The Challenge
A global semiconductor manufacturing leader planned a massive new facility in Gujarat, India spanning 16,70,000 sq.ft. However, the project began with a heavy reliance on 2D drawings limiting visualization, slowing coordination, and increasing the risk of clashes across disciplines.
The client needed a comprehensive BIM model that could not only support design coordination but also enable clash detection, modular construction, prefabrication planning, and long-term facility management. Micron- Case Study
The challenge was not just modelling it was building a digital foundation for an advanced manufacturing ecosystem.
Client’s Initial Hurdles
Limited visualization due to dependence on 2D drawings
Difficulty coordinating across architecture, structure, and MEP disciplines
Frequent design revisions without clear markups
Misalignment between design teams and BIM expectations
Need for a model usable beyond design for construction and operations
Why This Was Critical
Why were precise as-built drawings necessary?
The client was mid-way through construction. Any mismatch between actual site conditions and drawings could lead to misaligned interiors, service clashes, and rework all of which are costly.
Why not use traditional survey methods?
Traditional methods could not meet the required sub-3mm accuracy or match the speed needed. With parts of the structure already built, access was limited, making laser scanning the only viable option.
Why was lintel beam detection a sticking point?
Lintel beams are often partially or fully embedded, and even reality capture has limitations when elements are concealed. Still, the client needed these for structural validation and interior anchoring.
How did the timeline affect decision-making?
The 4-week deadline pushed for simultaneous workflows scanning, registration, modeling, and drawing production all had to overlap to deliver on time.
What would success look like for the client?
A reliable, intelligent 3D as-built model and structured document system that enables informed decision-making and safer, faster operations.
Gaps in Existing Information
Frequent design changes shared without clear revision markings
Vendors not fully aligned with BIM Execution Plan standards
Outdated drawings sometimes used for coordination
Inconsistent sheet standards across teams
Limited understanding of BIM processes among stakeholders
Why Specific Requirements Mattered
This was not just a modelling exercise.
The BIM model had to function as a single source of truth across design, coordination, construction planning, and operations.
Accuracy, version control, and collaboration workflows were critical to prevent rework and ensure reliable decision-making across global teams.

Higher model quality: Structured quality checks ensured reliable, high-accuracy BIM deliverables.
Streamlined document management: ACC enabled real-time collaboration, issue tracking, and version control across stakeholders.
What This Means for Future Projects
For the client, this project became more than a modelling exercise it marked a shift toward digitally driven manufacturing infrastructure delivery.
For the project team, BIM transformed coordination from reactive problem-solving into proactive planning.
For Desapex, it reinforced our role as a digital transformation partner capable of building scalable BIM ecosystems for complex industrial facilities.
As semiconductor and advanced manufacturing projects continue to scale in complexity, this engagement demonstrates how a well-structured BIM strategy can move beyond visualization becoming the backbone for construction efficiency, collaboration, and long-term operational intelligence.
