After 2.5 hours long discussion with the contract person at my builder's office, we finally signed the contract and made first payment (5% contract price minus previously paid deposits for council application). Never sign/initial my name so many times in a day in my whole life. Also clarified the requirement for the tiger tail thing. According to the contract person, it's mainly for the scaffolding. Will try to get that done asap.
If weather permits, we should have the excavation started in 3 weeks time. Yeah!
