St Chads - Shrewsbury

St Chad's is a major landmark next to Shrewsbury's Quarry Park, it is an iconic Grade I listed circular Georgian church. P.B.S.D were responsible for designing an access scaffold and temporary roof to fully enclose & gain access to the church tower for repair works & urgent restoration to the lead, stonework and cross on the dome. The scaffold design was required to span 11.0m over the porticoes & roofs on all 4 elevations. The beam spans then supported a 30m height of scaffolding with a temporary roof structure on top.

St. Paul's - Seacombe

St Paul's is a Grade II listed church located in Seacombe, Birkenhead. The top 6m section of the spire was taken down as it had become unsafe. P.B.S.D was tasked with designing a full access tower to the church tower to enable the existing spire to be taken down to cornice level and then re-constructing to original height in stone to match. P.B.S.D designed an access scaffold the could only come to the ground on 2 sides and incorporated shear brackets & beam spans. The scaffold also included a loading platform that was capable of supporting a total load of 42tonnes to enable the spire stonework to be stored without bringing it down to the ground.

Porthill Footbridge - Shrewsbury

Port Hill Footbridge, is a suspension bridge for pedestrians crossing the River Severn in Shrewsbury. P.B.S.D were responsible for coming up with a suitable scheme to provide an access & enclosure scaffold for: removing the bridge deck, blasting, repairing & re-painting the steelwork and installing a new timber deck. However the bridge could only be subjected to relatively low imposed loads. This meant that PBSD had to work very closely with the main contractor, L.A. and structural engineers to achieve a scheme that was lightweight but could still offer a full access and enclosure. The solution was to design the scaffold so that the imposed load only occurred at the suspension cable positions. The live load & sheeting were then split into 4 phases to ensure the bridge structure was never overloaded. The scheme was a great success & the bridge was handed back to the L.A. a week early.

Sir John Barrow Monument - Barrow

The lighthouse shaped monument is Ulverston in Cumbria's most recognisable landmark.  Spring 2009 saw the start of repair and restoration to the monument.  No shear ties were used during the erection of the scaffold due to the monument being a listed building.

Liverpool Library - Liverpool

Liverpool Central Library is undergoing a major £50 million pound refurbishment that is due for completion in spring 2012.  All three libaries are to have their roofs re-covered.  In order for these works to be carried out P.B.S.D were responsible for designing the temporary roof and incorporated the Hakitec 750 roofing system in order to achieve the required weather protection.

Althorp House

Althorpe House is a Grade I stately home in Northamptonshire and is the official residence of The Earl and Countess Spencer. From 2009 to 2011 the building underwent a £10m restoration project which involved a programme of re-roofing, stonework replacements and extensive refurbishment of the mathematical tiles, which face much of the house. This required a full external sheeted access scaffold and Temporary roof over the house built in 3 phases over the 2 wings and main house. The scaffold was required to be freestanding due the fragile nature of the tiled façade. This resulted in a complex scaffold design that required over 40tonnes of kentledge to support the 30m temporary roof span & 20m high freestanding side scaffolds.
