Accounting/Processes for Capital Projects (Construction)

Hi all, hope everyone is keeping well ..

I have been told this morning that I might be dragged in to the PROJECTS department .. honestly speaking, I have no clue whatsoever about project accounting or what are the processes involved or the terms used like RETENTIONS...etc.

Is there anyone on this forum who is/have working/worked in the project department and can give a crash course on the processess involved and the accounting involved. In depth details not required, just something for me to begin with

thanks in advance and appreciate all your help

best regards
