Assessment of BIM in construction management: the impact of WBS, QTO, cost estimation and time analysis on decision making policy for optimization of energy efficiency

In Europe, the argument over the relevance of global building sustainability (covering energy, environmental, social, economic, and political issues) is becoming increasingly relevant. In this context, the restoration of existing buildings, particularly those with large volumes and low energy performance, receives considerable attention, however the age of building is another involved factor that must be considered. On the other hand, over the previous few decades, the term of “Building Information Modeling,” or BIM, has evolved from a term with a few early adopters to the heart of AEC technology, which encompasses all aspects of building design, construction, and operation. Almost every major design, engineering, and construction firm in the world has switched to BIM from their prior, drawing-based CAD technology. In a more precise sense, BIM in the construction management industry gives not just clients but also project managers the ability to model and estimate crucial project characteristics such as time and cost before they are realized. The major purpose of this project is to represent a decision-making route based on two most important parameter in project management which are cost and time, for reconstructing or renovating an existing building using BIM software in order to achieve a satisfactory energy grade in the building. The cost and time parameters will be used to evaluate this project, which are also influenced by Take Off Quantity (TOQ) and Work Breakdown Structure (WBS). This project makes use of a variety of BIM applications including, 3d modeling for modeling, Quantity take off software for TOQ, Excel and management platform for cost and time estimation and Energy simulation software.
