	“The location of the reference monuments and monolith marker points should be established along the proposed base line... The base line should be located so that at completion of construction the line of sight between the reference monuments is unobstructed. Also, consideration should be given to location based on least interference from other operations during alignment measurements. The reference monuments should be located off the structure a sufficient distance not to be influenced by movement of the structure. In instances where this is impractical, the first marker point at each end of the structure may be used as reference points providing the end blocks have low and level foundations. The reference monument elevation should be the least practical vertical height above the structure to maintain the least angle between the precision instrument and monolith marker points. Normally two marker points will be installed on each side of a vertical joint between monoliths. An overall plan and a section between reference monuments and first marker point on the structure should be part of the design submission.”<ref name="EM 1110-2-4300">[[Instrumentation for Concrete Structures (EM 1110-2-4300) \| Instrumentation for Concrete Structures (EM 1110-2-4300), USACE, 1987]]</ref>		“The location of the reference monuments and monolith marker points should be established along the proposed base line...
