Feasibility Studies
Module 01.1
Revised: 3/23/2016
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
Direct Costs (Labor and Materials)
Plus: Fringe Benefits @ 15%
Plus: overhead @ 150%
Plus: Profit @ 10%
Total Charge for the work
Cost
$1,000,000
$1,150,000
$2,875,000
$3,162,500
$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/Access
Project – Business Plan

Business Plan

Revenue Stream?




Initial Cost?



Bus Fees
Parking Fees
Other
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.
