Ada officials continued moving forward Monday with plans to rebuild the 14th Street bridge.
The Ada City Council voted 4-0 to approve two contracts related to the project. Councilman Bryan Morris was absent.
The first contract was with the Ohio-based engineering firm Burgess and Niple, which will provide construction management services for the project. The second contract was with the Tulsa-based firm Dewberry Engineers Inc., which will supply onsite management services for the project.
Burgess and Niple’s services will include reviewing various aspects of the new bridge, assisting officials in preparing change orders and updating plans as necessary. The city will pay Burgess and Niple approximately $28,000 for its work. The fee may be adjusted if the city changes the scope or extent of work or revises the construction schedule.
Dewberry Engineers will receive approximately $17,780 for its services, which will include weekly site visits, reviews of construction documents and special inspections if necessary.
The city is reconstructing the 14th Street bridge after discovering that some of its concrete had deteriorated. The underside of the deck is in good condition, but the problem is with the top section.
The Oklahoma City-based construction company Haskell Lemon was recently hired to rebuild the bridge deck for about $528,895, which includes repairing the deck and covering and painting the bridge.
Typically, engineering firms designing a certain project also provide construction management, said City Engineer Gary Kinder. In this case, that would require Burgess and Niple to send a bridge specialist to Ada to inspect the bridge during construction.
“Well, they’re in Columbus, Ohio,” Kinder said. “It’s pretty expensive to come down here every week, every two weeks to look at this bridge.”
He said Dewberry is much closer to Ada and has expertise in bridges, so it will serve as the city’s eyes and ears on the project. He added that Dewberry staffers will visit Ada periodically to inspect the bridge, and another local inspector will check the project’s daily progress.
Kinder said hiring Dewberry in addition to Burgess and Niple would make it easier to spot any problems during construction, and it would help the city hold costs down.
“That way, we don’t have to have Burgess and Niple’s expert fly down here, stay overnight or a couple of nights in a hotel room,” he said. “It’ll save us money.”
Councilman Preston Draper asked Kinder why the city had chosen an out-of-state firm to provide construction management services for the project.
Kinder said Oklahoma Department of Transportation officials had worked with Burgess and Niple before, and they suggested that the company would be suitable for the Ada project.
“They came out and they saw our bridge, and they said, ‘You know, we’ve had good luck with Burgess and Niple, and we recommend them,’” he said.
