Scan to BIM Transformed a $300M NYC High-Rise: $18M Savings & 20% Less Rework

In the heart of Manhattan, Optimar Precon supported a $300 million, 40-story commercial high-rise that redefined modern workspaces. The 600,000-square-foot development included office towers, retail spaces, and sustainable features. The project also targeted LEED Gold certification.

Given the scale, complexity, and tight 24-month schedule, the project required flawless coordination and digital precision. Our experience in Revit, Navisworks, and ISO 19650-compliant workflows helped drive accuracy, reduce risk, and align with the client’s sustainability and cost goals.

The project began with outdated, incomplete 2D PDFs from the 1990s. These legacy documents led to coordination issues between architectural, structural, and MEP teams—putting 15% of the budget at risk due to potential rework and three-month timeline delays.

The client also had to comply with New York’s strict building codes and meet LEED certification standards. Manual updates to these drawings were slow and error-prone. A shift to 3D BIM was essential to avoid delays, reduce clashes, and accurately visualize every layer of the building before construction.

Optimar Precon deployed a full-scale Scan to BIM strategy that converted outdated files into a centralized 3D model:

• Point Cloud Integration: We laser scanned the entire site, generating a point cloud with 2mm accuracy.
• PDF to BIM Conversion: 500 legacy drawings were transformed into a parametric BIM model in Revit, including structural, architectural, and MEP elements.
• Clash Detection: Over 300 conflicts (e.g., ductwork through structural beams) were detected in Navisworks and resolved digitally—before reaching site.
• ISO 19650 Compliance: The model followed global standards to ensure data quality and interoperability.
• Cloud Collaboration: The BIM model was hosted on a Common Data Environment (CDE) for real-time access and coordination across all project teams.

We also integrated LEED-focused design elements, such as high-efficiency HVAC systems and sustainable materials, and ran 4D construction simulations to manage sequencing and avoid delays.

The implementation of Scan to BIM and clash detection delivered transformative outcomes:

• $18M in Cost Savings from clash resolution, reduced waste, and efficient coordination
• 20% Less Rework by resolving issues before construction started
• 6 Weeks Saved in the planning phase (25% faster than projected)
• 15% Energy Use Reduction, supporting the building’s LEED Gold certification
• 92% Bid-Hit Ratio, thanks to accurate BIM-based takeoffs and specs
• 98% Stakeholder Satisfaction with coordination and access via the cloud model

The client praised our responsiveness and technical precision, noting that our cloud-based collaboration tools streamlined communication across teams in New York and remote offices.
