1. Construction & Renovation of Amenity Turf

2. Planning Be Organized 1.Closure 2.Work with growing seasons 3.Organize materials 4.Notify relevant parties of intended work

3. Dethatching Take the opportunity 1.Aggressive 2.Deep 3.Multiple directions 4.Remove Deadbrie off site

5. Aeration Opportunity to be aggressive 1.Increases soil oxygen levels 2.Reduces compaction/ keeps profile open 3.Avenue for roots & water to infiltrate 4.Opportunity for fertilizer to work into profile 5.Remove at least 10% of surface each year 6.Alternate depths

11. Fertilizing Opportunity to make amendments/ push recovery 1.Soil testing 2.Applications based on soil test results 3.Predominate NPK applications to push recovery 4.P applications 5.Soil amendments

13. Topdressing Make most of closure 1. Correct levels 2. Improve surface smoothness 3. Dilutes thatch 4. Improves drainage 5. Top-dress using same material as profile make up

15. Turf Regeneration Choose most suitable method 1.Stolonising 2.Re-turfing 3.Use existing area as a nursery 4.Seeding

16. Why Construct or reconstruct? 1.Upgrade surface 2.Old surface reach used by date 3.Undesirable surface levels 4.Restricted drainage 5.Unsuitable grass species 6.Irrigation upgrade

17. Goals for reconstructing? Be realistic 1.Consistency 2.Profile that supports the grow healthy turf 3.Can deal with heavy rainfall 4.Handle usage 5.Can be maintained under a reasonable budget

18. Construction Considerations Consider all options 1. Identifying a suitable grass species 2. Establishing an ideal growing medium 3. Designing a suitable drainage system 4. Choosing & designing an appropriate irrigation system 5. USGA OR Californian method

19. Site Evaluation Cut & fill 1.Access 2.Water 3.Environmental issues 4.Drainage discharge 5.Profile inspection – current soil ok? 6.Base Considerations

20. Profile Considerations Growing medium most important 1. USGA or Pure Sand – most common 2. All surfaces can be constructed similar 3. Physical or nutrition amendments 4. Sand stabilizers 5. Physically & Biologically well balanced

21. Designing the Drainage System Invest in good drainage 1.Establish a drainage rate 2.A design rate was established of 25mm/hour 3.Design – work with contours 4.Pipe Sizing 5.Budget

22. Hooghoudt’s Formula 1.Hooghoudt’s formula takes into consideration, the rootzone depth, rootzone infiltratation rate, and required drainage rate 2.Hooghoudt’s formula is the best formula to determine the drainage pipe spacing

23. Hooghoudt’s formula

24. Irrigation Check water source 1. Use experience designer 2. Quality materials 3. User friendly design 4. Abundance of water points 5. Separate trenching for irrigation 6. Head to head coverage

26. Choosing a Suitable Grass Investigate & be realistic 1. Assess usage requirements 2. Evaluate budget & maintenance budget availability 3. Ensure future availability of species 4. Assess objectives – presentation/wear 5. Conduct trials 6. Site visits/access local grasses in use

27. Species Considerations Know your grass 1.Bermuda Grass 2.Zoysia grass 3.Seashore Paspalum 4.Carpet Grass

28. Stolonising Generally a better surface long term 1. Cheaper 2. Easier to import grass 3. Better root system in first year 4. Faster opening 5. Easier to reduce height (less scalping)

29. Stolonising High inputs a must 1. Rate 1:5 – 1:10 2. Ensure good soil contact 3. Top-dress in 4. Keep damp 5. Aggressive fertilizer program

32. Sodding Instantaneous Grass Cover 1. Instant 2. Prevents erosion 3. More expensive 4. Instant thatch layer

34. Grow In Success only as good as grow in 1. Be prepared 2. Have good understanding for species in use 3. High inputs will be required 4. Important to give grass what it wants

35. Machine Considerations Be realistic 1. Audit on current machine list & their capabilities 2. Ensure you have all the machines requires 3. May require an increased budget 4. Machine Sharing

36. Dealing with Contractors Work Closely 1. Be clear with standards 2. Understand what drives the Contractor 3. Effective Communication

37. Dealing with Expectations Communication is key 1. Clear communication 2. Good understanding for expectations 3. Assess maintenance constraints 4. Budget Expectations

47. Profile Kept even as possible 1. Growing medium laid in two 125mm layers 2. Bottom layer unamended, top layer amended 3. Consolidated by both machinery & Irrigation 4. Final leveled mirrored the sub-base falls
