Introduction
This report outlines the development and implementation of the Recovery Schedule for the ABC Tower Construction Project. Due to unforeseen delays in key activities, the project has fallen behind its original baseline schedule. The purpose of the recovery schedule is to mitigate the delays, restore progress to the critical path, and ensure that the project is completed within the contractual deadline. The recovery schedule has been developed through a detailed analysis of the current status, identification of the delay causes, and adoption of strategies to expedite work.
1. Project Status and Reason for Recovery Schedule
The project is currently behind schedule due to several delay events that have impacted critical path activities. As of August 1, 2024, the project has slipped by 45 days, and without corrective measures, the contractually obligated completion date of December 31, 2024, will be at risk.
A. Key Delay Events
- Foundation Work Delays: Unforeseen site conditions and extended excavation periods caused a 20-day delay in foundation completion.
- Supply Chain Disruptions: Late delivery of steel for the superstructure resulted in a 15-day delay in the frame erection process.
- Adverse Weather: Heavy rainfall in June caused a 10-day delay in exterior façade work, impacting the building enclosure milestone.
B. Current Project Status
- Baseline Schedule Completion Date: December 31, 2024.
- Current Projected Completion Date: February 14, 2025.
- Days Behind Schedule: 45 days.
- Critical Path Impacted: The delays primarily impacted the superstructure and building enclosure phases, pushing back subsequent interior fit-out and commissioning activities.
2. Recovery Plan Objectives
The objective of the recovery schedule is to regain the lost 45 days and bring the project back on track to meet the original contract completion date of December 31, 2024. This will be achieved through the following strategies:
- Acceleration of Critical Path Activities.
- Re-sequencing of Non-Critical Activities to create additional float.
- Utilizing Additional Resources such as labor, equipment, and overtime.
- Concurrent Execution of Tasks where possible.
3. Key Recovery Strategies
A. Acceleration of Superstructure Construction
The delay in superstructure construction due to late steel deliveries can be mitigated by increasing labor and equipment resources. To accelerate progress:
- Double shifts will be introduced for steel erection work.
- Additional cranes will be deployed to handle multiple areas simultaneously.
- Overtime will be authorized for steelworkers to make up for lost time.
- Expected Time Recovery: 10 days.
B. Parallel Execution of Façade and Interior Work
To compensate for the weather-related delay to the exterior façade, certain interior fit-out tasks (e.g., MEP rough-in, drywall installation) will commence prior to full façade completion. The enclosure will still be completed in stages, with interior work beginning in enclosed areas.
- Expected Time Recovery: 15 days.
C. Re-sequencing of Non-Critical Activities
Non-critical activities with float will be re-sequenced to avoid further impact on critical path activities. For example, landscaping and final external works will be deferred to later phases, allowing resources to focus on critical path activities.
- Expected Time Recovery: 5 days.
D. Mobilization of Additional Resources
Additional resources (labor and equipment) will be mobilized to expedite MEP installation and interior finishes. Subcontractors will be instructed to bring in additional crews, and certain tasks will be performed in parallel to others.
- Expected Time Recovery: 8 days.
E. Weekend and Overtime Work
To accelerate all remaining activities on the critical path, weekend work and extended daily shifts will be implemented. Labor will be increased for all interior finishes and MEP installations, especially during the commissioning phase.
- Expected Time Recovery: 7 days.
4. Recovery Schedule Analysis
Using the Critical Path Method (CPM), the recovery schedule was developed by reanalyzing the current project schedule, adjusting durations, and incorporating the planned recovery measures. The recovery schedule has been implemented in Primavera P6 and reflects the following changes:
A. Revised Critical Path
The revised critical path has been shortened through the aforementioned acceleration measures. The activities on the revised critical path now include:
- Completion of the superstructure.
- Façade and building enclosure.
- Interior MEP installations and finishes.
- Final testing and commissioning.
B. Revised Milestones
The following milestones have been revised to reflect the recovery actions:
- Superstructure Completion: Revised from August 31, 2024, to August 21, 2024.
- Building Enclosure: Revised from October 31, 2024, to October 20, 2024.
- MEP Rough-In Complete: Revised from November 30, 2024, to November 20, 2024.
- Substantial Completion: Revised from February 14, 2025, to December 31, 2024 (restored).
5. Key Assumptions and Constraints
Assumptions
- Availability of Additional Resources: The recovery schedule assumes that the required labor, equipment, and materials will be available as planned.
- Client Approvals: Timely approvals from the client for any design changes, materials, or inspections are expected.
- Weather Conditions: Normal weather conditions are assumed for the remaining duration of the project, with no further adverse weather delays.
Constraints
- Workforce Fatigue: Extended shifts and overtime may lead to workforce fatigue, potentially reducing productivity. This risk will be managed by rotating crews and ensuring proper breaks.
- Limited Site Access: Due to the downtown location, mobilizing additional resources will require careful logistical planning to avoid congestion.
6. Monitoring and Implementation of Recovery Schedule
The recovery schedule will be closely monitored through regular progress updates and meetings. Key measures for implementation include:
- Weekly Progress Reviews: Progress will be reviewed weekly with the project team to ensure that the recovery measures are being implemented effectively.
- Earned Value Analysis (EVA): EVA will be used to track performance and measure actual progress against the recovery schedule.
- Subcontractor Coordination: Coordination meetings with all subcontractors will be held to ensure that additional resources are mobilized as planned.
If any further delays are encountered, additional recovery measures will be explored, including increasing the pace of work in non-critical areas and introducing further re-sequencing strategies.
7. Potential Risks and Mitigation Measures
A. Resource Availability
- Risk: Shortages in labor or material availability could hinder the recovery schedule.
- Mitigation: Maintain close communication with suppliers and subcontractors to ensure availability. Plan for alternative suppliers if necessary.
B. Additional Costs
- Risk: The acceleration strategies may lead to additional costs, especially for overtime and extra resources.
- Mitigation: Costs will be tracked and managed through strict budget controls, and the client will be informed of any potential budget impacts.
C. Safety Concerns
- Risk: Working longer hours or increasing the pace of construction may lead to safety risks.
- Mitigation: Enhanced safety protocols will be enforced, and safety officers will be assigned to monitor worksite conditions closely.
8. Conclusion
The recovery schedule has been developed to restore the project to its original completion date of December 31, 2024. The strategies outlined in this report will accelerate critical path activities, re-sequence non-critical work, and mobilize additional resources. The project team is committed to implementing the recovery measures while ensuring safety, quality, and budget control.
Regular monitoring and adjustments will be made to ensure that the project remains on track. The recovery schedule provides a clear path forward to successfully complete the ABC Tower Construction Project within the contractual timeframe.
