The Challenge

A leading global technology products and services firm planned to expand their existing Hyderabad campus by adding one more floor. However, the project hit a roadblock early on  the absence of reliable as-built data and inaccurate area statements made it nearly impossible for the client to confidently plan the renovation and fit-out work.

Client’s Initial Hurdles

• No verified as-built documentation was available for the campus.
• Inconsistent area statements across the campus buildings.
• Inability to visualize core and shell structures for fit-out planning.
• Urgency to begin renovation while ensuring minimal rework risk.
• Lack of clarity around existing MEP services and structural conditions.

Why This Was Critical

Why couldn’t the renovation start with the drawings already available?

The existing architectural and structural drawings were outdated and lacked verification against on-site conditions, making them unreliable for precise planning.

What risks did the client face without verified as-built data?

Proceeding without accurate data could have led to major rework, delays, and budget overruns during interior fit-out.

Why was time a critical factor in this project?

Missing or inconsistent equipment details could result in maintenance delays and increase downtime during peak usage periods.

How did the missing data impact design decisions?

To leverage the rich spatial and technical data already created during design and construction, minimizing duplication of work and enabling location-based asset management.

What did the client stand to gain with a digital twin?

A reliable BIM model based on laser scans would serve as a single source of truth, enabling informed decisions and streamlined coordination.

Gaps in Existing Information

• No digital representation of the building’s current condition.
• Missing or incorrect dimensions across levels and zones.
• No access to service routes, ceiling voids, or structural alignments.
• Difficulty in identifying façade geometry and external boundaries.

Why Specific Requirements Mattered

• High accuracy was non-negotiable due to tight tolerances in fit-out.
• Core and shell modeling needed to support multiple downstream teams interiors, MEP, and procurement.
• Timely delivery was essential to keep the overall project timeline on track.
• The digital model needed to reflect not just geometry, but also actionable data such as room-wise area breakdowns and photo documentation.

The Desapex Solution

Desapex deployed a fast-tracked digital capture and modeling strategy:

• Conducted laser scanning of the entire base build (core and shell), using 2 laser scanners and 2 survey technicians simultaneously to meet the deadline.
• Registered point cloud data with Leica Cyclone Register 360 and Trimble Realworks.
• Delivered as-built BIM models (ASMEPF) using Autodesk Revit, enabling downstream design teams to coordinate confidently.
• Shared detailed room-wise area statements and site images to support early planning.

‍Project Timeline & Milestones

• Week 1: On-site laser scanning completed across all floors and external facades.
• Week 2–3: Point cloud registration, model creation in Revit, and validation.
• Week 4: Sheet generation and delivery of final as-built documentation.

Software & Technology Used

• Autodesk Revit
• AutoCAD
• PDF viewer
• Leica Cyclone Register 360
• Trimble realworks

The Real Business Value Delivered

• Client’s interior design team could initiate design confidently with verified inputs.
• Reduced rework risk by aligning plans with actual site conditions.
• Ceiling scans revealed existing MEP services and beam layout  key for conflict-free coordination.
• Facade and campus dimensions supported BOQ preparation and vendor tendering.

What This Means for Future Projects

This project was more than just about producing accurate drawings it marked a shift in how the client approached their built portfolio. Previously, their expansion projects were reactive, often resulting in delays, added costs, and low team morale. Through this engagement with Desapex, they discovered the value of starting with verified data and a digital twin that reflected real conditions.

Now, instead of relying on legacy drawings or guesswork, they operate with clarity and precision. The success of this initiative gave them a new blueprint for future projects  be it a retrofit, expansion, or upgrade. With laser-accurate data and BIM-driven coordination, they’ve embraced a digital-first mindset, paving the way for smarter project delivery not only in India, but across global campuses.

They’ve moved from asking “Where do we start?” to confidently stating “We know what we have let’s build from here.”
