Foreword Project Director E ngā hau e wha, mai i Tāmaki Makaurau ki to ao whanui. He mihi manahau ki a koutou katoa. Topuni ki te Raki, Rakitu ki te Rāwhiti, Puketutu ki te Tonga, Oaia ki te Uru. Tāmaki herehere o ngā waka e! Tihei mauri ora ki te whai ao, ki te ao mārama. At the time of the last annual review, we had received the good news of the ISCA Leading rating award for the Albert Street works being delivered by Connectus. I was anticipating the results of the Downer Soletanche Bachy’s sustainability rating for the Britomart works. The wait was worth it. We achieved a Leading rating, matching the one we had achieved earlier. These are the only two Leading ratings awarded in New Zealand by the Infrastructure Sustainability Council of Australia (ISCA) and are higher than the Excellent rating we had targeted. The ratings are due to the acceptance and support of sustainability as a valid choice by the project team and our contractors Downer Soletanche Bachy and Connectus. It is the attitude and approach of people that makes the difference and the result saves money and resources now and for the future. Sustainability is a cornerstone of thinking in the City Rail Link (CRL) team where we aim to build New Zealand’s largest transport infrastructure project without using unnecessary resources or creating unnecessary waste. Once built, the CRL will give people more sustainable transport choices and we want to make sure we are sustainable in the process of delivering it. With an estimated 1,600 jobs on offer in the project at peak construction, we also want to contribute to social sustainability across Auckland, targeting employment for Māori, Pasifika and youth along with others marginalised in the workforce. To be successful, companies wanting to win contracts for construction will need to demonstrate how they are going to help us achieve our social outcomes strategy. There is no New Zealand sustainability standard for infrastructure, so we have embraced and enhanced the ISCA framework, working with Mana Whenua to make it more appropriate for the New Zealand context. We now also have our own project-specific technical manual. This document looks at the last year of our sustainability focus. We share it to detail our achievements and to inspire others to take up the sustainability challenge so that we all benefit.

will live in Auckland It is Auckland’s top transport priority and is essential to delivering the city’s strategic growth plans. CRL is also New Zealand’s largest and most complex transport infrastructure project. The project is fully funded by joint sponsors Auckland Council and the New Zealand Government, represented by City Rail Link Limited, which is charged with managing the delivery of the project for Auckland. Rail patronage has just reached a milestone of 20 million passenger trips annually, ahead of all predictions, with a steady year-after-year growth rate of almost 20%. The existing rail network comes to an end at the downtown Britomart Station, limiting passenger capacity in a city struggling to keep up with a rapidly expanding population and increasing traffic. The CRL will connect Britomart with two new underground stations (provisionally named Aotea and Karangahape) and a redeveloped Mt Eden Station where it will join the western line to create a two-way rail system that will also allow new services. Coupled with other transport investment in Auckland, CRL is essential to keep the city moving and its economy healthy.

Building a 3.4km underground rail link through the city centre is not without challenges, including the potential to consume significant resources and create substantial waste and carbon emissions if measures are not in place. Hundreds of workers are travelling to the city centre six days a week for the construction, and numerous businesses adjacent to works are being asked to accommodate access, traffic and parking changes. In addition, the CRL is happening under the watch of thousands of people working, living and visiting the city centre. New Zealand ratified the Paris Agreement on climate change on 4 October 2016 and the Agreement came into force a month later. Under the Agreement, New Zealand has committed to reducing emissions 30% below 2005 levels by 2030. The Climate Change Issues Minister described this target as ambitious, noting that “we’re not going to meet it unless we make changes”.1
In Auckland, transport is responsible for about 40% of greenhouse gas emissions, the majority from road transport. Maximising rail use will help reduce that figure as every trip not taken by car reduces the associated emissions by 89%. CRL will double the peak capacity of the rail network through Britomart and add 50% across the network. It will significantly reduce travel times, giving more vehicle commuters the choice of travelling by train – reducing our city’s footprint and helping New Zealand meet its international commitments on climate change. As Auckland prepares for a sustainable future, the CRL offers major benefits for all. This report details our progress on CRL’s sustainability journey in the 12 months to the end of July 2017.

