How Columbia’s Irving Medical Center Expanded without Operational Impacts via GPRS CAD & BIM Technology

• The Irving Medical Center, one of New York’s top hospitals, needed to expand its facility without disrupting medical, academic, or research operations.
• The University’s goal was to achieve sustainable, fossil fuel-free facilities, so the design team needed reliable as-builts of architectural, structural, and MEP elements.
• Quick and safe healthcare reality capture was needed to minimize any impact on sensitive, occupied spaces and ensure patient safety.

• GPRS Project Managers coordinated scanning around Columbia’s active academic and healthcare schedule, arriving around 7 a.m. over nine business days to complete work before students began their labs.
• The PMs documented 180,706 s.f., 11 floors, and exteriors with minimal disruption.
• Terrestrial and long-range LiDAR scanners captured interior and exterior conditions across 1,791 scan locations.
• The GPRS Mapping & Modeling Team used the registered point cloud data to create a detailed BIM model with 7,053 elements, with more than:
  
  • 4,500 architectural elements
  • 1,700 MEP elements
  • 275 structural elements
• The CAD designers also created floor plans, reflected ceiling plans, exterior elevations, MEP documentation, and a roof plan over three phases of work.

• Columbia advanced its academic medical center expansion and sustainable energy goals with minimal disruption.
• The design team used GPRS’ 2-6mm accurate as-builts to plan NYC’s first university-owned, fossil fuel-free research facility, supporting Columbia’s 2030 goal to eliminate fossil fuel infrastructure across campus and exceed NYC’s Local Law 97 greenhouse gas emissions requirements.
• Documentation accuracy helped reduce design risk, change orders, and manual measurement errors.
• The TruView virtual tour helped reduce site visits in sensitive healthcare and occupied academic spaces.
• 2-6mm accurate hospital BIM modeling and as-builts helped advance design decisions, reduce RFIs, and improve stakeholder collaboration.
• SiteMap^® (patent pending), GPRS’ cloud-based infrastructure management platform, can secure the BIM model and digital as-builts to support future renovations, asset management, and long-term campus planning.
• The project team executed NYC’s first fossil fuel-free university research facility.
• Columbia gained digital as-built records to support future healthcare facility renovations and ongoing asset management.
