Material costs typically represent a significant portion of engineering expenses, often making up around 70% of the total budget and up to 80% of direct costs.
As a result, controlling material costs is critical in managing overall engineering expenses. Material consumption refers to the total quantity of materials used throughout the construction process for a project. It comprises two components: net usage and material loss, expressed as material consumption = net usage + material loss.
Analyzing material consumption, especially planned usage, presents a significant challenge in construction management. Building Information Modeling (BIM) integrates detailed engineering information, such as design drawings, to create a virtual representation of the building. This model includes multidimensional data covering costs, schedules, materials, and equipment.
BIM enables component-level analysis, allowing for rapid and accurate calculation of engineering quantities. When combined with relevant quota or consumption analysis systems, it helps establish material plans and targets for various components, workflow stages, and time milestones.
With BIM technology, construction teams can overcome issues related to limited material requisition. Using historical data from similar projects stored in BIM, auditors can quickly simulate and calculate the consumption of any work segment through multidimensional modeling. This process verifies the accuracy of material usage on submitted requisition forms before finalizing distribution.
In summary, BIM empowers construction units to optimize material procurement planning, inventory management, and consumption control with precision. It supports effective oversight of material planning, purchasing, inbound and outbound logistics, ultimately fulfilling the goal of limited and efficient material requisition.
