Penneys Store, Mary St. Dublin. 



Sep 2014


Jade industrial were engaged by APM to design and build a number of structures to facilitate repair and maintenance to the historic Penney’s building in Mary Street Dublin. This project essentially had two key components, the Mary Street Façade access scaffold and the access scaffold to the historic roof dome. During structural investigations on site, large sub street level basements were discovered which severely limited the load bearing capacity of the street scaffold. Working in tandem with the site structural engineer, Jade designed a structure utilising steel scaffold beams to spread the imposed scaffold loads and to ensure placement of scaffold legs in line with the load bearing structures along the basement area. The main element of the works was to provide a complete wrap around safety and access scaffold around the main roof dome which dates back to the early 1900’s. The roof in this location had extremely limited load bearing capacity so Jade had to design and engineer a structure, which could provide access around the dome, without bearing on the roof itself. Structural steel ‘I’ Beams were lifted via crane and installed to span from structural walls to the front and rear of the dome and to both sides. Jade then installed Haki 750mm scaffold beams to span between the structural steel and to provide a base from which the access scaffold could be built. Given that the dome looks down grandly upon the busy Mary Street Shopping street, this presented many logistical and safety challenges as the public had to be protected from the works at all times.  With this in mind, the scaffold structure had to be built at night time under task lighting, to minimise risk to the public. This project is a great example of the end to end service provided by Jade from design engineering to project Management and delivery of a highly technical access scaffold.
