Understanding 3D Modeling, 4D Modelling, and Visual Animation

While 3D modeling is a familiar concept, not everyone knows the power of 5D BIM modeling technology. This innovative approach incorporates two additional dimensions that greatly impact construction: component pricing and time.At Constructive U.S., our primary goal is to provide clients and stakeholders with a comprehensive model of the project at hand, and our BIM modeling services are instrumental in achieving this objective.

Let’s delve deeper into 3D modeling, 4D modeling, and visual animation.

  •  3D Modeling: A virtual representation of physical objects in three dimensions (x, y, z) as surfaces or solids. It encompasses Existing Conditions Models, Design Models, and Construction Models. Construction Models typically incorporate temporary site features and equipment such as detours, temporary signals, utility excavations, and falsework.
  •  4D Modeling: This simulation combines virtual models linked to the current CPM Progress Schedule, presenting model elements/objects in an ordered, time-scaled manner. A 4D model must consist of one or more virtual models and at least one link to a CPM schedule.
  •  Visual Animation: A walk-through of a virtual model that supports movement and display, incorporating photo simulations to accurately depict existing and construction build-out conditions above and below ground.

The Essence of BIM 5D Modeling

BIM 5D modeling is the fusion of 3D CAD components with scheduling constraints and budgetary considerations, enabling the entire construction team to visualize the expenses and progress of all construction activities over a specific period.Our professional BIM modeling services have the potential to revolutionize the management of construction projects, regardless of their size, location, or complexity.

Diverse BIM Models

At Constructive U.S., we recognize the significance of integrating Building Information Modeling (BIM) with cost and revenue-loaded construction schedules.Our team of BIM model experts and specialists stays updated with the latest technology, utilizing industry-leading software such as AutoDesk – Revit, Bentley Suite, and Civil 3D. Over the years, we have successfully created multiple 5D models for various projects, delivering useful insights to contractors and owners. Our comprehensive suite of services includes different BIM models, such as:

  1. Design Intent Model: The architect creates this BIM as a reference for the Contractor to develop the Construction Model. The BIM provides design intent and undergoes development at a LOD (Level of Development) 300.

  2. Construction Model: The Contractor initially receives a copy of the Design Intent Model, which they maintain and update throughout construction. The Contractor also resolves clashes in the model. They develop the BIM at a LOD of 300.

  3. Fabrication Model(s): Each discipline or trade subcontractor in the project generates these BIMs. A Fabrication Model can comprise multiple models representing different subsets of each discipline or trade. The models are developed at a LOD of 400 and play a crucial role in extracting fabrication and shop drawings.

  4. Federated Model: This BIM is a composite of the Fabrication and Construction Models and the Design Intent Model. Its purpose is to review space coordination and constructability.

  5. As-Built Model: Developed by the Contractor as a record of the construction work, this BIM is created at a LOD of 400 and handed over to the Construction Manager after substantial completion.

  6. Record Model: The A/E maintains it throughout the construction period, coordinating it with the Contractor. It assists the A/E in generating changes to the Contract Documents during construction. The A/E develops this model at a LOD of 300.

To ensure seamless coordination among all parties involved, we develop detailed and comprehensive BIM Execution Plans (BEP). These plans facilitate accurate model-based estimating, a vital component of any cost plan.

Understanding Levels of Development

At LOD 300, we accurately model Model Elements as specific assemblies in quantity, size, location, and orientation. People commonly use this level for A/E models like the Design Intent Model. At LOD 350, Model Elements are graphically represented within the model as a specific system, object, or assembly, incorporating quantity, size, shape, location, orientation, and interfaces with other building systems.


At LOD 400, Model Elements are graphically represented within the model as a specific system, object, or assembly, providing size, shape, location, quantity, orientation, detailing, fabrication, assembly, and installation information.

This level is suitable for fabrication and assembly, and speciality trade contractors and fabricators utilize it to build and fabricate project components, including MEP systems. At Constructive U.S., we develop comprehensive and detailed BIM Execution Plans (BEP) to facilitate seamless coordination among all project stakeholders. Our expertise in BIM modeling ensures accurate and effective model-based estimating, delivering superior results for your construction projects.
