Case Studies

Jodrell Bank

The works involved the cleaning and preparation of areas of the Lovell Telescope The works involved the redecoration of the rotor assemblies to the red tower only.

The Works involved jet washing and preparation of the area, rub down and abrade of loose paint and spot rust, Spot prime areas, full patch prime coat, intermediate coat and a full finish coat as per the specification.

Additionally the project involved specialist steel work repairs and replacements to structural steelwork. To undertake this we had to liaise with the structural engineer and prop sections of the telescope. This element of works involved cutting out delaminated steels & re-bolting new.

Due to the tight time scales MBC were instructed to work nights to ensure that the telescope could be put back in use to view a supernova which only can be viewed once every 45 years therefore completing on time was critical to the scheme.

For this particular scheme we had to erect a bespoke scaffolding. Our contracts manager Tom Bunting assumed the role of temporary works co-ordinator.

The picture to the right shows the scaffolding during construction. The scaffolding consisted of 10 lifts to get the all sections of the rotary blade and was braced off the structural steels. We had to have a design undertaken. This was then sent to the structural engineer who checked the point loads where the scaffold would be braced off the steel.

When erecting the scaffolding we used a mechanical winch to lift the scaffold poles 73ft to the structure. Particular car had to be adhered to because Jodrell Bank is now classed as a world heritage site.

During the works we also received an instruction to construct a scaffolding between the 1957 dish and the new dish. This was high risk ticket item in that we 1957 dish was not only grade 1 listed but also in a state of disrepair. To undertake this we had to undertake a bespoke design an send this to an engineer to spread the loads of the scaffold (design outlined below) because the dish was supported on steels which were nominal in size we had to employ a specialist rope access team to measure steels and draw up a condition survey so the structural engineer could asatain what loads the steel could take, we then had to indicate the dead load and point loads of the scaffold and design our scaffold to spread the load over the dish.
