The construction industry plays a major role in country's economic growth. Providing efficient service and quality output are the major challenges that are often faced by the industry. Unnecessary cost and wastage always occur while handling construction projects. It was identified off- cuts from cutting materials and other design considerations are the main causes of waste generation. Modular Coordination (MC) is found to be an essential concept in minimum on-site modification and materials wastage. The objectives of this research were to investigate the existing practice of the use of MC, its benefits, implications and application in the material management process in terms of building industry. The objectives were comprehended by a comprehensive literature search, questionnaire survey and semi structured interviews among architects and contractors. Severity Index technique and Kendall's Concordance test methods were used to analyze the questionnaire. The results revealed that the application of MC is very poor in local construction industry and it is not up to the required standard. Glass and tiles are identified as the most suitable materials for applying MC. Though, there are different perceptions, the results suggested, MC facilitates sustainable benefits towards waste minimization and increases efficiency of productivity in the construction industry. Further, it would be more successful through a good collaboration among each party including manufacturers/suppliers

From recent past it is evident that Sri Lankan construction industry has inflated in to a distinct level along with the elevation of foremost human needs due to globalization and open economy. Owing to the unique nature of the industry, professionals are keen to find more sustainable approaches to bring out an enhanced end product. Project Management is one of the critical approaches in this regard. Concerning the immense finance investing in construction projects, all clients would seek on value enhancing to acquire added worth for their money, whereas cost monitoring and controlling along with project management tools/ techniques utilize to achieve these objectives becomes a foremost concern. Hence, the empirical study was carried out based on the research problem of “What are the practical barriers that the Sri Lankan contractors faced in usage of project management tools/ techniques by manual methods for their post contract cost monitoring and controlling practices in the way of achieving effective construction project cost management?” Primary data collected through interviews were analyzed using content analysis qualitative research technique. Interviews were carried out with expert and experienced contractors’ professionals who were proven in Sri Lankan construction industry to identify their experience and perception on use of project management tools/ techniques in cost monitoring and controlling in Sri Lankan construction industry. The study was concluded through the interviews of twenty nine respondents whilst limiting the scope to post contract construction companies as their contribution to the cost monitoring and controlling is excessive. According to the research findings; though there are numerous project management tools/ techniques available for post contract cost monitoring and controlling, Sri Lankan professionals are utilizing only a few of tools/ techniques such as Earned Value Analysis and Budget Monitoring. There are frequent confines for the applicability of these tools/ techniques followed by knowledge deficiencies, less commitment and unconstructive attitude of employees, and difficulties of obtaining data on time are momentous. Raising the awareness and using standardized formats/ procedures are the most effective and common corrective actions practiced by the current industry. Importance of maintaining a standardized practice, involvement of the established professional bodies and maintaining a database/ library on completed projects are the professional’s opinion for future improvement in this regard within Sri Lankan context.
