This project required the use of an RSJ channel to carry the roof plate inside the webbing

We started by installing a row of Acrow props on the inside, running parallel to the roof plate

Exposing the original concrete lintels helped us to support the new RSJ during installation

A timber plate was bolted to the RSJ to carry the extension roof timbers

Finally, the new ceiling was suspended to create a flush seamless joint between the new and existing part
