The creation of 3D, 4D, 5D BIM is included in BIM services. But it is necessary to know about 4D and 5D BIM and their advantages. Let’s have a look over their definition and advantage.
There are various activities in a construction project at the same time, which involve people, materials, and equipment. So you need to know their quantity, their cost and manage and track their schedule. But traditionally, the mentioned scheduling was done through a one-dimensional timeline sheet where it was not possible to get a real-time update, make easy modifications, and identify unforeseen material shortages and workspace clashes. Best Structural BIM Services in Australia provides more than a 3D modeling, and it allows to add the 4D of time and 5D of the cost that facilitates easy and effective management of the whole construction process.
The work of 4 dimensional BIM is to add the scheduling data of the project even before the construction starts. To improve efficiency, the contractors can link the activities of one discipline with the other and organize management planning in a manner. On the other hand, 5 dimensional BIM is linked to the cost, and its work is to generate the bill of materials, development rates, and the overall cost.
There are a lot of different disciplines and elements that are involved in the construction site, and with a wide range of information, there is a lot of human error, which can be due to inaccurate project planning where there may be 4D clashes that were not detected, or it may be due to the changes made in the design, but this does not happen with all the interrelated aspects leading to the inconsistency of materials that are ordered, or it may also occur due to one material being ordered to deliver at the wrong time causing a delay in all the consequent project aspects.
4D BIM services:
This type of BIM service represents building data in the form of a timeline featuring the duration of construction integrated with the 3-dimensional geometry of the building, and also it evaluates the overall design features on the construction schedule and workflow. Also, during the construction process, 4D scheduling provides a host of tangible and intangible benefits by providing precise and useful construction project information.
With the help of 4 dimensional BIM modeling service, the structural engineers can prepare a construction task schedule by linking the model elements to the timeline. It is used to create a simulation video for the construction project in
a 4D environment that shows every building construction stage. It allows the creation of a virtual mockup of the construction system design that helps to identify workflow-based clashes, and it also helps to manage the supply chain for materials and the labor required on the construction site. The other name of virtual mockups is sequenced-based simulations that help the contractors in communicating the complex processes to the whole team in order to improve the overall productivity onsite. 4D BIM, when used with clash detection service, is used in detecting workflow clash that mainly occurs when the schedule for two or more tasks is wrongly arranged at the same time. According to the modified design, if any modification is done within the design, the project schedule and cost modification are also automatically updated.
5D BIM services:
This type of BIM service is a modeling process that adds cost information to the 3D model. The cost data from the 5D services are integrated within the BIM model objects themselves. This type of modeling service helps the structural engineers to create a relationship between elements, and it consists of the properties and specifications of each element and object where they can extract complete and accurate information from the model used for costing. By knowing the quantity of the particular component, the cost estimates are done: the capital cost of purchasing it, installing it, the running and maintenance cost, and the anticipated price of renewing the cost in the future. Thus the structural engineers need to have the correct data in the 3D model since it would be used to calculate the cost.
Advantages of 4D BIM
To streamline the scheduling and planning of the construction phase, 4D BIM is extremely valuable. The visual step-by-step process of 4D BIM comprises various information regarding time in the construction sector, such as lead-time, time taken for construction and installation, allowances for drying and mixing, etc. It is also used to detect any inconsistencies and allows to make requisite changes. A properly planned construction schedule of 4D BIM services enables resource mobility, better resource planning, and optimal resource utilization. Finally, when they all are involved in the project, they all know what and when they are working on it, which increases collaboration.
Advantages of 5D BIM
With the help of 5D BIM, it becomes easier to get more precise and faster quantity take-offs. In BIM services, whenever a single component is modified, its direct impact is calculated in 5D BIM, ensuring that the information is always consistent with the design. A lot of time is saved as errors with automation of quantity take-offs that arise from human errors, are reduced. By accessing quantity take-offs and bills of quantities, the contractors can get updated material lists and speed up the material procurement. In todays’ advanced world, the 5D BIM, with the help of cloud technology, it is possible for the stakeholders to get proper access to the data from anywhere without actually being present on-site, which enables easy coordination with other stakeholders and also it makes easy for them to inform every change in schedules or change in design or plans.
5D BIM modeling services also enable the contractors to gain accurate cost data, and it helps them develop a reliable cost estimate of the entire project right from the starting. In addition, since the calculated cost is based upon the material specifications and quantities of any changes in the component or the design, that is automatically taken into account and reflected in the BIM model, which ensures the cost stays consistent with the design.
