Works at Salisbury Station included the refurbishment of a series of 19thC canopies in various states of disrepair.

Flaws included rotten timberwork, flaking paintwork, blocked drains and a mismatched collection of dagger-board valances and guttering which had been subject to crude ad-hoc alterations during previous decades.

Spence mobilised at the start of June 2013. As part of the planned works we submitted our temporary works design (scaffold) to allow us access to the underside of the canopy. One of the first tasks was to jet wash the diesel fumes and general dirt off of the underside of the timber canopy. The work was carried out by Jack Tighe Ltd and consisted of jet washing the timber and steel canopies working off mobile elevated working platforms (MEWPS) prior to any scaffold being erected.

Due to line blocks and working hour restrictions the time taken to erect the scaffold was too long. In the inaccessible areas scaffold was used with the other areas accessed via a combination of mobile scaffold towers and MEWPS.

Decorating works – Sub Contractor – Jack Tighe

All the timber and steelwork was prepared and painted in accordance with NwR standards. The majority of the work was carried out between 2000 – 0500 hours including a 3 hour window when track side painting works could be completed.

Timber repair and glazing – Sub Contractor – SUMO

Following a timber survey and schedule carried out by Spence, SUMO was awarded the contract to replace defective timber including eaves beams, purlins and tongue and groove works. The timber repairs were challenging and required detailed planning.

The glazing is a combination of lead work steel glazing bars and fire retardant GRP Georgian wire glass. The underside of the glazing bars was designed to match up with the paintwork and the top mullion designed to match existing as per planning conditions.

Drainage

Platform drainage was completed along with track drainage repairs.

Man safe system

To allow for future maintenance a man safe system was installed to all 5 platforms and was handed over to NwR at the end of the project.

Valance boards and Gutter

Spence submitted a revised design for the dagger boards which was approved as part of the planning condition with Wiltshire Council. The supplier of the valance boards and gutter was a local business in Salisbury and was procured directly by Spence.

The installation of the valance boards and gutter was carried out during line blocks (3 hour window) which required detailed planning for procurement, plant and materials.
