In project projects where various factors arise, the construction company's initial establishment of a reasonable process plan reduces various variables and potential risks. In order to create a densely written initial process plan, it is necessary to compare the economic feasibility of time and money by reflecting Slack time. Through this, site managers can lead a successful project based on reasonable and stable construction.

Recently, construction project has greatly increased the needs for cost savings due to excessive competition and economic recession. The purpose of this study is to introduce application of building using optimal design technique for improving constructability and economic efficiency of structural wall. As a results, design results of irregular wall show about 15% reduction of the longitudinal bar compared to single walls and ultimately improve constructability.

This Study has empirically examined the relationship between the role of R & D project leaders and their team performance using data from 87 project teams in 6 R & d organizations. The results reveal that : 1) R & D project leaders play five different roles for performing their jobs-strategic plannar, team builder, gatekeeper, expert and champion : 2) all but the champion role of leaders are positively associated with project team performance unless they have too short team tenure to materialize their role efforts : 3) However, the relationship between the role of leaders and project team performance varies according to characteristics of their team and project tasks. More specifically, it becomes more important for leaders to focus on gatekeeping and championing roles as their team gats older. Team building role of leaders is more important for higher performance of relatively certain R & D projects, while for uncertain R & D projects gatekeeping role appears to be more important.

The block-unit housing renewal project was presented as an alternative method to overcome the side effects of large-scale renewal projects while improving poor residential conditions. However, projects implementation is prolonged and even the pace of projects, which was considered an various incentives, is being delayed for the most part. In this study, delay factors are drawn by eight; conflict among association members, contract delay of joint implementation, participation paucity of constructor, inadequate project guidelines, alteration of project plan, lack of renewal project professionals, stricter loan restriction of HUG, lack of capacity of project operator. We categorized those eight factors to three aspects such as implementation, participants and proposition and suggested improvement alternatives according to three aspects.

The objective of this study is to assess the requirements of tablet PC-based PMIS applications designed for use on construction sites to determine whether these new programs can play a significant role in increasing the efficiency of a project. In this research, the current market conditions of PMIS running on a tablet PC were analyzed. In addition, two industry surveys were conducted. A research team interviewed some industry experts and identified fourteen useful and desirable functions that can be incorporated into tablet PC-based applications and project management tools. Through a questionnaire survey, the most effective functions for the tablet PC-based PMIS were identified. The three top-rated functions among those suggested were Contact Information for Job-Related Personnel; Receive and Respond to Submittals, RFIs, and Notices; and Problem Solving for Design and Engineering Issues. The results of this research are expected to provide helpful information for mobile application developers and members of other interested groups in the construction industry.

In South Korea, there have been attempts to enhance BIM work practices in various aspects. Public Procurement Service(PPS) has recently published 'basic guidelines to improve BIM work practices in construction and facility management'. It defines roles and responsibilities of project members in their application of BIM. It also developed a set of modelling standards and guidelines for effective model creation, management and communication among BIM users. Moreover, numerous construction companies have tried to cultivate BIM specialized manpower throughout entire construction phases. However, there are still challenges faced by firms during BIM adoption. Therefore, this study aims to provide practical counsel for construction companies to help them create optimized facilities and deliver high performance by analyzing BIM-based domestic construction projects in Korea from 2009 and 2015. The study will investigate types of client, project, BIM application range, and application technology.

The Korean government makes an effort to raise the competitive power of nation through CM activation in the construction industry. Since the first CM service was applied to the atomic power plant project in 1986, the number of CM contracts are continuously being increased and will be up to 20% by 2002 in public sector. However, the public projects had been executed without any procedure manual or standard guideline of CM services. Meanwhile the Ministry of Construction and Transportation issued $\ulcorner$CM Service Guide$\lrcorner$, but the guide shows an indefinite description in the responsibility, authority and scope of activity for the project participants. Therefore, it is required the procedures be improved and scope of activities be established for the project participants. This study was generated from the comparative analysis of $\ulcorner$Standard CM Services and Practice$\lrcorner$ Published by CMAA and domestic $\ulcorner$CM Service Guide$\lrcorner$ and the case of Incheon International Airport construction. The purpose of this study is to provide the fundamental data for an improvement in the procedures of project execution and the construction manager's activities/rolls shown on $\ulcorner$CM Service Guide$\lrcorner$

This mixed-use Raffles City (RCH) development is located near the Qiantang River in Hangzhou, the capital of Zhejiang province, located southwest of Shanghai, China. The project incorporates retail, offices, housing, and hotel facilities and marks the site of a cultural landscape within the Quianjiang New Town Area. The project is composed of two 250-meter-tall twisting towers with a form of vibrant waves, along with a commercial podium and three stories of basement car parking. It reaches a height of 60 stories, presenting views both to and from the Qiantang River and West Lake areas, with a total floor area of almost 400,000 square meters. A composite moment frame plus concrete core structural system was adopted for the tower structures. Concrete filled steel tubular (CFT) columns together with steel reinforced concrete (SRC) beams form the outer moment frame of the towers' structure. The internal slabs and floor beams are of reinforced concrete. This paper presents the engineering design and construction of this highly complex project. Through comprehensive discussion and careful elaboration, some conclusions are reached, which serve as a reference guide for the design and construction of similar free-form, hybrid, mix-use buildings.
