In the paper of Chwała (2021), a bug in the used numerical implementation was found.It concerns one of the covariance matrix coefficients that was incorrectly updated during the simulation process.As a consequence for some fluctuation scales, different bearing capacity standard deviations are obtained;however,the bug had a very limited impact on the found optimal borehole placement.Therefore,the conclusions given in the paper are still valid.The author has re-analyzed all numerical examples presented in the paper and will provide the results on an individual request.In Fig.1, corrected Figs.5, 9, 7 and 11 in the original paper are shown.
