14 2. TECHNOLOGICAL CARDS
15 2.1 TECHNOLOGICAL CARD OF FOUNDATION
16 2.1.1 GENERAL DESCRIPTION This technological card consists on the construction of deep foundation. The depth of piles is 5 m and the diameter is 40 cm. We are going to made reinforced concrete on-site piles. I choose this type of execution because is cheaper and we can control the whole process. 2.1.2 DESCRIPTION OF TECNOLOGY AND SEQUENCE OF WORKS The basics components of our foundation are: -Concrete HA-25 -Iron armors B500s CONSTRUCTION SEQUENCE (Figure 2.1): 1. Drilling (Figure 2.2). 2. Withdrawal and concreting. 3. Steel cage installation. 4. Headed pile. 5. Beam formwork. 6. Beam steel cage. 7. Beam concrete. Figure 2.1. Piles construction sequence
17 Works order: 1. Piles staking (Figure 2.3) Each pile has to be correctly positioned in plane or “line”. The drilling must also be plumbed. We will work from centre lines: the lines will be marked on the ground. We will have a main line of piles, and then any line parallel to this one at a knowning distance can be used. 2. Connecting piles with beams. Each pile must be headed to release iron armor and so to connect the beams to the piles. After removing excess piles’ concrete armors must be unfolded for proper placement in beams. 3. Leave Columns starts. When we connect piles’ steel cage with beams, we have to put also columns starting in their right position. Figure 2.2. Pile drilling
24 During placement of armor: - Armed reinforcement for vertical suspension for an introduction in the pile will be made by guide ropes attached to the free end. Never with bare hands. - Similarly, the personal protective equipment for hands, feet and head should be used. - Employees will be trained and informed in the proper handling of loads, as the diverse nature of the teams. When the dimensions of the load, or the weight of the same warrant, handling charges are held by personnel. - Also, all entries made in relation to the handling and placement of reinforcement for working are taken into account. - Special emphasis will be given in this chapter at the manipulation of metallic elements dominated by the length over width, such as tubes, steel bars, etc. So that they can contact overhead power lines. - It is advisable to collect waste and scrap reinforcement, storing them in an appropriate place for further transporting to landfill. During filling of piles: - All nominations made to the tasks of "foundation” will be considered, with special attention and caring to all those scrupulous use of PPE required. - Dug wells waiting to be concreted or armored shall be protected by guardrail with a safety distance from not less than 1.5 m. - When a concrete pile cannot be ready before the end of the day, it will be placed on the wellhead a metal grille to prevent accidental falling into the well at night or during periods of rest. - Whenever workers over 1.5m closer to the well, they should wear anti fall system anchored to a strong point. - At all times, the work area should be kept with proper housekeeping. - Operators responsible for managing and assisting the drilling equipment will be familiar with the following preventive rules: o Note that this machine is dangerous and can cause accidents. Be careful in handling. Adhere to these preventive measures and avoid the possibility of accidents. o Before starting work check the tires or chains. Warn of possible damage. A tire blowout in service could prove a serious accident. o Do not allow access to machine controls to unauthorized or untrained, because they can cause accidents or damage to other operators. o Check the condition of the bit. Consider that rupture can cause serious accidents. o Never operate this machine in situation of damage or semi breakdown. Have it repaired first and then resume work.
25 o After stoping the work and before putting the machine back in service, check that all pressure cuffs are right. A sleeve breakage can lead to accidents o The engineer is the only person authorized to manage the machine on each shift. You will be trained and informed. o When the machine is running, the driver will not be allowed to leave. o The maneuvering area rig will be cleared of equipment and drilling outsiders. o The driver and helpers on the coordination will be trained and informed of movements between them. Also, observe maneuvers loosening tool employing key supported on the mast. o Personal hands protective equipment should be used be. o Periodically, before starting the activity, a procedure must be established to monitor the status of the essential pieces that have to do with the safety of the drilling. o Extraction of land and the load on the truck will not run simultaneously on the same pile. The burden of land from the excavation will take place where piles have already been concreted, thus avoiding interference between man and machine. o All machines will have flashing light (flashing and rotating light) and audible (beeping horn and reverse). o Workers involved in the pilot, waste land excavation or any other task in work areas where there is a presence of vehicles or mobile machinery, should wear high visibility clothing. PROTECTION GROUP AND INDIVIDUAL. Mesh tape and markings. Certificated safety helmet. Protective gloves (leather, latex, neoprene, etc). Hearing protectors. Safety boots with toe protection and security staff. Safety boots with high rubber (with muddy terrain), with template and toe.

