Construction Timeline Tracker — The Mukaab Engineering Milestones and Phase Progress

Construction Timeline Tracker

This dashboard tracks The Mukaab’s construction progress against the four-phase build sequence that determines when immersive experience technology can be installed and commissioned.

Phase 1: Substructure (2024-2027)

Key Data Points: The excavation removed enough earth to fill approximately 5,600 Olympic swimming pools. The New Murabba Development Company confirmed excavation completion in its August 2025 Falcon’s Creative Group partnership announcement.

Phase 2: Superstructure (2027-2028)

Key Data Points: The 1 million tonnes of structural steel will make The Mukaab the heaviest building in the world — approximately four times the weight of Bucharest’s Parliament building. For comparison, the Burj Khalifa used 31,400 tonnes.

Phase 3: Envelope and Interior (2028-2029)

Dependent on Phase 2 completion. This phase opens technology installation windows for venue-specific experience hardware.

Phase 4: Technology and Commissioning (2029-2030)

Dependent on Phase 3. This phase covers holographic dome display installation, spatial audio deployment, AI content system commissioning, and multi-sensory integration.

Project Status Notes

Engineering Scale Context

The Mukaab’s construction represents engineering challenges without direct precedent. To contextualize the data tracked in this dashboard, consider the following scale comparisons:

Structural Steel Volume — The 1 million tonnes of structural steel contracted for The Mukaab exceeds any single building in history by a substantial margin. The Burj Khalifa, the world’s tallest building at 828 meters, used approximately 31,400 tonnes of structural steel — meaning The Mukaab requires roughly 32 times the Burj Khalifa’s steel volume. The $1 billion steel contract represents approximately 2% of the total $50 billion New Murabba investment, but the steel’s fabrication, transportation, and erection timeline drives the overall construction schedule. Steel fabrication across multiple facilities worldwide must be coordinated with site-readiness at the al-Qirawan district location, with logistics handling approximately 27,000 tonnes of steel delivery per month to maintain the projected timeline.

Foundation Engineering — The 1,200 planned foundation piles, with over 1,000 already installed as of late 2024, support a building that is expected to become the heaviest in the world — approximately four times the weight of Romania’s Palace of the Parliament (currently the world’s heaviest building at approximately 4 billion kilograms). The foundation piles penetrate deep into Riyadh’s limestone bedrock, each pile designed to bear thousands of tonnes of structural load. The foundation system must accommodate not only static building weight but also dynamic loads from wind pressure (significant at 400 meters height), seismic activity (Riyadh sits in a low-seismicity zone, but design codes require conservative seismic resistance), and thermal expansion across the extreme temperature range experienced in central Saudi Arabia.

Excavation Volume — The 14 million cubic meters of earth removed during site excavation represents a volume sufficient to fill approximately 5,600 Olympic-sized swimming pools. At 86% completion as of October 2024, the excavation was approaching its target of approximately 16.3 million cubic meters. The excavation rate — processing roughly 200,000-300,000 cubic meters per week at peak operations — required a fleet of heavy equipment including excavators, dump trucks, and earth-moving equipment operating 24 hours per day. The excavated earth was either used for site grading elsewhere in the 19-square-kilometer New Murabba master plan or transported to approved disposal sites.

Construction Suspension Analysis

The January 2026 Reuters report of construction suspension beyond excavation and pilings placed The Mukaab within the broader context of Saudi Arabia’s Vision 2030 megaproject portfolio reassessment. Several factors contextualize this development:

Portfolio Prioritization — Saudi Arabia’s simultaneous development of multiple megaprojects (New Murabba, NEOM, Qiddiya, Red Sea, Amaala, Diriyah, and others) creates aggregate construction demand that strains both financial resources and contractor capacity. The portfolio reassessment reflects a strategic decision to sequence rather than parallelize all megaprojects — a pragmatic approach that prioritizes delivery quality over schedule speed. NEOM’s earlier scaling back from its original 170-kilometer linear city concept to a more focused development demonstrates this prioritization philosophy.

Market Conditions — Global construction material costs, particularly steel and specialized structural components, experienced significant inflation during 2023-2025. Oil price volatility, while ultimately supportive of Saudi government revenue, created periods of budget uncertainty that affected capital allocation decisions across the Public Investment Fund’s portfolio. The timing of the $1 billion steel contract suggests that material procurement continued despite the broader suspension, indicating that foundational supply chain commitments remained active.

MIPIM 2026 Participation — New Murabba Development Company’s active participation in MIPIM 2026 in Cannes, France (March 2026) — one of the world’s most important real estate conferences — signals continued project commitment and commercial positioning. Projects approaching cancellation do not typically invest in international real estate marketing. The MIPIM showcase highlighted Riyadh’s “future-ready downtown vision,” positioning New Murabba as a premier mixed-use development attracting international tenants, investors, and hospitality operators.

