Introduction
In April of 2020, JF White Contracting Company, a subsidiary of Dragados USA, decided to respond to an RFP for a multi-million dollar Massachusetts DOT design-build contract.The project in question consisted of the replacement of four sets of bridges along a four-mile section of Interstate 90, also known as The Massachusetts Turnpike. This seemingly straightforward task was made more complex by the requirements to maintain normal traffic flow on weekdays, and interrupt toll collections as little as possible. Due to this need, MassDOT would only allow construction and lane closures to take place on weekends between Friday at 9:00 pm and Monday at 5:00 am.
A Solution in the Nick of Time
Jack Pecora and Rob Collari of JF White turned to RDV Systems, a provider of cloud-based 3D visualization technologies and services. They had engaged RDV on a previous construction project to provide visualizations used for public involvement, and had confidence that RDV could deliver quality products within the deadlines.
RDV embarked on two parallel visualization efforts. The first was a “4D” video showing the construction process for one bridge over a single weekend. The second was the development of a 3D project model of the entire site showing the order of operations and traffic diversions over eight consecutive weekends. Within a few weeks, RDV developed both the 4D video and a complete interactive 3D Project Model of the entire project. Images from the model and the 4D video were included in JF White’s proposal.

The 3D virtual model was used to create a “storyboard” video that showed the various stages of JF White’s plan over the course of the entire project. The model included multiple view states showing traffic flow and construction stages for each of the eight weekends. The storyboard video stepped through each weekend in sequence, showing how and where traffic diversions would occur and which bridges were being worked on. This video was able to show the entire scope of JF White’s plan, and clearly conveyed how they would implement construction and maintain traffic given the complicated variables.

The Win
The visualization materials were key in communicating JF White’s complex solution, and were a deciding factor in their proposal receiving the highest technical score. RDV was able to deliver high quality and compelling visualization within the tight deadline required. Shortly after their successful proposal meeting, JF White was announced as the winner of the project bid, with a proposal cost of 49 million dollars.
We were going through a dry spell, and we needed this win. We couldn’t afford to have our proposal be misunderstood due to inadequate visual assets. RDV’s video simulation was the best way to communicate our plan
After having won the bid, JF White can now utilize the RDV project model to conduct design review, compare alternatives and updates, and create new visual assets when engaging with the public and other stakeholders. The communicative visuals that assisted JF White in winning the project bid will serve as a living document as they continue to develop and implement their plan.
