Hospital Project Delay: Monsoon, MEP Mobilization and a Façade Change
A 200-bed hospital project has an 18-month contract duration. The critical path runs through piling, pile caps, superstructure, MEP rough-in, façade, and interior finishes. At the end of month 7, the contractor reports: superstructure is 6 weeks behind because of an extended monsoon; the MEP subcontractor mobilized 3 weeks late; and the client has changed the façade from precast concrete to unitized curtain wall, adding 4 weeks to procurement lead time. The contract has liquidated damages at 0.5% of contract value per week. The contractor proposes to crash the superstructure and MEP activities by adding a second shift. The client wants the original completion date maintained. The project manager must advise on schedule impact, recovery options, and contractual entitlement.
1. Analyze the delay events and determine which are critical-path delays and which are non-critical. What is the likely overall delay if no action is taken?

The superstructure delay is on the critical path, so 6 weeks passes directly to completion. The MEP mobilization delay may not be fully critical: MEP rough-in follows superstructure, and if the MEP subcontractor has, say, 2 weeks of float before rough-in must start, then only 1 week of the 3-week delay affects completion. The façade change is critical because unitized curtain wall procurement follows MEP rough-in and precedes interior finishes. The 4-week procurement lead-time increase adds 4 weeks. If the MEP delay has 2 weeks float, the likely overall delay is 6 + 1 + 4 = 11 weeks. If MEP has no float, it is 13 weeks. The project manager should not simply add all three numbers; they must check the programme logic and float. The liquidated damages exposure at 0.5% per week is significant, so the analysis should be documented with a time-impact analysis showing each event separately.
2. Evaluate the contractor’s second-shift proposal as a recovery measure. What activities would you crash first, and what cost and quality risks would you flag?

A second shift is not equally effective on all activities. Crashing superstructure is risky because concrete curing and formwork cycle times are governed by physics, not labour. Adding a night shift can increase supervision problems, poor vibration control, and cold-joint risks. It may recover only 1–2 weeks, not 6. MEP rough-in and interior finishes are more labour-intensive and can benefit from a second shift, but coordination and inspection delays must be addressed. The best sequence is: first, crash MEP rough-in and façade installation using additional crews in parallel zones; second, accelerate interior finishes with prefabricated bathroom pods and modular headwalls; third, only then consider limited night work on superstructure where curing allows. Flag risks: overtime cost premium, fatigue and safety, reduced inspection coverage, and rework from poor workmanship. The contractor should submit a revised method statement and a cost-loaded recovery schedule before approval.
3. Advise the client on contractual entitlement for the façade change and monsoon delay, and recommend a documented recovery plan.
Read the worked answer
The façade change is a client-instructed variation, so the contractor is entitled to an extension of time for the 4-week procurement impact and to the direct cost of the change. The monsoon delay needs closer analysis: in Indian contracts, normal monsoon is often a foreseeable risk and may not be force majeure unless rainfall exceeded the contractual threshold or the tender documents promised a dry-season window. If the monsoon was exceptional and the contractor notified correctly, an extension may be due; otherwise, the 6 weeks may be at the contractor’s risk. The MEP subcontractor’s late mobilization is the contractor’s responsibility. Recommended recovery plan: issue a formal variation for the façade, instruct the contractor to place the unitized curtain wall order immediately, re-sequence interior finishes to start in completed zones, and hold weekly delay-review meetings. All notices and schedules should be in writing. The client should reserve liquidated damages only for delays that are not excused.
