ABSTRACT

A Study on Improvement of Ways for Reducing Construction Duration in Building Construction -focusing on apartments in Gwangju City-

Building construction has multiple complex processes related to each other, and sometimes, it can happen that even though a careful review is conducted when calculating the construction duration, unexpected situations and certain factors affecting construction duration frequently take place to make it impossible to finish the construction on time. When construction delay occurs, the ordering party is usually at a more advantageous position in terms of the contract than the constructing party, who is forced to come up with a feasible solution. When a construction experiences delay, the constructer usually tries to reduce the construction duration even using unreasonable and excessive work loads because the constructer has to face a serious additional cost incurrence such as paying a higher maintenance fee, higher interest rate, and additional cost for rush work in addition to the imposition of postponement fees and has to deal with the claim from subcontracting dealers. This phenomenon is a widespread problem in building construction industry.

Therefore, this study aims to propose improvement plans to efficiently manage the reduction of construction duration against any possible delays and conducted a survey investigation by visiting the construction sites of the apartment houses in Gwangju City to identify the process and construction duration management status. The study analyzed the problems and came up with possible improvement plans for reducing construction duration, and the following conclusions were reached.

First, the preliminary investigation of the construction site and understanding of the drawing must be carried out and the proper construction duration must be calculated considering the work distribution. Also, the ordering party and the constructing party must meet together and fully discuss and review the conditions of the construction site to calculate the proper construction duration.

Second, using the weekly and monthly process table, the construction progress must be checked, and using these checkpoints, the schedule must be reviewed, and the revised process table due to construction delays and the detailed process table must be written out such that the work team can easily understand them and identify the current status of the construction.

Third, through professional educational institutions and college education, professional work force must be raised, and the database must be constructed to develop an electronic operation system for reducing construction duration which can apply the exiting data to another construction site of the similar type.

Fourth, by introducing the advanced way for management, the proper way of ordering that fits the conditions in Korea must be selected, and to reduce the increase of the construction cost, it is necessary to introduce the advanced management technology that can manage the product quality, process, etc in an organic and integrated way.
