Indirect Costs and Profit Applications
Example 1: Calculating General Conditions from a Schedule
For a highly accurate bid, an estimator must use the preliminary project schedule to calculate time-based General Conditions (Project Overhead).
A commercial building project is scheduled to last exactly .
-
Supervision: One full-time Project Manager at a burdened salary of \12,000/\text$9,000/\text$.
-
Facilities: The site office trailer rental (including utilities and internet) is \1,500/\text$.
-
Equipment: A tower crane is needed on-site for only at a rental cost of \8,000/\text$.
-
Fixed Fees: The municipal building permit is a one-time fixed fee costing \15,000$.
Calculate the total detailed Project Overhead (General Conditions) cost.

A general contractor calculates the following raw direct costs for a small commercial building project: Materials (\500,000$300,000$100,000$).
The contractor's standard markup policies apply for Project Overhead, for General (Home Office) Overhead. Following a risk review, they add a Contingency for unforeseen site conditions based on the combined direct and overhead costs. Finally, the contractor desires an Profit margin on the entire estimated cost.
Determine the final bid price to submit to the owner.

A contractor calculates the total estimated cost (Direct + Indirect + Contingency) of a project to be \800,00015%$ Profit Margin on the final contract price to meet its financial goals.
Calculate the required final bid price to achieve a margin, and determine the equivalent Markup percentage applied to the cost.
Step-by-Step Solution
0 of 5 Steps Completed- Calculating General Conditions (Project Overhead) accurately requires aligning site support costs with the expected project schedule duration, rather than applying a flat percentage to direct costs.
- Markups must be applied sequentially; profit is typically a margin on the total estimated cost, which includes the contingency amount.
- Estimators must clearly distinguish between Margin (percentage of revenue) and Markup (percentage of cost). A desired margin of always requires a markup greater than .
