Note: When Cost Estimating you need to put out an "APB" to get valid cost estimates.
1. Direct Labor Expense
2. Non-Direct Labor Expense
3. Overhead Expense
4. General and Administrative (G&A) Expense
5. Profit

A Cost Estimating Method technique for estimating the duration or cost of an activity or projecting using HISTORICAL DATA from a similar activity is _____.
Analogous Estimating
IE: house next door is similar except 1 car garage, we want 2 car garage.
2. Some are Derived from CONSTRAINTS.
A Cost Estimating Method technique in which a ALGORITHM is used to calculate costs or duration base on historical data and project parameters is _____.
Parametric Estimating
ie - We want 2000sf home, Builder first 1800sf at $90sf, remainder at $60sf
A Cost Estimating Method technique in which estimating project duration or cost by AGGREGATING the estimates of the lower level components of the Work Breakdown Structure (WBS) is ______.
Bottom Up (Grassroots) Estimating
ie - Need $x for foundation, $x for structure, $x for appliances
