This document provides information on the building services systems for a proposed double-storey school building, including electrical, water, sewerage/sanitary, and rainwater/surface drainage systems. Regulations and components for each system are described, along with drawings of proposed layouts. The project aims to demonstrate understanding of applying appropriate building services solutions based on practical considerations and compliance with local building codes.

3. Introduction
This project aims to provide us with an opportunity to develop knowledge
towards building services systems to be applied into proposing an
appropriate solution for the building services for our individual Architecture
Design Studio IV building design.
We this project, we are to demonstrate an understanding of the applicability
of specific building services systems in the design in response to practical
considerations as well on our ability to resolve issues that arise from each
building service system.
My building is a double storey building. The spaces are listed as followed.
Ground Floor Level:-
i) Lobby
ii) Library
iii) Play / Reading Area
iv) Outdoor Deck
v) Toilet
FirstFloor Level:-
i) Teachers Room
ii) Principles Office
iii) Balcony
iv) Roof Garden

8. Water Meter A device used to measure the
volume of water used by the
buildings that are supplied with
water by public water supply
system.
Stop Cock Used to control the flow of tap
water in services. It can be found
at the junction of a water main
and the branch leading to an
individual service, also inside the
structure, and are employed
when maintenance or emergency
repairs are conducted.
Gate Valve Gate valves are used to control
and prevent the flow of liquids.
Water Tank A storage unit that stores water
for distribution through a water
supply system
Galvanized Iron Pipe Galvanized Iron Pipe are used for
conveying raw water and
distribution of treated water in
majority or rural water schemes.

10. Floor Trap A plumbing fixture that is installed
on the floor of a structure for
removing any standing water
near it. The floor around the trap
is also sloped to allow the water
to be directed to the drain.
Man Hole An opening to an underground
utility vault that used to house an
access point for making
connections, inspection,valve
adjustments or performing
maintenance on underground
and buried public utility.

Conclusion
The process of this journal has helped me in obtaining an
understanding and knowledge based on the building services that is
applied in building designs considerations to help provide a better
proposal for the services intended for the proposed building.
In order to incorporate building services better with the design of the
school, following the uniform building by-laws and restrictions by the
local authorities helped creating a successful building design. There
are several topic in this proposal which comprises of rainwater
harvesting, stormwater management, electrical supply system, water
supply supply system and sewerage management.
The project guided me on how to make use of relevant information
that related to water system, electrical supply system, rainwater
harvesting, stormwater management, sanitary management and also
with better use of drawing conventions for various type of building
services system.
