  • Commercial construction estimating experience with a General Contractor or Construction Management firm.
  • Strong understanding of construction documents, scopes of work, subcontractor pricing, and project costs.
  • Ability to manage multiple estimates and deadlines in a fast-paced environment.
  • Strong analytical, organizational, and problem-solving skills.
  • Excellent communication and interpersonal skills.
  • Ability to develop and maintain strong subcontractor and vendor relationships.
  • Bachelor's degree in Construction Management, Engineering, or a related field preferred, or equivalent industry experience.
  • Self-motivated, detail-oriented, and committed to delivering accurate, high-quality work.
