3D modeling of all disciplines including architecture, structure, MEP, interior design, landscape, is the first step towards implementation of BIM in project. With in the process of BIM, 3D modeling is an integrated job. This means that other designers in different disciplines work in an integrated environment and produce a single integrated model. So they can be informed from the last changes in other disciplines designs and make necessary changes for their plan accordingly. This unified model acts as the key tool for being linked to a database which contains properties, proportions, costs, and time schedules of the project. 3D modeling of a project leads to a better understanding of design for all stakeholders, due to the visualization. On the other hand, this process will deliver the designs with more quality.

3D Modeling of All DisciplineThe first step towards Implementation of BIM in project is 3D modeling of all dicsiplines including architecture, structure, mechanical, electrical, interior design, and landscape in an integrated environment, which leads to product a single integrated model.
These models contain sets of objects which have common properties. The term "family" refers to any group of elements that share common properties. These families are modeled according to the equipment in each discipline. Project families modeling is part of the process of modeling.
Virtual Reality (VR) Design ReviewThe BIM model is used to validate design in accordance with the requirements of the employer and other non-technical stakeholders. BIM helps stakeholders maintain a common understanding, regardless of the amount of their knowledge. In this process and in meetings, stakeholders view a 3D model and provide their feedbacks to validate multiple design aspects. These aspects include evaluating meeting the program, previewing space aesthetics and layout in a virtual environment, and setting criteria such as layout, sightlines, lighting, security, ergonomics, acoustics, textures and colors, etc.
QTO & Cost EstimationAnother important BIM use is cost estimation with high accuracy and quality at the fastest time possible. Due to the object-oriented BIM model, geometric information and dimensions of all elements are available. Therefore, using special software can easily measure any part or the whole project in just a few moments. This BIM feature allows designers to observe quantity take-off and estimation and the cost effect of design changes over time with high accuracy and relatively low time compared to traditional QTO and estimation methods.
Benefits of Clash Detection
- Coordination of design in all disciplines
- Lessrework in construction phase and as a resultless construction cost and time
- Accurate as-built drawings