Technology Installation Dependencies

Each construction phase creates specific windows for immersive technology infrastructure installation:

Phase 1 Dependencies (Substructure): Conduit routing for the building’s content distribution network — estimated at 5,000-20,000 kilometers of fiber-optic cable — must be planned during substructure design. Conduit installation during foundation and basement construction is 5-10x less expensive than retrofit installation after structural completion. Power distribution infrastructure for the dome’s estimated 75-600 MW display power requirement must be routed through basement-level electrical rooms connected to the city grid and backup generation systems.

Phase 2 Dependencies (Superstructure): The cube exoskeleton’s steel framework includes mounting points for dome display panels, spatial audio speaker arrays, environmental system ductwork, and sensor networks. These mounting specifications require technology vendor selection during Phase 2 — before the steel framework is fabricated — to ensure that structural members include the correct attachment points, cable penetrations, and load-bearing provisions. The dome support structure, in particular, must be engineered for the specific weight and mounting geometry of the selected display technology (LED panels at 10-15 kg/m², projection screens at 1-3 kg/m², or hybrid configurations).

Phase 3 Dependencies (Envelope and Interior): Interior build-out creates venue-specific technology installation windows. Each of the 80+ entertainment venues requires custom technology infrastructure — display controllers, amplifiers, environmental system actuators, haptic floor platforms, lighting rigs — installed during the interior fit-out phase. The 9,000 hotel rooms require dome-facing electrochromic glass installation, in-room holographic display systems, and integration with the building’s IoT network. The spiral tower’s observation platforms require structural glass, smart glass panels, and holographic overlay systems installed before the tower’s interior completion.

Phase 4 Dependencies (Technology and Commissioning): The final phase integrates all technology systems into a functioning whole. The holographic dome display system, AI content generation cluster, spatial audio array, environmental systems, crowd management sensors, and biometric identification network must be commissioned as an integrated system — a process estimated at 12-18 months for a building of this complexity. Commissioning includes audio-visual synchronization calibration (within 45 milliseconds across all zones), scent zone isolation verification, display color and brightness calibration across potentially millions of LED tiles, and end-to-end stress testing under simulated peak visitor loads.

Comparison with Global Megaproject Timelines

The Mukaab’s projected timeline of approximately 6-7 years from construction commencement to first-phase completion is aggressive but not unprecedented for supertall buildings. However, The Mukaab’s unique characteristics — cube geometry rather than tower form, massive interior atrium requiring dome technology, and 2 million square meters of interior fit-out including 80+ custom entertainment venues — create construction complexity beyond any conventional supertall comparison. The January 2026 suspension introduces timeline uncertainty that this dashboard will track as new information becomes available.

Construction Scale in Global Context

The Mukaab’s construction represents an undertaking without precedent in building history. To contextualize the construction tracker data:

Excavation Volume: The 14 million cubic meters of earth moved for excavation exceeds the volume excavated for the Panama Canal’s third set of locks (approximately 50 million cubic meters over a multi-year period). The Mukaab’s excavation reached 86% completion by October 2024, demonstrating the mobilization capacity of Saudi Arabia’s construction sector — supported by the $196 billion in Vision 2030 tourism contracts that have scaled the kingdom’s construction workforce and equipment base.

Structural Steel: The $1 billion structural steel contract covering 1 million tonnes represents approximately 1% of global annual structural steel production. For comparison, the Burj Khalifa required approximately 39,000 tonnes of rebar and 45,000 tonnes of structural steel. The Mukaab’s steel requirement — 25 times the Burj Khalifa’s — reflects the cube geometry that encloses maximum volume within minimum surface area, requiring massive structural framing to span 400-meter clear distances.

Foundation Engineering: The 1,200 planned foundation piles, of which 1,000+ were installed by late 2024, must support the expected heaviest building in the world — approximately 4 times the weight of Bucharest’s Palace of Parliament (currently the world’s heaviest building at approximately 4.1 million tonnes). The pile design must transfer building loads through Riyadh’s geological strata to bedrock, with each pile engineered for the enormous point loads that a 400-meter cube structure creates.

Weight Classification: The Mukaab is expected to become the heaviest building ever constructed. The structural engineering challenge is not just supporting the building’s dead weight but resisting the wind loads that act on a 400-meter-wide, 400-meter-tall facade — creating overturning moments that the foundation system must counteract. The cube geometry — presenting 160,000 square meter faces to wind — creates aerodynamic forces that AtkinsRealis must engineer for in the structural design.

Technology Installation Windows

The construction tracker monitors milestones that determine technology installation windows. Display technology (LED panels, micro-LED, holographic film) cannot be installed until dome structural framing is complete and the interior environment is weather-sealed. Spatial audio speakers mount to completed interior surfaces, requiring finish work completion in each zone. Smart glass panels install during facade completion, coordinated with Najdi architectural cladding installation. Floor-level haptic systems install during finish flooring, requiring structural floor completion and utility routing. Each technology system’s installation window is determined by construction milestones that the tracker monitors — creating a critical path from structural completion through technology installation to operational readiness.
