Modern society is developing rapidly due to the convergence of industry and IT technology. In that case, the role of construction work that provides basic infrastructure can be very large. Recently, as construction work becomes more complicated, larger, and more advanced, the importance of management, such as system improvement for quality improvement, has become even more important. However, when a quality control problem occurs at a construction site, much time is required to solve the problem. In order for a construction project to be successful, various systems need to be organically connected and able to manage optimal decisions. In this paper, provide a quality control model using GCM push alarm service based on RESTful_API. The proposed model is a model that can be used by construction company quality control rooms and project managers for decision making. When applied to construction site project management, it is expected that more efficient and safe construction management will be possible.

Document managements are very important in internal communication for good performance on projects. In case of small scale projects, the document management criteria often have very different from each of the cooperation departments and changes of document structure of work process are frequent over a project period. In this thesis, we propose a monitoring system of document management which is based on P2P(Peer-to-Peer). The proposed monitoring system of document management, which is based on P2P, makes up for time limits and a specific work process in small scale project groups. It can be managed focusing on work process and can monitor effectively the status of creations, sharing and distributions of documents. We can be installed at a low cost by using P2P in a small scale project.

This study aims to systematically identify direct and indirect factors that influence labor productivity and to build a model that mathematically quantifies them so as to efficiently manage and increase labor productivity in the construction work. This study was performed based on the productivity model for workers in reinforced concrete construction projects, because it aims to establish a general construction labor productivity model that reflects many factors that influence labor productivity. Using statistical analysis, we found that the components that significantly influence productivity were the worker component, the work characteristic component, the work technique component, the work management component, the equipment & materials component, and the work guide component, while the work delay components did not significantly influence productivity. In addition, a priority analysis was performed based on the components that showed statistically significant effects. The results of the analysis indicated that the influence of work management component and the work technique component is more than that of the worker component and the work characteristic component. The construction labor productivity model that was formulated in this study could be used for the determining the standard productivity during the initial planning stage, so the best strategy for increasing labor productivity could be formulated.

A submittal, as a part of three main project management processes: production control, submittals and change orders, is the transmission of information from the subcontractor to the general contractor to the owner, architect, and structural engineer, for review and approval. The purpose of the submittal process is for submittals to be approved in order to start construction. This benefits the contractor by ensuring that the finished project will meet the expectations of the owner. This paper analyzed a case study regarding the submittal process for the local-based environmental construction company, which typically works as a subcontractor and may hire other subcontractors for additional work when applicable. The aim of this study was to roughly evaluate a project management process and understand the submittal process through the study of a case involving the local company.

The purpose of this study is to construct a new model named Communication Consensus Value Weighted (CCVW) model based on inter-personal technical communication within a project team, and to design Feasibility Estimates Integrated Terminal System (FEITS) which is a subsystem of R & D Project Planning System/System Alternatives Feasibility Estimation System (RDPPL/SAFES) using the model as a key function for feasibility estimation in that system. This new model aims to integrate technical feasibility estimated by several estimators in the lowest level as the project work breakdown structure which is the indentical conception of a terminal system in RDPPL. The process to obtain the feasibility estimate integrated is presented in this paper.

The factors of uncertainty such as work delay could cause many problems, for example, increase of construction cost and terms of work, and the deterioration of quality. Because of these, the uncertainty risk is regarded as an important management factor to obtain the success of construction project. So, the systematic management plan about the uncertainty factors is needed because it plays an important role in the completion of entire project. And also analysis of some factors which can cause the work delay can be one way of improving construction project's certainty and making it competitive. In this reason, we have to make an effort to set a priority based on analysis of quantitatively numerical value about work delay factors to manage them effectively. Thus, this study aims to suggest the basic data for the effective management and prevention of work delay in steel-frame work which is progressive actively now, along with increasing of demand of high-rise buildings by analyzing each reasons of work delay factors and also by suggesting important management factors that are coded according to each construction work using FMEA method which could give a data about the importance of work delay factors through quantitatively numerical value.

Construction documents are recognized as an essential component for making a decision and supporting on construction processes. In construction, the management of project document is a complex process due to different factors such as document types, stakeholder involvement, document flow, and document flow processes. Therefore, inappropriate management of project documents can cause several impacts on construction work processes such as delay or poor quality of work. Several information and communication technologies (ICT) were proposed to overcome problems concerning document management practice in construction projects. However, the adoption of ICT may have some limitation on the compatibility of specific document workflow. Lack of understanding on designing document system may cause many problems during the use and implementation phase. Thus, this paper proposes the framework that integrates Soft System Methodology (SSM) concept and Integrated Definition Modeling Technique (IDEF) for analyzing document management system in construction project. Research methodology is classified as the case study. Five main construction building projects are selected as case studies. The qualitative data related to problems and processes are collected by interviewing construction project participants such as main contractors, owners, consultants, and designers. The findings from case study show the benefits of using SSM and IDEF. The use of SSM can help identify the problems in managing construction document in rich picture view whereas IDEF can illustrate the document flow in construction project in details. In addition, the idea of integrating these two concepts can be used to identify the root causes of process problems at the information level. As the results, this idea can be applied to analyze and design web-based document management system in the future.

BIM technology, based on 3D model of civil engineering structures, creates and manages information of the structures throughout four stages: Planning, design, construction, and maintenance. BIM is now used around the globe for improvement of the construction productivity. However, in order to expect the efficient engineering work, collaboration system between participants in a construction project is necessary. Therefore, in this paper BIM based CPLM (Construction project lifecycle management) system was designed and developed by analyzing the requirements of participants of a construction project. CPLM system offers an environment which enables the sharing and management of information according to the each stage of construction. CPLM is expected to aid cooperative decision-making during the overall construction process through the process innovation and the efficient data management.

The management of daily work report is very important due to the variety of work trade and activities. Although various project management systems have been developed to effectively deal with various task in site, they are not in practical use due to the non-coorperative attitude of sub-contractors. This is the reason the system are not developed in the focus of sub-contractors, but main contractors and the detail information about daily work report is omitted or lost in the collection process by contractors. Therefore the purpose of this study was to propose the Web-based coordination system for daily work report between contractor and sub-contractors

In this paper, we propose a project-based learning using Arduino as an example of embedded system class in engineering students. By introducing these Project-Based Learning(PBL) into engineering education, students became able to actualize individual theories that they had learned through their major curriculum and they were given the experience to build up their field work ability by participating in the whole project development process. We conducted a questionnaire survey to investigate the education effect of PBL before and after class and the results were analyzed using SPSS statistical program. Since PBL is mainly operated by a team system, communication skills and teamwork within the organization can be improved through interactions among the members. All of the materials produced during the course of the project could be used to make portfolio of students, which could be of great help to data for employment activities after graduation.
