"(2) The following operations are not construction operations within the meaning of this Part - (d) manufacture or delivery to site of - (i) building or engineering components or equipment, (ii) materials, plant or machinery, or (iii) components for systems of heating, lighting, air-conditioning, ventilation, power supply, drainage, sanitation, water supply or fire protection, or for security or communication systems, except under a contract which also provides for their installation;"
"I have therefore come to the conclusion that in relation to the Services under the Subcontract in this case, the only operation which is excluded from being a construction operation by section 105(2)(c)(ii) is the erection of the steelwork for the pipe racks and pipe bridges and not the prior activities of fabrication drawings, off-site fabrication or delivery to site of the fabricated steelwork. It follows that I consider that Cleveland Bridge is correct in its approach to the division between construction operations and excluded operations in relation to the Services under the Subcontract."
"In this Part a "construction contract" means an agreement with the person for any of the following - (a) The carrying out of construction operations (2) References in this Part to a construction contract include an agreement - (a) to do architectural, design or surveying work, or (b) to provide advice on building, engineering, interior or exterior decoration or on the laying-out of landscape in relation to construction operations (5) Where an agreement relates to construction operations and other matters, this Part applies to it only so far as it relates to construction operations."
"80. It appears to me therefore that by reference to the subsequent observations of Akenhead J himself Ms Chambers is right to say that the decision in Air Design is authority only for the proposition that where an adjudicator is properly appointed under a contract about which there is or can be no dispute, then he may also have jurisdiction to resolve jurisdictional issues if they are coincidentally part of the substantive dispute referred to him. 81. In my judgment it is clear that this proposition cannot on any view be said to apply to the present case where, on the findings I have made, the defendant was correct in its contention, which it maintained clearly before the adjudicator, but which was always disputed by the claimant, that there was never any initial concluded contract about which there was no dispute and that the claims made in the adjudication were all advanced under three separate contracts. It follows that the adjudicator could not properly have been appointed under any version of the initial concluded contract as contended for by the claimant, because no such contract was ever formed, in circumstances where there was a substantial dispute between the parties as to whether or not there was such a contract, or a series of separate contracts covering the same matter, and in circumstances where there were differences of substance in the adjudication procedures applicable to the differing contracts as well as in the other terms of those contracts. It is difficult to construe this as a case where the adjudicator was required, as part of the substantive dispute referred to him, to decide whether or not the subsequent orders were variations of the original order. The claim as advanced was a simple final account claim under a sub-contract, whereas the question was to whether or not the claim advanced arose under one or more than one contract was raised fairly and squarely as a question of jurisdiction, and the adjudicator decided it accordingly. In such circumstances there can, in my judgment, be no question of the court concluding that his answer on that question should, even if wrong, nonetheless be temporarily binding on the defendant, who never agreed to jurisdiction upon him to decide that question."
"Breaches of the rules will be material in cases where the Adjudicator has failed to bring to the attention of the parties a point or issue which they ought to be given the opportunity to comment upon if it is one which is either decisive of or of considerable potential importance to the outcome or the resolution of the dispute and is not peripheral or irrelevant and whether the issue is decisive etc. is a question of degree."
"If BBGL had known that this was the Adjudicator's line of thinking, BBGL could have (a) attempted to secure witness statements from those present at the Design Interface Meeting on23 February 2017 ; and (b) pointed out the above inconsistency out [sic] (namely that even Cubex did not suggest a contract was concluded at the Design Interface Meeting on23 February 2017 )."