Approach FOR CRL, SOCIAL AND ENVIRONMENTAL SUSTAINABILITY UNDERPINS THE ENTIRE PROJECT FROM CONCEPTION, DESIGN AND PLANNING THROUGH TO CONSTRUCTION. It is the only public transport project in New Zealand to measure carbon emissions associated with its construction and operation. Materials, energy and water use data will be gathered during construction and the goal is zero waste to landfill. CRL also has a focus on skills legacy, apprenticeships and new jobs for the unemployed as well as providing opportunities for small and medium-sized businesses with social outcome goals. It works hand in hand with eight Mana Whenua to reflect cultural values.

While the largest transport infrastructure project in New Zealand gets built, the CRL contractors have the opportunity to effect positive change in the lives of Aucklanders. CRL is asking contractors to consider opportunities for people identified in its strategy who are facing employment challenges. Affirmative life changes for individuals also improve the lives of their whanau and the wider community. Potential contractors are aware that social outcomes are expected. Social innovation is being promoted and CRL’s contractor requirements will encourage more participation and support of Māori and Pasifika enterprises in the supply chain. Discussions indicate that small Māori and Pasifika construction businesses are more likely to hire Māori and Pasifika people. For CRL this is a win/win situation. CRL is forming, developing and strengthening relationships with Mana Whenua, government agencies, community groups and education providers to address the current skills shortage and ensure that its future workforce is ready to go when jobs become available.
He waka eke noa, we are all in this together.
A CRL SOCIAL OUTCOMES STRATEGY HAS BEEN DEVELOPED WITH A VISION OF CONNECTING PEOPLE TO REAL OPPORTUNITIES THROUGH EMPLOYMENT, TRAINING AND SOCIAL INNOVATION. Employment for people experiencing disadvantage that provides: • Individual career development plans • Apprenticeships or equivalent pathways • Upskilling and reskilling that equips people for the present and future • Pastoral care.
Training that will: • Build confidence and competence • Provide relevant work-ready skills • Significantly improve chances of gaining quality employment in the construction, infrastructure and rail industries.
Social innovation by: • Providing supply chain opportunities for Māori and Pasifika small and mediumsized enterprises, other social enterprises and socially innovative businesses.

Infrastructure Sustainability (IS) Rating Framework CRL HAS ADOPTED AND ADAPTED THE INFRASTRUCTURE SUSTAINABILITY COUNCIL OF AUSTRALIA’S (ISCA) RATING FRAMEWORK AS A BASIS TO EVALUATE AND IMPROVE SUSTAINABILITY PERFORMANCE. The IS framework is a comprehensive rating and certification tool for evaluating sustainability across project design, construction and operation. The CRL project will need to meet criteria across the framework’s six themes:
MANAGEMENT AND GOVERNANCE
ECOLOGY
• Management Systems • Procurement and Purchasing • Climate Change Adaptation
USING RESOURCES
PEOPLE AND PLACE • Community Health, Well-being and Safety • Heritage
• Energy and Carbon
• Stakeholder Participation
• Wai (water)
• Urban and Landscape Design

CRL is a pilot project for the use of the IS rating framework in NZ and is targeting an ‘Excellent’ rating over the entire project. The IS rating tool focuses the project to: • Model and measure resource consumption • Identify and implement feasible opportunities to reduce consumption • Achieve significant reductions in resource use across the infrastructure lifecycle.
MAHI RAUORA ARATOHU CRL has worked with Mana Whenua to identify opportunities to respond to New Zealand’s cultural context within this framework, ensuring the sustainability criteria are compatible with te Ao Māori. This work, embedding cultural values across the IS framework, has led to the creation of a custom-made CRL Technical Manual, titled Mahi Rauora Aratohu. Mahi rauora translates directly to ‘work on the health of all things’ and aratohu translates as ‘pathway marker’ but can be interpreted as guidance, meaning this is 'the guidance for our work on the health of all things'. This technical guidance will be used for the remaining contracts. See more on our work with Mana Whenua on pages 32-35.
PROGRESS TO DATE ‘Leading’ rating for Contract 1 – Britomart Works The CRL has been awarded a ‘Leading’ Infrastructure Sustainability (IS) Design rating for Contract 1 – Britomart works, by ISCA. ‘Leading’ is the highest possible rating achievement within the IS scheme and this award follows on from the ‘Leading’ rating achieved by Contract 2 – Albert St works. Key sustainability initiatives planned for the Britomart works include: • Water-efficient fittings specified for the refurbished Britomart Station, which are projected to reduce water usage by more than 50%, with associated reductions in utility bills • The protection and enhancement of the Category 1 heritage-listed station building • Smart controls on escalators and other equipment to be installed in the station to reduce electricty use • Collaborating with Mana Whenua to embed cultural values across the IS framework; a first globally • Replacing diesel generators with grid electricity during construction. Find out more about the impact of these initiatives and others on the following pages.

