올해부터, 국토해양부 장관이 고시하는 최저가낙찰제 대상공사에 대하여 포괄대금지급보증제도가 시행되며, 건설근로자 노무비 구분관리 및 지급 확인제가 추진된다. 또한 근로계약 체결시 근로조건 일반사항이 명시된 서면을 근로자에게 반드시 교부해야 하며, 장애인 고용부담이 강화된다. 본지는 올해부터 달라지는 건설 중소기업 관련 개편 시행되는 각종 제도를 소개한다.

현장에서는 주공정과 예산관리를 중심으로 공사진행을 하고, 공정이 90% 이상 달성되었거나 또는 잔여공기가 9개윌 정도 남아 있으면 모든 공정을 재검토하기 바란다. 우선 하청시로부터 잔여 공사에 대한 공정표를 받아, 잔여공시 1개월 전에 준공될 수 있는지 검토한다. 9개월 정도 앞서 준공기일을 검토하는 것은, 자재납기가 장기간(7개월 정도) 소요되는(플랜트 Control Panel 등) 자재의 발주여부를 검토하고, 잔여공기 내에 정상 작업으로 공기 내 준공이 불가하다고 예측될 경우, 3개월 또는 6개월 돌관작업 계획을 세우기 위함이다. 잔여공기가 3개월 정도 남아 있을 때, 시설물을 인계(Hand Over) 하기 위해 본격적인 준비를 한다. 준공이란 "계약적으로 발주자가 실제적으로 계약서에 의도된 목적으로 사용할 수 있는 상태(표준계악일반조건 48. 1)"를 말하므로, 이 점에 착안하여 발주자가 시설물을 제때에 사용하지 못함으로써 발생되는 지체보상금(Liquidated Damage)을 물지 않도록 작전을 세운다.

In defense and military facility projects, adjustments to contract amounts due to design changes directly or indirectly affect factors such as increased construction costs and extended construction periods. Moreover, they can lead to differences of opinion and conflicts between the military and contracting parties. This case study analyzed the integrated management of defense and military facility projects by the Gyeonggi Southern Facilities Division, which oversees projects in Seoul and the southern Gyeonggi Province region for the Army, Navy, Marine Corps, and Air Force. Out of 388 completed projects, 103 cases with design changes were selected for analysis, aiming to ensure the reliability of data regarding the proportion of design changes in project completion. The study classified samples by the causes of design changes specified in the Ministry of Planning and Finance's contract regulations, assigning rankings based on the occurrence rates of each cause. Furthermore, it analyzed detailed factors for each cause of design change and derived implications to propose improvement measures. Considering the limited access to military primary data, this case study is expected to contribute to minimizing design changes in defense and military facility projects. Additionally, it is anticipated to be practically useful for subsequent research on contract amount adjustments resulting from design changes.

Recently, many Korean major construction companies are suffering from profit loss mainly due to a direct impact from delays in their overseas projects. In general, changes are inevitable in a large-scale project, and most of changes are directly linked to construction delay. Therefore, in the event that an extension of time is necessary due to a change, the contractor must manage the delay based on the condition of the contract to effectively manage risks from delay to the completion date. Thus it is important to understand delay protocol defined in the condition of the contract early in the project, but there have been few or no study to propose methodology or tool to support this effort. This paper presents a review on the project planning and controling practices of major Korean construction companies along with the issues on delay claims and disputes in mega-international projects and suggests a tool to assess delay risk in the condition of the contract. To propose a delay risk assessment model for international construction projects, major standard conditions of contract have been reviewed including FIDIC Red Book(1999), PSSCOC(2014) and SIA 9th Edition(2010). To reflect recent trend of major international owners, standard conditions which they are utilizing for their projects also have been reviewed including those of ARAMCO and QP. The model provides a categories of risks to be reviewed on the condition of the contract along with standard level of the risk which is common in the international standard form of the contracts. This study also performed a case study on an actual international project to confirm the effectiveness of proposed model to identify and respond to a delay risk of a project.

There are several causes to recalculate the contract amount in public construction projects. Among them, the escalation clause was introduced in 1969 and now the condition to recalculate the cost is effective after 90 days from the date of contract and the rate of fluctuation should be more than 3% from the date of bidding. The two calculation methods for the rate of fluctuation are item-adjustment and index-adjustment. According to the results of investigation into 4 public institutions and 163 projects, all of them have used the method of index-adjustment and the rate of projects that spend over 6 months obtaining the approval of contract amount adjustment is more than 90%. The reason for spending lots of time is caused by problems of the calculation method on the price fluctuation rate. Therefore, it is necessary that the calculation method should be diversified to cope with the problems and a option of the builder should be expanded as well. Furthermore, if the way to apply correction factors to construction price index and average index based on the producer and consumer price index made by the bank of Korea is added, then the duration will be reduced without additional expenses. This study proposed the diversification of the calculation method using price fluctuation rate and builders' expanded options as improvement on the managerial method of Price Fluctuation System for the prompt and efficient contract amount adjustment.
