Mr. Marc Stern
Dibble Engineering
3020 E. Camelback Rd., Suite 201
Phoenix, AZ 85016
Dear Marc:
MakPro Services, LLC (MakPro) is pleased to provide the following scope and cost estimate for
public outreach services during construction for the City of Chandler’s Dr. AJ Chandler Park
Improvements (CA2402.451). Construction is scheduled to begin in early 2026 and be complete
in December 2026, approximately one year. Public outreach is an important element in projects
such as this, that take place in Chandler’s downtown and require close communication with
downtown businesses. MakPro has a long history of working in Chandler’s downtown, and many
times, this small link is all that is needed to help a project run more smoothly.
There are a variety of public outreach tools which can be used to establish appropriate
communication with the effected stakeholders of a project. The services included in this scope
and fee are based on my experience with the City of Chandler and Downtown Chandler on
previous projects. This estimate is based on an estimated 1-year construction schedule. In
addition, the public outreach services have been categorized into tasks; however, adjusting one
task may require adjustment of other tasks as there are economies of scale and efficiencies
embedded in the cost estimate.
Please take a moment to review this scope and cost estimate and if I’ve missed or
misunderstood any of the project characteristics, or if you’d like to customize this proposal in
some other way, please let me know.
Task 1: Pre-Construction and Project Progress Meetings, and Team Communication
MakPro will prepare for and attend the pre-construction meeting and weekly progress meetings
during construction (1 year ~ 52 meetings), as well as participate in ongoing team communica-
tions throughout the project.
Task 2: Construction Notice & Stakeholder Communications
Prior to start of construction, MakPro shall develop, print, coordinate and mail one printed pre-
construction notice to project area stakeholders, and property owners directly adjacent to the
work area. In addition, MakPro will coordinate with businesses more directly impacted by the
work, and attend, as needed, DCCP Merchant Meetings to provide information on the project.

Public Outreach Services – Dr. AJ Chandler Park Improvements (CA2402.451)
Task 3: Project Communications
•
Project Webpage: MakPro shall maintain a project webpage on ChandlerAz.gov for the
project, which is capable of multilingual information, and will include information related to
the project construction schedule and how to contact the project team. The site will be
updated with any new information on a regular basis.
•
Project E-Updates: MakPro shall prepare regular email updates, approximately every 2-3
weeks or to convey significant project milestones, with upcoming construction schedule
information, which will be shared with the DCCP, and we’ll also maintain a distribution list of
those interested in the project.
•
Hotline: MakPro shall maintain a 24-hour bilingual project hotline to respond to inquiries or
complaints, maintain a call log and coordinate with the project team to respond to calls.
Provided below are the estimated hours for each task, as well as printing and postage costs:

Grand Total

The total cost for public outreach services as identified above based on a 1-year project
schedule should not exceed $18,700.00. This cost estimate assumes a labor rate of
$120/hour for principal and $100/hour for associate hours. The project hotline is billed at
$300/mo for availability 24/7, and scheduled progress meetings are assumed to be virtual, and
have a one-hour minimum. Also, this estimate incorporates efficiencies from one task/activity to
another, so removal of an activity may require an adjustment of hours in other activities.
This proposal assumes any displays, exhibits, engineering designs or details, required for public
meetings or information will be provided by the owner, construction manager, or contractor.
MakPro is not responsible for documenting existing property conditions, project signage, traffic
signage, or distribution of direct door hanger notifications which may be required to
accommodate the contractor’s work (e.g., water service disruptions). Changes of substance to
this proposal during the project may affect the final cost.
Thank you for the opportunity to work with you and the City of Chandler on this project.
Should you have questions or need additional information related to this proposal, please feel
free to contact me at (480) 890-1927.
Sincerely,
Teresa Makinen
