Overview |
|
This
project consists of two blocks of 41-storey domestic New Harmony 1
Block, one block of 8-storey Standard 30-Classroom Primary School
(2000 Edition). The blocks contain 80 No. Type 3B, 880 No. Type 1B,
320 No. Type 2B, and 238 No. Type 1-2/P rental domestic units in 40
domestic upper floors. In addition, one 2-storey Automated Refuse
Collection System and Junk Collection Point Compound will serve all
residential blocks in Tseung Kwan O Area 73A by being connected to
Phases 1, 3 and 4 via chute laid under Estate Road and
surface-mounted against retaining wall. |

Wall System
|
|
Large
Panel Formwork is used to construct the structural walls of
the Harmony Blocks. It is a typical feature of housing
projects. The floor cycle is 6 days (Two days for larger
wings and one days for the smaller wings).

Slab
System |
|
|
|
Semi-precast
slab is adopted for the structural floor of the flats. A 70mm
precast slab serves as the formwork for a 90mm in-situ
concrete layer, thus forming a 160mm thick concrete floor.
This saves time in erecting and striking the timber formwork
as well as reduces the timber waste. |

Aluminium
formwork is used to construct the floor slab of the corridor
of Harmony Blocks. This is an innovative feature of the
project. The cost is even cheaper than that of timber
formwork. |

Precast
Facade |
|
This is also
a typical feature of the housing projects. The problem of
water leakage with this type of construction is primarily
dealt with by the overhanging toe of the whole pre-fab unit
which stops water penetration from the horizontal parts. The
vertical joint is formed by the built-in of facade into the
structure. |
|
|
|
Precast
Kitchen Facade |
|
Precast
kitchen facade with PVC openings for the drain pipes is an
innovative feature of the project. |
|
|
|
|
Precast
Bathroom |
|
Precast bathroom is also an
innovative feature of this project. The bathroom is prefabricated in
factory and transported to site as a whole. It is fixed to the
building structure with the help of tower crane.
