OVerview.
The City undertook its current pavement management program in the
summer of 1994. At that time a comprehensive street condition survey
was conducted in order to assign pavement condition rankings to the
city's roadway system. PCI's (Pavement Condition Index) were
established as an integral part of the computerized management program
to facilitate budgeting and roadway maintenance policies. After the
initial 3-year cycle, updated PCI's now need to be applied to the data
base.
primarv Issues to consider.
o Why is an update necessary?
At the time of pavement management's inauguration, the
consultant and staff advised Council that future surveys would
be necessary to provide the most accurate budget analyses and
maintenance strategies. The proposed survey covers all City
streets except those seal coated in 1996. In the future 3-year
cycles staff is advised that surveys will be of much reduced
scope and cost.
o What are costs and source of funding?
The attached Braun Intertec proposal calls for an expenditure
of $14,000.00 to survey roughly 45 miles of streets. This
program excludes the Interlachen Park neighborhood that
experienced seal coat applications in 1996.
staff proposes that funding should come from the budgeted
$40,000.00 seal coat program. That budget is felt to be in
excess of what the City needs to do in seal coating in 1997. A
recommended seal coat district that encompasses Hobby Acres and
campbell streets is being planned. A projected cost for that
program is roughly $15,000.00.
o Staff recommendation
Staff recommends authorizing funds for a comprehensive street
condition survey from the 1997 seal coat budget.

Dear Mr. Stadler:
Re: Proposal for Pavement Evaluation Services for Hopkins, Minnesota
Braun Intertec is pleased to offer pavement evaluation services to the City of Hopkins. As
you may recall, Braun Intertec performed a network level PCI survey on the entire Hopkins
pavement network in 1994. Braun Intertec strongly recommends a 1997 network level
resurvey to protect the City's significant investment of time and resources already devoted to
the system. A resurvey of the network will enable the City to maintain the integrity of the
pavement management system data and to ensure the accuracy of budget analysis projections.
Attached to this letter is a scope of services and related cost proposal. If after reviewing this
document, you have any questions or concerns regarding the project setup or services detailed
in this letter, please call me at 942-3051. Thank you for your continued interest in our
services. We look forward to working with you on this project.
Sincerely,

Braun Intertec proposes to provide the City of Hopkins with
Surface Condition Data Collection, Data Entry, and Performance Curve Analysis.
The Pavement Condition Index (pCl) data collection will cover approximately 45 of the total
48 centerline miles of the Hopkins pavement network. The surface condition survey proposed
in this task is a walking survey in which 100 percent of the street surface will be covered.
The collected data will be used to calculate a PCI for each segment (street block) that is
surveyed. The PCI will be correlated to existing pavement age data to determine multiple
pavement performance curves for the City of Hopkins. The cost estimates of this proposal
are based on the survey requirements and the initial overall network mileage estimates given
by the City of Hopkins.
At a minimum, the following pavement distress types will be collected as part of the PCI
Pavement Condition Survey:
Bituminous Pavement Distress Types
t> Alligator Cracking t> Polished Aggregate
t> Block Cracking t> Potholes
t> Cold Joint t> Ravelling
t> Corrugation t> Reflective Cracking
t> Depression t> Rutting
t> Edge Cracking t> Shoving
t> Flushing t> Skin Patching
t> Heaving t> Slippage Cracking
t> Longitudinal Cracking t> Temporary Patching
t> Permanent Patching t> Transverse Cracking
The streets to be included in this survey are:
Residential Streets:
38.22
Less Interlachen Neighborhood
(seal coated in 1996):
(3.00 )
State Aid Streets:
9.55
*Total Centerline Mileage:
44.77*
* This estimate does not include the 13 miles of the Hopkins Alley network.
As part of this task Braun Intertec will enter the collected data into the ICON pavement
management system and deliver this data to the City of Hopkins.
