New Case Study: RTS Site Applications. Watch now! >
Time animated models are created to represent the planned construction sequence. 4D adds the time dimension of the construction schedule to the 3D model, by linking of each activity off a Gantt chart to the BIM. 4D facilitates the planning of the work and makes communication with other stakeholders easier. We also link the cost or fifth dimension to the 4D BIM, creating 5D cost schedules that facilitates cost-benefit analysis.
Accurate quantification of building components is a constant necessity during the design and construction phases of any project. ENG assists during the Procurement process by providing QTOs generated from the BIM.
Accurate comparative data, combined with optional studies and/or phasing, can be a powerful tool in maintaining and optimizing efficiencies. ENG collaborates with our clients to maximize the value of a model toward these tasks.
Complex site logistics and installation phasing are some of many potential applications for visualization. Graphic representations, created to understand time-based processes, helps foresee conflicts and study potential solutions. 4D adds the time factor of the construction schedule to the 3D model. We can directly link each activity of a Gantt chart (generated in project management software such as Primavera or Microsoft Project) to the BIM. We work with SYNCHRO or Navisworks to create these deliverables.
These animated models represent the planned construction sequence set against time. The main purpose of a construction phasing simulation is to provide a tool that will help the construction team visualize logistical issues or inefficiencies. The simulation exposes details such as out-of-sequence work, scheduling conflicts between multiple trades, “what if” scenarios, and macro-level construction phasing strategies – all in order to achieve the optimization of the construction schedule.
We can also maintain the 4D up to date as construction evolves.
As Presentation Material. On those cases where the CG has yet to win the work and needs to impress his client, we create cost effective 4D animated construction schedules to show the Owner, that the contractor has the work well thought through and that he leverages BIM technology to build efficiently and timely.
Conventional estimating techniques that rely on two-dimensional drawing measurements have substantial potential for ambiguity, inefficiency and error. A three-dimensional project model removes the ambiguity and potential inconsistencies in project quantity estimations.
The fifth dimension (5D) is cost, which is brought into the virtual building life cycle.
A 5D estimate is a BIM linked to construction cost estimation through material quantities that are automatically generated from the data within the model. 5D Estimation improves budgeting, provides cost-loaded schedules, and displays multiple interactive forecasts to make agile comparisons. When the design is changed, cost adjustments are calculated in real time. This enables general contractors to help the owner improve design with value-engineering decisions
All our services can be performed at our own office, communicating via web-based collaboration tools, video calls and traditional phone calls.
However, we also believe that for certain endeavors a personal presence is required in order to increase communication, thereby maximizing efficiency. ENG designed a unique On-Site support business model, where we can provide on-site support by sending our BIM professionals to work at your office or in the field for a period of time (from a few weeks, months or even years at larger projects); while the rest of the team at ENG supports you from our offices.
We also offer different types of contracts to suit your needs, such as Time and Material, Lump Sum and Full-time engagements. Please contact us to discuss your next BIM project.
4D Scheduling is a simulation of the construction sequence generated by linking a 3D BIM model with the project schedule adding time as the 4th dimension. This is represented by the construction sequence typically outlined in a Gantt Chart. There are various platforms with which this integration is usually done, for instance, Navisworks and Synchro, among others.
4D refers to the time dimension added to a 3D model, while 5D refers to the cost dimension added to a 3D model.
4It is another way to call 5D Costing, which is adding the cost information to a 3D model.
In the BIM world, 5D is a 3D model that also includes the Cost dimension. A 5D model is the five-dimensional visualization of a construction project, including not only the 4th dimension of time but also the financial sequence, adding cost data to the model.
By linking in Navisworks, Synchro, or other, each of the elements of a 3D model with its associated task within a construction sequence or project schedule represented in a Gantt Diagram within P6 Primavera or Microsoft Project. It’s important to label both 3D objects and their associated tasks equally.
6D is also utilized for BIM for Facilities Management in the US, although in Europe and other parts of the world the 7D is used for this BIM use, while 6D is used for sustainability modeling. A 6D or 7D model when used as BIM for Facilities management is a model that is leveraged to make property operations and maintenance more efficient.
7D is used to describe the BIM use of Facilities Management, also known as Digital Twining. The main benefits of a 7D model are,
