  • Data Integration of over 100 buildings and 25,000 schedule items

  • Implementation of a platform for construction planning, scheduling and risk management

  • 4D Scheduling Assist providing

  • Client and Community Engagement through web and desktop visualization


Trimble Consulting (TC) worked with the city of New York and project team of projects managers, schedulers and construction experts to develop a comprehensive 4D (BIM + schedule) approach to the coordination of construction activity in lower manhattan after 911. TC created a system for aggregating, visualizing and planning scenarios for the construction of the World Trade Center site and surrounding neighborhoods. The 4D data set was used to quickly model alternatives for complex construction scenarios, allowing stakeholders and experts to design best case strategies. The 4D data set was extended to a web portal that businesses and communities could use to understand construction progress and the impacts of street closures on the operations of the city.

The team was recognized for their application of BIM coupled with an ongoing risk assessment program.

By assembling all of the spatial and logistical data for the multiple projects in a single environment, detailed assessment and planning could be done by all stakeholders. This allowed conflicts between the multiple ongoing project plans to be assessed prior to construction, streamlining the construction of the WTC redevelopment. Detailed alternative scenarios for construction facilitated streamlined construction while minimizing the disruption to subway, traffic and pedestrian flow. The 4D approach was honored with a Celebration of Engineering & Technology Innovation (CETI) Award in 2010 by FIATECH in the category of Scenario-based Project Planning. The team was recognized for their application of business information modeling (BIM) coupled with an ongoing risk management program.