Management and Governance SUSTAINABILITY IS A CORE PART OF CRL MANAGEMENT SYSTEMS TO ENSURE THAT SUSTAINABLE OUTCOMES ARE INTEGRAL TO DELIVERING THE PROJECT. Having a commitment to sustainability embedded in the management team thinking drives and normalises the approach across the project. For a project of this magnitude, it’s important to have sustainability management systems in place to set out processes and monitor performance and outcomes throughout project delivery. These outcomes can then be reported back and any lessons learnt along the way shared. Decisions are made, knowledge shared and reporting undertaken on an ongoing basis – not just at the end of any stage. In such a complex project with numerous partnerships, CRL needs to ensure its contractors are fully involved, committed to the vision and have the management tools in place to ensure targets are met. Every month, construction teams track energy, materials and water use and report on waste generated and what diversion paths are being found. In this year’s Annual Review, CRL shares its progress; you can see how the contractors are tracking on site in the Using Resources and Waste sections. Every quarter, overall reporting against the targets occurs at the management level. Regular reporting enables CRL to celebrate success and identify any areas of concern so the team can direct efforts to improve those outcomes. As New Zealand’s biggest transport construction project, CRL is looking to be an exemplar for the future.

Using Resources: Energy, Water and Materials DURING THE DESIGN PHASE, THE TEAM SOUGHT TO OPTIMISE RESOURCE USE FOR THE LIFETIME OF THE CRL. To measure success, total energy, water and materials use was estimated based on the early design (“base case”) and then the final “detailed design” was compared against it to quantify improvements introduced during the design phase. The team was successful in achieving projected reductions for both construction and operation, and these projected savings were reported in last year’s annual report. Since then, construction is well underway and the team has been tracking resource use on both construction contracts to see how well they are tracking against projections. The following pages show their progress.
ENERGY During design, the team was able to reduce the projected construction energy greenhouse gas (GHG) emissions by over 29% and projected operational emissions by more than 25%. This equates to a total saving equivalent to the GHG emissions associated with almost 18,000 economy flights between Auckland and London.2 The challenge for the construction teams is to stay within these carbon budgets and improve on them if possible. Energy is used during construction for everything from boring piles and transporting excavated spoil to heating water for workers’ tea and coffee. The main reason to reduce energy use is to reduce its associated GHG emissions, measured in tonnes of carbon dioxide equivalent (tCO2e).
TRACKING PROGRESS The two graphs opposite show emissions associated with energy use for both contracts is tracking well below both the base case and detailed design projections. Some of the apparent savings that have been achieved in the last quarter of the reporting period may be due to changes in the staging of the works since the original projections were done, but the results are encouraging. Both contractors are about to enter more energy-intensive phases, with DSBJV about to start piling and excavating under the CPO building and Connectus beginning the bulk excavation of the reinforced trench in Albert Street. Continuing to carefully manage energy use will be key over the next year. 2

Using Resources –
Energy, Water and Materials CONTINUED GRID ELECTRICITY One of the key initiatives for reducing the emissions associated with energy use on the project is to use electricity supplied from the national grid, rather than from diesel generators. New Zealand’s electricity generation is mostly from renewable resources, so using energy from the grid reduces emissions by about 85%. To take advantage of this, the project has installed three transformers for site electricity.
The first of these transformers powered the tunnel boring machine “Valerie” and has saved over 89,000 litres of diesel and avoided the release of 201 tCO2e of GHG emissions.

ENERGY EFFICIENCY AND CONSERVATION AUTHORITY (EECA) PARTNERSHIP Not all activities can use grid electricity (yet!), so CRL has partnered with the Energy Efficiency and Conservation Authority to implement a driver training and truck monitoring programme for the haulage of the 200,000 tonnes of spoil coming out of the Albert Street trench.
uc kd r iv e
The initial driver training course has been completed and shows potential for achieving valuable savings on diesel and associated emissions and cost. One of the drivers, who had nearly 40 years’ experience and believed his driving to be very efficient, achieved an 8.2% reduction in fuel use over a 40km course.

