4.3 Curryingout Repair &MaintenanceWorksDepositsIt is not worthwhile to impose non-refundable deposits from tenderers asthis practice may deter good contractors from submitting a bid for the job.(c)Selection Methods(i)Common selection methodsThere are several methods to procure a works contract. The more commonlyadopted ones are open tender, selective tender and negotiated tender.Open tenderUsually an advertisement is put up to invite publicly for an expression ofinterest to submit a tender. The difficulties to predict the number of respondentsadd uncertainty to the work flow. If there are many interested tenderers,an enormous waste of vetting efforts by the Project Consultant and resourcesin preparation of tender documents and to check the quality of the tenderersis expected.Selective tenderInvitations are sent to a selected list of tenderers formulated by pre-qualification,recommendations through building professionals and other building owners,etc. It is advisable to include in the list only those who are interested andthose OC is prepared to accept. Unnecessarily long list of tenderers willindirectly affect the quality of the submitted tender. OC is therefore, wherecompetition is required, recommended to adopt selective rather than opentendering with the maximum number of tenderers limited to five or six.NegotiationIf only minor repair works are involved and the owners know some goodcontractors, selection of the contractor by negotiation may be a relativelysimple solution. However, this method is usually not recommended for largescalemaintenance works of multi-ownership buildings because it is notconsidered as a fair process and may easily attract complaint on bribery.SELECTING THE APPROPRIATE SOLUTIONS
