Group project assignment. 400 Level GET 402 Engineering Project I (2 Units: C; PH 90) Learning Outcomes At the end of this course, the students should be able to: 1. Complete the design phase of a complex engineering problem sourced from industry or community during the SIWES III programme. 2. Demonstrate the connection between engineering product-making and the theoretical courses they have learned following the applicable industry best practices. Course Contents In the second semester of the 400-level students, preferably in groups, work from the university on the identified industry or organization to tackle industry complex engineering problems. Theoretical issues may be provided by the department faculty or industry experts. During the vacation, students will now work full time with the organisation/industry on the project as part of the SIWES III. The students can also go beyond the department and engage in multidisciplinary undertakings. Literature survey, review of existing systems etc. must be achieved to a satisfactory extent. GET 404 Engineering Valuation and Appraisal (2 Units: C; LH 30) Learning Outcomes At the end of this course, the students should be able to: 1. Identify at least three (3) objectives of engineering valuation work, valuer's primary duty and responsibility and valuation terminologies. 2. Describe at least four (4) Valuer's obligation to his or her client, to other valuers, and to the society. 3. Demonstrate with example the engineering valuation methods, valuation standards, and practices. 4. Prepare engineering valuation and appraisal reports and review 5. Discuss expert witnessing and ethics in valuation. 6. Determine price, cost, value, depreciation and obsolescence in real property, personal property, personal property, machinery and equipment, oil, gas, mines, and quarries valuation.
