• Prepare and negotiate change orders and contract modifications in accordance with public infrastructure contract requirements
• Review and approve submittals, shop drawings, lift plans, and engineered marine work plans
• Support pursuit efforts including bid reviews, quantity takeoffs, pricing strategy, and risk evaluation
• Interface with public agencies including DOTs, USACE, rail authorities, port authorities, and municipal owners
• Travel to active marine construction job sites up to 75% of the time as required
