Simulation is a process that joins a 3D models with the project schedule allowing all stakeholders to visualize the various phases in a virtual environment. Simulation also, allows improving sequencing by simulating the placement of resources – effectively mapping the model and the delivery time-line together.

4D and 5D BIM 

We develop models of Levels of Detailing LOD 100 to LOD 500. We add Scheduling and Phasing (4D BIM) and Cost Estimation (5D BIM) to the 3D model which facilitates timely and informed decision making and ultimately results in a seamless construction.

Our 4D BIM (Scheduling, Time Model) services include –

  • Project Phasing Simulation

  • Lean Scheduling

    • Last Planner

    • Just In Time (JIT) Equipment Deliveries

    • Detailed Simulation Installation

  • Visual Validation for Payment Approval


Our 5D BIM (Estimating, Cost Model) services include –

  • Real time conceptual modeling and cost planning

  • Quantity extraction to support detailed cost estimates

  • Trade verifications from Fabrication models

    • Structural Steel

    • Rebar

    • Mechanical-Plumbing-Electrical (MEP)

  • Value Engineering

  • Prefabrication Solutions

Energy Analysis

TreisTek uses a properly adjusted BIM model to conduct energy assessments for the current building design. The core goal of this BIM use is to inspect building energy standard compatibility and seek opportunities to optimize proposed design to reduce structure's life-cycle costs.

Why Energy Analysis?

  • Save time and costs by obtaining building and system information automatically from BIM model instead of inputting data manually

  • Improve building energy prediction accuracy by auto-determining building information such as geometries, volumes precisely from BIM model

  • Help with building energy code verification

  • Optimize building design for better building performance efficiency and reduce building life-cycle cost

Lighting Analysis

You can understand and quantify the amount of the sun’s light in your project with daylighting analysis. This can help you create comfortable and beautiful spaces, reduce lighting loads, and reduce cooling loads.

Why Lighting Analysis?

  • You can improve the form of the building/room to get more natural light

  • You can get enough light for specific tasks

  • You can determine the behavior of a given lighting system. This can also include artificial (indoor and outdoor) and natural (daylighting and solar shading) lighting.

  • Based on this analysis further development and refinement of the lighting design takes place to create effective, efficient, and constructible lighting systems.

  • It allows for performance simulations that can significantly improve the design

Pedestrian Simulation

Pedestrian Simulation is an accurate representation of the human walking behavior and dynamics in a virtual environment. 

Proximity Modeling: Proximity Analysis gives the insights to understand scenarios for operating sites or structures in a ‘new normal’ situation. An essential part of the toolbox for architects, urban planners, property owners or facilities managers for now and into the long-term future.

Agent Based Evacuation: Advanced movement simulation combined with high-quality 3-D animated results.

Our 4D Construction BIM can be used for the following-

  • PRE-BID presentation

  • Time line services 

  • BIM construction phasing 

  • Construction sequence planning
