Yes, it's advisable to go to the architect route and have the specifications drawn up for tender process unless you specifically knows the full process and builder well. Thanks once again for your sharing and thoughts.

Thank you Snoozee for your advise. Unfortunately pilecaps are to be done by builders and it's normally part of super-structure costing. As the foundation system (piling system) is de-coupled from the builder in this instance thus it's the builder that will need to be involved in this instance which is to constructure the pilecaps. (i might be wrong on the above but that's the interpretation I am gathering from the piling company and builder.) Most builder have a way to estimate the costing of pilecap with a buffer percentage to it (basis no of pilecaps / no of pilecaps to a pile group). The piling system costing is very clear and made know with the foundation plan upfront.

Hi All, I am in the midst of newly erecting a semi D (about 3360 sqft) I have undertook foundation system on my end away from my main builder (D&B) due to rising cost and uncertainty of the foundation system. The foundation system designed are RC piles which will be using total of 44 piles (250 X 250mm) . My main con has came back with a pilecap cost of 61K for the 44 piles (mixture of 2 piles , 3 piles ,4 piles and 5 piles to a pilecap).They have sighted pricing of pilecap is due to rising cost of raw materials, labour cost increase and large amount of manual work needed. Appreciate any advise if 61K is the fair amount for the cost of pilecap (for 44 piles) at current market. Thanking all in advance.
