13 Best General Building Contractors for Larger Projects in Singapore

Most renovation firms hold BCA's general building registration at the entry grades. This guide is for bigger jobs, where you need a contractor that BCA has cleared for higher contract values. We only included firms with a CW01 grade of B2 or above.
It's a short list on purpose. We ranked them on CW01 grade first, then years since incorporation, how many other BCA workheads they hold and how complete their record is. If your project is a flat or a small office, this list is overkill, the HDB or fit-out guides will suit you better.
How this list was ranked
Each firm gets 0 to 5 points on four things, multiplied by a weight: BCA CW01 (General Building) grade ×4, years since incorporation ×2, other BCA workheads ×2, and how complete its public record is ×1. The total is scaled to 10. We checked 13 firms and all of them are shown. Google reviews are shown as not checked until we've checked them for every firm here. Full method

Before you hire
For work at this size you'll normally go through a tender. Ask for the firm's recent projects of similar value, its safety record and its CW01 grade expiry date. Check the registration on BCA's directory yourself, it takes two minutes.
Questions people ask
What contract sizes do B2 and B1 grades allow?
BCA sets tendering limits for each grade and reviews them from time to time. Check the current limits on BCA's website, we don't repeat them here so they don't go out of date.
Why are so few firms listed?
Few companies in our records hold CW01 at B2 or above and also passed our basic checks. We'd rather show a short honest list then pad it.
