7.0. METHODOLOGY
7.1. WORK METHODOLOGY & SEQUENCE OF WORK
7.1.1. Fixing conduits in the slabs.
7.1.2. Fixing conduits with GI boxes in the columns.
7.1.3. Fixing conduits with GI boxes in the walls.
7.1.4. Fixing Enclosures for Distribution Boards.
7.1.5. Wiring for lighting, & Power Points.
7.1.6. Fixing Cable Tray/Ladder.
7.1.7. Laying of L.V. feeder Cables.
7.1.8. Fixing D.B & SMDB Modification
7.1.9. Fixing wiring accessories & Light Fixtures.
7.1.10. Telephone / Data System.
7.1.11. Fire Alarm System.
7.1.12. Low Current System.
7.2. Conduits in the Slabs.
In this stage, we have to start our work directly after fixing the shatter, since there is a lot of work to be done before fixing the steel, Determine the exact placement of lighting fixtures, power outlets, and fire alarm points. Secure junction boxes at designated locations to house electrical connections.
Drill the necessary holes to accommodate electrical conduit leading to switches, bells, and break-glass pull stations. And DB’s. After finishing the steelwork, we will start fixing our conduits as per the approved shop drawings, of course, we have to avoid passing the conduits in the wet areas, minimize conduit bends, and securely fasten them to the steel structure. Utilize expansion couplers at locations with expansion joints.
At the end, we will use masking tape to close all the end openings of the conduits.
7.3. Fixing Conduits and GI boxes in the columns.
Before casting any column in the site, we have to check if there is any Switch Socket, bell, or broken glass fixed on the column. If there is any, we have to fix the GI or PVC box properly so that it will be touched with the shatter. Conduit installation within the column will be extended to the top.
7.4. Fixing Conduits and GI boxes in the walls.
Upon completion of masonry work on each floor, we will proceed with marking the designated locations for electrical devices (switches, sockets), telecommunication (telephone outlets), and entertainment (TV outlets). This will be done by the approved construction drawings. Then we will start chasing and chipping the marked locations by using the grinder, accordingly, we will fix the GI boxes with a minimum of 5 mm away. We'll ensure the GI boxes are positioned flush with the wall surface before plastering. The following day, we'll complete the conduit terminations by connecting them to the GI boxes."
7.5. Fixing DB’s Enclosures.
Usually, we always inform the main contractor, before starting the block work to use a block of 200 mm. width instead of 100 mm. and to locate plaster level points only in the location where recessed DBs, so that we can fix the enclosures properly and ensure the enclosures are completely flush with the plaster. The mounted height of the enclosures will be 1300 (bottom of the panel).
The distribution board will be aligned, leveled, and securely fastened to the wall.
The surface-mounted panel boards will be fixed at least 25 mm from the wall: ensuring supporting members do not prevent the flow of air.
Distribution board interiors will not be installed in cabinets until all conduits and Connections to the cabinet have been completed.
Trim for flush-mounted cabinets will be installed in a plaster frame, flushed with the furnished wall. Trim will be installed plumb and square to finish the paintwork.
