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

2. Concept Design Satisfy clients key
success criteria Comply with the
current statutory legislation Eg. Building
regulation
3.Design Brief Clarification:
future scope of services, actual scope of work, design deliverables, unique project requirements
Confirmation: technical basis, design standards
4.Scheme Design Stage Producing and
analyzing the design to get the desired result
If its not satisfying, its being revise
Process of Drawings
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
