- Buyer: EPFL - Domaine des Achats

## From the tank inventory to a complete offer, lot by lot

Ninety-four pages, a 13-sheet workbook and a tank inventory, and the requirement that excludes you sits in one cell of the workbook. We call it the annex blind spot.

### Five lots, twenty tanks, two units

Quantities sit in the workbook, tanks in the inventory, rules in the specification. Ziva puts each lot in one row with its source and flags what does not match.

Screenshot: The Lots sheet in Ziva: quantity, unit and tanks per lot of the EPFL tender, each with its source.

### A knock-out that only one file mentions

Sixteen requirements are eliminatory. Ziva lists all of them with the document that asks, including read access for EPFL’s maintenance systems, which only the workbook requires.

Screenshot: The Requirements sheet in Ziva: requirements A to P of the EPFL tender, all eliminatory, with the proof each needs.

### The delivery plan comes from the inventory

Ziva turns the 2025 fills of each tank into fills a year with live formulas. Your fill rate and density stay yellow until your team confirms them.

Screenshot: The delivery plan in Ziva: the 14 tanks of lot 1 ranked by 2025 fills, with fills a year computed from the inventory.

## Ziva’s work on this tender, redrawn

### Ziva reads the whole EPFL dossier: four open lots, 20 tanks and 3.4 million Nm³ of nitrogen a year.

Source: Redrawn from the Ziva Project “Gaz de laboratoires 2026 | SIMAP 43773” with the 10 public tender documents, 15 November 2026. Circle area by yearly quantity (Annexe 7, sheets 3.1 to 3.5); tanks from the AOP and Annexe 9. Lot 4 abandoned by EPFL on 12 Nov 2026 (SIMAP 43773-02). Schematic map, not to scale.

### Two of EPFL’s own files disagree by 27 % on lot 5: the price sheet asks for more nitrogen than the tank received.

Source: Redrawn from the Ziva Project “Gaz de laboratoires 2026 | SIMAP 43773” with the 10 public tender documents, 15 November 2026. Cells from Annexe 7, sheet 3.5, rows 4 and 5; values from Annexe 9, p. 24. Conversion at 1.25 kg per Nm³ of nitrogen. The five findings with their sources as in Ziva’s reply.

### One tank sets the rhythm: EPFL 05 needs about 130 fills a year, close to a third of lot 1’s deliveries.

Source: Annexe 9 (tank inventory, fills in 2025) and the delivery plan Ziva set up in the same Project, 15 November 2026. Fills a year = 2025 fill ÷ (75 % of the tank volume × 0.808 kg per litre), assumptions in yellow in the workbook; the bidder replaces them with its own.

### Under EPFL’s price formula, 10 % above the cheapest offer costs 0.52 of the total points.

Source: AOP, chapter 5.7 (p. 24) for the formula and 5.1 (p. 22) for the 60 % weight of price. Points recomputed by Ziva in the criteria sheet of the same Project, 15 November 2026.

### Ziva follows the gas notices on SIMAP: since September 2026, one lot abandoned, one new medical gas tender and two notices filtered out.

Source: simap.ch, publications 43773, 44873, 32832, 47631 and 46164, read on 15 November 2026. Redrawn Intelligence view with a search profile for gas supply set by Zephior; no bidder or award recipient is shown.
