6. ACCESS POINTS & SECURITY :
Proposed appropriate access points for office tower, commercial,auditorium and others, taking consideration of security, public and services.
Access control is to provide selective restriction of access to the building. It is important especially for a mixed development as in this project
due to the various groups of occupants or tenants that frequently enters and exits the premises.
Office Tower (Private)
Access control :
• Proposing 3 points of control access.
• First Point - access is controlled at the main entrance lobby (Ground floor) where the access key card is needed for office tenants or by visitor
registration (at information counter)
• Second point - access card only provides access to designated levels within the lift
• Third point - due to different type of tenancy per floor, each tenants needed to use the access card or password to access into their own
designated unit of office space through front point system.
Security System:
• to allow inter-communication between lobby ans office unit without direct access
• Combination of active security system such as motion sensors and CCTV on common areas, as well as proper for defensible space to allow for
visual surveillance of all areas such as corridor or foyer.

Note : Water demand is calculated in accordance to SPAN guideline.
Based on the water demand table :
The proposed water demand is 217,942 gallons per day for office tower, commercial & others.
Equivalent to 372 cubic metres DWT (Office Tower) x 2 days capacity = 744m, and 453 cubic metres DWT (Commercial & others) x 2 days capacity = 906m
Proposed storage capacity :
Storage capacity for Office Tower
= 12m (length) x 11m(width) x 3m (height)
= 396m3 - 372m3
Location
= Roof Top Level
Proposed storage capacity :
Storage capacity for commercial & others
= 13m (length) x 12m(width) x 3m (height)
= 468m3 -453m3
Location
= 4th Floor Roof

9. PROPOSED RWHT & OSD TANK :
The RWHT is proposed to be located at the podium level for irrigation usage and brak tank is located at level 17. The OSD tank is proposed at the basement
level before being discharge.

Proposed RWDP (Rainwater Downpipe) quantity :
Based on the roof cathment area which is estimated at 900m2
Estimated 1 downpipe of 100mm every 47 m2 and not more
than 12m apart.
= 900m2 / 47 m2
= 19 nos of downpipe required.
- 25 nos provided for better efficiency.

10. SOLID WASTE DISPOSAL :
The refuse chamber is located at the back lane beside loading bay.
• The proposed method of storage
type is sprial waste bin with a
capacity of 8.2m3 for the
commercial usage. Model type
SWB-8.
• The proposed method of storage
type is spiral waste bin with a
capacity of 16m3 for the office
tower usage. Model type SWB-
16D
• The chamber are to be located in
gorund floor beside the loading
bay away from the main
entrances and lobbies to avoid
having it visible to the public.
• There will be on allocated bulky
waste room that contains a ro-ro
bin.

11. AIR CONDITIONING SYSTEM:
ACMV SYSTEMS
Proposed of the air-conditioning system fo the office tower, commercial and others.
The proposed air conditioning system for office, auditorium and retails is centralized air conditioning system because:
.
• Ideal for large areas of a building where split units do not have the capacity to cool such a large area efficiently.
• it makes less noise. The condeser, fan and compressor are located in an outdoor unit, instead of in a nearby window, indoor noise is barely detectable.
• It is possible for specialized central air conditioners to operate in a reversed cycle, heat pump, to not only cool air, but also pump out hot air. The same
central air system can heat and cool the home in one user freindly unit.
Centralized unit sned cool air directly through air ducts or vents located in each room. Each room can be cooled instead of cooling just one room. Ambient
air is pulled into the air handler unit from each room through return air ducts. The system filters the air that passes through it, removing airbone particles.
Filtered air ais then re-routed back to the room via a separated ductwork system.

17. BUILDING MAINTENANCE SYSTEM
Proposed building maintenance system for the office tower.
In the selected project of a office tower, the external of building maintenance
include the following aspects:
• Electrical system
• Lift or vertical transportation
• Plumbing system
• Structural Integrity
• Building Envelope
The building envelope is crucial to be maintain frequently. The overall height and
slender profile of tower block requires proper maintenance units to be installed. As
such, a building maintenance unit is proposed for the purpos of upkeeping the
exterior of the building. The Building Maintenance Unit, or BMU, is the best
solution for the tall and uniquely designed tower. They are to be installed on the
main roof on a track system due to the regular form of the roof plan. Telescopic
booms will assist in providing an ontput 0f 130 feet to reach the areas of
difficulty.This system completely eliminates the need for support equipment, such
as sockets and davits, on lower roofts or balconies.
