Allowances are amounts of money set aside in builder quotes for specific items that have not been fully determined at the time of contracting. Understanding the difference between prime cost and provisional sum allowances is critical for accurate budget planning and avoiding unexpected costs during construction. These items typically include tiles, fittings, fixtures, and materials whose exact specifications or costs cannot be determined when the contract is signed.
There are two main types of allowances in NSW building contracts:
Prime Cost Items (PC Items) in building quotes: These cover specific products, fittings, or fixtures that have not been selected or whose costs cannot be exactly determined at the time of contracting. Common examples include kitchen appliances, bathroom fixtures, tapware, door handles, and light fittings. The builder provides an allowance amount, and if the actual cost exceeds this allowance, you'll be required to pay the difference. As the homeowner, you bear the financial risk when PC allowances are set too low, making pre-contract verification of realistic allowances essential.
Provisional Sum Items (PS Items): These cover items of work, including both materials and labour, whose costs cannot be exactly determined at the time of contracting. Examples include site preparation work, excavation where ground conditions are uncertain, or connection fees to services where exact costs are unknown. Provisional sums allow for work that may be required but cannot be accurately priced initially.
Allowances significantly affect your overall project cost. If the actual cost of an item ends up being higher than the allowance specified in your contract, you as the homeowner will be required to pay the difference. This can lead to substantial cost overruns if allowances are set unrealistically low.
The use of allowances provides flexibility during the construction process, allowing you to make selections after signing the contract. However, they can be disadvantageous as they create cost uncertainty and may lead to disputes if not properly managed and documented.
It is essential for homeowners to have a thorough understanding of all allowances in their builder quotes and to ensure these are realistic and clearly documented in the building contract before signing.
