    Work Package Received:

    WP should be approved by TP Design .

    Thorough study of WP before CW kickoff

    SITE KICK OFF:This is the first and most important step for the BTS

    site construction.

    Following Points are observed.

    Coordinates matched with SAR.

    Lean Concrete

    Function of Lean concrete to provide a plane and level plate formand its the base of whole structure.

    Steel Fixing

    It should be of specified Grade.

    It should be free from rust

    Back Filling & Compection

    Back filling is very important, if its not done

    properly it can cause settlement.

    TOWER INSPECTION:

    Torque check to be done for all bolts both for maximum andminimum torques.

    All braces and joint plates should be properly seated there shouldnot be any gap b/w two overlaying members.

    Galvanization should be up to standards.

    Fall arrestor should be properly installed.

    There should be no rust on tower components.

    At least two threads of each anchor bolt should be exposed.

    No extra holes be present in tower main legs or braces.

    Lightning arrestor should be installed on the opposite side of BTS.

    ACWL should be installed and commissioned.

    Climbing ladder and rest platform installed and secured properly. No member/bolts should be missing.

    All four legs of the tower should be connected to the earthing ringburied underneath.

    Generator & Fuel tankInstallation/Inspection:

    DG set must be of required rating.

    Vibration dampers rubber pads should be provided undergenset body.

    The exhaust of generator should not be interfering andpointing outward not toward the equipment.

    Check for any fuel, water or oil leakage inside.

    DG set must be grounded both internally and externally. DG set counters (hour meter, frequency meter, voltmeter

    and oil pressure gauge )

    Fuel alarm cable should be connected.

    Cables arrangement should be proper inside the canopy.

    No evidence of leakage and corrosion in any part of fueltank.

    Fuel tank gauge should be serviceable.

    Check the cycle of transfer from main power source toemergency.
