After a brief pause in work while the river barrier was replaced, demolition activity resumed. Workers opened the filled silo, spilling a large pile of material on the back side of the building. Multiple large sprayers were positioned to control the resulting dust.

The river barrier in front of the Silos is intended to block debris off the site from floating downstream. Around 11:30 this morning, the barrier itself broke loose and drifted off.

CDPH blessed a new dust mitigation plan on October 7, according to their website, allowing demolition to resume the next day. While the new plan offers very specific instructions for dealing with dust, it does not address debris in the river.

CDPH and the demolition team meet onsite, we assume for purposes of making a new dust plan. While no further demolition occurs today, crews continue to clean up near the silos.

CDPH stopped demolition due to excessive dust, requiring that demolition contractor Heneghan Wrecking make a new plan to control dust for the remaining portions of the Silos.

The remains of the filled silo are removed, leaving only 2 silos and the tower standing.

Drone footage shows that the holes in the dock are larger than the previous week. The Chicago Department of Buildings (DOB) says that it was not possible to put the promised metal plates on the dock because moving something so heavy onto that portion of the site posed dangerous conditions for workers.

Crews open the 3rd to last silo, finding it filled with the same substance as the other full silo, plus some unknown black material coating the bottom of the interior.

According to the demolition plan, there should be metal plates over the dock and between the dock and the barge. Those plates are intended to prevent dust from going through the planks into the water. As shown clearly in these images, no such protections are actually present.

According to the US Army Corps of Engineers, work has slowed down because the concrete used in this structure is harder to break apart than that used in the other buildings. This contradicts claims by the owners that the Silos were inherently unstable and unsafe.

Work on the Silos has been slow this week. One silo is filled with an unknown substance, and dozens of trucks are circulating to move it offsite. The weather was particularly windy, which posed additional challenges to keeping dust down. Cracks in the wall facing the river are slightly larger, but not substantially changed.

A slice of the silo at the southeastern edge is missing, and cracks appear in the wall directly on the riverfront. Now that barges have left the Santa Fe Slip, bricks and debris in the outlets under the former red brick building are visible. Dead fish from the previous week’s combined sewer overflow have been removed.

The row of silos facing away from the river is demolished. Several small trees cling to the top of the remaining structure.

Las bolas de demolición se ponen a trabajar en los silos de la orilla del río, el último de los 5 edificios del emplazamiento.

Los ladrillos se agrupan para su almacenamiento y las máquinas desmenuzan la carcasa del silo central. Mientras tanto, se colocan grúas alrededor de los silos restantes en la orilla del río para preparar su demolición.

El Cuerpo de Ingenieros del Ejército de los EE.UU. (USACE) realizó una visita a las obras para investigar el tratamiento de los ladrillos -que se supone se guardarán para una futura pasarela fluvial- y la conservación del edificio de ladrillo rojo bajo rasante, requisito para el permiso federal de demolición.

Algunos ladrillos habían caído al río, lo que también era un problema.

Los documentos del USACE muestran lo que se abordó durante la visita.

Imágenes tomadas por drones durante el fin de semana muestran el lugar parcialmente limpio. La Torre Sears es ahora claramente visible desde el puente de Damen Ave y la calle 29.

El edificio de ladrillo rojo está totalmente derruido. Las máquinas recogen ladrillos y escombros. Algunos empaquetan ladrillos para su conservación. Grúas preparadas para destruir el último silo.

El silo central ha quedado reducido a escombros. Se había prometido contenerlo en la parte subterránea de la estructura, pero se desparrama por el suelo. Mientras tanto, el edificio de ladrillo rojo está siendo desmantelado, y los ladrillos están esparcidos por la orilla del río.

El silo central queda reducido a su núcleo. La vista del horizonte desde McKinley Park cambia para siempre.