Energy, Water and Materials CONTINUED WATER / WAI Saving water is also a priority for CRL. As the design was refined from the base case reference design to the final detailed design, the team sought to reduce the amount of water that would be needed during operation of the CRL (discussed in last year’s report) as well as during its construction. To do this, projections of water use during construction were built up using information ranging from how many workers are expected to be on site, to how many trucks will need washing before driving onto Auckland’s roads. Initiatives such as reducing water for wheel washing by loading trucks with long reach excavators, (rather than them driving into the muddy Albert Street trench), and recycling the water used in the CPO piling works, resulted in significant projected reductions for both contracts.
WITH CONSTRUCTION UNDERWAY, WATER USE IS BEING MONITORED AND MAJOR WATER USES ARE BEING TRACKED BY SMART METERS THAT PROVIDE REAL-TIME INFORMATION, HELPING TO DETECT UNEXPECTED USE.

Water use on Contract 2 has been greater than projected at this stage due to very high use between December and March, when additional water was needed to cool the cutting head of the tunnel boring machine used for the stormwater pipe replacement. However, if the C2 construction team continues the low water use of the last few months, valuable reductions compared to the base case can still be achieved.

of greenhouse gas emissions
Constructing a large piece of infrastructure such as the CRL requires significant quantities of materials in particular concrete and steel - the production of which consumes valuable resources and produces greenhouse gases. During the detailed design phase, the CRL design team sought to minimise this “embodied carbon”, and was able to reduce it by 1,800 tonnes of carbon dioxide equivalent (tCO2e): just over 5% of the total.
This saving is equivalent to the embodied carbon of

During the construction phase, the team has continued to look for ways to reduce the impact of its material use.
*Based on BRANZ research on a 200m2 house
FLY-ASH An approach identified during design to reduce the GHG emissions associated with concrete was to specify fly-ash, a waste product from coal-fired power stations, as a partial cement replacement. With construction underway, data collected to date by contractor Connectus shows that specifying fly-ash for the 362 20-metre piles in Albert Street has reduced their GHG footprint by over 8%, saving approximately 122 tCO2e of GHG emissions.

50MM REINFORCING BAR Changing the piling methodology underneath Britomart Station from contiguous piles to diaphragm walls contributed to an initial reduction in steel use during the design phase and also reduced the time and cost of the station underpinning. However, due to the depth of the rock under the station (around 20m), using 40mm reinforcing bar (the largest size available in New Zealand) would have resulted in reinforcing bar “congestion”, preventing the concrete properly flowing around the bars to form the diaphragm wall. Fewer, but larger, bars were therefore required. However, these had not been made previously in New Zealand. Contractor DSBJV worked with local manufacturer Pacific Steel in Otahuhu, which uses steel from the Glenbrook steel mill 40km east of Auckland, to fabricate New Zealand’s first 50mm reinforcing bar. Besides improving constructability, using this larger diameter steel reduced the total weight of steel required by about 82 tonnes, lowering associated greenhouse gas emissions by just over 100 tCO2e. It also reduced the transport emissions and costs associated with sourcing it offshore. St e e l c

Emissions, Pollution and Waste ENVIRONMENTAL MONITORING To protect the built environment, CRL has put in place a state-of-the-art monitoring system. A component of this is the Cyclops 3D geodetic system that continuously checks for any movement of buildings adjacent to the works. The system works using hundreds of small monitoring prisms and several "total stations� that use lasers to take measurements with extreme accuracy. If any unusual movement is detected, the system alerts the team to take action to prevent excessive movement or damage to neighbouring or affected buildings.
p T h e C ycl o
< Kaikoura Earthquake
In addition to the slower movements detected by the Cyclops system, continuous vibration monitoring is also in place to ensure that works do not exceed thresholds set by Auckland Council. The system was sensitive enough to detect the Kaikoura earthquake, almost 670km away.

WATER QUALITY / WAI ORA Digging tunnels is inevitably a mucky business, particularly when it rains. To protect the harbour and surrounding streets from water contaminated by the excavation works, the construction team implements measures such as protecting stormwater drains using large sediment-catching â&#x20AC;&#x153;socksâ&#x20AC;? and using settlement control systems that remove contaminants from the water. Looking much like a skip bin attached to water tanks, these settlement systems contain a series of inclined plates forming a large area onto which suspended solids settle, changing muddy water to clear water. Regular testing ensures that the water is free of sediment and contaminants and has a neutral pH, before it is released into the stormwater system and ultimately the harbour.
WASTE Waste reduction starts with efficient design: avoiding the use of materials that will later need to be discarded, and reducing the amount of materials that are needed overall. Construction will always create some waste, so the aspirational goal of the CRL project is to divert all construction waste from landfill. To try to reach that goal, CRL construction teams have been challenged to use the waste hierarchy to avoid, reduce, reuse, recycle and recover as much waste as practicable. This challenge has resulted in some great innovations.

