FACTORS AFFECTING CONSTRUCTION LABOR HEALTH, PRODUCTIVITY FOR CONSTRUCTION OF PRE-STRESSED CONCRETE BRIDGES

Abstract
Purpose – Construction labor productivity in bridge is of great interest to practitioners
and researchers because it affects project cost and time overrun. This paper evaluates and
ranks the importance, frequency and severity of project delay factors that affect the
construction labor productivity for construction of Pre-stressed concrete bridges.
Design/erection / methodology
A total of 50 respondents consisting of owners contractors, and consulting participated in
this study. The respondents were asked to indicate how important each item of a list of
many bridges project related factors was to construction labor productivity for
construction of Pre-stressed concrete bridges. The data were then subjected to the
calculation of important indices which enabled the factors to be ranked.
Findings
The eleven most important factors identified by them were: design factor , equipment
factor , execution and construction factor , external factor , financial factor , heathy and
safety factor , labor factor , supervision factor , material factor , organization factor and
other project factor .
Originality/value
From this study could be used by the project managers to take this factor at an early
stage, hence minimizing the time, cost and maximizing factors that affect the construction
labour productivity for construction of Pre-stressed concrete bridges.
