'RC design\r'

'This accounting entry presents the method command and equivalent temporary utilization design for the complex body part of low-rise building (LRB). groundwork radical forget be chosen for the tooshie of structure. Design calculation and drawing for the structure, Including beams, columns, foundations, w everys, floor slabs provide be shown in the following categories. Furthermore, formwork will be adopted for the construction of structure and timber formwork will be the premier(prenominal) priority. .

The overall sequence of construction is generally dual-lane into following stages: Stage 1 (Excavation) 1. Carry out underground utilities detection 2. Excavate down to +4. 3mPD to 3. 1 mPD 3.Perform compaction Stage 2 (Foundation) A. Steel readying 1 . According to the drawings, prepare the trade names with appropriate length, crimp angle and diameter. 2. According to the drawings, placing the steels in corresponding position and spacing. 3. Pack the steel together, extra steel crouch inwards to prevent exposing outside the concrete. 4. Leaving roughly space for trimming bar B. Formwork 5. vouch the functional scope is clean and clear, and with appropriate ligament. 6. According to the drawing, assemble the timber on the surrounding and fix tightl y with nails and screw.Make sure there arent any gaps. 7. Brush an crude oil layer on the inner face of timber. C. Concreting 8. Ensure the strength of concrete is with required slump 9. Placing fulgent layer on the bottom of foundation. 10. Placing concrete as on the body politic. For separated injection, each layer should not exceed 450mm tall 11. Perform compaction with trembling tube. commemorate that ibration tube should not place succeeding(prenominal) to the timber and not to control the flow of concrete. 12. shed the top of concrete when appropriate level of concrete is placed. 13.Timber flush toilet be take after 16 hours and check whether there are cracks. 14.

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 about(prenominal) space for trimming bar 9. Placing concrete every bit 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 contiguous 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 withdraw after 16 hours and check whether there are cracks 13. Perform curing by cover the concrete with plastic sheet 8.

Construction of flash and third floor, same as construction of first floor temporarily. 10. Environmental Protection Measures Any spoil, rubble or silt from construction works area shall be deposited at esignated area within the site as specified in the waste focus plan.Such spoil, debris and silt shall be immediately removed and avoid falling into adjacent areas. Drip/ pin trays will be provided to all machines and the fuel computer memory tanks or drums. All power equipment shall have appropriate silencers. Construction plant will be kept in unafraid condition and will be properly maintained. Construction activities will be limited to daytime hours as far as possible. All construction works will be carried out limited to the approved working hours subject to the blessing of Environmental Protection segment (EPD) and Drainage run department (DSD).Frequently cleaning and body of watering the site area to minimize dust emissions. Burning debris or any material shall be prohibited on site at all times. Air and incumbrance pollution will be monitored on a regular basis in accordance with the Air Quality & flutter Management Plan. Noise permit shall be obtained from the Environmental Protection Department (EPD) prior to any construction work beyond normal working hours. Chemical waste poke license shall be obtained before any chemical substance waste disposed offsite. Surface runoff water arising from the site shall be collected by temporary drainage system.Such temporary drainage system imperturbable of sand bags and temporary channels 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. twine washing bays will be located at the entrances in set to keep a good housekeeping condition inside the site. 11 . h appening 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 heavily E&M equipment will be handled by the addition cranes on site. Material availability such as concrete, wages and formwork can be delivered on site shortly. Normally, 1 †2 days advance ordering period is required for the processing from ordering to on site delivery. In view of the current market, no shortage of same material supply is found. Disposal of the material system has already been set-up. All disposal records and submissions are in order in compliance with statutory requirements.\r\n'
