The 1977 edition of IS 1200 Part 11 delineates standardized procedures for quantifying paving, floor finishes, dado, and skirting tasks within building and civil engineering endeavors. It outlines comprehensive measurement protocols for diverse materials including tiles, slabs, blocks, and in situ finishes such as terrazzo and granolithic. This code is pivotal for professionals like quantity surveyors, civil engineers, and contractors to achieve precision and uniformity in material measurement for cost estimation and invoicing.

IS 1200 Part 11 addresses measurement methodologies for paving and floor finishes incorporating various materials such as granolithic, terrazzo, mosaic, and other related types. It requires detailed information on composition, thickness excluding keys and grooves, number of coats, surface treatments like steel trowelling or polishing, base characteristics, and installation locations including flooring, dado, and skirting. This classification aids in precise measurement and specification of different flooring materials.
Per IS 1200 Part 11, bedding and backing for skirting are measured distinctly in running metres, corresponding to the skirting’s length and height, whereas for dado, these are quantified separately in square metres aligning with the dado’s surface area. All returns, mitres, and stops are incorporated within the main item measurement. Cutting and fitting around fixtures are enumerated separately in increments of 25 cm girth to maintain accuracy in quantity estimation and billing.
IS 1200 Part 11 specifies that square cutting at joints and edges is included within the item measurement except for certain exceptions. Raking and curved cuts are to be measured separately in running metres unless they occur within a pattern. For diagonal patterns, boundary perimeter cutting is measured linearly. Rounded external and coved internal angles are also quantified separately with girth specified. Floors laid in bays or panels require the bay size to be stated with dividing strips measured individually. Screeded beds beneath finishes are described and measured separately to ensure clarity and uniformity.
According to IS 1200 Part 11, cutting and fitting around fixtures like ducts, brackets, newels, WC pedestals, vents, and soot-doors must be enumerated by measuring the total girth or perimeter in increments of 25 centimetres. This grouping facilitates accurate quantification of the cutting and fitting work required around such elements, enabling precise costing and clear documentation.
When detailing precast tile or slab units in compliance with IS 1200 Part 11, the description must include the type of unit (such as precast concrete with specified mix, terrazzo, brick, or natural stone), precise thickness and size, shape especially if non-rectangular, surface finish like glazed or polished, fixing methods including bedding, joint treatments such as grouting or pointing, the nature of the base (wood, concrete, screed, brickwork), location of use (flooring, dado, skirting), and joint layout or pattern. Additionally, temporary moulds, composition and mix details, and base treatment must be specified to ensure correct measurement and execution.
