4.2 Site location

The specifkation should dEScribe the ge.ngraphical

location of the site, which may include surveying

points, the previous use of the site and any local

features such as the impact of industrial or military

activities and planning restrictions

Where applicable, the spec(fkation should indicate

site datum on spec(fkation drawings and specify

site and drawing orientation and define co-ordinate

axes (x, y, z) and numbering order to ensure

consistency between suppliers of connected equipment

Where appropriate, the spec(fkation should define

the permitted ground loading, dimensiana1 and time

restrictions on access routes up to but rwt including

public roads or railways

The spec(fkation should identify, where appropriate,

the environment of the site in which the equipment

will operate The following factors may rwrmally be

- climatic e.g atmospheric pressure, annual

variation of air and cooling water temperature,

relative humidity, rainfall, icing, snow, l1n11d

velocity (normal and maximum), lightning;

- geological e.g seismic conditions and

characteristics of subsoil (e.g caverns, gliding

stratifications, load bearing capability of subsoils);

- geographic e.g elevation, inJluence of local

topography and structures;

- hydrological e.g flooding and tides, range of

water temperature, water quality analysis (chemical,

corrosive, biological, suspended solids)

4.3 Equipment task

The specifkation should describe in generol terms

the junction, task or role of the equipment to be

purchased, e.g whether it is part of a new JXYWer

generating plant, a 1rwdification to an existing JXYWer

generating plant or replacement equipment

Where appropriate, the specification should define

the function and the known limitations, if any, in the

equipment connected to that which is being supplied

so that the equipment may avoid imposing adverse

conditions or the supplier may suggest modifications

to connected equipment which would ensure

satisfactary operation

4.4 Equipment to be purchased

The specification may define the equipment type or

arrangement to be purchased

For example, the purchaser may specify the:

- machine type, e.g Francis, Pelton, etc.;

- machine characteristics;

- preferred arrangement, e.g vertical or horizontal

shaft;

- preferred bearing arrangement;

- preferred speed;

- preferred reference level of the machine

The specification should give a description of the hydraulic scheme (dams, reselVoirs, conduits, etc.) and

a description of the hydraulic circuit (intake, gallery, surge tank, penstock, gates and valves and t.ailrace)

The spec(fkation may also define preferences for equipment types (or give information) regarding compatibility 11Jith existing equipment, if required

The spec(fkation slundd dlifine the intended methods

or local practice for maintenance, inspection and operation

The spec(fkatwn should define requ'irements with regard to the general appearance of the equipment (e.g dimensions, shape or colour) to meet local

planning requirements or specific criteria, where such

rPJ}Uirements exi.<;t

legislation which may place restrictions in this area

4.5 Control and instrumentation The spec(fkation should define the general requirements for the control and instrumentation

required, integration with otJter control systems, localized control loops, commonality and redundancy

instrumentation systems jor pOUJer stations, including advice on

4.6 Electrical supplies and other services The spec(fkation should define the electrical supplies available for the operation of the equipment, their voltages and frequencies, 11Jith their range of variation, phases availahle and, where appropriate, the acceptable 'IXllues of maximum load (Ie ~ and short circuit level at each voltage level and the

harm.onic content Requirements for terminals and terminal boxes should be stated; these should be to a recognized European or international standard

The specification should define the type and capacity of other services for the operation of the equipment, such as compressed air

4.7 Other inter:faces The specification should define the interfaces with existing ancillary 01' new ancillary equipment to be

supplied under separate contracts which interact directly with the equipment For example, civil

works, cranage or temporary systems

4.S Project programme The spec(fkation should describe the overall programme and timescale in which the project is to

be carried out This may include the principal dates associated with tendering, placement of orders, access

to site, start and completion of installation, pre-start tests, commissioning, take-over and final acceptance

4.9 Equipment identification systems The specification may specify the equipment identification system for use during the operating life

of the plant If applicable to the project, a recognized European or international system should be used
