1. RATIONALE

Field survey is the basic requirement for preparing any engineering maps or drawings.

Field survey can be professionally carried out only when various steps involved in the

survey work are known with skills of operating modern survey equipments. At diploma

level, students are expected to study about these aspects so as to develop their

understanding, performance oriented abilities in order to apply their knowledge in

construction industry.

The course content should be taught and the curriculum should be implemented with the

aim to develop different types of skills so that students are able to acquire following

competency:

Prepare survey maps/drawing after carrying out different kinds of field surveys

using advance surveying equipments.

Find out various physical quantities like length, area, volume, elevations, angles,

latitude, departure, etc by interpreting survey drawings.

3. COURSE OUTCOMES

The theory should be taught and practical should be carried out in such a manner that

students are able to acquire different learning out comes in cognitive, psychomotor

and affective domain to demonstrate following course outcomes.

Use Theodolite for the measurement of horizontal and vertical angle

Calculate the height of objects through a trigonometrical levelling.

students are able to acquire the competencies/programme outcomes. Following is the list of

practical exercises for guidance.

Note: Here only outcomes in psychomotor domain are listed as practical/exercises. However,

if these practical/exercises are completed appropriately, they would also lead to development

of certain outcomes in affective domain which would in turn lead to development of Course

Outcomes related to affective domain. Thus over all development of Programme Outcomes

(as given in a common list at the beginning of curriculum document for this programme)

would be assured.

Faculty should refer to that common list and should ensure that students also acquire

outcomes in affective domain which are required for overall achievement of Programme
