Abstract
Climate change affects the ecosystems as it creates desertification and serious flooding, and thus, increases the risks associated with embarking on construction project planning. The study assessed the effects of climate change at the first three
stages of "the project management cycle" otherwise regarded as project conception
planning, project design planning and construction planning. A structured
questionnaire was used to obtain responses from eighty-eight (88) construction
practitioners representing 73% response rate. Mean and repeated measure ANOV A
test was used to establish the average scores and to explore significance differences
among variables respectively. Frequent rainfall and extreme air temperatures delaying
site preparation activities is the most significant effect of climate change on project
conception planning, followed by high insurance costs on projects within flood prone
areas. Severe weather events,45 which influence the selection and specification of
construction materials, were considered as the greatest impact on project design
planning. Too much rain which interfere with construction schedule and mixing of
concrete causing newly laid concrete to be destroyed and, high wind which poses
danger to lifellimbs at the construction sites on building requiring the use of scaffold
were ranked very significant effects of climate change on project construction
planning. Extreme weather events which influence the structure of site organization
plan, and extremely low temperature interference with construction work were
outranked in project conception planning and construction planning respectively. The
study has provided construction professionals and project managers with useful
information and considerations on the effects of climate change on construction
project planning.
