Benefits of Bills of Quantities
Forms of Bills of Quantities
Approximate quantities are used to provide an aligned and consistent tender when there is insufficient detail available to provide firm bills, or should the client decide that the time and cost of a full bill of quantities is not warranted. Approximate bills have descriptions reflective of the works to be completed, but the quantities are approximated.
The need to re-measure the quantities in the course of completing the works means that administering this approach is often more costly in the long run. Generally there is more variation in price when quantities are approximated. As such it is best to limit these items to uncertain elements of works such as earthworks, or instances where time restriction limits the creation of firm bills.
Firm Bills of Quantities
The most common, tried and trusted form of bills of quantities. Firm bills of quantities provide a lump sum price for the completion of works such that, if the project remained free from change, the tendered price and the final cost of the works would be one in the same. However, changes occur in the majority of projects. A completed bill of quantities gives measured rates for the various component items of the project meaning that variations may be measured and agreed at the same contract rates.
Formats and Measurement Styles
Standard methods of measurement may be followed. Many bills are still requested in Standard Method of Measurement Seven (SMM7) format in spite of the New Rules of Measurement (NRM 2) being introduced. Either is possible, or we can measure to Civil Engineering Standard Method of Measurement (CESMM3) or take on board any bespoke method of measurements you may require. Most commonly we produce Builder's Quantities on behalf of main contractors and sub-contractors.
We will usually issue our bills in PDF, Excel or CSV formats which interface with most estimating softwares. We can produce CDs or hard copies upon request.
We will generally provide a summary, and measured works sectionally measured, but can present this in pre-packaged format to suit your requirements, and include other detail to suit including Preliminaries, Risk Items, Provisional Sums, Dayworks, Credits and other addenda.
Bills of Quantities provide a clear and concise list of items that comprise the overall works, with detailed and structured descriptions. Like items are collated together to allow contractors and sub-contractors to prepare tenders with accuracy and efficiency.
To obtain a lump-sum price for carrying out the building works on behalf of the client.
Providing they are priced in a compliant fashion they provide a means for comparison of tenders, and ensure that all contractors price on a like-for-like basis.
Once a contract is in place they provide a clear basis for valuation of the work both in the case of interim payments and final accounts, and are almost essential for budgeting the works, allowing accurate cost reporting and cash flow analysis to take place.
Bills of quantities are a definitive record of the works which form part of a contract, and provide rates and descriptions for which to value variations to the original scope.
An excellent source of cost data. A completed bill may be used for cost planning of similar work, and may be used to provide supporting evidence for grants and funding claims.
