1. Planning and Design Phase
BIM technology plays a crucial role in the planning and design phase by reducing errors in feasibility studies and improving site investigation accuracy. However, the precision of BIM often comes at a higher cost—the more accurate the technology, the greater the expense. Some argue that traditional decision-making methods are more cost-effective. Yet, while the benefits of BIM at this early stage may not be immediately apparent, making well-informed decisions guides the entire project toward success. Effective decision-making at this phase ensures smoother subsequent activities and significant cost savings throughout the project lifecycle. Therefore, although BIM’s advantages during decision-making might seem limited, they lay the foundation for substantial benefits during construction and operation.
The same principle applies to cost control during the design phase. Real estate developers often require quota-based designs, but projects designed under traditional methods frequently fall short. This is because conventional design software cannot independently detect cost-related data, forcing designers to rely on approximate data. As a result, these designs often either fail to meet aesthetic standards or compromise structural stability.
By contrast, BIM technology transforms the design phase. Using BIM software for quota design inherently builds a cost database. As the model develops, a cost budget is established. Designers can access or create cost lists for specific components at any time, ensuring quota-based designs better meet the expectations of homeowners and buyers.
2. Bidding Stage
During the bidding phase, costs are estimated by calculating the quantities of work based on drawings, which then inform bid pricing. Traditionally, the most challenging tasks for cost estimators involve measuring quantities and inputting data into models. This repetitive input and output not only wastes manpower but also extends project timelines. BIM technology streamlines this process by allowing rapid model import and shortening the preparation time of bills of quantities. It also enables bidders to quickly identify and calculate discrepancies in quotations. Essentially, BIM enhances both modeling and bill of quantities preparation, improving bidding efficiency.
3. Construction Phase
The construction phase is typically the longest stage in real estate development and is highly dynamic. As construction advances, more procedures require coordination, increasing complexity. Developers place great emphasis on this phase and standardize construction activities through various methods. While traditional techniques exist to regulate and optimize construction, none can monitor progress in real time. BIM technology revolutionizes cost control during construction by enabling the creation of detailed models that simulate the building process ahead of time. This simulation anticipates potential issues, allowing designers to adjust plans proactively. Multiple simulations help avoid construction problems and reduce unnecessary costs.
4. Completion and Settlement Stage
BIM-based cost management during project completion provides a comprehensive overview of all construction expenses. By this stage, the BIM model is nearly complete, and with ongoing updates to contracts, process changes, and payments, the information database serves as a reliable reference for final settlement. Traditionally, final settlements were challenging due to financial complexities and frequent disputes. BIM technology brings transparency to capital expenditure, material costs, and claims, minimizing conflicts and accelerating the settlement process.
