Early morning start times are required to pour concrete at the main AWP construction site just north of Santee Lakes.
This means our crews arrive at the site before the sun comes up to pour concrete for the different structures and buildings part of the advanced water purification, water recycling and solids handling facilities.
These pours have been ongoing throughout the past year and as of February 2024, roughly 85 more early morning pours remain.
For a typical pour, several hundred yards of concrete are hauled in by multiple trucks.
For example, during a recent pour, roughly 220 yards were poured on two separate portions of what will be a secondary clarifier structure part of the water recycling facility. An additional 58 yards were poured on the water recycling facility primary clarifiers and 40 more yards on the solids handling facility thickening and dewater building.
“There are a number of factors that go into why the early morning pours are occurring,” said Mark Niemiec, Director of East County AWP. “Temperature is one of them. We want to be able to try to keep that concrete as cool as possible, during and right after the pour occurs. Out here in the East County, temperatures tend to rise throughout the day and to date, most of those early morning concrete pours have started around 3 am with the concrete trucks coming in.”
The cooler conditions prevent heat from evaporating which could leave stress cracks in the concrete. In addition, the early start allows the concrete trucks to avoid major traffic.
“And it’s during these activities that we really appreciate our neighbors’ patience and understanding,” Niemiec added.
Nearly 60% of the concrete required for the project has been poured.
