FEATURED Q&A (FAQ)
Q1.What is Change order disruptions and indirect delay overhead in commercial construction?
A project management study measuring how change orders generate indirect costs through schedule slippage, crew disruption, and extended site overhead.
Q2.How is it calculated?
Direct material and labor change parameters are loaded with fixed daily site overhead and labor inefficiency multipliers. Formula: True Change Order Cost = Direct Materials & Labor + (Schedule Extension Days * Daily Fixed Site Overhead) + Labor Inefficiency Cost.
Q3.Why does it matter / What are the benefits?
Bidding change orders solely on direct costs ignores schedule extensions. If a change extends a project by 8 days, the contractor absorbs 8 days of fixed site overhead, eroding profit.
Problem
An electrical subcontractor signed a contract change order based on material costs but suffered a net margin loss due to an 8-day project delay and crew disruption.
Input set
- Base contract: $250,000, direct change order value: $14,500
- Schedule extension: 8 days, daily site burn rate: $1,850/day
- Target margin floor: 15%
Calculation result
While the change order appeared profitable on a direct-cost basis, the 8-day delay burn rate caused a 4.2% erosion in the overall project net margin.
Suggested action
Include fixed daily site overhead and mobilization fees as separate items in all change order proposals.
Methodology note
Construction scheduling delay analysis (Eichleay Formula variations) applied to indirect cost distribution.
