This type of estimate is a little bit more accurate than above mentioned methods and mostly suitable for multi storied buildings. This type of estimate done by multiplying the volume of the building by the unit cubic rate achieved from the previously (also recent) estimate. Among that, areas which can include are,įloor area with area of walls at floor level excluding the offsets of the building, internal shafts of sanitary fittings within 2m2, lifts, air conditioning ducts, area of porch at floor level (cantilever part can’t be included), area of barsati – a room on the terrace or roof top with veranda outside.Īrea of lofts, open balconies / un enclosed balconies, fascia, towers which project above terrace level, louvers & vertical sun breakers.ĭocuments such as line plan with complete specifications & costs for services such as water, electricity should be attached with estimate. There are some restrictions in calculating the plinth area of a building and some area have to include or exclude when calculating. Plinth area rate = Total cost of a previously built building / Total plinth area of that building. Plinth area = plinth length X plinth width Plinth area estimate = Plinth area X plinth area rate. Plinth area rate is derived by dividing the total cost of a previously constructed building by plinth area of the previously constructed building. Simply it can be also stated as the roof covered area of a building. Here the plinth area is referred as, external plinth area of the building at floor level. Plinth area estimate can be achieved by multiplying the values of plinth length, plinth width & plinth area rate. Here the estimator already knows the rate for 1m 2 area & with that he/she calculates the cost estimate for the newly proposed area (of similar house).Īpproximate estimate = Rate of 1m 2 (already known value) X proposed area (m 2) Commonly the approximate estimate is calculated with relevant to the previous experience.eg: To calculate the estimate for a house, a previously (& also recently) completed similar house will be considered.

Documents such as project drawing plans, details about the land including electricity & water supply and a full clear report are necessary to carry out the estimate. To give a clear idea to the owner (client) about the amount of cost needed for the project and to get the approval from necessary sanctioning bodies (eg: from banks to get loan). This type of estimate is prepared in the initial stage of a project. It is also called budget, preliminary estimate. I am especially excited to work on the fire pit at the center, which I think will be a lovely addition to the ambiance of your backyard retreat.Types of estimate Type1: Approximate estimate –
