Abstract :
The Relativistic Heavy Ion Collider consists of two interlaced plane rings, a pair of mirror-symmetric beam injection arcs, a spatially curved beam transfer line from the Alternating Gradient Synchrotron, and a collection of precisely positioned and aligned magnets, on appropriately positioned support stands, threaded on those arcs. RHIC geometry is defined by six beam crossing points exactly in a plane, lying precisely at the vertices of a regular hexagon of specified size position and orientation of this hexagon are defined geodetically. Survey control and alignment procedures, currently in use to construct RHIC, are described
