Sequence of Work for Street Light Foundation Works

Reinforcement & Formwork Fabrication:

Ensure all of the reinforcement to be used shall be free from grease and oily materials

The Cut and bend up reinforcement bars for the street light foundation shall be placed as per the approved drawings, necessary overlaps shall be provided as per the approved drawing and general notes wherever applicable.

Street Light Pole Foundation Construction Method Statement

Enough cover to the reinforcement shall be maintained throughout the structure as per the approved drawing.

Sufficient cover blocks, spacers shall be provided to maintain good cover to all the reinforcement placed.

Cover blocks shall be tied properly to arrest the displacement from their defined original position.

Floating form work for the collars shall be placed as per the drawing, with adequate supports to the anchor bolts to keep in position, line and level.

Excavation for Street Light Foundation:

Before starting the excavation the area of the excavation shall be backfilled as per the specification and well compacted to avoid collapse of the drill hole while / after excavation.

With respect to the location provided by the surveyor using excavation shall be done to the required size and level of Street Light foundation.

The excavated soil shall be stocked away from the drill hole to avoid collapse inside the drilled hole.

Upon completion of the excavation the excavated material shall be disposed to the designated location.

Ensure the drill hole is stable and no loose material is present aside.

Dewatering:

while excavation through Agor in high water table areas the ground water may be encountered.

Drilling can be continued until the required depth of foundation is reached.

Rebar shall be erected followed by the form work and anchor bolts erection in the drill pit with water stagnation itself.

Once the erection of rebar is completed dewatering shall be commenced just before pouring the foundation concrete.

Upon the dewatering is completed and the pit is dry sweet water shall be used to wash the rebar in contact with the ground water before concreting, and the concrete pour shall proceed only after washing and removing the excess water only.

Concrete Mix Design:

Ensure that the concrete mix design used is approved by the consultant.

Prior to the the placing of concrete, ensure the concrete receiving surface is free from dust and other foreign materials.

Ensure inspections and approvals are obtained for Reinforcement, and utility services are approved through RFI (As per ITP) prior to the placing of concrete. As per approved ITP.

Ensure the Ambient temperature shall be less than 400C and the concrete temperature shall be less than 320

After obtaining the necessary permission to place the concrete, the pouring shall commence from the trans mixer to the foundation.

The compaction of concrete using needle vibrators shall be done properly to cover the entire area. Excessive vibration shall be avoided.

Necessary Quality control inspections and Concrete Cubes casting shall be done as per the approved ITP and documented.

After two hours of concreting the floating collar shutters shall be removed otherwise once the concrete is harden removal of shutter will be difficult and may damage the collar portion of the concrete.

The cast concrete element shall be either water cured with wet hessian cloth for seven days or by approved curing compound on the exposed collar portion only.

Grouting and finishing

Once the street light poles are erected the gap in between the base plate and the concrete foundation shall be grouted with approved grouting materials, shutters shall be used to achieve the required shape as per the approved drawing.
