Consideration and Approval of Contract: Annual Street Maintenance Chip Seal Program 2019

1. Approve the Annual Street Maintenance Chip Seal Program 2019 and execute a Construction Manager at Risk (CMAR) Contract with C and E Paving & Grading, LLC for a Guaranteed Maximum Price (GMP) of $2,033,450.55; and
2. Authorize the City Manager to execute the necessary documents.

The Public Works Streets Section maintains approximately 700 lane miles of roadway surface infrastructure for the citizens, regional community members, and visitors.  Roadways throughout the City vary in design and capacity.  In addition to automobile travel, all modes of transportation are integrated and encouraged within the right of way.  Modes of travels such as transit, bicycle, and pedestrian opportunities are prevalent and our Streets crews strives to provide transportation infrastructure that is well connected and as safe as possible for travel, regardless of the chosen mode.   

The City's annual Street Maintenance Chip Seal Program is an effort to improve aging infrastructure within our existing transportation network.  Planning efforts include an evaluation of the asphalt surface, edge treatments, recent overlay project sections, roads that meet maintence need, and road stripe engineering.  Once the identified needs are prioritized, Streets utilizes funding provided from two sources to address the needs.  The first source of revenue is Highway User Revenue Funds (HURF), or commonly referred to as the gas tax, a state shared revenue.  The second source of revenue provided is sales tax proceeds collected as a result of the 2014 voter approved Road Repair and Street Safety Program (RRSS).

This Council action, if approved, will allow Streets to deliver the Annual Street Maintenance Chip Seal Program 2019 utilizing local contractor C and E Paving & Grading, LLC and improve the community transportation infrastructure.

1.  Approve the Construction Manager at Risk Construction Contract with C and E Paving & Grading, LLC as proposed; or 2.  Request that the City continue to negotiate the scope of work and financial resources to a different outcome or expectation; or 3.  Reject the Construction Manager at Risk Contract and direct staff to pursue a different type of procurement delivery method and approach to work programming.

The City has established an annual program to maintain existing street pavements. The program includes three major elements: non-structural upgrades of asphalt overlay, minor concrete repairs, accessibility improvements including sidewalk/ramp replacement and chip sealing. 

The citizens of Flagstaff approved the Road Repair and Street Safety Maintenance Program (RRSS) (Prop. 406).  This is a dedicated sales tax providing funding of $100 million over 20 years.   The program has been aggressively addressing capital projects that have been identified to be in a high state of disrepair on the front end of the program with strong support for annual maintenance until the sales tax sunsets in 2034.

The chip seal streets are selected after evaluation of the street condition using pavement management asset software.  Each street pavement is assigned an overall condition index (OCI) based on the type and severity of the distress observed.  A pavement that has no distress is given an OCI of 100.  Each pavement distress such as cracking or roughness reduces the street’s OCI.  The street pavements are ranked by OCI and the pavements exhibiting the most severe distress are programmed for resurfacing treatments and improvements. In addition to overall ranking we use chip seal techniques to protect recently overlaid sections to prolong the life of the asphalt surface.

The Arizona State Legislature has authorized the use of Alternative Project Delivery Methods (APDM) as a method of project delivery. Included in these delivery methods the City of Flagstaff can select a construction team utilizing a Qualifications Based Selection process to procure construction services from a firm deemed most qualified to perform the work.  The enabling legislation also allows for provision of multiple Guaranteed Maximum Prices (GMP) under a single procurement.   

On July 3, 2018, Council approved award of the Design Phase Services Contract for the 2018, 2019 and 2020 programs to C and E Paving & Grading, LLC. in the amount of $ 113,794.00. This contract method provides the City various design phase services including program and budget evaluation, project scheduling, design document review, constructability review, detailed cost estimating, and preparation of final construction documents in coordination with our Public Works Senior Project Manager and our on-call civil engineering consultant Shepard-Wesnitzer Inc.

None.

Proposition 406 approved in 2104 has been a significant and positive influence on this maintenance program.  The community benefit of improving the overall road conditions saves countless staff hours for repair and thousands of dollars in temporary repairs and improves the overall roadway safety.  The overlay and chip seal projects have been aggressive and targeted our most degraded streets.  The projects can seem large in scope and they do cause some temporary disruption to our daily travel routines.  Acceptance of the temporary disruption and inconvenience can be challenging but the long-term benefits, efficiencies of bundling of our improvements is good stewardship.   Community notifications of construction programs are advertised and communicated via different mediums to provide general impacts and talking points as they relate to the project.

The community continues to support transportation related initiatives demonstrating a strong understanding of supporting a quality infrastructure.  We often receive citizen feedback and public participation to support our efforts of core service delivery.  In addition to the constant feedback, the voters approved the Road Repair Street Safety Program and the results have been positive.
