KAJIAN PERBANDINGAN PENGARUH PENGGUNAAN DINDING PRECAST DENGAN DINDING KONVENSIONAL PADA PROYEK CORDOVA SEMARANG

Abstract

Innovation in the world of construction is something that is indispensable, one of the innovations in the construction sector is precast. The use of precast is expected to be able to reduce project costs to accelerate the duration of work. But in fact, the products of innovation in the world of construction have not been fully able to have a positive impact, both in terms of cost, quality, time, waste, on project development. Products of innovation are usually not necessarily in accordance with the wishes and needs of the customer. The purpose of this research is to analyze the comparison of products in terms of time, cost, quality, waste, and in terms of K3L between projects using precast walls and projects using the lightweight brick wall method. This research was conducted by (1) conducting a project simulation if the project did not use precast, (2) comparing a real project with a simulation project in terms of cost, quality, time, waste, and K3L. The use of precast in the Cordova project when compared to a simulation project that uses lightweight bricks results in (1) in terms of time saving 36,84 % on the simulation results project (2) in terms of costs can be reduced by Rp. 101.488.543,99 (3) in terms of quality precast material has The quality is better than the lightweight bricks (4) in terms of waste, in the simulation result project it creates more waste (5) in terms of K3L, the use of precast is more environmentally friendly than the simulation results project.
