Scaffolding-cage not fully sealed - R/H side building next to 93 Paul Street

Severe air pollution caused by dust and building materials spilling from skip. Also the scaffold-cage/flume (plastic shield) from the first floor is not fully sealed. The building work continues to cause street air quality problems along with dirt across pavements and surrounding buildings (see photos attached). Contractors are operating seven days a week, on occasion early mornings and late evenings. Skip is replaced several times each week, and has continued for 12-24 months. We understand this work will take another 2 years to be completed (according to the workmen onsite)
