1、08-11 02 21 00 - 1 SECTION 02 21 00 SITE SURVEYS PART 1 - GENERAL 1.1 DESCRIPTION This section specifies the gathering of research documents, performance of a topographic survey and preparation of a topographic survey map. 1.2 DEFINITIONS A. Professional Land Surveyor: One who possesses a valid stat

2、e license as a “Professional Land Surveyor“ from the state in which they practice. B. Professional Civil Engineer: One who possesses a valid state license as a “Professional Civil Engineer“ from the state in which they practice. For this section, the term “surveyor“ shall also include Professional C

3、ivil Engineers authorized to practice Land Surveying under the laws of the state in which they practice. PART 2 - EXECUTION A. The surveyor shall research available public records for all mapping, monumentation, plats, governmental surveys etc. that may pertain to the subject property. Research all

4、applicable public utilities for substructure data such as sewers, storm drains, water lines, electrical conduits etc. B. The survey shall be performed on the ground in accordance with the current “Accuracy Standards for Land Title Surveys“ as adopted, from time to time, by the American Congress on S

5、urveying and Mapping, the National Society of Professional Surveyors, and the American Land Title Association. C. The surveyor, when applicable, shall consult with the project Architect to determine scale of plat or map and size of drawings. D. The surveyor shall furnish two sets of prints of the pl

6、at or map of survey and an electronic CADD file. If the plat or map of survey consists of more than one sheet, the sheets shall be numbered, the total number of sheets indicated and the match lines be shown on each sheet. E. On the plat or map, the survey boundary shall be drawn to a convenient scal

7、e, or the scale designated by the Architect, with the scale clearly indicated. A graphic scale, shown in feet or meters or both, shall be included. A north arrow shall be shown and when practicable, the plat or map of survey shall be oriented so that north is at the top of the drawing. Symbols or ab

8、breviations used shall be identified on the face of the plat or map by use of a legend or other means.

13、e boundary represented by bearings and distances, and the length and radius of each curve, together with elements necessary to mathematically define each curve. The point of beginning of the surveyors description and the basis of bearings shall also be shown. 7. When record bearings or angles or dis

14、tances differ from measured bearings, angles or distances, both record and measured bearings, angles, and distances shall be clearly indicated. If the record description fails to form a mathematically closed figure, the surveyor shall so indicate. 8. Measured and record distances from corners of par

15、cels surveyed to the nearest right-of-way lines of streets in urban or suburban areas, together with recovered lot corners and evidence of lot corners, shall be noted. The distances to the nearest intersecting street shall be indicated and verified. Names and widths of streets and highways abutting

The identifying titles of all recorded plats, filed maps, right of way maps, or similar documents which the survey

18、represents, wholly or in part, with their appropriate recording data. The survey shall indicate platted setback or building restriction lines which have been recorded in subdivision plats or which appear in a Record Document which has been delivered to the surveyor. Contiguity, gores, and overlaps a

19、long the exterior boundaries of the survey premises, where ascertainable from field evidence or Record Documents, or interior to those exterior boundaries, shall be clearly indicated or noted. Where only a part of a recorded lot or parcel is included in the survey, the balance of the lot or parcel s

20、hall be indicated. 10. All evidence of found monuments shall be shown and noted. All evidence of monuments found beyond the surveyed premises on which establishment of the corners of the survey premises are dependent, and their application related to the survey shall be indicated. 11. The character

21、of any and all evidence of possession shall be stated and the location of such evidence carefully given in relation to both the measured boundary lines and those established by the record. An absence of notation on the survey shall be presumptive of no observable evidence of possession. The term “po

22、ssession“ does not imply “ownership“. 12. The location of all buildings upon the plot or parcel shall be shown and their locations defined by measurements perpendicular to the boundaries. If there are no buildings, so state. Proper street numbers shall be shown where available. 13. All easements evi

23、denced by a Record Document which have been delivered to the surveyor shall be shown, both those burdening and those benefiting the property surveyed, indicating recording information. If such an easement cannot be located, a note to this affect shall be included. Observable evidence of easements an
