The latest "Contract Journal" company profile (see Cyril Sweett on BIW in late March and Rok set on in-house capability in January) features consultancy business WSP. On the project collaboration tools question, Andy Scott, global IT director says:
"… Internally, we have IBM TeamWorkplace and Microsoft Sharepoint. Externally, we’re driven by what our clients want and this can be any of the major applications, such as Infochannel, Hummingbird or Buzzsaw."
I think InfoChannel refers to BIW Information Channel, while Hummingbird probably refers to the construction management tool developed for use on Bovis’s UK projects, not the EDMS tool developed by the Canadian software firm of the same name.
