I hope advices, remarks and suggestions of teachers and all of you.Thank to you sincerely Ha Noi, June2016StudentNGUYEN XUAN TUNG PART IARCHITECTUREDrawing:•KT01 Elevation of the building.•KT02 Crosssection AA and BB of the building.•KT03 Ground and first floor plan.•KT04 3rd6th floor plan and roof plan. 1.GENERALIn 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 highrise 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. Figure I.1.

Layout reasonable apartments, to ensure sanitation, facilitate transportation and living.Architectural requirements: to aesthetic and consistend with the trend of social development. Consistend with the overall architecture of the building of new urban and local air. Take full advantage of ventilation and natural lighting, to ensure facilitate transportation, quick and safe escape and timely for people when the incident occurred.Design building include the basement to keep the car, the other floor layout household room, on the roof layout swimming pool and technical room.Building full layout transportation system in both horizontal and vertical to suited for traffic problems in the building.1.3.Climatic conditionThe building is located on Hoang Mai district, Ha Noi city. In which is typical for the northern climate, is characterized by tropical monsoon climate: hot summers and rainy, dry winters and less rain. Because of its location in the tropical monsoon climate to Hanoi to receive yearround solar radiation is abundant and high temperature. The amount of radiation a total annual average of Hanoi is 122,8kcalcm2 and the average air temperature annual is 23,6oC. Due to the influence of the sea, humidity, the average rainfall is quite large in Hanoi. The average relative humidity is 79% annually, the annual average rainfall is 1245mm per year and an average of 114 rainy days. From May to September is hot and rainy season (1682mm rainfall year), this time is often stormy, wind levels from level 8 to level 10 and sometimes up to level 12. From November to April next years later that is winter, dry weather. There have a transition period between the two seasons (April and October).Hanoi has 4 seasons: Spring, summer, fall, winter. There is sometime freezing temperatures down to the 2,70C (thang1 1955) and is the most intense heat with temperatures up to 42,80C in Hanoi (May 1926).The study area is dominated by the Hanoi climate is considered harsh with high moisture and high humidity, large amplitude, cool northeast monsoon. Beside, the last weather is good, the temperature and humidity in accordance with the average human comfort, cool southeast monsoon. The design architecture is exploited the advange and disadvanges of the weather.1.4.HydrogeologyBase on the Area Geological of Soviet Union (former) recorded at Hanoi Masterplaning Construction Institute, most studied area is located on the 2nd partition geology; is considered favorable level for construction. Structure from top to bottom is silty clay layer (thickness of 57 meters) plastic clay clay hard fightingplastic clay soft clay. A small section in the south lies on the third partition geology is not favorable assessment for construction. When implementing specific projects for geological exploration drilling in the study area to solution processing structure suitable foundation works.2.ARCHITECTUAL BRIEF2.1.Solution for master planning and elevationThe complex form is appartment with 7 floor in the center of project. The cover outer walls were painted and tiled to created special view for the project. Using architecture square columns with groove pattern, doors and windows glass door layout by arch steel frame combined with a balcony used to get light, ventilation and aesthetically created for the project. The combined idea with the medium height, the concrete segments and vintage ornamental pattern is used effectively not only the environment, but also healthy surroundings. The main idea illustrate that the living space is good orientation, environment and can view the scenery outside.The purpose of the project is to create an architecture simple and minimum to optimize the efficiency of land use and environmental conditions.The Serves Area of all the project is the space which combined with landscape garden, to create a master plan with high uniformity and harmony with landscape architecture.Vertical transportation included stair and elevatorProject is a high rise building. Its height is 26.4m with 7 floors, an attic and a roof with elevation: Ground floor elevation : 0.000m. 1st floor elevation: +3.2m. 2nd floor elevation: +6.40m. 3rd floor elevation: +9.60m. 4th floor elevation: +12.8m. 5th floor elevation: +16.0m. 6th floor elevation: +19.20m.

