Even by 1980 it was observed that software for
construction management comprised many independent packages
with different programming languages and hardware. By and
large, not only were these packages stand alone systems but
they were also not suitable for their individual functions.
Not only do construction projects increase in complexity
but competition and volatile markets also generate pressures
for better management and that requires integrated and
effective systems.
The hypothesis of this research has been that computer
technology and systems concepts can be used to develop the
necessary tools that will make integration possible and
effective. To that end, the following research has been
undertaken:
* an investigation of the causes of the lack of
integration,
*a survey of the operations of the management
functions,
* the specification, development and testing of a
computer-based system called PLUS VAL to demonstrate
the viability of integration,
* an assessment of PLUS VAL.
Causes of lack of integration revealed include:
* segregated education, training and working of
functional groups,
* development of software by people without the
relevant expertise,
* inadequate research and failure to apply research
findings due to the structure of the construction
industry.
A survey of the operations showed:
* the various methods of carrying them out,
* the flow of data among them,
* their interdependencies.
The major features of PLUS VAL are:
* it assists valuations, purchasing management
and cost control,
* it can be linked to estimating, planninq and
accounting,
* it allows quick access to contract information.
Its assessment which involved demonstrating it to and
interviewing potential users, and comparisons with similar
packages commercially available showed that:
* It provides all the facilities that the users wanted
* It covers all the methods of operations of companies
contacted -
* It is more comprehensive than those surveyed -
* Integration is possible and provides such benefits
as:
. reduced costs of data capture,
. better use of computer storage,
. reduced turn around times of data processing,
increased data consistency.
The results of the research show that the application
of computer technology and systems concepts can produce
effective integrated systems which not only assists
contractors in carrying out their obligations but also
provide reliable information for decision-making.
