Productivity planning and control on construction projects

Abstract

In this paper, traditional as well as contemporary approaches to productivity planning and control are analyzed and potential improvements are suggested. A new approach is proposed. It is based on: applying separate measures for work and for labor, defining organizational levels for application (work flow and crew level) and introducing space-based control points. Having in mind the importance of planning for productivity, a separate measure for evaluating the quality of plans is proposed. That measure is based on comparing the calculated and planned productivity. The first originates from the bid and serves as benchmark for control and the second originates from the organization of works on site and planned crew capacities. A case study showed that the application of the proposed approach enables more efficient productivity control, rapid achievement of planned crew and overall performance, more precise corrective measures, faster system response and enhancing productivity on construction projects.

U radu su analizirani klasični i savremeni pristupi u planiranju i kontroli produktivnosti i prikazana moguća poboljšanja. Predložen je novi pristup koji se zasniva na formiranju posebnih ocena za produktivnost radne snage i produktivnost rada, definisanju ključnih organizacionih nivoa (tokovi rada i radne ekipe) za kontrolu produktivnosti i uvođenju kontrolnih tačaka zasnovanih na prostornom principu. S obzirom na značaj planiranja za nivo ostvarene produktivnosti predlaže se uvođenje posebne ocene za proveru kvaliteta planova, zasnovane na poređenju kalkulisane i planirane produktivnosti. Kalkulisana produktivnost proističe iz prihvaćene ponude izvođača i predstavlja etalon za kontrolu, a planirana produktivnost proističe iz usvojene organizacije rada i dinamičkog plana. Studija slučaja je pokazala da se primenom predloženog pristupa može poboljšati efikasnost kontrole produktivnosti, brzo dostići planirane performanse proizvodnje i radnih ekipa, fokusirano primeniti korektivne mere, povećati brzina 'odziva' sistema i podići produktivnost na građevinskim projektima.
