BUDGET: 10 crore INR and above (USD1.48 million and above)
Project Overview
Historic Monument Mapping: Implemented a world-class permanent 3D Projection Mapping show at the 11th-century Rani Ki Vav stepwell in Patan, Gujarat.
Global Technological First: Recognized as the world’s first subterranean (underground) monument to integrate a permanent projection mapping system.
Strict Preservation Standards: Executed all works under the stringent custody and structural guidelines of the Archaeological Survey of India (ASI) at a protected UNESCO World Heritage Site.
Turnkey Engineering Delivery: Managed the entire life cycle on a complete turnkey basis, handling everything from supply, installation, and testing to system integration.
Artistic Site Illumination: Deployed specialized facade lighting, custom pathway safety tracks, and dedicated heritage illumination throughout the monument grounds.
Long-Term Asset Management: Retained full responsibility for daily operations, calibration, and technical maintenance under a 5-year Defect Liability Period (DLP) framework.
What did the client want to achieve?
Night Tourism Transformation: Create a highly engaging, nighttime edutainment asset for the Tourism Corporation of Gujarat Limited and the ASI.
“Hidden in Plain Sight” Mandate: Ensure the entire AV technology and power layout remains completely invisible to the public during daylight hours.
Aesthetic & Heritage Protection: Preserve the visual sanctity, delicate ancient stone carvings, and global architectural integrity of this highly celebrated UNESCO site.
100% Non-Invasive Integration: Avoid any permanent modifications, drilling, or scarring to the core historical facades and tiers of the stepwell.
Zero-Visibility Tech Infrastructure: Ensure that no modern hardware—including projection enclosures, massive sound equipment, lighting arrays, or power cables—is visible during the day.
Buffer Zone Preservation: Apply the strict aesthetic concealment standards globally across the stepwell interior, surrounding tourist pathways, and buffer gardens.
Scope of work your company was involved in
Turnkey Operations: Fully managed the supply, testing, commissioning, daily operation, and comprehensive maintenance for a 5-year duration.
High-End Projection Array: Deployed 10 high-lumen, high-resolution laser projectors engineered to throw visuals downward into the deep stepwell layout.
Subterranean Civil Infrastructure: Constructed heavy-duty, engineered underground pits to house the projection units below ground level.
Media Processing Framework: Integrated high-performance Media Servers and automated script control engines capable of pushing multi-language content to global audiences.
Acoustic & Sound Integration: Designed a fully synchronized, weather-proof surround sound system optimized for complex outdoor open-air spaces.
Bespoke Illumination Tracks: Installed custom-built LED heritage lighting and specialized pathway illumination tracks tailored specifically for a show environment.
Centralized Control & Power: Erected a master operations control room equipped with industrial-grade Uninterruptible Power Supplies (UPS) and dedicated electrical distribution grids.
What key challenges were faced?
Subterranean Geometric Physics: Navigating a deep, multi-tiered (7 Floor)underground stepwell that required projecting downwards rather than horizontally.
Fixed Structures Forbidden: Overcoming a strict regulatory veto by the ASI that banned the installation of permanent above-ground steel poles or projection towers.
Strict Environmental Aesthetics: Managing a high-brightness show without leaving any permanent footprint, exposed wires, or heavy enclosures to disrupt the historic day landscape.
Millimeter Projection Accuracy: Ensuring that massive projectors hidden during the day could accurately align and project flawlessly onto asymmetrical ancient stonework every night.
Invisible Cable Management: Routing hundreds of meters of high-voltage and data cabling without digging up protected heritage paths or mounting trays on historical walls.
How were those challenges resolved?
Automated Subterranean Hydraulic Lifts: Engineered a global-first innovation by mounting the 10 laser projectors on custom hydraulic lifts inside underground pits.
Perfect Landscape Camouflage: Designed the subterranean pits with surface lids layered in natural soil and grass, rendering the systems 100% invisible to daytime tourists.
Robotic Dynamic Positioning: Programmed 8 major lift systems to elevate in perfect synchronization right before showtime, extending to precise, predefined heights.
Smart Self-Calibration: Integrated advanced auto-calibration sensors that automatically verify and correct image alignment immediately upon lift extension.
Retractable Infrastructure Cycle: Configured the entire projector lift array to automatically retract back down into secure, sealed underground pits the moment the show ends.
Cable-Free Acoustic Array: Eliminated structural wire runs by deploying a high-performance portable, wireless surround sound system set up daily and removed nightly.
Architectural Stone-Housed Lights: Enclosed all permanent LED heritage fixtures within custom stone housings matching the exact color, texture, and masonry of the 11th-century site.
How has your work helped the client?
Extended Revenue Hours: Shifted the monument’s historical public closing hours from 6:00 PM to 9:00 PM, introducing a new era of night tourism.
Significant Regional Economic ROI: Boosted regional tourism revenue by more than 30% by driving overnight tourist stays and hospitality spending in Patan.
Cultural & Educational Value: Provided a massive, high-impact edutainment tool showcasing the history of the Solanki dynasty and the engineering brilliance of the stepwell.
Immediate Public Adoption: Registered an exceptional footfall milestone by drawing more than 50,000 visitors within the first two months of operation.
Perfect Regulatory Alignment: Successfully balanced cutting-edge, high-budget digital entertainment with total compliance under strict, unyielding ASI heritage conservation guidelines.
What are you most proud of about the project?
Pioneering a World-First Concept: Successfully executed a permanent 3D projection show on a delicate subterranean monument using retractable, automated robotic lifts.
Engineering Over Compromise: Refused to dilute the client’s creative vision or the ASI’s preservation rules, choosing instead to re-engineer how AV hardware dynamically moves.
Flawless Mechanical Synchronization: Achieved highly stable, repeatably accurate millimeter calibration across multiple lifts operating daily in outdoor conditions.
A Standard for Global Heritage Sites: Set a brand-new global benchmark for how modern AV integration can seamlessly coexist with sensitive UNESCO archaeological sites.
Maximum Client Satisfaction: Delivered an error-free, highly lucrative project that surpassed all operational, aesthetic, and financial goals for the Tourism Corporation of Gujarat.
