• Produce load calculations, equipment schedules, psychrometric analyses, pipe sizing, duct sizing and energy modelling reports.
• Prepare full mechanical drawing packages: layout plans, schematics, sections, riser diagrams, details and specifications.

• Coordinate mechanical systems with architectural, structural, electrical and plumbing disciplines to resolve clashes and optimize spatial integration.
• Review and approve MEP BIM models for coordination and clash detection using Navisworks or equivalent platforms.
• Prepare and review technical submittals, method statements, material approval requests (MARs) and shop drawings from contractors.
• Conduct engineering reviews against Saudi Building Code (SBC), ASHRAE, NFPA, BS and CIBSE standards.
• Perform energy compliance checks and sustainability assessments, including LEED WELL mechanical prerequisites.

• Carry out regular site inspections to verify mechanical installations comply with approved design drawings and specifications.
• Attend site coordination meetings, technical workshops and progress review sessions with contractors and clients.
• Review and respond to RFIs, technical queries and variation requests from the main contractor and subcontractors.
• Support commissioning and testing teams during system start‑up, balancing and performance verification stages.
• Prepare and review O&M manuals, as‑built drawings and handover documentation for final project close‑out.

• Manage mechanical design deliverable schedules and resource allocation across multiple concurrent projects.
• Liaise with Saudi Electricity Company (SEC), SASO, Civil Defense and municipal authorities for system approvals and NOCs.
• Lead client‑facing technical presentations, design workshops and value engineering reviews.
• Mentor junior and mid‑level mechanical engineers, fostering technical growth and quality standards across the team.
• Collaborate with commercial and project management teams to deliver within the agreed budget, scope and program.

• Bachelor’s Degree in Mechanical Engineering from a recognised, accredited institution.
• Minimum 12 years of post‑graduation professional experience in mechanical building services engineering.
