Abstract

Design changes during construction, which are typical in most projects, lead to increased cost, loss of productivity and delays. These changes are usually due to approved scope changes or due to design errors and omissions (E&Os) found in the construction documents. Errors and omissions are typically manifested in terms of incorrect or inconsistent dimensions and layouts in the construction documents, or by the lack of timely and correct information that is needed to build the project or to meet the code requirements. Among others, E&Os are usually caused by poor coordination and communication among the many parties involved in the design process. This paper explores the extent to which change orders resulting from errors and omissions in the design documents are caused
