The CRL also requires 850m of modifications within the NAL.<\/p>\n<p>Matthew represented the project through expert statement of evidence at public hearings and undertook detailed ground-borne noise and vibration modelling and assessments during the definition design and reference design phases. To refine ground-borne noise and vibration predictions at some key receivers, ground attenuation and building coupling loss was measured utilising existing boreholes and drill rig to excite the ground. Throughout the project Matthew has worked closely with Aurecon and Auckland Transport.[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_column_text css=&#8221;.vc_custom_1597200418308{margin-right: 50px !important;}&#8221;]This project also involved the design of detailed rail vibration mitigation measures to isolate the vibration of the new rail line from existing and new commercial developments, notably the Commercial Bay Development.\u00a0 To calculate the regenerated noise levels and vibration potentially affecting the proposed Commercial Bay Development, a detailed FEA model was created of the proposed development.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/2&#8243;][vc_column_text css=&#8221;.vc_custom_1597200494972{background-color: #f5f5f5 !important;}&#8221;]\n<table width=\"643\">\n<tbody>\n<tr>\n<td width=\"189\">Client organisation:<\/td>\n<td width=\"454\">Aurecon and Auckland Transport<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_column_text css=&#8221;.vc_custom_1597200433156{background-color: #f5f5f5 !important;}&#8221;]\n<table width=\"643\">\n<tbody>\n<tr>\n<td width=\"189\">Value of work constructed as a result of the commission:<\/td>\n<td width=\"454\">NZ$ 2.5B<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n[\/vc_column_text][\/vc_column][\/vc_row]\n","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_empty_space height=&#8221;10px&#8221;][vc_column_text text_align=&#8221;center&#8221;
