AMEC BCS Ltd (“AMEC”) was a concrete sub-contractor on both the Wellcome Centre (“Project 1”) and Castlepoint car park (“Project 2”) construction projects. It engaged Arcadis Consulting (UK) Ltd (“Arcadis”) to carry out design work to both these projects. The parties first agreed terms in relation to Project 1 on 8 November 2001 (“the November Terms”). The plan was that both parties would enter into an overarching “Protocol Agreement” which would govern all works under both projects. However, prior to finalising the T&Cs of this Agreement, each project would have specific contracts but carried out to the same general T&Cs. AMEC received instructions from the Employer to start work on Project 2. AMEC instructed Arcadis through 2 letters from 6 March 2002 to commence work according to the terms “that we are currently working under”. Arcadis sent an acknowledgment on 8 March and stated certain terms still needed to be agreed in a letter of 22 March. The Protocol Agreement was never formally agreed between Arcadis and AMEC and it later transpired that works to Project 2 were defective. The cost of cure (demolition and reconstruction) was estimated to be c. £40 million. Arcadis brought a claim to the TCC, seeking a declaration that the T&Cs that AMEC had offered on 6 March 2002 were the November Terms, which stated that Arcadis’ liability would be limited to £610,515. AMEC argued that no limit of liability had been formally agreed.
Coulson J (as he was at the time), handing down his judgment in the TCC[i], found that in the absence of the Protocol Agreement, there was no limit of liability for Arcadis’ works. He accepted that under the legal principles derived from G Percy Trentham v Archital Luxfer Ltd  1 Lloyd’s Rep. 25, the courts should strive to find a contract where work has been performed and that a presumption stands towards such an outcome in order to avoid quantum meruit claims. In the absence of finalising the Protocol Agreement, he found a binding, “simple” contract between the parties, formed through a letter of intent, which Arcadis accepted through the conduct of commencing the works, and which did not incorporate the November Terms (including the limitation on liability).
The Court of Appeal have overturned this decision.
Gloster LJ (with whom Holroyde and Underhill LJJ agreed) found that the parties had agreed terms to limit Arcadis’ liability to £610,515. She identified that the following issues were relevant:
In relation to i) Gloster LJ found that Arcadis’ submissions on offer and acceptance made sense:
Gloster LJ, in considering the distinction in ii), found that as well as the Protocol Agreement which both parties had intended to conclude, there was an interim contract with finalised terms in place when Arcadis commenced works on both projects.
Turning to iii) she rejected Coulson J’s interpretation that the parties agreeing to “terms and conditions we are currently working under with yourselves”, as stated in the letter of intent, meant that there was still uncertainty of terms as they were under negotiation:
The construction industry is a fast-paced sector where parties are regularly time-pressured to complete extensive projects to challenging deadlines. Although not ideal, often parties choose to commence works prior to finalising all T&Cs and executing a final contract. In such scenarios, the parties will have entered into preliminary negotiations and might choose to rely on a letter of intent.
This decision is fact-specific. However, it can give some comfort to contractors who have commenced works subject to agreeing a final contract. Interestingly, the November Terms themselves contained outstanding (although minor) matters to resolve, and Gloster LJ said the reasoning in British Steel Corp v Cleveland Bridge & Engineering Co Ltd  1 All E.R. 504 was another reason to decide differently. She suggested it was an “extraordinary result” to allow unlimited liability to be accepted by conduct where a contractor would never agree to such terms under a formal contract. Perhaps it might not be a step too far to suggest the court will view a party’s silence to terms when accepting by conduct as no greater acceptance of responsibility than they would have agreed in the negotiations that follow, especially where the other party is aware of any proposed caps at the time of instruction.
