                          in the world, so that the recipients’ comments thereon can be returned with-
                          out delay. Thus specialist engineering guidance centred in one part of an
                          organization can service the needs of others in distant locations. Computer
                          aided drafting (CAD) has also become the norm for production of all formal
                          drawings and to some extent for engineer’s sketches.
                            A further development has been the integration of the design process with
                          the requirements for construction. An Intranet can be set up to link people
                          together within their own organization. Drawings and design information,
                          specifications and bills of quantities for a construction project can be stored
                          centrally and accessed by all authorized members of a design team, with only
                          certain members authorized to alter the details. This means that drawings and
                          data being used are always current, there are no delays caused by awaiting
                          information, and the process of making changes can be controlled and audited.
                          A design change can, for instance, lead to an immediate change in the contract
                          drawings and the relevant specifications and bills of quantities.
                            A natural development has been to extend the availability of data to other
                          parties concerned with a project – such as the employer, the principal con-
                          tractor, and perhaps to certain specialist suppliers or advisers involved – by
                          setting up an Extranet using the Internet. Such arrangements can be variously
                          termed ‘project collaboration’ or ‘project portal’ systems. But greater care then
                          has to be exercised in the selection of information made available on-line, in
                          restricting access to it by only certain authorized parties, and in providing
                          adequate security protection. This type of Extranet collaboration is also useful
                          between firms when Partnering, Alliancing, or Joint Venture (see Sections 1.9
                          and 1.15) arrangements are adopted. An Extranet system is usually procured
                          from a specialist website service provider, and has at least two main divisions –
                          (i) a data division containing the basic information deemed necessary; and
                          (ii) a division for recording inter-party communications. Computer software
                          must be compatible and the set-up cost can be high, so that Extranets are
                          mostly used for large projects.
                            Some difficulties can arise with computerized project collaboration. There is
                          doubt whether a contract instruction from one party to another via such a sys-
                          tem is legally valid in UK where contracts normally require instructions to be
                          issued ‘in writing’. There are also potential problems in preserving copyright
                          of designs. Whereas ‘hard copy’ contract drawings provided to a contractor
                          must usually be returned to the design engineer on completion of a contract,
                          there is no equivalent precaution that can be taken when drawings can be
                          archived on disks.
                            The fact that the various parties inter-connected can communicate freely
                          with each other can also tend to blur responsibilities. Care must be taken to
                          ensure that communications conform to the contractual position each party
                          holds, so that misunderstandings do not arise. Also the ease with which key
                          specialist advisers or project managers can be contacted can result in them
                          being overloaded with requests to assent to some proposed action. The danger
                          this creates is that, with limited time for the specialist or manager to consider all
                          the ancillary circumstances applying to the often complex problems arising in
