DEKACON was engaged to undertake road maintenance and upgrade works to a 3.3km section of road within the Boorabee Gurrheel Flora Reserve, Woodenbong NSW.
Pre-works included;
- Access upgrade works to a 1.1km section of Tenterfield Shire Council Road, which passed through a privately owned cattle property to the National Park entry.
- Clearing of existing drainage lines to open water passage from the road alignment
- Importation and placement of quarry materials to suitably reinforce the access for truck movements.
The project consisted of working to a comprehensive scope of works supplied by the NPWS Project Officer to identify how existing drainage pathways were performing. Works also included the removal of culverts which weren’t performing, (or were in locations that restricted water run-off), and the construction of new pits with surge grates and headwalls to bolster the remaining culverts to handle surface water runoff and drainage networks. DEKACON also constructed and reshaped rollovers and mitre drains to new design standards that we’re originally designed to meet the capacities of water runoff to slope gradients and measured catchment models. DEKACON managed importation of the quarry products supplied by BCQ Quarry to ensure materials, quantities and stockpiling met the supply contract between NPWS and BCQ Quarries. After road material placement and shaping, DEKACON applied a “POLYCHOR Omega” product to enhance road surface wearing in conjunction with FIVE ELEMENTS Pty Ltd.
Post works included:
- Installation of guideposts to delineate culvert locations
- Removal of sediment controls
