2. Coordinate with MISS DIG (811) and other Agencies having jurisdiction over property or structures in and around the construction area and locate all utilities potentially affected by the Work.

3. If at any time, Contractor’s resources appear to the Engineer to be inefficient, inappropriate, or insufficient to achieve the required quality or rate of progress of the

Work, the Engineer may ask the Contractor to increase the efficiency, change the character, or increase the number of personnel and equipment to meet the schedule of the

Contract. Failure of the Engineer to give such direction shall in no way relieve the

Contractor of its obligations to secure the required quality or rate of progress of Work.

B. Hours of Work:

1. Contractor may normally prosecute the Work during the daylight hours, and in no case earlier than 7 AM or later than 7 PM of any weekday, providing that the operations are conducted as to not create a public nuisance or disturb the peace. However, should the

Contractor be stopped, by order of a public authority, from working at times that are contrary to or in violation of any law, ordinance, permit, or license, the Contractor shall not be entitled to an extension of time due to such stoppages.

01 14 00 - 2

2. At the beginning of Work, notify the Engineer in writing, of the days and hours that will constitute a normal work week. Whenever the Contractor intends to depart from the specified work week, the Contractor must request approval in writing so that the Engineer may review the request for approval and make the necessary arrangements to have required inspectors assigned to the Work. The request shall be made at least two (2) calendar days prior to the requested deviation from the specified work week. If an emergency arises that would require work to be performed outside of the normal working hours of the specified work week to save or protect life or property, the requirements of the request for approval would be waived.

Request, in writing from the Engineer, approval for each shutdown a minimum of 14 calendar days prior to the proposed shutdown date. No shutdown shall be initiated until the inventory of materials and labor is verified by the Engineer on site prior to the proposed start date.

2. The Work required herein and any other Work required by the Engineer which may interrupt the normal operations shall be accomplished at such times that will be convenient to the Owner whether during the nighttime hours or during weekend hours.

The Contractor shall include in its bid price all overtime and/or premium time required for performing any work associated with these shutdowns.

3. Have on hand and located in close proximity to the Work area, all tools, equipment, spare parts and materials, both temporary and permanent, necessary to complete each Work category without interruptions.

Work necessary to immediately re-establish satisfactory operation. Notify the Engineer, in writing, immediately of any unscheduled shutdown. Permit Owner’s personnel to work with Contractor’s personnel, as deemed necessary by the Owner, to maintain the facilities in continuous satisfactory operation. Unscheduled shutdowns or interruptions of continued safe and satisfactory operation of the facilities that result in fines levied by regulatory agencies shall be the responsibility of Contractor if it is demonstrated that

Contractor was negligent in the Work or did not exercise proper precautions in the conduct of the Work.

01 14 00 - 3

5. Shutdowns of Electrical and Control Systems: Contractor and the Owner shall each lock out and tag circuit breakers and switches operated by the Owner and shall check cables and wires to be sure that they are de-energized to ground potential before Work begins.
