Abstract |
With full-time on-site supervision throughout the entire duration fo dismantlement, a method has been introduced to allow the use of the cost-plus-fixed-fee method in addition to the previously used percentage-of-construction-cost method for calculating supervision fees. Unlike the percentage-of-construction-cost method, which applies rate depending on cost of dismantlement works, the cost-plus-fixed-fee method permits variations in supervision fees through consultations among stakeholders, with such variations reflecting building scale, dismantlement plan, etc.
Therefore, this study perform the correlation analysis between supervision fees and variables by utilizing dismantlement supervision contract data from Seoul over the past four years. Based on these main variables with high correlation to supervision fees, a simplified estimation formula is proposed to statistically evaluate appropriate supervision fee levels, and its predictive performance is evaluated.
