The contractor is selected on the basis of competitive tendering on most building contracts. The price which the contractor quotes for the job is heavily influenced by both the amount and intensity of the competition expected. In an open tendering arrangement the level of the competition is at its most intense and contractors must submit highly competitive bids to have any chance of winning the contract. This usually secures a rock bottom price. With selective tendering a limited number of competent contractors are invited to tender for the job, this limited competition arrangement results in a keen price being obtained. In the case of a negotiated tender there is no explicit competition and the parties seek to agree a fair price for the work, implicit competition exists, however, as the employer can break off negotiations. If there is no competition the contractor can, in fact, name his price. The tendering arrangement is, therefore, one of the most cost significant decisions a client will make in the course of a building contract.
Insulation is an area where some look to save. Because after all, the reasoning goes, you cannot see the insulation in the walls or the attic once it is complete and who wants to spend money on things you can not see in your new home? Do not make this mistake. Not only will it translate into a lifetime of higher monthly energy bills, but it will lead to everyday discomfort with the home feeling too cold in winter and too hot in summer.
