According to the Tropical's proposed alternative tree support system, this tree support system is not as equivalent as in Tender Document. They provide only above ground tree staking, which is not sturdy for the windy condition at the site, especially with high tree. Moreover, as we discussed earlier, they will not be able to do any anchor at the planting areas that do not have planter walls. Another problem is that for this tree support system if there is anything wrong with the planter, who will be responsible?
