Specialist HVAC&R Engineering Support, Shop Drawings & Mechanical Services Delivery for Contractors

MEP Engineering Co (MEPEC) is a specialist MEP engineering group providing high-level HVAC&R engineering, drafting, coordination, BIM modelling and construction-phase technical support to mechanical contractors across Australia.
MEPEC acts as an engineering extension of a contractor’s business, delivering shop drawings, mechanical documentation, load calculations, static-pressure assessments, plantroom layouts and BIM integration that enable HVAC contractors to complete complex mechanical projects efficiently, accurately and in accordance with Australian codes.

Their capability spans tendering, detailed design, coordination, workshop drawings and on-site set-out.

HVAC Shop Drawings & Detailed Mechanical Documentation

MEPEC produces complete mechanical shop drawings including:

• ductwork layouts
• pipework layouts
• riser detail and multi-services coordination
• plantroom arrangement drawings
• equipment schedules
• grille/diffuser layouts
• wall/roof penetrations & sleeve locations
• hanger and support layouts

These drawings are developed to minimise clashes, reduce RFIs and meet head-contractor BIM requirements.

Duct & Pipe Sizing, Fan Static & Pump Head Calculations

MEPEC provides essential mechanical calculations used by contractors during tendering, procurement and construction:

• SMACNA / AS 4254 duct sizing
• chilled water / condenser water / heating water pipe sizing
• fan static pressure calculations
• pump head calculations
• coil performance checking
• airflow balancing guidance

This helps contractors validate design, select compliant equipment and avoid mis-sized plant during construction.

Mechanical Plantroom & Roof Plant Coordination

MEPEC develops coordinated mechanical layouts for:

• central plantrooms
• rooftop mechanical plant
• risers
• equipment access & maintainability
• architectural and structural coordination
• spatial allocation for AHUs, pumps, heat exchangers, chillers and boilers

This ensures contractor installations are buildable, compliant and maintainable, avoiding costly redesign during installation.

BIM Modelling, Revit Integration & Multi-Trade Coordination

MEPEC delivers fully integrated BIM services for mechanical packages:

• Revit modelling of mechanical systems
• clash detection with structure, electrical, hydraulic and fire services
• coordination models for fabrication
• BIM exports for construction sequencing and set-out
• 3D coordination for design approval and consultant sign-off

For BIM-mandated projects, MEPEC ensures mechanical services integrate seamlessly into federated models.

Car Park Ventilation, CFD & Specialised Mechanical Systems

MEPEC provides specialised engineering support for:

• car park ventilation
• CFD simulations for performance solutions
• jet fan systems
• smoke exhaust and pressurisation
• AS 1668.1/1668.2 performance verification

These critical scopes require precise engineering and code alignment, making MEPEC a key support partner for contractors.

Equipment Selection, Scheduling & Value Engineering

MEPEC supports contractors by:

• verifying and selecting mechanical equipment
• comparing performance between options
• optimising FCUs, AHUs, VRF/VRV, heat exchangers and fans
• preparing equal-or-better alternatives
• delivering structured value engineering recommendations

This helps contractors maintain compliance while offering competitive project solutions.

On-Site Support: Set-Out, Coordination & Construction Assistance

MEPEC extends into construction support:

• site set-out
• robotic total station layout
• clash resolution during installation
• late design change analysis
• variation support
• commissioning documentation

This reduces risk, accelerates delivery and improves accuracy on demanding mechanical projects.
