RE: 
Arrowhead Sewer Line Phase 1.1 – WAS Line Realignment 
Project #202104.1 
Change Order #2 – Request for additional funds and expenditure of remaining City 
Allowance 
Dear Mr. Alter, 
We appreciate the opportunity to work with you and the City of Glendale on the CA&I Services for the 
WAS Line Realignment portion of the Arrowhead Sewer Line Phase 1.1 project. 
A contract change order of $3,878 and expenditure of the City’s $20,000 contract allowance is 
requested for additional costs that Dibble and our subconsultant, Dibble CM, have incurred during 
construction.   
Dibble’s CA&I Services scope and fee – and by extension Dibble CM’s scope and fee – was based on a 
construction duration of 11 weeks from NTP to final completion.  B&F’s NTP was September 2, 2025, 
establishing November 18, 2025 as the end date for Dibble CM’s services.  B&F’s latest look-ahead 
schedule provided on December 8 indicates a completion date of December 19, 2025, approximately 4 
weeks beyond the originally proposed end date.  Dibble CM estimates an additional 52 hours of 
inspection at a cost of $11,214 will be required because of the extended time. 
Dibble incurred $12,664 in additional costs associated with submittal and RFI reviews and structural 
inspections associated with the installation of the WAS line.  The request is itemized below. 
-
Task 230 provided for 20 submittals at 2 hours (total labor) per submittal.  To date, there have 
been 27 submittals that required approximately 2.5 hours per submittal on average.  The total 
cost for these reviews is $12,296 versus the $7,640 included in the initial fee.  Therefore, I am 
requesting $4,656 from the allowance to cover the additional cost.
-
Task 240 provided for 4 RFIs at 4 hours (total labor) per RFI.  To date, there have been 10 RFIs 
that required approximately 2.6 hours (total labor) per submittal on average.  The total cost for 
these reviews is $4,936 versus the $3,056 included in the initial fee.  Therefore, I am requesting
$1,880 from the allowance to cover the additional cost.
-
Task 440 provided for 1 site inspection and associated report generation at 10 hours for 
installation of the structural anchors supporting the WAS line under the bridge.  The time 
required for installation of the anchors resulted in four site visits, each of which was

2
documented with an individual report, resulting in 32 hours at a cost of $8,000 versus the 
$1,872 included in the initial fee.  Therefore, I am requesting $6,128 from the allowance 
to cover the additional cost. 
The total additional costs incurred by Dibble and Dibble CM are $23,878.  Approval of this request will 
expend the $20,000 City Contract Allowance and increase the total CA&I fee by $3,878 to $156,716 
for the WAS Line Realignment portion of the Arrowhead Sewer Line Phase 1.1 project. Accounting for 
Change Order #1, the overall CA&I fee associated with the Arrowhead Sewer Line Phase 1.1 project 
will increase by $43,858 from $388,772 to $432,630.  I appreciate your consideration and am available 
to discuss further. 
Sincerely, 
Eric French, PE
