Reliable cost estimation is paramount for successful projects, while in Libya, conventional methods are still inefficient, manual, and subject to human error. It examines integrating Building Information Modeling (BIM) with the Libyan Price Guidelines (LPG) to automate and improve the accuracy of cost estimation for building projects. A Revit-based BIM model was created and integrated with LPG data to generate real-time cost calculations and computerized quantity take-offs (QTO) to counter the inefficiencies in the existing manual system. A standardized questionnaire was administered among professionals in the Libyan construction sector and elicited 41 valid responses. Survey data analysis indicated very low BIM adoption and high usage of traditional estimating tools like spreadsheets. The suggested BIM–LPG approach was successful in mapping cost items with model elements in 74% of the cases in different categories in the construction field. Expert verification indicated the feasibility, practicability, and applicability of the approach, especially for enhanced estimation accuracy and elimination of routine manual activities. This work adds an automated cost estimation model specifically adapted for Libya’s construction scenario. It brings tangible value to quantity surveyors, cost estimators, project managers, and decision-makers through the improvement in cost control, the reduction of estimation inaccuracies, and real-time updates as project designs change. In the process, the work facilitates an overall movement toward the use of BIM in Libya, bringing local practices onto par with international standards for digitalized construction management.
