“…The benefits of BIM classified according to three different applications in the construction industry. The first is Building Design, BIM, provides a comprehensive approach for evaluating design options [34], utilizing BIM in the early stages of the project life cycle for understanding the scope of work [35]. The second is building construction, BIM, allows all parties from different disciplines to updating and tracking the project documentation by utilizing a traceable and effective methodology [36].…”

Construction projects face delays and disturbances that could be caused by one of the contracting parties, both of them, or beyond their control. Proving the delay needs a significant effort to introduce all details, documents, and records which explain the causes of the delays. The contractor needs to submit a claim, whether it is extension of time (EOT) claim or any claim with an adequate definition, causation, liabilities, analysis of delays to get an extension of timerelated to the risk event. Claims preparation processes need to be collected and documented daily throughout the project phases, especially during construction phases. Lean Construction, with its common technique, the last planner system (LPS), and building information modeling (BIM) have significant synergies and can bring benefits when implemented together to support the preparation of the extension of time (EOT) claim. Building information modeling used as a digital platform to facilitate communication between the project team, improve project performance, and implement the last planner system (LPS) phases effectively. (LPS) is enhancing the coordination within the project team.

“…Researchers have mentioned that the differences in the extraction quantity are due to the modeling and detail composition of the objects [13] (Monteiro & Poças Martins, 2013), and concern that variations in the amounts extracted from BIM could affect the accuracy of estimating construction costs (BoQ) From these problems it can be stated that this research is the first to be conducted regarding the increase in cost performance based on BIM Quantity Take-Off on hospital building structures. Poor knowledge about the benefits of BIM, resistance to change, poor training, and education all these are important barriers facing BIM use [14]. One of the key benefits of BIM is the accurate geometrical representation of building within an integrated information environment [15].…”

Indonesia's population is ranked 4th in the world after India and the United States, as well as the global Covid-19 pandemic, Indonesia is also recorded with the most cases of infections and deaths due to Covid-19 in ASEAN, therefore Hospitals in Indonesia has not been able to represent the need for beds and health services. Therefore, the hospital building construction project has become a driven demand for the fulfillment of health services for the Indonesian population. Estimation is one of the causes of the cost overrun. Implementation of Building Information Modeling Quantity take-off (BIM QTO) in hospital structural work can be done if the cost breakdown is ≤ 24%. Statistical analysis by using the Relative Importance Index (RII) has a result in 10 rankings of factors that influence the implementation of BIM QTO, namely drawing, completeness Bill of Quantity (BoQ), TOR & specifications, cost reduction, preparation of activities in the work breakdown structure, cost breakdown, 3D modeling details, Data Interoperability, Quantity Take Off, Subcont & Supplier pricing, and cost database. Study cases with the implementation of BIM QTO on hospital building structures work cost efficiency up to 6.18%.

“…Therefore, codifying these practices enables them to be teachable, repeatable, and scalable. This is analogous to how McCuen (2015) identified the AACE uses of Stochastic and Deterministic methods to define quantity takeoff strategies at various stages of design.…”

The preconstruction field has struggled to adopt model-based practices and often lags behind in implementing similar BIM-based workflows in the construction industry. Model-based estimating practices provide a mechanism to increase efficiency and improve the overall preconstruction process. However, even as rapid growth in technology continues, current barriers to adoption persist, and the industry is challenged to educate and train the workforce to use these technologies effectively. A simplified model-based estimating framework must be identified and standardized to solve these barriers to adoption. This paper proposes a framework supporting a software-agnostic, standardized BIM-based workflow for preconstruction called the Integrated Estimating workflow, which relies upon five categories: 1) Intentional Model Authoring, 2) Qualitative and Quantitative Data, 3) Integration of Cost, 4) An Estimating Standard, and 5) Application of Automation or Augmentation to either parts of or the whole process. The significance of this framework is to identify an uncomplicated, but standardized model-based estimating workflow, and to create an identifiable distinction between this workflow and others commonly referred to as model-based estimating workflows.
