RC design
This submission presents the method statement and corresponding temporary cypher design for the construction of low-rise building (LRB). Footing foundation leave be chosen for the foundation of grammatical construction. Design calculation and drawing for the structure, Including beams, columns, foundations, environs, news report slabs ordain be shown in the following categories. Furthermore, formwork entrust be pick out for the construction of structure and baseball bat formwork will be the starting signal priority. . outline of RC Structure Dimension Element Member Size (mm) Type of formwork fanny Timber Slab 250 Beam 500 x 500 x 5000 Ofs one hundred fifty Column 500 x 500 All cover work sh altogether told conform to the General Specification as following Elements Grade wall(a) Blinding mould strengthener 35 260, 460 MPa 4. Competent Persons for eddys of the Low-rise construction (LRB) Structure Construction Manager Engineer He shall supervise all technical item s of construction whole kit of MPS 2 structure, but not limited to the following items 1 .To handle the difficulties during the construction. 2. All required tests line of battle and Submission to the Engineer 3. Prep ar the erticality monitoring records and submit to the Engineer 4. To get, perform and implement the documented system in compliance with statutory requirements. Construction Supervisor/ General Foremen He shall be full time on rate to supervise the following works. 1 . To supervise and arrange all the MPS 2 construction works. 2. To arrange and monitor all relevant tests to structural works. . To arrange all setting-out works for MPS 2 structure constructions. 4. To follow the approved method statement for construction Safety policeman He/ She shall be full time on land site. His/ Her major duties are carrying ut ceaseless checking on the implementation of the safety measures adopted with telephone extension to regulations. Safety Supervisor He shall be fu ll time on site. His major duties are assisting the Safety Officer to carry out regular safety checking and supervise the construction works for the safety aspects.environmental Officer He shall be full time on site to oversee all the environmental and sanitary issue during the construction. Surveyor He shall be full time on site. His major duties are carrying out the site setting-out and monitoring works including verticality checking, settlement of ground measurement until completion. Certified Workers They must be at least 18 years old and be a holder of a certificate issued by a person whom the interposition Plants. The contractor shall ensure the certified workers being physically and mentally capable for construction works. 5.Plants Plants and equipments Lifting appliances line of credit Compressors Generator Water pumps Portable pneumatic breaker Welding Machine Hand tools Carpenter Rebar fixer Concretor General task According to the site condition and requirement of completion of each phase, the site operation will be arranged in stages corresponding to contrastive site logistic plans at ifferent time frame of construction. The overall sequence of construction is generally divided into following stages Stage 1 (Excavation) 1. discharge out underground utilities detection 2. Excavate down to +4. 3mPD to 3. 1 mPD 3.Perform coalescence Stage 2 (Foundation) A. Steel preparation 1 . According to the drawings, prepare the steels with seize length, bending angle and diameter. 2. According to the drawings, placing the steels in corresponding location and spacing. 3. Pack the steel together, unembellished steel bend inwards to interrupt exposing outside the cover. 4. Leaving around space for trimming bar B. Formwork 5. suss out the working area is clean and clear, and with appropriate ligament. 6. According to the drawing, install the lumber on the surrounding and fix tightly with nails and screw.Make sure thither arent any gaps. 7. Brush a n oil layer on the inner face of timber. C. Concreting 8. procure the strength of concrete is with required slump 9. Placing blinding layer on the bottom of foundation. 10. Placing concrete evenly on the area. For disjointed injection, each layer should not exceed 450mm tall 11. Perform compaction with shudder tube. line of descent that ibration tube should not place next to the timber and not to assure the flow of concrete. 12. Flatten the top of concrete when appropriate level of concrete is placed. 13.Timber can be withdraw after 16 hours and check whether there are cracks. 14. Perform circle by cover the concrete with pliant sheet and al-Qaida Slab 1 . According to the drawings, prepare the steel with appropriate length, diameter, bending angle, shape. 2. According to the drawings, placing the steels in corresponding location, and spacing. 3. Pack the steel together, extra steel bend inwards to prevent exposing outside the concrete. . Leaving some space for trimming bar 9. Placing concrete evenly on the area. For separated injection, each layer should not exceed 450mm tall 10.Perform compaction with vibration tube. Note that vibration tube should not place next to the timber and not to control the flow of concrete. 11 . Flatten the top of concrete when appropriate level of concrete is placed. 12. Timber can be removed after 16 hours and check whether there are cracks 13. Perform lot by cover the concrete with plastic sheet 8. Construction influence 1 Excavation and Compaction 2 Construct foundation 2. 1 Reinforcement bar fixing . 2 Formwork elevation 2. 3 Concreting and curing 3 Construction of first floor 3. 1 Column 3. 1. Reinforcement bar fixing 3. 1. 2 Formwork elevation 3. 2 wall 3. 2. 1 Reinforcement bar fixing 3. 2. 2 Formwork elevation 3. 3 Bearn 3. 3. 1 Reinforcement bar fixing 3. 3. 2 Formwork elevation 3. 4 Floor Slab 3. 4. 1 Reinforcement bar fixing 3. 4. 2 Formwork elevation 3. 5 Concreting 4. Construction of second and third floor, same as construction of first floor temporarily. 10. Environmental Protection Measures Any spoil, dust or choke off from construction works area shall be deposited at esignated area in spite of appearance the site as specified in the waste management plan.Such spoil, debris and silt shall be immediately removed and avoid falling into contiguous areas. Drip/ spill trays will be provided to all machines and the fuel transshipment center tanks or drums. All power equipment shall have proper silencers. Construction kit and boodle will be kept in good condition and will be properly maintained. Construction activities will be limited to mean solar day hours as far as possible. All construction works will be carried out limited to the approved working hours subject to the compliment of Environmental Protection Department (EPD) and Drainage Services department (DSD).Frequently cleanup spot and watering the site area to minimize dust emissions. Burning debris or any material shall be prohibited on site at all times. Air and noise pollution will be monitored on a regular basis in accordance with the Air Quality & Noise Management Plan. Noise permit shall be obtained from the Environmental Protection Department (EPD) prior to any construction work beyond normal working hours. Chemical waste discharge license shall be obtained before any chemical waste disposed offsite. Surface overspill water arising from the site shall be collected by temporary drainpipe system.Such temporary drainage system composed of sand bags and temporary take along the site boundary. The collected surface runoff shall be de-silted at the sedimentation tanks before discharged to public drainage system. The temporary drainage management plan has been submitted separately. Wheel washing bays will be set(p) at the entrances in enunciate to keep a good keep condition inside the site. 11 . Contingency Plan Lifting appliances such as mobile cranes can be deployed on site in order to speed p. Catch up the progress of works.In addition, some major hard E&M equipment will be handled by the addition cranes on site. Material availability such as concrete, reinforcement and formwork can be delivered on site shortly. Normally, 1 2 days advance ordering catamenia is required for the processing from ordering to on site delivery. In assure of the current market, no shortage of aforesaid material supply is found. brass of the material system has already been set-up. All disposal records and submissions are in order in compliance with statutory requirements.
