Tall order

Principle Cleaning Services has won a contract to clean No.30 St Mary Axe,a London address over three times the height of Niagara Falls. Nicknamed 'The Gherkin' it not only provides flexible space and spectacular views but it is taking the lead in setting new standards socially, spatially and environmentally.

Responsible for daily cleaning to the washrooms, lifts, lobbies, reception areas and common parts, the company will be providing cleaning operatives, housekeepers and a full time site manager. Other periodic tasks and floor maintenance will also be carried out, which is a significant task as each stairwell has 1,037 stairs - three times more than the London Monument.
