Indiana Code Title 4. State Offices and Administration § 4-13.6-6-4

Sec. 4. (a) Within sixty (60) days from the date on which bids are opened, the division shall award a contract and shall provide the successful contractor with written notice to proceed.

(b) If the division fails to award and execute a contract and to issue notice to proceed within sixty (60) days that bids for the contract are opened, the successful contractor may grant one (1) or more extensions of time to the division to award a contract, to execute the contract, and to give notice to proceed. The date that an extension of time granted under this subsection expires must be a date upon which the division and the successful contractor agree.

(c) After the sixty (60) day period set by subsection (a) and all extension periods set under subsection (b) have expired, a successful contractor may elect to withdraw its bid and reject the contract only by delivering a written notice to the division that grants the division at least fifteen (15) additional days to award a contract to the successful contractor.
