Being involved in a large social housing tower block refurbishment project where 90% is going to be LA social housing and 10% remains in private hands a multiagency approach was taken, issues affecting common parts (front doors, alarms in flats as part of a common full evac policy if adopted, external cladding, filling in of redundant common heating ducting penetrating slab floors between flats) would be enforced by the FRS if the RP didn't deal with these, the RP in turn asked the LA Housing to carry out HHSRS enforcement visits of the private flats (where the RP couldn't do these works themselves) and is issuing Improvement Notices to get the front doors changed, ducting filled, detection fitted and any other high risk items found (even if not relevant to the common parts)
Reference will be made to the current standards in notices.
The standard change caused a hiccup, the work started before Pt 6:2019 and so only Grade D was specified for flat devices and a crate of hundreds of alarms were bought, but they were removable battery back up. The new part 6 differentiates between removable and sealed back up power and for this site would require D1 (sealed) but those installed and bought to be installed were D2. Arguably as the project spec predated the change then it's not retrospective but stakeholders not unreasonably questioned if it would be better to change them all. It was agreed due to the planned management set up in the property with daily and weekly flat checks the risk of prolonged alarm defeat was deemed low so the D2 kit install will be completed.
