Common use of Reflectors Clause in Contracts

Reflectors. Slope face deformation can be measured directly by optical surveying methods reflector prisms attached to selected nails allow for electronic deformation measurements of discreet points on the soil nail wall face. The survey system is typically capable of measuring horizontal and vertical displacements to accuracy of 3 mm (0.12 in.) or better.
