Description of Process In this process, slurry of water, organic mulch, sprigs or stolons (chopped grass, such as couch, kikuyu, etc), fertiliser and soil conditioners and binders are homogeneously mixed in a purpose-built, truck-mounted tank. The slurry is sprayed onto the site from the truck via a directional monitor and can be pumped through extension hoses for up to 200 metres if necessary. The slurry bonds to the soil surface providing an ideal medium for germination and even distribution of sprigs and fertiliser.

Extent of Work: The work included in this contract is as follows: HydroSprigging of Recreational Turf Areas such as golf greens and fairways, etc.

Contractor's Qualifications: Each tenderer shall submit documentary evidence of his proven ability to carry out this type of work. Such evidence shall include a list of similar projects satisfactorily completed together with a statement of the qualifications and/or experience of the personnel to be employed on the works, quality assurance procedures and suitability of equipment to be used.

Site Preparation Where possible, prior to topsoiling, the areas should be deep-ripped. After topsoiling, all areas to be sown shall be scarified to provide a reasonably firm but friable bed, free of weed or other plant growth, large stones and debris, and the whole area fallowed and left ready for HydroSprigging.

Application Rates: The Contractor shall apply the following to areas be treated: a) Stolons/sprigs(Sowing rate as per supplier’s recommendation) The rate will vary according to the season, soil condition and client requirements. Typical sowing rates are 10 - 40 cubic metres per Ha. b) Approved Fertiliser (Application rate as per supplier’s recommendation) Selection of fertiliser will depend on soil analysis results and client requirements. Typical application rates are 250 - 500 Kg per Ha. c) Mulch Defibrated pinus radiata fibre or cellulose mulch (recycled paper). Typical application rates are 1500 - 2000 Kg per Ha (dry weight) d) Binder(Organic Tackifier) Application Rate is dependent on slope and erosion control requirements. Typical application rates are 60 - 80 Kg per Ha.

Operation: Stolons/sprigs, fertiliser and selected mulch, water and binder shall be thoroughly mixed together with a suitably coloured marker dye to provide a slurry and then applied under pressure on to the area to be treated, by means of Hydromulching equipment specifically designed for this purpose and by operators trained in the use of this equipment. NB: Stolons must be washed and chopped with maximum length of 50mm. The constantly agitated slurry shall be applied on a calm day, operating on a front so that the mixture is evenly distributed over the area at the specified rate. Complete each front before commencing the next. Care must be taken to minimise over-spray on to adjacent garden beds, kerbs or other fixtures.

After Care Maintenance Adequate watering must be provided to ensure successful germination in the critical first weeks and to ensure a vigorous healthy sward of grass is achieved. A management plan shall be prepared (as per seasonal requirements) for watering, post-fertilising weed eradication and mowing.
