VIII. Format of Proposal

The proposal shall consist of 10 Work Packages (WP).

WP 1 : Bidder's Qualification Document

WP 2 : Overview and Technical Proposal

WP 3 : Warranty Proposal

WP 4 : Maintenance Proposal

WP 5 : Training Proposal

WP 6 : Transport - Handling - Storage Proposal

WP 7 : Work Schedule and Installation Plan

WP 8 : Acceptance Test Plan Proposal

WP 9 : Documentation

WP 10 : Price Proposal

The bidder shall present 6 copies of the proposal. A4 or letter size paper shall be used. The bidder

is requested to strictly follow the following illustrated format (tabular form). This is very

important to compare and evaluate different bidders’ proposal. Consequently, disregard for this

rule may end up with disqualification. Also, well-prepared and well-organized proposal will be

highly appreciated and evaluated. The landscape orientation will be acceptable for tables. The

suggested contents in each WP are minimum requirements and works for reminiscences.

Ambiguous expression will act adversely to the bidder.

Note : The prices which are used in the proposal to calculate the final total and breakdown prices

shall be distinguished from the other prices (e.g. optionally suggested parts by the bidder

or KARI, . . . ) by marking a.p. (applied price) after the prices. In other words, the sum of

a.p. shall be the final total price proposed in the proposal.
