Modular ceilings are among the last equipments to be installed at the site because it is a pre-finished product. Therefore, the building is expected to be in suitable condition, with regard to humidity, cleanliness etc., before installation of modular ceiling begins.

Sufficient information shall be clearly indicated on the drawings to enable the ceiling module and setting out points in each ceiling area applicable to all relevant trades to be established early.

The ceiling height in each area shall be marked in relation to the elevation bench marks and then transferred by means of water level.

When the hangers cannot be installed at the recommended dimensions, an appropriate suitable sub grid will be installed based on the site dimensions.

Hangers to be installed will be vertical or nearly vertical and shall not press against insulation covering ducts or pipes. If hangers have to be fixed diagonally to avoid obstructions the horizontal force shall be offset by bracing.

Leveling of the main runners shall be done with the supporting hangers. This will prevent downward movement when tiles are loaded

To ensure proper levelling, any bending of the material will never be undertaken.

The main runners shall be suspended by means of a GI wire of 2/2.5mm diameter or 4mm rod at every 1.2m and not more than 150mm from the spliced joints.

The last hanger at the end of each main runner should not be more than 450mm from the adjacent wall.

The loops shall be sharply bent and tightly wrapped to prevent vertical movement of the runner within the loop, wherever it passes through the main runner.

The wire shall be wrapped around itself a minimum of the full turns within a 3 inches length.
