Tracks
Te Ngahere are experienced in the installation of a variety of walking track types. Constructing a well-formed track involves carrying out each of the following tasks:
Benching
The correct benching of a walking track is a key requirement for long-term track resilience. Te Ngahere's benching service involves:
the
analysis of track routes prior to commencing construction within sensitive or
significant sites is considered to be
essential: - click here for Route-finding
and Mapping information
the
use of a "mini digger" to cut into slopes (where necessary), or to
add earth to depressions along a track route
a minimal environmental foot-print, due to the width of the digger being less than the specified track widths
i.e
it doesn't damage track edging, rubber tracks and a low profile also soften the
machine's impact on the environment
flexibility
with regard to accommodating changes that occur in track design and
layout as the project progresses.
Watertables
The identification of issues associated with watertable management, channelling and drainage are important considerations in regard to preventing washouts and scouring.
"Water tables" are installed with a 100mm deep x 200mm wide drainage channel dug on the uphill side of the track, with a culvert (usually 150mm diameter) directing the water under the track and into natural soakages or depressions.
To reduce the amount of run-off via the drainage channel a silt-trap is dug into the channel/ watertable at the entrance to all culverts.
Metalling
Te Ngahere's metalling service includes:
the use of a well-graded, specially sourced aggregate, laid over a GAP 40 basecourse,
due to the firmness to which
it compacts.
the transportation (as required) of all metal via a Honda power-carrier which carries up to
0.2 m³ of metal, which is
loaded directly off the back of a tipper truck.
avoiding the stockpiling of more than 4 m³ of metal at a reserve entrance.
the use of a plate compactor to achieve a uniform surface free from loose chip.

Walking
track, Church Bay, Waiheke Island
Te Ngahere is currently
contracted through Auckland Council to upgrade 600
metres of tracks at Church Bay on Waiheke Island, involving
relocation of a team to the island, hand excavation of
a registered archaeological area, and protection of 100
year
old pohutukawa
trees. More. |
