Bridge Answer Man: Getting the timing right on the big project

We on the Grand Avenue bridge team are often asked: How do you manage a $125.6 million infrastructure project? For the bridge project, there are several tiers of construction management from the executive level to the project management level to the day-to-day management of the project.

Meet Nate Callaway, a project engineer for the Granite RLW Joint Venture on the Grand Avenue Bridge project. Nate’s main role is coordinating and scheduling with the superintendents, subcontractors and suppliers that are involved in the structural work of the project.

Scheduling for a project of this magnitude is a difficult feat. Nate works closely with the GAB construction manager, superintendents and subcontractors to ensure the project stays on schedule. With construction activities at Interstate 70 Exit 114, Exit 116, Seventh Street and Eighth Street, it is a full-time job to ensure all materials arrive on time and everyone has what they need to perform their tasks.

In a normal two-week period, he constantly coordinates the timely delivery of materials to the job site. He is also responsible for submitting all material documentation to the Colorado Department of Transportation so the joint venture can be paid. Nate also records, tracks and forecasts the cost and production rates of all the items needed for the project.

In addition to managing the back-end administrative side of a huge construction budget, Nate spends several hours per week on the job site. He frequently meets on site with inspectors to resolve constructability issues and look for upcoming complications.

Nate also approves modes of handling traffic or MHTs (also known as traffic control). MHTs are used for detours, traffic pattern changes and scheduling flaggers in construction-heavy areas. The MHT is the final document used to put the traffic control plan in place, helping motorists safely navigate their way through a construction zone.

Nate makes sure that day-to-day tasks are complete. He is also the human resources representative for the contractor on the GAB project. His duties include interviewing, hiring, initial employee paperwork and job site orientation with the project safety manager.

Nate lives in New Castle with his wife, Kandis. Before joining the bridge project, Nate worked on the Brush Creek Bridge in Eagle; the Pea Island Bridge replacement in Outer Banks, North Carolina; and did structural design work on a copper mine facility in Bozshakol, Kazakhstan. Nate earned a civil engineering degree from the University of Utah.
