Ali Civil was engaged by the Shoalhaven City Council to design and construct the replacement of the old, dilapidated mangrove boardwalk at the Jervis Bay Maritime Lady Denman complex. The project involves removing the existing timber boardwalk and replacing it with helix screw piles with FRP piles, rails, kick rail, deck and handrails. The project also involves replacing the marine interpretative signage and construction of a new concrete footpath.
