Location:Hemel Hempstead, Hertfordshire
Chenies is a Met Office radar station located near Hemel Hempstead in Hertfordshire. On site there is a 12 metre high circular concrete tower with a concrete ring at the top housing the radar and covering dome.
The scope of works for LARS was to replace the internal vertical ladder with a circular steel staircase with rest platforms, leading to a new inclined ladder and sliding interlock hatch to access the radar dome.
Concrete repairs were also required to the outside top face and edge of the concrete ring at 12 metres and to fabricate and fix a new steel ring to the top of the concrete section of the structure.
