NEW JERSEY INSTITUTE OF TECHNOLOGY Department of Mechanical and Industrial Engineering COURSE EM691 Cost Estimating for Capital Projects INSTRUCTOR Randy Reagan Email: reagan@https://www.doczj.com/doc/266630464.html, Homepage: https://www.doczj.com/doc/266630464.html,/~reagan/. TEXTS Engineering Economy, Sullivan, Wicks, Koeling, 14th edition, Pearson, 2009. Note: At the time the 14th ed. text was selected Pearson advised NJIT that a 15th edition would be available in the fall of 2011. However we recently learned that the first printing of the 15th edition was completed in December 2010 and the 15th edition is now available. The 15th edition is almost identical to the 14th edition and students who purchase the 15th edition should be able to study all the course material by using the more recent text. However please be advised that some of homework problems and problem numbering have changed with the 15th edition and therefore students purchasing the 15th edition will be responsible for synchronizing to homework problems specified in the 14th edition. REFERENCES Other related reference materials have been placed on reserve at the library. https://www.doczj.com/doc/266630464.html,/w/page/16142929/Reagan COURSE FORMAT This course will be delivered via a eLearning format where students are responsible for learning by self-study without in-person lectures. Students will be guided through a series of learning sessions by the instructor however students must lean heavily on the assigned text as a key resource and review lecture notes provided through Moodle. The homework is an Excel project which reinforces topics covered in the learning sessions. Several synchronous internet (Wimba) web meetings will be scheduled during the course of the term to cover a summary of the material and to provide a forum for student questions. Students are also able to hold discussion with the instructor via email or pre-arranged meetings during the term. Students are responsible for completing all course exams/deliverables by the specified dates. COURSE MGT Announcements, notes, resources, assignments and due dates will be posted at: https://www.doczj.com/doc/266630464.html,. DESCRIPTION Cost management, estimating and financial techniques used in budgeting, evaluation, planning, and control of capital investments. Emphasis on quantitative financial analysis in capital projects, risk management and decision techniques commonly used in Engineering Management. TOPICS The course will cover the following topics: 1.Introduction to Engineering Economics 2.Cost Concepts 3.Cost and Financial Management 4.Cost Estimating 5.Time Value of Money 6.Project Evaluation 7.Project Selection 8.Depreciation and Taxes 9.Pricing & Exchange Rates 10.Breakeven and Sensitivity Analysis 11.Risk Analysis 12.Capital Budgeting 13.Multiattribute Decision Making EXAMS Exams are intended to cover all material in the assigned text chapters, lecture notes and homework. Students will be asked to solve a set of problems very much like the examples in the text or the homework. All exams will be proctored according to guidelines that will be discussed prior to the exam. EXCEL PROJECT Students will complete a comprehensive set of homework problems in Excel. Students may optionally work in groups (e.g. 2 to 3 max in a group) for the purpose of comparing solutions however each individual is responsible to submit their own original project work for grading. Projects must be developed according to detailed instructions provided with the assignment and submitted by the due date to receive full credit. . GRADING Mid-Term Exam 30%, Excel Project 35%, Final Exam 35% POLICIES Students are responsible for adhering to all university policies including the policies for academic integrity. Additional policies emphasized in this course may be found at the course Moodle site.
