STUDY ON MODERN METHODS OF CONSTRUCTIONS USED IN SRI LANKA

Abstract

With the end of world war two, the demand for building construction increased together with inadequate supply of traditional constructions. To cater the increased demand the modern methods of constructions (MMC) came to practice as it yields high quality and less construction time. Nowadays the off-site MMC play a significant role in construction industry worldwide in terms clients’ fundamental needs by restraining problems in traditional brick, block constructions. However, the application of MMC seems limited and few building constructions have used MMC in the Sri Lankan construction industry. This research therefore aims to explore current practice of off-site MMC in Sri Lankan construction industry and identify the barriers in adopting MMC. Questionnaire survey has been carried out among 33 respondents including engineers, quantity surveyors and project managers to identify the applicability of off-site MMC and barriers in using off-site MMC. Data which have been gathered through the questionnaire survey have been analysed through statistical analysis and investigated that volumetric constructions are mostly used for single storey temporary buildings, hybrid constr uctions are mostly used for single storey office and temporary buildings while panelised constructions are highly used for single storey industrial and temporary buildings and sub-assemblies are mostly used single storey office and commercial buildings. Furthermore main barriers in implementing all above mentioned methods are public perception and poor awareness.
