The invention disclosed is for a manner of construction of an elevated annular platform, generally elevated and which rotates. The platform includes a means of rotation between the annulus and the foundation. The platform is formed of reinforced concrete material, poured in one pour. The mould for the platform comprises a plurality of bail sections which, in number, correspond to the bails of the finished platform, and inner and outer edgings. Each bail section includes support sides, which are secured to the inner and outer edgings, and a base panel. The panels are made from a material which, when the annulus is formed, bonds to the concrete to form a unitary structure. The moulding thus forms an integral part of the completed platform, and is not removed after construction.
