SCHEDULE E4 - CONTRACTOR’S SUBMITTALS - DRAWING AND DESIGN DATA
The Contractor shall submit all drawings, samples and models for approval in sufficient time to permit modifications to be made if such are deemed necessary, and the drawings and samples and models to be re-submitted without delaying the initial deliveries or completion of the Contract Works. The time allowed for the Employer to review and comment on drawings, samples and models shall be agreed.
If the Contractor requires early review of any drawing in order to avoid delay in the completion of the Contract Works, he shall advise the Engineer to such effect when submitting the drawing.
The drawing format and the indexing system, will be agreed at the first Contract meeting between the Contractor and the Engineer. The number of copies of each drawing or of any subsequent revision to be submitted to the Engineer for review shall be advised to the Contractor by the Engineer.
Drawings, samples and models submitted by the Contractor and approved by the Engineer shall not be departed from without the instruction in writing of the Engineer.

GUARANTEED TRANSFORMER LOSSES AND PENALTIES
The Tenderer shall complete the following guarantees based on highest declared rated power at Site conditions.
132/33/11.5kV 63/50/25 MVA three winding transformer as specified. Item Description
Unit
1 No load losses (NNL) at rated voltage ratio at IEC rating
kW
2 Load losses (LL) at 75°C and rated ONAF power and principal tapping: HV/LV winding at IEC rating
kW
3 Total losses (TL=NNL+LL) kW
1. Loss Evaluation
For the purposes of tender evaluation the 132/33/11.5kV transformer losses will be capitalized, in the following manner: Transformers No-load loss (NLL) 3052 US$/kW at rated voltage Load loss (LL) 730 US$/kW at rated MVA and voltage 2. Penalties A maximum variation of +10% of the total declared losses (TL) is permitted. Any transformer (or reactor) with losses more than +10% of the Total Loss (TL) declared will be rejected, unless otherwise agreed by the Engineer. For transformers (or reactors) with total losses within +5% of the declared losses no variation of the contract price will be made. For transformers (or reactors) where the total losses are between +5% to +10% of the total declared losses the contract price will be reduced by the total capitalised cost of losses in excess of the capitalised cost of the declared guaranteed losses. For any transformer (or reactor) with total losses less than 100% of the guaranteed losses, no variation of the Contract price will be made.
