The DHL building is situated on the ‘Magna Park Lutterworth’, the largest logistical park in the UK. As they themselves say, this is the largest and most successful distribution centre in Europe. In this warehouse, DH supplies the logistical operations for BP, inventorying all of the shops/gas stations in the UK. The total surface to be cleaned was 7,500 m² at a height of over 15 meters. A good collaboration was important, considering that this logistical centre is open 24 hours a day, all work activities had to go on without interruption. Together, we considered the best plan of action and planning so that both parties could continue to carry on their work. Win, win!
