The galvanised steel cold formed components connecting the wall and roof sections to the portal frame, namely the purlins, the cladding rails and the connecting brackets (items 1–3 of the Scott schedule). Its purpose was to “optimise and integrate structural, civil and architectural solutions [and] clarify technical tender design assumptions and intent”. A key document relied upon by Blackpool was the Functional Procurement Specification (a contract document). Design life and meaning of building structure. Engineers use an iterative process to fine tune the various elements into final structural element designs. as per the default position in the Works Information). The best way to head off such a risk, is to ensure that the contract is drafted appropriately from the start and ensure that key terms are defined or set out in appropriate detail so that there can be little argument down the track. The Court considered the evidence of structural engineers, references to definitions of structure in various standards and specifications, legal textbooks, and the contract documents, but did not consider any of them to be decisive. Once an initial conceptual design is complete, an engineer will turn their attention to system design in a top down manner. The cantilever roof soffit panels and the wave-form cladding panels formed part of the external shell and were subject to the 25-year design life requirement. For double-coated external facing components such as the wall cladding panels, tram doors, and the other coated external components including the remaining Scott schedule items, the Court held that the coating should be required to have the same design life as the underlying structure. Beyond review of conformance to the structural design, engineers will also monitor construction progress on behalf of the client and will often perform site inspections to make sure construction process is progressing and installation of products is without errors. Those sealed designs are reviewed by the EOR and either approved for manufacture or returned for revisions. However, the Court did not consider that the same arguments applied to the cold formed components because they were not sited externally and did not have the same aesthetic importance as the other items. Once an initial conceptual design is complete, an engineer will turn their attention to … The Court said if they did not, the words “external shell” would not have any sensible meaning (which could not be correct). the steel cold formed components) were not part of the “structural frame” (which was to have a 50-year design life) in item 1.9 of the RPS design log. Further in the construction process, the engineer is often called upon to review RFI and deferred submittals, obtain code approvals or prepare construction schedules. This broad analysis information is compiled into initial structural construction plans. Volker’s position was that the contractual design life of the wall cladding panels was 25 years and the contractual design life for the cold formed steel components, roof steel components and other components was 20 years (e.g. Blackpool argued: “…in the case of a portal frame structure the building structure comprises three essential elements, namely the primary steel structure, the secondary steel structure and the external walls and roof, so that all are within the definition … (a) the term building structure naturally includes all load bearing or load transmitting elements of the depot building; (b) the cold formed components and the roof components are secondary structural elements within the building; (c) the wall cladding panels and cantilever soffits form part of the walls and the roof and, thus, form part of the building structure because: (i) as such, they are part of the overall structure of the building; and (ii) the walls and the roof transmit wind and other loads which bear on them as external structures.”1.
