Grey Structure Construction

The grey structure phase focuses on the skeleton of the building, preparing it for finishing works.

Site Preparation and Excavation:
- Clearing the site and marking boundaries as per site plan.
- Excavation for foundations, ensuring proper depth as per structural design, and dealing with site-specific challenges (water tables, soil type).
Foundation Work:
- Laying the footings or piles and pouring reinforced concrete (RC) foundations.
- Waterproofing is often applied at this stage to protect the foundation.
Superstructure (Columns, Beams, and Slabs):
- Formwork is set for beams and columns, and concrete is poured as per structural reinforcement detailing.
- Steel reinforcements are laid for slabs, followed by concrete pouring and curing.
Masonry Work (Walls):
- Laying of bricks or concrete blocks to form walls. Care is taken to ensure they’re level and aligned with door/window frames.
- Damp-proofing and insulation layers are added during this stage.
Rough-in for Electrical & Plumbing:
- Electrical conduits are installed inside the walls, and pipes for water supply/drainage are laid before plastering.
- Ensuring correct placement of outlets and switches to avoid conflicts with later finishes.
Roof Slab Construction:
- Laying of the roof slab or other roof structures (such as steel trusses), followed by waterproofing the roof.
Plastering:
- Cement plaster is applied to internal and external walls, smoothing the surfaces for future finishes like paint or tiles.
Floor Screeding:
- A layer of concrete is applied to floors to level them, preparing for tiling or other floor finishes.
