What We Do

Decommissioning is the safe shut-down of operation of facilities used for industrial, chemical, power or nuclear purposes. As the sites often contain highly sensitive and dangerous materials, the process of planning and assessing risk is substantial, and is then followed by the careful and coordinated removal of each element before the demolition phase begins.

Keltbray provides specialist input for the decommissioning phase of projects covering the period from plant closure to commencement of demolition. During this stage of the works, characterisation surveys are used to identify the location and quantum of potentially hazardous materials, plants cleaned and de-energised, and value engineering applied to maximise the return from saleable assets. Keltbray Decommissioning is an industry leader in this field, covering a wide range of highly regulated and heavy industries including nuclear, petrochemical, pharmaceutical and the power sector.

Decommissioning is provided by the following Keltbray teams:

Enabling works are part of the construction process that ensures the construction site is able to facilitate the build works required, including establishment of required site accommodation, formation of vehicle and personnel entrances, security fencing and visual indicators of what is taking place on the construction site.

Along with these activities, assistance in the client planning obligations and deliverables encompassing environmental cultural and social can be undertaken. Civil engineering works in general covers the onsite clearance and remediation of sites and the beginning of the new construction process where new foundations and sub structure works are undertaken. Keltbray has a proven track record in the delivery of varying complex and challenging civil engineering projects utilising our in house design capability and specialist delivery teams on time and within agreed budgets using innovate techniques with due consideration given to the surrounding environment and the health, safety and wellbeing of all parties involved or affected by the works at any point.
