Professional Advice
Before you start building, spend money on planning
Many people know the current price of cement but do not know the total cost of their project
That is why some projects stop at foundation level, lintel level, or roofing level
A proper Bill of Quantities tells you:
How much the project will likely cost
The quantity of materials required
The cash flow needed at each stage
Where savings can be achieved without compromising quality
Remember this:
The most expensive part of a building project is correcting mistakes that proper planning would have prevented
