At the heart of the Caledonian business is a commitment to delivering high-quality projects in a safe and sustainable manner.


The safety of our people and the operation of a safe working environment (both offsite and onsite) is our overriding priority. Through thorough training and continual reinforcement, we actively promote a positive awareness of health and safety and propagate best-practice within our culture.


Our offsite construction process is a highly sustainable method of building with completed projects inherently achieving high standards of energy efficiency. Typically, Caledonian buildings display excellent air tightness dynamics and are designed and built to meet enhanced insulation, acoustic and thermal properties in compliance with the latest building regulations and client requirements.

Our offsite building projects also minimise traffic movements, as modules are delivered to site with a high level of fit-out negating the need for site deliveries and high levels of onsite labour.

Committed to maintaining our ISO 14001 certification, our environment management systems are routinely audited by independent external bodies in conjunction with our internal team.

As many of the projects we deliver are long term investments for our clients, we understand that operating costs are as important as the capital cost. Working with our clients from early engagement, we constantly deliver projects that achieve FM cost targets and provide buildings that benefit from low running and maintenance costs.


Caledonian is committed to reducing waste as part of the design process and to recycling up to 100% of waste from our factories and construction sites. Currently 96% of factory waste is diverted from landfill by recycling through a MRF (Material Recycling Facility), re-using or converting to energy through a RDF (Refuse Derived Fuels) plant.


Operating in a factory environment we are able to meticulously monitor processes and embed Quality Assurance at every stage of build. We have a zero tolerance policy on defects throughout our factories.

Quality inspections and final sign-off are completed as the modules are prepared for transport and thorough inspections are carried out upon arrival on site.

We are committed to producing quality buildings that maintain the highest standards throughout their lifespan.
