JUN JUN MORENO Professor CE0015L – Fundamentals of Surveying Field Work 7 – Locating Lots and Boundary Mapping Objectives: 1. To examine the contents of a typical survey plan. 2. To identify survey plan errors or missing information if anything evident. Activity Guide: 1. Establish the points 1 and 2 as shown in Figure 1. Figure 1. Points for distance pacing and taping exercise. 2. For high resolution file of Figure 1 – Click this hyperlink. 3. Identify all the survey lot plan contents. 4. Prepare a checklist of shown items and missing items if any. 5. A boundary survey shall include, but not be limited to, the following: Clear and legible field notes containing all pertinent information, measurements and observations made in the course of the field survey. Unless requested otherwise by the client or his/her agent, a plat of survey. A legal description for any parcel surveyed. Unless requested otherwise by the client or his/her agent, monuments or witness points shall be set for all accessible corners of the survey 4. All boundary surveys, also called as plat, the survey shall contain the following: 6. Firm name, address and registration number. 7. Professional land surveyor seal, signature, date of signing, and license expiration date. Rubber-stamp signatures, computer generated signatures or other reproduced signatures are prohibited. 8. Client’s name. 9. North arrow. 10. Scale-written or graphic. 11. Date of completion of field work. 12. Legal description of the property. 13. Legend for all symbols and abbreviations used on the plat. 14. Monuments or witness corners, whether set or found, intended to represent or reference corners of the survey, shall be shown and described as to size, shape and material, and their positions noted in relation to the survey corners. 15. Sufficient angles, bearings or azimuths, linear dimensions and curve data must be shown on the plat to provide a mathematically closed figure for the exterior of the survey. Where record angular dimensions, bearings or azimuths, linear dimensions or curve data exist, such data shall be shown on the plat and distinguished from measured dimensions or data. Area of the survey is to be shown on the face of the plat unless otherwise requested by the client. 16. Where bearing, azimuth or coordinate systems are used, the basis or proper names of the system shall be noted on the plat. 17. If the survey is a parcel in a recorded subdivision, any adjacent rights of way or easements and setback lines shown on the recorded plat that affect the subject parcel are to be shown and dimensioned. 18. Visible physical evidence of possession or occupation either way from the exterior lines of the survey shall be shown and dimensioned. Show visible evidence of improvements, rights of way, easements, or use when requested by the client. Exculpatory statements that attempt to restrict the uses of boundary surveys shall not be affixed to any plat. % Convert the items listed in number 5 and 6 in a checklist format. Then, check the items that is evident in the survey plan drawing in Figure 1. II.

OBSERVATION The researchers observed that due to the sudden rise of temperature there are difficulties that the researchers faced, the high temperature also affected much of the of data gathering process all throughout the field work, when it comes to solving the researchers heavily relied. on the data gathered on the field work IV. RECOMMENDATION The researchers recommend that because of the human errors present in the data gathering process. The researchers recommend that always double check the solved data, and always prepare for the environment in which you would be working in V. DOCUMENTATION
