Dunedin City Council water and waste services asset strategy team leader Tom Osborn said Opus had the contract for the design and construction management of the refurbishment. The initial survey work had been completed.
During the next two weeks, bush and scrub would be cleared at the base of the existing embankment to enable detailed survey and design work.
Tracks around the embankment would be closed during this time and there would be noise and disturbance associated with scrub clearance between 8am and 5pm, Mondays to Fridays.
Mr Osborn said Opus would conduct detailed design work on the embankment buttress during the remainder of May, and in June a review of the design would be carried out by an independent qualified structures expert, an archaeological authority and a consenting authority.
Tenders for the works would be sought and awarded during July and August. Details such as the extent and duration of the track closures and site access requirements would be determined in conjunction with the successful contractor, he said.
Construction of the embankment buttress would begin in October and was expected to take about 12 months to complete. Once the work was completed, the area would be replanted, he said.
