PREFACE
In the career of building and protecting country, building and industrial construction are
essential contributing important roles. Along with the national continuous development in
the past years, fields of capital construction generally and civil engineering construction
in particular have invested by Government and Party and had deservedly proud
achievements. In the next years, in order to implement the career of modernization and
industrialization, building and industrial construction must precede a step, serve
purposes of socio-economic development.
In the recent years, the government is investing much in building and industrial
construction; advanced constructing technologies are applied in Vietnam. To apply in
fact, civil engineers level must be better and better. To satisfy demands of development,
The National University of Civil Engineering (NUCE) is opening scope and raising
quality of training.
After learning and gathering knowledge in the National University of Civil Engineering
(NUCE), now I designed a graduation project about the steel structure workshop. I am
guided directly by Dr. Vu Anh Tuan in Department of timber and steel structure and
Msc. Cao Tuan Anh in Division of Construction Technology and Management. I
sincerely thank the lectures of the subject, especially Dr. Vu Anh Tuan and Msc. Cao
Tuan Anh.
Beside, I also thank to my family and friends who gived me lots of help during I did my
project.
I tried to do my project best with my knowledge, but it is not very good because of time
and some other reasons. I hope advices, remarks and suggestions of teachers and all of
you.
Thank to you sincerely

GENERAL
In the recent years, Vietnam’s economy has changed dramatically along with the rapid
growth of the other countries in Asia. The reconstruction and construction of
infrastructure is needed in the open door period. On the other hand, the demand of
housing is very necessary to resolve land issues as well as changing the urban landscape
to deserve with the stature of a large city.
Ha Noi is the capital of Viet Nam. This capital has been center of political, economy,
culture, education and entertainment of the country. Ha Noi capital with approximate 6.6
million in population. The land of the city is now depleted while the demand of land for
business is increasing. Therefore, the construction of a high-rise building that combines
both commercial and leasing agencies is essential and appropriate to deal with those
above issues. Because of these reasons, the “CT2 Apartment” is licensed to build.

1.1. Floor plan idea
Solution condominium space research aimed at the average income, so the functional
organization plan toward affordable investment, saving up energy use in buildings, then,
competitive pricing in the marketing is better than neighboring buildings, the solution
include:
The aim is that the naturally ventilated and naturaly light is in all the rooms. The floor
plan is created as the I-shaped, corridor is along between the blocks. There is 3 unit in
each floor and 1 groups of lift, stairs is convenient transportation and safety fire
protection in accordance with current building codes to each apartment.
Entrance located between maximizing the size of the room with outside space.
Because of the Vietnam climatic conditions and Vietnamses inhabition, the layout of the
plan is very important, It affects in habit population in the appartment, so there is the
studies spatial for the layout of apartments. It is hot in summer and cold in the winter
cold, especially in the spring air humidity high and there are very few sunny days this
season, so the bedroom is layout to ensure natural ventilation, the naturally ventilation is

always the first concern. The most bedroom of unit is taken away, on alternating vertical
combination is the logia which the aim of creating a microclimate environment, limiting
the impact adverse climate for apartments. Living rooms are adjacent to the open space
outside and connected to the kitchen area, directly to logia which create perfect unit. On
the other hand, The investor in air conditioner is in the logia This is also where the heat
of the air conditioning system, helping to form architectural aesthetic worth.
Function of each floor:
Basement:
Basement area is used for parking area, security room, storage, electrical technical room,

TECHNICAL AND INFRASTRUCTURE SOLUTION

1.1. Ventilation solution.
Ventilation is one of the most important requirements in architectural design to ensure
hygiene and health for people to work and rest.
In general, the whole project is in the airy, spacious areas, ensure sanitation distance with
other houses. Hence, it also ensured ventilation requirements of the house.
In detail, the apartment is ventilated directly and arranged holes door, corridors and
cross-ventilated room.
On the other hand, because all side of the building are adjacent with available land, so
the solution is natural ventilation.
Overall, the layout must ensure ventilation and natural light.
Based on the using feature and requirements of sanitation, ventilation for each area, the
high of each floor is selected as the following:
- Basement elevation: 0.00m.
- Ground floor elevation : +3.20m.
- 1st floor elevation: +6.40m.
- 2nd floor elevation: +9.60m.
- 3rd floor elevation: +12.80m.

