All expenses in moving to the new site and returning to the original site when repairs can again be made shall be borne by the Contractor.

1.11 RIVER STAGE AND WEATHER LIMITATIONS:

1.11.1 No work will be permitted under this contract at times when the river is at or above natural high bank, or when the local gage in the vicinity of the work indicates flood stage or higher, unless specifically authorized in writing by the Contracting Officer. When construction work is prevented during such times and because of such actions, the Contracting Officer will determine the extent of the delay to the work as a whole, and the time fixed for completion of the contract will be extended for the period of such delay.

1.11.2 Low River Stages

1.11.2.1 In the event low water river stages require the Contractor to lighten his barges to a draft of less than 5 feet or to suspend operations entirely, the Contracting Officer will determine the extent of the delay to the work as a whole, and the time fixed for completion of the contract will be extended for the periods of such delay.

1.12 ORDER OF WORK

1.12.1 Unless directed by the Contracting Officer, construction shall begin with the first item in each task order.

1.12.2 Work on each specific scour repair, shall begin at the upstream end or landward end of each structure and shall proceed downstream or riverward unless variation is authorized in writing by the Contracting Officer.

1.12.3 The Contractor will be allowed to work on more than one scour location at a time provided work on scour locations is not delayed by work on repairs listed in each task order

1.12.4 The Contractor shall not be allowed to stockpile stone on the bank near any repair site.

1.12.5 The Contractor shall not begin placement of stone fill below the water surface when the discharge is predicted to exceed 40,000 feet per second during the required construction period unless otherwise directed in writing by the Contracting Officer. In the event that river stages force cessation of the work at any site, and work is required and can be performed at another site within the contract reach, such work will be made available to the Contractor. All expenses in moving to the new site and returning to the original site when repairs can again be made shall be borne by the Contractor.

1.13 WORK ADJACENT TO AND AROUND GOVERNMENT STRUCTURES

SECTION 01 14 00 Page 6 of 6

1.13.1 The requirements of the erosion control and protection work, such as location, proximity and limits of stone to be placed in structure and bank protection, and in scour hole repairs, will be determined by information provided to the Contractor in each task order and in the field by the Contracting Officer.

1.13.2 Before work is to begin at any site, the Contractor shall inspect that site with the Contracting Officer. The Contractor shall ascertain the types, size and approximate quantities of materials and specific equipment necessary to perform the repairs and/or stone placement indicated at that site and shall have sufficient material, supplies, and equipment available for use at the said site in time to permit the work to begin and progress without delay.
