Toilet details and mechanical pipe sleeves location for both indoor unit refrigeration pipes and sanitary fixtures ventilation. Block work except the shaft walls and water proofing activity should be done first before installation. Waiting pipes, drainage pipe,stub pipes and fittings from risers and underground pipes should be present before starting inside the toilet. Hollow vertical shaft or duct located nearby the toilet will not be cover to work easily inside the toilet especially connection to the risers. Assign the location of pipes in the wall or floor that is exactly as mention on the approved toilet details shop drawing. Use block cutter or simply portable grinder to cut a side of block continuously along the line that had been marked. By using sharp- pointed steel rod and other proper chipping tools, chip the block side to the thickness required to fixed the sanitary pipes. Standard fittings and materials must be used and all drainage pipe and fittings must be joined using the approved glue. Level of the slab should be identified by surveyor before proceeding installation. Also locate points as alternative reference point for pipe and pipe fittings installation. Sanitary fixtures outlet location should also be installed and identified. Connection of drainage pipes other than water closet drain i. Pipes and pipe fittings connection should be on the compacted fine sand and partly small of cement mortar as its support. Height distance between gully trap bottom and slab should be two 2 centimeter for all toilets. Absolute care should be imposed not to damage the water proofing upon installation. Install sleeves for pipes passing through the concrete or masonry walls. Put sealant in between the pipes and sleeves. Check the pipes securely fixed, joint and capped before leak testing. Leak test for the installed drainage pipe is to be carried-out with presence of inspector Engineer. After the approval of Inspector Engineer, cover the drainage pipe with cement plaster or sand to where it is applicable. Email address:.

Water pipe laying methodsAt the start of the project, in most projects I joined with, one of the activities shall be implemented or started first is excavation. You may copy this Method Statement and submit to the Engineer but please take a while to read your specification first as this may differ from it and revision will be needed. Services, wherever found shall be rerouted and protected to place will not affect site activities. Backfilling shall commence using similar excavated material. Care shall be taken to remove bolder, vegetations and any other deleterious materials. Thank you, sir, for your website of a method of statement. This website is very useful for me and then we get the water supply pipeline MOS. Hello Noel, am Stanley and I need your assistance, am doing a report on a proposed water pipeline for a certain area in my country.

Hume pipe laying method statementThis method statement is applicable for all drainage pipe works underground, above ground, horizontal and vertical drainage piping for any kind of the project as specified in project specification. It is responsibility of project manager and project plumbing engineer to ensure the availability of coordinated drawings and the required materials as per the project specifications. Perform the inspections on completion of reasonable part of work area wise or block wise as per consultant requirements. Generate an inspection request along with inspection checklist and after completing internal inspection call the consultant for witnessing the work inspection. Most of the cases site QC engineer and site engineer shall witness and accompany the inspections. Drainage pipe shall be tested as per the checklist. Within the building the plug piping section shall be tested by filling it with water at highest point, and test shall be carried out in floor intervals not higher than ten meters. Between manholes pipes shall be tested by plugging the inlet pipe to the upstream manhole and inlet pipe of the downstream manhole and filling the water to the top of the upstream manhole. No apparent loss of water should be noticed after four hours. Technical Submittal Requirements. Pipe and fittings shall be in conformance with the following unless specified otherwise by local authorities. Floor clean outs shall be provided as per the locations on shop drawings. Depending upon the connection it may be either 45 degree Roding eye or straight Roding eye. It should be uPVC material and should be supplied with cap, chrome plated copper plate and cover of overall size mm x mm. Each floor drain shall be of UPVC construction with mm water seal. Drain shall be fitted with 25mm access plug for cleaning purposes and shall be of the same material as the pipe connected to it. For temporary storage of the pipes in the site where racks are not provided the ground shall be level and free from loose stones. UPVC Pipes shall be protected from the direct rays from the sun by covering the pipes with polythene sheets or similar material. Drainage and vent piping shall be installed at the following minimum slopes if not specified anywhere else. Wherever required, pipe cutting shall be performed by a method which provides clean square cut of pipes and then chamfered as required. Pipes ends are chamfered to approximately 15 o for half the pipe wall thickness and debarred with a sharp edged tool. For pipe sizes 82 mm and above, jointing of pipes and fittings are carried out by Push-fit jointing method. The solvent and glue used in this method are Parabond P. Both surfaces to be joined shall be cleaned using a cleaning fluid. This removes all dirt and machine release agents and softens the surface ready for the chemical solvent weld. The pipe shall be inserted to the socket with a slight twisting action to full socket depth. Surplus cement shall be removed with a cloth. After pipe laying, Inspection and testing a further mm of approved bedding material shall be used for pipe surround, compacted with hand from all sides while tamping lightly over the crown. The bedding material shall span the entire width of the trench and shall be laid in not more than mm deep layers, each layer being compacted by hand. This is usually compacted infill with the original trench soil over the layer of pipe surround. Heavy mechanical rammers shall not be used until the fill has reached a sufficient height above the top of the pipe. Coordinated drawings and the required material is arranged by the site engineer as per the project specifications. If required get the safe work permit from HSE department.

