Besides, there is air conditioning system. The pipe system is laid in the vertical and horizontal technical box, distributes evenly to the places of consumption.3.2 Lighting systemNatural light is fully utilized. The window systems in all facades are glazed. In addition, artificial light is also arranged so that it can cover all points that need lighting. 3.3 Traffic system The vertical transportation system consists of two liftsFurthermore, there are also two escape staircases at two building’s sides. The horizontal transportation is arranged suitable for moving requirement. That is based on the function of each area. External trafic solution: Private path around the building.3.4 Power supplying system Electric system: 3 phase electric from local electric cabinet comes to electrical engineering room. After that, electric is distributed to all rooms. Moreover, there is a generator to supply electric automatically for elevator and hallway when electric system get incidents.Using power was delivered from power system of the city, building has transformer, beside there is a stand by generator in base floor. Lighting system ensures illumination from 20 – 40 lux. Special is middle corridor that is needed lighting all night and day for ensuring transportation. All offices have underground power line and electric tablet. Other rooms have more lighting requirement that was installed high quality lighting equipment. 3.5 Water supplying system and drainage system 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.Drainage system, Ventilation system: Drainage system consist of two parts. The first part is dirt drains and another part bring dung to septic tanks. Ventilation system has snorkel higher than elevation of roof by 700 mm.3.6 Fire fighting system Fire alarm system : Fire alarm detection devices are arranged in each room at every floor, public place of each floor. Fire alarm network is mounted alarm clocks and lamps. The management department controls fire as soon as receive the fire signal.Firefighting system: This system is designed based on the fire prevention requirements and other relevant standards (including fire preventing component, escape exits, firefighting water). CO2 cylinders are set at the intersections in all stories.3.7 Information technology system.Structured Cabling System for telephone and internetTV (cable, satellite)Public security system, CCTVAccess control system by magnetic card, fingerprint (Access Control)Public Address SystemAutomation System for Apartments (Home Automation) PART 2STRUCTURE( 45% ) INSTRUCTOR : VU ANH TUAN STUDENT : NGUYEN HONG TRUONGCLASS : 57XE2STUDENT ID : 3833.57TASK :Selecting structural solutions Determine loads applying on the building CHAPTER I : SOLUTION IN STRUCTURE1. SELECTING STRUCTURAL SOLUTIONS1.1 Main structure Frame systemThis system is created from vertical bars (columns) connecting with horizontal bars (beams), called “node”. The plane frames are connected to each other in order to make a space frame. In order to increase the horizontal rigidity of frame, braces are added at some span along its height. This component works as a horizontal rigid wall.Advantages: Construction method is simple. This system has large space, flexible plan, and meets all using requirement of the building.Disadvantages: The horizontal rigidity of frame is small, so that horizontal load bearing capacity is low. The beams have big depth that affects to using function and increases the building’s height. Frame system is suitable for low rise building (less than 20 stories for reinforced concrete frame)Bearing wall system In this kind of structure, plane walls are the main bearing elements. In building where walls are installed in one direction, the stability of building in perpendicular direction is ensured by rigid walls. For high rise building, horizontal load is big so that the wall plates are designed to bear all horizontal and vertical loads. The horizontal load is transferred to wall plates through slab system that is absolutely considered as rigidity in its plane. Therefore, rigid walls work as continuous beams with high depth of section. Advantages: By using wall system we can remove the concentration of stress at beamcolumn connection. This system will have torsional rigidity if the walls are connected to each other. It also has great horizontal load bearing capacity, so that this system is suitable for building requiring partition space (house, hotel…).Disadvantages: Using space is limited by walls. The walls has high weight, high rigidity so that the effect of earthquake is big. The buildings will be wall system is commonly less than 20 stories.Framecore system Rigid walls are connected to each other to form a closed (or open) space frame, call “core”. Core has blank box in shape and receives loads then transfers them to earth. Most of the inner space is used for vertical transportation equipment (lift, staircase), technical pipe system (water pipe, electrical pipe). The main advantage of this system is its high bearing capacity of horizontal load and high torsional rigidity. The core works as a big continuous beam fixed to foundation1.2 Slab structure system For building, slab system has big effect on the working of structure. Select structure method is very important. Therefore, we must a proper analysis to choose the method which is suitable for building.Slabrib system Consist of beam system and slabAdvantages: Simple calculation. Used popular in Vietnam, because of structure technology plentiful.Disadvantages: The height of beam and the deflection of slab are very big. Therefore the height of building must be big. That is not saving for cost of materials. not saving space.Mass slab system with four ribs Consist of vertical beam system which divides slabs to smaller slabs with 4 ribs.Advantages: Decreasing the number of column inside the building. Therefore, that saves using space and makes the architecture of building more beautifully. The structure is suitable for the building which is required the high level of aesthetic and big using space .Disadvantages: Not saving, complicated construction. When the area of floor too large, we need to arrange more main beam. Thus, the disadvantage is big height of beam. Slab without beam:Advantages: The height of structure elements is small. Thus, that decreasing the height of building. Saving using space. Easy to divide space. Easy to arrange water and electric technology system. Suitable for building which has medium. Construction of the method is faster than beamslab method, because of not be taking time by reinforcing formwork, reinforcing steel of beam. Because, the height of beams decreases, vertical transportation decreases and cost of construction decreases. Horizontal load decreases, because of the height of building decreases.Disadvantages: The column is not connective. Thus stiffness of frame is smaller than “slab without beam” method. Therefore, horizontal load is loaded by rigid wall. The thickness of slab is big to ensuring the bending resistance ability and antipuncture ability. Thus, the weight of slab is big.1.3 ConclusionBecause, construction is high building which has the big distance between columns. Moreover, to ensure the aesthetic of building, I choose main structure method of building: Pile structure for foundation. Mass slab structure with four ribs. Main structure of building is framecore frame. They create a grid system which support for slab. Rigid walls and columns is buckling to foundation system.2.

