However, the total value of contracts awarded for the additional construction services may not exceed 50 per cent of the amount of the main contract;(g) for new construction services consisting of the repetition of similar construction services which conform to a basic project for which an initial contract was awarded in accordance with Articles VII through XIV and for which the entity has indicated in the notice of intended procurement concerning the initial construction service, that limited tendering procedures might be used in awarding contracts for such new construction services;(h) for products purchased on a commodity market;(i) for purchases made under exceptionally advantageous conditions which only arise in the very short term.
