Section 13 – Existing Facilities

Attention is directed to Section 12, “Construction Area Traffic Control”, of these

Specifications regarding the maintenance of existing traffic control signs.

13-2.03 Survey Monuments

Existing survey monuments and markers shown on the Plans or found during progress of

the Work shall be preserved. (See Section 5-9.02, “Survey Monuments”, of these

Specifications.) Survey monuments and markers are hereinafter referred to as “monuments.”

The Contractor shall notify the Agency of any monument encountered, and shall not remove or

damage said monument until the monument can be cross referenced and surveyed by the

Agency. The Contractor shall allow a minimum of one (1) Working Day for such referencing to

be accomplished. When notified by the Agency that the cross-referencing has been completed,

the monument may then be removed. The Contractor is not responsible for the replacement of

any monument that has been cross-referenced and surveyed by the Agency, as specified

above. If the Contractor fails to notify the Agency as specified above, or removes or damages

any monument that is not in direct conflict with the Work, all referencing, resurvey, and

replacement of the monument shall be at the Contractor’s expense.

13-2.04 Landscaping Improvements

Existing landscape improvements and appurtenances including irrigation pipes, gate valves,

remote control valves, sprinkler heads, hose bibs, automatic irrigation controllers, and yard

lighting systems that interfere with the Work shall be removed. Irrigation pipes shall be capped

at the right-of-way line or easement line, unless otherwise shown or specified in the Contract.

Irrigation systems that are affected by the Work that provide irrigation to existing landscaping

that is not to be removed as part of the Work shall be replumbed and rewired, when necessary,

to be operational within five (5) Working Days of being affected by the Work. Care shall be

taken to guarantee that the system is plumbed consistent with appropriate design pressure and

flow. All irrigation lines shall be flushed and free of dirt and debris prior to re-plumbing. The

Contractor shall make arrangements with the abutting property owner to salvage and stockpile

any materials removed during the Contractor’s operations. On projects for underground

construction of sewer, drainage, or water facilities in public utility easements or other

easements, existing landscape improvements and appurtenances shall be reconstructed to their

original location and condition, unless otherwise shown or specified in the Contract.

Existing plant material (i.e. trees, shrubs, ground cover and lawn) within the area affected by

the Work and designated for removal shall be removed per Section 15, “Clearing and

Grubbing”, of these Specifications.

13-2.05 Abandoned Underground Facilities

All abandoned pipes, conduits, and other abandoned structures within two feet (2’) below

the roadway subgrade shall be removed and disposed of. Pipes that are lower than two feet (2’)

below the roadway subgrade shall either be removed or the ends plugged with concrete, at the

option of the Contractor, unless specified otherwise in the Contract. Pipe ends shall be plugged

in accordance with Section 15-1.04, “Abandonment of Pipes and Manholes”, of these

13-2.06 Drainage Facilities

The Contractor shall maintain existing drainage facilities, including ditches, during the Work.

Except where otherwise shown on the Plans, the Contractor shall re-establish the drainage

facilities to their original locations and in working condition as soon as possible after completing

work in the area. For remedial maintenance projects or improvement projects in established

areas, the Contractor shall coordinate the work so that storm drain systems are fully operational

at the end of each Working Day. No runoff shall be allowed to flow unconfined through any

trenches or excavations without approval of the Agency.
