Abstract

In the cost analysis of most studies, the focus has just been on a micro-scale (per unit cost analysis) and few have considered a project-scale analysis. This study aims to fill the gap by performing a project scale cost analysis considering innovative CHBs with propylene(PP) pellets and low-density polyethylene (LDPE) pellets as partial replacement for sand. The project considered was a standard four-story school building ? the structural plans of which are provided by the Department of Public Works and Highways (DPWH). Using the trial version of ETABS 2013, the effect of using CHBs with plastic pellets was determined by comparing the reduction of reinforcement (and therefore, cost) due to their substitution to the conventional CHBs. The studies of Lasco (2013) and Dolores (2014) were used as a benchmark, i.e., the percent increase in cost from their study was used to determine the change in cost due to the substitution of CHBs with PP and LDPE pellets, respectively. Results showed that the reduction in required reinforcement is insignificant, which is 0.79% and 1.08% of the total weight of the beams? reinforcement. Thus, the total project cost increased by 2.76% and 6.33% by using CHBs with PP and LDPE pellets, respectively. This increase in cost could be attributed to the higher cost of plastic pellets used.
