Goal: Engineering Analysis


Phase(s):

Schematic Design, Design Development

Objective:

[_] Design optimized engineering systems and enhance building performance with using BIM analysis tools
[_] Accelerate design decisions making by conducting faster engineering analyses and communicating the results to the design team
[_] Improve collaboration between designers and consultants
[_] Perform more effective value engineering earlier in the design process

Description:

A process in which intelligent modeling software uses the BIM model to determine the most effective engineering method based on design specifications. Development of this information is the base for what is passed on to the owner and/or operator for use in the building's systems (i.e. energy analysis, structural analysis, emergency evacuation planning, etc.). Core of BIM is the digital database where each object, space or characteristic are defined and easily accessible. BIM as a virtual representation of a facility with its digital database enables various qualitative and quantitative engineering analysis. These analysis and performance simulations can significantly improve the design of the facility and its energy consumption during its lifecycle in the future.
Audit and analysis tools play key role in analyzing building information models or adding to the richness of information in a model. They usually focus on one analysis like energy modeling, code compliance checking and clash detection.

Potential Benefits:

[_] Automating analysis and saving time and cost
[_] Analysis tools are less costly than BIM authoring tools, easier to learn and implement and less disruptive to established workflow
[_] Improve specialized expertize and services offered by the design firm
[_] Achieve optimum, energy-efficient design solution by applying various rigorous analyses
[_] Faster return on investment with applying audit and analysis tools for engineering analyses
[_] Improve the quality and reduce the cycle time of the design analyses

Levels of Detail Considerations:

  • Depending on the type of the engineering analysis done
  • The more detailed the model, the more accurate the analysis in predicting actual building performance
