BTEB Amin Survey Exam study guide
BTEB Amin Survey Exam · Work through your exam, one topic at a time.
The BTEB Amin Survey Examination is a surveyorship credential associated with the Bangladesh Technical Education Board (BTEB), the national body whose website lists technical and vocational programmes, examination results and e-services. Candidates preparing for a surveyor (amin) certificate typically come from technical school and college backgrounds and intend to work on land measurement, construction layout and infrastructure field teams. The BTEB Amin Survey Exam study guide has 6 sections and about 2,397 words.
01Surveying Fundamentals and Chain Surveying
Surveying fixes the relative positions of points on or near the earth's surface. Know the primary divisions: plane surveying (earth treated as flat, valid for small areas) versus geodetic surveying (curvature accounted for).
326 words, about 2 min02Compass and Theodolite Traversing
Compass traversing measures magnetic bearings; theodolite traversing measures angles with greater precision. Know the bearing systems: whole-circle bearing (WCB, 0–360°), reduced bearing (RB, quadrantal), and the conversions.
312 words, about 2 min03Levelling and Contouring
Levelling determines relative heights. Know the instruments (dumpy, tilting, auto level), the staff, and the terms: benchmark, reduced level (RL), back sight (BS), intermediate sight (IS), fore sight (FS), height of instrument (HI), change point, and the line of collimation.
315 words, about 2 min04Plane Table Surveying and Minor Instruments
Plane table surveying plots detail in the field without separate field notes. Know the equipment: plane table, alidade, plumbing fork and plumb bob, spirit level, compass, and U-fork with plumb bob.
307 words, about 2 min05Area and Volume Computation
Area computation uses the trapezoidal rule, Simpson's rule, the mid-ordinate rule, and the coordinate (shoelace) method. Understand when each applies: Simpson's rule needs an even number of equal intervals (odd number of ordinates) and assumes a parabolic boundary; the trapezoidal rule works with any number of equal intervals.
285 words, about 1 min06Setting Out
Setting out transfers design positions to the ground. Know the methods for setting out a building: 3-4-5 method (Pythagoras), offset method, and theodolite method.
