Construction project is necessary element for human life to upgrade the quality and convenience. However, due to its contradictory nature to the environment preservation, environmental pollution and damage, deterioration of natural scenery, noise/vibration, water quality pollution, etc. caused in the process of construction greatly affect the environment. For the building or construction project, its possible impact on environment during construction work and after completion must be predicted at its design phase, which will result in the completion of the architecture convenient for human being with its environmental pollution reduced to minimum level. In this study, the checklist of environmental factors was suggested, which should be taken into account at its design phase in conducting the construction work. Proposed checklist was linked with the developed web-based system for the convenience of users like designer and construction manager, etc. It is expected that the checklist suggested by this study will help the designer and construction manager to continue the steady development from the environmental viewpoint during the design phase.

Recently, as high level of interest for the city regeneration, large-scale projects are planned or being performed such as reconstruction project. These mesa-projects have different characteristics from a single project in the design phase. It is a number of companies involved in design phase of mega-project and principal decision-making entity manage the project from the initial stage of an ongoing business by coordinating an opinions between design companies. The absence of a decision making support system reflected those characteristic causes a variety of problems such as a loss of cost and schedule. Therefore the final object of this paper is to propose a decision making support tool and system interface.

Improving long-term performance in highway projects is an imperative goal for public administrations. Project delivery and procurement methods might provide an opportunity to align design and construction processes with this goal. Previous studies have explored whether project delivery methods impact the long-term performance of highway projects. However, these studies did not focus specifically on how core elements within the procurement might relate to long-term performance. Thus, this research aims to fill this gap by exploring to what extent and how long-term evaluation criteria are considered in design-build best-value procurement of highway projects. To this end, content analysis was conducted on 100 projects procured between 2009 and 2019 by 19 DOTs across the U.S. The analysis of 365 evaluation criteria found that (1) roughly 11% of them related to long-term performance. (2) The weight given to these criteria in the overall technical proposal was lower than 30%. (3) Sixty-five percent (65%) of long-term evaluation criteria focused on design while 15% related to materials and technology, respectively. The results of this study are a first steppingstone to initiate a deep exploration of the relationship between procurement practices and actual project performance. Currently, with sustainability and life cycle assessments being top concerns in infrastructure projects, this line of research might be of particular interest to DOTs and highway agencies across the U.S. and worldwide.

This study was executed by means of "user participatory design method", as a part of the public facility remodelling project supervised by the Seoul Municipality. This study aimed to complement and improve the methodology through reviewing the whole process of participatory design implementation and examining closely whether the activities, design methods and tools that have been applied at each stage were helpful to reflect the users' demands successfully. Given all of those, it implies; first, it is very meaningful that public facility remodelling project by "user participatory design" leads the ordinary users to have direct opportunity to participate in the public business and to change their perception of the restroom environment in school. Second, it is necessary to integrate the roles of the facilitator and the architect from the beginning stage of the process, which makes it feasible to reflect the users' needs to the final stage. Third, it is required to modify the design tools that enable non-professional participants to understand their tasks and to perform them effectively at the stage of decision making.

Precast concrete manufacturing has proved economies of scale through the repetitive production by means of standardization, automation, and prefabrication. Advanced digital design and fabrication technologies can empower its benefits by enabling mass customization in the building design and construction. This study analyzed five case studies in terms of 1) design intent and background, 2) module development and facade construction, 3) integrated process among project stakeholder. This article has attempted to establish the following three points in conclusion: 1) Form generating digital design tools such as Rhino, CATIA, Generative Component, and Digital Project were implemented to produce parametric surface pattern and rationalization to maximize existing precast manufacturing benefits. Also, BIM program has been used to promote coordination and communication among engineering consultants and contractors, 2) In addition to traditional precast concrete materials, GFRC, RFP, brick cladding precast and 3D printed mould have been introduced to reduce the weight and cost and to comply the code from the zoning, seismic, and fireproof requirements, 3) Design-assist contract, design-assist financial support, and co-location measures have been introduced to facilitate collaboration between architect, fabricator, and contractor from the beginning of the project.

Generally speaking, because of complexity of engineering process, the systems engineering may be not easy to understand clearly and not easy to perform also. The status of systems engineering infrastructure of the some Korean industry is not matured yet, i.e., the systems engineering process, method, tool and environment is not implemented consistently within the steel making industry. These difficulties are more severe at the concept and basic design phase than the detail design phase relatively. Korean industry has lots of development project for the precedented systems and usually has matured domain knowledge for the precedented systems. Even though there is a mature domain knowledge of the precedented systems, the development project will lead to failure under the condition of engineering system is not well equipped. For the project success, it is very important to have a proper engineering execution system especially for the concept design and basic phase, which has a high abstraction and a large influence on the whole project. This paper proposes a minimized design process that can be easily applied to the concept and basic design phase of the precedented systems, instead of complex system engineering processes. This paper also proposes the application case of the minimized design process and methods for a Blast Furnace System.

Global competition and reduced project life cycle ultimately puts greater performance requirements on the capital project delivery systems used to maintain competitiveness. Despite continuing improvements in delivery cycle time, business owners of facilities continue to demand greater improvements in project delivery cycle time. Therefore, it is very important to investigate the various techniques and methods leading to reduction in project cycle time and also identify the applicability of identified techniques and methods. This paper introduces reduction techniques identified through literature review (i.e, Schedule Reduction Techniques (SRTs), Management Techniques (MTs), and Construction Institute Industry (CII) Best Practices (BPs). In order to collect applicability of these techniques under different project phases (Pre-project planning (PPP), Design (D), Material Management (MM), Construction (C), and Start-up (SU)), the Essence Applicability Matrices (EAM) is used.

For half a century, PMM(Project Management Model) continually has been advanced by many researchers and managers. Especially, the model for civil and construct engineering has now high maturity, but the model for IT engineering has not acceptable maturity. PMI(Project Management Institute) provides the knowledge of protect management for general purpose, it is not adequate for IT prefect management without complements. In this paper, we propose IT project management model based the knowledge of PMI using UML. IT project management model provides not only functions for project planning, budgeting, design and Implement, but also the knowledge for managing IT protect efficiently. We use uses case diagrams to describe the details of the model. We expect the model to be used in management of IT project efficiently in public sector.
