Concrete Street Reconstruction

Project Summary
Many of our older concrete streets consist of 5" of concrete on top of compacted soil. Due to the extensive failures of the existing pavement, the concrete street and underlying soil will be removed, and a new cross-section will be constructed, consisting of 4" of rock and 8" of concrete.  Slabs will be tied together using epoxy-coated steel rebars. 

Please note that neither the existing nor new concrete is "colored" concrete.  While there is some limestone-based concrete around the city, most of the concrete contains Meramec sand and gravel, which provides the orange/brown look.  While the new concrete initially appears to be a bright white, over time, the color mellows and the top layer of cement wears off, revealing the brown sand and gravel underneath.
The 2019 project will include three streets in Berkley Manor: Berkley Manor Drive, Federal Drive, and Wedgeton Lane. Bids were opened 2/22/19, with E. Meier Contracting the low bidder. 


Project Location and Schedule
Phase 1-Work started June 4th with Federal Drive from Wendover to Dunmorr. Pouring of concrete started Wednesday 6/12, but they had to quit early due to rain. The rest of the north side was poured the following two days. Pouring of the south side was further delayed due to problems with rain and groundwater from neighboring properties.
 
Phase 2-Removals started on Tuesday 6/12 for Berkley Manor Drive from Camberly to Bopp. The south side was poured 6/26 and the north side was poured 7/2, then reopened a week later.

Phase 3-Work on Wedgeton started the week of July 8th, with the removal and replacement of the south side of the streetThe north side will be replaced the week of 7/22.

Phase 4-Work on Berkley Manor Drive from Candlewick to Camberly is currently underway.  The north side was poured on 7/16 and 7/17 and will need to cure one week before it can be reopened to traffic

Phase 5-Federal from Ballas to Wendover is scheduled to start in early August, upon completion of Wedgeton.

Starting with Phase 3, each street will be replaced one lane at a time.
The wet conditions this year have made it difficult to complete the project as planned.  By removing and replacing the full width of each block, we had hoped to reduce the time to complete each phase. However, that required driving on the prepared subgrade (4” of rock on dirt).  In normal years, this wouldn’t be a problem.  We could drive trucks on the subgrade and place rebar baskets as the truck pulled forward.  This year, the trucks driving over the subgrade are creating ruts, because the underlying soil is so wet. With both Federal and Berkley Manor Drive, we’ve had to wait a week after pouring for the first side to cure, then drive the concrete trucks on the new pavement to pour the second side.  This delayed us by the week we would’ve gained by doing the full width all at once.

DURING WORK, PLEASE TURN OFF SPRINKLERS AND DIRECT SUMP PUMPS, POOL DRAINS, AND OTHER DRAINS AWAY FROM THE STREET.  THESE CAUSED REPEATED DELAYS ON PHASE 1, SOFTENING THE SOIL AND WASHING AWAY THE ROCK.