Emissions, Pollution and Waste CONTINUED LIGHTWEIGHT FILL As part of the work to allow the train tunnels to be extended underneath the CPO, deep trenches needed to be excavated by a 100-tonne hydrofraise rig in order to install the reinforced concrete foundation walls that will underpin the building.
This method is faster, cheaper (by about $450,000) and because the polystyrene blocks will be undamaged, the supplier has agreed to take them back for reuse once the work is complete.

In several areas this required the floor level to be built up to match that of its surrounds. The plan was to use compacted crushed concrete backfill and 62 mini piles to support the concrete platform from which the hydrofraise can work. The revised design, however, uses polystyrene blocks, pumice sand and only 30 mini piles to support the platform. sty

e
The approach therefore reduces the amount of new material needed (through a reduction in the number of piles needed) and diesel used (for drilling piles and delivering and compacting the backfill) and the polystyrene will remain in good condition so that it can be re-used, for instance as underfloor insulation, avoiding any waste going to landfill.

TRACKING PROGRESS As well as one-off initiatives to eliminate waste going to landfill, the CRL contractors also have systems in place to deal with the day-to-day waste that is produced and track where it goes. This ranges from biodegradable office waste collected by We Compost for composting, to demolished concrete being sent to Green Vision for crushing and re-use and general construction waste being sent to Green Gorilla for sorting and recycling. As of July 2017, 40,801 tonnes of waste have been generated, of which 29,956 has been diverted from landfill. Although the aspirational goal of all waste being diverted from landfill has not been achieved, the charts below show that significant quantities have been diverted.

the tunnel boring machine after it had completed the two-metre diameter stormwater pipe. Large reinforced concrete ring segments were used to form the shaft and extra ones ordered for contingencies were not needed. Rather than being sent off as waste, these were then used to divert the Orakei main sewer while the original line was being strengthened. Besides diverting the left-over ring segments from waste, this approach also avoided the use of formwork, reinforcing steel and concrete that would have otherwise have been needed to construct the diversion.

People and Place CLAIMING BACK LOWER QUEEN STREET
Commuters, residents and visitors enjoy time out on the luscious green grass with deck chairs, picnic tables, live entertainment and local business market stalls
Lower Queen Street, where the city meets the sea, is the gateway to Auckland’s city centre, attracting 50,000 commuters and visitors a day. In 2016, vehicle access was removed and the street was transformed into a bright and bustling hub of social activity. Partnering with Activate Auckland, the CRL team created a sense of manaakitanga (hospitality) with the installation of astroturf and surface paint, making a huge difference to the street's look and feel. It soon became a meeting point and a social space with buskers, art installations, tour promoters, interactive community events and the city centre iSite, bringing new life to the area.
"THE PACIFIC JOURNEY" ON LOWER QUEEN STREET In February 2017 the Chief Post Office on Lower Queen Street was closed in preparation for the CRL construction. About 45m of hoardings were erected around the building, providing a great opportunity for creative collaboration. A partnership between CRL, ATEED and Activate Auckland was formed to commission the artistic duo of Charles and Janine Williams. Over three weeks, they created a mural in the public eye to celebrate the 25th anniversary of the Pasifika Festival.

The Cheap Eats campaign evolved from recognising that the Albert Street area is a melting pot of different types of cuisine from Asian fusion delights and mouth-watering burgers to world-class coffee and delicious muffins. To draw attention to the huge range of meals available for under $15, postcards, maps and a Facebook campaign were designed to encourage people to explore Albert Street's wide variety of dining spots. The campaign shows that construction, both private and public, shouldn’t stop people enjoying what’s on their doorstep.
NEW CRL HOARDINGS ON ALBERT STREET As CRL works progress along Albert Street, the project hoardings were moved progressively from the footpath to the centre of the road. With hundreds of metres of hoarding required, the project team looked for a design that would provide a restful element amid the buzz of construction. Working with members of the community, CRL has opted for native trees and birds to create a bright and vibrant front garden for the street. The design provides a softening touch to the construction hoardings that will be a part of Albert Street for the next 18 months. The hoardings also provide wayfinding and remind people that all local businesses are open as usual during the construction period.

