During the Great War the field companies had a problem of running workshops and maintaining stores in the forward area… In 1919 the R.E. formed the Rawlinson Committee to look at the problems of engineer organisation and control. One of their hundred recommendations was: "That a headquarters of specially skilled men should be included in the establishment of divisional engineers." Thus the the Field Park Company was born to handle the workshops and stores that the Field Company previously handled.
Google "engineer field park company" and check out a few of the resulting links. British-model (Commonwealth) armies in WW2 had field park companies at the divisional level away from the immediate combat area to run specialised workshops and maintain divisional engineering stores.
