John Laing Infrastructure Fund Limited said its investment adviser had contingency plans in place for the collapse of Carillion.
And JLIF said it expected minimal service disruption and minimal additional cost to its nine operational projects where Carillion was the facilities management provider.
JLIF said the value of these projects was approximately 8.5% of the total portfolio value and approximately 9.6% of the net asset value using 30 June 2017 valuations and acquisitions since then at cost.
It said: 'The investment adviser's asset management team have been aware of the issues affecting Carillion and have had contingency plans in place for some time.
'These have involved discussions with a number of potential replacement providers and the investment adviser is in the process of implementing these contingency plans and seeking to appoint alternative FM providers on all of the 9 projects to replace Carillion.
'At this stage the Investment Adviser expects that this can be achieved with minimal service disruption and minimal additional cost. '
JLIF said it had no projects currently in construction where Carillion were the contractors.
JLIF said it owned one project where Carillion was still liable for any construction defects found on the project, with the construction period having completed over 10 years ago.
It said a recently completed routine defects survey had not highlighted any significant areas of concern.
It said the investment adviser believes that the compulsory liquidation of Carillion should have no material impact on the company.
It said the company will continue to manage the situation as it develops and provide further updates as appropriate.
