3. Who are Mechanical & Electrical
E n g i n e e r s ?
- work with architects and structural engineers.
- Instrumental part of the design team.
Sizing and layout of Heating Ventilation and Air
Conditioning (HVAC) , routing treated air and
design of lighting & communications system.

4. Mechanical Engineer provide solutions to development
of processes and products, ranging from small
component to extremely large plant, machinery or
vehicles.
[ construction industry : HVAC]
Scope of Work
Electrical Engineer work on
development of lighting and
communication systems.

5. Whatdo they do?

6. Before Construction
- Implementing cost-effective equipment modifications.
(help improve safety and reliability)
- Developing and evaluating theoretical designs.
- Research, analyze, planning (mathematical modeling ).
- Recommending modifications following prototype test
results. (Design & Experimenting )

7. During Construction
Monitoring and commissioning systems.
Direct and coordinate
manufacturing, construction,
installation and maintenance
activities.

8. After Construction
Make sure a system can function
again reliably and will perform
consistently in specified
operating environments.
Inspect complete installations and
observe operations, ensure operational
compliance (teamwork).
