#32 - BIM Uses - 1

The nature of BIM Technology allows different stakeholders to use the BIM in multiple ways depending on their specific needs. As a project moves from phase to phase, the information contained within the BIM shall evolve in a progressive manner.

The following list of BIM uses is the most common application of BIM. BIM uses shall be aligned and considered with project goals and selected based on added value.

EXISTING CONDITIONS MODELING:

It is a process in which a project team develops a 3D model of the existing conditions of a facility. This model can be developed in multiple ways depending on what is desired and what is most efficient. Once the model is developed, it can be queried for information, whether it is for new construction or renovation project.

The value of Existing Conditions Modeling is:

• Document existing buildings for historical use.

• Provide documentation for future uses

• Enhance efficiency and accuracy of existing conditions documentation

• Provide location information

• Aids in future modeling and 3D design coordination

• Use for Visualization purposes

SITE ANALYSIS:

A process in which BIM and GIS tools are used to evaluate properties in a given area to determine the most optimal site location for a future project. The site data collected is used to first select the site and then position the building based on other criteria.

The value of site analysis is:

• Use calculated decision-making to determine if potential sites meet the required criteria according to the project requirements, technical factors, and financial factors.

• Increase energy efficiency

• Minimize risk of hazardous material

• Maximize return on investment

ENGINEERING ANALYSIS:

A process in which intelligent modeling software uses BIM to determine the most effective engineering method based on design specifications. The development of this information is the basis for what will be passed on to the owner and/or operator for use in the building's systems. These analysis tools and performance simulations can significantly improve the design of the facility and its energy consumption during its lifecycle in the future.

The value of Engineering Analysis is:

• Achieve optimum, energy-efficient design solutions by applying various rigorous analyses

• Faster return on investment by applying audit and analysis tools for engineering analyses

• Improve the quality and reduce the cycle time of the design analyses

PROGRAMMING

A process in which a spatial program is used to efficiently and accurately assess design performance in regard to spatial requirements. The developed BIM allows the project team to analyze space and understand the complexity of space standards and regulations. Critical decisions are made in this phase of design and bring the most value to the project when needs and options are discussed with the client and the best approach is analyzed.

The value of Programming is:

• Efficient and accurate assessment of design performance in regard to spatial requirements by the owner

DESIGN AUTHORING

A process in which 3D software is used to develop a Building Information Model based on criteria that is important to the development of the building's design. Design authoring tools are the first step toward BIM and the key is connecting the 3D model with a powerful database of properties, quantities, means and methods, costs, and schedules.

The value of Design Authoring is:

• Transparency of design for all stakeholders

• Better control and quality control of design, cost, and schedule

• Powerful design visualization

• A true collaboration between project stakeholders and BIM users

• Improved quality control and assurance

SUSTAINABILTIY (LEED) EVALUATION

A process in which a project is evaluated based on LEED or other sustainable criteria. This can refer to materials, performance, or a process. Sustainability Evaluations can be applied across all four phases of a construction project, Planning, Design, Construction, and Operation. Sustainability evaluation is most effective when it is done in the planning and design stages and then applied in the construction and operations phases. Model all sustainable aspects of a project throughout its lifecycle in order to obtain the desired LEED certification in the most efficient manner by condensing design analyses into a single database.

The value of Sustainability Evaluation is:

• Accelerate design review and LEED certification process with efficient use of a single database with all the sustainable features present and archived

• Improved communication between project participants in order to achieve LEED credits and decreased redesign efforts as a result

• Align scheduling and material quantities tracking for more efficient material use and better cash flow analysis

• Optimize building performance by tracking energy use, indoor air quality, and space planning for the adherence to LEED standards leading to integrated facility management using a BIM model
