0.    INTRODUCTION

       This specification provides the definition of the Response of
       pending works message (CONRPW) to be used in Electronic Data
       Interchange (EDI) between trading partners involved in
       administration, commerce and transport.

1.    SCOPE

       The construction industry uses this message during its design,
       building and maintenance stages. It communicates with
       organisations about existing and planned services in the
       vicinity of the works.

1.1   Functional Definition

       This message is a reply to a CONAPW message and enables service
       providers to respond to a contractor giving details of any
       services and networks in the location where construction work
       is to be undertaken.

1.2   Field of Application

       The parties involved in such transfers belong to various
       industry sectors :
       
       - the construction industry : contractors are the recipients of
       the message.
       
       - gas, electricity, ... and more generally network distributors
       who are among the senders of such messages, and who will
       process them to advise contractors of the presence of existing
       networks.
       
       - public authorities, which may be
       	- clients or designers of projects
       	- in charge of specific responsabilities eventually affected
       by the projects.
       
       - in some cases, this type of response on a formal advice may
       have a legal status, the consequence of it may be the liability
       of the sender or receiver. Some insurance companies also may be
       concerned by this message.

1.3   Principles

       This is only one of a group of messages being designed for this
       flow among construction industry. Many aspects have to be
       considered, they are described in the following paragraphs.
       
       This message is the response to a prior request of information,
       which has eventually been sent through another appropriate EDI
       message.
       
       The type of the information to convey in the "flow" CONRPW is
       not only alphanumeric, but some geographical and graphical
       information may be conveyed in conjunction with the response
       itself, in order that the recipient gets all the relevant
       elements on the existing networks. There is another appropriate
       EDI message being designed to convey information on plans and
       drawing organization, and it has been decided not to put this
       information in the message CONRPW itself, but to give an
       opportunity to link CONRPW with the drawing organization
       message.
