The construction of a facility is an act whereby infrastructure such as roads and railways and other facilities such as housing and office spaces are constructed, and due to the characteristics of the relevant industry where such construction is carried out in a custom order method, it requires a long period of time mostly. While the construction is carried out over a long period of time, fluctuations in the price of raw materials required for the construction occur. Therefore, the cost of the construction also fluctuates inevitably. The fluctuation of the construction cost meshes closely with the profit of a constructor and the efficiency of government spending. Therefore, it is necessary to maintain the construction cost at a reasonable level by adjusting the construction cost rationally in order to secure the required construction quality and spend the budget efficiently. The buffer system for solving such problem is the contract amount adjustment system by fluctuations in prices (Escalation/De-Escalation). In this study, the method combining the escalation method based on the item adjustment method was suggested for an efficient contract amount adjustment method. In addition, it is proposed that there be an investigation and codification of matters not applied to government acts and regulations on contracts related to the adjustment of fluctuations in prices legally.

Currently, TK(Turn-key) projects have been implemented, the projects on TK basis still have shown several problems rather than its own merits as a bidding method. Increasing the number of claims being occurred during construction process of the projects is reality because of unclear notice of tender documents and conditions of the contract, design review system, and decision process of the qualified bidder. To establish desirable TK projects in domestic market, not only should resonable alternatives for carrying out design review system and selecting the bid winner be set up, but also proper standards for reforming irrational system of contract, bid, and notice of tender related to TK projects. This study is intended to reduce the number of claims and implement efficient projects of apartment construction on TK basis by identifying potential problems through analysis of claim examples of TK projects which have difficulties of revising contract agreement such as drawings and suggesting improvement methods for contract conditions and notice of tender docuements.

The number of claims and disputes among project participants has been steadily increasing last a few years and it creates numerous conflicts and problems in the domestic construction industry. One of the root causes of claims and disputes can be explained by the fact that project objectives of participants are offer different and not aligned. This research is considered as a pre-study of developing a strategy to mitigate conflicts such as claims and disputes in the domestic construction industry by utilizing Alternative Dispute Resolution (ADR) techniques. This research focused on improving standard contrast documents to establish a systematic dispute resolution process which emphasize the ADR method. To do so, several well-recognized contract documents developed by FIDIC, AIA, ECC were throughly investigated and analyzed using a benchmarking process. Result of the research propose needs of improving the domestic construction document's some clauses and the details will be further Investigated through surveys and expert's opinions.

Recently many construction claims related to the ommission and discrepancy of design document are alleged since 1998 and various dispute resolution methods are appeared. But many contractors alleged claims are not satisfied with the result because of not sufficiently reflecting construction practice. The purpose of this study is to analyze the liability of contract privity from the view point of the contract related law and to analyze the claims and claim factor, and to suggest construction contract practice in the public project. The construction claims related to the design document may be minimized, through (1) the accumulation and retrieval of standard forms by owners' type, (2) the usage of specified specification considering project characteristics, (3) the materialization of detail subsurface design and various contract method in heavy engineering construction.

CM at Risk has been introduced in Korea to keep up with the global standards of construction management and provide a higher quality of cm service in line with a rapid change of the construction industry recently. However, it is widely considered that more time would required to settle down the system due to a lack of understanding towards CM at Risk, shortage of reliability and low capability to manage and undertake CM at Risk. Therefore, this research is analyzed problems of contract types, open book policies, and contract conditions of 33 numbers of projects undertaken by a bespoke domestic construction management firm in this research. Moreover, this research is suggested a method to establish an open book policy of CM at Risk aiming a better customers satisfaction through staff training, simplifying and improving a payment system, and a way to settle down an open book policy by improving a performance management system on site. It's expected that this research will contribute to a more competitive system with more dominating the market and a differentiation of the service so as clients to rely more on the CM at Risk.

The business market of architecture has got a system that controls a deposit according to the price function. This system is written on a law of contract about countries. So the main body of construction has to make a reasonable contract. This study is written about a rate of numerical index on controling a deposit. We tried to fine problems and solutions of labor expenses, instrument costs and material costs which is so big and changable on the construction market Labor expenses are expressed according to the rate of construction scale between direct and indirect cost that applies ability of works. Instrument costs are expressed according to an output method of a unit price annually and a weight allowance of local instrument conditions and use frequence. The last material costs expressed according to a local weight allowance make a decision of the material cost index. They applies locally relative index more than absolute one on what uses the price rate of producers and importations. This solutions are not enough to apply to the real market, so it needs to exam and to be on the market after a feasibility study.

Although claims and disputes may be never avoided in construction industry, until 1998, there are no systematic claims in the public sector in Korea. But, because of IMF, Contractors have been recognized that cost management is essential factor and contractual right can be demanded against the Public Orderer. Many affirmative effect such as, appearance of new professional service, prevention of lower quality construction, restrain of unnecessary budget expenditure, arrangement of duplicated or triplicated liability and revision of unnecessary administrative control may be anticipated through alleging claims, but in site representative manager and construction company may have ambiguous fear, somebody tried to allege claims. Therefore, to activate systematic construction claims, 32 public construction project claims alleged by contractors from 1998 to 2001 were analyzed, inactivated reasons of claims were examined and contractor's action plan to allege claims was suggested in this paper.

This study analyzed both the legal system regarding fair trade and the types of unfair trade in the construction industry. Then, it derived the factors with which to evaluate the level of fairness. These factors were classified by each type of participant in the construction industry, such as general contractors and subcontractors, and each construction stage, such as bidding, contracting, and construction. The perceived fairness level of factors was analyzed using a survey of 238 employees of general contractors and subcontractors. Next, the study developed a fairness index for the construction industry. The index showed that subcontractors perceived the level of fairness more negatively than general contractors, but both perceived the construction stage of the industry as having the lowest level of fairness. General contractors perceived the bidding and contracting stages as having the highest fairness levels, and subcontractors perceived the contracting stage as having the highest level of fairness. The developed fairness index identified the evaluation factors that need improvement and the fairness level perceived by each type of participant at each stage of construction. The results of this study can contribute to establishing measures that improve the level of fairness in the construction industry.
