BIM 3D Modeling Services

Tejjy Inc. provides 3D BIM Modeling services, facilitating clients to obtain complete control of construction projects. Our engineers and VDC consultants collaborate with 3D, 4D, and 5D BIM for project coordination, asset management, risk mitigation, logistic planning as well as cost estimation.

Our Scope of 3D BIM Modeling Work:

We create 3D BIM Model in Autodesk Revit (LOD 400) for architectural, structural, site utility, site logistics and MEPFP services for meeting various project objectives including:

  • Constructability review
  • Clash detection & clash coordination
  • Coordinated drawings
  • Shop drawing validation
  • Marketing Presentations

Benefits of availing our BIM 3D Modeling Services:

  • Team Collaboration– Revit 3D BIM Modeing helps us progress through every phase of the construction project, from 3d floor plan set-up to structural as well as MEP clash detection. Tejjy Inc. BIM team reviews critical areas in 3D for change and evaluates space constraints. We  collaborate design disciplines in a flawless manner, boosting work efficiency, reducing errors, verifying aesthetic looks and enhancing building performance
  • Project Visualization – Using Revit BIM services for 3D model design, Tejjy Inc. produces construction drawings with cutaways, elevations and sections through renderings and animation, bringing the project to life. Our BIM engineers combine Revit design and fabrication models in Navisworks for complete project coordination, avoiding the cost of rework from clashes. A virtual tour of the proposed building (360-degree view) created, through detailed 3D renderings & walkthroughs on the fly, helps us visualize the project at the pre-construction stage.
  • Project Analysis – 3D BIM Modeling plays a significant role in design optimization, coordination and construction management. We work in a coordinated manner, completing projects on time.

We serve the key AEC professionals, including:

  • Architects
  • Structural Engineers
  • MEP Design Firms
  • MEP Contractors
  • MEP Consultants
  • General Contractors
  • Concrete Contractors
  • Drywall Contractors
  • Fire Protection Contractors
  • Home Builders

We extend design to fabrication workflows with 3d modeling:

Optimizing MEP with Revit 3d modeling – Intelligent 3d BIM model helps us design the building systems with improved efficacy, providing project stakeholders a clear idea of design intent and allowing them modify designs for achieving desired outcome, reducing risk of costly changes later.
