King's Cross Underground Station (LUL)

Theory

The aim of the Station Refurbishment at King’s Cross-St Pancras is to provide maximum safety and reduced congestion to meet an anticipated 100% increase in passenger traffic over the next 20 years, making it the busiest London Underground Station

Practice

The project comprised two elements, doubling the size of the existing Tube Ticket Hall and then constructing a new Western Ticket Hall. The latter was a 3-storey building with plant rooms under the forecourt of St Pancras Station and the Bailey Rail installation covered all of these areas.

Original workscope included:

• Power
• Lighting
• Ventilation and Air Conditioning
• BMS
• Sanitaryware and Soil + Waste

The scope increased significantly to include additional:

• Fire Alarm and Public Address Containment
• Sprinkler Systems
• Additional Communications containment (Clocks, Data, Telephones, Help Points etc
• Sanitaryware
• Effluent Pumping and Drainage
• Fire-rated and Pressurised Ductwork Systems
• Deepline Containment (for specialised services on all platforms and concourses)

Bailey Rail also undertook all services diversions and enabling works. Midway through the project Bailey Rail was instructed to survey routes for the deepline platform areas containment.

Timing was an issue throughout the project with no access to the work until train operations ceased. Only then could scaffolding be erected, materials and equipment brought in and installations commence. At times, the installation window was as little as 90 minutes per shift.

"The Western Ticket Hall will be a fitting gateway to London for passengers from the UK and abroad"
