Claim against a developer for failing to deliver the agreed quality

We bought a property in a project from a developer at a premium price of AED 5.4 million. Handed over was in January 2019.

We signed off the snagging as prima facie everything looked okay. Once the tenants moved in, the nightmare began. Not a day has gone by without a major issue surfacing.

Recently the switchboard caught fire and could have led to a major fire harming the tenants.

Anyway, I want to know how we can proceed to escalate the issues against the developer for not delivering as per the SPA by using cheap materials, cutting corners in fittings, structural flaws.

I just want to make sure that the developer does not get away with shoddy work. They should not take any customer for granted or for a ride and have such a callous attitude. We don't want our fate befalling others.

Appreciate the legal thoughts on the best approach to proceed with ensuring that the developer honours commitments and that proper quality check performed by the developer before handover.

Thanks in advance.
