Pedestrian Bridges - Western Line

Perspective of Normanby Road

• Western Line Metro and freight services maintained• Limited full blocks of line• Staged testing and commissioning • Civil, structural, trackwork, railway systems scope

Western Line

• 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

• 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

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

Carbon footprint

• '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

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

Journey so far

Contracts 1 & 2

Work undertaken:

• Materiality assessment for the scope of each contract package

• Reference design level footprints - for operations only

• Principal’s evidence

Infrastructure Sustainably

Process

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

Design Management

• Progressive information co-ordination and delivery- Intermediate gate in interactive pre-award period- Gates through detailed design- Final gate at completion of detail design

• On line real time demonstration of the co-ordinated information delivery and compliance with requirements

Gateway Reviews

• 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

• 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

• 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
