Since the introduction of BIM Technology, it has become a significant trend for cost engineers. But what exactly does BIM bring to the role of a cost engineer? The BIM Architecture Training Network offers a brief analysis covering three key areas: methods, processes, and standards.
1) Working Methods
Cost engineers utilize the information embedded within the BIM models created by designers to prepare cost estimates. Initially, they must filter the data generated during the design phase to extract project details that meet the required precision for cost estimation at various project stages. This involves ensuring that the information provided by designers aligns closely with the data needed for accurate cost preparation.
2) Workflow
Cost engineers bear full accountability for the accuracy of cost outcomes. To ensure this, they need to engage early in the design process and collaborate with designers to define the information structure of project components. Without early involvement, cost engineers may spend excessive time verifying and adjusting BIM models supplied by designers later in the process.
3) Pricing Standards
Project costs are influenced not only by quantities and unit prices but also by factors such as construction methods, procedures, and site conditions. Currently, there is no universal standard for establishing BIM models that incorporate these constraints. Therefore, it is crucial to develop work standards tailored to specific projects and company practices. These may include component classification standards (such as building element classifications), list pricing standards, and decisions on whether to apply enterprise-specific or budget-based quotas for pricing.
From these three points, it is clear how BIM technology transforms the work of cost engineers. As for additional changes, I have yet to identify them and welcome further insights from others.
