Draftsman Mechanical Engineer

Purpose To support the design and project teams by producing accurate HVAC drawings including ductwork, VRV systems, RCP layouts, and detailed sections. The draughtsman ensures precise site-based coordination

with other services, contributes to BOQ preparation, and provides

drawing documentation necessary for consultant approvals,

fabrication, and on-site execution.

Role and Responsibilities

1 HVAC Design & Drafting

Design and detail complete HVAC systems including duct layouts with airflow and pressure considerations.

Create zoning layouts for efficient air distribution and temperature

control.

2 As-Built & Section Drawings As Per Site Mark-Up and Against Physical Verification at Site.

Prepare and update As-Built drawings reflecting actual site

implementation.

Develop detailed sectional drawings to assist in installation and

compliance.

3 BOQ & Estimation Support

Generate accurate Bills of Quantities (BOQs) for HVAC systems to

support estimation and procurement.

4 RCP & Room Data Integration

Create Reflected Ceiling Plans (RCPs) incorporating HEPA filters,

risers, light fixtures, diffusers, and grilles based on room data sheets.

5 Detail Drawing DevelopmentProduce typical HVAC detail drawings including:HEPA units, duct constructions, heater plenumsVolume and fire dampers, switches, socketsGrilles/diffusers, and Magnehelic

gauge locations

6 VRV System & Drain Layouts

Develop piping layouts for VRV systems and associated condensate

drain systems.

7 Client & Consultant Coordination

Attend client and consultant meetings to review drawings, gather

feedback, and implement technical revisions.

8 Site Measurement & Validation

Conduct on-site measurements for HVAC and related systems to

verify layout accuracy and adjust drawings accordingly.

9 Multidisciplinary Coordination

Coordinate HVAC layout with electrical, cleanroom partitions, and

other MEP services to avoid clashes.

10 Fabrication Drawing Preparation Review

Create fabrication-ready drawings for ducting systems and cleanroom elements with accurate quantification and measurements for

approval.
