Abstract
Despite being a profitable sector with a significant share in national GDPs, the construction industry has numerous adverse effects on the environment and society. Moreover, most of the conventional delivery methods of construction projects suffer from a short-term cost vision and plan, not sufficiently emphasizing the Operation and Maintenance costs, which comprise nearly 60% of construction projects Life Cycle Costs. Therefore, a collaborative framework for including all three pillars of sustainability (economic, social, and environmental sustainability) in an integral and long-term fashion would contribute significantly to the success and resilience of construction projects.
This research proposes a Building Information Modelling (BIM)-based LCC estimation framework to facilitate objective and optimal decision making throughout the entire life span of the projects and by the effective collaboration of key stakeholders. BIM offers a great opportunity for systematically storing, visualizing, retrieving, and analyzing technical and financial information in a phase-based manner. Therefore, this research aims to design an integrated and transparent BIM-based framework applicable to the majority of Tehran's construction firms. The framework's validation is done by a case study approach on a residential project in Tehran to explain the workflow of the proposed framework more clearly. Implementing this framework in Tehran's construction sector will positively impact the success rate of projects and will increase their lifespan and productivity compared to the current status that residential buildings barely survive more than 50 years.
