BIM FAQ

What Is BIM?

Building information modeling (BIM) is a digitized platform to reinforce development by several tools, encompassing the creation of digital representations of buildings including the physical and the functional attributes. BIM utilizes the 3D, 4D, 5D, 6D, 7D and 8D modeling concepts, IT and software interoperability for designing, construction and operation of building projects.

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 Is BIM Scope in the Project Life-cycle?

Usage of Building Information Modeling (BIM) extends beyond the planning and design phase of the construction project, throughout the building life cycle. The subsidiary methods of building lifecycle management comprise of cost and construction management, project management, facility operation and application in green building.

How Is Building Model Managed?

Building information models encompass the entire concept-to-occupation time-span. To ensure competent information management throughout this span, a BIM manager or a Virtual designer to a construction manager or a project manager is appointed. The BIM manager tracks the object-oriented Building Information Modeling from the pre-design phase to the stage of final-built against projected performance objectives. The model supports analysis, schedules, quantity take-off, logistics and more. AEC (Architectural, Engineering, and Construction) professionals are now developing BIM in various levels of details from LOD 100 to LOD 500.

How BIM Aids in Construction Management?

AEC project stakeholders in the construction process always face the challenge to deliver successful projects in spite of tight budgets, limited manpower, faster schedules, and incomplete or contradictory information. Disciplines like architectural, structural & MEP (Mechanical, Electrical & Plumbing) designs should be well synchronized, as two things can’t take place at the same place and time. Furthermore, BIM helps in identifying clashes and conflicts, specifying the exact location of discrepancies. BIM envisages the virtual construction of a facility before the actual construction, to minimize uncertainty, enhance safety, resolve problems, and simulate and analyze potential impacts. Sub-contractors can put information into the 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.

What is BIM Facility Management?

Building Information Modeling (BIM) helps construction professionals to bridge the information loss associated with managing a project from design & construction team to building owner & operator. BIM facilitates every construction project stakeholder to add and refer back every information acquired to BIM model. This yields 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 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 BIM software application to support an analysis of building operation and maintenance. BIM 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.

What Is Green BIM?

Building Information Modeling (BIM) in green building or “green BIM” is a process of facilitating architects, engineers and construction professionals to increase sustainability in the construction industry. The technique helps all AEC professionals to integrate and analyze environmental issues in their design over the building lifecycle.

What Are the Barriers to Industry Implementation of Building Information Modeling?

BIM can bring a paradigm shift to the construction industry – this concept will not work without industry standards and interoperability.

  • Technology & software – Without industry standards & interoperability, it is difficult to share building models. This leads to a problem as Building Information Modeling entails collaboration.
  • Legal complications – Greater accountability within architectural and construction communities prevent industry implementation of BIM.

How Much Does It BIM Cost to Implement?

There isn’t any specific answer to this question. However, to get an idea of the cost, you should consider what it takes to implement BIM like software license, new hardware, new staff, software training, and more. Adopting BIM in construction workflow can be a bit expensive, but keeping in mind the major cost savings associated with projects, BIM should be implemented for both designers and builders accurate work.

What Strategy Should I Adopt for BIM Implementation?

Make a plan, keep it simple and be specific. Focus on tangible objects. Avoid implementing on multiple projects before you get a positive response of using BIM on one project. Don’t overvalue BIM or make promise that you can’t keep. If you are new to the market Tejjy Inc. provides BIM hiring and training of designers, modelers, architects, BIM professionals, contractors to assist your working capacity and boost your profitability.

Do BIM Requires Logistic Planning?

  • Pick a first project to test the process on.
  • Invest in BIM software, hardware, staff & training.
  • Start using the software to develop designs for prototype project.
  • Unless working with a design firm using BIM, create a 3D model of the pilot project using a process referred to as a 2D conversion.
  • Seek BIM consulting services to get assistance on training and implementation.
  • Stay focused on your tangible goals.
  • Include senior management and end-uses in an effective way to gain buy-in & support.

What is the Significance of As-Built Drawings?

As-built drawings are a significant constituent of construction projects. The drawings serve as copies or recreations of the techniques in which the project is created, and pin-point the changes made as it is being built. The revised drawings are created and submitted once a construction project is completed. They encompass all changes made from the initial drawings during the construction process, and provide an exact rendering of the construction and property as it seems after completion.

The As-Built Drawings include:

  • Clear descriptions as opposed to vague phrases
  • Changes in materials used, locations, & sizing
  • Location of utilities including depth and materials of each
  • Unexpected obstructions & solutions used
  • Dates when changes were made
  • Shop drawings and appendices for future use

What Are the Normal Architectural Costs?

About 1,000 homeowners report that an average cost to employ an architect is within the range of $5,272 – $8,536 (cost may vary as per changes in industrial norms). This can be $60 – $125 per hour architectural design fee, or as 5% – 20% of the total cost of the project. The costs normally include the cost to draw plans, or blueprints.

What Are the Different Types of Blueprints?

The process of blueprinting was developed in mid-1800s, when scientists revealed that Ammonium Iron Citrate & Potassium Ferro-cyanide can create a photosensitive solution for reproducing documents.

There are three basic perspective drawings used in architectural design and construction:

  • One-point perspective
  • Two-point perspective
  • Three-point perspective

Why Are the Blueprints of Houses So Important?

Blueprints of Houses are the drawings including construction documents that provide AEC project stakeholders including, owners, general contractors, sub-contractors, and suppliers the required information to bid and build projects. Plan visualization is the initial component of blueprint.

Blueprints of a building can be generated from the 3D BIM Model using Revit software platforms for making architecture drawing floor plan for houses, offices, commercial buildings, and more.
