Historic building safety claims still depend on project evidence.
Building safety claims are often described as regulatory or technical disputes. In practice, they are also evidence disputes. When a historic building is later challenged, the commercial question is rarely limited to whether a defect exists. The harder question is whether the parties can reconstruct what was designed, specified, approved, installed, inspected, certified and handed over many years earlier.
The dispute in BDW Trading Ltd v Ardmore Construction Ltd concerned historic fire safety issues at a residential development and the enforcement of an adjudicator’s decision in the Technology and Construction Court. The case raised issues around adjudication jurisdiction, defective premises liability, historic records and whether alleged evidential difficulty was sufficient to resist enforcement. That made the case commercially important because it showed how historic building safety disputes can turn not only on technical defect allegations, but on whether the project record is strong enough to explain responsibility years after completion.
For contractors, the practical lesson is direct: the project record created during delivery may become the recovery record years later. Design responsibility, product approvals, installation evidence, inspection records, certification, correspondence and handover documents may all become central to liability, contribution, enforcement and settlement strategy long after the project team has moved on.
Why the case matters
The importance of BDW v Ardmore is not limited to the fact that a historic building safety claim reached adjudication. Its wider significance lies in what it says about the long commercial life of construction evidence. Building safety disputes often arise after the project team has moved on, the final account has been agreed, the development has been occupied and the original commercial context has faded. At that point, the parties are no longer dealing with live project recollection. They are dealing with the surviving record.
That creates a very different risk environment. The dispute may require the parties to establish what design responsibility was accepted, what the contract required, what fire strategy or safety-critical requirements applied, what products or systems were specified, what alternatives were proposed, who approved them, what was inspected, what was certified and whether the alleged defect sat within the contractor’s scope. Those questions cannot be answered properly by general recollection. They require records. That is why building safety claims are not simply technical exercises. They are structured evidential exercises. The party with the clearer record is usually better placed to explain responsibility, defend its position, pursue contribution, resist overstatement and manage adjudication strategy.
Historic claims increase the pressure on records
Historic claims create a particular evidential problem because the original project narrative often becomes fragmented. The people who made decisions may no longer be available. Project email accounts may have been closed. Design responsibility may have moved between parties. Subcontractor records may be incomplete. Product information may have changed. The contract may have been assigned. The building may have been altered. Later investigations may focus on issues that were not controversial during the original delivery phase.
In that environment, the contractor’s position depends heavily on whether the project record can stand on its own. A contractor may believe that it complied with the specification, followed the design, installed what was approved, relied on specialist input or carried out works in accordance with the contract. But belief is not enough. The contractor needs the documentary chain. The issue is not only whether the contractor has an answer. The issue is whether the contractor can prove it.
Why this matters for adjudication strategy
The adjudication dimension is also important. Adjudication is fast, and historic building safety disputes are often document-heavy. That combination creates pressure. If the record is incomplete, disorganised or difficult to reconstruct, the contractor may be forced to respond to serious allegations within a compressed timetable without the benefit of a clean evidential structure. That is commercially dangerous.
In adjudication, the question is not merely whether the contractor can eventually build an argument. The question is whether it can present a coherent answer quickly, supported by documents that substantiate the position being advanced. Historic building safety claims may involve complex issues of contractual scope, design responsibility, causation, defects, limitation, statutory duties, remedial cost and contribution. But the practical adjudication question is often simpler: can the responding party show, within the timetable, what happened and why it is not responsible for the whole of the claim advanced? That is where historic evidence becomes leverage. A contractor with structured records can respond with precision. A contractor without them may be left trying to reconstruct the project under pressure.
The commercial lesson for contractors
The practical lesson is that safety-critical evidence should be treated as long-term commercial protection, not short-term administration. Contractors involved in residential, façade, cladding, fire safety, structural, M&E, life-safety or other safety-critical packages should assume that the project record may be needed years later.
That record should be capable of explaining the full chain from contractual requirement to design decision, approval, installation, inspection and handover. It should show what the contract required, how the design developed, what was approved, what changed during delivery, what was installed and how compliance was demonstrated. This is not administrative tidiness. It is future recovery and defence strategy. The clearer the evidence chain, the stronger the contractor’s ability to explain responsibility, resist unfounded allegations and support any recovery or contribution position that may arise later.
Why close-out is not enough
Many contractors treat evidence as something to assemble at practical completion or final account stage. That is too late for safety-critical issues. By close-out, the project team may already be under pressure. The focus is often handover, snagging, payment and demobilisation. Records may be collected because the contract requires them, rather than because they are being structured around future responsibility.
That approach creates risk. The stronger position is to build the evidence chain during delivery. Product approvals, design decisions, installation records and inspection evidence should be captured when the decision is made or the work is carried out. If they are left until the end, the record may be incomplete, inconsistent or detached from the commercial context in which decisions were taken.
This is particularly important where works are safety-critical. The record should not merely show that documents existed. It should show the chain from contractual requirement to design decision, approval, installation, inspection and handover.
Legalbuild’s view
For Legalbuild, BDW v Ardmore reinforces the long-tail nature of modern construction risk. The building may be complete. The final account may be closed. The project team may have moved on. But if building safety issues later emerge, the commercial consequences of incomplete evidence can remain live for years. The strongest contractor position is built during delivery. Historic claims are much easier to manage where records were structured in real time around responsibility, compliance, scope and entitlement. Where the evidence has to be rebuilt from incomplete material years later, the contractor may still have arguments, but those arguments will be harder to advance with confidence.
The conclusion is clear: building safety evidence should be treated as part of commercial risk governance. Contractors should not wait for a claim, adjudication or remedial demand before asking whether the record proves their position. On safety-critical work, the record is part of the protection. It should be built deliberately, organised properly and preserved for the long commercial life of the building.
