Asset Management

Pregunta	Respuesta
Asset Definition	Object (physical or intangible) that has an identifiable value and useful life of greater than 12 months
Key Elements of Asset Management	- Finding required Level of Service - Knowing long term funding requirements -Asset condition and expected life - Knowing where money is spent - What assets are controlled/owned -Documentation of plans - Policy framework
Challenges and opportunities in Asset Management (competencies)	- Environment - Accounting - Financial - Emergencies - Maintenance - Management - Clients -Procurement - Innovation
Four features of asset management system	- Inventory (what you own) - Condition Measure (what shape is it in) - Prediction of future condition -Tools/Metrics for managing network
Why rate roads?	- Anticipate treatment windows - Measure condition -Measure of accuracy - Measure of network change
Types of condition measuring systems	Need a sustainable and descriptive system: Ordered state ratings - Criteria describes set of discrete, ordered states Index system - Relates physical measurements of distress extent and observer opinions to a numerical rating
Ways to predict of future conditions	- Rules of thumb (ie new asphalt lasting 14 years) - Traffic Volumes - Past experience = Modelling historic rating data - Forward looking models
Service Cycle	How big is the network? And how long will it take to service the entire network vs. it's life
Infrastructure Requirements	Needs to accommodate structural and environmental loading and be regularly maintained. Good management increases asset valuation, poor management loses it.
Three goals of infrastructure design	- Cost effective solution - Address deficiencies - Satisfy constraints Overall needs a thorough evaluation
ESAL	Equivalent number of 80 kN single axle loads
Key considerations for selection of feasible alternatives	- Condition assessment - Performance experience - Safety concerns - Capacity needs - Availability of resources - Cost effectiveness - Contractor availability
Network needs analysis and priority programming	Establish levels of service with trigger values in following areas: - Pavement Health - User costs - Maintenance costs - Depreciated value
Book Value	Current value based on replacement costs depreciated to current condition of asset
Replacement Cost	Cost to replace
Market Value	Estimate of price buyer is willing to pay
Equivalent present cost	Historic cost adjusted for inflation and worth in place
Productivity realised value	Net present value of benefit stream for remaining service life
Net Present Value	Cost of all activities completed for a time = 0 , allowing for discount rate
Sources of initial construction costs	Material, labour and traffic cost
Rehabilitation definition and cost sources	Major interventions to restore. Labour, materials and traffic control
Maintenance definition and cost sources	Activities to slow deterioration - Labour, materials and traffic delay costs
Typical construction cost percentages	Initial construction - 70 - 90% Rehabilitation - 10 - 25% Maintenance - Almost no effect Salvage/Terminal Value - Very little +ve effect
Three typical user costs for roads	- Vehicle operating costs - User delay costs - Crash costs
Ways to minimize user delay costs? User delay costs can be very significant ie 670k in 24hour work zone opposed to 80k in 12 hour zone.	- Adding capacity - Perform rehabilitation during off peak hours - Use longer lasting materials - Preventive maintenance - Using materials with faster construction sequences
Quality	Perception of the degree to which the product or service meets the customers expectations
3 Components of quality management	- Quality Control - Quality Assurance - Quality Improvement
Quality Control	Observation techniques and activities used to fill requirements for quality. e.g. Checking drawings, checking calculations, reviews
Quality Assurance	A set of activities to ensure that products satisfy customer requirements. e.g. External quality audits, internal checks on anything out of the ordinary
Quality improvement	Product improvement, process improvement and people based improvement. e.g. set up a quality management system, improve supply chain (LEAN), involving workers (to improve motivation)
Past mindsets on quality	- Increased quality will increase cost - Quality problems lead to blame, faulty justification and excuses - Quality is internally focused - Quality occurs at project execution
Present mindsets on quality	- Improved quality saves money and increases business - Quality problems lead to cooperative solutions - Quality is customer focused - Quality occurs at project initiation and must be planned for within project
