Topographic Survey. The Professional shall obtain a topographic and utility survey as described below.
4.1.1. The Professional shall tie in all existing surface topographic features and structures within the survey limits shown in Figure 1. This survey shall include: tops of curbs, edges of pavement, pavement materials, driveways, sidewalks, retaining walls, drainage structures (top, edges and flow line), channels and drainage ways (tops, toes and flow line), manholes (rim, flow lines and diameters of pipes, type of material and photographs of the inside of manholes and drainage structures), including the same survey data for upstream and downstream manholes and structures that are outside of the survey limits for all gravity wastewater and drainage lines within the survey limits. Visible valves, meters, clean-outs, slabs, utility signs, utility poles and structures, fences, landscaping features, shrubbery, trees (including the approximate drip-line), tree canopies, buildings (edges within the survey limits) mailboxes, etc. Trees shall be tagged and tabulated by size and species specific in compliance with the City of New Braunfels Tree Preservation ordinance as defined in the City of New Braunfels Zoning Ordinance Chapter 5.3- 5i. The survey limits shall extend approximately 100 feet on intersecting streets. The Professional shall provide sufficient ground shots to create one (1) foot contours for the Project.
4.1.2. The Professional shall conduct a utility survey and locate existing utilities within the Project boundary in Figure 1. The Professional shall contact all utility service providers by calling Texas 811 and the NBU Project Manager to coordinate flagging of existing franchise utilities. The Professional shall request drawings of existing agency and municipal owned utilities and shall include locations of these utilities in the survey. The Professional shall tie in the locations of the discovered utilities on the survey. The Professional shall bear all costs for the Services associated with utility locates.
4.1.3. The Professional shall locate up to ten (10) geotechnical borings and tie them in to the Project survey.
4.1.4. The Professional shall set and install control points and/or benchmarks as required for the survey work (minimum 1-foot intervals). The Professional shall provide horizontal and vertical coordinates of the benchmarks in the required coordinate system and datum and show the benchmarks on the survey drawing.

2. Limits of survey shall be right-of-way to right-of-way plus 10 feet beyond each right-of-way line for 250 feet north, south and east of the intersection. Significant pavement and curb damage will also be noted. All sanitary and storm sewer lines will be traced out to the next available access point outside of the right-of-way.
3. All topographic data will be provided as an Adobe PDF file and will be signed and sealed by a RPLS, along with AutoCAD Files.
4. XXX will provide a CSV Points file of all points and control.
5. XXX will establish horizontal control referenced to Texas Coordinate System, South Central Zone and referenced to NAD 1983.
6. Vertical control shall be based on NAVD 88.
7. All control will be set on the site and shown on the final drawings.
8. XXX will contact Texas One-Call and request all public and private utilities be delineated prior to the survey to XXX Level B standards. These markings will be included in the final drawing. Ticket number and contact information will be forwarded to the Engineer.
9. XXX will locate all visible improvements and utilities along the project limits including:
a. Major topographic break lines, ditches, drainage features;
b. All areas will have elevations at a minimum of a 50’x50’ grid;
c. All buildings, towers, tanks or other significant physical structures;
d. Sidewalks, parking areas, fences, trees, shrubs, irrigation system components or other landscape facilities;
e. Spot elevations at the intersection including all pavement joints within the intersection;
f. Back and gutter of curb, signage, and roadways.
g. All pavement striping, traffic loops, and construction joints within the survey limits will be shown.
Topographic Survey. The scope indicates the right of way will be determined from "a combination of record data and any monuments." What do you propose for areas where no record data is available?
Topographic Survey. 2.1 Notify affected property owners of pending survey.
2.2 Research and verify existing easements and plats of record at county courthouse for the property.
2.3 Locate existing boundary markers at the time of the survey.
2.4 Locate all existing above ground features within the established survey limits. Take a sufficient frequency of elevation shots to establish reasonable accuracy for contours to be shown on a one foot interval. Provide building floor elevations available at the time of survey through existing exterior doorways made available by Client and/or Owner, as necessary.
2.5 Show utilities, above and below ground, located in the field at the time of the survey by the utility companies, Client or other authorized agents of utility companies. Xxxxxxxxx will contact South Dakota One Call System, if available, to arrange for the location of utilities at the time of survey.
