Under IS 1200 Part 15 (1987), surfaces with uneven textures like trellis and louvred joinery are measured by taking the flat overall area including frames, edges, and cleats, without deducting for open spaces. The equivalent plain area for painting is calculated by multiplying the measured flat area by specific factors: 2.0 for trellis work and 1.8 for louvred joinery. This method ensures the complex surface contours are accounted for accurately.
Per IS 1200 Part 15 (1987), the following multiplication factors adjust the flat measured area to account for surface irregularities: 14% increase for corrugated sheets (multiply by 1.14), 10% for Nainital pattern roofs with plain sheets (multiply by 1.10), 25% for Nainital pattern roofs combined with corrugated sheets (multiply by 1.25), 20% for corrugated asbestos cement sheets (multiply by 1.20), and 10% for semi-corrugated asbestos cement sheets (multiply by 1.10). These factors ensure precise estimation of paint quantities on textured surfaces.
Yes, IS 1200 Part 15 includes preparatory operations such as knotting, priming, stopping, rubbing down, burning off, and stripping as integral parts of measurement. These must be itemized and described separately in the estimation. The number of coats applied and the condition of previously painted surfaces are also specified to ensure comprehensive quantification of finishing work.
Painting on fabricated steel and iron under IS 1200 Part 15 is measured by including the priming coat within the fabrication cost, while subsequent coats are quantified separately based on either the weight or surface area of the steel/iron components. Additional elements like rivet heads, bolt heads, and nuts are counted as extra items if painted in different shades. The measurement distinguishes between flat and girthed surfaces and employs multiplying factors for uneven surfaces to convert to equivalent plain areas.
Indeed, IS 1200 Part 15 prescribes that small painted items up to 0.1 m² are enumerated individually rather than measured by area. Repair painting up to 1 m² is categorized into three size groups and also enumerated accordingly. Larger painting areas are measured in square meters, with adjustments for uneven surfaces made through multiplying factors from the standard’s tables, ensuring consistent and fair measurement practices.
