Community

At OCC, we take pride in our strong ethos of giving back. We have built and maintained strong, meaningful relationships with local and national charities, as well as the communities we serve. We believe it is both a privilege and a responsibility to support those in need, reflecting our gratitude for the opportunities we’ve been given.

In 2024 alone, OCC Construction donated €28,000 to numerous charities and sponsored various sporting organizations, including all charities nominated by our employees.

Since OCC’s incorporation in 2010, approximately €241,000 has been donated to charitable causes. Each year, we invite our employees to share the charities that matter most to them, providing an opportunity to nominate a cause of their choice to share in a generous fund donated by OCC Construction.

Environmental Social Governance

OCC Construction’s Commitment to ESG
At OCC Construction, ESG principles shape how we operate. We work to reduce environmental impact, support our people and communities, and maintain transparent, responsible governance.

Environmental Responsibility
With ISO 14001 certification, we focus on sustainable construction—using energy-efficient methods, minimizing waste, prioritizing local materials, and delivering projects such as LEED and passive-house developments that align with global sustainability goals.

Social Responsibility
We create a safe, inclusive workplace and support employee well-being through healthcare benefits, an EAP, and development programs. We also give back through community involvement and charitable initiatives.

Governance Excellence
ISO 9001, ISO 14001, and ISO 45001 certifications guide our commitment to quality, ethics, safety, and accountability. Our sustainability goals align with global standards to deliver long-term value.

OCC integrates ESG across all operations, driving innovation and positive impact for our clients, communities, and the planet.
