Abstract
Precast construction is a construction technology which uses prefabricated elements. As compared to traditional on-site construction, superior concrete quality can be achieved due to high tolerances in factory conditions and most importantly, projects can be completed within a shorter period. Since precast units are known to be expensive, this study focused on the integration of past undergraduate studies regarding the use of rice husk ash as cement substitute into a large-scale project to further reduce its total construction cost. A condominium in Ermita, Manila with nine floors and a roof deck was considered. Precast interior walls were modified using the said innovative material based on the studies of Quiring (2014) and Villacrusis (2014). Cost analysis was then performed by comparing the original estimates and the constructed bill of quantities. For the construction of precast interior walls, cost reduction by 2.46% was observed due to changes in material and transportation cost. In conclusion, the use of rice husk ash as cement substitute is a cost-effective alternative in precast construction.
