Project cost management plays a crucial role in construction, requiring systematic and comprehensive compilation of various engineering quantity data, such as project progress payments and final settlements, to effectively control construction costs. However, calculations show that the actual time spent on quantity surveying often exceeds half of the entire construction timeline. Whether performed manually or using software, quantity surveying demands significant manpower and resources. Despite this effort, ensuring the accuracy and reliability of the data remains challenging.
When it comes to preparing design budgets, BIM models contain extensive project components and detailed part information, along with powerful calculation capabilities. This enables rapid computation of the data needed for design budgeting, delivering relatively reliable results. As a result, BIM effectively addresses the tedious data compilation involved in traditional drawing-based quantity surveying and reduces the complexity of design tasks. Additionally, BIM models can adapt to various requirements and calculate according to different standards.
In the bidding process, traditional methods require the construction team and consulting parties to manually calculate quantities and prices based on drawings from the design team. This approach is time-consuming, labor-intensive, and prone to errors and unnecessary losses. With BIM software, design teams can embed all drawing information directly into the model. Construction teams can then extract the required quantity and pricing data directly from the model, significantly reducing the workload of technical staff, improving calculation accuracy, simplifying bill preparation, shortening bidding preparation time, and providing strong technical support for an early project start.
Furthermore, during bid evaluation, bidding units can quickly review and verify the BIM models provided by bidders. This process helps prevent calculation errors caused by limited time and effectively mitigates risks.
