A- The information created by the process
· A 3D Construction Model of the entire site and building, including all MEP and FP systems.
· A 4D Model showing the construction sequence derived from the project schedule.
· A 5D Model that adds the costs and actual, to create a model and schedule linked to Earned Value Analysis.
· A Constructability Report detailing all coordination issues and missing information.
· Coordination Resolution of MEP/FP systems including hangers and seismic restraints.
· Layout support and in-place construction verification using model data in total stations.
· Presentation Materials: Fly-through animation and renderings.
· Model-driven, location-based quantity take-off. Complete estimates based on the contractor’s means, methods, and pricing.
· Flowline Schedule: A location-based schedule optimized for continuous workflow.
· A Production Control system provides improved forecasting & crew management.
. Constructability Analysis:
The 5D modeling process highlights potential problems in the project’s design and identifies missing information in the construction documents. The list of problems is provided to the project team as a discrepancy report. Elimination of these errors has been proven to reduce project cost by 3%-5%.
The 5D model is the ideal tool to communicate project status and issues to all project stakeholders. Usage of the model for communication purposes ranges from high level meetings with project stakeholders, to detailed planning meetings with individual subcontractors.
· Model-based Quantity Take Off: - New Basis for cost estimation.
The 5D model produces highly accurate quantities, which are combined with a company database to create the project estimate. Update time is dramatically reduced, and the project team can communicate the variances to the budget or previous estimates. DPM experts can leverage this process by providing estimating assistance.
· Project Planning and Control:
The 5D Model can be combined with Control Office to provide a best-in-class solution for analyzing a project’s schedule and controlling site production. This can optimizes task production rates, reduces starts and stops, and allows project durations to be reduced by an average of 10%.
B - Advantages:
We don't believe in technology for technology's sake. We think beyond the technology, and instead focus on the value that it can bring to your project. In the hands of our capable team members, technology becomes a valuable decision-making tool on your project, allowing us to save time, save money and build a higher quality project. Building information modeling is once such technological advancement that has benefits at virtually every stage of a project.
BIM – building information modeling – is a coordinated set of processes, supported by technology, that add value by creating, managing and sharing the properties of an asset throughout its lifecycle. BIM incorporates data – physical, commercial, environmental, and operational – on every element of a development’s design.
1. Better outcomes through collaboration
All project partners – different design disciplines, the customer, contractor, specialists and suppliers – use a single, shared 3D model, cultivating collaborative working relationships. This ensures everyone is focused on achieving best value, from project inception to eventual decommissioning.
2. Enhanced performance
BIM makes possible swift and accurate comparison of different design options, enabling development of more efficient, cost-effective and sustainable solutions.
3. Optimised solutions
Through deployment of new generative modeling technologies, solutions can be cost-effectively optimized against agreed parameters.
4. Greater predictability
Projects can be visualized at an early stage, giving owners and operators a clear idea of design intent and allowing them to modify the design to achieve the outcomes they want. In advance of construction, BIM also enables the project team to ‘build’ the project in a virtual environment, rehearsing complex procedures, optimizing temporary works designs and planning procurement of materials, equipment and manpower.
5. Faster project delivery
Time savings, up to 50%, can be achieved by agreeing the design concept early in project development to eliminate late stage design changes; using standard design elements when practicable; resolving complex construction details before the project goes on site; avoiding clashes; taking advantage of intelligence and automation within the model to check design integrity and estimate quantities; producing fabrication and construction drawings from the model; and using data to control construction equipment.
6. Reduced safety risk
Crowd behavior and fire modeling capability enable designs to be optimized for public safety. Asset managers can use the 3D model to enhance operational safety. Contractors can minimize construction risks by reviewing complex details or procedures before going on site.
7. Fits first time
Integrating multidisciplinary design inputs using a single 3D model allows interface issues to be identified and resolved in advance of construction, eliminating the cost and time impacts of redesign. The model also enables new and existing assets to be integrated seamlessly.
8. Reduced waste
Exact quantity take-offs mean that materials are not over-ordered. Precise program scheduling enables just-in-time delivery of materials and equipment, reducing potential for damage. Use of BIM for automated fabrication of equipment and components enables more efficient materials handling and waste recovery.
9. Whole life asset management
BIM models contain product information that assists with commissioning, operation and maintenance activities – for example sequences for start-up and shut-down, interactive 3D diagrams showing how to take apart and reassemble equipment items and specifications allowing replacement parts to be ordered.
10. Continual improvement
Members of the project team can feed back information about the performance of processes and items of equipment, driving improvements on subsequent projects.
