Covers temporary and permanent works executed in the performance of contracts, and materials for incorporation therein, plus own and hired plant, and tools and equipment while on sites or in transit. Cover is arranged for house extensions through to multi-storey office blocks. Premiums are based on annual turnover with a maximum value of any one contract. Various extensions are available (e.g. continuing hire charges following plant damage). Key exclusions relate to existing structures and defective design. Cover may have to accord with standard term contracts (e.g. Joint Contract Tribunal).
