The Week of October 22, 2018 — Work Continues on Floors 13 and 14, and Hanging Prefab Curtain Walls (GFRC) Continues

This week, the ironworkers will work their way east, from the central elevator towers, hanging steel on the 13th and 14th floors of the Adult Hospital tower. It is my understanding that the subcontractor that hangs the prefab curtain walls will be on site to begin hanging the walls on the north side of the structure.

We have a new abbreviation to add to our construction lexicon. Heretofore, I have been referring to the cladding of the steel skeleton as Prefab Curtain Walls. Technically that is true, but the abbreviation GFRC or Glass Fiber Reinforced Concrete has been tossed around on site. So this abbreviation will be used interchangeably with cladding, and prefab curtain wall.

Another First — Two Glass Panels Were Installed on the Second Floor 

I had to take a second look: There, up on the second floor were two glass window panes from which one could see the main entrance to the Medical Center, Schuman Pavilion, the dental school parking lot and Taylor Court. No doubt an installation test by the subcontractor.

The first glass panel from which a photo was taken through.

Hanging the Prefab Curtain Wall Begins

Night Shots From Webcam 2 and 5

By 6:08 PM, the first flatbed truck arrives with three sections of the curtain wall.

Sections of the north side of the building are bathed in lights to provide better visibility in hanging the curtain wall panels.

The first panel to be set has been tilted up on the transport truck (circle) and is being readied to be hoisted  into position by the crane.

The first panel (circle) is whisked high above the structure on its way to be lowered on the northwest side.

Hanging the GFRC on the Steel Skeleton Continues —

As Photographed From the Site

No more screen shots (at least for awhile) to document the construction activity. Back on site to photograph more of the night installation of the prefab curtain wall on the north side of the structure.  It is my understanding that this process will continue Monday – Thursday nights for the foreseeable future.

Under the Wednesday night lights: Flags, a full moon, and prefab curtain walls. A great night to photograph the hanging of some skin on the steel skeleton.

As it hangs low in the eastern sky, the full moon seemingly projects its light on the northwest section of the curtain wall.

As it sinks in the western sky over Loma Linda University Medical Center, approximately twelve hours after the previous photo was taken, the full moon slowly threads its way between the crane’s boom (right) and the north side of the adult tower (left).

A panel for the third and fourth floors hangs upright as a tether is attached before the panel is hoisted into place.

Up, up and Away — A panel is whisked in the air before it is lowered into place.

Activity on Level ‘A’

The Mechanical Room: Pipes, Pipe, and More Pipes

Mechanical Pipes: Large Pipes, Small Pipes, Copper Pipes, Galvanized Pipes, Ridged Pipes, and Flex Pipes. Pipes for Industrial Hot Water, Industrial Chilled Water, Domestic Cold Water, Domestic Hot Water, Soft Water, Waste Water, Medical Waste, and Runoff Water. Pressurized Pipes.  Then there are Electrical Pipes (conduits) for Various Voltages: Large Pipes, and Small Pipes. Pipes for Low Voltage Equipment, Pipes for Telecommunications, Pipes for Information Technology.

En route to the mechanical room, this warning sign next to an elevator shaft caught my attention. Evidently, periodic testing is done during various stages of the installation.

Two welders intently welding large water pipes.

A large curved pipe with manifolds hangs from the ceiling stirrups.

Another view of the mechanical room. Note all of the hangers of various heights yet to receive pipes.

Oh, the twists and turns of the large pipes in the mechanical room.

Ending the Week on the 12th Floor Decking

Looking out over the 12th floor decking. To the left, the south bays of the 13th and 14th floors of the Adult Hospital Tower rise above the deck. Next week the the columns, beams, girders, and infills be set on the north bays.

Watch your step: A closer look at the 12th floor. Note the ironworker on a 13th floor girder scattering corrugated metal decking.

Another northwest view of the Inland Empire.

Day is done, and the banner hangs in the shadows of the night.

Tomorrow, the banner will catch the gleam of the morning’s first beam.

In all its glory the banner will again reflect shines in the stream;

‘Tis the star-spangled banner! Oh long may it wave

O’er the land of the free and the home of the brave!

God Bless America!*
