Abstract
The construction industry in Egypt has a reputation for failing to
meet budget and delivery schedules. The glib explanation for this is
that the industry has serious ”productivity problems”.
Productivity planning and improvement must be preceded by
productivity measurements and evaluation. An understanding and
quantification of the factors affecting labor productivity would
enable contractors to better estimate, plan, schedule and manage
construction projects.
Since almost all the data used in estimating and controlling
construction projects are empirical, the use of estimating means and
database can contribute a great deal of consistency, accuracy and
credibility. Most construction projects (especially residential
building construction) occur in significant numbers.
The main objectives of this study were three-folded. The first
was to study and record labor productivity work in Egypt. This is
done on certain type of labors such as concrete pouring labors. The
important factors affecting the process were taken into
consideration. Successive measurements, analysis and evaluation
of mean values of the productivity were performed. Analyses of
lost time for concrete pouring were carried out. The sources of lost
time in construction sites which cause low productivity, delay of
schedule and plan modifications were also pointed out.
The second objective of this study was to develop a computer
model that can simulate concrete pouring operations under
different conditions. The model can be used as a template and
modified according to the particular environment at site to improve
work productivity.
The third objective was to develop a relational database
system for both cost control and labor productivity control. The
conceptual design phase is done, and the relational database
application was developed using a powerful, Relational Database
Management System. The developed program is easy to use and
can be used at construction sites. The database program permits the
site manager to review his progress and control it.
