The new exhibition centre and associated four-star Pullman hotel development were originally set to open in the summer, but the official month has now been given as September.
When it does open, the centre will more than double the existing 7,125sqm capacity at ACC Liverpool to 15,225sqm and will link to the existing arena and convention centre via a pedestrian link bridge, making the building the only purpose-built arena, convention and exhibition centre in Europe.
Bob Prattey, chief executive of ACC Liverpool, said: "We are now less than a year from opening and are pleased with how the project, which is one time and on budget, is gathering pace. Our teams are working hard to ensure that we have a busy calendar of exhibitions, conferences and entertainment events for visitors."
Exhibition Centre Liverpool is expected to host about 50 events and attract more than 250,000 visitors in its first year of operation. Confirmed events so far include the Federation of Petroleum Suppliers FPS Expo, MCM Expo group and the RenewableUK conference.
Mayor of Liverpool Joe Anderson said: "The new exhibition centre will help secure Liverpool’s place as one of the top visitor destinations in the UK. This great new facility will become the jewel in Liverpool’s expo crown and will further enhance the city’s global events and conference reputation."
