G. Inspection by public agencies.

• Provide proper facilities for such access and inspection.

• Flow of irrigation water in the Ditch, which is shown on the Drawings, and runs through the project site, must not be interrupted during the period April 15 through August 1.

Main park road utility trenching and installation, culvert work or temporary culvert installation for construction access will need to be completed outside this time window.

The Owner will allow the Contractor to use the two track drive northeast of the property as a construction access to the site.

• The new potable waterlines will not be live and on-line until plant treatment processes, pumping systems and well improvements have reached Substantial Completion.

• The existing elevated tank shall remain in-service, as-is, with its availability to provide potable water to the distribution system until the Wells Nos. 5 and 6 are brought on-line to feed the new WTP and the existing transmission line from the existing elevated tank is cut and capped.

• On a somewhat flexible schedule, proceed with well/wellhouse improvements, including any needed well rehabilitation note, however, that Well No. 6’s pump cannot be installed until the conditions prior-noted have been met. Also, the Contractor shall minimize the time that Well No. 5 is the only well able to feed the existing elevated tank and no potable well can feed the potable system directly. Therefore, the Contractor shall have Well No. 6 ready to bring on-line within two (2) weeks after the WTP treatment process, pumping and control/communication systems reach Substantial Completion and the potable water line is cut and capped.

• Work will not begin on Well No. 6 and its wellhouse without written approval from Owner. It is intended that Well No. 5, in addition to Well No. 6, be available to directly feed the potable system through the peak summer demand season in 2017. Work on Well No. 6 to be delayed until after this date includes new pump installation, new VFD and controls/telemetry work. Contractor may wish to schedule Well No. 6 inspection and potential rehab work (via Change Order only) during same mobilization.

• Complete all Wells Nos. 5 and 6 work and associated Ethernet radio and controls work in-time for it to supply influent water to the new water plant for start-up.

• Complete tie-ins for plant raw water line and both finished water lines.

• Coordinate with Owner regarding all plant commissioning activities, especially operations relating to alternating use of Wells Nos. 5 and 6 to feed plant for start-up.

• Commission new plant and obtain Engineer certification that Substantial Completion has been reached for all Well No. 6 improvements as well as all plant treatment process, pumping and communication/control systems with the following minor exceptions as related to eliminating potential cross connections between the backwash pond and the potable system:

• Obtain Substantial Completion certification for overall project and address Substantial Completion walkthrough punchlist items.

• Hold Final Acceptance walkthrough and address Final Acceptance punchlist items.

Apply for Final Payment and close-out project.
