BIM Collaboration and Documentation Setup.

The process of BIM Plan preparation, is very important especially when collaboration is intended between various consultants. In case of large scale projects, BIM model management and linking is crucial to the success of the project.


A Pre Contract BIM plan should include
A project implementation plan with the details and stating the capability and competence of the collaborators
Goals for collaboration and information modelling.
Project milestones in line with the project programme
Deliverable strategy.

Site Grading with Cut & Fill Calculations.

For contoured sites and project with many levels it can be a challenge for cut fill analysis. Implementing a BIM process for site design helps with the creation of coordinated, reliable design information about the project. Modern 3D scanning processes elevates the site accuracy to new levels not achievable in conventional surveying techniques. Integration of thi s data in the site model results in an intelligent 3-D model of the site in which elements of the design are related to each other dynamically with a rich set of information and the attributes associated with it. This information is readily available from the conceptual stage of the design. This would be especially beneficial for achieving LEED points in top soil conservation.

Building Simulations

Once an accurate Revit model is prepared Building simulation can be conducted for a varying purposes like-


Elevation Study
Solar Path Study
Daylight Study
Light Pollution Control


Designs can be experimented and compared on the true workability in aesthetics, function or Behavioral patterns with actual scale visibility and real-time parameters of visibility, Context, Features, Form, Structural stability, climatic behavior or simulated analysis.

Interference Checks and Clash Resolution

The detailed MEP models can be interfaced with Architectural and Structural models for interference checks and clash resolution to negate clashes which were traditionally detected during construction. Errors and omissions which are often undetected in two-dimensional drawings can be visually detected and resolved during project reviews. These dimensionally accurate models can be clash and clearance checked, allowing spatial conflicts between disciplines to be tracked and resolved, before commissioning construction. This has the added advantage of allowing the contractor to commence site works with the assurance of negligible design related disruptions.

4D Sequencing with Time Scheduling.

4D sequencing is the process of intelligently linking 3D Components / assemblies with Time & Schedule related data/information. The construction of the 4D models enables the various participants (from architects, engineers designers, contractors, PMC to clients) of a construction project, to visualize the entire duration of a series of events and display the progress of construction activities through the lifetime of the project while Construction. This BIM-centric approach towards project management technique has a very high potential to improve the project management and delivery of construction project, of any size or complexity. So The Onsite Project Manager can see things in 3D Graphical format as per related milestone of the project, and compare it to actual Progress on site.

5D or Energy Analytical Models (Concept and Detailed)

The Revit model can be utilized in conjunction with Autodesk EcoTect analyis to conduct detailed Energy analysis. creating models suitable for day lighting analysis, solar shading studies, computational fluid dynamics (CFD) modeling, energy analysis etc. It is often required to use different models and different tools for different types of analysis, at different points of time in the process. In early-stages, conceptual energy modeling helps you to answer big questions about the building’s form. Later-on, detailed energy models can help to answer questions about the systems that meet the building’s energy demands (HVAC, lighting). Revit simplifies the process of Energy analysis from the conceptual stage making the attempt to attain Green Points easier.

In energy modeling, the results are based on:
The building geometry (i.e. shape, layout, wall constructions)

BOQ Generation and Validation

Manually Generation of BOQ is painful & lengthy process and takes days to months depending upon size of the project. By adopting BIM, one can generate effective & Accurate BOQ at any stage of project (in very short time) since you are designing in 3D with actual items and assemblies. One can use Family / contents from a vendor website which is actually going in the Final List, eventually enriching the BOQ.

Design and Construction Documentation

Design & Construction Documentation is a fairly easy process as you are actually not drafting but doing the Virtual Construction. So one can duplicate things, can have ‘n’ no of sections, can have many details. You can extract Door Window Schedule, Material / Finishes Schedule, various perspective and everything which goes in a Effective Documentation Set. Change Management in Design is easy as related things get updated automatically, unlike in CAD process where one has to actually modify things
An example is the Childrens Mall at Katara. In this building it was difficult to complete the traditional GFC package using conventional means. We therefore had to resort to a Revit model with proper annotation from which a GFC package was produced

Sight-line Analysis for Stadiums and Auditoriums

An interesting application of BIM has been used for Sightline Analysis of FIFA 2022 Stadiums in Qatar. FIFA has strict guidelines for the visibility criteria for spectator seats in a FIFA event. An LOD 100 model of the bleacher stands and the stadium were developed and C value analysis of the individual seats were carried out to calculate the seat kill factor. Seats not meeting the criteria were quickly redesigned to conform to minimum standards.

Facility Management

Building Information Modeling is much more than a 3D CAD drawing representing a floor plan or construction detail. BIM includes data of interest to many stakeholders during the full lifecycle of the building, such as buyers, owners, occupants, facility and real estate managers, safety inspectors, lawyers, and emergency planners. BIM can also support in creating surrounding processes, including geographical analyses, urban planning, and landscaping. The real use it can support the Facility Mangers throughout lifecycle. One can see spaces virtually while selling the spaces, can make and see things while doing updations / alterations later. One can link the model with various services including BMS.
