If, on the other hand, we are going to use a sub-contractor to perform all of the activities, we would use the unit rate from the subcontractor and only add items 13, 14 and 15. The subcontractor, though, would calculate the unit rate inclusive of all the items from 1 to 15. The item unit rates are very much affected by the labour productivity ...

A unit rate can be described as the monetary value allocated to a unit of measurement for a given item in a bill of quantities, according to the Royal Institute of Chartered Surveyors (RICS). This can be the cost per square meter of floor area, cost per kilogramme of steel ...
To find the unit rate, divide the total quantity by the number of units, and simplify if needed. For example, if 1212 apples cost $6, $6, the unit rate is $6 ÷ 12$6 ÷ 12 apples = $0.50= $0.50 per apple. You can also set up the ratio as a fraction, then divide the numerator by the denominator and simplify.
When estimating using unit-rates, you identify all activities within a project and determine the number of hours and amount of material needed. From there, you assembly those items into large components to add structure to the estimate and to simplify the search for specific items later on. This way of estimating is called bottom-up estimating.
Unit rate is the ratio of two different units, with denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc. Arithmetic is probably the most basic and ancient branch of mathematics and is quite commonly used in our day-to-day life. This subject is all about the problems based on numerals and operations upon numerals.
Definition. A unit rate is a ratio that compares a quantity to one unit of another quantity, expressing how much of one item corresponds to one unit of another. This concept helps simplify comparisons between different ratios by providing a clear measurement for every single unit, making it easier to understand and analyze proportional ...
