Wanneroo City Council accepted a quote from Western Power on December 10 for the utility to install the lights, noting it exceeded the budgeted cost by $158,550.
The City will source the funds from savings from completed capital works projects in its mid-year budget review.
Councillors also noted Wanneroo would continue to liaise with Main Roads WA to get a funding injection to cover the extra costs incurred during the black spot upgrade at the intersection.
The report said the project had an approved budget of $1 million but costs increased during construction.
‘Actual costs incurred in carrying out the works on the project overall will exceed the approved budget due to scope of works changes experienced in relation to the extent of hard rock excavation encountered, additional underground service relocations (i.e. gas and power), associated traffic management,’ it said.
‘The additional street lighting to be located immediately adjacent to the two recently opened bypass lanes will add a further $158,550 to the project cost. The additional street lighting needs to be installed in order to comply with the State Black Spot conditions of funding.’
