will be provided by the Purchaser. All accessories and works required for connecting
these power cables will be the responsibility of the Supplier/Contractor. The Supplier/Contractor will not be responsible for the guarantee of the power cables but will
be responsible for the guarantee of all connections.
1.3.2 Old Power Station Substation
The Contractor shall be responsible for dismantling of the existing two main protection relays, which should be delivered at EAC stores, and the installation, setting up and commissioning of new distance and current differential relays to the existing 132kV protection relay panel in order for the circuit to work.
1.3.3 Yermasoyia Substation
The Contractor shall be responsible for dismantling of the existing two main protection relays,
which should be delivered at EAC stores, and the installation, setting up and commissioning
of new distance and current differential relays to the existing 132kV protection relay panel in
order for the circuit to work.
1.4 PLANT ERECTION, TESTING AND COMMISSIONING
The Tenderer shall include the provision of all labor, technicians, testing and supervisory
engineers to install, test and commission the plant supplied under the Contract to the
agreed program and shall include all costs associated with the activity including the cost
of providing all necessary test equipment.
The Tenderer shall fully consider the Regulations regarding the use of local labor for site works and clarify in his offer where expatriate staff will be used on site activities.
Directions and instructions given by the Engineer's Representative or the Purchaser to the supervisors shall be interpreted as having been given to the Contractor.
The supervisors shall be well qualified by long training and experience in the installation and
operation of equipment of the type covered by the Specification. They shall liaise with the
Engineer and the Purchaser's staff in respect of the installation, testing and placing into
operational service of the substation equipment supplied under other contracts leading to commissioning of the complete substation or extension and for this purpose the English language shall be used.
1.5 BUILDINGS
Unless otherwise specified all substation buildings, foundations, walls, roof coverings,
concrete floor fittings, ducts and pipework embedded in the foundations, trenches with floor plates for cables, etc., will be provided under other contracts. Tenderers should take into consideration the following:
• dimensions specified as per drawings
• applied maximum load (including impulse load) on the floor of the GIS switchgear room
should not exceed 20 kN/m2
• the available crane in the GIS room can carry a maximum load of 5.000 kg.
The magnitude of the loadings from plant or equipment onto foundations must be stated by
the Tenderer. The loadings shall be confirmed by the dates given in the appropriate
schedule.
The Tender Drawings show the preferred layouts of all plant, equipment and buildings.
Dimensions in these Drawings have been based on typical sizes of plant and equipment.
The Contractor should ascertain for himself during the tender stage that the plant he
