According to the preceding research outcomes, feasibility studies on public construction projects were incorrect and subjective. To resolve the problems, Korean government initiated Preliminary Feasibility Study (PFS) system prior to undertaking the main feasibility study. The PSF can be categorized into four areas such as road, railroad, harbor, airport, and Culture & Tourism (C&T). Especially when it comes to complex due to the introduction of five-weekday working system and local
self administrative system. As a result, the standardization and legislation of the PSF can not be operated effectively. Accordingly this paper seeks to 1) identify actual condition of conducted PSF in C&T; 2) set up analytical model considering cost factor of economical efficiency and seek obstacles of PSF system; 3) suggest improvement plan for construction PSF projects.

The purpose of this study is to examine the problem of BTL(Build Transfer Lease) projects through comparative analysis on running costs, focusing on primary school, junior and senior high school education facilities, and then to provide useful information on the estimation of running costs by suggesting valid cost criteria. For this, eight schools from A and B consulting firms were sampled from capital region and other areas. Sampled schools were classified into four categories according to school grade, and running cost data are collected and analyzed from relative view points. The results of this study are as follows: 1) running costs which are analyzed by categories show some difference among sub-items, 2) major problems related to running cost prediction of BTL projects are revealed and improvement schemes are suggested for two groups (Owner and Project applicants).

As the amount of
emission in Korea is ranked 9th and the increasing rate of
emissions highest in the world, it is strongly necessary to devise methods to decrease the amount of
in each industry as the basis of establishing environmentally sustainable production system. This paper aims to identify the characteristics of
emissions from construction wastes throughout the simplified LCA (Life Cycle Assessment) and suggest the strategic guideline for the construction waste management plan to decrease
. As a result of LCA on the case of a high-rise residential building project, total sum of
emission generated from construction wastes appeared as 6,818,123kg-
emission per unit floor area as 21.01kg-
. The principal waste materials generating more than 95% of
are materials such as reinforcing bar, temporary materials, cement, ready-mixed-concrete, concrete products, and tile, which have relatively high unit emission rate of
in the process of production. Besides, more than 92% of
was generated from the activities such as structure work, plaster work, temporary work, and tile and stone work, which are generally executed in the early phase of the whole construction period. Reflecting these results, the guideline for the construction waste management plan was recommended. If the waste management plan is established considering the guideline suggested, there would be high potential to decrease the amount of
generated from construction wastes.

For the continuous growth of the construction industry and the increase of the global competitiveness, research and development of construction technology is necessary. However, the R&D investment of Korean government for the construction industry is not sufficient compared with other countries and the various policies for encouraging construction R&D investment need to be improved too. This research focuses on the promotion of the construction R&D by the private sector that is one of the principal body of construction R&D and also the final user of the developed construction technology. This research suggests three promotion directions for the construction R&D by private sector; (1) the direction of creating better R&D investment climate, (2) the direction of increasing R&D investment amount, and (3) the direction of fostering R&D activities immediately.

As the government has enforced recently the policies on the distribution of the housing, the construction cost of multi-family housing projects has increasingly become very sensitive and political issue. However, it is difficult to predict the construction cost in planning and design phase of the project because the Bill of Quantity of the multi-family housing projects was composed of breakdown structure based on each work package. To predict the construction cost in planning and design phase for multi-family housing projects in more effective and reasonable way, this study developed the cost breakdown structure based on spaces using Delphi method. The Cost Breakdown Structure (CBS) based on spaces for multi-family housing projects basically consists of three parts: (i) Building part; (ii) Non-building part; and (iii) Additional part. The characteristics of spaces in multi-family housing projects are fully taken into consideration. Then these three parts were subdivided into work packages in terms of work tasks. Additionally, the usefulness and effectiveness of Space CBS in this paper were validated by analyzing the BOQs of several collected sample projects and matching with Space CBS afterwards.

