CW Milestone – Part 7 - Boundary wall

Boundary wall is provided on a greenfield telecom site for safety purposes. Sometimes instead of boundary wall a steel fence can also be provided based upon agreement at the time of bidding or on a later stage. Steel fence will be discussed at a later stage. At some places it is more convenient to use concrete blocks. Same guidelines can be helpful with appropriate modifications.

The backfilling of the compound would be done in layers up to the required level. Approved backfill material would be used to get the desired compaction.

Construction of boundary wall is then made on the edges of leased area. Any of the three options like, reinforced brickwork wall, pre-cast boundary wall and galvanized fence can be adopted. Barbed wire is then installed on the wall for security purposes using turn-buckles to tighten it. Meanwhile the gate (hot dip galvanized) is also installed on the entrance to site.

During the construction of reinforced brickwork boundary wall following points should be checked.

• A-Class bricks would be used.

• Alignment of area should be correct as per drawings.

• Brick Fog portion should be in the upward direction.

• Bricks should be properly soaked before application of mortar.

• Verticality should be checked after placement of every three layers of bricks.

• Ask mason to tie a string around the first stake and loop it around the rest of them until bricks are being laid to the last one, where the string is being tied off. This helps to keep the boundary wall straight and keeps the bricks at same level.
