Question

I refer to the Rottnest Island Authority Annual Report 2016-17, and I ask:
(a) in relation to Service 2 “sea wall” on page 68, was the sea wall made structurally sound; and
(b) if yes to (a), what works or maintenance was undertaken and on what dates?

Answered on 6 December 2018

(a)   Yes.

(b)   The works involved:

        -   propping of the wall;

        -   grout column injections behind the wall to create a new mass retaining wall;

        -   removal of top soil behind the wall on Vincent Way and trimming of intersecting tree roots;

        -   installation of a tree root barrier system; and

        -   conservation works to the face of the wall including removal of limewash to enable underlying cement mortar repairs and replacement of stone voids, before the limewash was repaired to match the existing sea wall colour.

 The work commenced in November 2017 and concluded in June 2018.
