As growth in the number of large scale scientific facilities continues throughout the UK, there is a corresponding need for established safety standards and processes to be applied throughout the construction and maintenance of systems that are breaking new ground. To meet these demands requires an efficient engineering process backed up by years of experience, with system assurance as an integral part. AEGIS engineering has the experience and ability to tailor the safety process to the needs of the project, removing obstacles to the successful operation of critical systems.
