The cost management approach for construction projects in our country has continuously evolved, along with improvements in pricing methods. BIM technology now enables the development of software to accurately calculate the engineering quantities for projects. When calculating costs for pipeline installation engineering, it is essential not only to quantify the specific engineering volumes but also to align these quantities with the corresponding quota sub-items. To address this challenge, a differential definition method can be applied based on the attributes of different components during the construction of the project model for pipeline installation. This allows the software to classify components by their attributes during the counting process, significantly enhancing the efficiency of matching engineering quantities with fixed prices.
(1) Enhancing the Accuracy of Engineering Quantity Calculation
Before the widespread adoption of computer technology in construction, manual methods were used to collect various basic data, including project quantities during pipeline installation. Cost professionals calculated these quantities based on design drawings and prepared budget reports following specific cost rules derived from budget quotas and market conditions. However, calculating engineering quantities is a complex and tedious task that involves many detailed steps. Manual data collection is time-consuming and labor-intensive, and even experienced cost personnel are prone to errors and omissions, resulting in low efficiency.
With the ongoing development and application of computer technology in construction, software such as Xing’an Deli has been introduced to assist in pricing operations. Yet, the calculation of engineering quantities still largely depends on manual processes, keeping the workload high for cost personnel. As large-scale construction projects become increasingly complex, manual methods can no longer keep pace with the demands of the industry. In response, 3D computing software based on BIM technology has emerged, enabling rapid model construction tailored to project requirements. Components can be distinguished by their attributes, and geometric operations such as entity deduction can be applied, greatly simplifying the statistical process. Furthermore, importing engineering quantity files into cost management software allows seamless correlation between engineering data and cost databases, facilitating report generation. This approach not only saves time and reduces complexity but also improves accuracy and significantly boosts efficiency.
(2) Optimizing Resource Planning
Prior to BIM technology, engineers relied on personal experience to estimate workload during pipeline installation, which led to a highly subjective allocation of equipment, materials, and labor. The BIM 5D model integrates cost and schedule data into a single platform, providing real-time information for cost management throughout construction. This enables precise quantitative cost control, enhances management efficiency, and supports refined project oversight. As a result, funding, labor, material, and machinery plans can be arranged more rationally. Real-time monitoring helps prevent budget overruns and improves the overall allocation of resources.
(3) Accumulating and Sharing Historical Data
Currently, pipeline installation project cost data is typically stored in paper files or electronic formats such as Word documents and Excel spreadsheets. These files tend to be isolated regardless of format, making it difficult to quickly locate specific data amid the large volumes generated during pipeline installation. BIM technology addresses this by integrating data into a centralized, shareable database. This system allows quick access and timely updates, enabling all project participants to share relevant information and ensuring that the database remains current and consistent.
