Horizontal and vertical control surveys are developed to create a framework to which other surveys can be compared. The most fundamental aspect of a successful survey and all subsequent activities is accurate, reliable and precise survey control.

It is highly recommended that Vertical Control and Horizontal Control surveys are used during the following construction phases:

  • Underpinning
  • Dewatering
  • Excavation
  • Demolition

Vanguard Construction Solutions works with our client during the construction planning phases to ensure all parties understand and agree, on the requirements for horizontal and vertical control datum. This reduces the likelihood of datum mismatch that can be extremely costly for any project.
