External condition report

Perhaps as a result of our request during the visit of Chuka Umunna MP to the estate, the council has carried out an inspection to see what work is required to renovate the external elements of the buildings. The report can be downloaded here.

The report says that the following work is necessary:

  • Total replacement of the roofs.
  • Replacement of windows, including patio/balcony doors.
  • Upgrading of doors to flats to meet fire safety standards.
  • Repairs to balconies, “including timber replacement and replacement or alternative glazing”.

This work, together with the necessary structural repairs, is estimated to cost in the region of ¬£10.5 million. We have been told that this work will form part of Lambeth’s capital works programme over several years, starting in the 2019-2020 budgetary year.

Structural inspection report

We have been provided with a report on a structural inspection that was carried out on 31st May and 1st June 2018. The inspection was made by structural engineers employed by Lambeth Council. It makes a number of interesting observations:

  • Lack of routine maintenance, including painting timber cladding, repairing minor cracks in masonry and replacing damaged windows and glass panels on the balconies.
  • Water ingress in concrete structural elements (lintels and floor slabs) leading to pieces of concrete falling from heights, leading to “health & safety risks to the residents and visitors to the buildings.”
  • “A system of tree management should be set up and put in place to manage the trees in the estate in consultation with Lambeth’s Trees Section.” This comment will come as a surprise to service charge payers who are regularly charged significant sums for tree maintenance.

Despite the reported immediate risks from falling pieces of concrete, the council chose not to inform residents until their letter about initial works to make the concrete safe in mid-July.

The report asserts that “None of the defects mentioned above is considered as impairing the structural stability and integrity of the buildings at present.” However, since the inspection excluded the garages, above which many of the flats are built, PRERA has requested that the garages are also inspected.

Concrete works

As we have recently heard, there is a problem with some of the concrete that is present in the flats. Corrosion of the steel inside has caused flakes of concrete to fall from the surface of the concrete. This is an obvious safety hazard and we are glad to hear that the council is now going to carry out works to make the concrete safe. Notices about the works have just appeared around the estate – see below.

PRERA will continue to press the council for details of plans to carry out repairs to the surface of the concrete and to carry out preventative maintenance that will reduce the penetration of water into the concrete.

Hazards around the estate – falling concrete

The committee has been informed of a hazard on the estate that we weren’t previously aware of – falling concrete. This can be added to the list of hazards that includes sheets of glass falling from the balconies, holes in the ground and disintegrating wooden and PVC boxing.

Apparently, the reinforcing rods within the concrete slabs in the blocks of flats are corroding, causing flakes of concrete to fall down. Please be aware of this hazard and do not spend time standing under such concrete lintels and balconies.

PRERA has asked the council when repair work will be carried out to this and other long-standing maintenance issues. We also asked how and when residents would be informed of health and safety hazards that had been identified by the council.
