Conterra Restoration Ltd. (Conterra) claimed $109,451.35 from Irving Moishe Kirsch (Kirsch) for additional concrete work and waterproofing performed on his property.
Kirsch argued that these additional works required written change orders under their contract.
The court found that the contract was not a fixed-price agreement and that the additional concrete work fell within the scope of work priced on a per-unit basis, thus not requiring a written change order.
While the waterproofing work was outside the original contract scope, the court found that Kirsch had orally authorized it.
The court also held that Kirsch's oral approvals constituted a waiver by conduct of any strict contractual requirement for written change orders.
Consequently, Kirsch was found liable to Conterra for the claimed amount.
Kirsch's third-party claim against Pancon Engineering Ltd. for contribution and indemnity was dismissed.