Methodology start from hauling, stacking and handling of pipes, pipe laying, road works, etc until completion of the final testing and commissioning system and as built drawings. These materials will eventually be transferred to the pipe laying location for trench filling purpose by means of dump trucks. One saddle shall be at the center of the pipe length and the other two shall each be positioned at a distance one-fifth of the pipe length from each end of the pipe. The canvas sling will be position at approximately one-fifth of the pipe length from each end of pipe before lifting. On uneven ground the pipes will be supported on sand bags or earth bunds which give continuous support under not less then 40of the pipe circumference. The position of support shall be at a distance one-fifth of the pipe length from each end of the pipe. Upon confirmation of the proposed pipe route as per item 2. Excavation for pipe trench will be carried out by means of backhoe excavator or hydraulic excavator. Excavation is closely monitored to prevent over excavation. Once excavation is completed, the reduced level at the bottom of the trench is taken. This is required for computation of the excavated material and for compliance to the designed pipe level. At area with bad ground condition, appropriated shoring shall be provided to avoid the sides of excavated trench from collapse and ensure safe working condition within the pipe trench. At area with high water table or during raining season, dewatering pump shall be used to remove water within the pipe trench in order to provide a workable condition for the pipelaying, welding and other associated works within the pipe trench. Pipe laying will be carried out as soon as trenching is completed. Pipe will be laid to the lines and levels shown on the drawings or as otherwise directed by SO. The alignment for laying of pipes will strictly follow the alignment pegs given by the surveyor. Pipe shall be lifted by using reinforced canvas sling and slowly lower down to the trench until approximately 50mm above the formation level of the trench, in the lifted position. The alignment of the pipes is adjusted according to the requirement and the pipe mouth is brought closer to the other pipe mouth which has already been laid. Once both pipe mouths are aligned, the lifted pipe is push toward the laid pipe by means of excavator bucket to allow the pipe mouths to engage. Once this is done, the pipe is fully lower down and. Recess shall be provided during the trench excavation to facilitate the removal of sling belt. The welding machines to be used for the welding of the joints will be Miller amp. The gauge of electrodes will be 3. As for the mm pipe the gauge of the electrodes will be 4. The direction of the weld will be from bottom up hand upwards to the top of the pipe and the completed fillet weld will be full and convex in shape. Where the steel pipes are to be joined by welding it will be by means of an internal and an external circumferential electrical arc weld at each point. For mm pipe, only external circumferential welding is required base on specification. For mm pipe internal and external circumference welding are required. Before placing the pipes together the portion of the sockets and spigot to be welded will be cleaned to a bright metallic finish, the spigot end will then be placed in the socket and forced inside so that the spherical surfaces are in contact and that the gap between the pipes at the end of the spigot is nowhere greater than 1.
