Background
Coventry railway station in the West Midlands, which was originally built in 1840, is on the Birmingham loop of the West Coast Main line with four trains an hour passing through on the way to London Euston. The current station was completed in 1962 and is now a grade II listed building.
A major project of essential works in and around the station was underway by Galliford Try and this included the refurbishment of trackside and platform roofs.
Challenge
The existing builtup roof waterproofing was in such poor condition that water was ponding and penetrating the building. Splits were evident in the perimeter details which had been caused by differential movement in the aluminium edge trim.
James M Green had to cope with roofs sited underneath power cables which could only be worked on at night with limited access and limited scaffold space. All personnel on the project had to undergo two days of Personal Trackside Safety Training to prepare them to work alongside 25,000 volts of electricity in limited lighting conditions.
Solution
Network Rail wouldn't allow stripping of the existing roof as it would take too long, and so the Profiles system was chosen so they could overlay the existing roofs easily in floodlit conditions.
James M Green applied the new Profiles warm roof system, which included Icopal Thermazone insulation to meet required u-value standards and was topped with FireSmart Profiles XL capsheet.
Parapet details were treated with Icopal’s Antrim GRP edge trims and the totally integrated roofing specification also included Icopal Roofguard Outlets, Telescopic Vent covers. The Profiles system is an engineered elastomeric bitumen waterproofing system supported by a 20 insured guarantee. Materials were supplied on a like-for-like basis to comply with the limitations imposed by the station's listed status.
Teams of eight roofers worked in 12 hour shifts, 7 days a week to complete the job, which was finished ahead of schedule at the beginning of August; completed in just one month.
