The project survey datum, survey control points, site and equipment calibration, electronic files, inspection methods, conflict resolution, and construction staking needs will be discussed at the preconstruction meeting.
5-1.25B Definitions automated machine guidance: Technology that uses one or more positioning devices, such as GNSS, robotic total stations, or rotating laser levels, to determine line and grade, or control the real-time position of construction equipment using onboard computer equipment.
California Coordinate System of 1983 (CCS83): California Coordinate System as defined in Public Resource Code §8801.
Caltrans Spatial Reference Network: The Department owned and operated GNSS real-time positioning network. This network is used to collect data to be used for the design and construction of transportation improvement projects.
digital construction model: Electronic three-dimensional model of the project’s proposed design infrastructure used by the Contractor's AMG equipment.
digital design model: Electronic three-dimensional model consisting of roadway design elements including alignments, profiles, and cross sections representing the finished grade.
digital terrain model: Electronic three-dimensional model that represents the original ground before job site activities begin.
global navigation satellite system: Constellation of orbiting satellites used to determine the geographic location of a user's receiver on the surface of the earth.
GNSS base station: Single ground-based instrument consisting of a GNSS receiver, antenna, and telemetry equipment that provides GNSS corrections to other GNSS receivers. Base stations can be set up temporarily or permanently constructed. Multiple base stations can be combined into a GNSS real-time network.

Convert the electronic design files to a format compatible with your AMG system.
Digital design model information may not exist for certain project features. The Department places stakes under these circumstances.
The Department provides you with updated electronic data whenever the Engineer determines a plan change materially affects the finished grade. For minor grade changes, the Department may place stakes and marks at the discretion of the Engineer.
