This paper presents an automated construction quality nonconformity control method. Existing quality control process are confined attributed to the dependence on human quality personnels. They are inefficiency for continuos quality improvements and may cause project schedule delays when any nonconformity is handled timely fashion. For sure, It is important to identify the add hoc quality nonconformity control processes and to implement them into an automated system that controls its' work-flow. It would be desirable to develop the construction project quality nonconformity control system using Building information modeling(BIM) and Information and Communications Technologies(ICT). It may provide an effective platform to prevent quality issues that exist in the existing quality management practice.

Although the Korean construction industry has risen rapidly, the quality of the buildings is not met with the industry standard compared to the potential of the technology development and the cost of maintenance has been increased. The user's request for quality have been increased, but in the current building construction, the contractors only follow the specifications of design, material and technology, and their main concern is whether they are in right track with the specification or not. Thus, the necessity of developing technology has been ignored and sufficient opportunities for the development have not been provided as well. In the developed countries, in contrast, the quality assurance and the payment regulation system has been utilized for the active response to the changes of users' request. As a result of this, the maintenance cost has been decreased and the development of construction technology has been improved. Therefore the pay adjustment system is needed to create the improvement of the quality of the buildings by the contractors' earnest building construction. In order to introduce the pay adjustment system suitable to the Korean construction industry, this study presented the logical method of adjusting the construction cost and making payment with the pay adjustment index that is created based on the result of the performance test, after making a set of the indicators of the building performance standard and applied them to the targeted building.

Construction projects are getting more complex and larger-sized with a high economic growth rate and development of new construction technologies. In addition, interests and demands on standards of construction quality are further increasing. This trend requires more systematic and a higher level of construction quality management. While the government has strengthened the regulations for quality assurance, many quality problems have repeatedly occurred mainly due to lack of recognition for quality management and quality control systems. To address this issue, this paper aims to suggest quality management improvement scheme through analyzing 3,443 nonconforming items identified during inspection of 393 construction sites from March 2012 to October 2014. The quality management improvement scheme suggested in this research is expected to prevent quality problems and defects and thus improve construction performances.

For successful waterproofing construction, it is very important to secure construction quality as well as material performance of waterproofing materials used in construction. Due to the long-term cost reduction policy following the economic downturn in the construction market, most construction companies are using general low-priced waterproof materials rather than high-quality waterproof materials without clear quality control standards. Without clear education on construction, construction is being carried out with meaning only on construction activities. In addition, the waterproofing method applied in combination is a situation where water leakage occurs due to waterproofing failure due to insufficient construction quality because the construction method is complicated. Therefore, it is necessary to review the quality control measures(design, materials, construction) for successful waterproofing work and improve problems that are derived so that stable waterproofing work can be done. In order to expect the leakage prevention effect of a building, first, it is required to select appropriate materials for each part of the building and environment in the design stage, and the selected materials must satisfy all items of the Korean Industrial Standard(KS). Second, to secure the quality of waterproofing construction, sincere construction by workers is required. In this paper, we tried to describe "review of waterproof design", "constructor education", "site inspection", and "criticism(correction/supplementation)" as quality control measures after material selection.

The construction industry in Korea has seen significant improvements in quality management techniques, driven by the dramatic development of new technology through Manhattanization and enlargements, but compared with technical development, the level of building quality improvement is still lagging behind. In the meantime, as the interest in construction quality soars due to changes in user consciousness, the level of quality that is being demanded is rising. The government has reinforced quality systems by implementing responsible supervision requirements and granting overseas companies permission to enter the supervision business in Korea, and private sector companies also are attempting quality improvement through quality assurance approaches like the preliminary qualification screening system and ISO 9000 series. But currently, building constructions are done only according to the construction specifications of project owners, whose design, materials and construction methods are already decided, and do not leave any necessity or opportunity for technical developments for the quality improvement of contractors. Therefore, in this study, a work process and system improvement plan for payment regulations is proposed, with which contractors can secure quality voluntarily in the building construction phase.

The aim of this study is to improve quality system through mutual understanding for the opinion gap among interested parties such as owner, designer, constructor and supervisor in construction industry. The survey to the owners, designers, constructors, and supervisors who are in charge of quality of the 183 architectural projects being constructed has been performed for investigating the importance and actual level of quality and quality factors. Questionnaires are based on the quality factors shown in ISO 9001:2000 international quality management system requirements. There are distinct opinion gaps for quality among owner, designer, constructor, and supervisor who working for the same architectural projects.

US transportation agencies are dealing with shrinking budgets, limited work forces, and deteriorating infrastructure. In order to cope with funding uncertainty, state highway agencies are now looking into their own organizations and identifying programs, practices, and processes that have potential for cost saving. A quality assurance (QA) program is an integral part of highway construction and ensures a project's contracted level of quality. The cost of quality (conforming and nonconforming) can constitute a sizable part of total construction cost. As the quality assurance programs evolved, various practices and processes were developed over time and later adopted by state highway agencies. These practices and processes include different QA standards and specifications, varying testing methods, central testing lab vs. on site testing, performance based vs. prescribed quality assurance practices, implementation of innovative quality assurance practices, etc. Therefore, there is an opportunity to assess different QA strategies and recommend those practices that are effective and cost efficient. A national survey was conducted by the authors, which provided a detailed mapping of various QA practices and processes used as part of QA programs and identified areas where agencies can focus on for cost savings. The survey found that QA sampling and testing plans, optimization of sampling plans, optimization of QA standards and specifications, and implementation of innovative test methods and processes are the main areas the agencies should focus to lean the current QA programs.

The comprehensive Topic of Total Quality Management (TQM) has been put forward since the 6^th decade in industrial countries. The serious attention to it in developing countries goes back to recent years. Unfortunately serious attention is not paid to quality issues in building industry. Therefore, the construction of buildings is highly vulnerable against natural events while having low effective lifetime. Wide-range destruction of the residential buildings in the earthquake of Bam ( in IRAN ) is a clear proof for this claim. In this paper we tried to present the corresponding effects between quality issues and other aspects of a building project (such as costs) and proposed general solutions to improve quality indices in construction industry.

Importance of quality control is gradually increasing in the construction. And the reber work is very important things which influence in safety and durability of the building and accounts for about 9.8% of the total cost. Although reber work is important, quality control of the rebar work is still performed by attitude and experience of worker. Therefore, it is very important to quality achievement effort and quality standards recognition of rebar worker for quality sophistication in the construction. Some papers have dealt with the quality control in construction. But there was no study for actual conditions of quality standards recognition of rebar workers. The purpose of this study is to survey the actual conditions of quality standards recognition of rebar workers and to analyze difference of consciousness of administrator and worker. The result are : there id difference of consciousness of worker and administrator, workers work without knowing quality standard.
