5D BIM visualization helps improve budget analysis and cost estimates. Conventional estimation techniques that depend on 2D drawings show potential errors, ambiguities and inefficiencies. A 3D BIM model live-linked to actual material quantities of construction objects, equipment and other resources helps mitigate inconsistencies in project cost estimations. 5D helps project stakeholders improve project budgets, delivers cost-loaded schedules and enables in-depth and accurate forecasts for agile comparability. With parametric modeling and higher process flexibility, cost-adjustments can be leveraged in real-time based on any design changes. The core value of 5D cost estimation enables General Contractors to enhance value-engineering judgments for project owners.
