Incorporated Builders is a general contractor that has worked in Singapore since 1983, with an office in the Tong Lee Building on Kallang Pudding Road in Geylang. It is a licensed builder for general building works (Class 1) with the Building Control Authority, so it can take on whole projects rather than single trades. Its website lists residential, industrial and commercial, institutional, religious and conservation buildings, and interior decoration. The group says it has ISO 9001 quality, ISO 45001 safety and ISO 14001 environmental certification, and that it designs and builds to Green Mark and energy-efficiency ratings. It also says it has a book order of more than SGD 270 million over the past five years. One customer note is worth knowing: they want dust controlled during renovation work, with a proper dust collection system rather than plastic sheeting over the rooms. Among the eleven other builders within a kilometre, its three reviews put it in the middle of the pack, below the 4.9 of SGHalo and the 5.0 of Xin Yang Builder, but above Rk Sanitary and Plumbing. Our pick for a larger job in Geylang where the paperwork and safety records matter more than the star rating.
