The Challenge

The client, a Spanish multinational retail clothing chain, planned store expansions across India but faced major roadblocks due to outdated and inaccurate built data:

• New Delhi: Expansion was hindered by undocumented slanted beams and uneven slabs, making structural design difficult without accurate as-built information.
• Bengaluru: Code compliance for escalators, staircases, and lifts was unclear due to missing and outdated layout data.
• Mumbai: Facade modifications required precise elevation details and panel/mullion information, which were unavailable.

‍Client’s Initial Hurdle

• Outdated or missing built information caused delays and design inefficiencies.
• Poor data impacted space planning and facade updates, leading to execution issues.
• Unclear requirements for structural changes raised safety and regulatory concerns.
• The client’s team was unfamiliar with BIM and laser scanning tools, making adoption difficult.

Why This Was Critical

Why was accurate as-built data important?

It was essential for space planning, structural analysis, and code compliance. Without it, the risk of design errors and construction delays was high.

Why use laser scanning?

It provided highly accurate 3D data, especially for complex or uneven structures something manual methods couldn’t match.

How did outdated data affect design?

Because if the BIM model didn’t match the live site conditions, decisions made using the model would be flawed impacting installation and procurement.

How was the client’s tech gap addressed?

We offered workshops, guides, and training to help their team work confidently with BIM and Trueview files.

What was the value of Trueview walkthroughs?

They allowed virtual site exploration, helping the client visualize spaces and make informed design decisions.

Gaps in Existing Information

• New Delhi: No accurate data on slanted beams and uneven slabs, making structural planning difficult.
• Bengaluru: Missing updates on partitions and vertical circulation areas, affecting code compliance.
• Mumbai: Incomplete facade details, like elevations and mullions, and delayed modification planning.

‍Why Specific Requirements Mattered

• Accurate As-Builts: Essential to avoid design errors, delays, and ensure modifications matched real site conditions.
• Code Compliance: Critical for safe design, especially in staircase, lift, and escalator zones.
• Efficient Planning: Reliable measurements enabled effective space use and precise facade alterations.

The Desapex Solution

To address these challenges, we utilized laser scanning technology to capture precise as-built data of the store locations. The process involved:

• Conducting site surveys using Leica TruView 22 for 360-degree scans.
• Developing BIM models in Autodesk Revit to reflect accurate site conditions.
• Generating Trueview walkthrough files to allow virtual navigation of the stores.
• Providing site visit reports and point cloud data to supplement the BIM models and ensure all aspects of the existing conditions were captured.

This solution allowed the client to make informed decisions based on the most accurate, up-to-date data available.

Project Timeline & Milestones

The project was scheduled with 8 working days for each store (approximately 30,000 sqft per store):

• 1 Day: Site survey and laser scanning
• 7 Days: Deliverables including site visit reports, Trueview walkthrough data, and as-built BIM models and drawings

Software & Technology Used

• Cyclone Register 360
• Autodesk Revit 2021
• Autodesk Recap Pro
• Leica TruView 22
• Revu Bluebeam

The Real Business Value Delivered

• Code Compliance: Accurate data ensured safe, regulation-compliant modifications.
• Better Planning: Enabled precise space layouts and functional designs.
• Smooth Modifications: Detailed facade data supported efficient exterior updates.
• Fewer Surprises: Real-world as-builts minimized errors during fit-out.
• Improved Collaboration: 3D models and walkthroughs boosted remote decision-making and teamwork.

What This Means for Future Projects

The successful implementation of BIM and laser scanning technologies has set a new standard for the client’s future store expansions. The ability to access accurate, real-time data for each store's unique needs will streamline future designs and modifications, reduce the risk of delays, and enhance overall project efficiency.

With this foundation, the client is now better equipped to handle the complexities of store renovations and expansions. The integration of advanced technologies will enable them to make faster, more informed decisions, ensuring smoother processes and greater project success moving forward.

By leveraging the lessons learned from this project, the client will continue to optimize their store designs, ensuring that each new store and renovation is completed with greater accuracy and fewer complications, ultimately setting a benchmark for future retail projects.
