NB: Bold - exceedance
1Additional 3dB (A) facade correction was made to the Free-field measurements
*  No adjustment was made on the measured noise level, since corresponding baseline level ≥ measured noise level. The measured noise level was mainly dominated by local traffic noise and the construction noise generated from the Project was not noticeable at NSR according to the field study record.
** No Construction works was carried out during the reporting period
# No monitoring was undertaken due to bad weather