This is the North and west facades. This system is meeting all the criteria requirements of safety, noise and thermal. There are more modern solutions. The curtain wall makes the building looks sophisticated and modern. And it is a perfect combination with the other types of facades. 2.3.2 DESCRIPTION OF TECNOLOGY AND SEQUENCE OF WORKS Curtain wall is a highly developed type of façade over the last years in Lithuania because it protects the facade in reformation cases. There are many types of curtain wall. I have chosen this kind of curtain wall because it has not pronounced joints where water can enter and it damages the joints with the frozen and unfrozen periods. The brand of our curtain wall supplier will be “TECHNAL”. This curtain wall consists in an auxiliary frame where put glass modules (Figure 2.6). The dimensions of our curtain wall modules are principally two: 1000x2400x14 and 1100x2500x14 mm. Figure 2.7. Curtain wall details

Tolerances: • Maximum variation from plane or location shown on approved shop drawings: 3 mm per 3600 mm of length up to not more than 13 mm in any total length. • Maximum offset from true alignment between two identical members abutting end to end in line: 0.8 mm. • Sealant space between curtain wall mullion and adjacent construction: Maximum 19 mm and minimum 6 mm.
48 9. Door: 1) Install door in accordance with details indicated and approve shop drawing details. 2) Seal exterior metal joints among members of doors, frames, mullions and mullion covers in accordance. Remove excess of sealant. 3) After installing and glazing the doors, adjust the ventilators and hardware for operating smoothly and to be weather-tight when ventilators are closed and locked. Lubricate the hardware and moving parts. 4) Install to make weather-tight contact with frames when ventilators are closed and locked. Do not cause binding of sash or prevent ventilator closing and locking. 5) Provide for ventilating sections of all windows to insure a weather-tight seal meeting infiltration tests specified. Use easily replaceable factoryapplied weather-stripping of manufacturer’s stock type. 10. Joint Sealants: • Surfaces to be primed and sealed should be clean, dried when touching, free from frost, moisture, grease, oil, wax, lacquer, paint or other foreign matter. Enclose joints on three sides. Clean out grooves to proper depth. Joint dimensions should conform to approve detail drawings with a tolerance of plus 3 mm. do not apply compound unless ambient temperature is between 5 and 35 ºC degrees. Clean out loose particles and mortar just before sealing. Remove protective coatings or covering from surfaces in contact with sealants before applying sealants or tapes. Solvents used to remove coatings should be typed as those which leaves no residue on metals. • Match approved sample. Force compound into grooves with pressure enough to fill grooves solidly. Sealing compound shall be uniformly smooth and free of wrinkles and, unless indicated otherwise, shall be tooled and left sufficiently convex to result in a flush joint when drying. Do not trim edges of sealing material after joints are tooled. Mix only amounts of multi-component sealant which can be installed within four hours, but at no time shall this amount exceeds 19 liters. • Apply primer to masonry, concrete, wood and other surfaces as recommended by sealant manufacturer. Do not apply primer to surfaces which will be exposed after caulking is completed. • Tightly pack backing in bottom of joints which are over 13 mm in depth with specified backing material to depth indicated or specified. Roll backing material of hose or rod stock into joints to prevent lengthwise stretching. • Install bond preventive material at back or bottom of joint cavities in which no backstop material is required, covering full width and length of joint cavities.
