The purpose of this study is to ensure an amicable material quality control in the construction site through investigating a process which can impact the construction material quality. For it, a worker interview and questionnaire survey was conducted through a direct field visit. The visited construction sites are composed of 79% construction site and 21% engineering site. As the respondents of questionnaire survey, the quality control workers were 72% of total respondents. Next, the construction worker, handymen, field representatives and others formed 7%. The interview with the quality control staff was conducted with the items including the construction site quality control guide, incoming inspection and material management. Through this survey, the problems of quality control by progress phase were derived. It could be known that the management and measures by each phase were urgently required. It also was indicated that a selection of low-priced material caused by low price bidding could badly impact the construction and safety. Also, in relation to the opinions such as the insufficient quality control and heavy work-load, the improvements are required. For the effective quality control in the construction site, the material quality control procedures suitable for the phase of construction progress must be presented in the present quality control. Also, the standards for it need to be established.

General criteria for the quality of porous concrete have not been established yet in Korea. And yet, pavement and construction have been performed. In this paper, guidelines on the construction site quality control of porous concrete were developed in order to establish criteria for resolving the issues and problems of porous concrete, to establish methods for improving poor performance, and to manage porous concrete more systematically. In addition, a guide for the construction site quality control of porous concrete, which was appropriate for reality, was developed by researching several quality control guides and maintenance at construction sites. The guide consists of a total of nine chapters such as Application Range, Overview, the Structure of Porous Concrete, the Design of Package Thickness, Package Materials for Porous Concrete, Construction Methods, Quality Assurance and Inspections, Construction Site Quality Control, and Maintenance. It describes quality control guidelines in all steps such as methods for transporting porous concrete from the factory to the construction site, cautions for construction work at construction sites, maintenance, and management. The Guide for the Construction Site Quality Control of Porous Concrete is expected to ensure the quality of porous concrete, to reduce national costs for quality assurance, and to help ensure the health and safety of Korean people.

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.

Ecological Engineering (EE) refers to all sustainable engineering that can reduce damage to ecosystems and that adopts ecology as a base and safety as an orientation in order to implement conservation of biodiversity and sustainable development. In short, EE attempts to safeguard the ecological environment while any essential construction projects proceed. EE encompasses many fields, including construction skills, ecosystem preservation, landscape, and even related cultures and so on. Such variety results in greater complexity of construction, and, consequently, indirectly increases the difficulty of construction quality control. The objective of our research is to explore a promising model for EE via an extensive literature survey. This model includes three principal stages: plan-design, construction, and maintenance, along with individual accompanying phases concerned with quality control and vital management. In this article, a river restoration example is adopted to describe in detail the critical points of quality control in the three stages (plan-design, construction, and maintenance) of the construction life cycle. This study proposes an integrated structure for quality management of EE to guarantee its quality and to enhance its core applications in order to achieve long-lasting preservation of the environment.

The construction industry consists of various and massive architectural information as an architectural process includes a variety of design stages with cooperation of many disciplines. Particularly, architectural information is generated and managed through the life cycle of a building, from conceptual design stage to the construction and maintenance. A Building Information Model (BIM) serves as a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle from inception onward. BIM technology accomplished quantitative development being utilized in various disciplines. However, it is necessary to develop environment and requirement for qualitative improvement of BIM based project. Particularly, requirement is very important for architectural design evaluations. The purpose of this study is to develop and apply of quality control requirement for improving the quality of architectural design in open BIM environments. To achieve this purpose, the authors have investigated case study for open BIM data quality control (software, guideline and application case) and classified quality control targets according to physical/logical quality and data quality. In addition, the authors have defined open BIM based quality control process and developed quality control requirements. Finally, the authors have developed rule based quality check system using requirements for efficient quality control based on open BIM.

본 연구에서는 연약지반의 개량 및 부등침하가 일어난 건물의 복원 등에 사용할 수 있는 컴팩션 그라우팅 공법을 소개하였다. 기존 컴팩션 그라우팅 공법에서 사용되는 펌프는 1공씩 주입하는 시스템으로 시공 효율성이 저하되고,아날로그 주입방식으로 현장 작업자가 수동으로 시공을 관리하여 일관된 품질관리가 어려웠다. 기존 시공에서의 문제점을 해결하기 위하여 펌프와 품질관리 시스템을 개발하였다. 품질관리 시스템은 주입재료의 자동 배합 시스템, 다중 동시 주입 펌프, 주입관리 모니터링 시스템으로 구성하였다. 현장 시험을 통해 품질관리 시스템의 성능을 검증하였고 컴팩션 그라우팅 공법의 시험시공 후 품질 시험을 통하여 지반개량 성능을 확인하였다. 따라서 개발된 통합 품질관리 시스템을 활용한다면 시공 및 품질 확인이 어려운 현장에서 일관된 품질의 보장과 시공의 효율성 및 안정성을 향상시킬 수 있을 것으로 기대된다.

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.

건설공사의 품질관리 관련자는 품질관리계획 또는 품질시험계획을 수립 및 시행하고 공정에 따라 사용 자재의 적격 여부 확인, 시험 검사 장비의 관리, 품질교육, 자체 품질점검 및 조치, 부적합 제품 공정에 대한 지도 관리 및 품질시험 등을 시행하고 부실공사를 방지하여 사고를 예방하는 중요한 역할을 담당하고 있다. 그러나 관련기관은 품질관리 관련자에 대하여 관련 법 규정의 개정 시 시험요원, 품질관리자 등으로 호칭을 변경하면서 품질시험과 품질관리 업무에 대한 역할분담을 명확하게 제시하지 않았으며, 건설공사의 품질관리비 산정 및 인건비 적용 등에 혼란을 유발하였다. 따라서 이를 개선하기 위한 연구가 필요하다. 본 연구에서는 품질관리 관련자에 대하여 모호한 호칭관계를 관련 법 규정 등을 토대로 건설공사의 요구사항을 충족할 수 있도록 개선하고, 각각의 역할 및 호칭에 대하여 '품질시험자'와 '품질관리자'로 구분한다. 즉, 건설공사 품질관리 업무지침에서 규정한 "건설공사 품질시험기준"의 품질시험을 실시하는 자를 '품질시험자'로, 건설기술 진흥법 시행규칙에서 규정하는 품질관리계획 수립 및 시행업무를 수행하는 자를 '품질관리자'로 호칭하도록 규정한다.

모듈러 건축프로젝트는 공장제작을 통해 기존 건축공사보다 품질관리에 유리하다. 하지만, 품질관리활동에 대한 명확한 기준과 정의가 확립되지 않아 품질관리비용 규모의 적절성을 판단하기 어렵고, 프로세스 단계별 품질관리활동을 구분하는데 어려움이 있다. 이에, 본 연구에서는 활동기준 중심의 품질관리활동 분류방안을 제시하였으며, 품질비용을 PAF기준에 따라 분류하여 추후 해당 비용 및 활동이 품질관리에 얼마나 효과적인지 확인할 수 있는 방안을 제시하였다. 본 연구는 추후 모듈러 건축프로젝트 단계별 품질관리활동을 정의하고 이에 따른 비용 분배 적절성을 판단하는 근거자료와 데이터베이스를 추구하는데 활용될 수 있다.
