Pin On Cad Architecture

The length of the reinforcement cage must be in accordance with the pile toe level and cut off level provided in the drawing.

. Tolerances Requirements In accordance with EN 15362010 Execution of Special Geotechnical Works Bored Piles Pile Position and Verticality. The chipping activity shall be in compliance with the cut-off levels as per approved shop drawings. The concrete will be brought up to the working level at least 10m above the cut-off level to ensure good quality and contamination free concrete at pile cut-off level.

Pile cut off levels shall be shown on the shop drawings to be submitted by the Contractor for approval of the Engineer-in. Pile Cut-off level is the actual level at which the piles below pier are made to be of the same level. Types of pile foundations are commonly known as floating pile foundations.

For each additional 03 m increase in cut-off level below the working level additional coverage of minimum 50 mm shall be allowed. Pile must be free from cracks and unsound concrete. The concrete above cut-off level will be chipped by the Main Contractor.

Pile chipping breaking will be done with air compressor and pneumatic concrete breaker from top of existing pile until cut off level. For piles with cut-off levels which are substantially lower than the working platform level concrete shall be casted up to 20 m above cut off level of pile. Pile Cut-off level belongs to the actual level at which the piles underneath the pier are constructed so as to retain the same level.

The contractor workers shall trim all permanent excavation to the convenience slopes and shall leave the surfaces smooth and even. Pile Cap Design Example 1. The cut off level of the pile would be as per the relevant drawings.

Ensure that the piles are set out as per the drawing co-ordinates or from gridlines in either case. The concrete of pile is cut-off at the specified level given in the specifications or drawings usually around 75 mm while the steel is kept projected in-to the pile cap to make an effective bond. It shall be removed and the pile will be repaired.

Where cut-off level is less than 25 m below the ground level concrete shall be cast to a minimum of 600 mm above cut-off level. The engineer will need to be in attendance as piling progresses to set out additional. The out-of-plumb or verticality tolerance is 175 and this too must be checked.

Concrete will be removed up to cut off level. Pile heads shall be cut to the levels shown on the Drawings and the cut shall be level smooth and horizontal. Excavation for Pile Cap Location Using JCB excavate the pile cap as per level and guidelines shown in the approved for construction drawings and approved shop drawings.

Increase pile cap depth to allow for sufficient anchorage of the piles into the pile cap. Due care shall be taken to protect the edges and reinforcement. The normal tolerance for piles at pile cut-off level ie below the piling platform level is -75mm in plan.

76 Casting Concrete must be According to Specifications. Determine number of piles for foundation A series of apartments is being constructed on clay ground. Where pile cut-off levels are higher than the commencing surface it may be necessary to extend the piles.

A service crane will lower the pre-fabricated reinforcement cage into the pile shaft. The concrete of pile is cut-off at the specified level given in the specifications or drawings usually around 75 mm while the steel is kept projected in-to the pile cap to make an effective bond. 146 Combination of friction piles and cohesion piles An extension of the end bearing pile when the bearing stratum is not hard such as a firm clay.

No extra payment shall be made for this work. However in-situ soil shall be used for back-filling borehole for remaining borehole depth from platform level until top of concrete level 20 m above COL. Iowa Department of Transportation.

Piles cut-off levels are 75mm. If concrete under the cut off level is unsound. Pile Foundation Pile Cut-off level is the actual level at which the piles below pier are made to be of the same level.

The spiral must be according to the approved drawingsdesign. The concrete of pile is cut-off at the certain level provided in the specifications or drawings normally around 75 mm whereas the steel is arranged in-to the pile cap to maintain a strong connection among pile cap and piles. Plan position for bored piles at commencing surface will be within 005 x d1 with 10 m d1 15 m 60 mm in any.

Weld main bars with links at the top of the reinforcement cage and use U-Clips to hold the main bars and main links together for lifting purposes during installation. The Bentonite slurry displaced by the concrete will be pumped back to the desander. Hook the wire sling with shackles on to the main links.

The pile is driven far enough into the lower material to develop adequate frictional resistance. Laser level is set up for dippinglowering the top of reinforcing cage into the pile allowing for the 40 D factor and set for the cut-off level as opposed to relying on the piling platform level which can deteriorate over time to set the cut-off level. The specification of pile cut off level is as follows.

The engineer will provide a detailed drawing for pile cap shutter and the required supports such as jacks tie road. The unconcreted length empty boredrive between the specified cut-off and the commencing surface. Marking will be made on each pile periphery at pile cut off level and a cut with grinder will be made on the marking to prevent excess breaking of concrete below cut off level.
