Aldermen OK change order for Green Park Road bridge

Staff Report

The contractor reconstructing the Green Park Road bridge over Gravois Creek recently encountered “unstable” soil in the creek bed, necessitating a roughly $3,000 change order, according to Green Park City Administrator/City Clerk Zella Pope.

Contractor Concrete Strategies submitted to the Missouri Department of Transportation a $3,061.58 change order request, Pope told the Board of Aldermen, reading an update on the Green Park Road and bridge redevelopment project she received from Mark Payken of Payken Consulting.

Rain earlier this month weakened the soil, a “common occurrence” in bridge projects, Payken wrote. SCI Engineering discovered the issue while conducting required soil testing for the project, Pope added.

“This change order has been forwarded to MoDOT for verbal approval. Once the change order is approved, work will commence on backfill of the box culvert,” Payken wrote.

Workers will replace the bad soil with minus rock, according to Payken.

Work on the new bridge and the redevelopment of a roughly 6,000-foot stretch of Green Park Road from Tesson Ferry Road to Lin Valle Drive began this spring.

L. Krupp Construction Inc., the road project contractor, was scheduled Aug. 17 to begin excavation to construct a new curb and gutter at the Lin Valle end of Green Park Road, Payken wrote.

“Krupp will proceed towards Kohrs (Lane) at which time Missouri-American Water should have completed its work at Kohrs,” he wrote.

Payken initially was hired by the city to perform right-of-way acquisition for the project. His role since has expanded to include project management and the responsibilities a director of public works or city engineer normally would handle.

City Hall has fielded “a lot of calls” from people who are frustrated with the ongoing Green Park Road closure, Pope said.

“But it’s something that is totally unavoidable and I just try to explain to them that the road is closed down by Lin Valle and it will be closed for a while,” she said. “They get upset because nobody’s working at times. Well, it’s because they’re waiting on utilities to do their work so that they can go in there and finish working. Unfortunately, that’s part of construction work …

“Most everybody had been pretty good. I’ve had a couple people come in who aren’t real happy about it, but we just have to live with it until it’s done … Everybody’s going to have these issues the further down they go on Green Park Road; it’s just going to change locations.”
