The Pit As Seen From Grade

On June 2, 2016, this photo was taken of the construction site before there was an actual pit. Actually, it was the construction site with a large bank
on the left, which meets the southern grade of the project. It is from this section of the site that cutting back of the soil will begin. Once the H-beam
soldier pilings are exposed, construction of and the anchoring of the shotcrete shoring walls will begin.

Work begins by first clearing the site and removing the rubble.

A scraper strips and moves dirt around to level the site for a temporary asphalt parking lot.

The construction site is being prepared for the May 29, 2016, official groundbreaking ceremonies. The freshly laid asphalt is where the main event
will be held. Just to the  right, out of camera range, a number of vendor tents will be set up to accommodate the visitors.

The next day following the groundbreaking ceremonies, holes, 75 ft deep, were drilled into the soil where soldier piles were lowered
and cemented into place. The soldier piles would be sunk around the whole perimeter of the site before the excavation of the pit could begin.

The south bench approximately fifteen feet above where the dump truck is parked reveals the first tier cutback. Each tier will be six-feet tall. The
south shoring wall will include seven tiers. The north shoring will have 5 tiers. Because of the 15 foot slope between the south shoring wall and
the north wall, the average permanent grade depth will be approximately 36 below top grade.

By June 6, 2016, when this photo was taken, the cutback of the first shoring wall tier continues to move the west. Even as the first tier cutback
is being prepared for, tiebacks, the drain mats, rebar, and the shotcrete, the drill and crane continue to advance slowly around the perimeter of the site.

When this photo was taken, the soldier piles had been lowered on the south, west, and three-quarters of the north perimeter.

With the installation of the soldier pilings completed along the northern perimeter by the afternoon of July 12, 2016, work will begin the next day
on the eastern boundary.

This photo taken from within the pit reveals the first cutbacks on the north and eastern walls.

From the northeast corner of the construction site, one can clearly see the activity down in the pit. A view of the north wall (right) is being prepared
for shotcrete. The actual height of the first tier can be judged by the measure of the man standing next to the wall.

Under cloudy afternoon skies on October 28, 2016, heavy equipment is cutting back the last tier and compacting the soil on the west and north
shoring walls.

The pit as viewed from the west wall on November 10,2016. In the foreground a trench is being dug to lay many telecom ducts. The
trench is approximately five and a half feet deep by six feet wide. The cement truck is pouring slurry over ducting in an electrical  trench.
Note the last shoring wall five and a half feet deep by six feet wide. With the application to these last sections, the shoring walls will be completed from
grade to the bottom of the pit.

The final round of shot crete was applied to the last tier of the south wall(note the darker color) on or about November 13, 2016.
With this application, the shoring walls are complete around the perimeter of the construction pit. All equipment rests on permanent grade. The two
caissons to the right have been capped by cardboard sleeve, which will be temporarily filled with sand to prevent corrosion of the rebar. A few days
before Thanksgiving 2016, the dirt ramp (located to the left out of view) will be moved to the right (north) and will cover the caissons until the ramp
is removed. The ramp must be removed before the four (4) inch mat is poured over the bottom of the pit.

As the afternoon sun gradually envelopes the pit, cement trucks continue to apply slurry to the bottom of recently dug trenches.

The lengthening shadows (previous photo) gave way to this nightscape (November 17, 2016).