49 • Remove compound smears from surfaces of materials adjacent to sealed joints as work progresses. Use masking tape on each side of joint where texture of adjacent material will be difficult to clean. Remove masking tape immediately after filling joint. Scrape off fresh compound from adjacent surfaces immediately and rub clean with approved solvent. Upon completion of caulking and sealing, remove remaining smears, stains and other soiling and leave work in cleaning neat condition. 11. Glass • Install in accordance with manufacturer’s recommendations as modified herein. • Before installing glass, inspect sash and frames to receive glass for defects such as dimensional variations, glass clearances, open joints or other conditions that will prevent satisfactory glass installation. Do not proceed with installation until defects have been corrected. • Clean sealing surfaces at perimeter of glass and sealing surfaces of rebates and stop beads before applying glazing compound, sealing compound, glazing tape or gaskets. Use only approved solvents and cleaning agents recommended by compound or gasket manufacturer. All sashes shall be designed for outside glazing. Provide continuous snap in glazing beads to suit glass as specified. • Insulate and tempered glass and glass of other types that exceed 100 united inches in size: Provide void space at head and jamb to allow glass to expand or move without exuding sealant. Perimeter frames and ventilator sections shall have glazing rebates providing an unobstructed glazing surfaces 19 mm in height. Glazing rebate surfaces must be sloped to shed water. • Provide adequate means to weep incidental water and condensation away from sealed edges of insulated glass units and out of wall system. Weeping of lock-strip gaskets should be in accordance with recommendation of glass manufacturer.

57 3.2 SELECTION OF TOWER CRANE In this part it is explained why we choose our tower crane LIEBBHERR 130 EC-B6. Tower crane are selecting by two ways: • According to technical parameters. • According to economical parameters In this task we are going to use the first way, we are going to select our crane according to technical parameters. This way is dividided into two steps: 1. Tower crane selection when the underground and over-ground works are fulfilling. 2. Tower crane selection when only the over-ground works are fulfilling. Calculation of technological parameter of tower crane. First of all we have to know the following parameters: 1. Building dimensions and location (underground and over-ground parts). 2. Weights, dimensions and location of installing constructions. 3. Work conditions (building site particularities, soil characteristics and underground structures peculiarities). We must check if crane technical characteristics match the inequalities: Qk>Qr Hk>Hr Lk>Lr Qkascension power of selected crane ,t. Qrrequired ascension power, t. Hkreach of selected crane boom, m. Hrrequired reach of crane boom, m. Lk-lifting height of selected crane hook, m. Lrrequired lifting height of hook, m. The technological parameters of crane are calculated according to the building characteristics. The required crane is selected according to crane technical characteristics table.
58 Tower crane selection when the underground and over-ground works are fulfilling. First of all we are going to determinate height requires of hook lifting: Hr= Building height + 3m= 7.2+3=10.2m Then the ascension power of crane: Qr= P + Pstr = 2.5+0.15= 2.65t P-weight of heaviest lifting construction, t (in our case concrete for columns) Pstrweight of hitching equipment, t When the values of Lr, Hr and Qr are calculated, the crane could be selected. Whereas for determining the reach of crane boom Lr, will be needed to know the under crane width of supports and dimensions of platform turn. These values are found in crane diagrams. The reach of crane boom Lr is calculated according to our needs. I decide to put the crane in the floor of the building, in the south-west corner, because in this corner we haven’t facade, so the crane doesn’t disturb us in the constructive process and it can minimize the tower arm length. Lr = 35 m. When we know the values of Lr, Hr and Qr, the crane could be selected using the diagrams of the tower crane. The diagrams show that the crane we can use is LIEBBHERR 130 EC-B6. Qk>Qr 3t>2.65t Hk>Hr 17.2m>10.2m. Lk>Lr 35m>32.5m As we can see, the crane we have selected is capable of performing the required works.
