Which Level 2 dampers still have no signed test record?
| Damper | Room | Test record |
|---|---|---|
| MSD/L02/0207 | L02-0408 COMMS EQUIPMENT ROOM | Ready to witness |
| MSD/L02/0213 | L02-0410 LIFT LOBBY CIRCULATION | Ready to witness |
| MSD/L02/0221 | L02-0414 MAINTENANCE STORE | Not installed |
| MSD/L02/0224 | L02-0416 MCC CONTROL ROOM | Ready to witness |
MSD/L02/0221 is the one to chase first. It is not installed yet, so it holds up the RA-01 leakage test as well as its own drop test.

One record, from tender to handover.
One evidence trail through every seat on the job: the number a subcontractor prices is the number a commissioner signs.
For subcontractors
Price the scope from the specification, measure the quantities from the model, hand over the records.
Explore Archie for subcontractors
For independent commissioners
Scan the overlay instead of auditing the spreadsheet, and sign a record that locks on signing.

Archie is not a tool your team uses. It is a member of your team.
The method
Archie never guesses the numbers.
Every quantity, allowable and test pressure is computed by a deterministic engine. The language model only reports what the engine computed.
Every discipline, one evidence trail.
The register.
Tag, type, size, system, room and level, with the basis and the source on every row.

Asset registerOne row per damper tag, matched to its room, its system and the thing that proved the room. A tag whose room cannot be proved is printed with the room withheld.

Area basis
Every duct element is measured once. A crossover section that two systems both draw through is held against one of them only, so the total is the fabric that exists. This is the basis for a quantity.
Reading now: Element area, 1,399.0 m² across 7 systems. The other basis reads 1,479.4 m². The two are never added together.

Scope gaps.
Specification, drawings and the priced bill are read as three independent sources. Anything missing from one is raised as a gap.

Scope gap registerThe specification, the drawing set and the priced bill are read separately, then compared. A system that is not in all three is a gap, and a gap is worth money or a fire engineering consequence.
