The job has been split into two parts with separate contracts for the temporary 20,000-seat stands and specialist work installing and maintaining competition and training pitches.

Work on the temporary stands is being procured by The London Organising Committee of the Olympic and Paralympic Games (LOCOG) who hope to award the contract by late summer.

The main competition arena will have a 15,000 seat capacity with the second pitch overlooked by a 5,000 capacity stand.

After the Games the Hockey Centre will move to the north of the Olympic Park, joining a group of facilities in the area known as Eton Manor. It will have 5,000 permanent seats with the ability to increase to over 10,000 for major events.

The pitch construction contract is being overseen by the Olympic Delivery Authority and the job involves installing and maintaining competition standard pitches for at least four years.

An ODA spokesman said: “We are currently procuring the training and competition Hockey pitches for Games time and legacy and LOCOG is leading on designing, procuring and delivering the temporary Hockey Arena.”
