The purpose of this study is to examine the problems of the regulations regarding the modification of subcontact price. It also suggests several measures to improve the regulations related to the subcontact price adjustment which help to reduce unnecessary claims and commercial disputes. The literature research, structure and context analysis on the subcontract regulation and survey are adopted as basic research methods. The primary findings of this study are summarized as the following: (1) A provision outlining necessary procedures that an owner and a contractor should notify a subcontract or the adjustment of contact price needs to be made. (2) A provision allowing procedures that subcontactor could make the alteration of subcontract agreement and adjustment of subcontact price needs to be made. (3) The terminology like a unit cost and the rate of contact price needs to be clearly defined in order to improve the criterions of the subcontact price adjustment. (4) The criterions and additional expenses that the contractors ate responsible far need to be defined.

In case of long time progressive construction work, we need contract sum adjustment due to escalation for a period of works and the process of applying, consistent and obvious criterion is required. In this study, it were attempted to figure out problem and study this rational improvement by giving examples based on core activities of escalation adjustment. Based on literature study and legal system analysis, we classified processes of contract sum adjustment for escalation and defined 20 core activities for each process. From this measured variable, we carried out case study by giving 37 examples of escalation. As a result of case study, problems of each process was found and we suggested rational improvement. As this study, providers will be able to waste budget and the other will be given smooth escalation adjustment.

The loss of potential opportunity profit which is consisting in the partial markups of the corporation would taking placed in related with the time-delay deeply, has customarily disregarded in contract adjustment under the principles of denial of cost accounting method, declined conjecture in the point of benefits and protection of the law in scope of compensation and the restricted conditions of constant contract. It is being resulted from that the policies of the general principles of accounting standards which is subjected to ask an objective data and evidence, and the denial system as a debt derived from imperfect legal theory applied by current law. Therefore, it is necessitated to find if any irrationality in the positive system is and further to draw an improved reasonable measures to adopt by review of constant system preparing tile reasonableness with the method of suitable quantification devices provided that any time-delay is induced by the party.

This study analyze the factors affecting the number of bidders in public contracts by collecting contract data such as purchase of goods, service and facility construction through KONEPS among various forms of public contracts. The reason why the number of bidders is important in public contracts is that it can be a minimum criterion for judging whether to enter into a rational contract through fair competition and is closely related to the budget reduction of the ordering organization or the profitability of the bidders. The purpose of this study is to analyze the factors that determine the participation of bidders in public contracts and to present the problems and policy implications of bidders' participation in public contracts. This research distinguishes the existing sampling based research by analyzing and analyzing many contracts such as purchasing, service and facility construction of 4.35 million items in which 50,000 public institutions have been placed as national markets and 300,000 individual companies and corporations participated. As a research model, the number of announcement days, budget amount, contract method and winning bid is used as independent variables and the number of bidders is used as a dependent variable. Big data and multidimensional analysis techniques are used for survey analysis. The conclusions are as follows: First, the larger the budget amount of public works projects, the smaller the number of participants. Second, in the contract method, restricted competition has more participants than general competition. Third, the duration of bidding notice did not significantly affect the number of bidders. Fourth, in the winning bid method, the qualification examination bidding system has more bidders than the lowest bidding system.

행정자치부가 지난 9월 20일 지방계약법 시행령 개정안을 공포하고 이날부터 시행에 들어갔다. 개정된 시행령은 당초 행자부가 분리발주를 억제하기 위하여 지방계약법 제77조를 개정하여 '공사의 분할 및 분리발주 시에는 행정자치부 장관 등 상급기관에 보고'토록 입법예고 되었으나, 우리협회는 분리발주 활성화를 위하여 '기계설비공사 분리발주 근거 조항인 단서3호는 제외'토록 추진함에 따라 우리 협회의 의견이 반영된 시행령이 개정되었다. 또한 하도급관리계획을 불이행한 원도급업체는 앞으로 부정당업자로 제재받아 입찰참가자격이 최소 1개월에서 최고 6개월 미만까지 제한된다. 이밖에 물가변동과 관련하여 단품슬라이딩제를 도입해 특정자재의 가격이 15% 이상 등락할 경우 계약금액을 조정할 수 있게 했다. 이중 지방계약법 시행령 제 77조 개정 내용의 의의 및 우리 설비건설업과 신.구조문 대비표는 다음과 같다.

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.

Delay schedule coming about duration extension is happening essentially because public construction project consist of many sub contractor. The method which can calculate delay day is suggested by many studies in case of happing delay schedule, but It is difficult to apply to real construction project because there is no mention about the control of The law of contract according to delay schedule. The law of Contract which is cost of account has more uncertain problem than FIDIC condition of contract. This study suggests method which can make extension of duration procedure clear in case of happing the reason of design change related with activity duration during carrying on construction, and a submission process of the reason of duration extension and modify schedule making way about section which is basis of calculating contract amount clear.
