Feasibility Studies Module 01.1 Revised: 8/21/2015

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

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

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.

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)

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.

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.

As Individuals Estimate 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)

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%)

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.

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.

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?

… 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)

Machiavelli on Change One should bear in mind that there is nothing more difficult to execute, nor more dubious of success, nor more dangerous to administer than to introduce a new system of things: for he who introduces it has all those who profit from the old system as his enemies and only lukewarm allies in those who might profit from the new.

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?

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

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

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.

New CE Building Project 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

CE Building Business 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

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

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

CE Building Basic 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

Assignment As Teams, by Monday at the start of class, make a first cut at the estimate and be prepared to discuss and ask questions in class. Then, as Teams refine your work and turn in a final estimate on Wednesday as Assignment #2

CE Building – Assignment? As Individuals make first cut at the costs and be prepared to explain. Turn In and Keep a copy. After Teams are formed. We will refine the estimates from your original work.
