The Two Oceans Aquarium Trust operated an aquarium in Cape Town. Prior to the trust’s formal establishment and the conclusion of a consultancy contract, Kantey & Templer, consulting engineers, assisted a joint venture investigating the feasibility and design of the aquarium. The engineers recommended a design option using polyurethane lining to waterproof the tanks rather than water-retaining concrete. After construction and operation, the lining proved porous, allowing seawater to corrode the concrete reinforcement, necessitating extensive remedial works and causing loss of revenue. The trust claimed damages for the cost of repairs and mitigation, alleging that the respondent’s negligent pre-contractual design advice caused pure economic loss.
