Engineering Surveying Quiz: Questions & Answer #1
Define Engineering Surveying
Engineering survey deals with the survey methods, processes and solutions involved in the reconnaissance, design, construction and erection of new structures, or in the reconstruction or operation of existing engineering structures.
Engineering surveying could include the setting out of works on the ground, which involves working from the plane to the ground.
2. Of What Use is Engineering Surveying to a Civil or Construction Engineer?
Engineering surveying may be used for land management agricultural purposes, the reconnaissance, surveying and development of mineral resources, and the design, erection, installation and operation of complex industrial equipment, experimental devices and structures for scientific purposes.
3. Describe the three stages involved in the process of any form of Engineering Surveying
1. Planning: This is also known as taking a general view or reconnaissance. At this stage, an overall picture of what is obtained before any type of survey work is undertaken, with purpose of the survey has to be decided. Similarly, the accuracy to which measurement are determined in order to overcome obstacles, solve field problems and avoid errors are set out. Survey cost is also determined at this stage. There are two types of reconnaissance survey viz, office and filed reconnaissance.
2. Field Work (Measurement of Observations): There are two forms of measurement required in any type of engineering survey. They are:
(a) Linear Measurement: This is the measurement of distances between points on the earth’s surface. They may be horizontal or vertical.
(b) Angular Measurement: Angular measurement involves the measurement of the angles between reference directions or survey lines in a horizontal or vertical plane. These forms of measurements are used in the basic methods of surveying.
3. Presentation: Survey measurements presentations are done in the form of maps, plans, mathematical, graphs, diagrams, geometric and stereoscopic terrain models, etc., which are recorded in a suitable manner on the drawings by scale representation by the use of conventional signs and by the tabulations of notes with the measured and calculated data.
