A Roytec-designed façade — pre-construction design developed to a coordinated, approval-ready state

Service 03

Pre-Construction Façade Design (PCSA)

Specialist façade design through the pre-construction period — RIBA Stage 3–4, developed to Building Control / BSR Gateway approval under a PCSA.

Engaged under a Pre-Construction Services Agreement, we develop the façade design through RIBA Stage 3–4 to the level of completeness needed for Building Control and Building Safety Regulator (BSR) Gateway approval — before the construction package is let. We start with a Buildability Check & Technical Coordination phase, resolving the structural, fire and interface questions and getting them formally signed off with the wider design team, before committing to full design development. It's the design certainty needed to fix a programme and pass a Gateway — and the PCSA fee credits against a subsequent manufacturing-and-construction appointment if we carry the design through.

How we work

01

Phase 1 — Buildability Check & Technical Coordination

Before any design development, we resolve the structural, fixing, fire and interface questions and get them formally confirmed with the engineers, fire engineer and architect. Phase 1 closes with a written sign-off — so design only develops on agreed foundations.

02

Phase 2 — Design Development

We develop the cladding design to Building Control Full Plans / Gateway approval — elevations, sections, setting-out, interface and fire-barrier details — iteratively through coordination workshops rather than a revision-tennis cycle.

03

Approval & onward to construction

The approved design, cladding-discipline BIM model and compliance pack hand over ready for construction. If we're carried through to the Stage 5–6 manufacturing and construction package, the PCSA fee is credited against it.

What you receive

—GA elevations, sections and details defining the cladding design
—Setting-out drawings — panel positions, alignments and joint locations
—Fire-barrier, fire-stop, cavity-closer and cavity-compartmentation plans — bespoke details manufacturer-verified and fire-engineer-approved
—Interface details at junctions, soffits, parapets and roof edges
—Cladding-discipline 3D BIM model (IFC) for your federated model
—Building Control compliance narrative + fire-test evidence and material-certification register
—Structurally verified solutions — wind-load, fixing and framing calculations
—U-value calculations and condensation risk (thermal) analysis

Subject to a separate appointment

  • Stage 5–6 production/fabrication and as-built drawings (separate appointment)
  • Measured and opening-up surveys (client-provided)
  • Federated BIM coordination and cross-discipline clash detection (principal designer)

A pre-construction buildability study — the façade build-up resolved in BIM before a panel is made.

What it means for you

Design resolved and approval-ready before the package is let — backed by £5M professional indemnity and £10M public liability cover — so the build starts on a coordinated, Gateway-ready design, not a hopeful one.
