Application of lean construction principles and practices to enhance the construction performance and flow
(Ceylon Institute of Builders, 2015-06) Madanayake, UH; Sandanayake, YG; Fernando, NG; Karunasena, GI
Lean thinking has now become a radical philosophy that has permeated and expanded in to several sectors other than just manufacturing. The concept of Lean thinking evolves the optimization of work flow related functions and the possible outcomes with its contribution to sustainable construction. Correspondingly, application of lean theories and principles in to construction sector has the potential to improve the quality of work, aggravate the function related effectiveness, minimize the cost components/ waste and increase the overall profit in both strategic and operational levels. Apparently, it appears that the lean techniques have immensely contributed for many possible cost reductions compared with the traditional project management techniques. However, few barriers for the implementation of lean principles are also on the contrary. The research aims to investigate the effects of Lean Construction applications while identifying the prevailing barriers related to the same. The research has exploited qualitative methods to explore the aforementioned research question. This paper presents an exploratory study from extent literature, predominantly based on a case study of a project management organisation whereas the arguments were strengthened and underpinned by the formation of a conceptual framework to explore the contribution of implementing lean construction techniques in sustainable construction. The research findings would ultimately help different stakeholders on applying lean theories in to practice.

Sustainable implications of building reuse and adaptation
(2014-06) Madanayake, UH; Manewa, A; Sandanayake, YG; Karunasena, GI; Fernando, NG
Built environment products and processes are now biased more towards profitable markets while giving sustainability the first priority in achieving the same. Consequently, value has become one of the main concerns while seeking various cost reduction methods through sustainable implications. Building reuse is one distinctive way that reflects the aforementioned sustainability in multiple ways. The existing building stock in the UK does not support sufficient flexibility that can be used for future adaption. Demolition of those buildings and construction of new builds does not seem to be an optimum solution, unless it helps increasing the building redundancy. Thus, an effective and achievable solution is required to address this problem. Apparently, design for adaption and application of adaptable features from the initial stage of every new build seem to be the most sustainable way that can be endorsed with sustainable, flexible buildings that last long and resist the future potential changes. The research has exploited qualitative methods to explore the aforementioned problem. The research itself is based on a case study of Liverpool City Centre. Ten Structured interviews were conducted to identify the sustainable implications of building reuse and adaptation while an Archival Analysis was undertaken to identify the patterns of building change of use and their ability to reuse. The findings illustrate that economic factors have immensely influenced towards building reuse and adaptation. The research findings would also help different stakeholders to make decisions on how reusable features could incorporate within the new building designs through sustainability.
