You can construct or upgrade several facilities simultaneously by using the Additional Construction Brigade item. The Additional Construction Brigade item can last for 24 hours, 7 days or 30 days. You can only obtain this item as a Special Offer from the Bank.

Please note: If you activate several Additional Construction Brigade items, the number of Additional Construction Brigade items you have will not increase. Instead, the time remaining on the first item will be extended. For example, you have an Additional Construction Brigade activated for 24 hours and it has not yet expired, then activating an Additional Construction Brigade for 7 days means that the total time for the Additional Construction Brigade item will be 8 days. The number of items will, however, remain the same.
