(4) Construction Period: From the day after contract signing to January 15, Reiwa 9. (5) This construction is a target construction for which document submission and bidding are conducted through the electronic procurement system. However, if it is difficult to use the electronic procurement system, paper bidding may be used with the consent of the contracting party. 1) The window and reception hours for this application are as follows: - Reception Window: Same as 6. - Reception Hours: 9:00 AM to 5:00 PM (excluding 12:00 PM to 1:00 PM).

However, in exceptional cases where the bidder has unavoidable circumstances and the overall bidding procedure is not affected, as recognized by the contracting party, it may be permitted. (6) This construction is subject to the "Weekly Two-Day Holiday System Construction (Site Closure Type) [Designated by Contracting Party or Bidder's Choice]" which ensures two days off per week by closing the site. At the time of bidding, the construction cost will be calculated by compensating labor costs, etc., based on the premise that the ratio of site closure days in all months within the site construction period will be 4 weeks and 8 days (28.5% (8 days/28 days)) or more, from the initial estimated price. The concept of two days off per week is as follows: (a) Two days off per week on a monthly basis means that it is recognized that 4 weeks and 8 days or more of site closure have been achieved in all months within the site construction period. Two days off per week for the entire period means that 4 weeks and 8 days or more of site closure have been achieved during the site construction period. (b) The site construction period is the period from the start of construction to the completion of construction, but it excludes 6 days for year-end and New Year holidays, 3 days for summer holidays, periods for factory production only, periods of temporary suspension of the entire construction, and periods where site work is unavoidable through no fault of the contractor. (c) 4 weeks and 8 days or more on a monthly basis means that the ratio of site closure days in all months within the site construction period reaches a level of 28.5% (8 days/28 days) or more. However, in months where the ratio of Saturdays and Sundays in the calendar is less than 28.5%, it means that site closure has been achieved for a number of days equal to or greater than the total number of Saturdays and Sundays in that month. Four weeks and eight days or more for the entire period means that the ratio of site closure days during the site construction period reaches a level of 28.5% (8 days/28 days) or more. Unexpected site closure days due to rain, snow, bad weather, etc., shall also be included in the site closure days. (d) Site closure days refer to days when the site or site office is closed for the entire day, excluding days when necessary work for site management, such as patrol inspections and maintenance checks, is performed. (e) If two days off per week on a monthly basis cannot be achieved, but two days off per week for the entire period can be achieved, the compensation coefficient will be changed. If two days off per week for the entire period cannot be achieved, the compensation coefficient will be deducted, and the compensated labor costs, etc., will be reduced by the contract amount change. 4.
