• Project Area: 22,561 SF
• Architect: Smith Alvarez Sienkiewycz
• Engineer: N/A
• Contractor(S): BIM Services LLC
• Owner: N/A
• LOD: 400
• Trades Covered: Fire Protection, Shops
• Software: Revit Fabrication 2021
• Verticals: Fire

Challenges and Solutions:

Challenge 1: Ceiling Space Optimization

• Issue:
  • Limited ceiling space necessitated strategic planning for trade hierarchy and efficient utilization.
• Solution:
  • BIM Services prioritized trades requiring access (such as cable trays, valves, dampers) closer to the ceiling, and suggested reroutes for better coordination and value engineering.

Challenge 2: Elevation of Fire Protection (FP) Pipes

• Issue:
  • Critical elevation considerations for FP main pipes to ensure system efficiency and compliance with city regulations.
• Solution:
  • BIM Services proposed optimal elevation and routing of FP mains, avoiding rigorous drops and offsets that could trap water and impact system approval, ensuring maximum efficiency.

• Owner: N/A
  LOD: 400
• Trades Covered: Mechanical, Shop Drawings, Spools Coordination
• Software: Revit Fabrication 2020
• Verticals: Mechanical

Challenges and Solutions:

Challenge 1: Support Details

• Issue:
  • Detailed support system for mechanical pipes required precise coordination and installation.
• Solution:
  • Implemented 3-D simulations and regular on-site visual checks to ensure accurate placement and coordination of supports, addressing the project’s meticulous requirements effectively.

Challenge 2: Simultaneous Coordination and Construction

• Issue:
  • Coordinating as-built conditions while construction progressed on site posed challenges in tracking virtual progress versus actual construction.
• Solution:
  • Established a rigorous schedule and clear communication protocols to manage real-time issues and resolutions. Constantly updated models and provided outputs to the site ensure smooth project execution during the final stages.

• Project Area: 2.8 million-square-foot

• Contractor(S): GC- Whiting Turner and Dimeo Construction Company
• Owner: Amazon
• LOD: 500
• Trades Covered: Electrical, As-Built, Point Cloud
• Software: Revit Fabrication 2023
• Verticals: Electrical

Challenges and Solutions:

Challenge 1: Model Accuracy in a Large-Scale Project

• Issue:
  • Required to create a model twin with a tolerance of just 1″ deviation across a 2.8 million square feet area.
• Solution:
  • Utilized the ‘Cintoo’ platform to integrate field scans for accurate as-built modeling, minimizing manual errors from traditional redline markups. Used Revizto for real-time monitoring and updates to manage project scale effectively.

Challenge 2: Late Integration of MHE and Header Steel Models

• Issue:
  • Models for Material Handling Equipment (MHE) and Header Steel were introduced late, after initial coordination and installation across four levels.
• Solution:
  • Leveraged Revizto for live coordination, enabling immediate visibility of issues and daily updates to accommodate evolving models. Ensured efficient clash coordination considering field conditions, facilitating swift issue identification and resolution.
