I’ve worked on several bid projects with the Sweett Group. I usually begin by creating a brand for the joint venture, then design bid documents, folders, CDs, diagrams etc.

Alba, Hub and the Miller Wellspring Partnership are all connected to differing degrees, so I’ve kept a continuity through the brands.
Colours are generally led by the partnering organisations’ brands.

More detailed illustrative branding used for the Alba bids; example of the maps created for hub bids.
