The complete record of the engineering work behind the Multi-Modal Corridors platform — engineering memos describing the system, the seven Australian provisional patents, reference documents, and the evidence base. Pre-feasibility grade. Honest numbers. Detailed engineering study required before any binding use.
All MMC engineering output in one place — memos describing the platform, patents protecting the architectural primitives, reference documents, and external evidence.
Pre-feasibility engineering memos on the MMC system. All 11 memos in the series are now published. Each memo is a companion to one or more patents in the MMC Patent Family, or to a specific platform component (megafactory, foundations, viaduct, transmission, station architecture). To request advance access for partner discussion, contact the team.
The parallel-line manufacturing principle, Hub-and-Spoke deployment, and a worked example: MMC-TB single-leg transmission tower over 500 km. 110,000 modules, 11 designs, dedicated steel fabrication line for cutter heads. Companion to Patent 7.
Worked tension calculations for the MMC transmission tower family — 132 kV through ±1100 kV UHVDC. Three deployment options on a single SKU. Companion to Patents 5 and 6.
The Anchor Tension System (ATS) caisson — drilled and grouted foundations across the MMC platform. Single integrated drilling-and-installation pass. Companion to Patents 1, 2, 3, 4.
Direct technical comparison: SBC Phase 0 multimodal viaduct vs the High Speed Rail Authority's tunnel-based passenger rail. Cost, schedule, capability, deliverability.
The single-leg single-deck MMC-VC viaduct deployed for Phase 0-2 — ridge route through the Watagans. Engineering case for a 15-minute Newcastle-to-Sydney maglev journey.
Pylon geometry, cap beam and girder design, HVDC arm loading, longitudinal wire-rope continuity system. Module catalogues. Companion to Patents 4 and 5.
The continental rollout configuration — five integrated service levels (freight, aqueduct, services, hyperloop reservation, maglev) on a dual-leg viaduct at 50m to top deck.
An apples-to-apples comparison of maglev vs high-speed rail, both deployed on the MMC viaduct platform — and why the continental Australian case is decisively maglev geography.
UHVDC trunk for bulk transfer. VSC HVDC backbone for solar collection. MVDC for towns and the multimodal viaduct. Three voltage levels in parallel — uses only commercially proven technology, with upgrade paths as DC-DC converter research matures.
The unifying principle: stopping trains use side tracks; main alignments run corridor speed uninterrupted. Applied at two scales — freight ramps to ground-level terminals + maglev side guideways on the 4-track-capable upper deck. Built on the two-legged MMC pylon (embodiment of the company logo) at 25 m spacing. Worked example: Newcastle–Sydney 27 min with 2 stops (80% faster than current). Daily capacity ~100-145 movements/direction/day. Switch speed identified as the engineering scaling variable for corridor experts.
The bearing-only interface between the sacrificial cutter head and the lead caisson ring. Sets out AS 3600 bearing capacity (FS 2.9), the hybrid hard-faced thrust pad system with debris sleeve, and the dual-purpose Anchor receptacle. Bidirectional WOB control via drill pipe lift.
The castellated dog-clutch joints between adjacent caisson rings. Skin-friction-breaking torque transmission, with four engineering mitigations for concrete-on-concrete cyclic shear: radiused roots, elastomeric shims, zero-draft faces, closed-loop confinement.
The economic case for the disposable cutter head. ~$3K MMC Hub production vs ~$10K bespoke (75-85% saving). Single standardised design across the corridor with geological adaptation via insert replacement rates. Net Phase 0 saving ~$2.6-7.4B from single-pass methodology.
The Hub-and-Spoke production architecture for ~2.1 million precast caisson rings across the Phase 0 corridor. Two ring variants (standard and lead), ~$390 mid-range unit cost, ~$1 billion aggregate Phase 0 caisson ring programme. Companion to Patents 1 and 7.

The four canonical SBC programme documents — the strategic and economic substrate that frames the engineering work in the memos.
External technical references — government planning, industry studies, peer-reviewed research — that the engineering memos cite or refer to.
Technical articles, conference papers, interviews, and engineering coverage.
The MMC memos are internal working documents made public. The numbers are pre-feasibility grade — within ±20–30% of detailed design values, suitable for programme planning and investment discussion, but not for binding engineering commitments. Each memo flags its own caveats and identifies the engineering questions that require resolution at detailed design stage.
The MMC programme is built on the principle that honest numbers at pre-feasibility are more valuable than polished numbers at final design — because they allow the right decisions to be made earlier. Every figure in these memos is traceable to an assumption, and every assumption is stated. If you disagree with an assumption, the memo tells you exactly where to push back.
