Maricopa County Department of Transportation
ATTACHMENT A (Change Order Scope)
TT0495 Project Name: Lower Buckeye Rd (71st Ave to 67% Ave)
2022-011 Change Order#: 22

Reason:

This change order is necessary to compensate the Contractor for the additional overhead, quality
control and traffic control costs associated with extended construction time due to substantial
differing site conditions. In addition, this change order will further modify the contract amount to
reflect the net difference between the bid quantities and the as-built quantities.

Description:

EXTENDED CONSTRUCTION TIME: Per the original TT0495 project plans, the entire north half of
Lower Buckeye Rd, including all of the 67 Ave work north of Lower Buckeye Rd, was designated to
be constructed in Phase 1. If construction had been allowed to proceed in this manner, the north
portion of Lower Buckeye Rd and north half of the 67 Ave intersection would have been complete
and open while Phase 2 on the south side was allowed to progress uninhibited. However, as
addressed in multiple previous TT0495 change orders and RFI responses, the mid-project addition of
a very large reinforced concrete drainage junction structure (MH19) 20 feet below the centerline of
the 67' Ave at the Lower Buckeye Rd intersection, in conjunction with several directly related fiber
optic and power utility conflicts, rendered the defined project phasing obsolete, and resulted in 2
months of delays. This initial delay imposed a cascading effect in that all of the asphalt rubber final
surface paving was subsequently pushed from the originally scheduled warm late September/early
October 2022 timeframe into the late November/early December 2022 timeframe where cold and wet
weather caused an additional 1 month of delay. Still, the project’s final walk-through was conducted
on December 19, 2022, after which substantial completion was granted by MCDOT, leaving only a few
minor items to complete. With the original and to date change order work substantially complete, the
City of Phoenix, who will ultimately annex this portion of Lower Buckeye Rd, introduced additional
new project scope as a condition of their final approval. The added scope involved the need for
redesigns, new submittals, and re-work of some project features that had already been built per the
originally approved plans. Completing this additional work resulted in an additional 2 months of
delays. For the reasons discussed above, change orders, throughout the project duration,
cumulatively extended the project construction end date from September 16, 2022 to March 24, 2023,
of which 5 months were a result of impacts caused by additional work not originally depicted in the
contract documents. Compensation for the extra work was fully accounted for in the previous 21
change orders, except for 2 months of Contractor overhead, 4 months of quality control, and 4 months
of additional traffic control.

A single new negotiated Lump Sum pay item in the amount of $127,719.23 is being created to provide
compensation for all additional overhead, quality control, and traffic control costs incurred by the
Contractor, except for that which was already included in previous change orders. No additional
contract time is being allowed for this change order.

FINAL QUANTITY ADJUSTMENT: The net change of existing bid item quantities is tabulated in the
Change Order 22 document. The cumulative cost of the net bid item changes is $ 227,802.88.
