Abstract:
This research seeks to "investigate the relationship of claims in construction projects with contract’s documents and contract terms". Identifying the project’s time and activity changes, work change orders and identifying the factors that make changes, removed or added activities to the project during the work and the existence of ambiguities and deficiencies in contract’s documents and terms has been the basis for codification of two hypotheses.
The present research is a practical research that aims to investigate the relationship of claims in construction projects with contract’s document and contract terms. The research method is using a case study which is one of the varieties of scientific research methods with exploratory approach. The data gathering tool in this research is a researcher-made questionnaire. The statistical population of this research is based on the statistics of this year, are all active civil engineering companies of East Azarbaijan province (rank 4 and up) and have worked at least on three important and governmental civil projects: (N = 180).
The statistical sample of this research is 118 managers of these companies (CEO or board member): (118 = S). The sample size is extracted from the Krejcy and Morgan table. The sampling method is simple random. In the inferential analysis, we used parametric tests (one-sample t) to study the research hypotheses. All statistical calculations were performed using SPSS software.
After the investigation, it was revealed that several factors related to the documents and conditions of the contrac have significant impact on the claims. Poor project control and planning, changes in work order and large amount of change orders, contractors' exploitation of ambiguities, contract terms and bidding documents, lack of clear regulation of project implementation, contract breach, inaccuracies in cost estimation and completion time of the project, non-participation of Planners and designers in executive processes, employer and consultant engineers' interference in contract documentation, and the lack of design accuracy and specifications of work prior to the bidding have had the most impact on the claims.
