The NSSP is a step in the right direction because it will reduce emissions due to construction ion by reducing milling time and hauling away cuttings from the milling.
It will also lead to better rehabilitated highways.
The specification requires the contractor to perform surveying and design prior to undertaking milling. These activities require time during the contract. The amount of time is a function of the highway complexity, 2 lane rural hwy, 4 lane divided highway urban or rural freeway with interchanges etc.
Designers and the Ministry must recognize that the survey and design requirements will inherently add time to the duration of the contract. The additional time must be considered when determining contract working days or completion dated as well as the actual advertising and award dates. The notes to designers should include this comment.
