1.0 INTRODUCTION
Project 2 is an individual assignment on the application of basic building services to a domestic
sized building. This exercise requires us to demonstrate our understanding on the application
of such systems by producing technical drawings of the necessary services.
The focus of this project revolves around the application of necessary building service systems
to domestic sized buildings. The project calls for the thorough understanding of the planning
process, installation, and application of service systems, including electrical supply, sewerage,
drainage, and water supply systems.
The objective of this project is to enhance the understanding of the applications and challenges
with regards to building services beyond what is taught in lectures. This is achieved by the task
of applying appropriate building systems, with consideration of UBBL guidelines for a given
design.
This report compiles relevant information related to water and electrical supply, liquid waste
disposal, sanitary and rainwater management system and propose the most suitable systems
for a specific type of building.
Students are required to apply building services schematics to their design studio project for
the application of the building services systems. Drawings are to be produced to show the
correct application of the services, including on the site plan, building plans and roof plan. The
drawings must be reproduced into a computer aided drawing with annotations which describe
the planning and installation of all building services required.

4.2.4 COP 07, Requirement of earthing system
The primary requirement of the earthing system is to ensure effective operation of the circuit
protective device. For effective operation of the circuit protective device, the resistance of the
earthing system shall be as low as possible. In installations where RCDs are used as the circuit
protective device, earthing resistance of less than 10 Ω will generally ensure effective operation
of the RCDs. However earthing resistance of less than 1 Ω is the target.
4.6.9 COP 28, Cables installed behind walls
Where cables are installed buried behind walls, they shall be installed horizontally or vertically
i.e. parallel to the edges of the room. Subject to the dimensions of the columns and beams,
they shall be within 150 mm from the top of the walls and 150 mm from the edge of the wall.
4.6.10 COP 29, Mechanical protection for cables within walls
Cables installed within walls shall be provided with mechanical protection such as a conduit.
Direct installation of cables within walls is not allowed.
4.6.11 COP 30, Cables installed within ceiling space
Where cables are installed behind suspended ceilings or the ceiling space under the roof,
they shall be provided with mechanical protection such as being installed within approved
conduits. In addition they shall be installed either parallel or perpendicular to the edges of the
walls.
4.6.13 COP 32, Air conditioner circuits
A circuit intended to supply an air conditioner shall have a socket outlet (an unswitched type
is acceptable) in the vicinity of the air conditioner to facilitate the connection of the circuit to
the apparatus and to facilitate disconnection during maintenance.

2.3 SEWERAGE AND SANITARY SYSTEM
1. Floor Trap
A floor trap is a drainage fixture on the floor
of a room, commonly in bathrooms to
channel out standing water near it to avoid
flooding. The floor around the drain needs to
be slightly sloped to allow water to flow to the
drain by gravity.
2. Manhole
A manhole is the top opening to an
underground utility vault used to house an
access point for making connections,
inspection, valve adjustments or performing
maintenance on underground and buried
public utility.
3. Vent Cowl
A cowl is a usually hood-shaped covering
connected to the sanitary services in a
building, to exhaust odors coming from the
system and prevent backflow.
4. Gully Trap
A gully trap is a basin in the ground which
receives piped wastewater before it is
emptied into the sewer. The basin has a
water seal to prevent foul odors from the
sewer to reach the surface.
5. P-Trap
Similar to a gully trap, a P-trap is installed
under sinks in bathrooms and kitchens stops
sewer gases from passing into the home.

4.0 CONCLUSION
The project has allowed the student to observe and appreciate small details in the
implementation of building services, something usually taken for granted. Students are sure to
gain immense knowledge on the mechanism of each category of service while at the same
time gaining a newfound appreciation towards the importance of building services in our daily
lives. This project has also given a first hand look at the applications of the theories we learned
in the classroom.
6 detailed drawings (including diagrams) have been produced in completing the project. The
diagram produced increases the appreciation of these systems that are often taken for granted.
I would like to thank both Ar. Sateerah and Mr. Azim for carefully designing this module and
projects, as well as passionately guiding the students along the way towards the completion of
the module.
