However, the Contractor's risk of being later is, in simple terms doubled, as it has two paths of operations which could cause a further planned Completion to go back as opposed to the original one. Consequently, under clause 63.6 (NEC3) / 63.7 (NEC4) the Contractor is entitled to some additional time &/or monies due to the increased risk.
