This role is ideal for someone with early estimating experience or a background in field operations who’s ready to contribute to meaningful infrastructure work. You’ll focus specifically on the mechanical scopes tied to civil systems—buried piping, wet utility connections, pump stations, tank infrastructure, and more.

Key Responsibilities

• Support the estimating team in preparing accurate bids for mechanical scopes including piping systems, pump stations, tanks, and associated appurtenances

• Perform detailed quantity takeoffs for buried utilities, large valves, and mechanical components from plans and specs

• Help evaluate bid documents, plans, and addenda to identify scope requirements, clarifications, and risks

• Assist in soliciting and organizing quotes from vendors and subcontractors for mechanical materials and services

• Attend job walks and pre-bid meetings to gather site-specific data

• Help prepare bid packages, internal review documents, and pricing summaries

• Work closely with the estimating and operations team to review constructability and labor productivity

• Maintain and update cost history and material pricing databases for mechanical work

• Contribute to project handoff documentation to field and project teams after award

• Wastewater and water treatment facility mechanical packages

• Pump stations, lift stations, and tank installations

• Buried mechanical piping systems (water/sewer/storm)

• Large valve and vault installations

• Civil utility improvements with integrated mechanical scopes

Qualifications

• 1–3 years of estimating experience in mechanical or heavy civil construction OR hands-on project support background (field/engineering)

• Ability to interpret detailed civil/mechanical drawings and project specs

• Familiarity with piping layouts, mechanical vaults, valve schedules, and tank systems

• Strong Excel skills; exposure to estimating tools such as On-Screen Takeoff, Bluebeam, or HCSS is a plus

• Eagerness to learn in a collaborative environment and contribute to a high-performing estimating team

• Union labor or prevailing wage project experience is a plus

• Field or trade experience in plumbing/mechanical scopes beneficial

Compensation & Benefits

• Competitive salary based on experience
