ABSTRACT: This paper aims at detecting the causes of delay in
the “design and build model” of motorable bridge construction under the Bridge
Project, Department of Roads, Nepal. The research is based on an intensive
literature review, primary data, secondary data, and interviews. The survey
which was carried out with the help of questionnaires was used to assess the
perceptions of the respondents involved in the construction of the “design and
build model” of the bridge project. The questionnaire was divided into three
parts and the main part focused on the causes of delay in “design and build
model” in the implementation of such projects. A total of 56 different causes
for delay of bridge construction were identified through the literature review
and a pilot survey of three groups of respondents who were involved in the
construction of such bridges (see literature review of this paper). The eight
most important causes, among 56, identified by the study are: 1) Lack of
stakeholder analysis 2) Poor portfolio management 3) Lack of inadequate
pre-execution planning and improper time management 4) Lack of site management
5) Inadequate budget allocation and delay in payment 6) Lack of provision of
reward and penalty, 7) Lack of detail survey, improper soil exploration and
preparing report without depth study and 8) contractor’s excessive workload.
The cost, quality, and schedule of bridge construction projects can be
maintained once the problem of unnecessary delay is resolved and the competency
of the construction industry in Nepal will improve.
