The detailed specification is a detailed description and expresses the requirements. The detailed specification of an item of work specifies the quality and quantities of materials the proportion of mortar. Workmanship. The method of preparation of work and excavation and the method of measurement the detailed specification of different items of work are prepared separately and describe what the works should be and how they shall be executed. Detailed specifications are written to express the requirement clearly in a consince from avoiding repetition and ambiguity the detailed specification are arranged as per order as the work is carried out the detailed specification of prepared properly are very helpful for the execution of work. The detailed specification form an important part of contract document.
Every engg. Department prepared, the detailed specifications on various items of work and get them printed in order book from under the name. Detailed specification when the work or a structure or project is taken up instead of waiting detailed specification every time the printed detailed specifications are referred.

GENERAL: -Snowcem consists of a base of white cement mixed with finely powdered coloring pigment to have the desired color and with addition of small quantities of ingredients. It gives a water proof surface snowcem is solid by manufacturer in 50kg drums. 25 kg drums & 5kg of various colors. The snowcem of desired color may be chosen.
MIXING : - Only fresh snowcem should be used .Hard or set snowcem should not be used .The content should be made loose by rolling and shaking the container before opening the container. First a paste shall be prepared by mixing 2 parts of snowcem powder with one part of water by volume &immediately this should be thinned by adding one another part of water to have a uniform solution of consistency of paint
