Abstract: There are two categories of 'unexpected' conditions inherent in a construction contract. The first are what might be regarded as normal construction risk such as labor productivity, weather, availability of materials, equipment performance and so on. The second category result from encountering differing site conditions, and/or other 'changes' not indicated or contemplated in the contract document. All of these 'unexpected' circumstances will almost certainly result in additional construction costs and more than likely increase the contractor's time of performance. The contractor rightly expects to receive an equitable adjustment to the contract price and an extension in contract time. This paper discusses the subject in terms of contract forms and provisions, differing site conditions, changes, delays, administration of contracts, and related topics.
