Feasibility Studies

Module 01.1Revised: 04/19/23

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

Cost Item CostDirect Costs (Labor and Materials) $1,000,000Plus: Fringe Benefits @ 15% $1,150,000Plus: overhead @ 150% $2,875,000Plus: Profit @ 10% $3,162,500Total Charge for the work $3,162,500

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)

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/AccessProject – 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.
