A
  • Safe surface to travel on
  • Smooth surface to travel on
  • Surface for a comfortable driving experience
  • User experience
20
Q

What are some technical LOS used for pavements?

A
  • Structure that protects the subgrade from excessive stress
  • Structure that protects the subgrade from moisture
  • Structure that provides skid resistance
  • Structure protects local services
  • etc.
21
Q

What is NZ’s largest infrastructure asset?

A

Pavement

22
Q

What are technical Performance Measures that could be formed for a state highway road in NZ?

A

Quality
Quantity
Availability
Legislative requirements
Maintainability
etc.

23
Q

What functional (consumers) PMs could be formed for a state highway road in NZ?

A

Customer service
Facilities
Responsiveness
Willingness to help
Assurance
Caring
Empathy
Trust and confidence
etc.

24
Q

What are the 4 Social Key Performance Measures or Social Key Performance Indicators (S-KPIs)?

A

Road safety
Environment
Socio-economy
Availability and disturbance

25
Q

How do we compare two roads? There are 3 approaches.

A
  1. Brute force with weighted expert opinion.
  2. Linear comparison
  3. Using pavement detorioration modelling for scoring
26
Q

What is the aim of maintenance?

A

Lower the lifecycle cost and use the money generated to extend the reach within the program.

27
Q

What are the different types of actions you can take in a Pavement Maintenance Plan?

A
  1. Maintenance: planned
    - strategic: early in pavement life
    - emergent: reduce need to perform reactive repair
  2. Reactive: unplanned, immediate needs. Restore to serviceable condition.
28
Q

What are the different types of chip seal?

A

Single chip
Double chip
Racked in seal
Cape seal
Inverted seal
Sandwich seal
Geotextile reinforced soil

29
Q

What are independent systems?

A

Do not share any processes or data

30
Q

What are interfaced systems?

A

Simply connected systems/subsystems that can exchange information through a common boundary. Share data but no processes.

31
Q

What are interoperable systems?

A

Provide and accept services from other systems and use services exchanged to enable them to operate effectively together. Limited sharing of processes and data.

32
Q

What are integrated systems?

A

Tightly coupled interconnection of different, highly specialised devices, systems/subsystems, into a broader system providing complex functions. Close interactions between components.

The systems share many processes and data.

33
Q

What is a Phase 1: Conceptual Data model in asset management?

A
  • High level definition of main model entities and the relationships between them.
  • a.k.a. “High-level data model”
34
Q

What is a Phase 2: Logical Data model in asset management?

A
  • More detailed design. Intermediary between conceptual and physical design.
  • Include specific information that allows coding within a database
35
Q

What is a Phase 3: Physical Data model in asset management?

A
  • Includes specifics that facilitate coding within a specific DataBase Management System (DBMS). Includes internal storage structures, access paths, file organisations, …
36
Q

How do we quantify load on our roads to use in models?

A

Equivalent Standard Axle (ESAL)
No. of standard axles for same damage =
[Load_on_axle_group/Appropriate_load]^EXP

Appropriate load from tables
EXP depends on type of pavement usually 4

37
Q

What is the role of infrastructure?

A

Economic productivity. Pressured by:
- communication
- education
- dependence
- health etc

38
Q

What are the key components of AM plan?

A
  1. Asset management policy
  2. Define LOS and performance
  3. Forecast demand
  4. Understand asset base
  5. Asess condition
  6. Identify asset and business risk
39
Q

What is an output?

A

Tangible product. Feature. e.g. new hospital building

40
Q

What is an outcome?

A

Desired operational unit. e.g. additional hospital now operational

41
Q

What is a benefit?

A

Measurable gain to stakeholder. e.g. reduce elective surgery waiting list by X%

42
Q

Discuss the importance of the 5 key principles of Asset Management with respect to risk.

A
  1. Policy driven: decisions reflect policy goals & objectives that define desired system condition and service levels
  2. Performance based: clear measures of performance and target service levels are established
  3. Options evaluated: comprehensive choices & tradeoffs are examined at each level of DM
  4. Decision based on quality information: management systems and tools are used
  5. Clear accountability: performance results are montored and repeated.

DM = decision making

43
Q

What are some main areas of concern for AM?

A
  • limited knowledge and information available on conditions of assets
  • financial provisions are insufficient to meet long-term expenditure
  • need long-term perspectives
44
Q

Why is chip seal used commonly in NZ?

A
  • cheaper than asphalt but not as long-lasting
  • don’t have the traffic volume to justify using more expensive techniques
45
Q

What is the Zachman Framework?

A

A thinking tool to understand complex IT problems.