NGUYEN HONG TRUONG – Class: 57XE2 Page 192 PROJECT: ROYAL HOTEL FINAL PROJECT CONSTRUCTION SCHEDULE Major principles organization: as below are required for successful construction Optimal Economic effectiveness: the selected construction solutions must meet the following requirements: - Such solutions are able to shorten the construction time - To intensify labor productivity and save labor cost - To save construction cost - To improve the construction quality - To meet some general and safety, environment sanitation, etc particular requirements like: labor health & Use of mechanization methods, advanced technical equipment and tools: This approach is following the development trend of construction technologies wherein more and more machines are applied in construction to save manpower The production organization method can be changed from Production on site to production in industrial plants (where details needed for the construction on site are prepared and produced Construction sites are places where details are fabricated to make final products) Optimal Organization of work: This approach requires construction period to be divided into separate manipulations, aiming to appropriate allocation of manpower, intensive professionalization for enhancing working productivity and workers skill Working methods are required to be changed, in which excessive or unnecessary manipulations would be eliminated (optimal working) Effective time spending, restricting idle time, etc Standardization and modularization for construction: Standardization is the establishment of technical standards and codes for better application in actual condition This would help construction to be economically and technically effective Standardization sets out particular orders and technical requirements which are obligatory for the construction period Modularization is the establishment of regulars and specifications for products like dimension, nature… in the way that such regulars and specifications would be commonly applied and could be convertible or replaceable in the structure of the project CONSTRUCTION OGANIZATION METHOD Student: NGUYEN HONG TRUONG – Class: 57XE2 Page 193 PROJECT: ROYAL HOTEL FINAL PROJECT Currently, there are 03 major methods for construction organization, respectively: - Sequence method - Simultaneous method - “Line of balance” method Each method has its own advantages and disadvantages, would be partially or fully applied depended on particular conditions, with a purpose of the most effectiveness of production and construction For the super structure of this building, the “Line of balance” method is the most suitable method This is the logical combination of Sequence method and Simultaneous method, which narrows the disadvantages and enhance the advantages of both above methods With this method, the construction period of one product is divided into smaller phases, construction time for each phase is all similar The coordination is smoothly deployed in term of time and space based on the following principles: - Smaller phases of same products would be implemented by sequence, from one product to another product - Smaller phases of different products would be implemented simultaneously on different products In general, the construction method based on “line of balance” on is the most advanced method thanks to appropriate allocation of manpower, specialization of manipulations and cooperation in production Its outstanding features are high level of specialization of particular locations and positions on construction site; narrowing the list of products for manufacturing; balancing the production capacity; and the continuous, smooth and simultaneous performance of smaller phases This method at last results in shorter time of production, more products, lower cost and lower price, constant requirements of manpower and materials This method in construction has 02 main features: - As the construction product is associated with land and is big in size, it is required to also move the workers with their accompanied tools/equipment from one to the other locations and spaces This makes the “Line of balance” method different with the “industrial line” where the workers and their tools stand still while products keep on moving Consequently, the organization of “production line” method in construction is much harder - As the construction product is unique and diversified, most of production line is for short-term use Its stability is little or very limited This requires re-organization for construction of new project after a short period of time Student: NGUYEN HONG TRUONG – Class: 57XE2 Page 194 PROJECT: ROYAL HOTEL FINAL PROJECT Table III.12 Duration of typical

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
