(ii) The correct approach to the quantum issue
53 The insured sought to recover its costs of demolishing each wall and designing and constructing an adequate new wall. The new walls were erected where the old walls had stood and generally according to the same design and using the same materials. But unlike the old walls, they were constructed properly according to the manufacturer's system and the sub-contract specifications.
54 The issue of principle agitated by the insurer on the appeal was whether the insured was entitled to recover the reasonable cost of such walls, or whether (as the insurer contended) it was confined to the cost that would have been incurred if the old walls were reconstructed with their original faults.
55 In my view, the insurer's submission should be rejected for absurdity.
56 No one suggests that it would have been reasonable to erect walls with the substantial defects of their predecessors. For one thing, this might have exposed the insurer to a second set of claims if the new walls were to start collapsing during the period of cover.
57 The Insuring Clause stipulates that the basis of indemnity is to be "the full cost of repairs, re-instating or replacing the Property Insured… to a condition equal to its condition when new". See also the definition of "reinstatement" in Section 1(B) of the Policy (Blue 361). It would be an entirely forced reading of this language to construe it as suggested by the insurer. A sensible, commercial and natural reading of the words "condition when new" is to read them as connoting a condition equal to the property damaged but freed only of the fatal defect(s) that led to such damage.
58 There is an analogy with Colonial Mutual General Insurance Co Ltd v D'Aloia [1989] VR 161. A policy of fire insurance provided that if the insured buildings were destroyed by fire the insurer would pay to the insured "the costs incurred by the Insured in reinstating the Buildings in a condition equal to but not better or more extensive than their condition when new". The policy also required the insurer to pay the extra costs of reinstatement necessarily incurred to comply with relevant building laws. The Full Court of the Supreme Court of Victoria held that the issue of "reinstatement" was one of fact. Its starting point was a new building, the condition of which was "equal to" and no better or more extensive than the old. The Court said (at 167):
The words 'equal to' mean, in our opinion, that the reinstatement does not necessarily have to conform precisely in appearance, structure and configuration to the destroyed building. But basically there must be 'equality' in the sense of size, structural quality, amenities, space, plumbing, electrical, gas and like installations.
59 The Court gave illustrations of reasonable "reinstatement" that produced a new building with requisite differences in value and configuration.
60 The insurer complains that the insured chose not to conduct its case as to quantum on the basis of proving the cost or value of what was destroyed. The insured was, however, within its rights because of the last two sentences of the Insuring Clause (set out above). Later provisions in the Policy also stipulate that it extends to include:
A. Architects, Surveyors', Consulting Engineers', Project Management and other Fees
Architects, Surveyors', Consulting Engineers', Project Management, legal and other fees and costs, together with the Insured's costs necessarily incurred in repair or reinstatement or replacement of any Property Insured consequent upon its loss or damage (including the preparation of claims).
B. Debris Costs and Expenses
Costs and expenses necessarily incurred by the Insured for:
(i) Regaining access to the Contract Site
(ii) Removal, storage and/or disposal of Debris and/or any of the Property insured which is no longer useful for the purpose for which it was intended and/or material foreign to the Contract
(iii) Dismantling or demolition
(iv) Cleaning, decontaminating and preparing the site, shoring up or propping
(v) Temporary repairs and the restoration or resumption of original working conditions
where loss or damage occurs in the vicinity of any Contract Site and it becomes necessary for the insured to remove, store and/or dispose of debris, wreckage or detritus in order to resume original working conditions.
61 The insured event occurred in 2000. The actual cost incurred by the negligent sub-contractor in 1999 is not the measure of the insured's loss in 2000.
