Measurement of Materials and Works The rules for measurement of each item are invaribly described in IS- However some of the general rules are listed below. Measurement shall be made for finished item of work and description of each item shall include materials, transport, labour, fabrication tools and plant and all types of overheads for finishing the work in required shape, sizeandspecification.
In booking, the order shall be in sequence of length, breadth and height or thickness. Sametypeofworkunderdifferentconditionsandnatureshallbemeasured separately under separate items. The bill of quantities shall fully describe the materials, proportions, workmanships and accurately represent the work to be executed.
In case of masonary stone or brick or structural concrete, the categories shall be measured separately and the heights shall be described: Thequantitieslikeearthwork,foundationconcrete,brickworkinplinth and super structure etc. Inthismethod,thewallalongthelengthofroomisconsideredtobelong wallwhilethewallperpendiculartolongwallissaidtobeshortwall.

The skill, suitability and wages of local laboures areconsideedwhilepreparingthedetailedestimate. The process of working out the cost or rate per unit of each item is called as Data.
In preparation of Data, the rates of materials and labour are obtained from current standard scheduled of rates and while the quantities of materials and labour required for one unit of item are taken from Standard Data Book S. B Item No. The requirement of mateials are taken strictly in accordance with standard data book S.
The cost of these includesfirstcost,freight,insuranceandtransportationcharges. Some works need special type of equip- ment, tools and plant. Preliminaryorapproximateestimateisrequiredforstudiesofvariousas- pects of work of project and for its administrative approval.
