Sustainable Site Welfare Solutions with John Sisk & Son

Renowned for delivering high-quality projects ranging from intricate commercial buildings to expansive infrastructure projects, their dedication to excellence is renowned, along with a profound commitment to sustainability and environmental stewardship.


The diverse and often transient nature of John Sisk & Son’s projects presented a unique challenge: providing high-quality, functional, and sustainable workspaces for their on-site teams. The company sought a solution that would not only offer practical benefits but also align with their ambitious sustainability goals. They needed workspaces that were adaptable, eco-friendly, and reflective of their brand’s commitment to making a positive impact on the environment.

The Solution: Sustainability at the Core

“At Sisk, we’re dedicated to leading the way in sustainability, ensuring that our projects not only meet but exceed environmental standards. CabinTec’s innovative approach to eco-friendly cabins has been instrumental in helping us achieve our sustainability goals,” remarked Barry Murphy, Plant Operations Manager at John Sisk & Son.

CabinTec’s designs focused on energy efficiency, utilising sustainable materials, and minimising waste, thereby significantly reducing the environmental footprint of temporary construction site setups.

Tailored and Efficient

Working in close collaboration with John Sisk & Son, CabinTec developed customised cabins that were specifically engineered to meet the unique demands of each project site. Rapid deployment and flexibility were key, ensuring that these eco-friendly solutions were delivered swiftly and could be adapted or relocated as project needs evolved.

Promoting Environmental Welfare

CabinTec’s cabins were not only designed with sustainability in mind but also aimed to enhance the overall site welfare. By providing a comfortable, safe, and energy-efficient environment, these cabins supported John Sisk & Son’s workforce, fostering well-being and productivity on site.

A Partnership for the Future
