Modular construction projects offer advantageous over conventional construction projects in the area of quality control through factory production. However, as clear standards and definitions for quality control activities have yet to be not established, it is difficult to judge the appropriateness of the scale of quality control costs, and it is also difficult to classify quality control activities by process stage. Therefore, in this study, a method for classifying quality management activities based on activity standards was presented, in addition to a method for classifying quality costs according to the PAF standards to check how effective the costs and activities are for quality control in the future. The findings of this study can be used to define the quality management activities for each stage of the modular construction project in the future, and to develop a database of evidence to determine the appropriateness of cost distribution accordingly.

Korean government is promoting "K-Smart City" to overseas market which is an integrated solution of construction industry with ICT(Information and Communciations Technologies) industry. Due to nature of Smart City, construction quality and the development quality of the facilities need to be established to improve the overall quality. However, guidelines and regulations to initiate quality control for Smart City are behind the actual demand. This deficiency is bringing quality control for construction and ICT to be controlled separately causing lack of synergy and resulting in overall quality degradation. This research is designed to improve the construction quality of Smart City during its establishment stage by integrating ICT system with on-site construction (Integrated control center and on-site equipment). The adoption of this research to a real Smart City case had resulted in 22% reduction of construction inspection failure (Audit), and also allowed Construction Company to pre-align quality control of all purchased items of ICT Infra that resulted in 18% reduction of nonconformity, thus contributing to an overall quality improvement. This research is expected to be used widely among all construction industry of Smart City.

It is very important for performance of information system that we make an effort to raise user's satisfaction by continuously grasping user's requirement by evaluation of PMIS based on ASP service quality and reflecting this to information system. However, It is lack that developments of suitable evaluation index of PMIS based on ASP service quality. Hereupon, In this study, we propose the evaluation indicators. First, The evaluation area is classified by form the foundation of D & M IS Success Model (2003); system quality, information quality, service quality. Second, The detail evaluation item which include considerations which are gotten through investigation of the construction industry and PMIS based on ASP is grouping by form the foundation SERVQUAL which is a service quality evaluation tool proposed PZB(1988). It is suitable to evaluate PMIS based on ASP service quality in construction industry and able to evaluate various aspects.

The automated construction machines have been recently developed to help solve the construction industry problems that significantly affect labour, productivity, quality, and profit. Despite the importance of performance analysis to commercialize the automated construction machines, previous studies have mainly concentrated on developing hardware and software of automated construction machines. This research now focuses on two objectives: (1) to propose an analysis model which can measure productivity, quality, and safety improvement rate of automated construction machines based on research and development (R&D); and (2) to develop a performance analysis system which will aid the evaluator in analysing the performance of automated construction machines. Finally, it is anticipated that the effective use of the performance analysis model and computerized system will ably develop the high-performance, automated construction machines and establish the marketing strategy to increase not only the commercial value but also the upkeep and development of construction machines.

The several smart construction technologies are being introduced to the construction industry, and among these technologies, a few companies are attempting quality control using 3D scanning and BIM. Therefore, in this study, 3D scanning and BIM were applied to cases of on-site quality inspection to confirm the applicability and utility. As a result, it was confirmed that the quality inspection using 3D scanning and BIM was shorter in time than the previously performed quality inspection and can be realized with less manpower. Therefore, it is considered that 3D scanning and BIM-enabled technologies can be applied to various items of quality inspection.

Generally speaking, it is important to know the activities itself exactly and to control the activities correctly so as to assure timely progress and the quality of any project. In order to progress smoothly in accordance with construction schedule, it is important to systematize the preliminary arrangements necessary for each process and then manage them. In this study, in order to progress smoothly the quality and schedule management of the construction, we can be made systematically pre-works in accordance with construction schedule by the civil construction items of the apartment house construction. we suggested pre-construction control item by the workers through experiential method of construction engineers in accordance with network schedule.

We can agree that Quality Control in manufacturing industry have been improved successfully, but in construction industry, for example Sungsoo-Bridge broken out, Sampung Department store collapse, subway construction site explosion. and etc, it is difficult to be done. Because in manufacturing industry, they complete each other. If quality is not good. products aren't sold out. to sell more products they have to improve their products quality by themselves. However in construction industry they don't effort to improve quality if they get an order. Because if they get an order only completing their product is their job. There are engineering side, culturing side, and educational side to improve product quality. In this thesis I investigated evaluation system in construction industry. I am going to propose evaluation system by which they have effort to improve the quality even in construction industry.

A variety of studies on concrete have been performed to examine the advantages for structural material, but less attention has been paid to the contribution of concrete to finishing. Due to this matter, specific management guidelines for construction and quality on exposed concrete have not been clearly established despite more construction cost and quality control are required. This study analyzed a impact factors on the quality by survey of the existing research and practice. Field tests were performed using mock-up models to analyze the quality of exposed concrete according to form manufacture method, concrete mix proportion, and concrete placing method. Results indicate that the quality of exposed concrete was determined by concrete mix proportion and construction managements. Guidelines of quality control on exposed concrete in construction stages were proposed.

A high rock embankment by means of dynamic compaction has hardly carried out in domestic area. For the successful accomplishment of such a high rock embankment, construction quality and measurement control are conducted. Plate loading tests are carried out to verify the bearing capacity and safety against the long term settlement. In addition, settlement of each layer is measured in order to verify the effect of dynamic compaction and to predict long term settlement.