and signage Table for rebar fabrication must be fixed surely, fabricated rebar must put on right place When straightening steel roll by machine, have measures for covering cylinder and avoid rebar to slip to come out before operating Cable top of winch is connected to rebar which needs straightening by special equipment, only dismantle the connection when the winch off Forbid to use the engine for cutting steel segments shorter than 80 cm without the safety devices When the installation of reinforcement near power lines, must cut power off, if not, must take measures to prevent the reinforcement touching power line In Formwork and scaffold tasks During construction, using formworks or scaffolds must follow the design approved by authority Prohibit not to use scaffolding when: does not meet the technical requirements and safety conditions as inadequate anchor hook, ligaments or they are anchored to the parts having poor structural stability Do not use the scaffold or formwork when they are deformed, cracked, and shores when they are placed on which are unstable or likely to slip or structural components not being calculated bearing capacity yet When the erection of scaffolding systems, need to the following: anchor the scaffolds firmly to the building and the location of the anchor hook should be set according to the design When the anchor hook position coincides with the hole in the wall, have to make bracing inside to anchor Dismantling formwork must proceed in sequence and according to the instructions in the design The dismantling area must be fenced to prevent people or vehicles go through Formwork in use is large board combined from smaller plates, ensure they are firm and avoid impact to other structures when installation Must have working platform when installing formwork whose height not exceed 6m and when the installation of formwork height greater than m, delivered to experienced workers Ban placing or arranging the formwork boards or other components of formwork slip surface On the working platform and keep the load allowed and only placed the material on the platform in the position specified, must clean up excess material, waste material on the platform and gathered to the place specified NGUYEN XUAN TUNG_9907.56 202 Only dismantling formwork after concrete meets its enough strength, under guidance of technical staffs Dismantling formwork must follow the logical sequence, have measures to prevent formwork falling and fences, signage around the dismantlement area When dismantlement of formwork, always observe the status of structure, if there are any phenomenon of deformation, inform the technical staffs to have treatment measure timely In use of power in construction Electrical workers must be learned, tested and certified satisfactory electrical safety Electrical worker who in a construction area have to master power supply diagram of that area The site must have its electrical network diagrams, have general circuit breaker, breaker segments to be able to cut whole or each sector on site when needed The wires using on site must be insulated wires, are on the column at height of at least 2.5m toward construction plan and 5m toward where the vehicles pass The wires under 2.5 m from the construction plan must be rubbercoated wires All electrical equipment must be protected short circuit and overload protection devices (fuses, relays, aptomat, etc.) must be selected in accordance with the voltage and current of the device or group of devices that are protected When using the electric handheld devices, workers are not on ladder and stand on safety platform For heavy tools, workers have to make hanger or other ways ensuring safety Workers must take gloves, boots and shoes Only the power workers, who are directly assigned to newly repair, match or disconnect electrical appliances off the grid Only open the cover of equipment, any repairs when the power system is off Ban use of fixed lights to be handheld lights The lights at work are set at the positions such reasonably that not cause any troubles to the workers In fire resistance Comply the rules of fire resistance and take them to the construction site for people to study Place the firefighting equipment as sandbags, water tanks at the location having combustible materials Layout locations to take the water for fire resistance (well and mobile water tank), ready when the fire occurs Arrange workers who have been trained on fire rescue ready when a fire occurs Storages of materials, offices are equipped with fire protection systems 1.1 Safety in working with equipment, machines on site Vibrator NGUYEN XUAN TUNG_9907.56 203 Only workers who are assigned operate vibrators When operating, pay attention to the following: Check the power line from the power net to the vibrator Only switch the vibrator on after putting the breaker on, see the vibrator shake then bring it to work Not allow greater ¾ length of the needle vibrator to be deep in concrete When engine stop working, take the needle vibrator out of concrete Do not leave heavy thing on the flexible hose, the radius of curvature of the hose is not less than 40 cm and must not bend into segments The workers operating vibrator only dismantle its needle by specified equipment Not let the water be into the needle and hose When the needle gets jammed or the engine does not turn, must cut the needle form engine right now and inform to technical staff to have treatment 1.1 Environmental management Master plan sanitation Layout the location to wash motorbike and construction vehicles before they go out of the site Spray water on the roads around the site to prevent dust Arrange trucks to transport waste materials out of the site at time allowed of city traffic Arrange dedicated group to industrial hygiene and sanitation activities in and around the site Waste Wastewater, surface water is collected to makeshift trench connecting to the network of the region, not to the spill Waste at the site must be poured at the regulation location, every week, they are bring out of the site Arrange a private toilet area for the workers in the site and group of people regularly clean to avoid causing pollution to the surroundings Do not burn waste in construction site Noisy and dust resistance Due to site locates near residential areas, so pay attention to environmental problems, noise and dust resistance Time of gathering supplies and vehicles will be deployed appropriately Vehicles transporting materials to the site must have canvas covering, avoid sand, rock falling on the road The velocity of vehicles running on site is in limitation of km/h to avoid stirring dust In dry and sunny days, the contractor will spray water against a construction dust and wash for roads around construction sites and residential areas NGUYEN XUAN TUNG_9907.56 204 The construction equipment brought to the site must be tested and are the new devices restricting noise The car carrying the materials will be covered with canvas Once out of the site, all vehicles must be cleaned The waste is collected and dumped the right places Vehicles carrying
