5D BIM
Building Information Modeling (BIM) generates a complete digital model of the building that can produce exact bill of material and cost estimate along with coordinated drawings and details. A conceptual building information model can provide a quick feedback on several design assumptions as the model contains components with historical cost data, productivity data and other estimating data. In BIM based estimating & takeoff system the design model is linked with estimating process and the quantity takeoff along with overall estimating process is greatly enhanced. The faster feedback on proposed design changes can be easily achieved
The 3D model provides highly accurate quantities for estimating purposes. As the design develops, the estimate is automatically updated, enabling significantly faster decision making on cost issues compared with traditional take-off methods. The quantities can easily be visually audited in the model and comparisons made between estimate versions. BIM based estimating process can also cut down overall contingency and dependability and cause huge savings in profit.
•Accurate, faster and Up to date. Quantities are extracted directly from the Virtual Construction model. Can be exported in Excel and in any specific formats.
•Highly accurate estimates in less time. Faster incorporation of Changes/ Updates
•Reduce inaccuracies and risks. Communicate the relationships between quantities, costs, and locations. Procurement planning and RA Bill Verification Support.

One of the advantages of working with 5D BIM models is being able to show the Owner different what-if scenarios. What if we added more retail floors, more levels to the parking lot, what if we used Green materials in place of conventional materials? 3DPrime assist Owner/Contractors/PMC companies by delivering a report comparing two versions of the cost plan using the parameters setting.
As the building design matures and construction details are accurately modeled, precise quantity takeoffs can be extracted from the BIM model to compute very detailed cost estimates that factor in the planned construction process and consider the labor, materials, equipment, and subcontractor costs for all building elements. As the level of detail for each element in the model increases, the level of costing detail can grow with it. So, as the design evolves and more details are specified, our cost estimates grow more and more precise.
Having this cost feedback available at every state of design enables project teams to:
•Compare cost plans to the original project budget at any point in time. Stakeholders can easily see what has changed and decide when and to adjust scope as necessary.
•Understand and focus on design decisions that have the largest impact on the project cost.
•Evaluate the cost impact of proposed design enhancements and what-if scenarios.
•Compare the impact of using sustainable design strategies in terms of installation
The combination of BIM and integrated software solutions can enable delivery of benefits of up to 30% across the construction supply chain. Construction clients need to be convinced that the industry can deliver these savings and are starting to specify BIM deliverables. Delivering the benefits requires a number of key success factors including teamwork, enthusiasm, adaptability, standards and of course, the integrated solution itself. Solutions are applicable across the supply chain from owners to contractors.