2.6 Prepare topographic survey utilizing AutoCAD Civil 3D for use in development of plan documents.
Topographic Survey. The first task performed by F&L will be to complete a detailed topographic survey of the two Project areas to serve as the basis of design for the proposed improvements and for development of a base plan. The survey will be conducted as follows: • Perform field topographic surveys within the Project limits including 20-feet on each side of the existing water main to capture visible public and private improvements, driveways and utilities, including existing U.S.A. markings within street right of ways. San Francisco Office: 000 Xxxxxxxxx Xxxx Xxxx, Xxxxx 0000 San Mateo Office: 000 Xxxxx Xxx Xxxxx Xxxxx Xxxxxxx Office: 000 Xxxxxxxxxx Xxxxxx, Xxxxx 000 Xxx Xxxxxxxxx, XX 00000 San Mateo, CA 94401 Xxxxxxx, XX 00000 Tel: (000) 000-0000 Tel: (000) 000-0000 Tel: (000) 000-0000 xxx.xxxxxxxxxxxxx.xxx Xx. Xxxxxxxx Xxxxxxx, P.E. Page 2 of 6 2nd REVISION - February 6, 2020 • The limit of work within street right of ways will be the back of sidewalk. Where no sidewalk exists, limit of work will be 5 feet from edge of pavement. • Horizontal control and vertical control will be based on City Benchmarks and GPS control. • Inverts, pipe sizes and direction of flow will be collected for sanitary sewer and storm drain lines (if any) within the limits of work. Storm drain and sanitary sewer appurtenances will be dipped. • All surface expressions of existing water line utility lines obtained from available maps will be field verified. • Easements, if any, shown on recorded maps of the area will be shown on the survey map and base plan. • All visible clean outs will be located. • Existing utility location research will be performed including review of available City and utility owner drawings. Approximate utility locations interpreted from available drawings will be shown on the Project base plan1. • Survey information will be translated to AutoCAD drawings for development of the Project base plan and associated construction documents. • The topographic survey will also include estimated property lines and right of way (ROW) lines as shown on available City or County provided maps.
Topographic Survey. Inspection of developer paid construction project.
Topographic Survey. Provide topographical survey and cross sections along the proposed alignment. Typical roadway cross sections will be will not be taken (all survey data points will have X,Y & Z values – deliverable is 2D DGN file). The field data will be sufficient to create a detail planimetric view of the survey project limits. GeoSurv/TSC will invert storm manholes and inlets and invert sanitary manholes, in particular near the intersection where underground pipes may be crossing the four corners of the intersection where a proposed traffic signal may be located. GeoSurv/TSC will not access electrical and telephone manholes. GeoSurv/TSC will tie trees over 3” in diameter when isolated as for landscaping purposes but will only locate edge of a tree line for wooded areas. Field crews will locate utility tone marks placed on the ground by contacting Texas One-Call. We will locate visible existing utilities toned marked by the pipeline companies, municipal utility districts (MUDs), Fort Bend County, and private utility agencies to obtain locations of existing utilities and depths of existing pipelines in support of the Level B Subsurface Utility Surveying effort. We will contact Texas811 (1-request to have underground utilities marked). Traffic Requirements – We will locate traffic infrastructure (pole foundations, cabinet, service etc.), signs and existing pavement markings. It has been identified that locating concrete construction joints and expansion joints are not necessary for this intersection. Perform surveying services to establish the Apparent Right-of-Way lines (A.K.A. Project Limits). No abstracting services or very limited abstracting services will be performed to obtain plats and existing ROW maps under this task. The “Project Limits Line” established under this task will not meet the requirements for establishing existing right-of-way lines based on TBPE&LS requirements; therefore, text callout for this line cannot imply that the TBPE&LS requirements were followed to establish the locations of the right-of-way lines. The Project Limits/Apparent ROW will be shown in the Topographic Survey file or be a reference file to the base Topographic Survey file.
Topographic Survey. Topographic survey to transfer the Bench Mark (B.M.) value from nearest known location within the Silchar - Bhanga corridor to few important stations along the river (based on his judgement) and also to the locations within 5 Km range of dredging site will have to be undertaken as a primary activity before any dredging work can be started because the B.M will act as control points for dredging depths. This survey is to be undertaken by the Contractor, the cost of such survey and erection of bench marks shall be included in the cost of dredging activity and is not to be considered as an additional activity having separate cost.
Topographic Survey. Perform topographic survey within the Project limits of natural and manmade features along the water main routes to develop base sheets for Project drawings.
Topographic Survey. TREKK will develop a topographic basemap that includes data extracted from the UAV LiDAR.