63 3.3 SETTING OF DANGEROUS ZONE During the installment works in some parts of the construction site, bars, workplaces and crossings the dangerous areas are appearing. During the construction such areas are known as dangerous zones. At the beginning of construction works and during construction dangerous zones, in which constantly arise or may arise risk factors should be determined. The dangerous zones are dividing into two groups: 1. Dangerous zones in which dangerous and/or hazardous factors constantly affect the processes. 2. Dangerous zones in which dangerous factors could appear. - Dangerous zones in which dangerous and/or hazardous factors constantly affect the processes, are: • Near the electrical equipment with non-insulated parts electric current • Fenceless zones at a height when height difference is 1.3 m higher • Place where hazardous wastes and/or the concentration of harmful substances in workplace air may exceed the limit values. (Table 3.1) Limiting the dangerous zones from the fenceless un-insulated parts of the electrical equipment Voltage, kW Distances, limiting the dangerous zones from the fenceless un-insulated parts of the electrical equipment or from the vertical plane, which is the nearest power line wire, with a projection on the land, m <1 1.5 1-20 2.0 35-110 4.0 150-220 5.0 330 6.0 500-750 9.0 800(current) 9.0 The limits of dangerous zones where the risk factors of harmful substances exceeding appears should be determined by measurement. 2. Dangerous zones in which dangerous factors could appear are: • Near buildings under construction and assembling/dismantling buildings structures or equipment. • Places over which the structures or equipment installation/dismantling works are executing. • Places over which loads are lifting and transported by cranes. • Places where the machinery, their parts or work equipment are moving.
64 The determination of crane dangerous zones The limits of dangerous zones where there is a transfer of elements performed by crane are determined by calculations, the sum of horizontal projection of lifted element, the maximum length of biggest elements and its possible fall distance. Due to the conditions surrounding our lot we have to consider our danger zone should not override existing buildings. Then, let put some limitations on the movement of loads with the crane: - Raise the load vertically to a reasonable height, and then carry the load to the centre turning radius to reduce the area of danger zone. - The projection of the arm of crane will not be performed on existing buildings. The next risk will be considered: -Presence of obstacles. -Areas of way. -Jobs in proximity to high voltage power lines. The prevention measures are established on the basis of the following legal text: -Royal Decree 836/2003 of 27 June, approving a new Technical Instruction “MIEAEM2” Regulations Lifting and handling equipment, referring to tower cranes for construction or other applications. -Royal Decree 1215/1997 of 18 July, laying down minimum safety and health for use by workers in teams.
65 Presence of obstacles In paragraph 7.3 of the UNE 58-101-92, states: “The vertical clearance between the pen and the last area of movement of personnel shall be minimum 3 meters. If the load or empty hook passes within 3 meters of the area (Figure 3.1), will be necessary placed on it enough to prevent the indicators of his approach.” This means that when the crane weathervane turn must respect the distances. And the area, which inevitably we must consider the burden. We are not inclined to use signaling and also taking into account the flexibility of these structures, walkways in paragraph 4.1 of the UNE 58-101-92 states: ”The minimum clearance for the passage of personnel, among the most prominent parts of the crane and any obstacle is 0.60 meters wide and 2.50 meters high. In case of failure application of this condition will prohibit the access of staff to this area dangerous”. We have considered a minimum distance between the tip of the arrow and the nearest obstacle of 2 meters(Figure 3.1). (Figure 3.1). Diagram of tower crane safety distances.
66 3.4 TEMPORARY ROADS TO THE BUILDING PLACE Temporary roads are built to bring construction materials. Temporary roads are built combining existing roads to reach warehouses, work places, machines, etc. outside the building place. There are two different ways of temporary roads. The wide of the road has to be at least 6 meters, and the smallest distance from the road to the storage place is 1 meter. These roads are built to ensure easy driving to the building place and fast work. 3.5 TEMPORARY STORAGE BUILDINGS AND SITES The construction site will contain two storage buildings model C20-P on the east side of the field (6x2.44x2.60 m) to store all tools; also we will need one on covered site (according the length of truss) on west side of the construction plot. 3.6 TEMPORARY BUILDINGS FOR WORKERS AND MANAGING All the staff will have their own temporary buildings to satisfy all their needs. We calculate all the necessary temporary buildings knowing the workers volume. According on “Royal Decree 486/1997, of 14 of April laying down general provisions minimum safety and health in the workplace” approaching the changing surface of 2 m 2 per worker. The maximum number of workers that we will have working at same time will be 33. So we calculate 66 m 2 of surface for temporary changing building. 1 sink/ 10 workers 1 shower/ 10 workers 1 toilet / 10 workers 1mirror / 10 workers S= 33x2 m 2 = 66 m 2 . Chosen Buildings: - 1 Toilet Model M 65 (6.00x2.44m) = 14.64 m 2 . - 1 Model M 6C (6.00x2.44m) = 14.64 m 2 . - 1 Model M 6 (6.00x2.44m) = 43.92 m 2 . The workers will use a temporary buildings Model M 6 as place for rest, eat…; and the Model M 65 as toilet and shower. The managing staff will have one temporary building Model M 6C, where will be situated the office.
