1. Pre-Construction Protection Work

Construction protection is an essential step before starting any project to ensure the site and existing facilities are not affected by the construction process.

Ground Protection: Lay protective mats or carpets to prevent damage to the existing flooring.

Wall Protection: Use plastic sheeting, tape, or corner protectors to safeguard the walls.

Door and Window Protection: Install protective boards or seals to avoid scratches or paint contamination.

Furniture and Equipment Protection: Remove movable items from the site, and cover immovable items with dust sheets.

Dust and Soundproofing: Install temporary partitions or plastic curtains to prevent dust spread or noise from affecting the surrounding areas.

2. Pre-Construction Work for Tiling

Tiling mainly involves the construction of walls, floors, and ceramic tiles.

Measurement and Layout: Check the design drawings, mark the wall and floor positions, and ensure accurate dimensions.

Surface Preparation: Clean the floor and walls, remove dust, debris, or old materials, and repair any cracks if necessary.

Waterproof Testing: Install the waterproof layer and conduct a water test to ensure no leaks.

Material Preparation: Prepare cement, sand, tiles, and waterproof coatings, ensuring material quality meets standards.

Weather Considerations: Be mindful of the weather conditions, avoiding construction during high humidity or low temperatures.

3. Pre-Construction Work for Plumbing and Electrical Work

Plumbing and electrical work requires precise planning and installation to ensure proper functioning.

Design Confirmation: Confirm the positions and routes for wires, outlets, lighting, and pipes based on the design drawings.

Trenching Plan: Mark the areas on the walls and floors that need to be trenched, ensuring they do not conflict with structural beams and columns.

Equipment Inspection: Check that the embedded electrical boxes, water pipes, and electrical conduits comply with construction standards.

Material Inspection: Inspect the water pipes for leaks and ensure the electrical wires' insulation is intact.

On-Site Testing: Conduct water pressure and electrical power tests before construction to ensure system stability.

4. Pre-Construction Work for Carpentry

Carpentry typically involves the construction of furniture, ceilings, doors, and windows.

Blueprint Confirmation: Thoroughly read the design drawings and mark the details for carpentry work.

Material Preparation: Inspect the size, quality, and moisture content of the wood to ensure it meets requirements and prevent deformation.

Site Cleaning: Remove any debris from the site to provide a flat working space for carpentry.

Structural Measurement: Measure the dimensions of the construction area to ensure they match the site conditions.

Tool Inspection: Check the operation of tools like saws, drills, and other carpentry tools.

5. Pre-Construction Work for Painting

Painting work mainly involves the treatment of walls and wood surfaces.

Surface Inspection and Repair: Inspect the wall for flatness, repair any cracks or holes, and sand the surface.

Dust Control: Ensure the construction site is clean to prevent dust from affecting the paint finish.

Material Preparation: Confirm the types and quantities of paint, primers, and thinners to be used.

Masking: Use tape and dust sheets to cover areas that should not be painted.

Environmental Check: Control the temperature and humidity in the construction area to ensure proper paint application.

6. Pre-Construction Work for Plastering

Plastering is a crucial step for wall leveling and preparation for subsequent painting work.

Surface Preparation: Clean the walls, removing old paint layers, dust, or stains.

Crack Repair: Fill wall cracks with filler paste to prevent future cracking.

Material Preparation: Check that the putty powder is smooth and free of lumps, and mix it in the correct proportions.

Measurement and Leveling: Use a level to measure the flatness of the wall and mark areas that need to be filled or smoothed.

Test Scraping: Test scrape a small area to check the adhesion and effectiveness of the material.
