'Sectra’ was a French prefabricated steel formwork design for flats which John Laing and Son Ltd acquired the British rights to in 1962. It was a method of using precision made steel formwork for the placing of structural concrete in 'tunnel' sections in room unit widths and ceiling heights. The units were bolted together in rows on special tracks, with the concrete poured to form the walls and floors in one operation. The formwork was internally heated to accelerate the hardening of the concrete in the mould and the sections were then lifted into position by a tower crane on the construction site. The exact location of the site shown has not been recorded in the negative register but it is believed to be the Darnhill Estate, showing Armadale Court on the left of the group with Kyleakin Court and Bragadale Court behind, and with Staffin Court on the right of the foreground.
