Implementation Roadmap
The integrated programme Gantt, the critical milestones, the critical dependencies and sequencing and the work-package schedule and critical path across the phased build.
The development programme is structured into four sequenced phases
over approximately 48 months, designed so that revenue-generating
operations begin in Phase 1 and build steadily as later phases are
commissioned. The integrated Gantt chart below sets out the critical
milestones, timelines and dependencies.
11.1 Integrated Programme Gantt
11.2 Critical Milestones
| Milestone | Target month | Dependency | Significance |
|---|---|---|---|
| Financial close | Month 9 | Approvals + funding | Unlocks construction |
| Runway & apron complete | Month 18 | Earthworks, civils | Enables flight operations |
| Passenger terminal open | Month 21 | Terminal build, systems | First passenger revenue |
| Cargo precinct live | Month 30 | Warehousing, customs | Cargo & cold-chain revenue |
| FBO / MRO operational | Month 30 | Hangars, certification | Premium services revenue |
| Aerotropolis Phase 1 | Month 42 | Anchor tenants | Property income at scale |
| Steady-state operations | Month 48 | All phases ramped | Full cash generation |
11.3 Critical Dependencies & Sequencing
The programme’s critical path runs through regulatory approvals and
financial close (Phase 0), the runway and terminal (Phase 1), and
anchor-tenant commitments (Phases 2 and 3). Key dependencies are managed
as follows:
- Approvals before capital: environmental and
aviation approvals are secured before major civil works commence,
de-risking the largest capital tranche. - Revenue before completion: the passenger
terminal opens in Month 21, generating revenue while later phases are
still under construction. - Anchors before speculative build: cargo and
property development proceeds on the back of committed anchor tenancy,
limiting vacancy risk. - Parallel work-streams: operations on-boarding
and route development run concurrently with construction to compress
time-to-revenue.
11.4 Work-Package Schedule & Critical Path
The table below decomposes the programme into its principal work
packages, showing duration, logical predecessors and schedule float.
Packages with zero float lie on the critical path and receive priority
management attention, contingency and reporting.
| Work package | Months | Duration | Predecessor | Float |
|---|---|---|---|---|
| WP1 — Approvals & financial close | 0–9 | 9 mo | — | 0 (critical) |
| WP2 — Bulk earthworks & services | 6–14 | 8 mo | WP1 (part) | 0 (critical) |
| WP3 — Runway, taxiway & apron | 10–18 | 8 mo | WP2 | 0 (critical) |
| WP4 — Passenger terminal & systems | 11–21 | 10 mo | WP2 | 0 (critical) |
| WP5 — Airfield certification | 18–21 | 3 mo | WP3 | 1 mo |
| WP6 — Cargo precinct & cold chain | 20–30 | 10 mo | WP3, WP4 | 2 mo |
| WP7 — FBO / MRO hangars | 20–30 | 10 mo | WP3 | 3 mo |
| WP8 — Aerotropolis Phase 1 (property) | 28–42 | 14 mo | WP4, anchors | 4 mo |
| WP9 — Ramp-up to steady state | 21–48 | 27 mo | WP4 onward | n/a (continuous) |
The critical path runs WP1 → WP2 → WP3/WP4 to first passenger
revenue in Month 21. A ~10% construction contingency and float on
non-critical packages provide schedule resilience; gated capital release
ties each tranche to completion of its predecessor
package.
