The preparatory phase of the project is due to complete this Autumn. and will involve O’Rourke constructing two temporary building.

During construction of the temporary structures O’Rourke and architects BDP will work closely with the Brighton and Sussex University Hospitals NHS Trust to develop designs for the main building ahead of an expected construction start time in early 2016.

Duane Passman, Director of the 3Ts Redevelopment said: “We are now moving into the clinical phase of our decant programme.

“This is when the redevelopment becomes real for most people, with the beginning of construction on site.

“We are pleased to be working with Laing O’Rourke on both these temporary buildings which are key to unlocking the space we need for the redevelopment to go ahead.

“This is an exciting time. What starts as the foundations for a temporary building today will end with patients being treated in brand new, permanent facilities of the highest quality.”

Steve Lloyd, Project Director for Laing O’Rourke said: “Our team has worked very closely with the Trust and the design team in the development of the 3Ts project, so it is fantastic to see the first signs of construction that will enable this important redevelopment to move forward.

“These high quality temporary structures will be imperative to allowing the Royal Sussex County Hospital to continue servicing the local community during the redevelopment period.

“We look forward to finalising the designs for the main building over the coming months as the redevelopment progresses to Full Business Case stage”
