Time Cost Quality Trade-Off in Repetitive Construction Project for Sustainable Construction Project

The concept of sustainability is about the relationships among people, the planet, and profit. Nowadays, it has been spread to many areas, including construction projects. Sustainability in construction projects has been so important in the present time. It is commonly pointed to the environment and construction materials. Nevertheless, it is also important in construction management which addresses sustainable project scheduling. Sustainable project scheduling will help to deliver the project under the deadlines, within the available budget, and also ensuring about the quality of the works. This study presents the trade-off among time, cost, and quality in the construction project to provide the decision-maker some alternative solutions in the planning phase to conduct a sustainable construction project. Multi-objective optimisation using Symbiotic Organism Search (SOS) algorithm is done to find the best solutions to the problem under investigation. Then, fuzzy logic approach is utilised to model the diverse environment and uncertainty in the construction project. A case study in repetitive construction project is analysed to see the capability of the model to work in time cost quality trade-off to reach into a sustainable construction project.
