Defining Asset Management

Infrastructure Asset Management is a strategic and systematic process of maintaining, operating, preserving and improving physical assets efficiently and effectively throughout their lifecycle.

It focuses on business and engineering practices to measure utilization, need and resource requirements with the objective of improving decision making in order to achieve the best possible outcomes.

Infrastructure Asset Management is Data Driven.

Inventory Development

An accurate inventory for each asset type and category is compiled and maintained.

The level of attribute detail captured for each asset is driven by several factors:

Provides the ability to

1. Define and assess relevant asset condition information.

2. Evaluate and establish optimal LOS goals for the asset.

3. Determine the appropriate M&O activity when condition thresholds are exceeded.

4. Track performance of the asset relevant to its expected lifecycle.

5. Identify the value of each asset and the sum of assets within each category.

6. Capture and correlate MOP costs specific to each asset.

Inventory Capture

The collection team creates an ArcPad map of the locations that contain the assets that need to be captured

The map is uploaded to a laptop to help the team navigate their way to the locations, and reference the existing drainage data.

Setting a Level of Service

What is Level of Service?

Level of Service (LOS) is defined and measured as a range from as‐built condition (no action required) to failed condition (urgent action required)

LOS goals are established with an objective to maintain or restore a level of condition that supports as‐designed operational safety and function for the least cost over the service‐life of the asset.

When resources allow, policy makers may choose a LOS goal that exceeds that delivered by the lowest‐lifecycle cost model; often to increase the aesthetic value of road right‐of‐ways.

Levels of service goals may be adjusted over time, but it is understood current LOS goals are established considering today’s needs, asset condition trends, budget constraints, and environmental priorities. 24

ROAD SHOULDERS

SECTION 32

ROAD SHOULDERS AND SIDEWALKS

32.100 SHOULDERS

32.110 GENERAL

Shoulders are those portions of the roadway contiguous with the traveled way that provide lateral support for the roadway base and surface courses. Road shoulders also may accommodate stopped vehicles for emergency use.

Properly constructed and maintained shoulders contribute to effective pavement preservation, free drainage of the pavement surface, and safe operation of the traveled way.

32.120 SHOULDER TYPES

Shoulders are of three (3) general types:

1. Earth or sod

2. Crushed stone or recycled asphalt product (RAP)

3. Hard surfaced 26


What is the range of condition that will deliver the desired results?

32.122 CRUSHED STONE OR RECYCLED ASPHALT PRODUCT (RAP) SHOULDERSShoulders of this type perform optimally for most road categories that experience moderate to low usage. Crushed

stone or RAP shoulders are and sturdier and less prone to rutting and deformation than earth and sod shoulders.

32.122.1 LEVELS OF SERVICE

High LOS: The crushed stone or RAP surface is routinely graded at a frequency that prevents the formation of edge ruts and grade deformations; that maintains lateral support of pavement edge; and, that maintains a 2% ‐ 4% slope to promote free drainage. The shoulder area is treated annually with an approved residual pesticide to inhibit vegetative growth.

Task codes utilized to achieve this LOS: 32A; 32CS; 32D; 32T; 71G

Lowest‐lifecycle cost LOS: The shoulder is graded as needed to remove edge ruts and grade deformations greater than 3 inches in depth; and, to maintain a 2% ‐ 4% slope to promote free drainage. Shoulder area is treated annually with an approved residual pesticide to inhibit vegetative growth; or, vegetative growth is controlled by mechanical mowing or manual cutting if shoulder is within an environmentally sensitive area.

Task codes utilized to achieve this LOS: 32A; 32CS; 32D; 32T; 71G

Low LOS: Site specific edge rutting and/or grade deformations are corrected by filling with crushed stone or RAP when conditions threaten safety and/or begin to damage another asset; e.g. – localized flooding, erosion, damage to pavement edge, sight distance.

Task codes utilized to achieve this LOS: 32A; 32CS; 32D; 32T; 71G27

LOS Summary

• Define the asset to an adequate level of detail

‐ Consider your database capabilities: data access, attribution details, and ID/segmentation schema

• Identify the asset’s role in delivering your mission objective

• Define the range of LOS from highest to lowest in terms that are clear and easily understood; and, that are support condition assessment and scheduling the work.

• LOS, condition assessment, and the M&O work are interdependent and must be easily adapted to change(system, performance measure results, info‐tech tools, political, etc.)
