• Establish HVAC control philosophy write-up, cause and effect analysis, develop alarm list and interlock mechanism.

2. Mechanical System Design:

• Establish process utility design following customer’s tools matrix summary, such as CDA, Vacuum, PCW, Steam, Exhaust, Drain, Specialty Gas, RODI, WWTP and etc
• Develop process utility P&ID and piping/ducting layout.
• Develop plant room space management study and services routing from plant room to production floor.
• Calculate mechanical load requirements and size components such utility pump/fan sizing, pipe/duct sizing, utility flow calculation.
• Establish process utility system control philosophy write-up, cause and effect analysis, develop alarm list and interlock mechanism.

3. Project Tendering:

• Review tender requirements, participate site visit, communicate with client to ensure the proposals meet client and project specifications.
• Develop concept dwg and equipment schedule to enhance vendor and supplier knowledge on tender specification and specific challenges.
• Participate tender costing exercise, support procurement team on proposal preparation.
• Support procurement team to evaluate vendor/supplier proposal qualification, materials/equipment selection, ensure proposed solution sound practicable and reasonable, meeting quality and regulatory compliance, adhere tender scope of work, delivery schedule, deviations and partial compliance element.
• Collaborate with vendors to improve competitive pricing for project tenders.

4. Project Management:

• Coordinate with clients, contractors, and project stakeholders to clarify requirements and resolve design-related issues.
• Conduct system design presentation to explain proposed design, equipment selection, comparison of different design approach, convince client’s doubt and persuade business decision.

5. Documentation:

• Prepare technical documents, includes MEP dwg, equipment schedule, RFQ/RFP, sub-contract work package specifications.
• Maintain accurate and up-to-date project files and records.

6. Collaboration:

• Work closely with the electrical, control, civil, and architectural teams to ensure seamless integration of HVAC and mechanical systems into overall project designs and execution.
• Review and evaluate supplier/vendor proposal, assist QS and project team on equipment selection and seek supplier/vendor clarification on design specification compliance and performance assurance.
