What Is Civil Work?

Civil work refers to the foundational construction activities carried out before starting the interior design or renovation process. It includes tasks such as breaking and demolition work, masonry work, plumbing modifications, electrical changes, painting, polishing, and other structural adjustments. The exact nature of civil work can vary widely depending on the scope of the project, property type (residential or commercial), and client requirements.

Civil Work Before Starting Interior Design Process

1. Breaking Work: Laying the Groundwork

Breaking work is the first step in transforming a space. It involves removing existing structures, features, and finishes to prepare the site for new designs and installations.

When to Start Breaking Work in the Interior Design Process:

Breaking work is a step which involves demolishing existing walls, flooring, tiles, built-in units, or unwanted fixtures and should ideally begin only after the initial planning and design phase is complete.

1. After Finalizing the Interior Layout

You should begin breaking work only once the final interior layout, furniture plan, and structural requirements are approved by your designer or architect. This avoids unnecessary demolition or rework later.

2. Post Site Measurement and Structural Assessment

A detailed site survey and structural feasibility check should be done before initiating breaking. This ensures that no load-bearing walls or crucial utility lines are disturbed.

3. After Receiving Necessary Permissions

For apartments or housing societies, you may require society permissions or approvals from local authorities before any structural changes or demolition is carried out.

4. Once All Services Are Planned

Ensure that plumbing, electrical, and HVAC plans are aligned with the demolition scope. For example, breaking a wall with hidden plumbing lines can lead to water damage or delays.

5. Before Any Interior Work Starts

Breaking work should be the very first on-site activity after planning and before masonry, wiring, flooring, or any decor elements are installed. It sets the stage for clean, efficient execution of the interior work that follows.

Pro Tip: Always work with experienced civil contractors or an interior designer’s team for breaking work to avoid damaging structural components or utilities.

Expert Tip: For bathrooms, moisture-resistant ceilings protect against dampness while housing fixtures like exhaust fans and sprinklers.

3. Plumbing Work

Plumbing is the backbone of any residential renovation, playing a vital role in ensuring hygiene, functionality, and day-to-day comfort. Whether it’s a bathroom upgrade or a kitchen remodel, the plumbing team follows a structured, step-by-step process to ensure quality and durability across all water and waste systems. Here’s a detailed breakdown of the common plumbing workflow followed during home renovation:

Step 1: Initial Survey and Planning

The process begins with a comprehensive site walkthrough. The plumbing team inspects all relevant areas including bathrooms, kitchen, duct zones, and utility spaces. During this survey, existing issues such as leakages, corroded pipes, improper slopes, or low water pressure are identified and documented.

At the same time, the location of all fixtures (including WCs, wash basins, faucets, jet sprays, showers, water points, and washing machine connections) is mapped according to the finalized interior design. Based on this, a detailed material checklist is prepared. This typically includes CPVC pipes, diverters, angle valves, mixers, faucets, wall brackets, traps, elbows, and necessary sealing products.

Step 2: Removal of Old Fittings and Pipelines

Once planning is complete, the existing plumbing setup is dismantled. This involves carefully removing old sanitary fixtures such as toilets, basins, shower heads, kitchen taps, and utility fittings.

Outdated or damaged CPVC pipelines, diverters, and waste traps are also dismantled and removed. To ensure a safe work environment and prevent any water damage during the renovation, all active water lines are temporarily shut off and capped.

Step 3: Pipe Replacement and Re-routing

After dismantling, new CPVC piping is installed to handle hot and cold water supply across all zones. This includes laying concealed pipelines within walls and ducts, ensuring proper alignment and slope for uninterrupted flow.

Pipelines are also re-routed wherever needed to match the revised layout of fixtures like the WC, wash basin, washing machine, or kitchen sink. Additional connections such as flush valve inlets and outlets, geyser or boiler lines, and Aquaguard pipes are also installed or repositioned. If required, the domestic water line inlet is shifted or extended to support utility area changes.

Step 4: Installation of Sanitary Fixtures

With the pipework in place, new sanitary fixtures are installed across the home. These typically include floor-mounted or wall-hung WCs, wash basins with mixers, shower sets with diverters and spouts, jet sprays with angle cocks, kitchen faucets, and utility taps. Points for washing machine inlets and outlets, are also connected.

Each fixture is installed using high-quality threaded connectors, PTFE tape, and appropriate sealants to ensure a tight, leak-proof fit. Proper alignment, height, and accessibility are checked as per the design specifications.

Step 5: Testing and Final Adjustments

Once installation is complete, the entire plumbing system undergoes rigorous testing. Pressure tests are carried out to ensure that all joints, pipes, and fittings are leak-free. Water flow is tested from all key points — including bathroom showers, basin taps, kitchen faucets, and utility connections — to confirm consistent supply and water pressure.

