Aims: To give students the knowledge and skills required to carry out an engineering survey of a small site.
Learning Outcomes:
The succesful student will be able to demostrate the knowledge, understanding and skills required to carry out an engineeirng survey of a small site.
Skills:
Ability to use a range of surveying instruments to acceptable accuracy, to plan execute, and process small surveying projects.
Content:
Object and application of surveys - basic functions of survey instruments - survey planning - assessment of accuracy.
Measurements of distance - direct tape measurements - cumulative errors in chainage measurements and corrections applied. Principles of electronic methods of distance measurement.
Measurement of level - types of levels - levelling procedures and methods of booking - errors - reciprocal levelling - recording and plotting levels.
Measurement of angles - principles and operations of the theodolite - scope of use - instrument errors and adjustments. Usage of theodolite and computation for tacheometry, traverse surveys, triangulation.
After a series of initial practice periods with survey instruments the unit concludes with a survey project consisting of the measurment of a closed traverse around a land plot and its detailed mapping.
