for deciding evaluation weights in design-build which can reflect the purpose of owner and the project characteristics. This research can help owner to select the best suitable design-build contractor for the project.

The foodservice industry is changing more and more from on-site foodservice management to contract foodservice management. However there are differences according to the level of management and operation of contract foodservice management company (CFMC). The necessity of certification on CFMC is increasing to enable fair discrimination of CFMC among most clients that want to contract with CFMC. This study was performed to identify the foodservice operation evaluation model's criteria items for certifying CFMC. The analysis research methods included literature review, content analysis, individual interview, Delphi technique, and brain storming. First, the following infrastructure items were prepared in the contractor's viewpoint: procurement, transparency of operation, menu development and operation system, nutrition service system, professional employee education, sanitation andsafety management system, customer satisfaction system, facility system, management information system (MIS), business and economics. Second, the evaluation criteria required by the contractor on the client's view point was similar to school foodservice, hospitalfoodservice, and business andindustry foodservice except extraordinary items of field. Third, evaluation criteria and detail categories and items were identified such as financial focus, customer focus, process focus, human focus, and renewal and development by grafting on intellectual capital evaluation methodology for CFMC.

Judging from the past cases, the contractor has frequently suffered losses caused by disapproved requests or reduced payments since it has not known the conditions of the contract or it has filed a claim to the owner without any proper claim system. Therefore, the existing claim process needs to be reformed. In order to reform the claim process, the contractor should consolidate the organizational structure, grant accurate duty assignments to the claims manager, implement regular staff training on how to deal with claims. In addition to this reformation, the contractor needs to improve the management of construction period and process control, and manage related documents thoroughly. Regular meetings are also necessary in claims. This study attempts to prove the effectiveness of the reformed process applied to Project "A", where the owner was responsible for the delayed supply of materials, inaccurate oral instructions, insufficient information on the work, and frequent changes of design. The project was completed in 96 months, which was extended by 34 months from the initial construction period of 62 months. The reformed claim process is expected to be of great help not only to largescale construction works but also to smallscale ones.

Recently, CM at Risk delivery system(CM@R) that could solve the problems of Design Bid Build delivery(DBB) system has been emerging. In the CM@R delivery system, the contractor negotiates for a maximum guaranteed price(GMP) with the client at the design stage, and the contractor carries out the construction within the GMP. In CM @ R, the construction company with expertise in construction participates from the design stage to reflects the construction know-how in the design. On the other hand, the modification design frequently occurs due to the change of the construction cost when negotiating the GMP. In addition, uncertainties are inherent in the GMP calculation because the calculation is based on unfinished drawings and documents. This study proposes a probabilistic GMP estimation method applying MCS to the BIM - based cost prediction model, in order to extract the accurate quantity information when estimating the GMP and to cope with the change of the construction cost inherent in uncertainty.
