Risk in construction contracts

'Risk', in a project delivery context, can be defined as 'an event or set of circumstances that, should it occur, will have an effect on the achievement of the project's objectives'.1 Risk exists as a consequence of uncertainty, and, in any project, the exposure to risk produced by uncertainty must be managed.2 Construction projects are often complex, highly technical and of high value, and can have construction periods that may span a number of years. Common risks prevalent in construction projects include weather, unexpected job conditions, personnel problems, errors in cost estimating and scheduling, delays, financial difficulties, strikes, faulty materials, faulty workmanship, operational problems, inadequate plans and specifications, and natural disasters.3 Projects will also have additional specific risks dependent on the nature of the project and its surrounding circumstances.

In doing so, the parties define the impact of such risks on the three key elements of the construction: the product or facility that is to be constructed by the contractor, the time at which the product or facility must be completed by the contractor and the amount the employer is obliged to pay the contractor. The collective allocation of such risks in a construction contract represents its 'risk allocation'.... Click here to download the full chapter (PDF) »
