Civil appeals under constructions cause a lot of difficulties of doing construction because of compensations, interruption of works, administrative punishments, etc. So this research focused on the characteristics of civil complaints against constructions by analyzing the causes of civil appeals and treatment conditions classified by year, geography, and breaking time. This research indicates three points. (l) As the level of civil life and consciousness is increased, the number of civil appeals against constructions are tending upwards in view of the results so far achieved by year. (2) Analysis about civil appeals classified by geography shows that the rate of civil affairs in Gang-nam District are higher than that of others.(3) 96% of the civil appeals by breaking time are occurred under the constructions. By predicting and treating of what type of civil appeals are occurred, this research can be used as data which make damage minimized.

To analyze the present state of buildings suspended in Gangwon and estimate the compressive strength by visual inspection and Schmidt hammer method in order to analyze durability etc.. In this study, we analyzed the problems that existed in the location where construction is suspended and efficient management method. Expected construction restoration of construction will be restarted, and important parts of the construction site should be given the best protection measures so that the quality can be maintained thoroughly. The construction of the suspended construction is exposed to the freezing and thawing damage over time. Therefore, it is necessary to take measures such as maintenance, and take protective measures by establishing a plan to improve the durability of buildings that are under construction.

족하든 당시에 규정한 공사감리보수의 적절한 변동이 당국에 의하여 조정되여야 할 것이며, 건축사의 업무상 또는 건축을 뜻하는 여러분을 위하여 다소나마 도움이 될까하는 마음에서 붓을들어 본다.

Since 2004, the government has changedthe cost estimate system to one of an actual cost basis in order to calculate the optimum construction cost by reflecting changes in circumstance on the construction site in a timely manner. Currently, this is being applied to public construction work forover a billion won of actual cost data in estimation by contract unit cost. However, directly reflecting actual cost, which for large-sized construction work was originally an average unit cost, to a small building, entails the application of a low discount rate for the cost of materials, labor, etc. and therefore can frequently give rise to cases in which the actual cost of work performed exceeds the contract sum, which in turn causes problems such as decreased revenues, bad effectson business operation, productivity, etc. Therefore, to apply actual cost to small-sized construction work (less than a billion won), there should be a plan to modify unit cost in a manner that can reflect project scale, etc. in order to resolve the problem of unit cost application of actual cost to small-building construction projects. The unit cost modification model for proper actual construction cost in small-scale construction projects developed by this study will help to increase the relevant productivity and proper gain, preventing the aggravation of business operations. Organizations placing orders are also expected to be able to secure a more realistic construction cost in arranging the budget.

This study reviewed the existing legal framework governing construction supervision practices and conducted a survey of expert groups to identify and propose strategies for facilitating the digital transformation of construction supervision processes, with the goal of enhancing the quality and safety of construction projects. The research underscored the necessity for digital transformation to improve quality, safety, and efficiency of construction supervision. Additionally, it highlighted the need for greater consistency and clarity in terminology related to construction supervision. The study also presented recommendations for improvement, which included: establishing a structured supervision checklist to ensure safety and compliance, establishing a specialized construction supervision corporations subject to qualification screening, and introducing evaluation criteria to encourage the adoption of digital transformation technologies in construction supervision. The findings of this study are intended to serve as the foundation for future policy and regulatory frameworks aimed at promoting the digital transformation of construction supervision practices.

The purpose of this study is to derive risk events that occurred during aircraft runway construction and analyze loss costs for project participants. For this purpose, design change data, contracted statement and completed statement were investigated. The results of this study are as follows: There were 12 risk events in the process of construction, 5 design errors and 7 construction errors. The increased construction costs due to such risk events were calculated as KRW 726 million. Of the KRW 726 million that was increased due to risk events, about 52.57% was spent by the ordering agency, and about 47.43% contractors. The increased construction costs due to such risk events are about 4.86% of the direct construction costs of KRW 14.9 billion. Based on the results derived from these case studies, a method for estimating reserve costs and construction costs considering risk events is presented.

The purpose of this study is to investigate the perception of buildings suspended from construction and to analyze the problems that are inherent and effective in the management of public officials and residents in the area where construction is suspended. There are 63 buildings in the Gangwon area, 16% of which are occupied by the whole area. 31% of the apartment houses are occupied the most, and 10 years or more is suspended. 241 of them accounted for 62%. In order to efficiently manage buildings that are suspended from construction, protection measures should be taken to ensure safety and prevent crime through periodic and continuous management of facility grade management that conforms to the special act on safety and maintenance of facilities. Effective support for budget and personnel is required for efficient management of construction suspended.

For a holistic and precise assessment of safety benchmarks within a construction venture, it's paramount to delineate between the intrinsic features of the construction and its real-time, on-site performance metrics. In this study, we delved into genuine accident instances to discern the interplay between these construction attributes and on-ground performance determinants in relation to safety mishaps, employing the binomial logit analytical framework. Our scrutiny underscored that construction expenditure profoundly modulates the likelihood of fatal occurrences. Notably, variables pertinent to on-site safety protocols wielded considerable influence over both fatal mishaps and accidents implicating multiple personnel. These revelations intimate that while ascertaining the safety quotient of a construction initiative, a mere classification and recalibration based on fiscal dimensions can elucidate much. Yet, a comprehensive safety appraisal necessitates transcending quantitative indices, such as frequency of mishaps or casualty rates, to encapsulate the multifaceted interventions and strategies adopted at the construction locale.

HPC method is developing to improve the constructability and structural performance of the existing PC method. The objective of this study is to develop construction procedures and to analysis of construction period for HPC method. In order to develop construction procedures, the building construction data of the existing half-slab method was analyzed. Analyzing design drawings and specifications of nine construction cases, a prototype of half-slab method, was drawn. Applying the core technology of HPC method to the drawn prototype of half-slab method, a prototype of HPC method, was developed. The differences of both methods were 'installing PC column' and 'placing topping concrete'. To analysis the differences of both methods, seven construction cases were analyzed. According to the analysis for HPC method, cases1 and 2 had columns divided for construction shortened about 16% of a construction period. The schedule of column assembly work was analyzed to be shortened much. That is judged to be because the use of a hollow PC column leads to a decrease in the number of columns. In particular, if HPC method is applied to a building construction site using large columns, it is analyzed to shorten a construction period more than the existing Half-slab method.
