Create and build mechanical devices.

Mainly with HVAC or machine design.

HVAC – Heating, ventilation & air-conditioning

Machine design: on hardware, including automobile engines, computers, and washing machines.

What is Mechanical Engineering?

Deals with the technology of electricity.

Electrical engineers work on components, devices and systems such as microchips and power station generators.

Examples: Security system, lighting point, electrical substation.

What is Electrical Engineering?

Client comes out with conceptual brief. Architect provide schematic design. Meeting consist of:

Client’s managerArchitectCivil and Structure engineer (C&S)Mechanical and Electrical engineer (M&E)Quantity Surveyor (QS) Landscape Architect Interior DesignerAcoustic consultantEnvironmental consultant

PROCESS OF A PROJECT

C&S engineer design road and drainage, retaining wall, sewerage.

C&S engineer designs the frame of building by coordinating with the M&E engineer.

Building plan ready and submitted to local authority for approval.

QS prepare the bill of quantity to incorporate the requirements in the tender documentation.

M&E engineer prepares the schedule of prices for tenderer.

Tenderer issues the tender documents and drawings

analyse the given documents before construction process starts.

Constructions can be started after appointing a contractor.

Site meetings

to discuss details of the process such as Clarification and suitable ways for installation.

Testing and Commissioning:

Check, inspect and test project component.

C.C.C (Certificate of Completion Compliance) is issued

Roles of Mechanical & Electrical Engineers in construction:

PRE-CONSTRUCTION

Analyze arcitect’s drawings

Advise client the suitability and appropriateness of the equipment

Incorporate their respective requirements into architecture drawing

Eg. Location of AC, types of lifts, fire system layout

DURING CONSTRUCTION Supervise the process of

construction. To ensure there is no error in

the process of construction.

POST CONSTRUCTION Operation and manual

documentation Test and commissioning Maintenance

To ensure safety of end user

6. Construction Design Information Detail drawings

are used to facilitate during the construction process

7. Construction Process of building

8. Design Feedback To improve

current and future projects

Benefits: Ensuring a better understanding of client’s requirements

5. Detail Design Stage Specific calculation is

implemented into the drawings

Eg. Pipework, electrical load, smoke extract ventilation, energy consumption
