Implementation roadmap and stage gates

The Project Office › Cedwyn Estate › Implementation roadmap

Work package P2-DEL-01
Method Stage-gated delivery
Status Indicative; not a dated baseline

The project is active as a digital and planning exercise. The physical museum follows staged evidence and approval gates; no opening date, land parcel or construction budget has been set.

Proposed stages

Authorise one stage at a time

Stage	Work and products	Exit gate
S0 · Research setup	Sources register; architectural brief; acreage reconciliation plan; stakeholder and question log	Terms of reference and research standards accepted
S1 · Land reconnaissance	GIS atlas, constraints map, cadastral/title checks, shortlist and local specialist notes	At least one viable route to land or an existing building identified, or a stop/amend recommendation issued
S2 · Concept and community	Concept plans, visitor journey, landscape brief, accessibility, interpretation and community engagement	Concept reviewed by local professionals and relevant stakeholders
S3 · Business case and consents	Capital and operating estimates, delivery model, local permissions path, risk plan, funding and partner register	Affordable option, lawful site route, funded next stage and acceptable risk position
S4 · Detailed design and procurement	Surveys, design coordination, specifications, tenders, contracts, construction and operational plans	Approvals, full finance, procurement and acceptance criteria authorised
S5 · Build, fit out and opening	Construction, testing, collection/display installation, staffing, emergency procedures and trial visits	Safety, access, building and operational readiness checks passed

Stage durations are deliberately not fixed until local access, approval pathways, consultant scope and cost estimates are known.

Parallel delivery lanes

Progress before physical opening

Lane	Near-term result	Dependency
Wales virtual reconstruction	Source-graded scenes, navigation prototype, rights register and estimate	Source access and digital-scope approval
Online museum presence	Public project site, enquiries, project documentation and change log	Content review, privacy, accessibility and service ownership
Physical site feasibility	GIS screen, local professional scope, candidate-site comparison	Cadastral data and local advice
UK legal work	Separately managed legal outputs, deadlines and budget control	Relevant legal instructions and procedural deadlines; not a prerequisite for Argentina research

Quality and change control

No silent scope expansion

All architectural and historical content receives a source, date, rights note and confidence/status label.
Concept drawings carry a permanent “not to scale / not a survey” label until replaced by verified survey products.
Land and construction decisions require written local specialist review and a costed option.
Every work package identifies product, owner role, cost cap, target date, acceptance test and risk controls before authorisation.
Any proposed scope change states effect on cost, time, quality, sustainability, risk and benefits before approval.
Public opening, prices, accommodation, weddings, equestrian facilities and visitor forecasts remain uncommitted until a relevant stage gate passes.

Reporting and decision cadence

Proposed governance

Monthly highlight report: stage status, deliverables accepted, spend and commitments by workstream, risks/issues, decisions needed, funding status and forecast. A stage-end report should include lessons, unresolved data gaps, updated business case and a recommendation to proceed, pause, amend or stop.

Until a local delivery team is appointed, role assignments are provisional. The Executive retains budget and continuation decisions; technical specialists certify their own scoped outputs; assurance is independent of the supplier who prepared the product.
