SURVEYING JOB DISCRIPTION

SURVEYING JOB DISCRIPTION

    The job of the land surveyor is the survey carried out to demarcate the boundaries of properties meant for legal purposes.  It also retraces legal description(s) from the deed belonging to the subject property by locating actual reference monumentation and verifying its correct position.

       So the land surveyor is often forced to consider other evidence such as fence locations, wood lines, monuments on neighboring property, parole evidence and other evidence.

      Control Surveys are the surveys carried out to establish highly accurate horizontal and vertical of selected point or stations. This point are then used as reference other surveys, the selected stations are well spaced to cover a large area.

       They are most often 1/2" or 5/8" iron rebars rods or pipes placed at 18" minimum depth. These rods and/or pipes usually have an affixed plastic cap over the top bearing the responsible surveyors' name and license number.

         In addition to rods/pipes, 4x4" concrete posts are often used at corners of large parcels or anywhere that would require more stability ( ex- beach sand). They are placed at a depth of 3 feet. In places where there is asphalt or concrete, it is common to place nails or

Aluminum alloy caps to re-establish boundary corners. Marks should be durable, stable, and as "permanent" as possible.

      The aim is to provide sufficient marks so some marks will remain for future re-establishment of boundaries. The material and marking used on monuments placed to mark boundary corners are often subject to state laws.

        Cadastral surveys are licensed by state governments. In Nigeria only Registered Surveyors are allow to carry out cadastral surveys.

Legal surveys are usually usually made for one of the following process.

•      To subdivide a parcel on land into various pieces according to a specific plan showing the predetermined size, shape and location for each parcel
• · To carryout proper demarcation of land in dispute as claimed different parties involved
•  Re-establish and mark the corners of original land boundaries. The first stage is to research relevant records such as land titles (deeds), easements, survey monumentation (marks on the ground) and any public or private records that provide relevant data. In order to properly establish accurate position of survey markers, it is then necessary for measurements to be taken. This is achieved by placing a [total station] over the points and recording distances taken with the [EDM].The data is analyzed and comparisons made with existing records to determine evidence that can be used to establish boundary positions. The bearing and distance of lines between the boundary corners and total station positions are calculated and used to set outland mark the corners in the field. Checks are made by measuring directly between pegs places using a flexible tape. Subdivision of land generally requires that the external boundary is re-established and marked using pegs, and the new internal boundaries are then marked.
