CTRs Gas Plant [Example]
This is an Open Document that represents a system used by a particular EPC Contractor for development of CTRs. The system is a legacy from successive previous projects and it uses word documents to hold CTRs expressed as tables populated with the CTR (Cost Time Resource) information.
They included a template set of CTRs using this system, in a tender for FEED services. 
The branching structure presents three main levels (1) Collections of documents, (2) individual documents and (3) individual CTRs. 
The main purpose of this Open Document is to allow the project team an easy reference to the location of individual CTRs and a means to provide comments directly and efficiently to the CTR development manager.  
A secondary purpose is to ease the migration of CTR information into a CTR database that develops CTRs to the WBS (Work Breakdown Structure).
