Asset Management 101
• Governmental Accounting Standards Board Statement No. 34 (GASB
34) requires that state and local governments report the value of their
infrastructure assets
o Phase I- Need to locate and catalogue all assets
o Phase II- Need to present the current value of infrastructure
assets
• Value of infrastructure asset depends on remaining service life
• Remaining service life is based on current condition state
4
GASB 34 Requires Utilities to:
• Maintain an up-to-date inventory of eligible infrastructure assets.
• Perform condition assessments of eligible infrastructure assets at least
every three years, using a replicable basis of measurement and
measurement scale.
• Summarize the results, noting any factors that may influence trends in
the information reported.
• Estimate each year the annual amount to maintain and preserve the
eligible infrastructure assets at or above a prescribed level.
• Compare the estimated maintenance cost of infrastructure assets at or
above the established condition level based on amounts spent during
each of the past five reporting periods.

DIAMS – Background
• DIAMS integrates drainage asset data obtained from field
inspections into a comprehensive information, analysis and mapping
system for electronically documenting, monitoring, and managing
these assets.
• DIAMS manages the database of culvert and storm drain pipe asset
inventories to assist with verifying locations, tracking condition
states, assessing performance, scheduling inspection and
maintenance activities, and selecting and budgeting rehabilitation
and replacement jobs.

Pipe Treatment Decision-Making
Process
•
DIAMS will automatically calculate the standardized pipe treatment costs for
the current pipe segment under review; according to 1) pipe age 2)
condition state 3) segment length 4) diameter and 5) pipe material
type, (e.g., Cost of New installation, Cost of Inspection/Cleaning cost, Cost
of Rehabilitation and Cost of Replacement).
•
Standardized costs are calculated based on the 2011 NJDOT Engineer’s
Estimate – Maintenance Drainage Repair Contract unit costs. The unit
cost table is a template which can be modified at any time in the DIAMS
settings based on previous year’s bids, working experiences etc.
Additionally, new contract items can be added or deleted if not used.
•
Itemized treatment costs may also be set by the user for the particular pipe.
DIAMS will use the existing values until they have been changed.

If further refinements for estimated treatment costs are required,
click ‘Estimate Costs’ button to open the Cost Estimation Form to
make cost justification. Knowing the actual total treatment costs,
users can directly input these total costs into the cost fields on the
form. Or, click one of the ‘Help’ buttons next to the cost fields to
bring up a cost analysis template form.

In cases when both the pipe current condition state and pipe age are
known, the Treatment Techniques Form will open. This form displays the
system recommended techniques, and the current and improved condition
states that are retrieved from the treatment policy tables. Users can
select the desired technique listed in the sub-form.

In the Treatment Justification Form, DIAMS will automatically compare the treatment
technique costs and notify the user if the selected action is justified. The user can
make a choice to either accept the system recommendation or reject. There may be
several actions justified. Only one action can be selected. If a justified action is
selected, the recommend treatment technique will be saved in the decision comment
text box and transferred back to the database. The decision will show up on the Pipe
Assessment Form for the user to review.

Financial Analysis Module
•
•
After the treatment techniques for the pipe segments have been
determined, the user can define ‘maintenance projects’. Here, a
‘maintenance project’ is defined as a group of pipe treatment jobs
to be considered within a certain allocated total budget.
With DIAMS, users can search the optimal or near optimal
solutions for the budget allocation among these pipe treatment
jobs. The pipe assessment and optimization process are the core
components of DIAMS pipe financial analysis module.

Pipe Project Optimization
• The Pipe Project Optimization Form consists of four
major components:
1. The system evaluates the Project Input Data and
summarizes its major attributions:
a. How many pipe segments are in the project?
b. What is the total capital required by their treatment
jobs?
c. How many are pre-fixed jobs as well as the
minimum required capital for these pre-fixed jobs?
2. In the upper sub-form, the Project Input Data Set is
displayed. In the lower sub-form, the solution results will
be displayed after running calculation algorithms. At the
bottom, a short label will state the final solution summary
values.

Pipe segments assigned treatment techniques will be listed on the
form. Pipes that were already treated or those with decisions of ‘Not
Determined’ or ‘Do nothing’ are omitted.
Users can select a group of pipes as the elements of a project by
clicking the box under ‘Selected’. Users can also decide if some of the
selected segments must be included in the optimal solution regardless
of their treatment cost by checking ‘Pre-fixed’.

Summary and Conclusions
•
•
•
•
•
•
•
A drainage identification, analysis and mapping system that will comply
with both requirements stipulated by the Governmental Accounting
Standards Board (GASB-34) and new federal storm water regulations was
developed.
It maintains an up-to-date inventory of eligible infrastructure assetspipes, inlet/outlet structures, manufactured treatment devices and
outfalls.
It consists of three major computer software components: databases,
user interfaces, and a data administration module.
It contains a financial analysis module capable of analyzing decisions to
inspect, rehabilitate/replace or do nothing at both project and network
levels.
At the project level this is achieved by comparing inspection and/or
rehabilitation/replacement costs with risks and costs associated with
failure.
At the network level, the associated costs are optimized to meet annual
maintenance budget allocations by prioritizing culverts needing
inspection and rehabilitation/replacement
It has an online data submission and quality control module for
inspection data.
