##### Presentation Transcript

1. Warm Up Notes • What is an Assignment? • What’s the objective? • When is it due? • How much effort? • What criteria? • E-mail protocol • Subject: CVEN 349 - ??? ??? • CyberDude • Attachments: DOC, XLS, EXE, VBA, VBS, … … • Attachments: PDF (Adobe), txt, csv, mdb … …

2. Feasibility Studies Module 01.1 Revised: 4/2/2014

3. Purpose • Introduce Students to the concept of “back of the envelope” Plans, Specifications, and Estimates (PS&E) • Develop conceptual solutions to selected local problems.

4. Learning Objectives • Students should be able to develop a “back of the envelope” feasibility study for a selected, simple project to include” • Gross Work Breakdown Structure • Order of Magnitude Quantity Estimates • Order of Magnitude Cost Estimates

5. RAT 02.1: • Take out a piece of paper, put your name on it, • Take 2-minutes to write: • … the three things you should be able to calculate for a “back of the envelope” estimate according to the previous slide. • Now hand it to the front of the room in 30 seconds, starting now.

6. Some Examples of Local Projects • Renovation of Ross Street (good starter) • PS&E for a new CE Building (good example) • Cost and Revenue projection for WERC Parking Garage (good example) • Enhanced Parking and Access to the Main Campus (too complex)

7. Ross Street:Project Development Plan • Need – facility for opposing traffic. • At least two wide lanes for busses to pass each other. • Mix of other traffic – emergency vehicles?, Access to parking lots? Traffic circulation? • Local traffic is NOT a consideration.

8. In Class Exercise • What tasks (work break-down structure) are required to complete the job? • Write down list as individuals • As pairs refine the lists • As groups of four refine lists • Report results.

9. As IndividualsEstimate the following • Construction quantities: • Demolition of existing pavement (30-ft by 1,500-ft, for a first SWAG) • Repair of utilities (FTE-Years) • Sub base (average 4-ft deep) • Base course (average 1-ft deep) • Pavement with curb and gutter (average ¾ -ft deep)

10. Estimate the following: • Direct Construction Costs (labor & materials): • Demolition of existing pavement • Repair of utilities • Sub base • Base course • Pavement with curb and gutter • Fringe Benefit Costs (15% of Direct) • Indirect Costs (150% of Direct) • Profit and Contingency (It depends upon risk factors but let’s say 10-25%)

11. Rough Cost Calculation Example Warning: I asked a slightly more complex problem on the Final Exam and 30% of the class missed it. Since I asked about the same problem on all three exams, not being able to answer it cost some students a letter grade.

12. Basic Assumptions • TAMU Owns the property. • There are no significant environmental issues. • Construction will occur over the summer; so, traffic will not be a problem. • TAMU will pay cash for the work.

13. Project Development Process: General Steps • Needs Assessment • (Re)Definition & Scope • Identify Stake Holders • Supporters and Blockers • Conceptual Design • Generation of Alternatives • Physical Assessment – Research Required? • Fiscal Assessment – Timing? • Political Assessment – Climate?

14. … Continued • Development of “Pathfinders” or Pilot Studies • Based upon research needed. • Based upon gaining political support • Based upon the fiscal situation • Development of Prototype(s) or Final Design(s)

15. Additional Parking/Access Project - Needs • All would generally agree that the campus is congested. • What is really needed? • More Parking – structures and/or lots? • More busses? Jitneys? Trolley? • Organized “kiss and ride”? • Car and Vanpools? • Internal circulation plan?

16. Additional Parking/AccessProject – Business Plan • Business Plan • Revenue Stream? • Bus Fees • Parking Fees • Other • Initial Cost? • Construction • Other – Design, ?? • Operation and Maintenance (O&M) Cost?

17. Additional Parking/Access Project – Engineering • Select Final Plan (list of selected alternative phases or construction projects) • Prepare PS&E (plans, specifications, and estimates) • Etc.

18. Basic Assumptions • TAMU Enjoys Sovereign Immunity and can do as it pleases – state law. • TAMU owns the land. • There are no significant environmental issues. • General Revenue can not be used to provide for parking – state law. • TAMU can not “go into debt” – state law.

19. New CE BuildingProject Development Plan • Need – Modern Classroom and Project Space. • Classrooms • Traditional • TAL – ACL – ILC Type space • Project Space • Growth Areas • Traditional Laboratories • High Tech • Offices • Departmental • Faculty and Other Instructors • Student Organizations

20. CE BuildingBusiness Plan • How many sq-ft of laboratory, office, and classroom space? • What will enhance our reputation? • Cash Flow Considerations: • What will big donors support? • What will the State support? • Location Considerations

21. Back-of-the-Envelope Estimate • Determine Sq-ft • Traditional Classrooms • High Tech Classrooms • Traditional & Computer Labs • Offices – Individual and Departmental • Price out each using Means Manual and other sources of Info

22. Cont’d. • Sum Direct Costs • Building • Equipment • Determine A/E Fees • Add TAMU Indirects • Add Profit and Contingency • Etc.

23. CE BuildingBasic Assumptions • We Own the Land • There are no significant environmental issues. • We can use a mix of State and Private Funds • TAMU can not “go into debt” – state law
