| Abstract |
Domestic Korea construction industry experiences higher accident rate than other industries due to overtime and extra works resulted from inadequately planned short schedule. After identifying candidate drivers affecting construction schedule of an apartment project from intensive interviews with experts, a total of 117 field data was collected in order to develop a standard for determining whether or not a planned schedule for concrete structural frameworks is optimum. From correlation and multiple regression analyses with the data, four drivers, namely 'ratio of floor area to site', 'no. of floors', 'no. of ground floors', and 'no. of days needed for concrete curing', were identified. Furthermore, a two-way table using 'no. of ground floors' and 'no. of underground floors' has been developed for the determination of an optimum schedule. It was also found that the driver of 'no. of days needed for concrete curing' can be used as an adjustment factor for better judgement of the duration. The results will be in the great interests for those that are likely to check if planned or changed schedule is how optimum and to reduce risk of accident let by too much extra and overtime works. |
