RE:

Dear Mr. Riter,
RITOCH-POWELL & ASSOCIATES (an Ardurra Company) is submitting attached Scope of Work and 
Fee Derivation for additional T&M compensation to provide construction administration, management 
and inspection services for the Chandler Heights Road project.
Our additional compensation totaling $288,991.78 for this contract modification is necessary to match 
the contractor’s projected construction schedule to achieve Substantial Completion by September 9, 
2024 and Final Completion by November 8, 2024. Contrctor’s schedule extension increases our CM 
services contract by twenty eight (28) weeks through January 31, 2025 to complete contract close-out 
activities that include record drawings, AOCs, final contract invoices, etc. This contract modification is for 
construction administration during the additional contract time and sixteen (16) weeks of on-site 
inspection services.
We sincerely appreciate the opportunity to continue our City of Chandler relationships executing final 
design, construction administration, and inspection services and look forward to completing this 
construction project.
Respectfully submitted,

CONSTRUCTION MANAGEMENT 
SCOPE OF SERVICES 
CHANDLER HEIGHTS ROAD (McQUEEN RD TO GILBERT RD) 
CONTRACT MODIFICATION #4 
 
 
PROJECT UNDERSTANDING 
 
The current scope of work was based off the Chandler Heights Road Contractor Change Order 
Number one which extended the Substantial Completion Date to 5/3/2024 and the Final 
Completion Date to 7/2/2024. The Contractor will not be able to meet either of these dates. The 
delays to the project have been outside of Kimley-Horn’s control and require additional effort 
above and beyond the current contract scope of work. At the request of Ardurra and the City of 
Chandler, this contract modification has been prepared so that Kimley-Horn provides the 
additional effort anticipated to reach the projected Substantial Completion Date of 9/9/24 and the 
projected Final Completion date of 11/8/24.

H.  Task 2.8 Public Outreach 
i. Consultant will coordinate with City and Ardurra for additional public outreach 
services. Additional public outreach is needed during the additional seventeen 
(17) weeks to reach substantial completion.  
I. Task 2.9 Unforeseen Conditions 
i. Consultant has expended extensive out of scope effort attending meetings, 
reviewing and sending letters, and conducting site visits related to the 
Contractor’s inability to manage and construct the project appropriately. There 
are three items which have required additional effort outside the current 
contract. The change in Contractor key personnel, out of compliance traffic 
signals at Adams Ave, the out of compliance pavement east of Cooper, and the 
unforeseen sinkhole west of Senate. 
1. Change in Contractor key personnel. Early in 2024 the Contractor lost 
their project manager, superintendent, project engineer, grading 
foreman, and a majority of the concrete crew. The Consultant 
conducted multiple site visits and meetings in an attempt to get the 
new staff familiar with the project and to train new Contractor staff on 
federal processes such as pay applications, material certifications, time 
and material work, and partnering.  
2. Traffic Signal at Adams. The Contractor installed two traffic signals at 
Adams Ave which were not in compliance with the construction 
documents. Consultant conducted multiple site visits and coordination 
meetings to discuss and review the out of compliance signal. Meetings 
and coordination included Consultant staff from the traffic signal group 
and the structural group to review and respond to letters sent by the 
Contractor. 
3. East side pavement. Approximately 4,200 linear feet of asphalt was 
paved out of compliance with the project documents east of Cooper. 
Consultant 
conducted 
multiple 
site 
visits, 
reviewed 
multiple 
remediation actions from the Contractor, attended multiple meetings, 
and provided remediation recommendations to help resolve the issue.  
3. 
CONSTRUCTION ADMINISTRATION (NOT USED)

up to two (2) site visit per month for four (4) hours per visit for up to four (4) 
months for the Project Engineer remains outside the current scope of work. 
Consultant assumes up to two (2) site visits per week for four (4) hours per visit 
for up to seventeen (17) weeks for the Senior Project Manager remain outside 
of the current scope of work.  Consultant will make these visits to observe the 
progress of the work.  Observations will not be exhaustive or extend to every 
aspect of Contractor's work, but will be limited to spot checking, and similar 
methods of general observation.  Based on the site visits, Consultant will 
evaluate whether Contractor's work is generally proceeding in accordance 
with the Contract Document and keep Client informed of the general progress 
of the work. 
B. Task 4.2 Project Closeout  (NOT USED) 
 
5. 
UTILITY COORDINATION (NOT USED) 
 
6. 
MATERIALS TESTING 
A. Task 6.1 Quality Control (QC) Test Program 
i. The CIP Contractor submits weekly QC reports showing all field and lab testing 
data. Consultant will reviews these weekly reports to verify Contractor’s 
Quality Control material test type and frequencies are consistent with City, 
MAG, and ADOT requirements; review and evaluate Contractor’s QC test 
schedule and provide recommendations on acceptance; and review and 
evaluate all Contractor sampling, test, and inspection results for conformance 
with construction documents. The Contractor time extension requires up to 
seventeen (17) additional weekly QC report reviews. 
B. Task 6.2 Quality Assurance (QA) Test Program 
i. Consultant will review QA testing is consistent with Contractor’s QC testing 
results. The Contractor time extension requires up to seventeen (17) 
additional weekly QA report reviews. 
C. Task 6.3 Material Certifications   
i. Consultant will review and verify material certifications are met including “Buy 
America” requirements and prepare and maintain materials certificate and 
“Buy America” requirement submittal log. The Contactor time extension has 
resulted in the Contractor submitting more material certifications with less 
material quantity per submittal. This requires up to four (4) months of 
additional material certification reviews and log preparation. 
 
7. 
RECORD DRAWINGS 
A. Task 7.1 Record Drawings 
i. Due to multiple changes in Contractor’s key personnel over the course of the 
project and the lack of current Contractor project management, we anticipate 
additional effort to finalize record drawings will be required.
