Avenue and Center Turn Lane Expansion

Contract #: 2018-034 Change Order #: 12

Request

: | To Establish Change Order No. 12 for full and complete compensation to the Contractor for all

inefficiencies and financial damages their subcontractor Incurred as a result of utility conflicts
encountered during construction of a SRP Irrigation 42” pipeline and for the performance of
extra work as directed.

Change
Order
Reason:

Per plan, the widening of 83rd Avenue to the south of MC85, between Stations 404+00 and
412+00 caused a section of existing SRP Irrigation 42” pipeline currently outside of the
roadway to be within the new roadway widening limits. Therefore, this 735-foot-long section
of Class Ill RGRCP pipeline was to be replaced with new stronger Class V RGRCP on the same
vertical line and grade.

During construction, it was discovered that the designed vertical line and grade of the new
pipeline was set to a deeper depth than the existing pipeline. Therefore, two utility crossing,
Southwest Gas and CenturyLink, coincidently not shown on the plans, which crossed
underneath the existing pipeline, were now in direct conflict with the new pipeline. This
caused delays resulting in standby cost for equipment and inefficiencies for the crew, which
resulted in this entire operation taking four days longer to complete. This change order
compensates the subcontractor for the equipment idle time and impacts to their productivity
for an average manpower and equipment cost of four crew days.

This change order also compensates the same subcontractor, fully and completely, for
performance of additional work as directed on other existing SRP Irrigation infrastructure on
83rd Avenue, south of MC85, This work included pavement removal, irrigation pipeline and
structure excavation, the construction of a 42” RGRCP pipe collar, and cement slurry backfill to
pavement subgrade.
