ABSTRACT
Evidence is information tending to establish the truth of facts, the facts themselves or the opinions based on those facts. In some situations, especially extension of time and disturbance of progress, the contracts are explicit in requiring the architect to deal on the basis of information provided to him or the quantity surveyor at his request by the contractor. Most disputes lie between either the employer and the contractor, or the contractor and one or more subcontractors, although some span the complete set of persons. Treatment is limited to the context of post-contract negotiation, when the parties are committed and can neither withdraw nor continue without considerable cost. Although negotiation is often seen as the confrontation of two or more individuals who have a specific arena and tasks, it may also be seen as part of a wider structure of relationships and actions.
