Ensure proper safety guarding of surveying equipment. To maintain the records of all surveying equipment handled. Survey Aide — Maintain and use Surveying equipment. Assist Surveyors in taking measurements, record measurements manually or electronically, and peg out boundaries. Equipment Operator — The only authorized person to operate any equipment to be used in the project. Rigger — The rigger assists in the movement of heavy equipment and loads to be lifted.
A rigger setups machinery and secures it in place and signal or verbally direct workers engaged in hoisting and moving loads, in order to ensure the safety of workers and materials. Mason — A Mason is a tradesman in building with units of various natural or artificial mineral products, as stones, bricks, cinder blocks, hollow blocks or tiles, usually with the use of mortar or cement as a bonding agent.
This also includes concrete plastering ability. Assist in constructing and later disassembling reinforcement braces, concrete forms, scaffolds and temporary structures. Note: All 3rd Party Certificates shall be inspected prior to commence work.
All machines shall fulfill Project Specification requirements if required. Aggregates Should meet the requirement in the project specifications.
Water Should meet the requirement mentioned in the project specifications. Lath, Beads, and Stops 1. Corner bead and edge trim shall be a minimum 4mm thick, rigid PVC plastic. Fixtures and Fasteners Nails, screws, and washers are to be stainless steel as indicated in the drawing.
Wire ties to be galvanized with a minimum diameter of 1. Bonding Compound Bonding compounds shall comply with the relevant provisions of BS Approved Mortar mix As per approved material submittal. Site Planning Refer to approved baseline schedule for the duration of plastering works. Preparation Contractor shall ensure that all gate passes, permits, tools, materials for safety precautions, manpower and equipment are available before commencement of work. The Site Team shall make sure that access roads are always clear from any obstruction and site is always accessible.
Site Clearance Before commencing the work, the area shall be cleared of all debris, materials or other obstructions. Required levels are to be confirmed and verified by Site Engineer and QC Engineer before commencing the work. It is the responsibility of the CM to ensure that any preceding activity is completed. Traffic Management Other than some special cases no special traffic management plan is required.
Special cases can be identified on individual bases and related actions can be taken accordingly. Pre-construction Safety Meetings The meeting shall be scheduled prior to the beginning of the work and before any Subcontractor starts on the project.
Traffic safety will be discussed to emphasize these meetings. Here, the plaster crumbles out, and the powdered mix falls down the adjacent floor.
The rise of moisture through the wall is caused due to the absence of a damp-proof course or bad site drainage issues or inadequate sub-floor ventilation. In this step, stop all the probable causes of the rise of dampness through the building walls. Some of the solutions are:.
After taking essential steps to fix the rise of dampness in plaster walls, the next step is to repair the plaster. Repairing the plaster without finding and solving the cause of plaster bubbling ends up with complete loss of work. This step includes the removal of bubbling materials, the peeled paint, crumbling paint materials, and the bubbling plaster. The wall surface after conducting step-1 must be cleaned using a stiff nylon brush and a shop-vac.
Note: Shop-vac is a special vacuum unit with a high-powered motor that helps to suck the debris, dirt, and chunk materials from the building sites and wood workshops. Wash the surrounding surfaces using a sponge and clean water. This process helps to remove any lime deposits. Once cleaned, allow the surface to dry before proceeding to the next step. Tip: For each coat, remember to reverse the direction of the application. Avoid building up the compound on the surrounding surfaces. Primer is generally applied before painting.
In plaster repair works, the priming process blocks the residual contamination present on the wall surface. It helps to get a proper bond with the patching compound. Primer also prevents the bleeding of the stains while painting. The primer used can be either an oil-based primer or a quick-dry primer-sealer. Gypsum plaster is widely used plasters material that can be mined naturally or produced as a by-product.
Usually clay plasters are applied in two coats, the first coat is 18 mm thick while the thickness of the second coat is 6 mm. Lime plaster is prepared by mixing equal quantities of lime and sand. The boiled solution of vine fruit in 3 litres of litres of water and a ratio of 1.
When the gypsum is heated to a certain temperature, the crystallization water supersedes a very fine powder of the pop. When water is added to this powder it sets immediately, the setting time being extended by adding some salts, some burnt ash and fine sand. A dry mixture of pop and sand is prepared on a platform, this mixture is taken in a small amount in a lee pan and appropriate amount of water is added.
This kind of plasters produces a very nice smooth finish with sharp edges and corners, it is not used for exterior surfaces. This plaster is an excellent decorative material, which is used on both interior and exterior walls. The first coat known as a rough coat, acts as a wall cladding provides the desired strength.
The second coat known as the finer coat gives the surface the desired shape and the third coat called the final coat gives the required texture, smoothness, and decorative appearance. It is a building material used for coating walls and chimney breast, its function is to replace the conventional gypsum plasters. It is required to protect the masonry wall from damp moisture thereby destroy or reduce wall moisture.
The plasters consist of a mixture of cement and sand 1: 2, pulsed alum is added at a rate of 12 kg per cubic meter of sand. Composite plasters is prepared by mixing cement, lime, pozzolana and sand in various proportions. The plasters are applied on the exterior or internal surfaces in various thicknesses in a single or two coats as required. Special mix plasters are required to provide decorative features to the surface of the walls and for particular functions such as waterproofing , restricted drainage, etc.
Plaster provides a decorative function where required; it is manufactured from three coats with a thickness of 25 mm. The first coat 10 mm thick, is called a scratch coat, the second coat is 10 mm thick known as the brown coat.