67 3.7 TEMPORARY ELECTRICITY SUPPLY A temporary supply will be needed in order to make mostly all the works. A general electricity counter will be needed in the building fence connected to the electrical rush supply connected to the general electrical city system placed close the road, will be made an individual 4x16mm 2 derivation. 3.8 CONSRUCTION SITE LIGHTNING To calculate the number of luminaries necessary for the correct work illumination (Formula 3.1): N= ா௫ ∅ ௫ி ೆೣಷಾ (Formula 3.1) Where: N: Luminaries number are required E: Average luminance in lux A: Local area m 2 ∅ n : flow lamp rate in lumens F U : Factor of use F M : Maintenance factor The surface of the work area is 4300 m 2 , to be illuminated with an average illumination of 15 lux, with 1x150 W metal halide lamps, which produce a luminous flux of 13000 lumens per lamp. Will be used a normal maintenance factor 0.95. Data from the lighting area are: Length: 91.60 m Width: 33.85 m Height: 4.50 m Index K= ௫ ሺାሻ = ସଷ ସ.ହሺଽଵ.ାଷଷ.଼ହሻ = 7.61 With this index, and media with floor colors and ceiling, and clearing to the walls, is a factor in initial use in direct lighting luminarie 1.
68 This the lamps number required will be: N= ா௫ ∅ ௫ி ೆೣಷಾ = ଵହ௫ସଷ ଵଷ௫ଵ௫.ଽହ ≈ 6 By calculation we have obtained that we need a minimum of 6 lamps. 3.9 TEMPORARY WATER SUPPLY We will need a temporary water supply (Figure 3.2). A general accountant will be installed in the building fence connected to the city water supply rush placed close to the road. The temporary water supply line will require an accountant, stopcock general, pipe tube 32 mm, wash step and tap. (Figure 3.2).Temporary water supply.
69 3.10 TEMPORARY SEWERAGE The sewer construction will consist on removing water from rain and the elimination of waste water as a shower, basins and toilets. Drainage is connected to the network of urban wastewater. The drainage plan consist on connecting our network to existing networks of the city. The sewerage system will have a diameter of 200 mm. 3.11 FENCE OF CONSTRUCTION FIELD The construction fence will protect the parcel’s perimeter. The maximum width of the strip of public or private space to be occupied by work of fenced will be of 2 meters. The minimum step width should cover the separation or boundary between pedestrian and traffic. Formal conditions: - The fence will be forced to have a minimum height of 2 meters measured at any point on the outer fence face. - The crown height is uniformed and horizontal projection admitting only to suit the terrain slopes, subject to compliance with the minimum height indicated in the previous section. - Is expressly forbidden ridges and sharp objects, which can be incorporated into the fence, both temporarily and permanently. - The outer fence face shall not allow the visualization hollow interior or protrusions or holes that allow the stencil. The projections requiring good performance of the fencing construction will be made, wherever possible, by the inner face thereof. - It Is not allowed to over the space of public or private road bounded by the fencing work. It will be mandatory the placement of lights signaling pathway hedges occupying public or private. - We will need 232.57 meters for the entire perimeter. - The fence will be opaque, perfect for construction by the rapid assembly and disassemble. 3.12 TEMPORARY COMUNICATIONS Temporary communications will consist on cell phones and USB modem internet for laptops (three of them) in managing temporary building.
