Planned Outcomes

A safe reliable and attractive railway

  • 24 trains per hour in each direction ultimate track capacity
  • 18,000 passengers per hour in each direction as the ultimate

patronage capacity through two new stations and two modified stations

  • Future proofing oversite development opportunities at each

station

  • Sustainability IS project target rating 'excellent'
  • Operating in 2023/24

  • Decision making that considers social, environmental

and cultural impacts, risks and opportunities

  • Truly integrated design
  • Understanding and considering whole of life costs
  • Collaboration around interfaces

Delivering CRL Sustainably

slide-68
SLIDE 68
  • Reducing resource consumption - measuring CRL’s carbon footprint
  • energy, water, materials
  • Zero waste to landfill - aspirational goal
  • designing out waste
  • avoiding construction waste
  • Social outcomes
  • workforce development, employment, social enterprises
  • Mana Whenua outcomes - kaitiakitanga
  • Reporting - qualitative and quantitative

Focus areas

slide-69
SLIDE 69

Comparing three options for constructing 200m long, 7-9m deep platform trench

Carbon footprint

slide-70
SLIDE 70
  • 'Excellent' Design and As-built rating

for whole project

  • Each contract package will be

contributing their own rating

  • C1, C2, C3, C5, C7 and C9
  • (not C6 and C8)
  • New Zealand pilot - CRL version:
  • NZ criteria
  • incorporates Mana Whenua cultural

values

Infrastructure Sustainably

Infrastructure Sustainability Council of Australia

slide-71
SLIDE 71

Kaitiakitanga includes:

  • protecting, restoring, enhancing the mauri of te Ao Māori;
  • fulfilling spiritual, emotional and inherited responsibilities to

the environment;

  • maintaining mana over te taiao; and
  • ensuring the welfare of the people.

In Tamaki Makaurau it is Mana Whenua who are Kaitiaki. In meeting their sustainability commitments the CRL project is supporting kaitiakitanga and Mana Whenua as kaitiaki.

Kaitiakitanga, Sustainability & CRL

Social Outcomes for Auckland

  • There are eight local boards with higher than

average numbers of people Not in Employment Education or Training (NEET)

  • There is a significant skills shortage in

construction and infrastructure

  • Creating positive social value through the

delivery of CRL

slide-73

Process

  • Particular requirements
  • Planning conditions
  • Mandated design elements
  • Interface management and control
  • DOORS Database
  • Multi-discipline Gateway Reviews
  • Systems Assurance

Design Management

slide-77
SLIDE 77
  • Progressive information co-ordination and delivery
  • Intermediate gate in interactive pre-award period

  • On line real time demonstration of the co-ordinated information

delivery and compliance with requirements

Gateway Reviews

slide-78
SLIDE 78
  • Interface boundary mapping and ownership- DOORS
  • C3-C6, C3-C2, C3-C7, C3-C5, C3-C9
  • C7-C1, C7-C2, C7-C3, C7-C5, C7-C9
  • Interface control documents
  • Geographical co-ordination
  • Cross boundary co-ordination
  • Collaborative development - cross contract resolution
  • Collective responsibility

Interfaces

slide-79
SLIDE 79
  • Fully co-ordinated 3D model required
  • Single source of truth required throughout delivery
  • Cross contract co-ordination into one federated model generation
  • BIM 200 at start, BIM 400 on completion of the works

BIM

slide-80
SLIDE 80
  • Not to hurt anybody
  • Maintain design quality and cultural narratives
  • Improve delivery programme - working smarter
  • 20% cost reduction
  • Meeting all RMA designation conditions
  • Key specialist resources in place at start of contract and

maintained through delivery

  • Draft OPW’s in place prior to contract award and lodge within four

weeks of award

  • Exceed sustainability targets to ‘leading’ status
  • To leave behind a more skilled workforce
