Key Terms

engineer of recordtechnical
"Parsons is serving as the engineer of record and the prime design consultant"
The engineer of record is the licensed engineer officially responsible for the design, safety and code compliance of a specific project or piece of equipment, who signs off on the technical documents and permits. For investors, their involvement signals that the technical work has an accountable professional backing its safety and legality—like having a trusted guarantor on a contract—which affects the likelihood of project completion, regulatory approval, potential delays, and liability risk.
prime design consultanttechnical
"Parsons is serving as the engineer of record and the prime design consultant"
A prime design consultant is the lead firm or individual hired to manage and deliver the overall design work for a project, coordinating specialists, schedules and regulatory requirements. For investors, the role matters because the prime consultant often determines whether a project stays on time, on budget and compliant with rules—similar to a conductor keeping an orchestra in sync—so their track record can influence project costs, delays and risk.
program managementtechnical
"applying its global infrastructure design and program management expertise"
Program management is the coordinated oversight of several related projects and ongoing efforts so they deliver a larger business goal, like a conductor keeping multiple sections of an orchestra playing together toward one piece. Investors care because good program management reduces wasted time and money, lowers the risk of delays or messy handoffs, and increases the likelihood that strategic initiatives will produce predictable, measurable financial results.
advanced traffic management systemtechnical
"more than 50 advanced traffic management system deployments that help cities and states"
An advanced traffic management system is a network of sensors, cameras, traffic lights and software that monitors and controls vehicle flow on roads in real time, like an air-traffic controller or orchestra conductor for city streets. Investors care because it can reduce congestion and accidents, lower operating costs, and create steady revenue or service contracts for technology and infrastructure providers, while boosting economic productivity in areas that adopt it.
