Work progress – Liverpool UNO82

July – August, 2022

Drilling and anchoring of piles of different diameters

August – September, 2022

During week 10 corresponding to the month of September, work was carried out to clean up the sludge from the previous excavation; the material was hauled by backhoes which transported the sludge to dump trucks which took it away.

During the week, work continued on cleaning up the mud resulting from the previous foundation processes, and the images show it being hauled away by backhoes and dump trucks.

After cleaning up the mud on the site, the drill cans were also removed by back hoes, which were then taken by dump trucks to their destination.

September – October, 2022

After grading, backhoes were required to begin excavation about the established cut levels. To complete this process, dump trucks were required to remove the remains of the excavation.

Excavation work continued with machinery and transportation of waste in dump trucks.

After a certain stage of the excavation, the slopes required for the correct functioning of the bank are shaped, since it was considered that the properties of the soil in which it is located are poor instability.

At this stage, work has continued by hauling mud and soil from the deep excavation with the backhoes; the mud is transported by dump trucks.

The layout, excavation and cleaning of the excavation process iscompleted, making the bank route clear.

November – December, 2022

On week 17, corresponding to the month of November, preparation of the land is being done as well as the filling of the floor with 4” graven.

The poor concrete template is placed f’c=150 dried for 3 days with a thickness of 10 cm. / To later receive the assembly of the slabs and grade beams.

The images show the template finished up to the Q axis. Leveling will continue in stage 2 along with the compression of the rest of the ground.

In week 18 corresponding to the month of November, work is being done on the demolition of pile capping.

We continue with the assembly of stirrups for dice and grade beams. / Pile rod bends according to leveling for preparing the assembly of dice and grade beams.

We begin the excavation of the adjoining missing sides of the middle of the field.

During the excavation process, we continue with the extractions of mud resulting from the process. Mud is carried out with the backhoe and loaded into trucks.
