AECOM Tishman Saves 18% Construction Schedule
Tishman Saves 18 moths and Upward of 8 Million in reality Capture
When JP Morgan Chase relocates its Global Headquarters, you know its not going to be easy. While maintaining full time operational continuity, construction logistics became increasingly complex.
Aecom Tishman was to perform one of the worlds most complicated retrofits we have ever seen. They were challenged by the entrenched and archaic system of undocumented, conflicting, inaccurate existing conditions information.
We hear this struggle, every day, again and again, and it it always boils down to the same exact problem:
" We need an accurate Digital Twin of the new facility as soon as possible. "
Enter IPX
Project Background
Innacurate as-built documentation stalls the entire building lifecycle
158,000+ sq ft dense-MEPF
17 Floors - Architectural & Mechanical systems digitized
Fast Track Delivery
AECOM Tishman (ATS, Tishman) is one of the most celebrated global construction firms in the world. Boasting 125 years and 900 million square feet of development as they reshape our city skylines. of experience.
However, Tishman still had blistering memories of project frictions as they were awarded the new contract. They were to lead one of the largest major renovation projects this side of the Atlantic, for the one of the worlds highest profile financial institution w/ an expectation of flawless deliver.
The stakes were HIGH
Tishman’s Project Management Team needed to ensure they had a solid data foundation for the rest of the project stake holders to build upon.

The Challenge
Complex MEP systems create uncertainty before demolition
Renovating a high-rise in NYC, is never simple, but at 383 Madison Avenue, the stakes were even higher. The building’s dense, layered mechanical systems posed a major challenge. Any inaccuracies in documentation could lead to costly clashes, structural risks, or delays that ripple through the entire renovation timeline.
Key Challenges:
No reliable as-builts: Incomplete documentation made it impossible to plan for structural or MEP obstacles.
Dense mechanical systems complicate the renovation: More than 9 layers of complex MEP piping, conduit ducts and hangers.
Security constraints limited scanning windows: Each session needed advance clearance, and re-scans were logistically difficult.
Fast-track schedule demanded immediate data: AECOM Tishman couldn’t afford to wait weeks for a final model—they needed actionable insights as quickly as possible.
With 40-foot double height ceilings on the mechanical floors there were up to 25 layers of conduits, racks and piping ducts and equipment, 383 Madison required a non-traditional 3D scanning approach. The SCANIT technicians used a NavVis VLX3 and a SLAM-based handheld scanner on the ground, and an Elios drone-based LiDAR scanner in the air. These were tied together with a hover map and control points and Matter port 360 Degree Virtual photographic panoramas.

The Solution
SCANIT Fast-Track-Delivery Shaved Months Off the Schedule
Fast Track Delivery ensures teams get the most critical BIM data as soon as it’s possible. Traditional Scan to BIM solutions will wait for the entire building to be modeled before delivering to the client, if that were the case for this project the client would not have seen anything for a whopping 4 months. By working in parallel threads IPX started delivering assets to Aecom in less than 3 days after starting the project. This was achieved by splitting up both floors and areas as well as scopes in a sequenced delivery of assets across the project schedule.
For every floor IPX delivered the following phased deliverables.
Phase | Key Deliverables |
|---|---|
Phase 1 | 2 days after each of the 40 scans IPX delivered Levels and Grids Models and Virtual tours. |
Phase 2 | Architecture & Site → Delivered ahead of full MEP scans to enable early planning. |
Phase 3 | MEP→ Integrated over multiple submissions to prevent bottlenecks. |
Phase 4 | Furniture & Equipment → Final layouts provided while earlier phases were already in use. |
The Results
Eliminating Uncertainty
Integrated Projects federated 40 scans from 4 different devices across seventeen different floors into a unified, millimeter-accurate BIM. By leveraging SCANIT’s rapid digitization and sequenced delivery, AECOM Tishman and JP Morgan Chase:
Shortened the Critical Path of design and construction decisions by months
Virtually performed construction sequencing that allowed for preplanning and reduction of surprises in the field
Optimized scan execution, avoiding repeat scans and disruption to occupants.
For AECOM Tishman, this wasn’t just about accuracy—it was about ensuring the project never lost momentum. With SCANIT, Tishman had full confidence in construction logistics all without even stepping foot on-site.
" We couldn’t afford to wait for a full BIM model before starting coordination. SCANIT’s Fast Track Delivery gave us exactly what we needed, when we needed it, giving us back valuable time. "
