Question 1

Who is a Principal Designer under the BSA 2022?

Accepted Answer

The Principal Designer is appointed by the Client to plan, manage, monitor, and coordinate the design work during the design phase of a higher-risk building project. This is different from the CDM Principal Designer role, though they may be the same person.

Question 2

What are the Principal Designer's main duties?

Accepted Answer

Principal Designers must coordinate design work to ensure building regulation compliance, facilitate cooperation between designers, identify and manage design risks, maintain the Golden Thread during design, and prepare information for Gateway 2 submissions.

Question 3

Can the same person be CDM and BSA Principal Designer?

Accepted Answer

Yes, the same individual or organisation can fulfil both roles, but they are legally separate duties. Threadsovereign helps you track and evidence both sets of responsibilities.

Question 4

How does Threadsovereign help with designer coordination?

Accepted Answer

Threadsovereign provides a shared workspace where all designers can access project information, upload deliverables, track interdependencies, and communicate. The Principal Designer gets a dashboard view of all design work progress.

Question 5

What happens to my responsibilities at Gateway 2?

Accepted Answer

At Gateway 2, the Principal Designer must confirm that design work complies with building regulations. After Gateway 2 approval, responsibilities may transfer to the Principal Contractor for the construction phase. Threadsovereign manages this handover seamlessly.

Question 6

Is Threadsovereign built to submit to the BSR portal?

Accepted Answer

Threadsovereign prepares, evidences, and tracks work you still file on the official Building Safety Regulator and GOV.UK portals. Duty-holders remain responsible for official submission. The platform keeps correspondence, portal references, readiness scorecards, and an auditable golden thread so what you submit is complete and defensible — it is not a substitute for the regulator’s portal.

Question 7

How do Gateway and BSR submissions work in Threadsovereign?

Accepted Answer

Threadsovereign is built to prepare and evidence submissions to the BSR portal. It validates structured data against checklist requirements, provides a portal-day pack (GOV.UK building-control links, checklist status, correspondence, attestation register, HSE reference reminder), records local submission trace references for your audit trail, and captures manual HSE portal references after you file officially. Enterprise organisations can optionally enable a live HTTP BSR connector when customer middleware and platform credentials are configured — HSE does not publish a public duty-holder REST API, so official filing remains on GOV.UK. The platform does not replace the BSR or GOV.UK portals and never auto-files gateways, KBI, or occurrences to HSE.

Question 8

Does Threadsovereign support CDM 2015 and non-HRB projects?

Accepted Answer

Yes. The PD portal includes CDM client duty records, construction phase plan management, HSE F10 notification tracking, Pre-Construction Information pack distribution, and a construction products register (including UKCA/UKNI declaration tracking under the Construction Products Amendment Regulations 2025) — supporting BRAE 2023 duties on all construction projects, not only higher-risk buildings. The register links products to golden thread evidence; it does not verify certifications against official UKCA databases.

Question 9

Does Threadsovereign track PAS 867 competency evidence?

Accepted Answer

Yes. Every paid plan includes a PAS 8671/8672/8673-style competency evidence matrix — role × person × review with verification workflow and certification expiry reminders. This supports procurement and BSR competence questions for Principal Designers, designers, and Accountable Persons. Threadsovereign records evidence duty-holders supply; it is not a BSR-accredited competence certification scheme. See threadsovereign.co.uk/principal-designer-software. Background: threadsovereign.co.uk/duty-holder-competence.

Question 10

Does Starter include HRB and Gateway workflows?

Accepted Answer

Yes. Starter is capacity-limited, not compliance-limited. All plans include Gateway 1, 2, and 3 workflows, golden thread, BSR registration, all 16 KBI categories, safety case principles, mandatory occurrence reporting, occupied statutory paths, and resident engagement. Professional adds maintenance CMMS, analytics, automation, integrations, and higher capacity.

Question 11

Are statutory BSA workflows paywalled behind higher tiers?

Accepted Answer

No. Core statutory workflows — gateways, golden thread, BSR registration, KBI, safety case, occurrence reporting, resident information rights, complaints, engagement, and BSA readiness tools (scorecard, portfolio, deadlines, evidence packs, portal-day pack) — are available on every paid plan. Professional and Enterprise add operational tooling (maintenance CMMS, analytics, advisory PDF pre-fill, advisory drafting, natural-language search, SMS/push, webhooks, DocuSign, calendar sync) and higher capacity. Occupied maintenance is the main occupied-phase feature gated to Professional and above.
