Minor Project- Less than $750,000, not STIP or SHOPP. In California, minor capital outlay consists of construction projects or equipment acquired to complete a construction project estimated to cost less than $750,000. The California Transportation Commission allocates a fiscal year level for this category with specific project allocation approval delegated to the Department. Minor is further segregated into two categories: Minor A – Minor construction projects with an estimated contract value between $117K – $750K. Minor B – Minor construction projects with an estimated value less than $117,000.
