With the adoption of Level 3 BIM, cost estimation can be adopted through 5D. This is possible by linking the 3D model to an estimation library or database. 5D Estimation helps project stakeholders understand the project better, and collaborate efficiently. This preconstruction estimation data is used by designers, engineers, and other project team members to make informed decisions in terms of project planning, cost management, purchase, quality, etc.

The benefits of 5D BIM cost estimation have been highly recognized in the AEC industry. It is undoubtedly helping project owners and stakeholders leverage faster project delivery, minimize cost, enhance productivity, and project quality.

The integration of design and cost-estimation in preconstruction provides deeper analysis and project insight. The effective use and transference of data across the various project lifecycle creates a robust platform to avoid project rework, data loss, etc.

It also helps project stakeholders build better bidding proposals, efficiently handle project execution, and ensure positive project delivery.

transparency, mitigate errors & risks, etc. All this and more to ensure owners and project stakeholders can leverage better ROI.

Advantages of a fully connected BIM workflow based on 5D cost estimation
▪ Helps estimators work more efficiently
▪ Leverage unprecedented levels of information to enhance collaboration
▪ Enhance overall project performance through design & construction linking
▪ Better project visualization based on accurate estimation
▪ Augment quantification of modeled materials
▪ Find optimal accuracy and solution in calculating costs and planning
▪ The highly visual process makes it easier for estimators to understand new processes and technology
▪ Generate greater cost estimates at quick rates
▪ Create & deliver precise data for planning and field implementation

Along these lines, accurate estimation through high-end software helps create seamless workflows across all the project lifecycles.

How does 5D Cost Estimation Help?

▪ Build automated estimations based on access from 3D models – accuracy
eliminates errors and rework
▪ Increase in overall accuracy based on automated data processing
▪ Leverage historical cost data based on accurate takeoffs
▪ Connect data across various systems for project planning, cost management, etc.
▪ Cost management tools can be used to verify 5D estimation data based on
comparisons between budgeted data and the actual amount
▪ Gain greater insight into the project through accurate 5D cost estimation
▪ On-site personnel can leverage building strategies and gain insights through
real-time information on materials, costs, etc.

Understanding Design and Construction as an Integrated System
▪ It is important to identify a very strong relationship between design &
construction, it can be best viewed as an integrated system
▪ That said, the design creates a highly detailed description of a building, facility, infrastructure, etc based on models, plans, etc.
▪ Whereas, construction planning involves the identification of activities and resources to make these projects a reality
