      "verbatim_quote": "So, by failing to give the early warning, the costs incurred by the Contractor in excavating the structure were all “Disallowed Cost,” as the Contractor failed to “give an early warning which the contract required it to give” – hence, the assessment of the compensation event is £0.00.",

      "verbatim_quote": "Clause 16 contains a hallmark feature of the NEC - the ‘early warning mechanism’: either the project manager or the contractor can instruct the other to attend a risk reduction meeting and the employer can also be asked to attend. The purpose of the meeting is to discuss impact on time, cost and the works themselves.",