- 4th floor elevation: +16.00m.
- 5th floor elevation: +19.20m.
- 6th floor elevation: +22.40m.
- Terrace elevation: +24.90m.
- Roof floor elevation: +26.40m.
1.1. Lighting solution
According to artificial lighting standard for civil building (TCXD 16-1986), the building
was designed with many windows. Hence, all room can get sufficient light.
Central air condition is arranged on the technical floor.
Combining both natural light and artificial lighting.
Indoor lighting systems are designed by lighting standards (TCXD 16: 1986).

Lighting in the apartment, halls use fluorescent lamps; lighting in hallways, lobby use
150mm down-light lamps or compact bulbs; lighting in other areas such as stairs,
garages, warehouses, the WC… mainly used incandescent bulbs, ensuring minimum
illuminance in the region.
The exit light (EXIT) are located in all the aisles and main entrance of the house such as
the lobby, stairs, corridors and some other public areas.
Lamps of the stairs escape are controlled centralized power in the cabinet room.
Electric lighting system is protected by a system of Circuit Breaker installation in
electrical controller, lighting control switches mounted on the wall next to the door or
walkway, in the most favorable position.
1.1. Traffic solution
According to vertical direction: including 2 core systems in the center 2.4mx2.4m with 2
elevators to serve internal traffic, transport goods. The systems of elevator and staircase

are arranged at the center of the building. Hence it is convenient when moving and
exiting when happening fire.
According horizontal direction: corridors are designed from the vertical traffic spot.
Hence it is convenient to move around floors
1.1. The solution of water supply
1.1.1. Scope of works
The scope of the design of water supply system includes the following parts:
Cold water supply system including the connection point to the city water supply
network, water tanks, pumps, valves, piping of the whole project.
Hot water design local for each apartment, include bathroom and kitchen.
The drainage water after going through the septic tank will be discharged into the sewer
network in the city.
Vent pipe will connect with sanitary sewer drain grey, sanitary sewer drain black and
sanitary equipment. The septic tank have a vent pipe privite.
The septic tank will be designed to treat all wastewater from the toilets, kitchen of the
building before escaping into the city sewer.
Plumbing system includes:
- Drainage system.
- Water supply system.
- Storm-water drainage.
1.1.1. Design parameter
Calculate rainfall intensity: 484.6 l/s-ha = 174 mm/h.

Velocity in vertical pipes and water main pipe supplying water from1.5 to 2m/s.
Velocity water flowing in the branch pipe water supply to2.5m/s.

The minimum hydrostatic pressure of the water supply system is150kPa (1,5bar).
The maximum hydrostatic pressure of the water supply system is600kPa (6,0bar).
Criteria for water supply: 200 lít/person/day (for apartment)
Criteria for drainage: 100% Criteria for water supply
1.1.1. Cold water supply system
Water supply for domestic demand of condominiumis supply from the water supply
system of urban. Water supply underground tank pass float valve. From underground
tank use transport pump (1 activities, 1 preventive) have capacity Q= 13m3/h – H=45m
forward domestic water tank on the roof floor after supply equipment use water of
condominiums.
Underground tank include water for fire fighting and for living and a tank on the roof
floor each tank. Underground water tanks constructed of reinforced concrete
underground inside the building. Rooftop water tanks using GRP tank assembly. The tank
is divided into compartments for ease of washing.
Water supply pipes using polypropylene (PP-R) pipes for cold and hot water supply.
All the cold water pipe in the house (except water supply pipe from the pump to the tank
roof) over pressure is 10bar.
Hot water pipe and water supply pipe from the pump to the tank roof over pressure is
20bar.
All pipes come in ceiling, in wall or in technical boxs.
Water supply section will be combined with the following items:
Install valves for sanitary equipment groups.
Waterproof devices and pressure relief valves installed at the boundary points of the
water supply.
Water supplying system: Water is supplies by water supplying system of the city and
contain in underground water tanks of the building. Water follow is controled by gauges.
After that, water is pumped by pumps system and contained in roof water tanks. Water is
supplied to restrooms of building by water pipe system from roof water tank
automatically. Pipe system is hidden in floors, walls and technical boxes.
1.1.1. Hot-water supply system

Hot water system will be designed for the toilet and kitchen of the apartment. Water
heater types and capacities may be used for this project.
