BIM Solutions for Chip Facility Subcontractor Challenges

April 5, 2023

Problem Statement

Create BIM models from the schematic pdf layouts, clash coordinate the models and prepare the field drawings for site installation and Update the BIM models as per changes at the site.

Scope of the work

The Scope of Work included design support for the Electrical, LSS, and Instrumentation and Control Systems for the contracting team. Which included Conduits, Cable Trays, Panel and support modeling, preparing shop drawings and creating as-built models for service installed areas, coordination with other stakeholders for clash coordination, etc.

Key Challenges & How we solved the problem

The existing models received were outdated and were not accurate. This led to clashes and rework during the approval process. This was resolved with the help of 360⁰ images in Cupixworks and laser scanning of the site to verify the site conditions.

Often the inputs received from the Field foreman were in the form of hand sketches or the markups on PDFs for the as-built content. Understanding these hand sketches would take a considerable amount of time. So, instead, we requested for site capture in the form of 360⁰ images and videos, and viewpoints wherever the site capture is not possible.

Outcome or how the client got benefitted

  • Structured documentation and Project tracking.
  • Supported the contractor team to leverage BIM by feeding IFF, technical and circuit details corresponding to each element.
  • Supporting easier navigation through the model using Search Sets, Appearance Profiler for Navisworks, and custom parameters in the model.
  • Faster quantification of materials for construction.

Project Timeline

It took approximately 3 years for 5 buildings with a total area of around 2.5 million sq. Ft.