Drainage is also checked to ensure that proper slope and flow are maintained, avoiding any backflow or water stagnation. If needed, fixtures are adjusted for height, alignment, or grip to achieve a perfect finish.

Step 6: Final Touches and Clean-up

In the final stage, all exposed joints are sealed using thread sealants or silicone for long-term durability. Wall plates, flange covers, and finishing accessories are fitted neatly to complete the look.

Any unused pipe openings are capped or sealed, and the site is thoroughly cleaned of dust, debris, and leftover plumbing material. The plumbing setup is now fully functional and ready for use, with a clean and professional finish.

4. Painting

Painting is one of the most transformative stages of a home renovation. It brings the space to life, reflects the chosen design palette, and creates the final visual impact. But achieving a high-quality finish involves much more than just applying color to walls. Here's a common step-by-step process that professional painters follow during home renovation projects:

Step 1: Surface Inspection and Planning

Before beginning any work, the painting team performs a thorough inspection of all paintable surfaces — including walls, ceilings, doors, and woodwork. They check for undulations, cracks, seepage, water damage, or previous layers of flaking paint.

Based on the site condition and the client’s requirements, the team finalizes:

• The type of paint to be used (emulsion, enamel, texture, or putty finish),

• The number of coats required, and

• The colors as per the approved design theme or color palette.

A material list is prepared including primer, putty, basecoat, topcoat, brushes, rollers, sandpaper, and masking tape.

Step 2: Surface Preparation

A clean and well-prepared surface is essential for long-lasting paint. This step involves:

• Scraping off old, flaking, or peeling paint layers using a putty knife or scraper.

• Filling cracks and holes using white cement, wall putty, or POP.

• Leveling surface undulations to ensure a smooth finish.

• Sanding the surface with emery paper to remove dust, dirt, and fine particles.

Electrical switches, flooring, furniture, or nearby surfaces are masked with tape or covered with sheets to avoid stains and drips.

Step 3: Primer Application

Once the walls are clean and smooth, a coat of primer is applied. Primer helps:

• Seal the surface,

• Improve paint adhesion,

• Enhance the durability of the final coat, and

• Prevent patchy or uneven absorption of paint.

Depending on the surface type (wall, ceiling, wood, or metal), an appropriate primer is used such as water-based wall primer, wood primer, or metal primer. After the primer dries completely, the surface is lightly sanded once again to remove minor roughness.

Step 4: Putty and Leveling (If Needed)

In many cases, after priming, a coat or two of wall putty is applied to fill in micro-level imperfections. This ensures a uniform base, especially when using lighter shades or matte finishes. Putty is allowed to dry naturally before being sanded for a butter-smooth finish. This step is crucial for luxury or textured paintwork.

Step 5: Paint Application – Basecoat and Topcoat

Now comes the actual color application.

• First Coat (Basecoat): The initial layer of the selected paint color is applied using rollers for walls and ceilings, and brushes for corners or trims.

• Second Coat (Topcoat): After drying the first coat, a second coat is applied to enhance color richness, depth, and uniformity.

• Third Coat (if needed): For deeper colors or heavy coverage, a third coat may be applied.

All coats are applied with even pressure, in uniform strokes, and allowed to dry as per the product's recommended time between coats.

Step 6: Painting of Doors, Windows & Trims

While walls dry, wooden and metal surfaces are painted using enamel or oil-based paints. This includes:

• Main doors, room doors, window frames, skirting, and moldings.

• Sanding, primer, and paint application is done in 2–3 coats.

• Door edges, hinges, and handles are masked for precision.

Step 7: Touch-Ups and Final Inspection

Once all coats have dried, the team performs a thorough inspection of the painted areas:

• Minor paint marks, roller lines, or touch-up needs are corrected.

• Masking tape is removed carefully to ensure crisp edges.

• Switch plates and hardware are reinstalled if removed earlier.

Step 8: Clean-Up and Handover

All plastic sheets, masking tapes, and protection covers are removed. The space is cleaned thoroughly to eliminate any dust, paint drops, or debris. Once complete, the freshly painted home is clean, crisp, and ready to enjoy.

Maintenance Considerations:

False ceilings require ongoing care to retain their appeal:

• Dusting: Use a microfiber cloth to clean surfaces regularly.

• Inspection: Periodically check for cracks or loosened joints, especially around cutouts for fixtures.

• Repairs: Address minor damages promptly to prevent them from worsening.

Importance of Civil Work in Interior Design:

1. Structural Stability: Civil work ensures the safety and durability of design elements, especially false ceilings and partitions.

2. Aesthetic Precision: A properly executed masonry base allows designers to achieve smooth finishes and sharp details.

3. Functional Integration: Accurate cutouts and reinforcements ensure the seamless integration of utilities like lighting, HVAC systems, and sprinklers.

4. Time Efficiency: Addressing potential issues during civil work minimizes delays in later stages of the project.
