The site: The City of London Hotel.
City of London Hotel
One of several major internal drainage descales to get sites operational after lockdown
The problem: The Covid-19 lockdown in Spring 2020 meant that many office and hotel drainage and plumbing systems were shut down completely. On many sites Metro Mechanical work on, this caused pipework to dry out and become filled with heavy scale, which created serious blockages. We were called to a major high-rise hotel in the City of London after routine legionella testing had led to flooding in multiple rooms.
Our 24/7 helpdesk assigned reactive engineers to clear the flood and remove the blockages
All our reactive crews carry camera equipment, so they were able to assess the state of the internal stacks at once
A full site clean using powerful Picote equipment was recommended to address the major scale issues
As this was a ‘live’ site (i.e. the hotel was in use), we had to work carefully with the FMs to phase our work
We painstakingly carried out our work room-by-room, floor-by-floor over a number of weeks
Our drainage engineers used Picote MaxiMiller coring equipment to descale the system, and checked results with camera surveys
Meanwhile, our plumbers replaced faulty pipework and added support brackets to prevent overloading joints on suspended lines
Waste was removed using one of our 7.5 tonne Cityflex tankers
We didn’t just clear the drains on this site: we comprehensively upgraded the system
We eliminated a major environmental and health & safety risk to the site
We allowed the hotel to trade fully after the initial Covid-19 lockdown
