Construction & Contracting
Construction & contracting: progress payment/retainage/POC, WBS, job costing, subcontractor, budget, OHS.
Challenges
- Site costs vanish into overhead, so project profit is invisible.
- Take-off and actual work are not compared, so budget overrun is noticed late.
- The progress billing file is built in Excel and keyed into accounting by hand.
- Subcontractor progress and payment do not sit together, so overpayment is a risk.
Workflows
From take-off to progress billing
- The site is opened and work items are entered with take-off and unit price.
- The completed-work percentage is posted each period.
- The progress bill is generated from completed work and linked to an invoice.
Subcontractors and consumption
- The subcontract is tied to a work item.
- Material consumption and machine hours are posted to the site.
- A subcontractor's progress bill cannot exceed the completion percentage.
