Mt Wellington Seawall Renewal
Tamaki Estuary, Auckland
|Services:||Detailed Design Reveiw, Construction Documentation, Tender Stage Services, Construction Stage Services|
|Scope:||440m Seawall Renewal and Repair|
In April 2014, Auckland Council Coastal Management Services completed a
coastal structure condition assessment for a 6km section of the Tamaki Estuary
within the Maungakiekie –Tāmaki Local Board Area at the request of Local Sports
Parks (Parks, Sport and Recreation Department).
The intent of the assessment was to assist Local Sports Parks with future reporting
to the Maungakiekie-Tāmaki Local Board regarding ongoing management
options and related regulatory requirements.
Urban Solutions were engaged by the Maungakiekie – Tamaki Local Board to
repair the 440m section of sea wall which the report identified as having a “fair
to poor” condition rating. The coastal edge is located adjacent to multiple sports
fields and the non-engineered edge was prone to erosion and over-topping. The
team provided project management services including preparation of tender
documentation, through physical works, construction supervision and contract
management. This constructed engineered seawall will complement the new
Tamaki Path and allow for safer recreation at the coastal edge. The wall has been
tested during the January storm event and performed well.