Because the construction is becoming bigger and the construction environment is rapidly changing, IT/IS(Information Technology and Information System) of the construction is recently suggested with the alternative proposal. So not only is a study progressed in the area of the BIM(Buidilng Information Modeling), VC(Virtual Construction) and CIC (Computer-Integrated Construction) but also of the information database of the construction for building the information infrastructure of the construction in the domestic construction. Because object-oriented 3D CAD improves the efficiency of a design work and includes the object information which can use with the base of the information database of the construction, it has the high value not only in the design level but also in the construction life cycle. But compared with the effect, the use of 3D CAD is sluggish in the construction. In this study, after surveying about lowly using 3D CAD on the point of AEC (Architect-Engineer-Contract), the result is analyzed with AHP(Analytic Hierarchy Process). So the aim of this study is to offer the base to find the solution of the Affecting factors about lowly using 3D CAD.

Korean Journal of Construction Engineering and Management, volume 8, issue 6, 2007, Pages 197~206
The age of synthetic correspondence against "development period shortening, high quality" is about to come. While the product is becoming complexation gradually and also diversification, life cycle of product gets shorted. Under the infinity competition age, the certain answer of "the survival of the fittest" is that the enterprise itself must be able to shorten development and delivery term, reduce product development and life cycle cost, and satisfy customer in performance and value. From this point of view, concurrent engineering's theory, which develops the process of product in the manner of repetition, parallel, and synchronousness, is realized as a important strategy instrument in construction. This study investigates and analyzes several examples in order to apply concurrent engineering successfully, and presents the decision-making model through the simulation about the factor affecting in each process.

The efficient vertical lift planning has been brought into relief in high-rise building construction projects. Particularly, the selection and stability examination of the tower cranes is the most important elements in vertical lift planning. Therefore, professional knowledge is needed to full fill the site condition for the plan. However, there are short of the number of specialists and information about tower cranes. This study proposes a system for the selection of the optimum tower cranes (Opt-TC) in high-rise building construction projects. The Opt-TC can give the selection and stability examination of tower cranes at once in real-time.

Kim, Jin-Lee ;
Korean Journal of Construction Engineering and Management, volume 8, issue 6, 2007, Pages 235~245
This research study presents the development and application of an Elitist Genetic Algorithm (Elitist GA) for solving the resource-constrained project scheduling problem, which is one of the most challenging problems in construction engineering. Main features of the developed algorithm are that the elitist roulette selection operator is developed to preserve the best individual solution for the next generation so as to obtain the improved solution, and that parallel schedule generation scheme is used to generate a feasible solution to the problem. The experimental results on standard problem sets indicate that the proposed algorithm not only produces reasonably good solutions to the problems over the heuristic method and other GA, but also can find the optimal and/or near optimal solutions for the large-sized problems with multiple resources within a reasonable amount of time that will be applicable to the construction industry. This paper will help researchers and/or practitioners in the construction project scheduling software area with alternative means to find the optimal schedules by utilizing the advantages of the Elitist GA.

The performance of projects has always been an area of interest in the construction industry. Roles of all construction supply chain partners are necessary; however the role of a contractor firm in the construction project is pivotal. So, this research intended to explore a Construction Firm's performance criteria which could measure the level of performance of that firm in an ongoing project. Data was collected from construction professionals working in three principal project participant organizations, namely Owner, Consultant and Contractor. A total of 113 nos. of performance measuring items were sorted from literature review and used to collect data. Statistical tools processed by SPSS program was employed to analyze the data. Out of total 113 items, only 65 nos. of variables were found to be acceptable to every population group of this study. Factor analysis revealed 12 key performance predicting factors (KPPF) with 53 predictive indicators. 12 KPPFS with index weight are: work progress and smoothening (9.3%), change order management and work accuracy (9.1%), business relationship building (8.1%), adequacy of construction work procedure (8.6%), quality performance (8.0%), health and site safety adequacy (8.8%), Innovative contractor (8.0%), adequacy of construction site information (6.8%), compliance with contract plan/specification requirements (8.9%), creditworthiness and financial capability (8.3%), intra-agency relationship and responsiveness (7.0%) and resource management (9.2%). These results could be useful to project management body to evaluate performance of its contractor firm on site as well as the contractor itself to assess own performance and its subcontractors on-site.
