Ground Survey. 2.1 The Engineer will provide a boundary and topographic improvements survey of the entire roadway corridor. Survey information beyond/outside the ROW will require permission from the impacted property Owner(s). Requests for access from private property owner(s) and surveys in private property will be the responsibility of the Engineer.
Ground Survey. The ENGINEER will acquire ground survey information along the project corridor as depicted in the attached Exhibit A. • The topographic survey shall be prepared at 2-foot contour intervals for a 100-foot corridor along the preferred alignment, with elevations tied to NAVD 88 datum. Horizontal datum shall be VA State Plane Coordinate North (NAD83). For budget fee purposes it is assumed the additional corridor to be surveyed will be linear feet. • All existing and visible surface features along the project corridor shall be located and plotted at a scale of 1 inch = 40 feet over the 100-foot wide project corridor. Trees larger than 6-inches in diameter shall be identified by diameter and type. Edges of wooded areas will be located. The surveys shall include all observed physical features including meter vaults, valve boxes, manhole rims and other buried objects that have a visible representation, storm culverts, edges of pavement, tree lines, utility poles, manhole covers, vaults, etc. The site surveys shall include the location of all building corners, curb lines and above grade structures, telephone poles, including electrical equipment (e.g., utility transformers). The survey shall include inverts of all gravity pipes. • ENGINEER certifies that all ground survey work shall be accurate to horizontally and feet vertically. feet • The VA state plane grid will be established and shown as well as the property corners, property lines, yard lines, setbacks and buffer yards. Owner information will be provided for all properties shown, as well as easement and right-of-way information. • Surveys shall also include staking out the soil borings, and picking up the horizontal and vertical locations for geotechnical engineering analysis, as well as the location of all flagged wetlands along the project corridor. • Control points will be established for inclusion in the design documents, as well as for use by the Contractor during stakeout. Location and spacing shall be as deemed appropriate for construction; however, a minimum of control points are envisioned. This will include all initial survey control and tie to the horizontal and vertical datum for the base mapping. • Staking out the alignment for construction (on a case by case basis)
Ground Survey. The field survey was carried out around radial distance of 10 km from the project site. The survey consisted of traversing the study area, cross-checking of identified features with those represented on the map. Field notes were kept in the form of log sheets that recorded information pertaining to co-ordinates, photographs and identified landuses. Additional features identified or remarks made against existing interpretation were also recorded. The field survey was carried out around radial distance of 10 km from the project site. Kadam’s land use and land cover Functional Area Expert visited the site for quality check of the map. GPS readings were taken during the surveys wherever it was felt that additional confirmation in interpretation of the data and also observations of land features were noted. Additionally, spot checks were also done to confirm the land use / land cover interpretation even where confidence of interpretation was high. Table 3-2 enumerates the land features and its corresponding GPS readings of all the ground truthing locations selected.
