The partners are still awaiting official Department of Transport approval for the full scope of the integrated station project, which is expected to cost £2.6bn.
Despite this uncertainly, the delivery team is inviting bids for a £10m-£20m multiple supplier deal for around 20 cranes due to be installed over 3-5 years.
Tower crane suppliers will be expected to have extensive demonstrable experience of delivering similar complex packages on previous projects of a similar scale
During the peak construction period at Euston, around 3,000 people will be working on the construction of the station.
The department has now spent the past 15 months looking for cost-saving options and efficiency opportunities, including the potential for a smaller station, depending on the scope of the northern leg of HS2.
The Government public accounts committee recently criticised the department for transport for dithering over the project, warning things were getting close to the point where the programme would literally run out of time if a decision was not made soon.
A final decision on Euston station is expected from DfT in the Autumn.
