In terms of the management of this, I would invite my colleagues to join. In terms of the specifics of that aspect, the contractor is required to pre-qualify firms, both consultants and contractor/suppliers, in the databank. They then go on a rotational basis and select those firms and ask them for a price. Then the lowest price from those five firms is used to conduct the work.
