“GENERAL The Sub-Contractor will execute and complete with the best workmanship and materials the Sub-Contractor works strictly in accordance with the listed documents and Conditions in the Order and instructions of the Main Contractor and to the full satisfaction of the Main Contractor, the Employer, or it’s Architects/Contract Administrator and subject to and with the benefit of the General conditions set out below… 3.2 The terms of the Main Contract shall be deemed to be incorporated in the Order without any modification thereto insofar as they are not repugnant to or inconsistent with that from which is stated herein and the Sub-Contractor shall observe perform and comply with such of the provisions of the Main Contract as are applicable to the Sub-Contractor and/or shall observe/perform and comply with those additional provisions as the Main Contractor shall request at no additional cost. 3.3 The Sub-Contractor shall indemnify the Main Contractor from and against any breach, non-observance or non-performance by the Sub-Contractor or his servants of the provisions of the Main Contract… THE WORKS … 5.2 If not previously submitted, within 7 days from the date hereof the Sub-Contractor shall submit to the Main Contractor for approval a programme showing the Sub-Contractor’s proposals for the sequence and timing of all activities within the scope of the Sub-Contract Works with full details of its proposals for the supervision and manning of the Sub-Contract Works. Such proposals may be incorporated within the Main Contractor’s programme but the Main Contractor reserves the right at its absolute discretion to vary the same to meet the requirements of the Main Contract.”
“10.1 Should the Sub-Contractor fail to comply with the conditions of this Agreement or, by any act, omission or default, interfere with the regular progress of the Main Contract Works, or completion of the same the amount any loss or expense thereby suffered by the Main Contractor as bona fide assessed by the Main Contractor shall be regarded as a debt which the Main Contractor may set-off in accordance with the provisions herein contained. 10.2 If the Sub-Contractor shall cause the Main Contractor expense, damage, loss or other costs or liability whatsoever by reason of any breach of this or any other contract between the Parties or by any tortious act under this or any other contract between the Parties…then without prejudice to and pending the final determination or agreement between the Parties as to the amount of such expense, damage, loss or other liability, indemnity or contribution or payment the Main Contractor shall be entitled to deduct from any monies payable to the Sub-Contractor now or in the future under this or any other contract and/or the Sub-Contractor shall pay such sum as the Main Contractor shall bona fide estimate (if not already ascertained or agreed) to be the amount of such expense, damage, loss or liability such estimate to be binding and conclusive upon the Sub-Contractor until such final determination or agreement…”
“14.1 If the Sub-Contractor is delayed in completing the Sub-Contract works due to the default or actions of the Main Contractor or any other Sub-Contractor for any reason, then the Sub-Contractor must notify the Main Contractor in writing of the reasons why progress has been materially affected. The Sub-Contractor shall at the same time also submit a detailed forecast of the consequences of those reasons. If the Main Contractor considers that an extension of time may be due then it shall inform the Sub-Contractor within 12 weeks after the issue of Practical Completion of the Main Contract. 14.2 The Sub-Contractor shall constantly use his best endeavours to prevent or minimise any delay in the progress of the whole or any part of the Sub-Contract works.”
“Once other trades commence with their works on site, there would be no guaranteed use of the tower crane and a coordinated crane booking in system will be implemented by Mulalley for use of the crane by all required sub contractors.”
“Their Lordships do not think it necessary to review exhaustively the authorities on the implication of a term in a contract which the parties have not thought fit to express. In their view, for a term to be implied, the following conditions (which may overlap) must be satisfied: (1) it must be reasonable and equitable; (2) it must be necessary to give business efficacy to the contract, so that no term will be implied if the contract is effective without it; (3) it must be so obvious that ‘it goes without saying’; (4) it must be capable of clear expression; (5) it must not contradict any express term of the contract.”
“What is said in the notice of motion is that there should be an obligation to proceed ‘with due diligence and expedition’, but what is due diligence and expedition depends, of course, on the object which is sought to be achieved. If one is obliged to achieve a certain object within 12 weeks, it may be necessary to exercise much more speed than if your only obligation is to produce it in 24 weeks or indeed in 4 years. The same applies to diligence. You cannot have diligence in the abstract. It must be related to the objective.”
“Taken together the obligation upon the contractor is essentially to proceed continuously, industriously and efficiently with appropriate physical resources so as to progress the work steadily towards completion substantially in accordance with the contractual requirements as to time, sequence and quality of work. Beyond that I think it impossible to give useful guidance. These are after all plain English words and in reality the failure of which clause 25(1)(b) speaks, is, like the elephant, far easier to recognise than to describe.”
“Going slow. Interim slowness not resulting in a failure to complete on time may not be a breach of contract at all. If it is, damages solely following from a failure of the contractor to perform the works at the contract rate will, if any, ordinarily be small.”
“One’s first impression, on reading clause 19, is that the contract does, as a matter of construction or by implication, provide that the contractor shall carry out the contract works with due diligence and expedition. But, on further consideration, I do not think that that is the right conclusion. The point is very nicely balanced and, for reasons which will presently appear, the result in this case does not depend upon it. However, in point of form I do have to decide it, as I must affirm or vary the answers which the arbitrator gave to the preliminary questions which were argued. I see no sufficient reason to disagree with the answers that he gave. Accordingly, I conclude that although neglect by the contractors to execute the works with due diligence and expedition would entitle the employers to discharge them, under clause 19, it would not by itself be a breach of contract on the part of the contractors. If I had not reached that conclusion, I would have held, without hesitation, that due diligence and expedition must be interpreted in the light of the other obligations as to time in the contract.”
“The plain fact is that if there is no obligation to do more than complete by a certain date, a contractor is not subject to the operation of the proviso to clause 51 if he chooses to conduct his programme in a manner which suits him. It may or may not be that in the end he will get a price increase benefit from so doing.”
“The words ‘the progress of the works’ are in my judgment directed to requiring the sub-contractor to carry out his sub-contract works in such a manner as would not unreasonably interfere with the actual carrying out of any other works which can conveniently be carried out at the same time. The words do not however in my judgment require the sub-contractor to plan his sub-contract work so as to fit in with either any scheme of work of the main contractor or to finish any part of the sub-contract works by a particular date so as to enable the main contractor to proceed with other parts of the work…In my judgment clause 11.8 does not exclude or modify the general principle applicable to building and engineering contracts, that in the absence of any indication to the contrary, a contractor is entitled to plan and perform the work as he pleases provided that he finishes it by the time fixed in the contracts.”
“88 I respectfully agree that clause 11.1 does not require the sub-contractor to comply with the detail of the main contractor’s programme, either generally or in relation to the work of other specific sub-contractors. My own view, however, is that the words ‘reasonably in accordance with the progress of the Works’ goes somewhat beyond the negative duty ‘not unreasonably to interfere with the actual carrying out’ of other works. The sub-contractor knows the nature of the main contract works and the place of the sub-contract works in them. As Keating suggests in the passage referred to by Judge Gilliland this obligation presupposes that the main contract works are proceeding regularly and diligently. The ‘progress’ referred to is therefore, I think, that expected and observed in the light of those facts, although the obligation is only to proceed ‘reasonably’ in accordance with that progress.”
