JWCS peer-reviews the full breadth of fire-domain documentation: fire strategies, Concept Design Statements, Technical Requirements Specifications, Materials Compliance Registers, Inspection and Test Plans, Commissioning Test Plans, Cause and Effects matrices, S1088 submissions, concession applications, FRAs, evacuation analyses, and handover documentation packs. The review engagement scopes equally well across feasibility-stage documents, in-flight design submissions, retrospective audits of legacy documentation, and final pre-handover assurance packs.
Reviews are run against discipline-specific checklists spanning fire strategy, fire detection, sprinkler, gas suppression, low-pressure water mist, dampers, firestopping, fire doors, enclosures, compartmentation, S1088 submissions, concessions, FRA, evacuation, and core-quality criteria. Findings come as a comment register ready for direct input into the project’s Master Comments Tracker — each comment cross-referenced to standard clause, document section, criticality, and recommended action. Where the deliverable carries quantitative work, JWCS independently re-runs the calculations as part of the review.
Engaged by client-side fire authorities scrutinising principal-contractor submissions, by principal contractors validating sub-contractor design output, by insurers and approving authorities reviewing developer-side submissions, and by asset owners running retrospective audits of legacy handover packs. Typical turnaround: 5-10 working days for a fire strategy or full review; faster for narrower scope.
This review discipline is not limited to rail. Fire strategies and fire-engineering documentation prepared by others for non-rail buildings can be reviewed on the same rail-led basis, reading the governing code by premises class (BS 9999 and Approved Document B for buildings other than dwellings; BS 9991 for residential buildings) and drawing on held, rail-applied standards knowledge. This buildings review work is delivered through embedded, client-confidential engagements and is a developing part of the practice, with railway infrastructure remaining the core specialism and the body of delivered experience. JWCS reviews the documentation as an independent reviewer and does not thereby author non-rail buildings fire strategies, nor take any Building Safety Act 2022 higher-risk-building duty-holder, Principal Designer, or accountable-person competent-person role.
