Renovation contracts


Is there anyone based in Singapore, who knows of contracts attorney/legal team who would be able to go through contracts from renovation contractors / other specialists (like water specialist, etc), and be able to check and advise owners before signing contracts?
Generally, contracts would be written in favour of the contractor firms. Am trying to check if there's any official teams that home owners can seek help from first. In order to avoid being exploited during/at the end of the renovation journey (eg, poor job done, need repairs done due to bad workmanship/poor materials, lots of damages done, owner has little to no recourse, etc etc).
