METHOD STATEMENT FOR MEDIAN & ISLAND FILLING

                                  MEDIAN & ISLAND FILLING                         

1. Scope:

   This work shall consist constructing of median in the road dividing the carriage way in to separate lanes to channelize the traffic in accordance with the lines, grades and cross sections shown on the drawings.

2. Reference:

Section 407 of MoRT&H specification.

3.  Equipments:

~ Dumpers, Motor grader/Loader, Roller/Plate compactor, Wooden Rammer, and Water tanker

4.  Materials:

  The materials used in the median shall be soil, moorum, gravel, recycled material, a mixture of these or any other suitable material approved by the engineer. Such materials shall be free of logs, stumps, roots or any other materials likely to deteriorate the stability of the median.

  The materials shall satisfy the Physical and chemical requirements as per MoRT&H Clause No: 305.2.1.1, 305.2.1.2, and 305.2.1.3.

5. Procedure:

~ Unwanted plants, roots, boulders, concrete and bituminous material shall be removed and got checked by raising RFI prior to start of median filling.

·  Place/Dump the approved borrow material or any other suitable material approved by the engineer in the median by dumpers. In case of Existing road in used after ensuring road safety by placing barricades 50m before the spot with adequate information sign boards and markings.

     Care shall be taken to avoid spilling of soil over adjacent pavement while dumping.

       Soil shall be spread in uniform layers of 200mm using motor grader, Dozer, loader or manually as per the site condition.

~   Water shall be added to the material to achieve the moisture content in the range of +1 % to -2% of OMC before rolling takes place.

~   Compaction shall be done with 8-10 Ton roller in 4.5m median where as in 2.5m median compaction shall be done with 2.5 ton roller or plate compactor for 1.2 m median.

~    The top most layers shall be compacted lightly in order to facilitate sufficient growth of roots of grass and plants/shrubs.

               The filling shall be raised centrally by 3% on either side for easy flow of              rainwater to the adjacent pavement and avoid any water logging in median.

6. Safety Precautions:

~ All dumpers shall be provided with reverse horn & light.

~ Wherever required, Flagman shall be provided.

~ The speed of construction vehicles plying in stretch shall be restricted   to 30kmph. Any labour, if being used in the job shall be screened and trained.

~All workmen at work area shall wear PPE^·s and reflective jackets.

~ Median filling work shall not disturb the live traffic.
