Construction schedule crashing is a project management technique used to shorten the project duration by adding resources or changing work methods. While it can help meet tight deadlines, it often leads to increased costs and resource strain. This article presents real-world examples illustrating the application of schedule crashing and its financial impacts.
Example 1: High-Rise Building Construction
In a high-rise building project, the contractor faced a delay due to late material deliveries. To meet the client’s deadline, the project team decided to crash the schedule by adding extra shifts and increasing labor hours. This approach resulted in a 15% increase in labor costs and a 10% rise in equipment expenses. Despite the additional costs, the project was completed on time, avoiding penalties.
Example 2: Infrastructure Development
An infrastructure project involving road construction experienced delays caused by unforeseen weather conditions. To accelerate progress, the project managers opted for schedule crashing by deploying additional machinery and extending working hours. The cost implications included a 20% increase in overall project expenses, primarily due to overtime pay and equipment rental fees. The decision enabled the project to be completed within the original deadline, but at a higher cost.
Cost Implications of Schedule Crashing
- Increased Labor Costs: Overtime and additional shifts raise expenses.
- Higher Equipment Expenses: Extended use and rental fees contribute to costs.
- Resource Strain: Additional resources may lead to inefficiencies.
- Potential Quality Risks: Rushed work can compromise standards.
