Related Party Transactions [Abstract] |
Related Party Transactions | Related Party Transactions The Company leases, at market rates, certain facilities from an entity owned by Ronald N. Tutor, the Company’s Chairman and Chief Executive Officer as of December 31, 2024, who subsequently transitioned to the role of Executive Chairman effective January 1, 2025. Under these leases, the Company paid $4.0 million in 2024, $3.9 million in 2023 and $3.8 million in 2022, and recognized expense of $2.4 million in 2024, $4.1 million in 2023 and $4.6 million in 2022. In addition, on November 4, 2022, the Company purchased a property from another entity owned by Mr. Tutor, which was developed into a new equipment yard to replace an equipment yard the Company leased from an entity owned by Mr. Tutor. The Company paid $4.1 million to purchase this property, which was the amount that Mr. Tutor paid to acquire the property from an unrelated third party shortly before the Company decided that it wanted to own and operate the property. At the time the new property was purchased, Mr. Tutor and the Company amended the existing equipment yard lease, which originally ran through July 2038, to expire earlier if the Company relocated to the new equipment yard and surrendered the leased yard back to the entity owned by Mr. Tutor. The existing equipment yard lease with the entity owned by Mr. Tutor expired pursuant to its terms on December 31, 2024 with no significant incremental costs expected to be incurred by the Company.
