• Solicit, analyze, and scope subcontractor and vendor proposals to ensure accuracy and coverage.
• Collaborate with design partners to align design development with cost and constructability considerations.
• Support the development of pricing models, cost summaries, and GMP or target price proposals.
• Participate in design and value engineering sessions, providing cost-driven feedback.
• Assist with client presentations and internal preconstruction deliverables.
  

Qualifications

• Bachelor’s degree in Construction Management, Civil/Environmental Engineering, or related field (or equivalent experience).
• 3–8 years of estimating or project management experience, preferably in water/wastewater treatment.
• Experience in collaborative delivery projects (CMAR, DB, or PDB) strongly preferred.
• Proficiency with estimating tools such as InEight; strong Excel and quantity takeoff skills.
• Familiarity with Bluebeam, Revit, or Navisworks a plus.
• Understanding of treatment process systems, mechanical/electrical components, and construction sequencing.

• Collaborative and team-oriented approach to problem-solving.
• Strong communication and organizational skills.
• Detail-driven with the ability to manage multiple priorities in a fast-paced environment.
• Eagerness to learn and grow in preconstruction for complex water infrastructure projects.
