"Notwithstanding the condensation and/or other ingress of water the plywood would not have delaminated and lost its integrity resulting in the premature failure of the lead flat roof had all the plywood supplied and fitted been in accordance with the Specification."
"….. and in the alternative, the claimants claim the cost of replacing the plywood. These are estimated to be£185,000 plus VAT….."
"…….. With regards to the valuation exercises…..The fundamental problem as accepted by both parties' experts, is the roof is defective and failed due to lack of ventilation. The remedial costs are the costs of the entire replacement exercise, so for example there is no point in addressing the clips and flashings issue in isolation. Our client has not made a claim for that cost in isolation. Obviously, the clips and flashings had to be replaced as part of the wider exercise of stripping the defective roof and relaying it. You are embarking on this salami slice approach to the valuation to support your argument that there is not a single defect but a series of defects each below the relevant value threshold. That is an artificial and self-serving approach and whilst we are agreeing to your proposed valuation exercise to avoid an argument over the scope of the expert instruction, this should not be taken as a tacit concession that we agree the approach is appropriate or that there is any merit in it. ………."
"……. We remain concerned that the parties are potentially spending large amounts of money on what we believe to be an entirely unnecessary task. It seems to be common ground that the problem here was caused by lack of ventilation. The plywood substructure has failed. The only relevant issue is whether the cost of rectifying the position cost more than£100,000 . Bearing in mind that scaffolding costs alone with VAT exceeded£85,000 , it seems unlikely that the work could ever have been completed for less than£100,000 ."
