Delve Underground Engineering PLLC

City-funded organization

Delve Underground Engineering PLLC is a tunnel design and heavy civil engineering firm serving the transportation, water, wastewater, and energy sectors. Per trade press, it was founded in 1954 as Jacobs Associates, later became McMillen Jacobs Associates, and took its current name and structure in a December 2022 rebrand that split the firm's underground and water-resources practices into separate companies. It holds 3 active NYC contracts worth $85 million, all with the Department of Environmental Protection since 2021, with $8 million paid to date. 87% of contract value ($74 million across 2 contracts) was awarded without a fresh competitive bid: a $59 million contract for design and settlement monitoring on the RWBT Bypass Tunnel and a $15 million Roseton General Monitoring Services contract, both badged as negotiated contracts on Checkbook NYC. Its third contract, an $11 million preliminary and final design contract, was awarded via RFP.
