NS 8405 Chapter II “Contractor's benefits” contains eight provisions that impose requirements on the contractor during the construction phase.
NS 8407 also has such provisions collected in Chapter IV “The performance of work by the general contractor under the contract”. In addition, a few provisions concerning transport (paragraphs 12 and 13) and the use of contract assistants (paragraph 10) have been added to Chapter II.
Although NS 8406 has a simpler structure without chapter division, this standard also contains provisions on most of the topics such as NS 8405 and NS 8407. Exceptions are provision for transportation and contractor engineering.
As before, we start from NS 8407 since this is the contract standard that is used most often today.
