Harpenden



Contractor : Morgan Sindall
Location : Harpenden, London

We designed, fabricated and installed a complete ‘Access for All’ station in Harpenden. The structure consisted of 19 individual component sections connected together to form one complete structure. Each individual component was fully fabricated, clad, glazed, N1 spec painted and had non-slip flooring applied in our workshops before arriving onsite.

Individual Component Structures:
3 x Lift Shafts - 3 x Roof Frames - 4 x Staircases - 3 x Link Bridges - 2 x Over-Bridges - 3 x Glazed Canopies - 1 x Waiting Shelter

Design
Our detailed fabrication drawings allowed for 90% of the fabrication process to be completed in our workshops before the structure arrived on-site, thus drastically reducing the ‘track possession’ time required for installation. Furthermore, the design of each component part incorporated simple bolted connections - to allow quick and precise installation onsite and eliminating the requirement for any on-site welding.

‘Trial Installation’
Our fabrication facilities include a dedicated ‘trial installation’ bay which enables us to carryout mock erections of a structure. This allows us to deal with any unexpected issues that may have arisen in the confines of our own premises before the structure arrives onsite – ensuring a trouble free installation and reducing the ‘track possession’ time required for installation.

Installation
The complete structure was fully installed in only 7 night-time ‘track possessions’ each lasting 8 hours. A 250 tonne crane was used to lift each component section into position with slinging and lifting co-ordination provided by our team. The station remained open between possessions without any delay or disruption to its operations.
