The Contractor shall nominate the proposed sand source and provide particle size distribution data upon request. The Contractor shall mechanically spread and incorporate topdressing material in incremental passes and shall not apply the full depth in a single pass. The material shall be distributed evenly across the nominated playing surface to achieve an average finished topdressing depth of 10 mm. Following each application pass, drag matting, brushing, levelling or other approved finishing methods shall be undertaken to ensure even distribution and incorporation of the material. Any low areas, depressions, hollows, birdbaths, surface undulations or other irregularities identified during the works shall be filled and levelled as required using additional topdressing material. Hand placement and finishing shall be undertaken where necessary to achieve a smooth, uniform playing surface and eliminate localised variations in surface level. Upon completion, the surface shall be free of ridges, windrows, excessive accumulations of material and abrupt level changes, and shall maintain positive surface drainage suitable for sports field use. The Contractor is responsible for undertaking works in accordance with industry best practice, relevant workplace health and safety legislation, and manufacturer recommendations for all equipment used. Works must be completed in a manner that minimises disruption to sporting clubs and facility users while maintaining safe access to surrounding areas.

Upon completion, the Contractor shall provide confirmation of: • Areas treated. • Aeration and coring methodology utilised. • Quantity and specification of top dressing material applied. • Any defects, irrigation faults or field condition issues identified during the works. The completed surface must provide an even, safe and high-quality playing area suitable for community and competitive sporting use.
