Client Profile:

The client is a leading surveying firm with 50+ years of experience offering measurement and surveying services to the property, rail, and infrastructure sectors in the UK.

Business requirements for the point cloud to Revit modeling project:

The client was commissioned to renovate and modernize a large shopping mall measuring 310,000 sq. ft in the UK. Given the complex nature of the mall spread across multiple stories and unique architectural designs, the project needed meticulous planning.

The client used advanced surveying and laser scanning technology to generate 3D laser point cloud scans and 360-degree photos of the mall's structure.

They employed Hitech CADD Services as a strategic partner to:
• Convert laser scans into detailed 3D BIM models for architectural and structural disciplines
• Create a detailed representation of the exterior features in alignment with the as-built conditions

Challenges faced while implementing the point cloud to Revit modeling project:

Hitech CADD Services's team conducted a comprehensive assessment of the project's scope and identified the following challenges:

• Balancing the preservation of the building's existing features while accurately modeling its geometrically intricate structure
• Ensuring a high level of accuracy (within +/-10 mm) for the as-built model within a tight timeframe
• Addressing the issue of unclear scan data in certain areas of the building

Solutions and approach:

The team of Revit experts at Hitech CADD Services successfully created a content-rich 3D point cloud to Revit model of the shopping mall, capturing all intricate details such as the exterior, roof, escalators, access points, and structural components.

For this, they first analyzed the scanned data and images provided by the client, converting them into comprehensive 3D BIM models for both the architectural and structural components of the mall.

The models were then populated with relevant equipment and structural elements such as exteriors, roofs, escalators, access points, etc.

The team also generated precise quantity take-offs with accurate scheduling to help the client plan proper resource and material allocation.

Specific Revit families were created for different categories of structural and architectural elements, adhering to established standards.

Business impact of the point cloud to Revit modeling project:

The high level of accuracy of the 3D point cloud to Revit model:
• Streamlined the renovation process reducing any unnecessary iterations
• Resulted in cost and time savings through enhanced scheduling and precise quantity take-offs
• Increased on-site construction safety due to the improved planning and information available
• Enabled the client to reuse the model for future renovations and additional design enhancements
