Earlier this month, a team from our London office took part in the Built World Cup, a five-a-side football tournament with teams from across the built environment.
Organised by @ingmedia_ and @thedevelopersclub.uk, the event raised over £11,000 to help rebuild Ukraine. Well done to James Pavely, Zoe Ward, Chiara Bariviera, Balkaar Singh, Marialena Toliopoulou, Joel Frost, Anurag Sonar, Vishnukumar Rajasekar, Haakon Lim and William Morley for reaching the Quarter Finals.

Congratulations to our Group Marketing and Communications Manager, Ailish Hendry, on successfully passing her exams and becoming a Chartered Marketer with @cim_marketing. A fantastic milestone in her career, well done!

In an aim to protect the endangered Mindoro Warty Pig species, a new conservation campus was created in the Philippines for long-term animal care and staff wellbeing. The campus includes staff accommodation, a dedicated disinfection and food storage facility, as well as six large pig enclosures.
Continuing Eckersley O’Callaghan’s commitment to charitable work, our structures team designed the timber structure for the staff accommodation and disinfection facility as part of this pro bono initiative. Both buildings were designed in response to the climate, site conditions and construction in a remote area, whilst also ensuring durability and easy maintenance.
Built by @caukinstudio alongside local workers and volunteers, the buildings were constructed using local, sustainable and easily accessible materials, with a significant proportion of the timber being reclaimed and donated by the local government.

Last week, Nicola Sacco and Chiara Bariviera represented Eckersley O’Callaghan at FORMA’s Mass Timber Seminar, sharing their practical, experience-driven perspectives on designing and delivering timber at scale.
Presenting on ‘Mass Timber in Practice – Structural Insights’, Nicola and Chiara explored the structural application of engineered timber, discussing key properties such as structural capacity, architectural qualities and sustainability. They also addressed some of the challenges associated with mass timber, including fire performance and moisture control.
Using some of our projects to provide real-world examples, they referenced the Black & White Building, City of London Freemen’s School Swimming Pool and Vitsoe, to demonstrate the variety of possible applications and opportunities that timber offers.

Congratulations to Tim Lui, Wasim Illyas and James Pavely on successfully passing their chartership exams, a fantastic milestone in their careers. Well done!

On 7th May, Alessandro Baldini, Director, and Chiara Tosi, Associate, from our Milan office, will be at @zakwof in Rome.
Marking the first ZAK conference to take place in Rome, the heritage buildings of the 'Eternal City' highlight the importance of adaptive reuse in maintaining historic architecture. Ale will open the event with his presentation ‘Designing the Building Skin: Facade Engineering Between Retrofit and Contemporary Architecture’. With building retrofit being a key theme across projects in Rome, he will explore how facade engineering supports reuse-led design, and how targeted envelope upgrades can deliver performance, value and design quality.
If you're attending the conference, be sure to attend the session and say hello if you see Ale and Chiara around. Learn more about the session via the link in our bio.
Sydney Harbour Bridge Cycleway Ramp has been shortlisted for ‘International Bridge Project of the Year’ at the @new_civil_engineer Bridges Awards 2026.
Filling a major gap in Sydney’s cycling path infrastructure, the cycle ramp creates a continuous north-south route across the Harbour Bridge with links from North Sydney through into the CBD via Kent Street.
In an exclusive article with @dezeen, discover how our structural engineering and industrial design expertise helped realise this project alongside the wider project team. Read the article via the link in our bio.

Meet... Andrea Hellerman, Associate Director
Andrea joins Eckersley O’Callaghan to lead and strengthen our Forensic & Diagnostic Engineering service.
