This technical report, referred to herein as the "Guide", is intended to assist in the preparation of Tendering Documents and tendering proposals and in the evaluation of tenders for hydraulic machines.
The object of this technical report is to provide a general guide for preparation of Tendering Documents (TD) for the supply, installation and testing of hydraulic turbines, storage pumps, and pump-turbines herein referred to as hydraulic machines as defined in 2.2 of this publication. This technical report considers the case where both equipment supply and site installation are carried out by the same Contractor. In those cases where site installation is not included in the scope of work, the Tendering Documents should include supplementary provisions for site supervisory services to be provided by the equipment supply Contractor and for day-to-day interface with the site installation Contractor.
Hydraulic machines for small units with power less than 5 MW and with runner/impeller diameters less than 3 m are covered in IEC 61116. These limitations are not intended to be absolute and will depend on the type of machine and on other project characteristics.
