The Challenge

Before adopting BIM, the client engaged in a large-scale commercial development in Bande Kodigehalli, was grappling with inefficiencies typical in traditional construction workflows. Fragmented communication, outdated data, and a lack of coordination between multiple consultants and contractors often resulted in costly rework, schedule drift, and design misalignments. Design changes were difficult to track, and updates rarely reached all stakeholders in time. As the project scaled up, these issues became bottlenecks. The client needed a more intelligent, centralized system to align design, construction, and eventual operations seamlessly one that could also lay a digital foundation for post-construction asset management.

Client’s Initial Hurdles

• The project was initially driven by 2D CAD deliverables from design consultants.
• Created multiple friction points during on-site execution.
• Field teams relied on manual sketches and PDF markups, which were hard to standardize or interpret.
• Existing as-built information was either missing or outdated, creating design conflicts, miscommunitcations
• The client needed a unified digital solution to reduce rework, improve coordination, and ensure long-term value post-construction.

Why This Was Critical

What was at stake if the issue wasn't solved?

A delay in occupancy and operational readiness of the commercial building, resulting in revenue loss and client dissatisfaction.

How was it affecting day-to-day operations?

Project managers struggled with poor visualization, lack of coordinated updates, and inefficiencies during coordination meetings.

Were there any compliance or safety risks?

Yes, especially during execution where inaccurate as-built information could have led to major safety or quality compromises.

Why couldn’t existing systems or consultants solve it?

They were limited to traditional 2D outputs, lacked collaborative tools, and couldn’t provide reliable models for future use.

What did the client expect in an ideal outcome?

A reliable BIM model that would serve as a single source of truth, from design through to facility management, with clear visualization, fewer clashes, and enhanced data reliability.

Gaps in Existing Information

• The original CAD data did not reflect actual site conditions.
• Most of the field inputs were in the form of unstructured sketches or PDF markups.
• No single source of coordinated data across teams leading to rework and communication gaps.

Why Specific Requirements Mattered

For this project, accuracy wasn’t just a bonus—it was a necessity. The client’s focus was on not just delivering a high-quality commercial space, but also enabling efficient handover and post-construction facility operations. That meant BIM had to cover everything—from resolving conflicts during design to embedding asset information at handover.

The Desapex Solution

Desapex designed a 6-stage BIM roadmap, It began with a robust BIM Execution Plan, aligning all stakeholders under a shared strategy. During the design development phase, models were built to LOD 350, with rigorous clash detection and resolution workflows. During tendering, we enabled precise quantity take-offs and detailed cross-referenced drawings. On site, models were developed to LOD 400, updated in real time, and used for visualizing construction sequences. Non-geometric metadata was embedded to enrich the model. For the final LOD 500, the model was refined with asset and commissioning data to support Facility Management integration. Whereas the initial data was outdated, Desapex used laser scanning to verify site conditions, bringing the model up to real-world accuracy.

The Real Business Value Delivered

• Reduced Rework & Clashes: Early conflict detection reduced cost and time overruns.
• Accurate Design Inputs: Real-world scans validated the model, aligning it with actual conditions.
• Improved Stakeholder Confidence: 3D models improved engagement and clarity across teams.
• Data-Driven Decisions: BIM helped plan with precision, from tendering to on-site changes.
• Future-Proofed Handover: FM-ready model with all asset and commissioning data embedded.

What This Means for Future Projects

This project was more than a BIM implementation it was a shift in how commercial projects can be planned, executed, and managed.

For Desapex, it validated our ability to deliver full-lifecycle BIM from a strategic Execution Plan to a facility-ready LOD 500 model. It reinforced that BIM, when done right, is a business enabler, not just a design tool.

For the client, the high-accuracy digital twin not only solved on-site coordination issues but also became a long-term asset for operations and maintenance. With embedded asset and commissioning data, they’re now better equipped for ongoing facility management.

For future projects, this sets a new benchmark proving that when BIM is integrated early with the right team and tools, projects are faster, smarter, and better aligned with long-term goals. And at a collaboration level, this was a breakthrough. Multiple teams worked on one coordinated platform, and the result was more than just a model it was a shared understanding and a smoother path to delivery.
