To close “What is the final fire-engineering position”, identify the controlling document and responsible owner, list every design, client, statutory, contractual and evidence gate still open, then issue one position that construction and handover can rely on.

A seemingly simple request can depend on several disciplines, the client, a certifier or a specialist trade.

They can provide a view but cannot commit the client, company, regulator or another designer.

Consultants test positions privately because the interface is shared or politically sensitive.

Trust can accelerate honest coordination; history and alliances can also distort the current decision.

The apparent delay may be an unresolved design-leadership issue rather than simple inaction.

A consultant may qualify a response instead of openly contradicting a peer.

No appointment clearly owns the missing design, coordination or evidence task.

Acceptance may extend beyond available information, competence, authority or fee.

Earlier briefs, approvals and conversations may still shape the consultant response after the delivery model changes.

Commercial pressure cannot remove duties around competence, safety, compliance and records.

A genuine site need still requires adequate facts, checking and the right signatory.

The consultant may be waiting on survey, selections, another design, client direction or trade data.

Redesign, unpaid work or changed scope can appear as a technical delay.

The people producing information may not know assumptions held by project leaders.

A small design response can disrupt sequence, fabrication, access, rework and programme.

Egress, compartments, openings and materials.

Egress assumptions, sprinkler assumptions.

Additional stairs, shafts and fire-isolated construction consume area and create structure, doors, services, finishes and programme cost.

List occupant, geometry, material, system, management and operating assumptions and assign who must protect each one.

A practical change may affect fire engineer performance, approvals and connected design assumptions and obligations beyond the immediate trade.
