Abstract: Municipal Infrastructure Investment Planning (MIIP)
The objectives of the MIIP project are to identify, evaluate and develop tools, procedures, and practices that can help infrastructure managers make strategic and cost-effective planning and management decisions.
The project is now in its final months and many of the project deliverables are already available to the general public. These include: a survey of municipal infrastructure assets in Canada, a primer on strategic asset management, a report on geographic information systems for municipalities, case studies of municipal asset management, an evaluation of sewer condition assessment protocols, a report on social costs of infrastructure rehabilitation, reviews of asset management software systems, a report on opportunities for research in asset management, an analysis of the state of Canadian sewers and their remaining service life, and a framework for municipal infrastructure management for Canadian municipalities.
There is strong interest from the majority of the current MIIP members to continue with a Phase II of the project. Areas of interest for MIIP Phase II include: decision support tools for asset management, modelling the deterioration of buried utilities, and a generalized framework for municipal infrastructure management .
The current MIIP contributors are the cities of Calgary, Edmonton, Hamilton, Ottawa, Prince George, and Regina, the regional municipalities of Durham, Halton, and Niagara, and the Department of National Defence.

• The State of Canadian Sewers – An Analysis of Asset Inventory and Condition
– One of most comprehensive sewer inventory and assessment surveys – Peak decade of growth for Canadian sewers was 1970
– Small diameter pipes (≤ 600 mm) comprised 91% of all pipes – Most pipes were Vitrified Clay
– PVC has become the material of choice for newer pipes – Concrete was the most used material for larger diameter pipes – Joint defects were most prevalent in PVC and VC pipes – Regression analysis used to predict sanitary sewer pipe service life
(105 to 130 years)
– Markov transition matrices were developed for small diameter pipes (any material) as well as matrices for AC, CO and VC pipes – Not enough data to develop matrices for PVC pipes

•General rules exist only in practice today (6 Whats):
– What do you own? – What is it worth? – What is deferred? – What is the condition? – What is remaining service life? – What do you fix first?

• A Framework for Municipal Infrastructure Management for
Canadian Municipalities (Dec 05)
– Part 1 details “top level” processes for municipal infrastructure management (MIM);
• Primarily deals with decision-making
• Outlines the framework for senior managers and council
– Part 2 identifies the details of the “WHAT” and “HOW”
• Outlines implementation issues faced by practitioners • Describes available technologies to address the opportunities and
suggests potential solutions
– Ready in December 2005
MIM Framework- Part 1
• Framework is based on extensive “Value Engineering”
exercises by MIIP members at a number of meetings
Inventory Performance
Service Life Life Cycle Cost
Criticality
Technical Ranking
• To properly determine the “Technical Ranking” need to:
– Identify inventory – Predict performance – Estimate service life – Calculate LCC – Determine Criticality
• All 5 facets are described
– Parts 1 and 2
MIM Framework- Part 1
•
For each facet must identify processes
Select Protocols Itemize Assets Inspect Assets Rate Assets Forecast Needs Integrate Needs Recommend Resources Optimize Investment 1. Select Protocols 2. Itemize Assets 3. Inspect Assets 4. Rate Assets 5. Forecast Needs 6. Integrate Needs 7. Recommend Resources 8. Optimize Investment
•
All 8 processes are described
for each facet
MIM Framework- Part 1
• Describes overall goal as an ever-tightening spiral
Select Protocols Optimize Investment
• Each Process level looking at:
• Inventory • Performance • Service Life • LCC • Criticality
MIM Framework- Part 2

These protocols might even vary within the organization, as some protocols could have been implemented in one region and not another one. This process is fundamental to the entire Framework as it structures the Framework and determines which protocols need to be implemented. Although this task appears at the beginning of the major process, it can only be implemented after all the protocols for the various facets have been selected. Once the specific protocols have been established and which data are to be collected, then and only then can the IT framework be selected. Many municipalities could be restricted as to how they implement their MIM system owing to legacy software constraints, financial considerations and human resource issues.
Recommend level of funding required to meet initial technical requirements Could be several options min, optimum, maximum •-individual asset class based and coordinate to get total •- protect program vs project •Operating and capital budgets - Standardize asset classes, so that average is average regardless of asset
Provide better definition required, “harmonize” with common data structure.
