"Football Grass Field" Project of WYK

Need of professional advice on:

1) Whether an artificial grass field is a good alternative to the existing natural grass field? In medium term? In long term?

2) How many different types of artificial grass field WYK should consider? How many qualified vendors there are in the market?

3) What are the true costs of the artificial grass field, with ongoing maintenance included?

4) What are some other related construction costs, such as foundation, draining, or even lighting?

If you happen to know such technical expertise, please give Wah Yan a lead or referral and feel free to contact Gordon.
