Frequently Asked Questions

What is BIM (Building Information Modeling)?

Building information modeling (BIM) is a digitized platform to create 3d model with spatial information. The spatial information includes physical and functional attributes in building design. There are different levels of dimensions which adds to the benefits of BIM. 3d model is the basic modeling service for coordinated Architecture, Engineering and Construction services. Adopting various  dimensions and level of detailing 3dmodel reflects interoperability for designing, construction and operation of building projects.

Ability to work in point cloud based environment , information can be extracted or exchanged from BIM files to support decision-making about a built asset. Contemporary BIM software applications can be used by individuals, businesses and government agencies to plan, design, construct, operate and maintain various physical infrastructures, like water, waste, energy, gas, communication utilities, and infrastructural facilities like railways, roads, bridges, ports, and tunnels.

What are BIM Dimensions ? How many dimensions are there in BIM?

Building Information Modeling refers to level of detailed information and data entered into 3D model using BIM software. These dimensions of building design comprises of various data related to time, costs, and sustainability. Best BIM companies in us and world facilitate all BIM dimensions with BIM LOD( level of detailing).

How does BIM impact Construction management?

The transformation from CAD to BIM has given a new vision to construction project management. The  3D model facilitates architectural, structural engineering & construction professionals with an insight to plan, design, construct & manage building design for residential and commercial projects. 3D Modeling with its dimensions and level of detailing brings detailed building information. If BIM consultants adopt appropriate BIM softwares like revit, Autodesk, dynamo building lifecycle management with construction sequences can be accurately visualized.

AEC project stakeholders can accurate do cost estimation and quantity take off. 4d bim with naviswork helps in scheduling and tracking online activities of team. Best BIM modelling companies facilitating disciplines like architectural, structural & MEP (Mechanical, Electrical & Plumbing) designs are well synchronized. Furthermore, BIM in construction helps in identifying clashes and conflicts, specifying the exact location of discrepancies making the journey of mep engineering to exist in clash coordinated environment.

BIM and VDC virtual design construction technique before the actual construction, to minimize uncertainty, enhance safety, resolve problems,  simulate and analyze potential impacts. Sub-contractors can put information into BIM model before construction, with prospects to pre-fabricate systems off-site. Wastage can also be reduced and products can be delivered promptly instead of being stock-piled on construction site. Quantity and material extraction can also be done easily. Systems, assemblies, and sequences can be revealed virtually with an entire facility or group of facilities. BIM also minimizes errors through clash detection, where the computer model highlights the building parts (including a structural frame, pipes or ducts) that may wrongly intersect.

Our geographical spread of mines and countries reduces our risk and increases our security of production. It also allows us to identify more opportunities, create synergies across our sites and transfer technology and people around the business.

What is BIM Facility Management?

BIM Building Information Modeling  helps construction professionals to bridge the information loss associated with managing a project from design & construction team to building owner & operator. Best BIM companies facilitates every construction project stakeholder to add and refer back every information acquired by BIM model. These modeling techniques yield advantages to the facility owner or operator.

To take an instance, a building owner may find a leakage in the building. Instead of exploring the physical building, he can take a look at the BIM model to check the location of the water valve in a suspected location. Dynamic information pertaining to the building, like sensor measurements as well as control signals from the building systems, can be integrated within MEP BIM software application to support analysis of building operation and maintenance.

BIM company can be utilized to support a holistic understanding and implementation of building management practices and “cost of ownership” principles that support the full product lifecycle of a building.
