Process of Estimating
Break the project into cost centers
Estimate the quantities required for the cost centers (e.g., cubic yards of earth, lineal feet of pipe, etc.)
Price cost the quantities (most take into consideration analysis of production rates based on resources available)
Calculate the total price of each cost center by multiplying the quantities by the unit price.
Break work into individual work packages
Calculate quantities for each work item (adjust for waste)
Select construct methods to be used
Assign resource group to be used (crew composition, equipment, subcontractors)
Estimate production rate
Calculate crew cost
Calculate total work item cost

San Antonio building cost = Canton building cost
San Antonio index Canton building index
$1,500,000 = Canton building cost
55.0 154.1
Canton building cost = 154.1 x $1,500,000
55.0
Canton building cost = $4,202,277
Using published cost data, compute the cost to construct a 6 story dormitory consisting of 90,000 SF.
Using rough order of magnitude (cost per SF) data:
(a) What is the cost of this dormitory in Philadelphia, San
Francisco, and Miami?
(b) What would the same project cost in 2000, 2010
and today?
(c) Write a brief narrative discussing your methodology used to compute the costs.
(d) Cite your sources
(e) All reports shall be typed.
