Electrical Estimating is not just plucking figures out of the air; it is a process with proven functions and calculations which take into account not only material prices but also the productive efficiency of the total business.
Each and every Electrical Engineering and Contracting Business is different with one major variable function called human resources.
The basic principle is establishing labour units, is to provide a separate unit of labour for the installation of each item of material for the conditions under which it is being installed. The more completely the overall operation can be broken down into individual units, the more accurately the total estimate labour can be determined for any given job.
In Electrical Estimating as a starting point the human resource function requires basic labour units that have been proven on past projects over time on the productivity of human resource for different functions (eg installing a light).
Each organisation has different efficiency levels depending on the make up and experience of the human resource on the particular functional outcome at the time of execution; the basic labour units will need to be updated regularly through a feed back loop from current projects as the make up the human resource changes over time in organisations. The efficiency level depends on the number of workers having the required skill level for each particular task.
Already set-up there is a material catalogue with a library containing thousands of electrical items and components having proven labour units attached at www.theelectricalestimator.com.au/contract-estimating
