RISK PERFORMANCE INDEXES AND MEASUREMENT SYSTEMS FOR MEGA CONSTRUCTION PROJECTS

Abstract

In recent years, interest in and studies on urban regeneration projects have increased. New urban regeneration projects, i.e., redevelopment projects, are being used to help solve the social and economic problems caused by antiquated buildings and degraded infrastructure. However, such projects can offer no performance guarantees because they have various and complex stakeholders and their huge scale exposes them to many risks. We propose a risk performance index to improve the efficiency of general performance measurement for mega projects by extending the existing cost/schedule‐based performance measurement system to include the risks of such mega projects. The risk performance index method proposed in this study is similar to the conventional EVMS and makes it possible to perform a three‐dimensional integrated performance measurement of cost/schedule/risk through 18 indexes and variables. Santrauka Pastaraisiais metais miestu atnaujinimo projektai vis dažniau atsiduria demesio centre ir yra tyrinejami. Nauji miestu atnaujinimo projektai, t. y. pertvarkymo projektai, naudojami sprendžiant socialines ir ekonomines problemas, kylančias del pasenusiu pastatu ir yrančios infrastruktūros. Tačiau tokie projektai nežada jokiu efektyvumo garantiju, nes juose dalyvauja ivairiausios ir sudetingos interesu grupes, o del stambaus masto jiems gresia daugybe rizikos rūšiu. Siūlomas efektyvaus rizikos valdymo indeksas, padedantis geriau ivertinti bendra efektyvuma stambiuose projektuose, nes esama sanaudomis ir terminais pagrista efektyvumo vertinimo sistema papildoma rizikos rūšimis, būdingomis tokiems stambiems projektams. Šiame tyrime siūlomas efektyvaus rizikos valdymo indekso metodas yra panašus i iprastas atliktu darbu vertinimo sistemas (EVMS). Jis leidžia atlikti trimati integruota efektyvaus sanaudu, terminu ir rizikos valdymo vertinima pagal 18 indeksu ir kintamuju.