During the early reclamation, household rubbish and building debris was thrown in (along with the fill from the 1859 demolition of nearby Smales Point). This household rubbish is the likely source of the hand-made ginger beer bottle uncovered during the excavation. Because the maker’s mark – Fowler – was stamped on the bottle, the project archaeologist was able to trace the artefact back to Enoch Fowler, who arrived in Sydney in 1836 as a free settler from Tyrone, Ireland, and made ginger beer bottles and kitchenware. It’s perhaps not surprising that a ginger beer bottle from Sydney might turn up in Auckland, given that New Zealand was (briefly) officially part of New South Wales. The bottle provides a tangible link between Auckland’s colonial past, its early infrastructure development and work to help keep the city thriving more than 150 years later.

For the strategy, Berenize was looking for an image that represented her Māori world view and her current work environment. She enlisted the help of CRL graphic designer Geoff Fitzpatrick to give her ideas some substance. Geoff said that he was immediately captivated by the idea and used his passion for design to take a picture that existed only in someone’s imagination and translate it into something tangible. He also worked with artist Maaka Potini of Ngāti Tamaoho to include his original design for the taurapa (stern of the waka).

The tangata (person) below represents the captains. The two manaia at the bottom of the taurapa are the kaitiaki (guardians) that helped to protect the people and the waka. Maaka connects these attributes to those who schedule, drive and crew the trains. “For me the image represents the past, present and future. Where Britomart stands now used to be water and the image depicts the change from a traditional waka to a modern equivalent a train,” said Berenize.

The Mana Whenua forum said the taurapa acknowledged the great fleet that brought Māori to New Zealand and the manaia (stylised figure) at the top is a tribute to all of the tōhunga (specialists in esoteric knowledge) that were aboard.

C1 IS Design Rating In 2017, the CRL was awarded a “Leading” Infrastructure Sustainability (IS) Design rating by the Infrastructure Sustainability Council of Australia (ISCA), the highest possible achievement in the IS scheme. This followed on from one previously awarded for the C2 contract: the only two awarded in New Zealand. Following on from the work with Mana Whenua last year to embed cultural values across the IS framework, the project now has a custom-made CRL Technical Manual, Mahi Rauora Aratohu. This translates to 'guidance on the work for the health of all things' and will be used for the remaining contracts.

Principal Technical Advisors A vibrant and sustainable future is not an impossible dream. By embracing change and disruption Aurecon creates liveable design solutions that deliver enduring intergenerational equity of resources and infrastructure. Embedding sustainability into every aspect of our operation and project delivery is fundamental to driving change. Aurecon’s philosophy centres on building an innovative and diverse culture around sustainable economic, social and environmental impacts. “I am a Kiwi who spent 17 years overseas working on major rail projects. I am passionate about sustainable transport and hopefully, my contribution to this city-shaping project will help many Aucklanders to reduce their dependency on cars to get around the city.” - Grant Daniel, Technical Director, Transport
For Mott MacDonald, sustainability aligns with the goals of achieving more for less and more with less. We show that cost savings can be achieved by pursuing sustainable solutions - often when conventional performance and cost drivers are exhausted. On Contract 1, we’ve assisted with a Britomart Plaza roof design by optimising the transparencies of the roof material to reduce the risk of overheating whilst maintaining good levels of daylighting. We’ve helped to optimise the arrangement of the plant and equipment rooms to minimise the use of building materials. Mott MacDonald seek opportunities to look at old problems with new eyes and consider how sustainability can strengthen the solutions to new challenges.
Sustainable design is in the DNA of Jasmax, our people and our work. The process of learning, evolution and development is exemplified in the redevelopment of Britomart Station for the CRL. Britomart’s development achieves sustainable excellence on many levels. Jasmax (with Mario Madayag) was involved in its development almost 15 years ago, with the adaptive reuse of the historic Chief Post Office. Today, as we’ve continued the Britomart journey (in association with Grimshaw Architects), we’ve realised how resilient that design was. It’s been able to adapt and extend, becoming a vital part of the CRL. Over 100 fixtures, fittings, and material items from Britomart have been repurposed into the new CRL station. From tapware to stonework, the CRL and Jasmax team have worked to ensure sustainable design thinking has been applied across all aspects.
