Coping with delays is an ever-present challenge for construction projects
throughout the world, and both practitioners and researchers have focused their
attention on ways to prevent them or to mitigate their effects. Civil engineering
projects in Libya, too, especially projects involving road construction,
constantly face construction delays. This study proposes a conceptual model of
delay factors and provides an analysis of the level of impact of identified delay
categories on the completion of the road construction projects. Data for the
study were obtained from 256 valid responses to questionnaires and analysed
using the Statistical Package for Social Sciences (SPSS) software. Thirty-nine
delay causes that influence delay in road projects were identified and classified
into 8 core groups of factors in the final conceptual model. The five most
significant factors affecting the completion of the project are: (US1) Delays in
the conversion and transfer of utility services by the competent authorities (such
as power lines, water, etc.) (mean = 4.03); (OW1) Difficulty in Budget
availability for the project (mean = 4.02); (PR1) Original contract duration is
too short (mean = 3.96); (OW4) Delay in progress payments by the owner
(mean = 3.96); (US4) Effects of subsurface (underground) conditions (mean =
3.89). Since the contractor has the most significant impact on the delay in road
projects, control of the delay is influenced by the group of factors pertaining to
the contractor. Parties involved in government construction projects can benefit
from the findings of the study, which can help them find suitable solutions to
resolve delays.
