Booster Pumps are Needed

As MamaJo moves further away from her starting point near Dwenger and Glasgow Avenue, booster pumps are needed to keep the slurry lines operating for the tunneling process.   That meant some down time this week as she sits just south of Taylor. But work still progressed at the drop shaft locations.

Below at drop shaft #1 (Foster Park) you see on the left where crews have set forms. The photo on the right shows the walls looking upward. Week of Jan 25-29, 2021.

Below crews at drop shaft drop shaft 3 (Brown Street) had icecicles and in 2nd row left they installed heat items. On the second row – Right- is drop shaft 5 (Thieme Drive) where crews placed rebar for the diversion structure slab. Week of Jan 25-29, 2021.
