However, it is still unknown whether which project factors have significant influence on project performance. It is essential to learn from the experiences and opinions of construction project managers who had executed innovative or alternative contracts in order to improve and refine the usage of alternative contracting methods. Innovative contracting methods have been used by state Departments of Transportation for many years, so there is now sufficient data to measure the effectiveness of these innovations. Working under a grant from the Florida Department of Transportation （FDOT）, the research team used the experiences and opinions of construction field engineers who had executed innovative contracts on FDOT projects to measure the effectiveness of these systems. To that end, interviews were conducted with FDOT and consultant personnel from across Florida. All interviewed were project managers who had overseen at least one project using an innovative contracting method. Discussions brought enthusiastic responses from those interviewed, both for and against certain innovations. This paper will focus on the experiences and opinions of those experienced construction field engineers dealing with well-known innovations, as well as newer innovations such as ＂Detour Rental＂ and ＂Damage Recovery＂.展开更多

It employs semiotic theory which approaches the interpreter’s understanding of the role of the representations used in construction documents to communicate meanings to other participants. This strategy is designed to aid the interpreters’ comprehension of the use of symbols. The symbols within the construction documents are forms of representations that take the form of a visual representation of a set of markers that describe a formal language, and of markers that are used to represent natural language as well as other possible representations, such as a collection of codes for indexing documents. Symbols are replaced by signs under the semiotics theory. The use of symbols as signs is this study’s recognition of the relationship between the interpreter and the material quality of symbols. The semiotic analysis is an examination of the compromise between the meanings of a representation per se and the concept associated with the understanding of such representation.展开更多
