What is Analysis of Rates or Rate Analysis of Civil Works?

Every construction project is divided into number of activities. Each activity consists of different types of civil or construction works. For example, the in the construction of a building, the activities can be excavation or earthwork, Concrete work, masonry work, Wood work such as doors and windows, plumbing, flooring, waterproofing, finishing work such as plastering, painting and distempering. The Activity earthwork can be divided into many types based on depth and type of soil. For example, an excavation of 1.5m deep in soft soil, an excavation of 3m deep in hard soil. Likewise, concrete work can be divided into many types based on its mix proportions and its placement. For example, M25 reinforced concrete work in foundation, M30 reinforced concrete work in columns, slabs etc. Likewise, there can be many small civil works in every construction project. The cost of any construction project is calculated based on each works associated with every construction activity. Thus it is essential to calculate cost of each small works. Rate analysis of Civil Works or Building Works is the determination of cost of each construction work per unit quantity. This cost includes the cost of materials, labours, machinery, contractors profit and other miscellaneous petty expenses required for the particular work to be complete in unit quantity. For example, cost of 1 cubic meter of M20 RCC work in slab, Cost of 1 cubic meter of excavation in soft soil of 1.5m depth, cost of 1 square meter of plastering of 20mm, cost of 1 square meter of painting work with specified paint in 2 layers or 3 layers as required. The cost of materials in rate analysis is calculated as combination of cost of material at origin, its transportation costs, taxes. The rate of labour is based on skill of the labour, such as skilled labour, semi-skilled and unskilled labour. The cost of materials and labours vary from place to place. Thus, the cost of each construction work varies from place to place.

What are the Factors Affecting Analysis of Rates of Civil Works?

Factors which affect the rate analysis of civil works are:

What are the Elements of Rate Analysis of Civil Works?

Elements which constitute the rate analysis are: a) Material cost inclusive of wastage b) Labour cost c) Plant & machinery owning and operating charges d) Water charges e) Taxes f) Insurance/ risk coverage charges g) Contractor’s overheads and profit
