ABSTRACT

The accident rate in the Korean construction industry is much higher compared to the one in other industries. One of the main reasons for this problem is the health and safety management cost (HSC) estimation method which does not reflect the project features at construction sites. In Korea, health and safety management cost is estimated by applying a legally designated ratio in proportion to construction cost without reflecting construction features, such as the building’s shape, number of floors, and construction period. However, such a method does not fulfill the cost for the gradually strengthening safety management of high-rise residential buildings. Therefore, the objective of this paper is to develop a cost assessment model for sustainable health and safety management of high-rise residential buildings. For this purpose, actual data of 23 completed projects were collected and analyzed to identify problems and influence factors of HSC assessment and to establish a regression model. By applying the model established for five new sites as a case, its validation was verified. The results of this study will be utilized as reference data for the HSC estimation method and its relevant policy establishment.

摘要

与其他行业相比，韩国建筑业的事故率要高得多。造成这一问题的主要原因之一是健康和安全管理成本 (HSC) 估算方法不能反映建筑工地的项目特征。在韩国，健康和安全管理成本是通过应用法律规定的与建筑成本成比例的比例来估算的，而不反映建筑特征，例如建筑物的形状、层数和施工期。然而，这种方法并不能满足逐步加强高层住宅建筑安全管理的成本。因此，本文的目的是为高层住宅建筑的可持续健康与安全管理开发成本评估模型。以此目的，收集和分析23个已完成项目的实际数据，找出HSC评估的问题和影响因素，建立回归模型。以五个新站点建立的模型为例，验证了其有效性。本研究结果将作为HSC估计方法及其相关政策制定的参考数据。
