Basic Land Surveying Course Singapore Institute Of Surveyors And Valuers
السعر: 1,500 SGD

    تفاصيل الدورة

    The course covers levelling and total station instrument use and adjustment, misclose distribution, Angle-Bearing-Angle conversion and revision of trigonometry concepts. Introduction to coordinates and explanation of the common survey computations for close and area are also covered.

    Candidates are given practical project work, e.g. closed traverse, series levelling loop and are assessed on both the conduct and results of their work

    The syllabus and structure are subject to revision without prior notice to reflect current changes in technique or technology.

    Introduction to Land Surveying

    Introduction

    • What is land surveying? Explain Plane & Geodetic Surveying. Field & Office Work. Use of surveying for boundary definition, for construction, horizontal control & vertical control.
    • Engineering, cadastral, hydrographic & photogrammetric Surveys.

    Principles of Surveying

    Concept of poiint location by:

    • Trilateration
    • Offsets
    • Traversing
    • Intersection

    The Surveyor’ Work

    • Verify/establish horizontal & vertical controls
    • Location/ refixing the positions of boundary marks in a cadastral survey
    • Carry out a topographical survey
    • Horizontal & Vertical monitoring of structures, dams, tunnels etc
    • Carry out a pre-computation for a setting out survey
    • Setting out building corners, roads, drains etc

    Equipment

    • Measurement of distance: tapes, chains, edmi
    • Measurement of angles/bearings: theodoites, total stations, robotic system
    • Measurement of N,E,Z coordinates: GPS, Total station

    Field Procudure

    • Working from whole to part
    • Recce
    • Planning & obtaining datum for survey
    • Observation & recording

    Horizontal Control Survey

    Establishing horizontal controls using total station &./ or GPS

    • Controls for setting out/traverses
    • Concept of true north, grid north, bearings, angles etc
    • Linear measurement with tapes, chains, edmi
    • Accuracies & errors in linear measurements
    • Method of measuring angles, bearing & their associated errors & accuracies

    Traverses

    • Open & close traverses
    • Datum to commence survey
    • Cadastral survey traverse & connection to ISN marks

    Computations

    • Linear Misclose
    • Precision & Accuracy
    • Adjustments: Bowditch Rule, Transit Rule & Least Square
    • Calculate setting out data
    • Calculate area & volumes
    • Calculate clearances, distance, angles, coordinates

    Vertical Control Survey

    Ordinary levelling:

    • Basic knowledge & Equipment
    • Principle of finding
    • Booking, calculations & checks
    • Accuracy, precision & errors
    • Adjustments

    Perrmanent adjustment

    Applications of levelling:

    • Long & cross sections
    • Contouring
    • Setting out proposed levels
    • Monitoring of settlement markers

    ENTRY REQUIREMENTS

    • Minimum of 1 GCE “O” Level credit; OR
    • 3 GCE “N” Level; OR
    • NITEC

    نبذة عن معهد Singapore Institute Of Surveyors And Valuers

    The Institute comprises 3 divisions: the Land Surveyors, the Quantity Surveyors and the Valuation and General Practice Surveyors. The Land Surveyors play a crucial role in the proper erection of buildings, especially high-rise construction, and the accurate delineation and identification of vertical and horizontal interests in these buildings. The Quantity Surveyors are consulted on the economics of cost in the development or redevelopment process. The Valuers give advice on the values of interests in property upon which all real estate activities are based on. In addition, the Valuation and General Practice Surveyors also comprise real estate professionals dealing in marketing and agency, management and various forms of consultancy on real estate issues.
