Work on the Robinson Road Boat Ramp in Whitianga, in order to improve it and take pressure off the boat ramp by the
wharf, has begun.
The contract has been awarded to Schick Construction and the improvements will include reshaping the boat ramp and
installing a floating pontoon. The work is expected to take 8-10 weeks but is weather-dependent.
"We expect the disruption to the existing ramp facility to be kept to a minimum; however, the site for the new facility
will be fenced off along with an adjacent site area on the reserve land," says Andrew Scobie, our Council's project
manager.
"Where possible, the existing ramp and/or adjacent beach will still be able to be used for launching during most of the
construction period; however, there will be times of restricted access and parking," says Mr Scobie.
"To allow the construction to commence we have had to relocate some stored dinghies to adjacent parking area. Please see
the site staff for key to relocate your dinghy," says Mr Scobie.
The plan looks at ways to help alleviate congestion at the Whitianga Wharf Boat Ramp, which is a busy area with
tourists, ferry passengers and children.
"There has been many investigations historically and proposals into possible sites for the development of a single
'destination boat ramp', to help cater to the growing number of recreational and commercial fishers and boaties," says
Allan Tiplady, our Council's District Manager - North.
The first task is to set up the site, including barriers, signage and temporary fencing to restrict access to work areas
for the safety of pedestrians.
The work will be carried out during low tides. Excavators will be used to build a rock causeway to access the deepest
point.
Once our contractors reach the end of the ramp area we will excavate the seabed to form the new boat ramp approach. The
GPS excavators will shape and form the new ramp as it works back to a level above the high water mark.
The rock causeway will be progressively removed and used to form the new ramp shape and upper harbour revetment. Silt
will be managed with silt fences and a tepidity curtain and monitored throughout the process.
A large crawler-type crane will be put on site to install sheet piling and sand bags to form a coffer dam which will be
emptied of water for the ramp construction.
Once dry enough the construction of the ramp can start with concrete footings and precast panels to form the retaining
wall between the old and new ramp.Then final shaping and trimming of the ramp will be done before the boxing,
reinforcing and concrete is poured for the new ramp surface.
Then final shaping and trimming of the ramp will be done before the boxing, reinforcing and concrete is poured for the
new ramp surface.
Once the new ramp has cured, the timber fencing and piles can be driven for the floating pontoon before the sheet piling
is removed.
The new floating pontoon will be floated into position. Finally the reshaped road kerb can be poured and the new asphalt
vehicle staging area formed and laid.
The site will be decommissioned and equipment demobilised before cleaning up the site.
Whangapoua Boat Ramp upgrade
Design consultation and consenting for work to rebuild the two-lane concrete boat ramp at Whangapoua and install a
floating pontoon is happening this financial year.
Stage one re-construction of the concrete boat ramp is planned to start during 2019/2020, while stage two of the boat
ramp upgrade installation of the pontoons is scheduled for 2022/2023.
The existing boat ramp is in a deteriorating condition with cracks in the concrete at the end of the ramp and in between
the ramps. is cracked and breaking.
The existing boat ramps were poured at two different levels, which has caused some safety concerns for boat ramp users.
The proposed concrete boat ramp will eliminate these issues and the addition of a pontoon will make the boat ramp more
user-friendly for boaties.
