Building in Sydney Marsden Park. My builder is saying that I need to pay for reinforced concrete strip & piers because the end of the building is too (3m) close to the existing swear main in the back of the lot. This swear is already concrete encased by the land developer.
1. Provide Reinforced Concrete Strip Bridging Footings built over the top of existing sewer main. $2K
2. Provide Reinforced Concrete Piers for Bridging Footings built adjacent to the existing sewer main $2.5K
Question:
1. Is this type of concrete strip bridge footing is mandatory for building OR this is just a choice of a builder? (I am very new in building and has limited idea about structural engineering)
