Note: The successful bidder in the box above should be read as the 1st ranked successful bidder candidate.
2. In ② above, the number obtained by adding 2 to the remainder (within the blue box) will be the 2nd ranked successful bidder candidate, adding 3 will be the 3rd ranked successful bidder candidate, and so on, determining the order for all lottery participants.
If the sum of the remainder and the added value exceeds the number of participating companies, it will be the number obtained by subtracting the number of participating companies from the sum.
The lottery results will be sent along with the successful bidder determination notice.
3. The 1st ranked successful bidder candidate will be contacted by phone, etc., requested to submit documents, and their competitive participation qualifications will be examined.

This process will be repeated from 3 and 4 until a candidate is confirmed to meet the competitive participation qualification requirements.
Electronic Lottery: The Kanagawa Electronic Bidding Joint System can conduct an electronic lottery based on the lottery number entered in the bid when a lottery is required after the bids are opened.
The electronic lottery mechanism is as follows.
① Bidders participating in the lottery will be sorted in ascending order by lottery number and assigned a "rank number".
(If lottery numbers are the same, the order of bid submission will be used.)② The number obtained by dividing the sum of lottery numbers x by the number of lottery participants z, and adding 1 to the remainder, will be the "winning number".
Calculation formula: (x + y) / z = m ... n Winning number = n + 1 (Example) If x = 16, y = 250, z = 3, then (16 + 250) / 3 = 88 with a remainder of 2. Winning number = 2 + 1 = 3. ③ The bidder whose "rank number" matches the "winning number" will be the "winner = successful bidder".
*Even if the same lottery number is entered, only one successful bidder will be selected.
