Costed: Options and opportunities for flooring

Words:
David Holmes

AECOM associate David Holmes provides an overview of floor finishes, for both capital and whole-life costs

Flooring finishes can equal 2% to 5% of the total construction cost and represent a significant investment in the overall project; they are also one of the most heavily used parts of a building, so whole-life costs are as important to consider as capital costs. A holistic approach should be adopted to deliver maximum benefits rather than focus on capital costs alone.

The following guide rates are for the supply and installation of a range of floor types. The rates should not be viewed as minimum or maximum values, rather they reflect rates typically seen in tenders received. Floor finishes offer perhaps the widest range of products and price levels.

The choice of floor types, quality and colour is truly enormous and great care needs to be given to the decisions made. Costs of the actual floor itself and any substrate requirement vary greatly. It is important to consider product properties and performance requirements relative to the intended use.

Each choice will have some effect on the price, as will the area and shape of the floor which is to be covered.

Installation
The appearance and performance of floor coverings are determined to a large extent by the quality of the prepared base or screed on which they are laid. The design and construction of the subfloor must meet the requirements for hardness, soundness, levels and surface regularities, dryness and other design parameters before whatever floor covering is chosen.

Any incompatibility with other trades or unsuitable conditions of work can restrict the ability of the floor layer to provide a neat, well adhered and satisfactory, lasting, floor finish. While the need to provide the correct material through the specification is obviously important, careful consideration must be given to on-site quality control to achieve the desired quality finish.

No allowance has been made for any attendances which may be required eg power, protection, room heating and suitable storage – which needs to be dry, clean, ventilated, waterproof, warm and secure.

Rates are a guide only and are Q12020 excluding VAT. They do not include any contractor prelims. Source Spons Architects’ and Builders’ Price Book.
