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 this ain't going to be easy. While maintaining full time operational continuity, construction logistics become 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 to have an accurate Digital Twin of the real world as soon as possible. "

Project Background
Major Renovation of a Financial Power House
158,000+ sq ft of Densely-MEP
17 Floors - Architectural & Mechanical systems digitized
Fast Track Delivery
Key Facts
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 failures and 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 world highest profile financial institution w/ an expectation of Flawless,
Stakes were HIGH
Tishman’s Project Management Team wanted to ensure they had a solid foundation for the rest of the team to build upon, and be confident to use as a foundation.

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.
As one of Manhattan’s most prominent commercial properties, the project was high-security, high-profile, and required a tight 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.
Working within the security restrictions and splitting scanning into 7 separate sessions to accommodate lower traffic times in the building, SCANIT had to digitize 17 floors across seven scanning sessions in just 15 days.
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. Thesee 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 ready, so work can begin immediately, without waiting for the full model. By working in parallel threads IPX drastically increased the speed to value for Tishman. This was achieved by splitting up both floor and areas as well as scopes in a sequenced delivery of assets to the team.
For every scope
Phase | Key Deliverables |
|---|---|
Phase 1 | 2 days after every 40 scans we 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 SCANIT service culminates in a comprehensive 3D model on IPX, the building digitization platform that allows users to visualize, query, measure and share building information in a browser window. This empowers project managers with:
detail and accuracy: The SCANIT service boasts a nationwide network of technicians equipped with LiDAR-grade 3D scanning capability, delivering standardized LOD 200+ models through rigorous in-house QA/QC.
Turnaround times: SCANIT’s technicians have the capacity to digitize hundreds of thousands of sq ft per day at LOA300. Pricing and delivery times are quoted up front, via SCANIT’s easy web order form.
A hub for verified building information: IPX's user-friendly interface facilitates seamless file sharing between architects, engineers, clients, and other stakeholders—no more struggling with Revit licenses to get access.
The Results
Eliminating Uncertainty
Integrated Projects federated seventeen separate scan across 4 different devices into a unified, millimeter-accurate BIM model. By leveraging SCANIT’s rapid digitization and sequenced delivery, AECOM Tishman and JP Morgan Chase achieved:
Shortened critical path to design and construction tasks, with Fast Track Delivery providing early access to critical BIM data.
As-builts with millimeter accuracy, preventing unwelcome surprises in demolition.
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 the data they needed to make informed decisions before breaking ground.
" 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. "
