**4. Conclusion**

This chapter featured the systems utilised in measuring productivity in the construction industry. There are three noteworthy techniques that are possible for measuring construction skills productivity. The first identifies visual recording strategy that includes the use of consistent record of the labourer execution output on sites. The second is the physical recording procedure which includes

an immediate surveillance system that incorporates a qualified onlooker really watching the site for the full length of the working day; the eyewitness or observer concentration is on a group of skilled workers who record the time spent on direct work. On enormous sites, more than one onlooker might be expected to productively watch the task of work utilising work study, method study or work measurement. The third measuring system is the utilisation of surveys and interviews which include data assembling through a meeting from supervisors and workers working in the construction industry. Finally, the chapter concluded that infrastructure productivity can be improved through effective supervision, material management and supply chain management, project front-end planning (loading) and work face planning, training and certification of workforce and labour management and relations. The above different strategies featured and talked about with illustrations are utilised in the measurement of infrastructure skills productivity.
