Abstract
The construction industry is one of the fastest
growing and most profitable in the world. The industry is
vital, especially in Qatar where infrastructure is growing.
In the construction industry in Qatar, design–bid–build
(DBB) is the most common project delivery technique;
nonetheless, it has several drawbacks. Through a thorough assessment of the literature, this study attempts to
investigate the DBB project delivery technique in the construction sector. A total of 10 studies met the inclusion
criteria. The findings demonstrated that in comparison
to DB, CM, CMAR and PPP project delivery methods, the
DBB project delivery technique has some advantages and
disadvantages. Project delivery techniques are crucial to
the construction sector, which is essential to the growth
of the national economy. The present study examines
the design–bid–build (DBB) methodology, which is a
traditional paradigm that presents ongoing difficulties in terms of contractor selection and project delivery
effectiveness. A thorough examination of the existing
studies was carried out using PRISMA guidelines. The
study found that there was a substantial knowledge gap,
as previous studies have mostly highlighted problems
without providing a systematic foundation for remedies.
The correct framework should be chosen based on factors
including cost, time and location. In Qatar, low-bid pro
jects that have well-defined objectives and well-defined
contractor pre-qualification might benefit greatly from
the application of the DBB project delivery approach.
A few of shortcomings of the research are the researcher’s prejudice, the incompleteness of the material gathered and the analysis of the findings. To replicate better findings, a comparable study can be undertaken in similar
geographic places in the future. Robust pre-qualification
procedures for contractors, improved designer–contrac
tor communication, incorporation of cutting-edge project
management systems and efficient risk management tech
niques were among the useful suggestions that surfaced.
The study emphasises how crucial it is to maximise the
DBB approach in the building sector. Subsequent research
should corroborate these suggestions, investigate the
incorporation of technology, evaluate the extended-term
efficacy of undertakings and promote interdisciplinary
cooperation. Through this activity, the construction indus
try may contribute to the sustainable growth and develop
ment of the industry by improving project results and the
overall efficiency of the DBB model.
