Moresk Cleaners v Hicks

Due to adverse ground conditions, the engineers gave eot which was more than doubled the time for completion but the plf also claimed to be entitled for adjusted rates and additional sums of payment to cover some unforeseen conditions. The govt. contended that the plf was bound to them and that the engineer could not adjust the rates.
P.C: The The plf has the right to claim the additional sums based upon the adjusted rates as it was certified by the engineer (whom had been formally delegated with the task of design by the client).
Thomas Saunders Partnership v Martin Harvey

Contractors
• Where the contractors are not involved in design and build , their design liability will limited to :

University of Glasgow v William Whitfield and John Laing Construction

Brunswick v Nowlan
The resp (def), engaged an architect to design a house. The app was the main contractor. After construction, the roof leaked badly due to basic design inadequacies. The resp sued the app for the resp for the defect.
Supreme Ct of Canada per Ritchie J:“ The app carried out the work of building the house
without supervision of any engineer or the assistance of the architect and I think that the appellant must therefore be taken to have accepted the fact that the resp were relying entirely on its skill and attention as a contractor… in my opinion, a contractor of this experience should have recognized the defects in the plans…I think the contractor was under a duty to warn the resp of the danger inherent in executing the architect’s plan.
Sub contractors/suppliers
• Nominated SC/SPIf the the NSC is made responsible for the design work, the main contractor (who is contractually responsible to the client), will have recourse to the NSC for any inadequacies.
- It is a common practice, where NSC is requested to give formal warranties to the client, which create a contractual relationship with the client.
Greater Nottinghamshire Co-operative Society v Cementation Piling and Foundation Co
The NSC entered into a direct collateral warranty for design of their piling work with the plf (client). When the plf work caused loss, the sued them.
CA: The warranty only covered design and materials but not workmanship which was the cause of the loss…no action for the economic loss suffered could proceed…
