Total quantity or scope of tender
The site is 14ha.
The planned interventions are:
Standard Peat Dam or Coir logs: 2680m gully (268 dams)
Blocking of small gullies in a patchwork/dendritic area, on average 2-3m wide, dams installed roughly every 10m. Peat dams are preferred due to a greater water holding ability and no need for materials. However if machinery access is not possible, it may be best to install coir or sheep wool logs/rolls. Please estimate what you think would be doable in your quote, based on your experience and site visit.
Standard/ low Peat Dam: 450m gully (45 dams)
Blocking medium gullies, on average 5m wide. Dams to be installed roughly every 10m.
Hagg Reprofiling: 300m
Reprofiling peat haggs between 50cm and 1m.
Contour Bunding: 2960m (3850 including cross-bunds)
Contour bunds both in dendritic area, and flat modified bog surface.
Bund height with turf will be 400mm. Bund width will be 1m. Average 6m cross-bund every 20m. Covered with vegetation or Jute if necessary.
Jute: 990
Potential length of intervention requiring Jute (rough estimate) where there is little vegetation. Use of existing vegetation is preferred, and this can be discussed on site with the chosen contractor.
