Gracechurch Street...

The Gracechurch Street Project is located near the Monument in Central London. The Roof of the building is clearly visible from the top of the famous memorial.

The Package:

NDM Were contracted to provide both the Substrate, Louvers, Mansafe System and Cladding to the Plant Room located on the roof.

The Design:

NDM were able to value engineer the original architects design to be more cost effective and achieve a higher specification.

NDM were handed a shell of structural steel to which we fixed our substrate which was later clad in zinc. NDM were also able to simplify the louvre design to speed up installation time.

Materials Used:

Roof:

NDM's structurally engineered design for the roof meant that additional Metsec Purlins were required to support the composite Panel Substrate. These were fixed to the structural steels using thick galvanised steel brackets.

Each joint in the composite panel first had a mastic seal applied to increase the weather tightness of the roof prior to the zinc being laid (allowing trades inside the building to start sooner.) All joints were then sealed with foil tape. Any exposed cut edges of composite panel were sealed using a galvanised steel angle manufactured by NDM.

A breathable Klober membrane was then secured to the composite panel and the Pre-Weathered Graphite Grey Pro Zinc was laid on top secured with stainless steel patent clips and self tapping screws.

Elevations:

The substrate consists of Metsec Purlins fixed into the Structural Steel and Kingspan Cold Store Composite Panels secured to both the Structural steel and Metsec Supports.

The build up then followed the same sequence as mentioned above.

Several Louvres were installed as part of our package both to the flat roof and vertical elevations.
