• Review mechanical/HVAC design documents, calculations, and submittals for completeness, constructability, and alignment with Government requirements; provide written comments and recommended resolutions. • Support facility condition assessments by evaluating mechanical systems documentation, identifying deficiencies, and drafting recommended corrective actions. • Perform technical research and analysis related to HVAC performance, ventilation, energy efficiency, and indoor air quality; document findings for Government consideration. • Develop and/or review equipment schedules, sequence of operations narratives, and engineering options analyses to support Government evaluation. • Draft technical inputs for Statements of Work, performance requirements, acceptance criteria, and evaluation factors for Government review and approval. • Coordinate with architectural and other engineering disciplines to identify interfaces (e.g., power, controls, space constraints) and integration issues. • Support commissioning and closeout documentation reviews (as applicable), including verification checklists and deficiency tracking. • Prepare technical briefings, decision-support matrices, and executive summaries for Government stakeholders.
