Restricted Working/Access Compensation Event Entitlement

Working under an NEC4 Option E contract; we have had a situation where a small part of the site has been taken over by a third party for works, and subsequently handed back. During this time, access to that part of the site was restricted but works have continued in the main site area; the only impact was to the size of plant able to be used and some early material deliveries. We have accepted a CE for the restricted working under 60.1(2). The Contractor has submitted a quotation for the entire duration of the restricted access, although works continued largely uninterrupted. Am I right in saying under 63.5 we would only pay for the time impact of the event itself, e.g. an allowance for the slower working due to plant and material restrictions, not the full duration the restriction was in place?
