Replace section 5-1.24 with:

5-1.24 CONSTRUCTION SURVEYS

5-1.24A General The Department places stakes and marks under the chapter, "Construction Surveys," of the Department's Surveys Manual.

Submit construction staking request for Department-furnished stakes and ensure:

1. Area is cleared and prepared for stakes

2. Request For Construction Staking form is complete with project and contact information, reference alignment, offset and priorities listed, and completion dates

After submittal, the Department starts staking within 2 business days.

The Department will complete the requested staking. The Contractor must plan for the time required by Department surveyors to complete the staking.

Preserve stakes and marks placed by the Department. If the stakes or marks are destroyed the Department replaces them at their earliest convenience and deducts the cost.

5-1.24B Department Construction Surveys for Automated Machine Guidance The Department will provide a project control referenced to the State Plane Coordinate System compatible with the project datum. These physical points must be used by all positioning system users on the site.

The Department may provide grid coordinates for control points, at acceptable locations provided by the Contractor, where the Contractor can install the Contractor’s global navigation satellite system reference station receiver.

For slope stakes and rough grade stakes, the Department sets 6 survey control points or 2 per mile, whichever is greater.

The Department sets slope stakes and rough grade stakes at:

1. Conform stations

2. Beginning and end of each alignment

3. Midpoint or every 200 feet, whichever results in a greater number of stakes, on a curve of less than

1,500 feet

4. Every 500 feet on tangents and curves of 1,500 feet or more

For final grade, the Department sets stakes under the section, "Final Grade Stakes," of the Department's Surveys Manual, or at your request the Department sets survey control points under the sections, "Automated Machine Guidance (AMG)" and "Supplemental Project Control," of the chapter, "Construction Surveys," of the Department's Surveys Manual at:

1. Conform stations

2. Beginning and end of each alignment

3. Midpoint or every 100 feet, whichever results in the greater number of stakes, on a curve with a radius of 1,200 feet or less

4. Midpoint or every 200 feet, whichever results in the greater number of stakes, on a curve with a radius of more than 1,200 feet

5. Every 200 feet on a tangent

At your request and under the chapter, "Construction Surveys," of the Department's Surveys Manual, the Department provides (1) staking for intersections, clearing, fencing, drainage, curbs, structures, abutment fill, walls, and miscellaneous areas and (2) additional survey control or staking for earthwork in areas where global navigation satellite system coverage is inadequate for AMG.

Replace section 5-1.25 with:

5-1.25 AUTOMATED MACHINE GUIDANCE

5-1.25A General Automated machine guidance (AMG) must be used by and for the Department to perform earthwork. Any positioning equipment used for AMG must meet accuracy requirements to comply with staking tolerances specified in section titled "Typical Department-Furnished Construction Stakes" in the Department's Surveys Manual.

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 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.

GNSS correction service subscription: Subscription service to receive GNSS corrections for GNSS positioning through a private GNSS real-time network. Corrections are typically received via cellular wireless data services.

GNSS real-time network: Satellite-based correction service using a collection of ground-based receivers and a central processing center that provides highly accurate location services to users instantaneously over a broad geographic region.

GNSS rover: Portable GNSS antenna, receiver, rod, and data collector with telemetry equipment for real-time point measurements.

GNSS site calibration: Process that establishes the relationship between the observed control point coordinates and the established control point coordinates that define the project survey datum.

grid: General term for describing cartesian coordinates. For the purposes of this specification, grid references Northing (y) and Easting (x) coordinates based on CCS83.

National Spatial Reference System (NSRS): Nationwide network of vertical and horizontal control monuments in the United States. CCS83 is aligned to the NSRS.

project survey datum: Time-stamped reference to the NSRS, represented by CCS83 defined by geodetic survey control points on the surface of the earth.

robotic total station: Survey instrument capable of tracking an optical target and providing real-time coordinates of the target to the equipment operator and AMG equipment. A robotic total station unit can provide positioning for AMG if site conditions do not allow GNSS receivers to be used and must also be used where a higher accuracy is required than the GNSS provides, such as structural section elements.

5-1.25C Electronic Files Electronic design files include:

1. Digital terrain model as a TIN surface in DWG format

2. Digital design model representing the finished grade surface as a TIN surface in DWG format

3. Digital datum model representing any roadway prism structural section datum surfaces as a TIN surface in DWG format

4. Design features including the design alignments, profiles, superelevations, catch lines, hinge lines, grade changes, edge of pavement, edge of traveled way, and other elements used to facilitate project design, provided in DWG format

The Department makes electronic design files available as supplemental project information. This information is part of the bid package provided to the Bidders.

You must create the digital construction models (DCM) for use with your AMG system.

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.

5-1.25D Quality Control Plan Submit an AMG QC plan at least 15 days before starting work requiring AMG. The plan must include the following information:
