The Confederation Bridge: the role of the independent engineer in theory and in practice

Abstract

The independent engineer's duties began prior to closing, starting with a rapid but comprehensive review of the developer's design criteria, concept, typical details, erection methods, estimated construction costs, and construction schedule. After closing, the independent engineer checks the design concept, including criteria, the more developed design at the equivalent of tender level, and spot checks the for construction drawings. Other duties include ongoing review of the developer's quality assurance and quality control process, certification of drawdown payments, and, unusually, continuing estimating of the cost to complete the work. Although obligations under the Independent Engineer Retainer Agreement are fulfilled, the process has had some unexpected twists, caused in large part by the demands of the construction schedule, and by the inherent difficulties of establishing design criteria. The ways in which they were handled are described.
