                          6.4 Requirements for fast completion                    Tendering    69
                          There is a widespread tendency for employers to want their civil engineering
                          works designed and built in the shortest possible time. This pressure for speed
                          often arises because of the time it nowadays may take for an employer to gain
                          powers to construct his works. He may need to get planning consents, satisfy
                          conservation and environmental interests, acquire land and wayleave rights,
                          accommodate objectors and go through the lengthy process of a public inquiry.
                          The funding of international projects may also take some years to arrange and
                          negotiate. Commercial organizations tend to delay a project, then want it com-
                          pleted as fast as possible when market conditions are right. None of this can be
                          avoided; but the pressure to undertake both design and construction in exces-
                          sive haste needs to be resisted.
                            Starting construction before designs are complete or before the employer
                          is sure what he wants, is a major cause of constructional problems, claims by
                          contractors and of costs grossly exceeding original estimates. Hurriedly pre-
                          pared documents, contract drawings incomplete before tendering, tender
                          periods too short and an employer who wants changes after construction has
                          started, can lead to a legion of unforeseen problems, forced changes of design,
                          multiple claims from a contractor and a job not completed any earlier than it
                          would have been had proper time been allowed to get everything right before
                          calling for tenders.
                            The three outstanding requirements for fast completion of construction are:
                          • designs fully complete before tenders are called for;
                          • adequate tendering time for tenderers to prepare their bids;
                          • an employer who makes no substantial changes to his requirements after
                             construction has started.
                          Given good designs based on adequate site investigations, drawings provid-
                          ing all the details a contractor needs, and no changes during construction, any
                          competent and well-organized contractor can give fast construction. He can
                          also give a good job. The quality of a job is all-important to a contractor’s rep-
                          utation. The cost of a job and how long it took may fade from an employer’s
                          memory; but, if the job is a poor one giving a series of after-troubles, it will be
                          a continuing source of dissatisfaction to the employer, which he will not forget.

                          Tender preparation and assessment times need to be adequate; they should
                          be programmed into a realistic timetable which gives sufficient time for the
