For almost 50 years, Mercury has been delivering complex engineering projects that focus on making a positive impact and improving life in the built environment. We believe in doing things better, faster, smarter, and more sustainably. We have pledged to reduce our scope 1 & 2 greenhouse gas emission intensity by 50% by 2030. In addition to our commitment to reducing our carbon footprint, we have a robust sustainability strategy and policy that encompasses every aspect of our business.

The following six pillars are part of our sustainability focus for OSA.


Quality control is much higher, as modules are assembled in a factory setting and not a construction site.


OSA supports rural communities, creating jobs in areas that do not have as much construction employment.


OSA reduces cost and time, as there is less waste of materials and less time spent on non-value-add activities.

Health & Safety

OSA guarantees the highest possible standards of safety through standardisation and high-risk activity minimisation.


Operatives have improved employee facilities & working conditions, leading to higher levels of morale and employee wellbeing.


Eradication of noise in industrial or residential areas, ease of carbon reporting, reduced traffic, and reduced numbers of people on site.
