Abstract
With the BIM applications on fast-track, it is being used for new construction and recently being utilized for renovation, retrofitting, and repairing purposes. Although many studies have been conducted to identify BIM capabilities in renovation projects, the application of 4D BIM for both the demolition and the construction phases of renovation projects is still underdeveloped. This paper presents a guideline to apply 4D BIM for complicated renovation projects that include demolition and construction phases. The paper represents a step-by-step process from the extraction of information from a 2D model and converting it into a 4D model. The proposed guideline will help CAD users to apply 4D BIM for complicated renovation model. A real case application is analyzed to demonstrate the potential of the presented guideline. The research results show that the proposed guideline could assist in construction management by finding out inappropriate sequences in schedule, conducting evaluation of issues related to constructability, and identifying disagreements in time and space. The proposed guideline could help identify errors in construction scheduling, which have the potential to reduce project cost and duration.

This paper provides step-by-step guidance for CAD users to apply 4D Building Information Modeling (BIM) for renovation projects
Shiue et al (2019) argued that planners in construction usually interpret 2D or 3D drawings and specifications to generate sequential relationships of activities in the schedule. They stated that the project stakeholders, including contractor, client, and designer have to generate the physical building by mental association of the schedule information, which represents the integration of time and space. 4D model facilitates the generation of a 4D movie, representing the relationship between 3D model and schedule information, and removes the cumbersome mental visualization task (Shiue et al, 2019)
Summary
Renovation is a common way of maintaining buildings in order to serve their users. The main feature that influences the complexity of renovation projects is the concurrent use of a building by both workers and users. It is usually not possible to close a whole building to carry out a single-phase renovation project (Bakri et al, 2017). There are possibly conflicting activities between the construction crew and occupants. To address this problem, a renovation project is generally carried out in a number of segments in different time periods or locations.
