Forvie NNR, is a nature reserve located at Collieston, nr Newburgh on the North East coastline. We have had 2 projects here, and both have involved the removal of boardwalk that are coming to the end of their working life. The boardwalk has been replaced by gravel and stone paths and also 2 wooden bridges. To avoid trampling the fragile sand dunes, all the material was flown in by helicopter, and the old boardwalk was bundled up, and flown out on the reverse trip. The work was done by hand, with the gravel being carefully graded and compacted over a geotextile membrane. STATISTICS:- YEAR 2005 gravel path.. 220m pitching ..9m revettment..40m landscaping ...400 sq m helicopter lifts 160 YEAR 2007 gravel path.. 130m pitching ..20m revettment..30m landscaping ...140 sq m helicopter lifts.. 90 bridge boardwalk ...15m |

Still on the east coast, but further south, finds the dramatic cliffs and beaches of St Cyrus NNR, about 6 miles north of Montrose. This was a small, but tricky project involving the construction of a new drainage regime, to divert drain water from the cliff top car park, away to the neighbouring cliff. Before the project, the car park drain was outflowing onto the ground directly above the path. This had resulted in the erosion of the path, and also the path edge was becoming dangerous. By constructing and installing new brick and mortar manholes/drainage traps, and culvert pipes, the drain water was diverted away from the path, and the outflow was reinforced with a gabbion mattress. The path edge was also reinforced with gabbion mattresses and block stone revettment, and the path reinstated. The stone filled gabbions were then covered by the spoil from the excavations, and landscaped over.

Cartland Craig is part of the Clyde Valley National Nature Reserve, and is found on the outskirts of Lanark, overlooking the Cartland Bridge, a dramatic Telford designed bridge. We were contracted to reprofile and resurface parts of the pathline that were soft and potentially dangerous. We also installed wooden steps and anchor bars and installed a natural viewpoint area. Although this was reasonably straightforward project, the problems lay in having difficult access to the site, so all material was imported to the site by use of our tracked Honda Power Carrier.
