Delivering CRL Sustainably • 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


Focus areas • 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


Carbon footprint

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


Infrastructure Sustainably • '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 Sustainability Council of Australia


Kaitiakitanga, Sustainability & CRL 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.


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


Infrastructure Sustainably Work undertaken: • Materiality assessment for the scope of each contract package • Reference design level footprints - for operations only • Principal’s evidence



Design Management Process • • • • • • •

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


Gateway Reviews • 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


Interfaces • 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


BIM • • • •

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


The Challenge • • • • • •

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
