TASKS TO BE COMPLETED. 3.1. Design Surveys The State will request design surveys on an as needed basis. The Engineer’s Surveyor shall perform tasks including, but not limited to the following: • Obtain or collect data to create cross-sections and digital terrain models. • Locate existing utilities. • Locate topographical features and existing improvements. • Provide details of existing bridge structures. • Provide details of existing drainage features, (e.g., culverts, manholes, etc.). • Locate wetlands. • Establish additional and verify existing control points. Horizontal and Vertical control ties must be made and tabulated, to other control points in the vicinity, which were established by other sources such as, the National Geodetic Survey (NGS), and the Federal Emergency Management Agency (FEMA), and any other local entities as directed by the State. • Locate existing right-of-ways. • Review right-of-way maps. • Locate boreholes. • Perform hydrographic surveys. • Update existing control data and prepare survey control data sheets, as directed by the State for inclusion into a construction plan set. The Engineer’s Surveyors shall also prepare a Survey Control Index Sheet and a Horizontal and Vertical Control Sheet(s), signed, sealed and dated by the professional engineer in direct responsible charge of the surveying and the responsible RPLS for insertion into the plan set. The Survey Control Index Sheet shows an overall view of the project control and the relationship or primary monumentation and control used in the preparation of the project; whereas, the Horizontal and Vertical Control sheet(s) identifies the primary survey control and the survey control monumentation used in the preparation of the project. Both the Survey Control Index Sheet and the Horizontal and DocuSign Envelope ID: 5A2DC6EC-64DB-4A02-A984-B96FAAFF8279 PeopleSoft Contract No. 7490 Legacy Contract No. 12-7IDP5009 Vertical Control Sheet(s) must be used in conjunction with each other as a set. The State’s forms for these sheets can be downloaded from the State’s website. The following information shall be shown on the Survey Control Index Sheet: • Overall view of the project and primary control monuments set for control of the project • Identification of the control points • Baseline or centerline • Graphic (Bar) Scale • North Arrow • Placement of note “The survey control information has been accepted and incorporated into this PS&E” which shall be signed, sealed and dated by a Texas Professional Engineer ...

TASKS TO BE COMPLETED. The Engineer’s Surveyor shall perform the following tasks:
TASKS TO BE COMPLETED. 3.1. Design Surveys The State will request design surveys on an as needed basis. The Engineer’s Surveyor shall perform tasks including, but not limited to the following: Obtain or collect data to create records in PAI on a statewide basis Obtain or collect data points and linear features to create GIS maps showing non- compliant ADA conditions. Locate existing above ground utilities that are in conflict with existing pedestrian facilities. Locate topographical features and existing improvements as necessary. Locate existing drainage features, (e.g., culverts, manholes, etc.) as necessary. Locate existing right-of-ways as necessary. Review right-of-way maps as necessary.
TASKS TO BE COMPLETED. Aerial Photography. The Engineer’s Surveyor shall provide aerial photography for low altitude aerial mapping appropriate for detailed design. Limits of aerial photography and TIN shall be as follows: Southern Section description – beginning 1000 feet south of the intersection of US 69 and FM 1003 and ending 3000 feet north of intersection of US 69 and Post Oak Road; o Collect aerial photography and TIN coverage 300 feet east and west of the centerline of existing US 69. Northern Section description – beginning 3000 feet north of the intersection of US 69 and Post Oak Road and ending 100 feet north of the intersection of existing XX 00 xxx Xxx XX Xxxxxxx 00 xx Xxxxxx, Xxxxx; o Collect aerial photography and TIN coverage from 500 east of the centerline of existing US 69 pavement and 150 west of the center of the TxDOT owned Railroad Trail. The Engineer’s Surveyor shall provide horizontal ground control that meets standards of accuracy required by the State and as described in the TxDOT Survey Manual, latest edition, or the TSPS Manual of Practice for Land Surveying in the State of Texas, as may be applicable. The Engineer’s Surveyor shall provide vertical ground control that meets standards of accuracy required by the State and as described in the TxDOT Survey Manual, latest edition, or the TSPS Manual of Practice for Land Surveying in the State of Texas, as may be applicable. For purposes of this Contract, all standards and specifications shall be in accordance with established guidelines and recommended or approved by the State. The use of LiDAR Technology (mobile, terrestrial or aerial) will be acceptable when approved by the State and the accuracies of the specified tasks it will be used for are met or exceeded. The Engineer’s Surveyor shall provide digital orthophotos on USB media along with a photo index of the scanned aerial film frames or digital image frames for each frame of photography in the project. The Engineer’s Surveyor shall prepare DGN, DTM and TIN files covering the specific work location, meeting standards and specifications as required. DocuSign Envelope ID: 3834C76D-F898-4EF5-A280-35D1D4DA0CBD Aerial mapping must meet or exceed the requirements for ASPRS Class 1 standard for 1” = 40’ scale mapping with a one foot contour interval. Field verification of adherence to the required accuracy specification is at the discretion of the State. For maps that are not field checked but have been compiled to meet the State’s accuracy standard, t...
TASKS TO BE COMPLETED. All Survey will be provided under a separate contract with TxDOT.
