Life Cycle Cost Awareness in Bhutanese Construction Industry

A book published. Self-authored. Go through the abstract. Thank you. 

Significant knowledge gaps exist in the knowledge of Life Cycle Costing and the alternative selection of building materials in the construction industry. In order to fulfill the gaps a questionnaire survey was developed for 319 respondents using the Life Cycle Costing for the Bhutanese construction industry. Life Cycle Cost Analysis of selected components of the selected building was done taking into account relevant economic factors: initial costs, maintenance, and operational costs.

The maintenance and operation expenses are generally ignored in the building industry, especially in the design stage. For this research, the method of LCC, the present worth cost approach, was evaluated with a projection of building service life as 60 years, an inflation rate as 9.07%, and a discount rate as 0%.

About 52% of the respondents do not have an idea about LCC when making investment decisions, nor do they take maintenance, operation, and replacement costs into consideration. The lack of significant input-cost data and lack of experience appear to be the most important problems, supported by 78% who responded lack of experience and 62% who responded lack of significant input-cost data.

The LCC analysis showed that ceramic tiles, pre-painted CGI sheets, and LED lamps have the lowest life cycle costs among the many material alternatives available in the market, that is, 16% for LED lamps, 13% for ceramic tiles, and 64% for pre-painted CGI sheets.
