The Week of July 22, 2019 — Four Pits, a Tunnel, and to Wet Your Appetite an Update on the Kitchens Too

The featured image for this post is of the north elevation of the Adult Hospital tower as viewed from Taylor Court. Upon completion of the project, the main entrance to the hospital will be widened and will loop around behind the flag poles and in front of where the white tarps are hanging. This area is known as the galleria and main entrance canopy.

Upon arriving at the site today (Monday, July 22, 2019), I was informed that Wednesday of this week, work would commence on a new pit near the southwest end of the building. This pit will hold a large “fire water” reserve tank, which can be used during a fire in the building.

Work continues to progress on the southeast pit, which holds four domestic water tanks to be used in an emergency. Gravel now covers the tanks and the gravel is being covered with black insulation.

In the bottom of the elevator pit, rod busters are positioning and securing the rebar in preparation for concrete to be poured on Friday of this week.

The big machines were working at the Taylor Street emergency generator site. On the west side of the site, an excavator was digging a trench for sewer pipes. A representative from the gas company was on hand in case there was an emergency.

Down in the deep trench on the west side of the building, I found a number of rod busters hard at work. They were scrambling to finish securing wire mesh to the remaining exposed dirt sides of the trench before the concrete truck arrived at noon.

In the meantime, while the big machines continued their mechanical drumbeat down at grade, men from Tower Glass perched high on a hanging platform were sealing windows some fourteen floors above.

Wow! What a Difference a Year Makes!

A Testament to What Men and Machines can Accomplish!

Four days shy of a year ago, the project was in the steel phase and had just topped out at the podium level. A few columns had been set for the adult tower. The steel structure was approximately six-stories shy of cresting the height of the iconic clover-leaf towers. Today, the new adult hospital tower dwarfs the existing Medical Center.

The Domestic Water Pit — Update

The laborers begin to cover the gravel with insulation. The same insulation comes up along the four sides and is folded in over the gravel. In the end, the tanks will be sealed in an insulated envelope.

The two laborers at the right are connecting an elbow to which an outflow pipe (going to the building) will be connected. The inset image is a closer view of the elbow.
What a difference a day makes! When I arrived on site today (07.23.19), the steel pilings along with the steel shoring plates were being pulled out. The west side of the pit had been completed with the sides terraced and the crew was working on the south side.

The piling is fully extracted.
Three sides of the steel-plated shoring walls have been extracted and the side walls have been terraced and sloped to meet OSHA rules. Not all of the insulation has been laid over the tanks as not all of the piping has been completed.
The next day they west bench began to be graded to decrease the slope into the pit area.
I made my way down into the pit area and took this image standing in the southeast corner of the pit.
With the low spots over the tanks almost leveled, the last covering of TenCate Geosynthetics separation barrier is being pulled over the gravel.

The “Fire Water” Pit – – New

The outlined area is the approximate location where the “fire water” pit will be dug.
As the pilings are extracted from around the domestic water pit, they are laid out near where the southwest “firewater” pit will be excavated.
The steel shoring plates are stacked near the excavation site.
During the day (July 24, 2019), the “firewater” is in the process of being laid out and the CAT Telescopic Leader Mobilram system was staged.

By mid-afternoon drilling had begun for the piling holes.

The Schuman Pavilion Bridge Elevator Pit — Update

At the same time work continues on the Schuman Pavilion Elevator pit, another team erects the columns that will support the steel span that connects the new hospital to the Schuman Pavilion elevator tower. In this image, the south support columns are shown in the rebar stage.
The north support columns are in the forming process.

The rodbusters begin to lay rebar in the bottom of the elevator pit.
The following day the rodbusters continue to lay rebar.

The following day, the rodbusters and surveyors will still at it in the elevator pit. From the previous day, the sump had been formed.
This image was taken a few hours after the concrete pour. After the concrete cures, the carpenters will begin forming the sides.
The forms for the columns of the Schuman Pavilion north pedestrian bridge were also filled with concrete earlier in the day.

The Taylor Street Backup Generator Pit — Update

The Tunnel Trench Excavation — Update

Rod busters hang steel mesh at the bottom of the trench in which the tunnel will be constructed.

The following day, the shoring wall is

At last, the boarded-up tunnel access opening is being punched through as the retaining boards are slowly and carefully being removed exposing the other side of the foundation into level “A.”
Working in 103-degree temperature, a laborer works at dislodging another retaining board between two pilings.

The following day, the opening was larger. On the other side, a crew is hanging mesh in preparation for a concrete pour at 11:00 AM.

And the Kitchens Too — Update
