SCOPE OF WORK — 6 PACKAGES

SERVICE SLA LEVELS — REQUESTED vs COMMITTED

⚠ OPEN GAPS → carrier escalation
① VNPT letter states no uptime % and no MTTR — request a written 99.99%+ / MTTR ≤4 h addendum.
② Viettel 99.95% vs 99.999% requested = 1 nine (≈4.4 h vs ≈26 s unavailable per year).
③ Single-carrier RTD misses ≤20 ms; active-active dual-carrier at 21 ms is the practical floor until ALC RFS.
④ MRC/NRC deferred by both carriers to 2027-Q1 — blocks OPEX lock-in in the FS financial model.

Diversity study — why two media, not two cables
▸ Route A · ngầm (underground) — HDPE 4-way duct bank, 1.2 m cover, handhole @250 m along Collector C-15.
   + typhoon / Cat-12 wind immune, no pole-owner dependency   − excavation strike risk, MTTR 8-12 h, CAPEX ~3×
▸ Route B · treo (aerial ADSS) — co-hung on the 22kV pole line along C-20, ≥4.5 m road clearance.
   + MTTR 2-4 h, fast to deploy, low CAPEX   − wind/typhoon & pole-work exposure, shares the 22kV corridor
▸ Failure independence — taps 5.34 km apart, MMRs 2.40 km apart, no shared duct, pole, handhole or ops house ⇒ matches the Viettel “two separate physical corridors” commitment and VNPT “aerial + underground, two route directions”.
▸ N-1 result — either single entry carries the full campus load; a Route A cut switches to Route B within the ≤50 ms carrier commitment.

ZONE BRANCH SCHEDULE

▸ Ring follows the GT road reserve — Arterial A-5 / A-8 crossed with Collector C-15 and C-19+C-20, so the duct stays inside land already reserved for roads (no extra acquisition).
▸ Each zone tees off the nearest ring handhole; traffic reaches both MMRs around the loop, so one duct break never isolates a zone.
▸ FZ-4 AI DC is the only dual-fed load — feed A and feed B leave the ring ≥1.5 km apart (357 m / 774 m branch ducts) and land on different MMRs and different carriers.

The map starts clean. Press ZONE CLEAN at any time to return to that state, then render 1A → 1B → 2 → 3 in order. Phase 1 is now split into its two delivery tranches, because 1A (2026) and 1B (2027) start on different gates — see 9-2 for the month-by-month build-out.

LEGEND

Month-by-month simulation of the two 2026–2027 tranches. Land is released along the SR-6 axis (bearing 293.4°) from the La Sơn interchange inward, in equal-area steps: 1A in 4 steps (Sep–Dec 2026) and 1B in 12 steps (Jan–Dec 2027).

MILESTONES IN THIS WINDOW

Tranches 1A and 1B share one dossier (Dossier 1): the split is by schedule and funding source, not by plan. The number of 1/2,000 zoning dossiers is therefore three.

START GATES

M6 is the single point where this delivery axis meets the power axis (grid Phase 1 COD). Delivery tranches (1A/1B/2/3) and grid phases (P1 2027 / P2 2032) are different axes — do not conflate them.

Land-use balance of the five functional sub-zones, from the establishment scheme drawing (Đề án — Landscape and spatial organisation, 12 Jul 2026). The 12-zone presentation FZ-1–FZ-12 used in earlier reports has been superseded by this structure.

Reconciliation note — the establishment scheme explanatory report states PK-1 as 272.07 ha (drawing: 272.87 ha), PK-5 as 21.03% (recomputed from area: 21.82%) and a total of 1,081.89 ha (drawing: 1,081.00 ha). This panel follows the drawing; alignment before submission is recommended.

The tranche geometry rendered in 9-1 and 9-2 comes from boundary traces recorded on 11 Sep 2026 against the surveyed site boundary. Those traced areas do not yet agree with the indicative bands published in the phasing report (9-3). Both are shown here; neither has been silently overridden. Reconciliation is required before submission.

TERRAIN AT THE DIGITISED VERTICES

Classes are sampled at the digitised vertices only — they describe the ring outline, not the area inside it. Source: the four coordinate-record exports of 11 Sep 2026 (DEM VN-2000 / TM-3 107°).

TRACE QUALITY

■ All four rings close (gap 2.6–13.4 m) and are simple — no self-intersection.
■ Vertices sit on the surveyed boundary to within 6.6 m (mean 1–4 m); every ring is clipped to it, so 0.00 ha falls outside.
■ Mutual overlap is 0.92 ha (1B ∩ 3) out of 1,053.50 ha.
■ The union leaves 25.49 ha (2.4%) of the site uncovered — edge slivers between rings.

INDICATIVE — not an approved boundary.
No approved boundary vector exists for PK-1–PK-5. The Phase 1 boundary awaits milestone M1 (City People's Committee decision) and the Phase 2 and 3 boundaries are fixed in each phase's own 1/2,000 dossier — HEART-A-QHPK-RPT-001 Rev.C, Annex 3, items 1, 6 and 7.

The site boundary is the canonical 206-point surveyed ring (Decision 756/QĐ-UBND, 1,078.98 ha computed), replacing the 74-point simplification used previously. PK sub-zone areas reproduce the establishment scheme Table 1 figures; the GT road land is drawn as the residual corridor network between the sub-zones. Tranche rings 1A/1B/2/3 are surveyed-boundary traces of 11 Sep 2026, clipped to the same ring.
Allocation rule — isolation green (CXCL): buffer along the 500 kV line grown to the target area; PK-1–PK-5: capacity-constrained additively weighted Voronoi over surveyed anchors.
