5
Input Driven Contracts Typically –“Direct Labour” –“Plant Hire” –“Day Works” –“Maintenance by Administration” (MBA) Provide detailed methodology and payment is for individual inputs –Labour by hour –Plant by hour –Materials by quantity delivered
6
ASSET OWNER CONTRACTORCONSULTANT Output Driven Contracts Payment is by schedule of rates for each completed repair with a warranty period Some flexibility in methodology Separation of Service Delivery Components
7
Consultant may be: - in-house - joint venture partner - or sub-contracted to contractor - lead contractor ASSET OWNER CONSULTANT CONTRACTOR Outcome Driven Contracts Only desired outcomes specified Complete flexibility in methodology Payment by lump sum Typically one point of contact

Definitions Definitions efficiency - measured by a comparison of production with cost (as in energy, time, and money) –Doing things right effectiveness: ability to produce a decided, decisive, or desired effect –Doing the right thing efficacy: the power to produce an effect –Setting the right objectives

2 New Zealand Models
13
Contract Models for Road Network Management in New Zealand Conventional Performance Specified Contracts (“PSMC” & “PBC”) “Hybrid”
14
Separate Schedule of Rates Contracts for: –Asset/corridor management (Consultancy Roles) –Routine Pavement Maintenance –Corridor Management vegetation control signs –Resurfacing –Pavement Rehabilitation Consultant RCA Contractor 1 Conventional Model
15
Conventional Model - continued Increasingly the maintenance contracts in the “Conventional Model” are performance based e.g. –Grass cutting –Pot hole repair response times –White line marking –Spray seals –Pavements
16
Typical Roles R C A Audit Agree investment needs Manage funding Issues Approve asset management plan Consultant Develop network management strategies Draft asset management plans (Seals, Rehabs etc) Approve Routine Maintenance Program Audit Work Done Approve Claims Contractor Identify Routine Maintenance Work Prioritise & program Routine Maintenance Execute works Ensure work quality and satisfy liability requirements
17
Issues Client “control” –Focus can be directed to all elements of the asset e.g. Vegetation control –Adversarial management style? Information Symmetry
18
Contracts Can Create “Information Asymmetry” Physical Work Intervention Levels of Service Key Success Factors (Link) Key Success Factors (Network) Work Instructions Physical work Management Governance Conventional
19
All three parties need “Information Symmetry” Maintaining open lines of communication across the contract interfaces is essential Internationally fear of “asymmetry” is limiting the progression of outsourcing
20
Single Lump Sum Contract for all activities Includes all –All Routine maintenance –Pavement Rehabilitation –Surfacing –Minor Safety Improvements –Consultancy roles PBC also includes some capital improvements –Seal extensions & seal widening Contractor Consultant RCA Auditor 2 PBC & “PSMC” Models
21
Issues Maintenance Liability –Controlling the “consumption” of the asset during the term of the contract Require –A robust inventory of the asset –Clearly defined outcomes –An understanding of the performance of the asset. –Equitable risk sharing –Confidence in the industry! Place a strong emphasis on trust and long term relationships They are still in the early stages of development
22
Special “Risks” for Local Authorities Risk Profile - 100% of network? Rate payer interfaces Impact on Local Contracting Industry Changing levels of service Lowly trafficked roads –Levels of service –Cost of compliance
23
Physical Work Intervention Levels of Service Key Success Factors (Link) Key Success Factors (Network) Work Instructions PBC Contracts Can Also Create “Information Asymmetry” Physical work Management Governance PSMC
24
Check List for PSMC’s If you know What you have –What is it worth –What do you want it to do –What condition it is in –What you need to do to it –When you need to do it – You can expect to get a robust lump sum price for maintaining your network for an extended period
25
Client ConsultantContractor Auditor 3 Hybrid Model for Network Management Two Lump Sum Contracts –Physical works includes resurfacing Area wide treatments all routine maintenance winter maintenance (outside lump sum) –Consultancy Contract includes medium to long-term asset management Corridor management information management Safety auditing separate “auditor” role Client picks the Contractor /Consultant Team
26
Most significant differences From the Conventional model –Self auditing by contractor –Heavy reliance on partnering From PSMC –Hybrids do not require as robust definition of outcomes. e.g Residual pavement life is not as big an issue as there are underlying quantities of work –demands for data at tender stage are far less Note: Reprioritisation of the Lump Sum is allowed with agreement
27
Issues Less duplication = reduced price? Client selects the team More price certainty than conventional model Allows more client involvement/influence Note: this may allow a stronger ratepayer focus

4 Personal Thoughts
33
I Believe Cost Savings Are Principally About: The size of the network –Annual expenditure In WA varied from 315km to 4280km but expenditure was about the same The duration of the contract The management style –Creating a win/win environment A competitive market –Note: Conventional maintenance tenders were 20% less than our estimates last year
34
All 3 NZ models are capable of delivering the similar benefits if the playing field is level. However the PBC model provides: –an instrument for forcing advanced asset management into a network –a way around our established paradigms But in the end it is the people that really make the difference in each model
