Quantity Surveying and Cost Engineering for Complex Building Projects

Quantity Surveying represents B&B Progetti SB’s distinctive competence, founded on a clear operating principle: intervening at the early stages of the project, when economic decisions can still determine the final outcome. Traditional practice, which relegates cost estimation to completed design, reduces economic control to an ex-post verification. Early involvement of cost management expertise allows the economic primacy of the project to be preserved, steering design choices according to financial sustainability.

The Value of Cost Engineering: Method and Tools

The method is founded on predictive models and quantitative analyses across the full economic-financial cycle: parametric estimates and bills of quantities, cash flow analysis, profitability assessment, cost control throughout the lifecycle. Integration with the BIM environment enables accurate, real-time Quantity Take-Off, replacing the approximations inherent in traditional approaches.

The economic management of a complex project also requires the capacity to identify and anticipate risk: sensitivity analyses, variance assessments and investment optimisation are integral to every commission, supporting general contractors, property developers and funds from the initial decision-making phase through to project completion.
