(b) If needed, CLEC may perform a Field Survey or request the ASAC to arrange for Field Survey to be scheduled within seven (7) business days of receiving the Billing Authorization from CLEC.
(c) If CLEC performs the Field Survey, CLEC will arrange for the location of all existing subsurface facilities in the requested Ameritech ROW.
(d) During the Field Survey, any necessary Make Ready Work will be identified
(e) CLEC will select the location within the rights-of-way for its attachment or the occupancy of the right- of-way subject to approval by the ASAC. Approval will be denied only for safety, reliability or general engineering principles
Field Survey. Field surveys will utilize a combination of in-field landscape assessments, aerial reconnaissance, pedestrian survey, and subsurface testing to survey an area for archaeological and historic resources. While the overall field survey efforts will be initially guided by the output of the GIS Model (see above), the field crews will further utilize in-field observations to identify landscape characteristics of high, moderate, and low potential for the presence, preservation, and identification of sites. These observations will help to supplement/confirm the GIS Model outputs and potentially allow for future refinements to the Model. The field crew will document, through photographs and field notation, the landscape features present that characterize the archaeological potential of a given survey area. If changes to the project occur, USACE will determine, after consultation with Signatories, Invited Signatories, and Consulting Parties, whether changes to inventory and/or monitoring are required.
Field Survey. November 2004
Field Survey. ENGINEER will conduct a systematic field survey of portions of the APE that are not obscured by asphalt/concrete. The ground surface will be visually examined by an archaeologist for evidence of prehistoric (Native American) or historic (non-Native American) archaeological materials. If necessary, an architectural historian will survey the project for built environment historic period resources (e.g., buildings, bridges, power lines, railroads, mines, or canals).

(b) If needed, CLEC may perform a Field Survey or request the ASAC to arrange for Field Survey to be scheduled within seven (7) business days of receiving the Billing Authorization from CLEC.
(c) If CLEC performs the Field Survey, CLEC will have locates performed to identify existing subsurface facilities in the requested SBC ILLINOIS ROW.
Field Survey. 1. Perform surveying and base mapping services for the design of approximately 7,200 linear feet of sanitary sewer interceptor main from south of Lake Arlington Drive to north of West Pioneer Parkway. Actual project design limits and length shall be as determined in the Preliminary Engineering Report. Field survey limits shall extend approximately 50 feet beyond the limits of each project location.
2. Engineer shall set control points, which shall be based on NAD-83 surface coordinates and the latest version of the City’s GPS Monument Manual located on Public Works & Transportation web page, approximately every 600 feet on both sides of the Project center line. Before setting the control points, Engineer shall obtain approved sketches and specifications from City for the placing of control points.
3. Engineer shall furnish a survey field party to collect all field information necessary to prepare complete and detailed plans, specifications, and contract documents consistent with prevailing engineering standards. This field information shall be based on NAD-83 and the latest version of the City’s GPS Monument Manual located on Public Works & Transportation web page.
4. Engineer shall direct the field party in the following:
Field Survey. 1.1.1 Conduct topography and boundary survey for the PROJECT.
Field Survey. 2.2.1. Survey control data, sketches and photographs, following the PBOT requirements.
2.2.2. Maintenance hole details, including photo documenting maintenance hole interior condition, preparation of detailed sketches for each maintenance hole showing rim elevation, invert elevation at center of maintenance hole, invert elevations of all pipes entering and exiting the maintenance hole, and the size, type and distance from rim of each pipe.
2.2.3. Survey notes.
2.2.4. Survey electronic files (ASCII Point Files with coordinates and elevations along with a description for all points (i.e., secondary control points, center of MHs, angle points, lateral T’s).
2.2.5. Tree inventory spreadsheet, including tree number, coordinates, type (deciduous or evergreen) and diameter at breast height (dbh), per PBOT Survey template.
2.2.6. Easement legal description and exhibits.
Field Survey. A field survey will be completed while potholing activities are taking place. Identification of the utility locations, as well as depth and line size are critical components to incorporate into the design plans. As stated previously, utility conflicts can cause costly construction delays and changes, so identifying that information during the design phase will provide for a smoother construction process. Once surveying and pothole data is compiled, it will be provided to the City and areas of concern will be noted for further discussion. Potholing will be completed based on the approach discussed in Section 1.2.1. Supplemental survey data will also be collected to create the model, prepare easements, and finalize construction documents. The City’s mapping and existing manhole data will be used to the extent possible. A traffic control plan will be prepared and submitted to the City for the survey, geotechnical, and potholing activities. Trihydro will also coordinate with WYDOT in the event boring or potholing activities take place in its right-of-way. The work will be coordinated to avoid causing traffic disruptions to the extent possible, although disruptions are expected to be minimal for this area. Data obtained during this task will be used to complete subsequent tasks. Potholing information and geotechnical information will be provided to the City for review and comment. Details/Assumptions/Approach Conduct supplemental field surveying using State Plane NAD 83 and NAVD88 as necessary and as directed by the City Field survey all geotechnical boring, pothole locations, and utility depths Gather manhole data, where needed The City’s base map will be used Prepare a traffic control plan for surveying and potholing activities Deliverables Provide the City with pothole utility information and supplemental survey
Field Survey. Additional field survey work is also anticipated to locate details not clearly identified on the aerial mapping such as individual trees, and to pick up underground facilities such as drainage inlets. CONSULTANT will include right of way limits, existing horizontal control, utility and drainage facilities on the base mapping using available record data and distribute to the team.
