Investigation on elements and their fraction of housing construction cost

Abstract

Construction industry is predominantly projected cost based. Project cost can be identified as one of the main constraints of any kind of construction projects. Construction cost is the major portion of the project development cost. And yet every construction organization struggles to estimate the actual construction cost accurately prior to the construction. All stakeholders such as client, contractor, Quantity surveyors, engineers etc. try to estimate the construction cost with limited data available. This research study focused on the derivation of empirical relationships for each cost elements in construction cost of two-storied houses. The investigation is based on the previously prepared bill of quantities of two storied houses which gathered 45 number of bill of quantities for the analysis. This study sensitively analyzes the variation of cost according to the type of the house using footprint of the house as the variable parameter.
