These drawings shall show all openings for services, and up-stands or plinths for equipment and cast-in items.Method Of Strengthening R.C Slab After Deflection Using Over Lay Method
Bending schedules and reinforcement detail drawings shall be submitted for approval. The Contractor shall correct these schedules and resubmit as reasonably required to ensure a high standard of work. He shall program his work and submit schedules for approval allowing time for such verification, rectification and re-submission as necessary. Such approval shall not relieve the Contractor of his responsibility for the accuracy of such schedules.
No concreting shall be allowed to proceed until such time that the drawings and bending schedules for that particular section of works are approved. The Contractor shall submit full details of reinforcement that he proposes to use for making concrete. Approved materials shall not thereafter be altered or replaced by other materials without the consent of the consultant. All reinforcement shall comply with the appropriate British Standards, which include the following:.
All reinforcement for use in the Works shall be tested for compliance with the appropriate British Standard in a laboratory acceptable to the consultant and two copies of each test certificate shall be supplied to the consultant. The frequency of testing shall be as set out in the British Standard. In addition to the testing requirements described above, the Contractor shall carry out additional tests as instructed by the consultant. Where reinforcement couplers are specified or are permitted by the consultant they shall be used in accordance with the manufacturers recommendations.
The tensile strength and the fatigue performance of coupled sections of bar should comply with the relevant British Standard for the type of bar.
Tying Wire: tying wire shall be 1. The use of any other type requires the approval of the consultant. The ends of the wire shall be bent back away from the surface of the member to avoid rust staining. Spacers: the type of spacer requires the approval of the consultant. They shall be of durable material and shall be designed to avoid corrosion of reinforcement and spalling of concrete. Concrete spacer blocks shall be made from cement, sand and small size coarse aggregate.
The mix proportions shall match those of the surrounding concrete and the blocks shall be comparable to the surrounding concrete in strength, durability and appearance. Reinforcement shall be stored on Site either in racks or on a hard impermeable base so that it remains straight and free from contamination.

Any reinforcement that is likely to remain in storage for a long period shall be protected from the weather so as to avoid corrosion and pitting.Power Lines: Buildings shall not be constructed under or nearer than 10m to an overhead power supply.
If advice is required, or if power lines need to be diverted, it is the applicants responsibility to contact, in writing, the local ESB supervisor before construction commences and then to follow the ESB conditions. Site Preparation Excavate all topsoil to a minimum depth of mm. Any soft spots or areas of mud or dung on the surface will have to be excavated down to solid ground. A bit extra will need to be excavated where the channels are going to be located. The overall site should fall in the direction of the collection point s.
The fall in the site should reflect the fall on the finished surface and should lie somewhere in the range of 1 in 60 to 1 in Preparation for Foundations Place a layer of graded hard-core over the site and extend it at least mm beyond the proposed edges of the slab. Compact the hard-core with a vibrating roller to a finished depth of at least mm.
Hard-core placed in excavated soft spots or on made-up ground should be compacted in mm layers. Be extra thorough in compacting made-up ground. Blind the compacted hard-core with sand or dust and run the vibrating roller over it one last time to bed it in.
Lay a sheet of gauge polythene on the finished foundation. Concrete The area of the proposed silage slab shall be set out with timber shuttering supported in place to cast the concrete slab. A minimum 30N20 concrete mix shall be used. The required A steel mesh shall be placed in position, ensuring the required cover and lab length is maintained. Method Statement The channel sections around the perimeter of the slab shall be cast in accordance to the design, at a depth of mm and a width of mm.
Place and compact the concrete to a finished depth of mm, making sure the concrete is at least mm thick under the channels. The slab shall be compacted using a vibrating screed and poker vibrator, to ensure the removal of air trapped during the mixing process. To ensure the required fall of 1 in 60 from the edge of the slab to the start of it, a laser level shall be used.
Shallow tracks are useless. The joint should be cut deeper near the channels because the concrete is thickened there. Sealing Joints When the slab has cured properly the joints can be sealed. Prepare all the joints already cut by widening out near the surface with a concrete saw to mm wide and deep. Brush out all the joints thoroughly to remove all the dust and debris. Two broad types of sealant shall be used, either hot poured rubberised bitumen or gun applied polyurethane.
Care must be exercised in the use of concrete saws for cutting joints. Wear a suitable dusk mask giving P2 protection as well as ear, eye and foot protection. Hot rubberised bitumen is - C when ready for pouring. So, be sure to read the safety precautions on the product information. Method Statement Briefing Record Briefing delivered by: Position Date: We the undersigned have read and understood the attached method statement and will comply with the specified requirements and control measures.
If the work activity changes or deviates from the originally envisaged, we will seek further advice and request an amended method statement.After backfilling works the next is casting slab on grade groundmake sure that all the area beneath grade slab have been properly backfilled and compacted. Approval must be obtained from the Engineer for waterproofing and backfilling works prior to start slab on grade casting. Any method statement for fixing a concrete reservoir which is leaking due to honeycombing and segregation on some sections?
There is nothing wrong as long as the concrete has the same strength and make sure that your engineer agrees on that. I can gain the knowledge from your site which is really interesting. Thank you for this article because it is really informative about cement mortar mix it is really informative and gives best suggestion about it. Thanks a lot and have a great day. The plaster should be properly checked and should be within tolerance before the application of paint if it deviates more than the tolerance then it is really not acceptable.
Thank you Mr. Noel for the response. Today i received an NCR with description for the waviness in exterior walls textured paints. During my absence the external plastered walls were not inspected via IR and been painted. When i checked the wall surface, alignments and found to be within tolerances. Please guide me what will be the corrective measures should be taken inorder to close out the NCR.
Hope i will get answer for this. It should have been inspected and approved by the Engineer before the application of any coats of paint. This is my idea and perspective. Go first with the diplomatic way. If you checked the area and found the surface is within the tolerance, establish the evidence, gather the standard that shows the limit of deviation and then create a survey report that your site investigation is true.
There should be something proof and evidence and then if survey report is ready bring that to the Engineer along with the standard and show to them that the wall is within the tolerance.To browse Academia.
