The board may, upon approval of the application, in whole or in part, and subsequently from time to time, make a conditional apportionment or conditional apportionments not exceeding in the aggregate the total amount approved for the application from the State School Building Aid Fund for such portion or portions of the project for which the board determines the district is ready to proceed. If the board has approved an application and made an apportionment as to a portion or portions of a project, the board may approve the remaining portion or portions of the
project and make an additional apportionment or apportionments as it deems appropriate.
If the board determines that the actual cost is in excess of the estimated cost of the specific school plant facilities or sites for which an apportionment to a district has been made, or for which a district’s application has been approved in whole or in part pursuant to this section, the board may make an additional apportionment to any district in an amount equal to the excess even though the additional apportionment will result in the total apportionments to the district exceeding the amount of the application originally approved by the board.
Approval of an application under this section shall not be construed as creating or implying any obligation, commitment or promise on the part of the board or the state to make apportionments under this chapter.
