3 • HTCB construction and installation essentially requires the installation to be in conformance with the plans, any special provisions that exist, and shop drawings prepared by or for the manufacturer of the system being installed. • At least one state requires reference markers to be placed on the anchors with control reference markers nearby to monitor possible anchor movement over time.
