Aviva Stadium

Dublin, Ireland

º£½ÇÊÓƵ played a key role in enabling the development of a landmark new stadium for Dublin on an historic, but challenging site.

A striking, transparent form sitting on the famous Lansdowne Road site, Aviva Stadium offers Dublin both a visually spectacular venue and the first truly ‘responsive’ stadium building of its type in the world; its form and materials being shaped and moulded to suit the specific constraints of this special and historic site and its surroundings.

Challenge

With a 50,000-seat capacity, this cutting-edge building is home for both the Irish Rugby Football Union and the Football Association of Ireland, accommodating both sports at the very highest international level.

Built on the extremely constrained existing site in a residential area, wrapped around the local DART (Dublin Area Rapid Transit) railway line, the challenge for our team was to deliver a building that was able to house thousands of passionate fans, in a venue of sufficient size to deliver top-flight sport, entertainment, safety and comfort, while keeping the famous Lansdowne Road atmosphere at the heart of its design.

The engineering challenges for the stadium itself were led by the ever-varying geometry that enabled the design to work around the various constraints, with all sections being unique and parametrically developed.

Solution

Numerous bowl-geometries were studied and modelled to arrive at the right balance between distribution of seats within seating-tiers, quality of viewing, and facilities behind each tier. The solution to realising this landmark venue in the challenging site lay in the building’s unique form. The design team moulded the envelope to respond simultaneously to the close proximity of adjacent roads and properties, tight spectator access and egress issues, the accommodation of the adjacent railway line through the edge of the building, as well as ensuring maximum fan experience.

The engineering design responses include an innovative steel roof with a unique ‘horseshoe’ truss and dramatic frame geometry with 4m cantilevering floorplates and inclined, curving concrete blades. The resulting enclosure sweeps its way around the building, navigating each of these constraints to rise in the east and west, dropping slightly to the south adjacent to Lansdowne Road itself, but then dropping dramatically to the north.

Our engineers designed an undulating, complex two-part roof, spanning more than the three higher tiers and connecting to an independent shell structure over the lower north stand. In effect, the roof spans the whole perimeter of the building wrapping back on itself through 180 degrees.

Aviva’s striking facade is constructed using 19,000m² of polycarbonate panels to achieve the architect’s vision for a stadium that reflects its waterside surroundings and showcases the original and unique form. Highly distinctive and innovative, the º£½ÇÊÓƵ-designed roof offers an uncompromising experience for spectators – dipping down to the southern sky, the transparent structure allows sunlight to flood the high-performance sports turf to create the ultimate playing surface. Lying below the roof, the stadium’s seating stands are positioned to ensure optimal sightlines for spectators.

We led on the use of bespoke 3D digital design techniques, which were cutting edge at the time of development, which enabled close collaboration across disciplines and with design team partners, led by the architect Populous.

Our experts also led the wind engineering for the project including looking at safety and comfort within and without the stadium as well as the structural and cladding loadings.

To the west and south-west of the site, the stadium meets the major urban commuter route of the DART railway line. The west stand of the old stadium was built over the rail line. Previously many spectators needed to cross the railway via a level crossing. The new design integrates a podium to provide safe access for spectators arriving by train.

Significant site works engineered by º£½ÇÊÓƵ as part of this improvement included the demolition of the former stadium west stand over the DART and the creation of a new rail corridor integrated within the overall development next to the stadium.

We designed the sequencing of the demolition and proposed the schedule for the programme of works to ensure minimum disruption to the busy railway line, liaising closely with all parties, including the Irish Rail network operator Iarnród Éireann, service providers and other key stakeholders. This involved carefully managed intense bursts of activity, with highly programmed rail possessions over Easter and Bank Holiday closures.

Since 2020, º£½ÇÊÓƵ has continued to support Aviva Stadium in a trusted advisor role, providing strategic asset consultancy to safeguard the long-term performance of this world-class venue. Our additional scope began with a fundamental challenge: after a decade of sporting events and ongoing modifications to the stadium, the client needed a clear understanding of its current condition and future investment needs. Over time, incremental changes and adaptations had led to gaps in documentation and knowledge, making it difficult to form a complete picture from existing records. 

We responded by developing a comprehensive asset register and undertaking a full lifecycle analysis, surveying every element from structural steelwork to finishes and services. 

This process delivered more than a database. It provided the client with a robust, evidence-based financial model that aligns technical realities with operational priorities. By categorising assets according to condition, statutory requirements and business criticality, we created a forward investment plan that not only addresses immediate compliance obligations, such as preparations for UEFA EURO 2028, but also supports long-term resilience and net zero ambitions.

Our analysis highlighted long-term investment needs in excess of €100 million over the next 25 years. Through scenario modelling and strategic smoothing, we helped the client shape a manageable investment profile, enabling informed decisions on when to refurbish, upgrade or replace key systems. 

Value

A stadium must have a sense of place, identity and uniqueness. The design team understood the value of locating the new stadium within the unusual site and wanted the design to be site-specific.

Our multidisciplinary team of experts was able to take the constrained existing city centre site, previously home to an overwhelmed and underperforming building, and through carefully considered design, developed a strategy to redevelop it and deliver a modern, state-of-the-art venue that could remain on its historic site. By using our engineering skills and strong collaboration with our architectural colleagues, we have created a building that few thought possible.

The bowl shape and roof and facade envelope were developed as one, in a seamless manner – thereby creating the landmark form that immediately became uniquely associated with Aviva Stadium on the Dublin skyline.

The value of our more recent asset consultancy work extends beyond cost planning. By integrating sustainability measures, such as opportunities for photovoltaic installation and electrification of plant, and by considering future fan expectations around connectivity and experience, we have positioned the stadium to remain competitive for decades to come.  

Acting as lead coordinator among stakeholders, we brought together architects, financial advisors and technical specialists to ensure a holistic approach. This strategic insight has underpinned a compelling business case for future funding and has strengthened the stadium’s ability to plan with confidence. It is a clear example of how º£½ÇÊÓƵ’s expertise in asset management helps clients unlock long-term value from their assets. 

º£½ÇÊÓƵ’s lifecycle analysis delivered exceptional technical insight and strategic clarity. Their expert assessment of our infrastructure and engineering systems formed the backbone of our Lifecycle Plan — clearly articulating the timing, scale, and criticality of future investment needs. This work has been instrumental in helping us engage the Government and other key stakeholders with a robust, data-driven case for reinvestment to ensure the stadium’s long-term sustainability.
