U. UTILITIES

A. The County has endeavored to locate and show on the plans the approximate locations of all private and public utilities and facilities to be encountered during construction. However, it is possible that, during the work, unknown substructures requiring relocation or protection may be encountered. Such unknown substructures will generally fall into two classes:

Class I - Those requiring relocation or protection at the expense of the owner; and

Class II - Those requiring relocation or protection at the expense of the County.

B. For Class I utilities, the Contractor shall provide time and working space for protection or relocation activities and may be entitled to an extension of time for completion and/or extra compensation under the provisions of Subsection 5-5, "Delays."

http://www.ocwatersheds.com/documents/bmp/municipalactivities

C. For Class II utilities, the County will make arrangements for the protection or relocation by the

Owner or by the Contractor or by others. In the event either the protection or the relocation is to be accomplished by the Contractor, the procedures of Section 3, "Changes in Work," of the

Standard Specifications shall be used. In the event protection or relocation is accomplished by the owner or by others, the Contractor shall provide time and working space and may be entitled to an extension of time for completion and/or extra compensation under the provisions of said

Section 5-5, "Delays."

Contractor exercising reasonable care, the Contractor shall at once make necessary emergency preservations at no cost to the Contractor. Permanent preservations, if necessary, and/or relocation will be arranged by the County at no cost to the Contractor.

E. Where facilities are shown on the plans, "To Be Relocated by Others," the County will issue the owner a "Notice to Relocate" or, by County agreement with owner, require owner to relocate. In the event difficulties delay relocation, which in the judgment of the Inspector or County

Representative cannot reasonably be foreseen, and require a delay in Contractor's completion date after all reasonable remedies for keeping Contract on schedule have been exhausted by

Contractor including, but not limited to flow-charts and critical path scheduling, work simplification, and alternative construction methods, Inspector or County Representative may allow extra compensation and extra time to the Contractor.

F. The Contractor shall protect facilities shown on the plans, "To Be Relocated by Others," in both original and relocated positions and any damage to such facilities shall be immediately fixed to the owner's satisfaction at no cost to the County.

G. The Contractor's attention is directed to the utility notification service provided by Underground

Service Alert (USA). USA member utilities will provide the Contractor with the locations of their substructures in the construction area when the Contractor gives at least two working days’ notice to the Underground Service Alert by calling 1- 800-422-4133. The Contractor shall call USA prior to any work over substructures to allow owners to locate and/or obtain accurate "ties" on their manholes, valve covers, meter boxes, etc.

H. Full compensation for conforming to the requirements of “Utilities” shall be considered as included in the various items of work involved and no additional compensation will be allowed.

V. VERIFICATION OF UTILITY LOCATION AND DEPTH

A. Prior to the commencement of work, the Contractor shall verify the location and depth of all utilities, including service laterals and service connections, which have been indicated on the plans or marked by the respective owners and which may affect or be affected by its operations.

B. All utilities designated on the plans to be protected in place shall be carefully uncovered if located within the lines of excavation and time shall be allowed for the Inspector or County

Representative to field check the location of such utilities to make certain that they will not interfere with maintenance. In the event a utility conflict exists, the County will either arrange for utility owner to relocate the utility or adjust grade and/or alignment of the proposed improvement.

In the event any such facility should be disturbed or damaged, the Contractor shall at once make restorations to the satisfaction of the owner, or arrange with the owner to make restorations, at no cost to the County. Any delays or reconstruction of maintenance resulting from the Contractor's failure to verify utility locations and depths shall be made at the Contractor's expense.

C. Full compensation for “Verification of Utility Location and Depth” shall be considered as included in the various contract items of work involved and no additional compensation will be allowed.

W. EXISTING FACILITIES

A. This work shall consist of removing, relocating, or protecting existing facilities which interfere with maintenance. Removed facilities shall be disposed of, salvaged, relocated as specified in this
