What is the maximum OSP cost variance generally accepted?

The generally accepted maximum OSP cost variance is 10%. This standard is widely recognized in project management as it helps maintain fiscal responsibility and ensures that a project remains within manageable financial boundaries. A 10% variance serves as a threshold that indicates the project is still relatively under control, allowing for minor shifts in pricing due to unforeseen factors such as material costs or labor rates without significantly jeopardizing the overall budget.

By adopting this 10% variance, project designers and stakeholders can adequately plan for contingencies while also facilitating adjustments that align with the project’s financial sustainability. If the variance were to exceed this percentage, it might signal deeper issues with project oversight or assumptions made during the initial budgeting phase, possibly necessitating more significant corrective actions. This level of variance strikes a balance between maintaining flexibility and ensuring accountability in financial management within Outside Plant projects.
