In this stage the suppliers are invited to further elucidate their proposals. It may include visits to the suppliers manufacturing plant (to check the potentials, quality design and manufacture capabilities etc.) and a verification in the suppliers support of the presented specification. In some cases visits are made to relevant installations earlier supplied by the potential contractor. Evaluation of the presented proposals This is the most crucial stage in the whole procurement process. The evaluation will comprise a large number of technical features (such as: design approach, component types, sizing of major elements, dimensions of components, etc.), commercial conditions (delivery time, payment periods, warranty, liabilities, currency etc.) and some secondary aspects (quality of communication, language, flexibility, appearance in the proposal stage, reputation, etc.). It is recommended to prepare a complete overview for the various assessment criteria and in many cases a consulting engineering company is invited to support in this stage in order to assure an objective assessment of the various proposals. Confirmation of available budgets After the evaluations it will be clear which consequences will result from the planned ordering of equipment (total value, payment terms, project team, travel expenses etc.). Then it must be checked whether the organisation who wants to install (acquire) the new equipment is really prepared to provide the funding, to guide the implementation and accommodate the commissioning. This is necessary before the final contracting can start. Finalising the contract After negotiating the definite technical specifications and all commercial conditions, a contract should be made in such a way that both parties feel satisfied with the final result. The intent of the contract must be clearly described and all the expected deliverables must be clear to both parties. For large procurements (> 0.5 mio Euro) it will be necessary to inform the works council. In many cases it is recommended to start informing the works council in a very early stage especially when new equipment will support automation or when new equipment will change work procedures, will require less people etc. The contract will describe how the supplier will conform with the pending CE-directives (“Machinerichtlijn”). A relevant flow diagram is given in appendix A. Design stage The supplier will deliver a complete set of design drawings including a listing of all sub-contractors for the major components. In this stage the supplier and the principal will cooperate very intensively. Manufacture, erection and commissioning During manufacture the principal will monitor the qu...
