This is a list of 30 risks that impact Construction projects. This is not an exhaustive list but is a good starting point for your
risk register
. It doesn't include risks associated with particular areas of construction for example right of way risks or environmental risks.
List of 30 Construction risks
-
Aerially deposited lead (ADL) contamination from use of leaded petrol/gasoline is discovered late.
-
Changes require additional
resources
or different
resources
than predicted causing resourcing conflicts/delays.
-
Choice of plant or cranes is found to be unsuitable during construction.
-
Construction staging (storage) areas are not large enough.
-
Contractual disputes between client and contractor or contractor and subcontractor.
-
Deep excavations needed in bad ground leading to risk of collapse, falling materials etc.
-
Designs for temporary excavation and shoring system are not correct
-
Errors in
method statement
s lead to delays.
-
Errors in the quantity surveys.
-
Failure to achieve the quality required and/or functional requirements of the build.
-
False work design is not sufficient for example it is not complete or accurate.
-
Fire risk from arson, construction technique or removal waste.
-
Liquidated and ascertained damages are insufficient to cover costs if project finished late.
-
Multiple
Change requests
are needed due to unexpected site conditions

-
New or innovative technology is used in the construction which may lead to unfrozen complications and delays.
-
Not enough time allowed for getting Permits
-
Overhead power lines not identified and found obstruct construction work
-
Poor inaccurate or over optimistic contract time estimates
-
Road closures or partial street closures are delayed because of inadequate coordination and planning. For example not informing the community or not given sufficient notice of works.
-
Sensitive or protected habitats delay demolition or construction for example Bat habitat.
-
Special parts or equipment has to be manufactured to provide the utilities leading to longer lead times and delays to start of construction.
-
Subcontractor delay or resourcing problem.
-
Subcontractor in has financial issues/cash flow issues.
-
Theft from the site by workers or break-ins caused by insufficient security.
-
Unexpected buried man-made objects or hazardous waste is found on site.
-
Unexpected paleontology or archaeological artefacts found.
-
Unidentified utilities for example gas pipes are found on site.
-
Water table is found to be higher than expected or changes resulting in the need for dewatering.
-
Work or design takes longer than expected leading to temporary construction easements expiring.
-
Working at height and management of associated hazards leads to delays and increased cost.
