60.3. Except for sections 42, 43 to 45.3, 46 and 47 and the third paragraph of section 48, and unless the context indicates otherwise, the provisions of this Act which concern a collective agreement or the application thereof apply, with the necessary modifications to a special agreement. Such an agreement may not be made, however, after a first call for tenders has been made for the carrying out of construction work relating to the major construction project.
If, on the date a special agreement is filed under section 48, there is a collective agreement applicable in the sector concerned by the special agreement, the special agreement becomes a schedule to that collective agreement. Otherwise, the special agreement becomes a collective agreement of limited application until a collective agreement takes effect in the sector concerned, in which case the special agreement becomes a schedule to that collective agreement.
The application of the clauses of a special agreement is limited, for the period determined therein, to the employees and employers who carry out construction work or cause construction work to be carried out as part of the major construction project to which the agreement pertains.
