The Engineer shall have the authority to suspend the work wholly or in part for such period as deemed necessary, due to unsuitable weather, or to such other conditions as are considered unfavorable for the suitable prosecution of the work, or for such time as it may deem necessary due to the Contractor’s failure to carry out orders given or to perform any work provisions.

The Contractor shall immediately obey the Engineer’s suspension orders and shall not resume work until so ordered in writing by the Engineer.

If the Engineer orders a work suspension due to the Contractor’s failure to carry out provided orders or to perform any contract provision, the days on which the suspension order is in effect shall be considered contract working days if such days are working days within the meaning of the definition set forth in these specifications.

If work is suspended through no fault of the Agency, all expenses and losses incurred by the Contractor during such suspension shall be borne by the Contractor. If the Contractor fails to properly provide for public safety, traffic, and protection of the work during suspension periods, the Agency may elect to do so, and deduct the cost thereof from monies due the Contractor.
