AGENDA ITEM DETAILS
RECOMMENDATION:
City Staff are recommending that the Council approve two Change Order Requests for the Wellhouse No. 4 Water
Treatment Plant (WTP) project.
ARE YOU SEEKING APPROVAL OF A CONTRACT? IS A PUBLIC HEARING REQUIRED?
No No
BACKGROUND/JUSTIFICATION:
The following table summarizes the change orders being submitted for Council consideration related to the Wellhouse
No. 4 Treatment Improvements project. Additional details on each change order are provided below.
Change Order
Request # Description Amount
015R1 Backwash Tank Roof Layout Modifications $18,914.39
021 Roofing Hardware Modifications $3,817.67
COR 015R1 - Backwash Tank Roof Layout Modifications
During construction, it was determined that modifications to the roofing system on the Backwash Reclaim Tank were
required. To ensure proper weather protection and consistency with the intended design, roof scuppers, new roof
crickets, roofing around tank chimneys for hatches, and plumbing vent penetrations details were added. This additional
work provides the complete roofing coverage required for proper construction and long-term performance.
This proposal reflects an increase of $18,914.39 to the construction contract for labor and materials associated with the
extended roofing system. Although the clarification occurred during construction, the work represents scope that, if
fully detailed, would have been included in the original Contractor’s bid price. AE2S has reviewed the Contractor’s cost
and considers it fair and reasonable.
COR 021 - Roofing Hardware Modifications
During construction, the Contractor raised concerns regarding the support system for the chemical room addition roof
mono truss bearing system. They proposed switching the bearing system from hangers to a ledger board to ensure
adequate securement to the existing Wellhouse split-face block wall. AE2S reviewed the suggestion and agreed that the
method would provide a better support system at a marginally increased cost.
This proposal reflects an increase of $3,817.67 to the construction contract for labor and materials associated with the
ledger board and roofing hardware installation.
The proposed net increase in project cost for these change orders is $22,732.06 to the construction contract. This
amount represents a 0.33% increase over the bid cost and would bring the total change order net increase to 1.86% for
the project. A contingency amount of 5.0% is included in the project budget and financing package.
The Public Works Subcommittee reviewed this information at their November 19, 2025, meeting and recommended
consideration of approval by the City Council.
