How to Implement Infrastructure

Overview of the Development Process

Certification Acceptance

Only communities that have Certification Acceptance status may use their own construction labor and equipment to accomplish their SRTS infrastructure projects.

These communities currently have Certification Acceptance status:

  • City of Phoenix
  • Maricopa County
  • City of Tucson
  • Pima County
  • City of Mesa
  • City of Tempe
  • City of Scottsdale
  • City of Chandler

If you are not one of the above communities, then ADOT will bid and administer your SRTS infrastructure project for you. In addition, communities that do not have Certification Acceptance status may not self-administer any portion of their SRTS project.

Project Timeline

After an SRTS project is awarded, the process normally takes 36 months from the date of the award date. The following project timeline is prescribed for SRTS projects and is illustrated in the flowchart below:

  • Project scoping kick-off meeting must occur within six months from the date of the annual workshop.
  • Project scoping must be completed within 12 months from the date of the annual workshop.
  • Environmental clearance must be obtained 18 months from the annual workshop. SRTS projects will normally not be allowed to proceed past Stage II (30 percent) design without environmental clearance if federal funds are used for project design.
  • Design must be completed and bid-ready, with utility and right-of-way clearances, 36 months from the date of the annual workshop.
  • Project bid award must be completed within six months of bid-ready.
Development Process Flowchart

A flowchart titled "Infrastructure Project Development Process" is available for download. This flowchart gives a summary of the necessary steps in completing your project.

Delayed Projects

A project can be cancelled if it does not make sufficient progress toward construction. Delays usually are a result of insufficient right of way to construct the project, insufficient funding, loss of local support, constructability issues, nonattainable environmental clearance, and conflicts with other planned improvements, to name a few.

Inactive Projects

Inactive projects are those that fail to meet the project development timelines. If the project development timelines are not met, a project cancellation notice will be issued within 30 days of failure to comply. The project sponsor may request an exception to the approved timeline if extenuating circumstances have led to project inactivity. ADOT's SRTS staff will provide the SRTS Advisory Committee with a recommendation on either approving or denying the extension. The Committee will then vote. A simple majority is required for action.

Project Activities

The list of project development activities cover three main areas: predesign, final design, and construction.

These are the predesign activities:

  • Attend project scoping kick-off meeting and determine who will bid the project.
  • Prepare initial and final scoping document (also called Project Assessment).
  • Prepare documentation for the environmental clearance. All documentation must be prepared in ADOT/Federal Highway Administration (FHWA) format.
  • Obtain approval for the final Project Assessment and the environmental document. After this step, you must get a notice to proceed from ADOT to begin incurring design costs if you intend to request reimbursement for those costs. Do not begin design until you get a written notice to proceed from the ADOT Project Manager. Doing so will result in a portion of your costs not being eligible for reimbursement. Any design work anticipating the use of federal funds must be identified as such in the initial project application.

These are the final design activities:

  • Attend project design kick-off meeting and field review.
  • Submit Stage II (30 percent) plans, cost estimate, and materials/geotech reports for review. If federal money is used for design, the project cannot proceed past Stage II until environmental approval is granted.
  • Submit Stage III (60 percent) Plans, Specifications and Estimates (PS&E) for review and final materials memo. Specifications are due at this time along with all details.
  • Finalize the Joint Project Agreement (JPA). ADOT will prepare the JPA for local and state execution. Deposit local funds into the construction account.
  • Submit Stage IV (95 percent) PS&E.
  • Obtain utility and right of way clearances.
  • Submit final 100 percent PS&E and request for federal funding for construction.

These are the construction activities:

  • Advertise for bids. ADOT will perform this function unless the sponsor has certification acceptance.
  • Begin project construction. ADOT will administer construction unless the sponsor has certification acceptance.
  • Perform billing activities and project close-out by ADOT unless the sponsor has been approved by FHWA/ADOT for Certification Acceptance.
